Tax Services for Consulting Firms

Miami has become a magnet for consulting firms — management consultants, strategy shops, IT advisory practices, and solo operators who left big firms to build their own thing. The economics are straightforward: no state income tax, lower cost of living than New York or San Francisco, and proximity to Latin American markets. But the tax planning part? That’s where most consultants leave money sitting.

Entity Selection Actually Matters for Consultants

Most solo consultants in Miami start as a single-member LLC. That’s fine at $80K or $100K in revenue. But once you’re billing $200K, $400K, or more, staying as a disregarded entity means you’re paying 15.3% self-employment tax on every dollar of profit up to the Social Security wage base ($176,100 in 2025), plus 2.9% Medicare tax on everything above that.

An S-corp election fixes this. Pay yourself a reasonable salary — say $130K for a management consultant billing $350K — and the remaining $220K flows through as a distribution, free of self-employment tax. That’s roughly $6,300 in annual savings on the FICA side alone. Multiply that over five years and you’re looking at $30K+ that stayed in your pocket instead of going to payroll taxes you didn’t owe.

The catch: you have to run actual payroll, file Form 1120-S annually, and keep your books clean. We set all of this up and handle it ongoing.

Travel, Home Office, and Client Entertainment

Consultants travel. A lot. Flights to client sites, hotels, rental cars, meals during overnight travel — all deductible. But the rules have details that trip people up. Business meals are 50% deductible in 2025. Entertainment (concert tickets, golf outings) is still zero, no matter how much business you discussed on the back nine.

The home office deduction is worth claiming if you have dedicated space. The simplified method gives you $5 per square foot, up to 300 square feet ($1,500). The actual expense method usually yields more — especially in Miami where rent and utilities aren’t cheap — but requires tracking real costs and calculating the business-use percentage of your home.

Quarterly Estimated Taxes and Cash Flow Planning

Consulting income is lumpy. You might bill $80K in Q1 and $30K in Q2. The IRS doesn’t care. They want quarterly payments based on either 100% of last year’s tax (110% if your AGI exceeded $150K) or 90% of this year’s liability.

Miss a quarterly payment and you’ll owe an underpayment penalty — currently running around 7% annualized on the shortfall. It’s not huge, but it’s avoidable. We calculate your quarterly estimates based on your actual billing pipeline, not just a flat “divide last year by four”. Approach that doesn’t match reality.

Multi-State Filing When You Work Across State Lines

Here’s where Miami consultants get surprised. Florida has no income tax, but if you’re flying to New York for a two-week engagement, New York wants a piece of your income for those days. Same with California and most other states with an income tax. The calculation is typically based on duty days — the proportion of your working days spent in that state.

A consultant earning $400K who spends 30 days in New York could owe $4,000 to $6,000 in NY state taxes on that allocation alone. We track this and file the non-resident returns so you’re not caught off guard, and we make sure you’re not double-paying on income already taxed elsewhere.

Frequently Asked Questions

When should I switch from LLC to S-corp?

The conversation about switching from a single-member LLC to an S-corp usually starts when a Miami consultant’s net business income crosses the $60,000 to $80,000 threshold. Below that range, the added costs of running an S-corp—payroll processing fees, an additional tax return (Form 1120-S), and higher accounting fees—tend to offset the tax savings. Above it, the savings become significant enough to justify the extra administrative burden.

To understand why, you need to know what changes from a tax perspective. As a single-member LLC (without any election), you’re treated as a sole proprietor for federal tax purposes. All your net business income flows to your personal return on Schedule C and is subject to self-employment tax at 15.3% (Social Security plus Medicare) on the first $168,600 of net earnings, then 2.9% Medicare tax above that, plus 0.9% Additional Medicare Tax on earnings over $200,000. On $200,000 of net consulting income, your self-employment tax bill is roughly $26,000.

When you elect S-corp status (by filing Form 2553 with the IRS), your LLC keeps its legal structure but changes its tax treatment. Now you’re required to pay yourself a “reasonable salary”. Through payroll and take the rest as distributions. Payroll taxes apply only to the salary portion. If you set your salary at $100,000 and take $100,000 in distributions, you pay payroll taxes on $100,000 instead of $200,000. That’s about $15,300 in payroll taxes versus $26,000—a savings of roughly $10,700. After accounting for $2,000-$4,000 in additional annual costs, you’re still netting $7,000 to $9,000 in savings.

Florida’s tax-friendly environment amplifies the benefit. There’s no state income tax, so the payroll tax savings flow straight to your bottom line without being partially offset by state-level complications. Compare that to a California or New York consultant, who needs to factor in state franchise taxes, entity-level taxes, and more complex filing requirements. In Florida, the S-corp election is cleaner and cheaper to maintain.

The “reasonable salary”. Requirement is where most consultants get nervous, and rightly so. The IRS has been increasing scrutiny of S-corp owners who pay themselves unreasonably low salaries to make the most of the distribution (non-taxable-for-payroll-purposes) portion of their income. For a management consultant in Miami, a reasonable salary depends on your experience, specialization, hours worked, and what comparable consultants earn in the market. Based on industry data, most solo consultants should be paying themselves between $70,000 and $150,000, with the specific number reflecting your actual role and workload.

The mechanics of switching are straightforward. You file Form 2553 with the IRS—it’s a two-page form that must be submitted by March 15 of the year you want the election to take effect. You can also file within 75 days of forming your LLC if it’s a new entity. Once the election is accepted, you need to set up payroll (we recommend using Gusto or ADP for simplicity), open a separate business checking account if you haven’t already, and start processing regular payroll runs with proper tax withholdings.

Timing matters. The best approach is to plan the switch in Q4 of the prior year so everything is in place for January 1. Mid-year switches create complications—you’d need to split your tax year between sole proprietor treatment and S-corp treatment, which adds complexity and cost to your tax return. If you’ve missed the March 15 deadline, late election relief is available under Revenue Procedure 2013-30, but it requires demonstrating reasonable cause for the late filing.

One additional benefit of S-corp status in Florida: it positions you for a Solo 401(k). Through the S-corp, you can contribute as both employee and employer, with total contribution limits of $69,000 in 2024 ($76,500 if over 50). These contributions reduce your taxable income dollar-for-dollar, compounding the tax savings from the S-corp election itself. Check out our S-corp tax guide for a full breakdown of the process and the numbers.

There’s also the retirement planning advantage that makes the S-corp election even more attractive in a no-income-tax state. With a Solo 401(k) through your S-corp, you can contribute up to $70,000 per year ($76,500 if you’re over 50). Every dollar you put in reduces your federal taxable income without any state tax complication—because Florida has no state income tax to interact with. In California or New York, retirement contributions reduce both federal and state taxes, but the state tax savings are partially offset by the state-level entity taxes. In Florida, it’s pure federal savings. At a 37% marginal rate, a $69,000 Solo 401(k) contribution saves you $25,530 in federal taxes.

We should also mention the Qualified Business Income (QBI) deduction under Section 199A. If your consulting income qualifies, you can deduct up to 20% of your qualified business income on your personal return. For a consultant earning $200,000 through an S-corp, that could mean an additional $40,000 deduction—saving $14,800 in federal taxes. But the deduction phases out above certain income thresholds and is subject to wage and capital limitations, so the actual benefit depends on your salary level, total income, and filing status. This is another area where the “reasonable salary”. Calculation has downstream effects on other deductions—getting the number right requires modeling the interaction between payroll taxes and retirement contributions.

The bottom line for Miami consultants: the S-corp election is one of the most powerful tax-saving tools available to you, and Florida’s tax-friendly environment makes it even more effective than in most other states. If your net business income consistently exceeds $60,000 to $80,000, you should be having this conversation with a tax professional who can run the actual numbers for your specific situation.

We should also mention the administrative side of running an S-corp, because it’s not just about filing Form 2553 and calling it a day. You need to maintain corporate formalities: keep meeting minutes (even if you’re a solo consultant, document annual resolutions), maintain a separate business bank account, avoid commingling personal and business funds, and pay yourself through a legitimate payroll system. The IRS can pierce the S-corp election and reclassify all distributions as wages if you fail to maintain proper corporate formalities or treat the entity like a personal piggy bank.

Florida also requires an annual report filing with the Division of Corporations by May 1 each year, with a filing fee of $138.75 for LLCs and $150 for corporations. Miss it and you face a $400 late fee. Miss it long enough and the state will administratively dissolve your entity, which creates a cascade of problems with bank accounts and client contracts. We calendar every compliance deadline for our clients so nothing gets missed.

Can I deduct my co-working space membership?

Yes, and it’s one of the most straightforward deductions available to Miami-based consultants. Your co-working space membership—whether it’s a hot desk at WeWork, a dedicated desk at a local space, or a private office at Spaces or Industrious—is a fully deductible business expense, no different from renting a traditional office. You claim it on Schedule C (if you’re a sole proprietor) or as a business expense flowing through your S-corp or LLC.

The deduction covers the full membership fee you pay. If your dedicated desk costs $450 per month, that’s $5,400 per year in deductible business expenses. A private office at $1,200 per month is $14,400. Even a basic hot desk membership at $200 per month gives you a $2,400 annual deduction. At a combined federal marginal tax rate of 32-37% for most consultants (plus self-employment tax savings if you’re still a sole proprietor), the tax savings can offset 40-45% of the actual cost of the membership.

But here’s where it gets interesting for consultants who also work from home. You can claim both a co-working space deduction and a home office deduction simultaneously—but only if you meet the requirements for both. The home office still needs to be a dedicated space used regularly and exclusively for business. If you spend three days a week at the co-working space and two days working from your home office, both deductions are valid. The co-working membership is deductible in full as a rent/office expense, and the home office deduction is calculated based on your regular and exclusive use of the dedicated home space.

This dual-deduction strategy is particularly valuable in Miami where rents are high. Say you’re paying $3,200 per month in rent for a two-bedroom apartment and using the second bedroom exclusively as an office. The office takes up about 25% of the apartment’s square footage. Under the regular method, you can deduct 25% of your rent ($800/month = $9,600/year), plus 25% of utilities and renter’s insurance. Add in a $450/month co-working membership ($5,400/year), and your total workspace deduction is over $15,000 annually. At a 40% effective tax rate, that’s $6,000 in real tax savings.

There are some nuances to watch for. If your co-working space membership includes perks like gym access, event attendance, or meals, the IRS could argue that a portion of the membership covers personal benefits. In practice, this rarely comes up for standard co-working memberships, but if your space advertises heavily around lifestyle perks, keep records showing you’re using the space primarily for business work. A log of the days and hours you work at the space (easily documented through key card swipes, Wi-Fi login records, or your own calendar) provides solid backup.

Conference room bookings and meeting space fees at the co-working space are separately deductible as business expenses. If you pay $50 per hour for a conference room to meet with a client, that’s a deductible cost on top of your base membership. Day passes purchased for clients or collaborators visiting your co-working space are also deductible—just document the business purpose.

For S-corp owners, the co-working membership should be paid directly by the S-corp (from the business bank account or business credit card) and recorded as a rent or office expense on the company’s books. Don’t pay for it personally and seek reimbursement—while that technically works under an accountable plan, it’s cleaner to have the business pay directly. This also makes it easier for your bookkeeper to categorize and for your CPA to prepare the tax return.

Parking at the co-working space is another deductible expense that consultants often forget about. In Miami, especially in areas like Brickell, Wynwood, or the Design District, parking can run $200-$400 per month. If you’re paying for parking to access your co-working space, that’s a legitimate business transportation expense. Same goes for tolls on the expressway if your commute to the space involves toll roads. Track these costs and categorize them as business transportation expenses in your accounting system.

One last thing: if you’re considering upgrading from a hot desk to a private office, run the tax math first. The incremental cost might be lower than you think after the tax deduction. Moving from a $250/month hot desk to a $1,000/month private office costs $750 more per month—but after the tax deduction at a 40% rate, the effective after-tax cost is only $450/month. For many consultants, the productivity gain from having a private, quiet workspace easily justifies that net cost. Let us model it alongside your other deductions so you can see the full picture.

There are also tax implications to how you pay for the membership. If your S-corp pays for the co-working space directly (using the business credit card or checking account), it’s a straightforward business expense on the S-corp’s books. But if you pay personally and want to be reimbursed, you’ll need an accountable plan in place. Under an accountable plan, the S-corp reimburses you for the expense, the reimbursement is not taxable to you, and the S-corp gets the deduction. Without an accountable plan, personal reimbursements can be treated as additional compensation—triggering payroll taxes. Most of our clients keep it simple by having all business expenses paid directly from the business account.

A few additional deductions that Miami consultants using co-working spaces often overlook: the cost of a dedicated phone line or virtual mailbox service provided by the co-working space is separately deductible. Printing and copying charges billed by the co-working space are deductible. Event space rentals for client workshops or team meetings are deductible. And if you purchase coffee, snacks, or meals at the co-working space’s cafe, those are potentially deductible as either employee meals (if you’re eating alone while working—generally not deductible unless traveling) or business meals (if you’re dining with a client or business contact—50% deductible with proper documentation of the business purpose).

The key takeaway is to track everything. Your co-working membership receipt alone isn’t enough—you should also document any ancillary expenses charged by the space, maintain records of your attendance for the home office dual-deduction argument, and keep your personal and business spending at the space clearly separated in your accounting system.

I have subcontractors. What do I need to do at tax time?

Using subcontractors is standard practice for Miami consulting firms—it lets you scale up for large projects without the overhead of full-time employees. But subcontractors create specific tax obligations that you need to handle correctly, because the penalties for getting it wrong are steep. The IRS and Florida’s Department of Revenue both take worker classification seriously, and mistakes in this area generate some of the most expensive audit assessments we see.

The most important thing you need to do is issue a Form 1099-NEC to every subcontractor you paid $2,000 or more during the calendar year. The filing deadline is January 31—there’s no extension. You also need to file Copy A with the IRS by the same date. If you used an electronic filing service (which we recommend for anyone with more than a handful of subcontractors), the IRS submission happens automatically. But you must have the forms prepared and mailed or electronically delivered to the contractors by January 31.

To issue a 1099-NEC, you need the contractor’s legal name and Taxpayer Identification Number (TIN)—either their Social Security Number or Employer Identification Number. You should collect this information before you make the first payment by having every subcontractor complete a Form W-9. Do not skip this step. If you pay a subcontractor $10,000 and don’t have their TIN, you’re required to withhold 24% backup withholding ($2,400) and remit it to the IRS. Most consultants don’t do this, which creates a compliance problem when the 1099 is due and you can’t fill in the TIN field.

The worker classification question is the biggest trap in this area. The IRS applies a multi-factor test (sometimes called the “common law”. Test or the “20-factor”. Test) to determine whether someone is a true independent contractor or actually an employee you’re misclassifying. The factors fall into three categories: behavioral control (do you control how the worker does the job?), financial control (does the worker have a significant investment in their own tools, bear risk of profit or loss, and serve other clients?), and relationship type (is there a written contract specifying independent contractor status, and is the relationship intended to be temporary?). No single factor is determinative—the IRS looks at the overall picture.

For consulting firms, the classification risk is highest when you have a subcontractor who works exclusively for you, uses your equipment and software, works regular hours at your direction, and doesn’t market their services to other clients. That pattern looks a lot like employment, and if the IRS or Florida DEO reclassifies the worker as an employee, the consequences are brutal. You’d owe back employment taxes (the employer’s share of Social Security and federal unemployment taxes) plus penalties, which typically add up to 30-40% of the total payments made to the misclassified worker. On $80,000 in payments, that’s a potential assessment of $24,000 to $32,000 per worker.

To protect yourself, structure every subcontractor relationship to clearly look like what it is. Use a written independent contractor agreement that spells out the scope of work, the work and payment terms. Pay by project or milestone, not by the hour (hourly pay looks more like employment). Don’t provide the subcontractor with your firm’s email address, business cards, or equipment. Let them control where and when they work. And most make sure they’re serving other clients—a contractor who works exclusively for one firm is the IRS’s textbook example of a misclassified employee.

On the bookkeeping side, you should track all subcontractor payments in a dedicated expense category in your accounting system. This makes 1099 preparation much easier at year-end and gives you a clean record if audited. Most accounting platforms (QuickBooks, Xero, FreshBooks) can generate 1099s automatically if you’ve properly categorized payments and entered the contractors’ W-9 information throughout the year.

One more important deadline: Florida requires businesses that pay subcontractors $600 or more to report those payments for reemployment tax purposes. While Florida doesn’t have a state income tax, it does have a reemployment (unemployment) tax system, and the state cross-references your 1099 filings to verify that you’re not misclassifying employees as contractors to avoid paying reemployment tax. If you’re flagged for a classification audit, the state can reclassify workers going back up to three years. Talk to us if you’re uncertain about how any of your subcontractor relationships should be classified—it’s much cheaper to get it right upfront than to fix it after an audit.

There’s one more scenario that Miami consulting firms encounter frequently: international subcontractors. If you hire a freelancer based outside the United States—say, a virtual assistant in the Philippines or a designer in Colombia—you don’t issue a 1099-NEC. Foreign contractors who perform services outside the U.S. are not subject to 1099 reporting. However, if a foreign contractor performs work while physically present in the United States, different rules apply, and you may need to withhold 30% of payments under the Foreign Account Tax Compliance Act (FATCA) unless the contractor provides a Form W-8BEN claiming treaty benefits. This area is complex enough that we recommend consulting with a tax professional before making your first payment to an international contractor.

The deductibility of subcontractor payments is straightforward—payments to contractors for business services are fully deductible as an ordinary and necessary business expense. But you need to report them correctly. If you deduct $50,000 in subcontractor payments on your Schedule C or Form 1120-S but don’t issue the corresponding 1099s, the IRS will flag the discrepancy. Their systems are automated and they cross-match deductions against 1099 filings routinely. Getting caught results in both the 1099 penalty and increased scrutiny of your return in general.

For consulting firms that rely heavily on subcontractors, we recommend a quarterly compliance check rather than leaving everything to year-end. At the end of each quarter, review your subcontractor payments, verify that you have current W-9s on file for everyone, and update your running total of payments per contractor. This takes about 20 minutes per quarter and completely eliminates the January scramble. We build this quarterly check into our standard engagement with Miami consulting clients.

Do I need to charge Florida sales tax on my consulting services?

For pure consulting services—advising clients, developing strategies, providing expert opinions—the answer is almost always no. Florida’s sales tax applies to tangible personal property and certain specified services, but professional consulting services are not on the taxable list. If your business involves giving advice, creating plans, coaching executives, or providing management guidance, you’re selling a non-taxable service and you don’t need to collect or remit Florida sales tax.

That said, Florida’s sales tax rules have several traps that consulting firms fall into, especially firms that offer services adjacent to or bundled with taxable items. Understanding where the line sits can save you from an unexpected assessment during a Florida Department of Revenue audit.

The most common trap for consultants is the “information services”. Carve-out. While Florida doesn’t currently tax information services the way New York does, certain data-related products can fall under taxable categories. If your consulting deliverable includes providing market data, proprietary databases, or subscription-based information products, those components might be treated as taxable tangible personal property or taxable communication services depending on how they’re delivered. The key question is whether the customer is paying for your professional judgment or for access to data. The former is exempt. The latter may not be.

Another area that catches consultants off guard is software. If your consulting firm also licenses or sells software—even if it’s a small part of your business—the software component is taxable in Florida. Florida taxes “the sale, rental, lease, or license to use prewritten software”. And specifically includes remotely accessed software (SaaS) in its taxable base. So if you’re a management consultant who also offers clients access to a proprietary dashboard or reporting tool, the license fee for that tool is taxable even though your consulting time is not. You need to separately state the software component on your invoices to avoid having the entire engagement treated as taxable.

Training services are another gray area. If you conduct training sessions as part of a consulting engagement—onboarding workshops, process training, executive coaching—those services are generally exempt from sales tax in Florida. But if you sell pre-recorded training content (videos, courses, e-learning modules) on tangible media or as downloads, that could be treated as a taxable sale of tangible personal property or a taxable digital product. The distinction between live training (exempt) and pre-packaged training content (potentially taxable) is one that the Department of Revenue has ruled on inconsistently, so it’s worth getting a formal opinion if pre-recorded content is a significant part of your revenue.

Commercial rent is the one Florida tax that universally applies to consulting firms with office space. Florida imposes a state sales tax of 5.5% (reduced from the standard 6% for commercial leases) plus the local discretionary surtax on commercial lease payments. In Miami-Dade County, the combined rate comes to about 6.5-7% depending on the specific municipality. If you’re leasing office space at $3,000 per month, you’re paying an extra $195-$210 per month in sales tax on the rent alone. This isn’t a tax you collect from your clients—it’s a tax the landlord collects from you. But it’s a legitimate business expense that you deduct on your tax return.

For consulting firms with clients in other states, the sales tax analysis gets more complicated because each state has its own rules. Some states that tax consulting services include Texas (which taxes certain data processing and information services), New Mexico (which broadly taxes services), Hawaii (which taxes virtually everything), and Washington (which taxes services under its B&O tax rather than traditional sales tax). If you’re a Miami consultant billing clients in any of these states, you may have sales tax collection obligations there once you cross the economic nexus threshold—typically $100,000 in sales or 200 transactions into the state during the current or prior calendar year.

The bottom line for most Miami consulting firms: you don’t need to charge Florida sales tax on pure consulting services, but watch the boundaries around software, data products, and bundled offerings. And pay attention to your commercial rent—it’s subject to sales tax, and landlords are required to collect it. See our LLC tax guide for more details on how Florida treats different business structures and their sales tax obligations.

It’s also worth knowing that Florida has been actively expanding its sales tax base in recent years, and there’s always a risk that consulting services could be added to the taxable list in the future. Several states have proposed (and in some cases enacted) broader services taxes as part of their revenue diversification strategies. While there’s no current legislation in Florida targeting consulting specifically, it’s something to monitor—especially as the state’s population and revenue needs continue to grow.

For consultants who also sell physical products alongside their services—say, you’re a marketing consultant who also sells branded merchandise to clients, or an IT consultant who resells hardware—those tangible goods are unambiguously subject to Florida’s 6% sales tax plus the local discretionary surtax. You need to register with the Florida Department of Revenue, collect tax on taxable sales, and file returns (monthly, quarterly, or annually depending on your volume). The registration process is free and takes about 10 minutes online, but operating without a sales tax registration while making taxable sales can result in penalties of 10% of the tax due (minimum $50) plus interest at 12% annually.

One more nuance: if you’re providing consulting services as part of a larger bundled transaction that includes taxable components, Florida follows the “true object”. Test. The tax authority looks at what the customer was really purchasing—if the true object is the consulting service and the taxable component is incidental, the entire transaction might be exempt. But if the taxable component is substantial or separately stated, the tax applies to that portion. Clear invoicing that breaks out the consulting fees from any tangible or software components is your best defense against an auditor bundling everything together and taxing the whole amount.

We advise all our Miami consulting clients to do an annual sales tax review as part of their tax planning engagement. It takes about 30 minutes and ensures you’re collecting where required, not collecting where you shouldn’t be, and documenting everything properly for audit defense.

What quarterly tax deadlines should Miami consultants know about?

Missing a quarterly deadline is one of the most expensive mistakes a self-employed consultant can make, and it happens more often than you’d think. Between federal estimated taxes, Florida’s reemployment tax, and various filing obligations, there are at least a dozen deadlines scattered throughout the year. Miss one and you’re looking at penalties and in some cases a revoked business registration. Here’s the full calendar you need to track.

The big four are your federal estimated tax payments, due on April 15, June 15, September 15, and January 15 (of the following year). These are the quarterly payments covering your income tax and self-employment tax on business earnings that don’t have withholding. If you’re a sole proprietor or a single-member LLC, you calculate these payments using Form 1040-ES. If you’re an S-corp owner, your salary will have withholding that covers part of your tax obligation, but you’ll still owe estimated taxes on the distribution portion of your income. The safe harbor to avoid underpayment penalties is paying either 100% of your prior-year tax liability or 90% of your current-year liability (110% of prior year if your AGI exceeds $150,000).

The penalties for underpaying estimated taxes are essentially interest charges. The current federal underpayment rate has been running between 7% and 8%—significantly higher than a few years ago. On a $10,000 quarterly underpayment, that’s roughly $175-$200 in penalties per quarter. Not catastrophic, but it adds up over four quarters and multiple years. More underpayment penalties are automatic—the IRS computes them when you file your return and sends you a bill. There’s no discretion or appeals process for basic estimated tax penalties.

If you run an S-corp with payroll, you have additional quarterly obligations. Federal payroll tax deposits are due on a semi-weekly or monthly schedule depending on your total payroll tax liability (most small consulting firms fall into the monthly deposit schedule). Quarterly payroll tax returns—Form 941—are due by the last day of the month following each quarter: April 30, July 31, October 31, and January 31. Late filing of Form 941 triggers penalties of 5% per month (up to 25%) on the tax due, and late deposit penalties range from 2% to 15% depending on how late you are.

Florida’s reemployment (unemployment) tax adds another quarterly obligation. If you have employees (including yourself as an S-corp employee), you’re required to file Florida Form RT-6 and pay reemployment tax quarterly. The due dates are April 30, July 31, October 31, and January 31. The tax rate varies based on your company’s experience rating, but new employers in Florida typically start at 2.7% on the first $7,000 of each employee’s wages. That’s a maximum of $189 per employee per year—not a big number, but the penalty for not filing is $25 per quarter per late report plus interest on unpaid tax.

Annual deadlines round out the calendar. Your personal tax return (Form 1040) is due April 15 with an automatic extension available to October 15. If you’re an S-corp, Form 1120-S is due March 15 with an extension to September 15. Late filing of the S-corp return carries a penalty of $220 per shareholder per month (2024 rate), up to 12 months. For a single-shareholder S-corp, that’s $2,640 if you miss the deadline and forget to file an extension. Always file the extension even if you’re not ready to file the return—it costs nothing and eliminates the late filing penalty.

W-2s (for employees, including yourself) and 1099-NECs (for subcontractors) are both due by January 31. No extensions are available for 1099-NEC. The penalty for late filing is $60 per form if filed within 30 days of the deadline, $120 per form if filed by August 1, and $310 per form after that. For a consulting firm with 10 subcontractors, that’s up to $3,100 in penalties for late 1099 filings.

We set up automated reminders for every deadline—federal and local—for our consulting clients during onboarding. Most of these filings can be automated or at least partially pre-filled if your bookkeeping is current throughout the year. The consultants who get into trouble are the ones who let their books fall behind, then scramble to reconstruct everything at year-end and miss filing deadlines in the process. Stay current on your bookkeeping, and the quarterly filing process takes less than an hour per quarter.

There’s an additional deadline that trips up S-corp consultants who are also Florida LLCs: the Florida Annual Report. Every LLC and corporation registered in Florida must file an Annual Report with the Division of Corporations by May 1 each year. The filing fee is $138.75 for LLCs and $150 for corporations. If you miss the May 1 deadline, there’s a $400 late fee on top of the filing fee. And if you don’t file by the third Friday in September, the state administratively dissolves your entity. We’ve seen consultants let this slide and suddenly discover their LLC no longer legally exists—which creates problems with everything from bank accounts to client contracts to insurance policies.

For consultants who operate in multiple jurisdictions, there may be additional quarterly deadlines in other states. If you have clients in New York and earn enough there to trigger nexus, you’ll owe New York State estimated tax payments on the same quarterly schedule as federal estimates. Same for California, Illinois, or any other income tax state where you have filing obligations. Each state sets its own underpayment penalty rates and safe harbor rules, so you need to calculate estimated payments for each state independently.

The simplest way to manage all of this is to work with an accounting firm that handles it for you—not just the preparation, but the calendar management and reminder system. We maintain a master compliance calendar for every client that includes every federal and local deadline, with automated reminders 30 days and 7 days before each due date. That way you never pay a penalty for missing a deadline you didn’t know about, and you can focus on running your consulting practice instead of tracking paperwork. If your current setup doesn’t include proactive deadline management, that’s a gap worth filling before it costs you money.
