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, Illinois, 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.

Common Questions

When should I switch from LLC to S-corp?

The general rule: once your net profit consistently exceeds $60K to $80K annually. Below that, the cost of running payroll and filing the extra return may outweigh the self-employment tax savings. Above it, the math almost always favors the S-corp election. We’ll model it with your actual numbers.

Can I deduct my co-working space membership?

Yes. A co-working space used for business is a deductible business expense — rent, just like any other office lease. If you also have a home office, you can deduct that too, as long as both are used regularly and exclusively for business.

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

If you pay any individual or unincorporated entity $600 or more in a calendar year, you’re required to issue a Form 1099-NEC by January 31. Miss the deadline and you could face $60 to $310 per form in penalties, depending on how late you file. We handle 1099 prep and filing as part of our service.

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

Generally, no. Professional services like management consulting, strategy advisory, and IT consulting are not subject to Florida sales tax. But if you’re bundling tangible products with your services (like delivering hardware as part of an IT engagement), the product portion may be taxable.
