IRS Audit & Refund Notice Assistance for Real Estate Investors and Landlords in Miami

Rental losses draw attention because of how they work, not because you did anything wrong, and understanding that helps you keep the position defensible from the start. A rental can show a loss on your Schedule E even when it puts cash in your pocket, because depreciation is a deduction you take without spending money that year. The IRS sees a paper loss offsetting other income and asks a simple question, is this loss actually allowed against that income, because the default rule says it is not.

The default is the passive activity loss rule in IRS Publication 925. Rental real estate is passive by default, so its losses can only offset passive income, not your wages or business profit. When a return uses a large rental loss to wipe out wage income, the taxpayer is almost always claiming one of two exceptions, the $25,000 active-participation allowance, which phases out between $100,000 and $150,000 of income, or full real estate professional status, which removes the passive limit entirely. The second one is the audit magnet, because it requires meeting strict hour thresholds, more than 750 hours and more than half your working time in real property trades, and the IRS frequently asks the taxpayer to prove those hours. The active-participation allowance draws less scrutiny because it is capped and phases out, but even there the examiner may test whether you truly made management decisions, so both exceptions rest on records rather than assertions.

Miami shapes the profile in a specific way. South Florida attracts high earners, second-home buyers, and out-of-state investors, and the classic real estate professional claim, one spouse with a high salary and the other managing a cluster of rentals, is common here and well known to examiners. High property values also mean the depreciation deductions themselves are large in absolute dollars, so a Miami rental loss looks bigger to the matching software than the same activity would in a cheaper market, and size is one of the things that moves a return up the selection list. What Miami does not add is a second taxing authority on the income side, because Florida has no state income tax, so unlike a California landlord who could face both the IRS and the state on the same loss, a Miami owner defends the position with the IRS alone.

Here is a worked example. A household has $400,000 of wage income and claims a $70,000 rental loss as non-passive under real estate professional status. If allowed, that loss saves federal tax in a high bracket, easily more than $20,000, and because there is no Florida income tax the whole benefit is federal. That is precisely why the IRS wants to see a contemporaneous log proving the managing spouse actually spent more than 750 hours and more than half their working time on the rentals. If the log exists and is credible, the position holds. If it is reconstructed after the notice arrives, it is weak, because courts have repeatedly rejected after-the-fact estimates built from calendars and guesses. A log that records the date, the property, the task, and the hours as the work happens is worth far more than a polished summary written the week the audit letter lands. We build the hour logs and material-participation records before the return is filed, keep them the way the rules require, and if an examination comes, we present the loss with the evidence behind it, coordinating the defense through our tax strategy consulting so you are not proving a year of hours from memory.

A cost segregation study is defensible when it is built and documented correctly, and our job is to make sure it is that way before you ever file, because a big first-year depreciation deduction is a flag and the defense is only as strong as the report behind it. Cost segregation works by taking a building you would otherwise depreciate over 27.5 or 39 years and identifying the components that actually qualify for shorter 5, 7, and 15 year lives, such as certain fixtures, flooring, and land improvements, which can then be written off faster and often qualify for bonus depreciation. Done right, it accelerates real deductions you are entitled to. Done loosely, it invites an adjustment.

The IRS accepts cost segregation, and it has published guidance on how it should be done, favoring an engineering-based study performed by qualified professionals who inspect the property and document why each reclassified component belongs in a shorter recovery class. The studies that get challenged are the ones that assign aggressive percentages without engineering support, use rules of thumb instead of analysis, or rest on a purchase-price allocation that overstates the building and understates the land. In Miami that land-versus-building split is sensitive too, because waterfront and Brickell land values are high, so an allocation putting too little on the land is exactly the kind of thing an examiner questions first. So the defense begins with commissioning the right kind of study and keeping the full report, not just the summary number that flowed onto the return.

There is a second layer that landlords have to watch, the passive loss interaction. Accelerating depreciation creates a larger loss, but that loss is still passive unless you qualify as a real estate professional, so front-loading depreciation without the status can leave the deduction suspended rather than usable this year. A study that produces a huge paper loss you cannot currently use is a poor trade if it cost you real money, so we check the participation picture before recommending one. It can still make sense when you have passive income to absorb the loss or a sale on the horizon that will release it, but that is a judgment to make before the study, not after.

Here is where Miami is simpler than a non-conforming state. Florida has no income tax, so there is no separate state depreciation schedule, no state that refuses to follow federal bonus depreciation, and no state basis difference to track and defend. In California, the same study that generates a large federal deduction generates only a small state one and creates a multi-year reconciliation between two different depreciation numbers. In Florida there is only the federal number, so the study is easier to carry after it is done, because the sole authority that might question it is the IRS, confirmed by the depreciation rules in IRS Publication 946.

Here is a worked example. On a $1.2 million apartment building, a cost segregation study reclassifies $260,000 into shorter-life property eligible for 100 percent bonus depreciation, producing a $260,000 first-year federal deduction. In an examination, the IRS may ask to see the engineering report supporting that $260,000, the basis allocation between building and land, and, if you used the loss against non-passive income, the real estate professional substantiation. Unlike a California owner, you do not also have to reconcile a smaller state deduction or carry a separate state basis forward, because Florida does not tax the income at all. We keep the engineering study and the depreciation schedules on file, so if the IRS questions the deduction, the answer is a documented report rather than an argument, and we manage that defense through our tax strategy consulting.

The first thing to know is that a CP2000 is usually not an audit and often not even correct, so the right response is a careful reconciliation, not a panicked payment. A CP2000 is an automated notice the IRS sends when the income reported on your return does not match the income third parties reported about you. For a landlord, that mismatch typically comes from a form reporting rental payments, a 1099-MISC from a property manager or a tenant business, or a 1099-K from a rental platform. The notice proposes additional tax on the difference and gives you a deadline to agree or explain, usually about 30 days from the date on the letter, and the IRS explains the process in its guidance on understanding a CP2000 notice.

The reason these notices are so often wrong for landlords is that the IRS computer sees gross figures and does not see your deductions or the character of the money. A 1099 may report the gross rent a manager collected, while your return correctly reported the rent net of the manager’s fees, repairs, and other costs paid out of that gross. A 1099-K from a platform may report gross bookings before the platform’s fees and before any transient tax it remitted. A security deposit you received might be swept into a reported total even though it is a liability and not yet income. In each case the difference is a presentation or timing issue, not unreported income, and the answer is a schedule that ties the form to what you reported.

Miami makes the 1099-K version of this especially common, because so many owners run short-term rentals through booking platforms. The platform’s 1099-K reports the gross amount guests were charged, which includes the platform’s service fee and, critically, the Florida sales tax and Miami-Dade tourist tax the platform may have collected and remitted on your behalf. None of that is your taxable rental income, so the gross on the 1099-K can be far higher than the rent you correctly reported. The 1099 rules also changed for 2026, with the general 1099-NEC and 1099-MISC threshold rising from $600 to $2,000 and the 1099-K threshold restored by OBBBA to more than $20,000 and more than 200 transactions, so a mismatch can also arise simply from how a payer applied a threshold or from a corrected form filed after you filed your return.

It also matters how you respond. You do not simply pay the proposed balance if you disagree, you return the response form marking that you disagree and attach the reconciliation and copies of the supporting records. If you ignore the notice, the IRS follows the CP2000 with a statutory notice of deficiency, and once that lands your options narrow to paying or petitioning the Tax Court, so answering the CP2000 on time is what keeps the matter easy to resolve.

Here is a worked example. You receive a CP2000 claiming $22,000 of unreported rental income because a booking platform filed a 1099-K reporting $22,000 of gross guest charges for your Miami short-term rental. Your return, though, reported that property’s income net of the platform’s service fee and net of the Florida sales tax and county tourist tax the platform collected and remitted, so the number on your Schedule E is well below $22,000 by design. This is not additional income, it is gross booking revenue that included fees and taxes that were never yours. We respond with a reconciliation schedule showing the $22,000 gross, the platform fee subtracted, the transient taxes subtracted, and the net rent that appears on your return, so the IRS sees the full picture and closes the notice with no change. If part of the notice is right, we agree to that part and dispute the rest. Either way we answer before the deadline, and we keep the underlying records straight through your bookkeeping so the reconciliation is quick to build.

This is the notice unique to Florida, and it surprises owners who moved here for the no-income-tax reputation, because while Florida does not tax your rental income, it very much taxes short-term rental stays through sales and use tax, and the Florida Department of Revenue audits operators to collect it. A real estate investor CPA has to treat this as a real enforcement risk, not a formality, because the liability is yours as the owner and the state can reach back several years. The taxes involved are administered by the Florida Department of Revenue for the state portion and by Miami-Dade County for the local tourist tax.

Start with what is taxable. Florida treats the rental of living accommodations for six months or less as a transient rental subject to state sales tax at 6 percent, plus the Miami-Dade discretionary sales surtax, and Miami-Dade layers its tourist development tax, the bed tax, on top, adding several more points. So a nightly or weekly rental of a Miami condo is squarely taxable, while a lease longer than six months generally is not. The owner is responsible for registering for a sales-tax certificate, collecting the tax from guests, and remitting it on the state and county schedules, and doing all three is what an audit checks.

The reason Florida audits this so actively ties back to the no-income-tax point. Because the state raises no revenue from personal income tax, sales and use tax is a much larger share of how Florida funds itself, so its enforcement of sales tax is correspondingly serious, and short-term rentals are a visible, growing category the state watches. The common failure is the platform assumption. Owners hear that Airbnb or a similar platform collects and remits taxes and conclude they have nothing to do, but platform coverage is uneven, and a platform may remit the state sales tax while leaving the county tourist tax unfiled, or handle neither for certain booking types. Every gap is the owner’s liability, and the county tourist tax in particular is frequently the piece left unfiled in the owner’s own name.

The exposure compounds because an audit looks back over multiple years and adds penalty and interest to the unpaid tax. An owner who operated for two or three years assuming the platform covered everything can face an assessment covering all of those years at once, which turns a few thousand dollars of annual tax into a five-figure bill.

Here is a worked example. Suppose you ran a Miami Beach condo as a short-term rental for two years, collecting about $80,000 a year in guest room charges, and you never registered for a sales-tax certificate because you assumed the booking platform handled the taxes. It turns out the platform remitted the 6 percent state sales tax but never the Miami-Dade tourist development tax. At roughly 6 percent, that county bed tax runs about $4,800 a year, so across two years the state can assess close to $9,600 of unremitted tourist tax, plus penalty and interest, all built from a tax you were supposed to collect from your guests and never did. A real estate investor CPA gets you registered from the start, sets up collection so guests are charged the full tax on the nightly rate, reconciles exactly what each platform remitted against what was due, and if an audit is already underway, responds to the Florida Department of Revenue with organized records and negotiates the assessment down where the facts allow, all managed through your tax compliance work so a state audit finds nothing missing.

A full examination of your rentals is a bigger event than a matching notice, because the IRS is looking at the whole rental activity rather than a single mismatched number, but the way through it is the same, answer each question with records and the correct law, on the agency’s timeline, without volunteering more than is asked. When an examination opens, the IRS identifies the years and issues it wants to review, and for a landlord those issues almost always cluster around the same handful of areas we prepared for when the return was filed, so a well-documented return is already most of the defense. The IRS describes the process in its overview of IRS audits, and the representation is handled through a signed authorization so the examiner deals with us rather than contacting you directly. One thing worth saying up front is that this is a federal examination only, because Florida has no state income tax, so there is no parallel state audit of the same rental income running alongside it, which is a real simplification compared with a state like California.

The first area is income completeness. The examiner will test whether all rent was reported, comparing bank deposits, leases, and any 1099s against your Schedule E. This is where clean bookkeeping pays off, because a bank deposit that looks like unreported rent is often a security deposit, a loan draw, or a transfer between your own accounts, and the answer is a record that shows what each deposit was. Without that record, every unexplained deposit is presumed to be income, and you carry the burden of proving otherwise. For a Miami short-term rental operator, this is also where platform payouts have to be reconciled, so the deposits from a booking platform tie to gross bookings net of fees and remitted taxes.

The second area is deductions. The examiner will ask for support for the larger expense lines, repairs versus improvements, travel, management fees, and especially depreciation. The repair-versus-improvement line matters because a repair is deducted now while an improvement must be capitalized and depreciated, and misclassifying improvements as repairs is a common adjustment. We keep invoices and a fixed-asset schedule that draws the line clearly, and where a cost is genuinely a repair we keep the description and photos that show it restored the property rather than bettered it.

The third area, and the highest-stakes one, is the passive loss and real estate professional question under IRS Publication 925. If you used rental losses against non-passive income, the examiner will ask for the hour logs and material-participation evidence proving the status, which is why the contemporaneous log is the single most important document in a rental audit. If you did not claim the status and instead relied on the $25,000 active-participation allowance, the examiner will still confirm your income was below the phaseout and that you made real management decisions.

Here is a worked example of how preparation changes the outcome. Suppose your rentals are examined for a year in which you deducted a $60,000 loss against wage income under real estate professional status, took $38,000 of depreciation, and expensed a $12,000 roof job as a repair. Three adjustments are on the table. For the $60,000 loss, we present the contemporaneous hour log showing more than 750 hours, and the loss stands. For the $38,000 depreciation, we provide the schedule and any cost segregation report, and it holds. For the $12,000 roof, the honest answer is that a full roof replacement is usually an improvement, so we may concede that it should be capitalized and depreciated rather than expensed, which trades a current deduction for future ones and limits the adjustment to timing rather than a total loss of the deduction. Conceding the weak point while defending the strong ones with records is what keeps an audit contained, and because there is no Florida income tax, the entire result is federal with no state consequences to reconcile afterward, all coordinated through our tax strategy consulting.
