Why the IRS Pays Attention to Miami

Miami has become a magnet for wealth. Finance professionals who left New York, tech entrepreneurs from the Bay Area, real estate investors from Latin America, and crypto traders who moved here during the 2020-2021 boom — they all brought complex tax situations with them.

The IRS sees several patterns in South Florida returns that trigger closer review:

• Large cash transactions — Miami’s hospitality, nightlife, and service industries involve substantial cash flow that the IRS watches closely through Currency Transaction Reports and SARs
• International connections — FBAR and FATCA reporting obligations are common for Miami residents with financial accounts in Central and South America, the Caribbean, or Europe
• Real estate at scale — Miami-Dade County’s property market involves foreign investment, 1031 exchanges, and depreciation schedules that the IRS reviews at elevated rates
• Recently relocated high earners — the IRS coordinates with states like New York and California that actively audit people who claim to have moved to Florida

No State Audit — But Don’t Get Comfortable

Florida residents don’t face a state income tax audit. That much is true. There’s no Florida equivalent of the New York DTF or California FTB breathing down your neck over residency questions or business income allocation.

But here’s the catch that trips people up: if you moved to Miami from a state that does have income tax, that state can still audit you. New York’s Department of Taxation and Finance is famous for pursuing former residents who relocated to Florida. They’ll examine whether you truly established Florida domicile or just rented an apartment in Miami while keeping your real life in Manhattan.

California’s FTB does the same thing. If you lived in LA, moved to Miami, but still had California-source income from consulting contracts, production work, or rental properties, the FTB will argue you owe California tax on that income regardless of where you sleep at night.

So while Florida itself won’t audit you, your former state might. And the IRS is always in play.

How a Federal Audit Actually Works

About 75% of all IRS audits are correspondence audits — a letter asking you to verify a specific deduction or explain why a 1099 amount doesn’t match what you reported. You send documentation by mail or fax, and the examiner either accepts it or proposes an adjustment. These are generally straightforward.

Office audits require you to visit the local IRS office with your records. In Miami, that’s the IRS office on North Miami Avenue. The examiner reviews specific items from your return — typically business expenses, rental income, or investment transactions — in a meeting that runs two to four hours.

Field audits are the most intensive. A revenue agent visits your home or business and conducts a deep review over days or weeks. If you’re a business owner in Miami with multiple entities, real estate holdings, or international financial activity, a field audit is the most likely type you’ll encounter.

FBAR and International Reporting Issues

Miami’s international character makes FBAR (FinCEN Form 114) and FATCA (Form 8938) compliance a bigger deal here than in most American cities. If you have foreign financial accounts with an aggregate value exceeding $10,000 at any point during the year, you’re required to file an FBAR. The penalties for failing to file — even unintentionally — start at $10,000 per account per year.

We see this constantly with clients who have family accounts in Colombia, Brazil, Argentina, or the Caribbean. They’ve had these accounts for years, never knew about the reporting requirement, and suddenly face five- or six-figure penalty assessments. The IRS Streamlined Filing Compliance Procedures can help if you qualify, but the window to use that program isn’t guaranteed to stay open forever.

What to Do When You Get the Notice

Read every word of the letter. The notice tells you which tax year, which line items, and what documentation the IRS wants. Don’t call the IRS to “explain” — anything you say can and will be used to expand the scope of the audit.

Gather your records. For Miami taxpayers, the common items under review include:

• Bank statements from both domestic and foreign accounts
• Real estate closing documents, rental agreements, and depreciation schedules
• Business income documentation — 1099s, K-1s, profit and loss statements
• Records establishing Florida domicile (voter registration, driver’s license, homestead exemption filing)
• Documentation for any cryptocurrency transactions reported (or not reported) on the return

Get professional help. A CPA or enrolled agent can represent you before the IRS using Form 2848, which means you don’t have to attend the audit yourself. Given the stakes — especially when international reporting penalties are on the table — this is not the place to cut costs.
