What U.S. Taxes Should Foreign Nationals Understand Before Buying Miami Real Estate?
By Roman Ivanov, REALTOR® at REAL | 786-909-4892 | MiamiFineLiving.net
The U.S. tax system for foreign property owners is more complex than most international buyers expect going in — and the surprises almost always come at the worst possible times: when rental income starts arriving, or when it is time to sell. Understanding your tax obligations before you buy is not optional in Miami FL real estate 2026. Here is the framework every foreign buyer needs to understand.
Annual Property Taxes: The Easy One
Miami-Dade County property taxes apply to all property owners equally — domestic or foreign. There is no distinction based on nationality. Taxes are based on assessed value and are billed annually. Non-homesteaded properties (those not used as a primary residence by a qualifying owner) are assessed at market value with no cap on annual increases. For a $1.5M non-homesteaded property in Miami, expect annual property taxes in the range of $20,000 to $30,000 depending on the municipality. Key Biscayne home values and Coral Gables home values give you a sense of assessed value benchmarks in Miami's top communities.
Federal Income Tax on Rental Income
If you rent your Miami property — even occasionally — the rental income is subject to U.S. federal income tax. Foreign national landlords have two options: elect to have 30 percent of gross rental income withheld at source (the default for non-resident aliens under the tax treaty framework), or elect to treat rental income as effectively connected income (ECI) — filing a U.S. tax return and paying tax on net rental income after deductions for expenses. The ECI election is almost always more favorable because it allows deductions for mortgage interest, property taxes, management fees, insurance, depreciation, and maintenance.
"The rental income tax question is where I always tell buyers: get the U.S. CPA involved before you buy, not after you've been renting for a year without filing. The penalty exposure for unreported rental income is significant, and the fix is usually straightforward — but only if you address it proactively." — Roman Ivanov, REALTOR at REAL
FIRPTA: The Sale Withholding That Catches Sellers Off Guard
FIRPTA — the Foreign Investment in Real Property Tax Act — is one of the most important and least understood tax obligations for international property owners in Miami. When a foreign national sells U.S. real property, the buyer is required to withhold 15 percent of the gross sales price and remit it to the IRS as a tax deposit — regardless of whether the seller actually owes that much in tax. If you sell a $2M property, $300,000 goes to the IRS at closing unless you have applied for a withholding certificate to reduce or eliminate the withholding based on your actual tax liability. This is not a tax on profit — it is a withholding on the gross price, which can create significant cash flow issues if not anticipated.
Estate and Inheritance Tax Exposure
This is the area that catches the most sophisticated international buyers off guard. Non-resident aliens who own U.S. real estate are subject to U.S. estate tax on the full value of the U.S. property at death — with an exemption of only $60,000 (compared to the multi-million-dollar exemption for U.S. citizens and residents). On a $3M property, the potential estate tax exposure for a foreign national owner holding in their personal name is substantial — commonly 40 percent of the value above $60,000. This is a primary driver of why international buyers structure their purchases through LLCs or other entities. Coral Gables properties in the $2M to $4M range and Bay Harbor Islands homes in the same range are precisely the tier where estate tax planning matters most.
Gift Tax and Cross-Border Transfers
Foreign nationals are also subject to U.S. gift tax rules if they transfer U.S.-sited property during their lifetime. Proper ownership structure — established before purchase — can significantly reduce exposure across both estate and gift tax scenarios.
