Florida does not tax investment income at the state level. Dividends, interest, and capital gains all pass through untouched by the state, because Article VII, Section 5 of the Florida Constitution forbids a personal income tax on individuals.1FindLaw. Florida Constitution 1968 Revision Art. VII, Section 5 You still owe federal tax on every dollar of investment profit, and if your income is high enough, an extra 3.8% federal surtax lands on top. What Florida saves you is the state layer that residents of New York, California, or New Jersey pay on top of the federal bill.
Why the State Takes Nothing
The constitutional ban covers “natural persons,” meaning individual human beings rather than corporations. Because the prohibition is written into the constitution, repealing it would require a voter-approved amendment, not just an act of the legislature. That makes the no-tax status unusually durable as tax policy goes.
The protection applies to every form of personal income regardless of source. Wages, rental income, pension distributions, interest from savings accounts, dividends from a brokerage account, and capital gains from selling stock or real estate are all treated the same way: no state return, no state tax. Florida has no mechanism to track your personal investment earnings because it never asks.
Capital gains receive the same zero-tax treatment. It does not matter whether you held the asset for two weeks or twenty years, or whether the gain is $500 or $5 million. In states that tax capital gains at ordinary income rates, selling a highly appreciated asset can push the combined state-and-federal rate above 50% in extreme cases. In Florida, only the federal layer applies. That difference often shapes decisions about when to rebalance a portfolio, when to retire, and whether to sell investment real estate.
What the Federal Government Still Collects
Living in Florida does not reduce your federal tax bill by a dollar. The IRS taxes investment income the same way regardless of your state. Interest and dividends go on Form 1040, with Schedule B required when taxable interest or ordinary dividends exceed $1,500.2Internal Revenue Service. Publication 550 (2025), Investment Income and Expenses Capital gains and losses go on Schedule D.3Internal Revenue Service. About Schedule D (Form 1040), Capital Gains and Losses
Short-Term vs. Long-Term Capital Gains
How long you hold an asset before selling drives the federal rate. Assets held one year or less produce short-term gains, taxed at ordinary income rates. For 2026, the top ordinary rate is 37%, hitting single filers with taxable income above $640,600 and married couples filing jointly above $768,700.4Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026
Assets held longer than a year qualify for reduced long-term rates of 0%, 15%, or 20%. The 2026 thresholds for single filers:5Internal Revenue Service. Topic No. 409, Capital Gains and Losses
- 0% rate: taxable income up to $49,450
- 15% rate: taxable income from $49,451 to $545,500
- 20% rate: taxable income above $545,500
For married couples filing jointly, the 0% rate runs up to $98,900, the 15% rate extends to $613,700, and 20% applies above that. Most Florida investors with moderate portfolios land in the 15% bracket, which makes holding past the one-year mark substantially more valuable than a quick sale.
Qualified Dividends
Not all dividends are taxed alike. Ordinary dividends get taxed at your regular income rate. Qualified dividends receive the same preferential rates as long-term capital gains. To qualify, the dividend must come from a U.S. corporation or a qualifying foreign corporation, and you must have held the stock for a minimum period around the ex-dividend date. Most dividends from standard brokerage accounts in domestic stocks meet these requirements automatically. Your 1099-DIV breaks out qualified versus ordinary dividends so you can tell which rate applies.
The 3.8% Net Investment Income Tax
Higher-income Florida residents face one more federal layer. A 3.8% net investment income tax applies when modified adjusted gross income exceeds $200,000 for single filers or $250,000 for married couples filing jointly.6Office of the Law Revision Counsel. 26 U.S. Code 1411 – Imposition of Tax The tax hits the lesser of your net investment income or the amount by which your income exceeds the threshold.
Net investment income includes interest, dividends, capital gains, rental income, royalties, and income from passive business activities. It does not include wages, Social Security benefits, or distributions from most retirement accounts like 401(k)s and IRAs.7Internal Revenue Service. Questions and Answers on the Net Investment Income Tax One detail that trips people up: these thresholds are not indexed for inflation. They have not moved since the tax took effect in 2013, so more filers cross them each year through ordinary wage growth and rising asset values.
For a married Florida couple with $300,000 in total income, $80,000 of it from investments, the 3.8% tax applies to the lesser of $80,000 or the $50,000 excess over the $250,000 threshold. That works out to $1,900 on top of the regular federal tax on the same gains and dividends.
Investment Income Earned Through a Business
The constitutional protection applies only to natural persons. Corporations operating in Florida pay a 5.5% corporate income tax on net earnings, and investment income counts toward the taxable base.8The Florida Legislature. Florida Code 220.11 – Tax Imposed Interest on corporate accounts, dividends on corporate holdings, and gains from selling business assets all feed into that calculation. The first $50,000 of net income is exempt, which zeroes out the tax for many smaller corporations.9The Florida Legislature. Florida Code 220.14 – Exemption S corporations generally escape Florida’s corporate tax, and LLC treatment depends on how the entity is classified federally.10Florida Dept. of Revenue. Florida Corporate Income Tax If investment income flows through to you personally, the state protection reasserts itself.
Making the Benefit Stick: Florida Residency
Moving to Florida does not automatically give you the tax benefits. If you are leaving a state with an income tax, that state will want proof you actually left. Residency audits can be aggressive, particularly from New York, New Jersey, and California, which stand to lose significant revenue when a high-earning resident claims to have gone south.
The formal step is filing a Declaration of Domicile with the clerk of the circuit court in your Florida county. Under Florida Statute 222.17, this is a sworn statement confirming that you reside in Florida and intend to maintain it as your permanent home.11The Florida Legislature. Florida Code 222.17 – Manifesting and Evidencing Domicile in Florida If you also keep a home in another state, the declaration must assert that your Florida residence is your predominant and principal home.
Filing the declaration is necessary but not sufficient. In a residency audit, your former state’s tax agency looks at the full picture of your life. Auditors routinely examine cell phone location records, credit card statements, toll pass data, and medical appointment histories to reconstruct where you actually spent your time. The practical standard most high-tax states apply is spending more than 183 days a year in their jurisdiction, but domicile audits go well beyond day-counting. They look at where your family lives, where your doctors and accountants are, where you vote, where your car is registered, and where you attend religious services. Keeping a lightly used apartment in Manhattan while claiming Florida residency is exactly the scenario auditors are trained to challenge.
The strongest position combines the Declaration of Domicile with a Florida driver’s license, Florida voter registration, Florida vehicle titles, and a clear paper trail showing you spend the majority of your time here. Moving your professional and personal relationships to Florida makes the case much harder to contest.
Foreign Accounts Still Have to Be Reported
Florida’s large international population means many residents hold financial accounts or assets abroad. The state does not tax the income, but federal reporting rules apply with steep penalties for noncompliance.
If your foreign financial accounts exceed $10,000 in aggregate value at any point during the year, you must file a Report of Foreign Bank and Financial Accounts (FBAR) on FinCEN Form 114. The requirement applies whether or not the accounts generated taxable income.12Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR)
Separately, if you hold specified foreign financial assets above certain thresholds, you must attach Form 8938 to your federal tax return. For unmarried taxpayers living in the U.S., reporting kicks in when total foreign asset value tops $50,000 on the last day of the tax year or $75,000 at any point during the year. Married couples filing jointly get higher thresholds of $100,000 and $150,000.13Internal Revenue Service. Do I Need to File Form 8938, Statement of Specified Foreign Financial Assets The FBAR and Form 8938 are not interchangeable. You may need to file both.
