State income tax and real estate

State income tax is the layer real estate investors most often underestimate, and it compounds fast for anyone who owns property across state lines. The governing principle is simple and unforgiving: a state taxes income from real estate located within its borders, regardless of where the owner lives. So a Florida resident with a rental in California owes California tax on that California income, even though Florida has no income tax. Add a few out-of-state properties and you have multiple state returns, credit calculations to avoid double taxation, and, if you hold through a passthrough entity, access to one of the more valuable planning moves in current tax law.

Source-based taxation: the property’s state wins

The rule is that real estate income is sourced to where the property sits. Rental income from a building in a given state is that state’s to tax, and so is the capital gain when you sell it. Your state of residence taxes your worldwide income, but the property’s state gets first claim on the income the property generates. This means an out-of-state investor generally must file a nonresident return in each state where they own property, reporting the income sourced there.

To prevent the same income from being taxed twice, your home state typically grants a credit for taxes you paid to other states on that income. The mechanics: you pay the property state as a nonresident, then claim a credit on your resident return for those taxes, so you effectively pay the higher of the two states’ rates, not both stacked. The credit usually works cleanly between two income-tax states, but it breaks down at the edges, which is where investors get surprised.

A state taxes income from real estate located there regardless of where you live, so out-of-state owners file nonresident returns, with a home-state credit generally preventing double taxation.

The no-income-tax-state trap

Here is the edge case that catches investors, and it runs opposite to intuition. Living in a no-income-tax state does not help you on out-of-state property, and can hurt. If you live in Florida, Texas, Nevada, or Washington and own a rental in a high-tax state like California, you pay that state’s full income tax on the property’s income as a nonresident, and your home state has no income tax, so there is no resident return and no credit to offset it. You simply pay the property state’s full rate with no relief.

Contrast a New York resident with the same California property: they pay California, then claim a credit against their New York tax, softening the blow. The Floridian gets no such credit because Florida taxes nothing to credit against. So the after-tax yield on high-tax-state property is actually lower for a no-income-tax-state resident than for a resident of another high-tax state, a genuinely counterintuitive result. Where you live changes the after-tax return on the same out-of-state building.

Living in a no-income-tax state gives no credit to offset tax on out-of-state property, so a Florida resident pays a high-tax state’s full rate with no relief, lowering their after-tax yield.

The SALT cap and the passthrough workaround

The federal deduction for state and local taxes matters here, and it has been in flux. The SALT deduction was capped at $10,000 by the 2017 law; the 2025 tax law raised the cap to $40,000 for 2025 (rising slightly each year), phasing down above $500,000 of income and reverting to $10,000 in 2030. That cap limits how much of your state income and property taxes you can deduct federally.

The powerful workaround, available if you hold real estate through a partnership or S corporation, is the passthrough entity tax, the PTET. More than 30 states now let a passthrough entity elect to pay the owners’ state income tax at the entity level, where it is deducted as an ordinary business expense with no SALT cap, and the owner then claims a state credit or income exclusion for the tax the entity paid. The effect is to convert a capped, often-lost individual SALT deduction into a fully deductible business expense at the entity level. For a real estate investor operating through an LLC taxed as a partnership, a PTET election can restore the federal deduction for state taxes that the cap would otherwise deny, and it remains valuable even with the higher cap, which is why it is worth raising with your advisor for any multi-state passthrough portfolio.

The federal SALT deduction is capped, but a passthrough entity tax election lets your LLC or S corporation pay state tax at the entity level and deduct it uncapped, restoring a federal benefit the cap denies.

The bottom line

• A state taxes income and gain from real estate located there, regardless of where you live.
• Out-of-state owners file nonresident returns, with a home-state credit generally preventing double taxation.
• Living in a no-income-tax state gives no credit, so you pay a high-tax state’s full rate on property there.
• The federal SALT deduction is capped at $40,000 for 2025, phasing down and reverting to $10,000 in 2030.
• A passthrough entity tax election lets an LLC or S corporation deduct state tax uncapped at the entity level.
