A detail that surprises nearly every first time out of state buyer: your federal return and your state return may treat the same depreciation very differently, because states do not uniformly follow federal rules.

What conformity means
States build their income tax systems on top of federal definitions to varying degrees. Some adopt federal rules as they change, some adopt them as of a fixed date, and some adopt them selectively with specific exceptions.
Bonus depreciation is one of the most commonly decoupled items. A state that has decoupled may require you to add back some or all of the federal bonus depreciation deduction for state purposes, then allow depreciation on a different schedule over subsequent years.
The effect is not that the deduction disappears. It is that the timing differs between your federal and state returns, sometimes substantially, which affects the cash benefit in the year you expected it.
Two states can be involved
An out of state purchase potentially involves two state tax systems:
- The state where the property is located, which may require a nonresident return reporting income sourced there.
- Your state of residence, which generally taxes residents on all income, typically with a credit mechanism for taxes paid to other states.
Each has its own conformity rules, its own rates, and its own filing requirements. A resident of a state with no income tax buying in a state that has one faces a different picture than the reverse. See buying an Airbnb out of state.
Out of state purchases raise two tax questions
Where you live and where the property sits both matter. We flag it during acquisition so your CPA can model it before closing.
Apply NowQuestions for your CPA before closing
- Does the property's state conform to federal bonus depreciation, and if not, what is the adjustment?
- Does my resident state conform, and how does it treat income sourced to another state?
- Will I have a nonresident filing obligation, and from what threshold?
- How does the credit for taxes paid to other states work in my situation?
- Does either state impose entity level taxes or fees if I hold the property in an LLC? See holding an STR in an LLC.
- Are there state level lodging or occupancy tax registration requirements separate from income tax?
The practical consequence
None of this changes whether short-term rental investing makes sense. It changes the precision of the model. A buyer expecting a specific first year cash tax benefit should know whether their state will follow the federal treatment, because the difference between the two can be material in the year that matters most.
It also argues for having the conversation before closing rather than in April, which is the same argument that applies to management structure and market selection. See bonus depreciation in 2026 and our partner firm's material on cost segregation studies.

Frequently asked questions
Do states follow federal bonus depreciation rules?
Not uniformly. Some states adopt federal rules as they change, some as of a fixed date, and some selectively with exceptions. Bonus depreciation is among the most commonly decoupled items, which can require adding back some or all of the federal deduction for state purposes.
Do I have to file a tax return in the state where my rental is located?
Frequently yes. A nonresident return reporting income sourced to that state may be required, subject to that state's thresholds. Your resident state generally taxes all income with a credit mechanism for taxes paid elsewhere, and the interaction should be modeled with your CPA.
Does decoupling mean I lose the deduction?
Generally no. It usually means the timing differs between your federal and state returns, with depreciation allowed on a different schedule over subsequent years. The effect is on the cash benefit in the year you expected it rather than on the total deduction.
What should I ask my CPA before an out of state purchase?
Whether the property's state and your resident state conform to federal bonus depreciation, whether you will have a nonresident filing obligation, how the credit for taxes paid to other states applies, whether either state imposes entity level taxes or fees, and what lodging tax registrations are required.
