The STR Tax Strategy Playbook
How short-term rentals are taxed, start to finish: the classification gate, material participation, how income is reported, depreciation, and the documentation that makes it defensible.

Start with the flagship above — everything else in Tax Strategy supports it.
The guides, in order
In dependency order — Classification first. Everything else follows.
How an STR Is Classified for Tax
The gate that decides which rules apply — average stay, Schedule E vs. C.
Material Participation & §469
Why rental losses are trapped, and what makes STR losses non-passive.
How STR Income Is Reported
Which schedule, which forms, the 1099-K, and estimated taxes.
Depreciation for Short-Term Rentals
27.5 vs 39 years, cost segregation, and bonus depreciation.
Documentation & Substantiation
The records that support each position — and how to keep them.
When there's a real choice
Judgment calls, not how-tos — each weighs the options for your situation.
