Model how accelerated depreciation might affect your tax picture

STR Benefit Lab is a scenario planner—not a tax filing tool. Enter your property and income assumptions, compare a baseline to a cost-seg-style allocation, and explore reinvestment and cash-on-cash illustrations with full transparency into methodology.

Explainable outputs

Tooltips and methodology notes tie numbers back to inputs and simplifying assumptions.

Scenario persistence

Save versions when Postgres is configured—clone scenarios and keep an audit trail of recalculations.

Pluggable estimates

Address-based suggestions use a mock service today; swap in a property API without rewriting the UI.

Important

Federal and state tax systems include passive activity rules, at-risk limits, material participation tests, bonus depreciation phase-downs, and state-specific conformity. This app uses a deliberately simple marginal-rate shell so you can stress-test directionally—not replace a CPA engagement.
