ptet_rulesElective pass-through entity tax for one state and tax year: eligibility, who elects, deadline, rate, owner credit or exclusion, estimates, and sunset. Returns not_covered when this server has no file. Informational, not tax advice.
salt_capCompute the federal SALT deduction cap under 26 USC 164(b)(6) and (b)(7) for a tax year, filing status, and modified adjusted gross income. Returns the cap and the steps, not the deduction. Years before 2018 are not_covered. MAGI is used to compute and is not written to the usage log.
bonus_conformityWhether a state conforms to IRC 168(k) bonus depreciation and IRC 179 for a tax year, its IRC conformity date, and the add-back or subtraction in plain terms. Unverified fields are null. Unknown states and years are not_covered.
coverageList jurisdictions and tax years in this dataset. elective_ptet_2026 counts only 2026 files with an elective PTET. no_elective_ptet_2026 and not_effective_2026 are separate and are not PTET states for 2026.
