How this service works
US state income-tax answers grounded in the actual state code with machine-verified citations a CPA can check. California (R&TC/FTB/OTA, static two-era conformity, NOL suspension) and New York (Tax Law/20 NYCRR/DTF/Tribunal, rolling conformity + OBBBA decoupling, convenience rule, statutory residency, resident-credit trap). Citation-locked state tax intelligence, not advice. More states as corpora ship.
Output
A structured answer to a state income tax question anchored to specific statutory provisions — e.g. California R&TC sections, FTB guidance, OTA rulings, or New York Tax Law sections, 20 NYCRR regulations, and DTF/Tribunal decisions. Includes citations a CPA or attorney can independently verify, covering topics like conformity periods, NOL treatment, residency rules, convenience rule, and resident credit mechanics.
Example use cases
Example prompt
“Can you look up the California state income tax rules on NOL suspension under the Revenue and Tax Code — I need the actual statutory citations my CPA can verify, not just a summary?”
Technical details
Endpoint
GEThttps://taxpulse-phi.vercel.app/api/tax/stateWhen to prefer
Choose this endpoint when you need authoritative, citation-backed answers to California or New York state income tax questions — especially where a CPA, attorney, or auditor needs to verify the source statute. Prefer this over general LLM answers when statutory precision matters: NOL rules, conformity questions, residency determinations, or decoupling from federal law. Not suitable for states other than CA and NY, or for non-income tax topics like sales tax or property tax.
Side effects
- State not yet supported (only CA and NY available) — returns error or empty result
- Ambiguous or too-broad question may yield incomplete citation coverage
- Questions outside income tax scope (e.g. sales tax, property tax) may not be answered
- Rate limit or payment failure returns 402 or 429 error
- Corpus not yet updated for very recent legislative changes
