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 response containing a direct answer to the state tax question, grounded in specific statutory citations (e.g. California R&TC sections, FTB guidance, OTA rulings, or New York Tax Law / 20 NYCRR / DTF publications), with machine-verified references that a CPA can independently check. Covers CA static two-era conformity, NOL suspension, and NY rolling conformity with OBBBA decoupling, convenience rule, statutory residency, and resident-credit trap rules.
Example use cases
Example prompt
“Can you look up how California handles NOL suspension under the R&TC — I need the actual code sections and FTB guidance a CPA can verify, not a general summary?”
Technical details
Endpoint
GEThttps://taxpulse.theaslangroupllc.com/api/tax/state?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need citation-locked, statute-grounded answers for California or New York state income tax questions — especially when a CPA, tax attorney, or compliance professional needs to verify the underlying authority. Prefer this over general LLM tax knowledge when statutory accuracy and verifiable citations matter. Not suitable for federal tax questions, states outside CA/NY (until more corpora ship), or situations requiring licensed tax advice.
Side effects
- Question relates to a state not yet covered (not CA or NY) — endpoint returns out-of-scope or unsupported state error
- Ambiguous question lacking sufficient specificity — may return a clarification request or broad answer
- Corpus not yet updated for very recent legislative changes — answer may reflect prior law with caveat
- Rate limit or payment failure for x402 micropayment — returns 402 Payment Required
- Malformed query parameters — returns 400 Bad Request
