## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability taxpulse-us-state-income-tax-answers-ca-ny-3d7c458e
```

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?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
