AI Tax Workspace

Calculate, understand, and cross-check before you file

One guided workflow connects tax residency, income documents, deterministic rules, filing guidance, and ITIN support when your case needs it.

01
Residency

Start with tax residency — every downstream rule depends on it

  • Review visa category, U.S. presence days, exempt years, and green card history
  • Determine whether Form 1040-NR is supported before calculating any amount

Six ways nonresident returns go wrong

The tool is designed around the points that most often change the result: residency, source documents, treaty conditions, withholding, and software reconciliation.

Wrong residency status
Starting with the wrong resident or nonresident status changes the return, rate schedule, treaty treatment, and forms that follow.
Unconfirmed OCR values
A scanned box can be misread. Every extracted W-2 or 1042-S value must be confirmed against the original before calculation.
AI-generated tax numbers
Language models can explain rules, but they should never invent tax amounts. Our calculations come only from deterministic code.
Assumed treaty benefits
A passport alone does not create a treaty benefit. Each article, income type, presence limit, and eligibility condition must be tested.
Missed withholding errors
Federal, state, Social Security, and Medicare withholding are different. Failing to separate them can hide an overpayment or a recovery path.
No software cross-check
A final number without a calculation chain is hard to trust. Compare our line-by-line result with OLT or another filing product before submission.
