How it works

Your agent asks the server for a form's schema and notes, then collects your numbers.
The server validates the entries, computes the arithmetic lines (totals, self-employment tax, taxable income, tax), and returns the computed lines, warnings, and a link.
The link opens here. Your browser fills the official IRS PDF locally and lets you download it.

Privacy by construction

The server keeps nothing: no database, no logs of what you send, no accounts.
Your filled-in values travel in the part of the link after #, which browsers never send to any server.
The PDF is generated on your machine from the blank IRS form.

What it does not do

It does not e-file. Print, sign, and mail the return, or hand the PDF to a preparer.
It does not compute credits, itemized deductions, the qualified business income deduction, or the capital gains worksheet. It tells you when one of those applies.
It is not tax advice. Verify every line against the IRS instructions.
