Tax professionals who build tax data
US Tax Lab is a team of working tax professionals across the US.
What we do
We prepare returns for taxpayers who do not exist, so that AI teams have something correct to train on and to grade against.
Each case is written around a real kind of problem, prepared in professional tax software, and reviewed in two layers before it leaves us.
Who we are
16 preparers, 4 reviewers and 2 people on quality assurance. We are tax preparers and bookkeepers, not a CPA firm.
We adhere entirely to Section 7216 and never reuse any client data. How we handle data
