See where you actually stand
Type nine figures off a Form 1040 in, or load the sample return, and get your tax position drawn out rather than listed: what the money did on its way to a tax bill, what the year worked out to, and where the planning questions sit. It is free, it runs entirely in your browser, and nothing is uploaded or stored.

It sits on the Tools page, beside the simulations of the individual rules it runs into. Load the sample return and see the shape of it before you put your own figures anywhere.
How the preview works
The return flow map
A sample return drawn as a path rather than a stack of forms: every figure traced back to the document it came from and forward to the line it lands on — including the two places a limitation quietly changed the number.
Trace a sample return →How it works
The nine lines it reads, the three questions it raises, and the things it deliberately cannot tell you.
What it checks →Your data
The preview makes no request that carries your figures. What that means exactly, and the one piece of third-party code involved.
How your return is handled →The underlying tools
The free simulations behind the rules a return runs into — brackets, Social Security inclusion, the tax benefit rule, annuities.
