Take a filed return apart and check it

A new client hands you the return filed for them last year. Before you sign anything for the year after, it is worth knowing whether that one was computed correctly. Upload the JSON and find out.

Verify a filed return

How it works

The filed CBDT JSON is read back into its schedule-level inputs, those inputs are run through our computation engine, and the result is compared against the values that were actually filed. What comes back is a table, one row per field:

the schedule the field belongs to,
the value in the filed return,
the value our engine computes,
the variance between them, and
a severity — a rounding difference is not a mistake, and is not reported as one.

Above the table is the count of matches, the count of mismatches and the pass rate for the return.

Supported forms

ITR-1, ITR-2 and ITR-4, for AY 2025-26 and AY 2026-27.

What it is not

It is not an opinion and it is not a certificate. It is an independent second computation of the same return, which is the thing a single piece of software can honestly offer. What you do with a variance is professional judgement.

Questions

What does the reverse audit compare?

The values in a filed ITR JSON against what our engine computes from the same inputs, field by field, with the variance and a severity on each row and a pass rate for the return as a whole.

Which forms does it support?

ITR-1, ITR-2 and ITR-4, for AY 2025-26 and AY 2026-27.

Is it useful on a return we filed ourselves?

That is the main use. Running it over a return filed from another software, or filed last year by the client's previous CA, is the fastest read on whether it was computed correctly — before you take responsibility for the year after it.

Does a variance mean the filed return was wrong?

Not by itself. A rounding-level difference is flagged as rounding. What the report gives you is the list of places worth looking at, ranked, with the arithmetic shown on both sides.
