Income-tax computation software for CA firms

It is a per-client income-tax computation engine built for CA firms. For each client and assessment year you build a computation that takes income head by head, applies depreciation, capital gains, Chapter VI-A deductions and loss set-off, computes tax under both regimes with surcharge, cess and the Section 87A rebate, checks AMT/MAT where relevant, and arrives at the tax liability — with an ITR form recommendation at the end.

Yes. The engine computes the liability under both the old and new regimes for the same client and surfaces the difference, so you advise on the regime that actually costs your client less for that year rather than guessing. The slab structure, the Section 87A rebate, the standard deduction and the cess used in that computation are pinned to a dated, source-cited rate table — not typed in by hand.

The computation walks the standard heads and the adjustments that sit under them — business and profession with a depreciation block schedule, capital gains, and Chapter VI-A deductions — and applies loss set-off and carry-forward across years. Surcharge and the 4% Health & Education Cess are applied on top, and the Section 87A rebate is granted where the client is eligible.

Yes. For eligible clients the engine supports presumptive computation under Sections 44AD and 44ADA, so small businesses and professionals on the presumptive scheme are computed on the correct presumptive basis rather than forced through a full books-of-account computation.

The engine evaluates Alternate Minimum Tax and Minimum Alternate Tax where they apply, so a computation that would otherwise understate the liability for a client claiming certain deductions is checked against the minimum-tax floor. The rates used are read from the rate table, not hardcoded into the calculation.

Yes. Based on the entity type and the composition of income in the computation, the engine recommends the appropriate ITR form across ITR-1 to ITR-6, so the preparer starts the return on the right form instead of working it out manually.

Yes. Beyond the gross tax liability, you can capture prepaid taxes — TDS, advance tax and self-assessment tax — and the engine nets them to arrive at the balance payable or refundable, and estimates interest under Sections 234A, 234B and 234C where a date is supplied. The rounding follows the Income-tax Act conventions so the figures match an official computation.

Each computation moves through a lifecycle: draft while you build and recompute it, attested once a CA signs off, and locked to freeze it as the filed position. The lifecycle prevents a signed-off computation from being silently changed, which matters when the computation is the basis of a filed return.

Yes. ReadyBooks generates an income-tax computation PDF — the computation sheet a CA shares with the client and keeps on file — from the same engine that did the math, so the document and the working never diverge.

From a single, dated, source-cited rate table inside ReadyBooks that pins each figure — slabs, surcharge, rebate, cess, depreciation and presumptive rates — to its Finance Act or notification, with a verification date and a freshness check that flags the table for re-verification each Union Budget. The marketing figures shown on this page are read from that same table, not retyped.
