What changed

The rules just changed.
Most filers haven't caught up.

From April 1, 2025, the personal relief threshold rose to Rs. 1,800,000. The 12% slab disappeared. AIT on interest doubled to 10%. SVAT is being repealed in October. And e-Filing is now mandatory.

How it works

Three steps. About twenty minutes.

01
Upload your statements

Drop your bank PDF, CSV, or OFX. TaxWise extracts and classifies each transaction — salary, interest, dividends, rent — so you're confirming, not typing.

02
We do the math

Our deterministic engine reads the latest tax law from a versioned, audited database. Every calculation traces back to an Inland Revenue Act section.

03
Review and export

See your final tax and cage-by-cage schedules. Export when ready. You submit through the IRD e-Filing portal — filing is your responsibility.

An AI that won't
make up tax law.

Most AI assistants hallucinate. Ours can't. The TaxWise AI is wired into our deterministic calculation engine: it can query the engine, but it never invents numbers, citations, or rules. Ask "Show me what I owe if I add Rs. 200,000 of bank interest" and the answer carries a citation back to the Inland Revenue Act.
