Form 26AS vs AIS vs TIS: What Each One Actually Shows, How to Fix Mismatches, and the Form 168 Renaming from 1 April 2026
Form 26AS shows tax credits: TDS, TCS, advance/SAT, refunds. AIS shows the full picture: every transaction the department knows. TIS aggregates AIS for ITR prefill. From AY 2027-28 (tax year 2026-27), Form 26AS becomes Form 168 under IT Act 2025 Sec 510 + Rule 245 IT Rules 2026.

This is the byline for articles produced by TaxSocial's own editorial desk rather than by an individual contributor. Every article under this name is written from the primary source — the Act, the rules made under it, the gazette notification, the circular or the judgment — and is checked against that source before it is published. Articles carry the date they were published and are updated when the law moves. How we work, and how to report an error, is set out on the Editorial Team page.
