What belongs on a white-label client compliance calendar for CA firms (GST, TDS, MCA)

Updated 13 Oct 2026 · Disclosure: the white-label calendar linked below is an Unadhi product (₹999/year).

Short answer: put only the dates small clients ask about, mark extensions in plain words, and put your firm name (and contact line) on the page. Skip niche forms that never apply. A one-pager clients can pin or forward beats a 40-row spreadsheet they ignore.

How to show extensions without confusing anyone

What "white-label" should mean on the page

You can build all of this from the GST portal and CBDT notices. The work is the checking and the formatting, four times a year.

A free national date file you can use today

Unadhi publishes a free national deadline set for Oct 2026–Mar 2027 as .ics and spreadsheet on this guides site (same files many firms import for staff trackers). Pair it with your own reminder rhythm: see the free client deadline reminder system for CA firms.

If you want the branded pack made for your firm

This guide is general information, not tax advice and not an official government publication. Your firm stays responsible for advice to your clients. Dates move when CBIC, CBDT or MCA publish extensions — always re-check the portal before you file.
