What the Petition Asks For
The parliamentary petition closes on 19 November 2026. It asks HMRC to move the quarterly update deadline to 3 months after each quarter ends, so taxpayers and agents have more time to send accurate figures.
The petition argues that the current window puts people under pressure, so they rely more on estimates and the risk of errors and incomplete records goes up. It points to HMRC extending the Capital Gains Tax reporting deadline for UK property from 30 days to 60 days as proof that the rules can be made more flexible.
When the source article was published, the petition had 1,000 signatures [Editor Note: Unverified figure - check against HMRC guidance]. The government responds to petitions that reach 10,000 signatures, and petitions with 100,000 signatures are considered for debate in Parliament. Neither outcome guarantees a change in the rules.
It also helps to know that a quarterly update is a running total, not a tax bill. Our article on whether HMRC calculates your tax from quarterly updates explains how the final figure is worked out.
