Does Making Tax Digital apply to me?
If you are a sole trader or landlord and your self-employment and property income before expenses was over £50,000 in 2024 to 2025, you should have started on 6 April 2026. From 6 April 2027 it applies over £30,000, and from 6 April 2028 over £20,000.
When are Making Tax Digital updates due?
Quarterly updates are due by 7 August, 7 November, 7 February and 7 May. Each covers the tax year so far, from 6 April to the end of the update period.

Yes, if you owe less than £3,000, already pay tax through PAYE, and HMRC receives your online return by 30 December 2026 or your paper return by 31 October 2026.
What are payments on account?
Two advance payments towards your next Self Assessment bill, each usually half of last year's tax, due by midnight on 31 January and 31 July. You do not have to make them if last year's bill was under £1,000, or if you paid more than 80% of your tax outside Self Assessment.
