How And When To Apply
If you think your circumstances might genuinely meet the digitally excluded criteria, apply before you'd be required to start using MTD, not after your deadline has already passed. HMRC has said explicitly that the timing of your application should be based on when you'd actually need to start using Making Tax Digital for Income Tax.
If you've already signed up to MTD and your circumstances later change, you're still legally required to keep using it while HMRC processes your exemption application, which normally takes a few weeks. It's also worth knowing that even if you're already exempt from MTD for VAT, that exemption doesn't automatically transfer. You'll still need to contact HMRC directly by phone or in writing, provide your National Insurance number and VAT registration number, and explain your reason again, so they can confirm the same exemption also applies for Income Tax.
It helps to know where you sit in the wider rollout too. MTD is already mandatory for the £50,000 income group as of 6 April 2026, with the first quarterly update deadline having passed on 7 August 2026, and if you've already made the switch, our article on how to connect Pie to Making Tax Digital covers the setup step by step. The £20,000 threshold group isn't due to get exemption applications open until "summer 2027 onwards", so if that's you, there's no need to act yet, though it's worth bookmarking this page for when the window opens.
