Automatic exemptions
If your qualifying income is at or below the threshold, MTD for Income Tax does not apply. HMRC has also listed some specific groups that are exempt automatically. Check GOV.UK for the current list.
Digital exclusion
You can apply for an exemption if it is not reasonably practical for you to use digital tools, for example because of age, disability, remote location without internet, or religious beliefs. Apply by contacting HMRC.
Not having time is not an exemption
Being busy or not liking computers does not qualify. A phone based tool like Fixxa that works by voice or WhatsApp is designed for exactly that situation.
