HMRC has reminded sole traders and landlords earning more than £50,000 that their second Making Tax Digital (MTD) for Income Tax quarterly update must be sent by Saturday 7 November 2026. MTD became compulsory for this group on 6 April 2026, and HMRC says thousands have already sent their first update. In a notice published on 2 November, HMRC explained that a quarterly update is only a short summary of your self-employed (and property) income and expenses, sent through compatible software. It does not work out any tax and you do not pay anything with it. Your overall tax for 2026 to 2027 is worked out later, in your tax return. If you sent your first update in August, you don't need to ring HMRC to check it arrived: you can see your submission history in your HMRC online account or in your software. If you find a mistake in your records, fix it as soon as you can; the correction goes into your next update, so you don't need to resend earlier ones. Because the deadline falls on a Saturday, the Self Assessment helpline will take calls about sending the update on 7 November from 9am to 3pm. The £50,000 level drops to £30,000 from 6 April 2027 and to £20,000 from 6 April 2028.
