If you earn income outside of PAYE, there is a strong chance this will apply to you. When it applies depends on your qualifying income at the end of each tax year:
• MTD applies from April 2026, if your income is over £50,000 in the 2024 to 2025 tax year
• MTD applies from April 2027, if your income is over £30,000 in the 2025 to 2026 tax year
• MTD applies from April 2028, if your income is over £20,000 in the 2026 to 2027 tax year
For MTD purposes, income is your total sales or turnover, not your profit after expenses are taken into account.
These thresholds mean many more business owners and landlords will be brought into MTD over the next few years.

Under MTD, you will no longer file an annual Self Assessment tax return. Instead, reporting becomes a regular, digital process throughout the year.
You will need to:
• Keep digital records of your income and expenses using MTD compatible software such as Xero
• Submit quarterly updates to HMRC summarising your income and expenses, with self employed income, UK property income and overseas property income each needing a separate update
• Submit a final year-end declaration at the end of the tax year to confirm your total income and tax position, this includes any additional income and replaces the current year end Self Assessment tax return
You can choose to keep your records on a spreadsheet. If you do, you will need HMRC approved bridging software to submit your updates.
is a Paragraph Font
Quarterly updates are submitted to HMRC in line with tax quarter dates. Each submission is cumulative from the start of the tax year, allowing adjustments to earlier figures to be made.
An election can be made to use calendar quarters instead of tax quarters.
The final year-end declaration is prepared to generate your tax liability and replaces the annual Self Assessment Tax Return currently used. This Final Declaration is due by the 31st of January following the end of the tax year.
In line with current requirements, any tax due is payable by the 31st January following the end of the tax year, not quarterly. HMRC have offered assurance this will not change.

Your obligation to join MTD is based on your income in previous tax years. If your income drops below the threshold, you may be able to leave the scheme, but specific rules apply.
If you are already using digital software, you may be mostly set up. If you currently use spreadsheets or manual records, you may need to adapt your system to ensure it meets MTD requirements.
Initially, there may be some changes as you get set up. With the right systems in place, it quickly becomes part of your regular routine, makes year end much easier, and helps you feel more in control of your numbers.
No, your tax is still due by 31 January following the end of the tax year. Quarterly updates are for reporting purposes only, not payments.
If you do not follow the MTD requirements, you will face penalties from HMRC for late submissions or failing to keep digital records. More importantly, leaving it too late can lead to unnecessary stress and rushed, inaccurate reporting.
If you are using tax year quarters, your first quarterly update will cover the period from 6 April to 5 July and is due by 7 August.
Future quarters follow the same pattern:
• 6 April to 5 July, due by 7 August
• 6 July to 5 October, due by 7 November
• 6 October to 5 January, due by 7 February
• 6 January to 5 April, due by 7 May
It is important to be set up in advance so you are ready to report from day one.
