MTD Quarterly Deadlines for 2026/27

For taxpayers using the standard tax year accounting period, the mtd quarterly update deadlines follow the same dates throughout 2026/27.

Each quarterly update contains cumulative information from the start of the reporting year to the end of that update period. For example, the second update covers the period from 6 April to 5 October, not just the three months after the first update. These dates form the core mtd itsa deadlines for taxpayers who use standard update periods.

Standard vs Calendar Update Periods

MTD for Income Tax lets you use standard tax year periods or calendar periods for your quarterly updates.

Standard Tax Year Update Periods

Standard periods suit taxpayers whose accounting period runs from 6 April to 5 April. The periods run as follows:

• 6 April to 5 July
• 6 April to 5 October
• 6 April to 5 January
• 6 April to 5 April

Each period has the same submission dates shown in the main calendar.

Calendar Update Periods

Taxpayers whose accounting period runs from 1 April to 31 March can consider calendar update periods. These periods run as follows:

• 1 April to 30 June
• 1 April to 30 September
• 1 April to 31 December
• 1 April to 31 March

The submission dates remain 7 August, 7 November, 7 February and 7 May. Taxpayers must select calendar periods for each income source in their software before sending the first quarterly update. They cannot change the update periods for that tax year after submitting a quarterly update.

What Goes Into Each Quarterly Update?

A quarterly update gives HMRC a summary of income and expenses from the taxpayer’s digital records. It does not work as a full tax return.

Depending on the income sources, the records can include:

• Business income
• Business expenses
• Property income
• Property expenses
• Relevant transaction information held in digital records

Compatible software uses these records to produce the figures for submission. Taxpayers do not need to make their year-end tax adjustments before sending a quarterly update.

The quarterly updates HMRC receives therefore give regular information about business and property activity during the tax year. The final tax position comes later through the tax return.

What Happens After the Fourth Quarterly Update?

The fourth update closes the regular reporting cycle on 7 May 2027. Taxpayers then need to complete the end-of-year process and submit their tax return.

The final process allows taxpayers to:

• Make required accounting and tax adjustments
• Claim eligible reliefs and allowances
• Add other income or gains
• Confirm the final figures
• Calculate the Income Tax position
• Submit the tax return

For the 2026/27 tax year, the tax return deadline falls on 31 January 2028. The quarterly updates do not replace this final tax return.

Top Bookkeeping Services can help keep the underlying records organised throughout the year so the final return does not depend on last-minute record gathering.

MTD Software You Need Before the First Deadline

Taxpayers within MTD must use compatible software to create, store and correct digital records and send quarterly updates to HMRC. They also use compatible software to complete the final tax return.

Before the first deadline, taxpayers should:

• Choose MTD compatible software
• Create the required digital records
• Connect the software to HMRC
• Complete the MTD sign-up process
• Confirm the correct income sources
• Set the correct update periods
• Give an accountant or agent access when required

HMRC recognises different software options, including paid software, free options and bridging solutions. Taxpayers should check compatibility before choosing a system.

What Happens If You Miss a 2026/27 Deadline?

HMRC currently states that taxpayers will not receive penalties for missing a quarterly update deadline during the 2026/27 tax year. However, taxpayers still need to maintain digital records and send the required updates.

This does not remove other tax obligations. Late tax return and late payment penalties can still apply under the relevant rules. The tax return and payment deadline remains 31 January after the end of the tax year.

Taxpayers should therefore treat the first year as a preparation period rather than ignoring the reporting dates.

MTD 2026/27 vs 2027/28: What Changes?
