MTD income tax: delays in changing VAT periods

Author: ICAEW Insights

Published: 05 Mar 2026

MTD for income tax starts in April - are your clients ready?

From April individuals with combined gross income from sole trades or property over £50,000 must keep digital accounting records and submit quarterly updates to HMRC. 

Businesses and agents who are considering changing VAT accounting periods to align with Making Tax Digital (MTD) for income tax should be aware that HMRC may take longer than normal to approve the change.

Under MTD for income tax, which is due to start for many sole traders and landlords from April 2026, the taxpayer must submit quarterly updates to HMRC. For 2026/27, the quarters end on:

Default Election for calendar quarters*
5 July 2026   30 June 2026
5 October 2026  30 September 2026
5 January 2027  31 December 2026
5 April 2027  31 March 2027
*Quarters end on 5 July, and so on, unless an election is made to use calendar quarters, in which case the quarters end on 30 June, and so on. 

If the taxpayer is VAT registered and is on VAT ‘stagger’ two or three, as explained in the table below, they may wish to consider aligning their VAT accounting periods  with the MTD for income tax quarters.  The VAT stagger periods are:

  Quarter ends
Stagger one March, June, September, December
Stagger two April, July, October, January
Stagger three May, August, November, February

The taxpayer can make the request through their VAT online account or, if they have an agent, their agent can do it on their behalf through their agent services account. This is explained in more detail in an earlier article

This could bring administrative benefits, including from aligning filing deadlines, but it is important that all implications are considered before requesting a change to the VAT stagger. For example, the timing of the application can affect the number of returns that will be due before the change takes effect. Taxpayers should discuss this with their agent, if they have one, before taking any action. MTD for income tax is likely to have a significant impact on agents’ workloads and changes to staggers may add to these pressures in some circumstances. 

ICAEW members have reported that HMRC is now taking longer to approve changes in VAT accounting periods, with delays of up to six weeks in some cases. Taxpayers and their agents should consider the implications of this when requesting a change to the VAT stagger.
