Making Tax Digital for Income Tax (MTD ITSA) — What Directors Need to Know

MTD ITSA is being phased in from April 2026. Directors with self-employment or property income above £50,000 are affected first. Here's what changes.

Reviewed by D. Cann · Principal, Apex Assets Group
  • MTD ITSA from April 2026: self-employment or property income above £50,000
  • From April 2027: threshold drops to £30,000
  • Dividends are investment income — they do NOT count toward MTD ITSA thresholds
  • Most sole directors with only salary and dividends are not affected
  • Quarterly updates are reporting obligations only — tax is still paid annually

What is MTD ITSA?

Making Tax Digital for Income Tax Self Assessment (MTD ITSA) is a fundamental change to how self-employed individuals and landlords report income to HMRC. It replaces the single annual Self Assessment return with:

  1. Four quarterly updates per tax year — reporting income and expenses for that quarter
  2. One final declaration at the end of the tax year — replacing the SA return, adjusting for any reliefs and calculating the final tax liability

Tax is still calculated and paid annually — the quarterly updates are digital reporting obligations, not quarterly tax payments.

Who is affected and when

PhaseStart dateWho is in scope
Phase 1April 2026Self-employed individuals and landlords with total qualifying income over £50,000
Phase 2April 2027Those with qualifying income over £30,000
Phase 3April 2028 (announced, not yet legislated)Those with qualifying income over £20,000

Qualifying income for MTD ITSA means gross income from self-employment and/or property. The threshold applies to the combination of both sources — not each separately.

Are you affected as a director?

This is the most important question, and the answer for most sole directors is: probably not.

Income typeCounts toward MTD ITSA threshold?
Director salary from your companyNo — employment income
Dividends from your companyNo — investment/savings income
Self-employment income (sole trader work)Yes
Property rental income (gross)Yes
Interest incomeNo — savings income

A director who takes only salary and dividends from their limited company, with no additional self-employment or rental income, is not in scope for MTD ITSA at any threshold — regardless of how large those salary and dividend amounts are.

When directors ARE affected: If you have self-employment income alongside your directorship (e.g., you also do freelance work in your own name), or you own rental property, those income streams count. If gross self-employment + property income exceeds £50,000 from April 2026, you are in scope and must use MTD-compatible software and file quarterly updates.

What MTD ITSA requires in practice

If you are in scope, here is what changes:

Old processNew MTD ITSA process
One Self Assessment return per year (by 31 January)Four quarterly updates + one final declaration
Can file on paper or via HMRC portalMust use MTD-compatible software
Annual record review at year-endOngoing digital record-keeping throughout the year
One penalty point system for SANew points-based penalty system for MTD submissions

Quarterly update deadlines

The four quarterly update periods and their filing deadlines:

QuarterPeriodFiling deadline
Q16 April – 5 July5 August
Q26 July – 5 October5 November
Q36 October – 5 January5 February
Q46 January – 5 April5 May
Final declarationFull tax year31 January (following year)

Quarterly updates contain a summary of income and expenses for the period — not a full detailed breakdown. You are correcting and finalising the position with the final declaration.

What the quarterly updates contain

For self-employment income, each quarterly update reports:

  • Total turnover/gross income for the quarter
  • Allowable expenses by category (staff costs, travel, office costs, etc.)
  • The software calculates the estimated profit and estimated tax liability

The quarterly figures are cumulative estimates — they help you track where you are across the year but are not finalised until the year-end declaration.

Compatible software

You must use HMRC-approved MTD ITSA software. As of 2026-27, approved software includes:

  • FreeAgent — adding MTD ITSA capability; good for sole directors
  • Xero — MTD ITSA ready for self-employment and property
  • QuickBooks Self-Employed / QuickBooks Online
  • Sage — MTD ITSA compatible
  • Various specialist bridging / standalone MTD ITSA apps — some specifically for landlords

HMRC maintains a current list of approved software at hmrc.gov.uk. Check before subscribing — the list of fully approved products is still growing.

The new penalty regime for MTD ITSA

MTD ITSA uses a points-based penalty system for late submissions (replacing fixed SA penalties):

  • Each late quarterly update or final declaration earns one penalty point
  • When points reach the threshold (4 for quarterly filers), a £200 financial penalty is charged
  • Further financial penalties apply for each subsequent late submission while at the threshold
  • Points can be cleared if you file on time for a sustained period and outstanding submissions are up to date

This is designed to be more lenient for occasional lateness but progressively harsher for serial offenders.

MTD ITSA vs MTD for VAT: key differences

Who is affectedAll VAT-registered businessesSelf-employed/landlords above income thresholds

Directors with only salary/dividendsNot applicable (unless company is VAT registered)Not affected (unless separate self-employment/property)

Frequently asked questions

Do dividends count as income for MTD ITSA?
No. Dividends are investment income, not self-employment or property income. The MTD ITSA qualifying income threshold applies only to gross self-employment income and/or gross property rental income. A director with only salary and dividends from their limited company is not in scope for MTD ITSA at any threshold level.
What software do I need for MTD ITSA?
You need HMRC-approved MTD ITSA software — a specific approval separate from MTD for VAT approval. FreeAgent, Xero, QuickBooks, and Sage are adding or have added MTD ITSA capability. Check HMRC's approved software list before subscribing, as the list of fully approved products continues to expand ahead of the April 2026 launch.
What happens if I miss a quarterly update?
Late quarterly updates earn penalty points under the new points-based system. Accumulate 4 points (for quarterly filers) and a £200 financial penalty is charged. Further penalties apply for each subsequent late submission while at the threshold. Points can be cleared by filing on time for a sustained period. The first few late submissions may not trigger a financial penalty — but repeated lateness will.
Do I need to pay tax quarterly under MTD ITSA?
No — tax payment remains annual. The quarterly updates are reporting obligations only. Your tax bill is still calculated via the annual final declaration and paid by 31 January following the tax year, exactly as with the current Self Assessment system.
I am in scope for MTD ITSA from April 2026 — what do I need to do now?
Sign up for MTD ITSA with HMRC before your first quarterly deadline (5 August 2026 for Q1 of the 2026-27 year). Choose and set up MTD-compatible software. Ensure your records are kept digitally from 6 April 2026. Your accountant or software provider will guide the sign-up process — most in-scope taxpayers will be contacted by HMRC in advance.
