MTD for ITSA penalties and how to avoid them

Britain’s push towards Making Tax Digital (MTD) will transform income-tax reporting for sole traders and landlords, with MTD for ITSA penalties for UK sole traders becoming an important compliance consideration. From 6 April 2026, those with qualifying income above £50,000 must keep digital records and submit quarterly updates. Individuals earning over £30,000 join in 2027, followed by those over £20,000 in 2028. To enforce compliance, HMRC has created a points-based penalty regime; understanding MTD for ITSA penalties and how to avoid them is vital for anyone who will come under Making Tax Digital for Income Tax Self-Assessment (ITSA).

A new approach to MTD for ITSA penalties

HMRC has introduced a points-based penalty system for late submissions instead of immediate fines.

• Missed deadlines: Each missed quarterly update or tax return deadline results in one penalty point.
• First year flexibility: There is no financial penalty for late quarterly updates in the first year (2026–27), although points may still be recorded.
• Penalty threshold: Once a taxpayer reaches four penalty points, HMRC issues a £200 fine.
• Further missed deadlines: Every additional missed submission after reaching the threshold results in another £200 penalty.
• Points expiry: If you stay below the four-point threshold, penalty points automatically expire after two years.
• Removing points after the threshold: If four points are reached, they remain until you:
  • Submit all returns on time for 12 months, and
  • Clear any outstanding submissions from the previous 24 months.

Keeping records up to date and meeting submission deadlines is therefore essential to avoid MTD for ITSA penalties and the accumulation of penalty points.

Late payment penalties explained

Late payment penalties are separate from submission penalties and depend on how quickly the outstanding tax is paid.

• First-year grace period: Taxpayers have 30 days after the payment deadline to pay the tax or agree to a payment plan with HMRC.
• Later years: The grace period reduces to 15 days after the first year of the regime.
• No penalty window: There is no penalty if the tax is paid within 15 days of the due date.
• 16–30 days late: A percentage penalty is applied to the outstanding tax.
• More than 30 days late: Additional percentage penalties may apply, along with daily interest on the overdue amount.
• Time to Pay arrangements: Agreeing to a payment plan with HMRC within the grace period can stop further penalties from building up.

Taking action quickly and communicating with HMRC early can help reduce the financial impact of late payments.

Who is affected and why it matters

The penalty regime applies to individuals who file through self-assessment and exceed the qualifying income thresholds for MTD, meaning MTD for ITSA penalties for UK sole traders will become increasingly relevant as the rules take effect. Sole traders, landlords and partnerships (once brought into the system) must maintain separate digital records for each source of income and send individual quarterly updates, making MTD for ITSA penalties for UK landlords an important risk to understand. The rules do not apply to trusts, estates and non‑resident companies. Penalty points accumulate quickly, so robust digital bookkeeping and punctual submissions are essential to avoid fines and reputational damage.

Avoiding penalties: practical steps

Being prepared is the best defence against penalties. Businesses should:

• Adopt MTD‑compatible software and keep digital records up to date.
• Note the quarterly deadlines (7 August, 7 November, 7 February and 7 May) and submit updates promptly.
• Watch your penalty points and tax liabilities through HMRC’s online services; if cash is tight, contact HMRC quickly to arrange a payment plan.
• Check if you qualify for an exemption due to digital exclusion or other specific circumstances.

FAQs

What triggers a penalty under MTD for ITSA? 

You earn a penalty point every time you miss a quarterly update or fail to file your annual tax return by 31 January. There is no penalty for missing quarterly updates in the first year. Four points lead to a £200 fine, and each subsequent missed deadline incurs another £200.

Are there penalties for late payment? 

Yes. You have 30 days (15 days after the first year) to pay or arrange a payment plan. Payments made after that period attract a percentage of the tax owed plus daily interest.

Do VAT points count towards ITSA penalties?

No. Penalty points for MTD for ITSA are separate from those for VAT.

Who must comply with MTD for ITSA? 

Solo traders and landlords whose qualifying income exceeds £50,000 from April 2026, £30,000 from April 2027 or £20,000 from April 2028. Partnerships will join later; trusts and non‑resident companies are excluded.

How can I remove penalty points? 

Points expire automatically after two years if you stay below the threshold. If you reach four points, you must file on time for 12 months and clear any outstanding returns from the previous 24 months to reset.
