Making Tax Digital for Landlords & Sole Traders

No. The four quarterly submissions are informational updates summarizing your income and expenses to HMRC. Your actual income tax and National Insurance payment deadlines do not change: they remain due by 31 January (balancing payment and first payment on account) and 31 July (second payment on account).

HMRC legislation explicitly defines MTD eligibility by qualifying gross income (total turnover before any expense deductions or finance costs). HMRC does this to standardise entry criteria. A landlord with £60,000 rent and £50,000 mortgage/expenses has a net profit of £10,000, but is mandated immediately under Phase 1.

Quarterly updates do not require complex tax accounting adjustments (such as capital allowances or Section 24 relief). If an omission or minor error occurs, it can be corrected in your next quarterly update or during the Final Declaration at year-end without penalties.

No penalty points apply to late quarterly updates during the transitional 2026/27 tax year. From the following year, each missed quarterly deadline normally generates one point; reaching four points triggers a £200 penalty, plus an additional £200 for each subsequent late quarterly update. Points expire after 24 months of full compliance. Note that quarterly updates remain legally required during 2026/27 even while penalty points are paused.

You can only use spreadsheets if they are digitally linked to an authorized MTD bridging application capable of sending data directly to HMRC's API. Manual re-typing or copy-and-pasting figures into an HMRC web portal is strictly prohibited. For most clients, dedicated software like Xero or QuickBooks is simpler and more reliable.

Each joint owner must assess their individual gross share of the property income. For example, if a property produces £70,000 gross rent and is owned 50/50, each spouse has £35,000 qualifying property income. They would not be mandated in Phase 1 (>£50k), but both would enter MTD under Phase 2 (>£30k from 6 April 2027). If each share were £25,000, they would join under Phase 3 (>£20k from 6 April 2028). Anyone with £20,000 or less is not currently mandated. HMRC also offers simplified quarterly reporting options for joint owners.

HMRC determines your mandate start date based on the gross qualifying income declared on an earlier Self Assessment tax return:

• 2024/25 tax return: Determines if you must start on 6 April 2026 (Phase 1, if gross income exceeds £50,000).
• 2025/26 tax return: Determines if you must start on 6 April 2027 (Phase 2, if gross income exceeds £30,000).
• 2026/27 tax return: Determines if you must start on 6 April 2028 (Phase 3, if gross income exceeds £20,000).

If your gross qualifying turnover remains at or below £20,000, you are not currently mandated to use MTD and continue using standard annual Self Assessment returns, subject to future statutory changes and exemptions.
