Making Tax Digital (MTD) for Income Tax is now one of the biggest changes to hit UK landlords in a generation. From 6 April 2026, if your qualifying income from property and self-employment exceeds £50,000 per year, the way you report rental income to HMRC has fundamentally changed.
This guide explains exactly what MTD means for landlords, who it affects and when, what you must do to comply, and how to avoid costly penalties.
What Is Making Tax Digital for Landlords?
Making Tax Digital for Income Tax Self Assessment (MTD for ITSA) is a government initiative to modernise the UK tax system by replacing the traditional once-a-year Self Assessment return with digital record keeping and quarterly reporting.[^3][^4]
Instead of compiling a year’s worth of rental income and expenses every January, you now maintain digital records throughout the year and send HMRC summary updates every three months through HMRC-compatible software. You still submit a final declaration once a year, just as before. The key difference is that HMRC receives regular updates on your rental activity rather than waiting for one annual return.
Who Does MTD Apply To?
MTD for Income Tax applies to individual landlords registered for Self Assessment who receive rental income from UK or foreign properties. Whether you need to comply, and when, depends on your qualifying income.
Qualifying income means your total gross income from both property rentals and self-employment, before deducting any expenses. If you are purely a landlord with no self-employment income, it is simply your total rental income across all properties.
MTD is being rolled out in three phases:
| Phase | Start Date | Qualifying Income Threshold | Based On |
|---|---|---|---|
| Phase 1 | 6 April 2026 | Over £50,000 | 2024/25 tax return |
| Phase 2 | 6 April 2027 | Over £30,000 | 2025/26 tax return |
| Phase 3 | 6 April 2028 | Over £20,000 | 2026/27 tax return |
Limited company landlords are not affected by MTD for Income Tax and will continue paying Corporation Tax in the usual way.
MTD vs Traditional Self Assessment
Understanding how MTD differs from the existing system helps landlords prepare for the change ahead.
| Aspect | Traditional Self Assessment | Making Tax Digital |
|---|---|---|
| Reporting frequency | Once annually | Four quarterly updates plus annual final declaration |
| Submission deadlines | 31 January (online) | 7 Aug, 7 Nov, 7 Feb, 7 May quarterly; 31 January annually |
| Record-keeping format | Paper acceptable | Digital records mandatory |
| Software requirement | Optional | MTD-compatible software required |
| Information submitted | Complete annual return in one go | Summary updates quarterly, then final declaration |
Key MTD Compliance Dates for Landlords
Mark these dates in your calendar. The first quarterly deadline of 7 August 2026 covers the period from 6 April to 5 July 2026.[^6][^7]
| Date | Requirement |
|---|---|
| 5 April 2026 | Registration deadline if 2024/25 income exceeded £50,000 |
| 6 April 2026 | Digital record-keeping becomes mandatory |
| 7 August 2026 | First quarterly update deadline (Q1: 6 April to 5 July 2026) |
| 7 November 2026 | Second quarterly update deadline (Q2: 6 July to 5 October 2026) |
| 7 February 2027 | Third quarterly update deadline (Q3: 6 October to 5 January 2027) |
| 7 May 2027 | Fourth quarterly update deadline (Q4: 6 January to 5 April 2027) |
| 31 January 2027 | Final Self Assessment return for 2025/26 (traditional format, last time) |
| 31 January 2028 | First MTD final declaration due via software (for 2026/27 tax year) |
What Records Must You Keep?
Under MTD, landlords must maintain digital records of every rental income transaction and allowable expense. For each transaction, you must record the date, the amount, and the expense category.
You must also continue keeping supporting documentation such as receipts, invoices, bank statements, and tenancy agreements, exactly as you would under traditional Self Assessment. MTD adds a digital reporting layer on top; it does not remove the need for underlying evidence.
If your letting agent sends you net rental income after deducting their fees, you must obtain the gross income figure and record income and expenses separately. Net figures do not meet MTD requirements.
Digital records must be stored for at least five years after the 31 January submission deadline, which is the same retention period as Self Assessment.
How Quarterly Updates Work
Every three months, you submit a summary of your rental income and expenses to HMRC through your MTD-compatible software. The software totals your digital records by category and sends them directly to HMRC. These updates are informational summaries, not tax calculations, and no payment is triggered when you submit them.
You can choose between two update period types. Standard update periods align with the tax year (6 April to 5 April). Calendar update periods end on the last day of each month. The submission deadlines of 7 August, 7 November, 7 February, and 7 May remain the same for both options.
If a property is vacant or undergoing refurbishment, you must still submit a quarterly update confirming zero income and zero expenses for that period.
The Final Declaration
After your fourth quarterly update, your software displays your total rental income and expenses for the full tax year. Before submitting your final declaration, you must make any necessary adjustments, claim relevant reliefs and allowances such as capital allowances or Rent-a-Room relief, and add all other income sources including dividends, savings interest, and capital gains.
HMRC will pre-populate certain information automatically, including employment income, state pension, and other PAYE data. Once you have reviewed everything and confirmed it is accurate, your software submits the final declaration directly to HMRC. Payment remains due by 31 January.
Choosing MTD-Compatible Software
HMRC does not provide its own software, so landlords must use an authorised third-party product that can maintain digital records, submit quarterly updates, and file the final declaration.
There are two main types of MTD software. Full accounting software such as Xero, QuickBooks, or FreeAgent handles everything from record-keeping to submission in one product. Bridging software connects to existing spreadsheets or property management systems and submits the data to HMRC on your behalf. Landlord-specific options include Landlord Studio, Landlord Vision, and other property management platforms with built-in MTD integration.
If you work with an accountant or tax agent, they will need agent authorisation through your Government Gateway account to submit quarterly updates and access your MTD records on your behalf.
Penalties for Non-Compliance
MTD uses a points-based system for late submissions and tiered penalties for late payments.
Each missed quarterly update or final declaration deadline earns one penalty point. When you accumulate four points, HMRC charges a £200 financial penalty. Every additional missed deadline after that costs another £200 until the points are reset.
For late payments, a penalty of 3% of the outstanding tax applies if unpaid 15 days after the due date, with a further 3% penalty if still unpaid by day 30. From April 2027, both rates rise to 4%. A daily penalty of 10% per year accrues on any amount unpaid beyond 30 days.
Grace period for 2026/27: No penalty points are issued for late quarterly updates in the first year of MTD (2026/27). However, this protection does not apply to the final declaration due on 31 January 2028, which carries full penalties from the outset.
Who Is Exempt from MTD?
Not all landlords must comply. You are automatically exempt if your qualifying income is £20,000 or below, if you are a trustee, a personal representative of a deceased estate, a Lloyd’s underwriting member, or a non-resident company.
You can apply for an exemption if it is not reasonably practical for you to use digital software due to age, disability, remote location without internet access, or religious beliefs incompatible with electronic communications. HMRC considers all applications on a case-by-case basis.
How to Register for MTD
Follow these steps to sign up before your mandatory start date:
- Log in to your Government Gateway account using the same credentials you use for Self Assessment.
- Navigate to the MTD for Income Tax section and confirm your qualifying income exceeds the relevant threshold.
- If already registered for Self Assessment, your existing Unique Taxpayer Reference will link automatically.
- Choose your MTD-compatible software and generate the credentials that allow it to connect to HMRC systems and submit on your behalf.
