Making Tax Digital for Income Tax Self Assessment (MTD for ITSA) is HMRC’s most significant overhaul of personal tax reporting in a generation. From 6 April 2027, it will extend to all landlords and sole traders with qualifying gross income above £30,000, bringing hundreds of thousands more property owners into a new digital reporting regime. If your rental income sits between £30,000 and £50,000, or your rental and self-employment income combined crosses £30,000, the April 2027 deadline applies directly to you and preparation should start now.
What Is MTD for ITSA and How Does It Work?
MTD for ITSA replaces the traditional annual Self Assessment tax return for landlords with a year-round digital reporting system. Instead of filing once a year, landlords must keep digital records using HMRC-recognised software and submit four quarterly updates each tax year, followed by a Final Declaration that closes out the annual tax position.
The system works in three stages. First, you keep running digital records of all rental income and allowable expenses throughout the year using compatible software. Second, you submit quarterly updates to HMRC by the 7th of the month following each quarter end, on 7 August, 7 November, 7 February, and 7 May each year. Third, after your fourth quarterly update, you submit a Final Declaration confirming your total income, any adjustments, and capital gains, replacing the current SA100 return with a January 31 deadline as before.
Who Is Affected from April 2027?
HMRC determines eligibility using your gross qualifying income, not your taxable profit. Qualifying income is the total of your gross rental receipts and gross self-employment turnover before any expenses are deducted.
If your qualifying income on your 2025/26 Self Assessment return, the return covering the tax year ending April 2026, exceeds £30,000, you will be required to join MTD for ITSA from 6 April 2027. Crucially, income from employment, pensions, dividends and savings interest does not count toward the qualifying income threshold. Only rental receipts and self-employment turnover are included.
A landlord receiving £22,000 in rental income who also earns £12,000 from a self-employed trade has qualifying income of £34,000 and falls within scope from April 2027, even though neither income stream on its own crosses the threshold. For jointly owned properties, only each individual owner’s share of the gross income counts toward their own threshold assessment.
The Three-Phase Rollout Timeline
MTD for ITSA is being introduced in three waves:gov+1
- 6 April 2026: Landlords and sole traders with qualifying income above £50,000 (based on the 2024/25 tax return) — already live
- 6 April 2027: Qualifying income above £30,000 (based on the 2025/26 tax return)
- 6 April 2028: Qualifying income above £20,000 (based on the 2026/27 tax return)
Landlords whose income falls below £20,000 remain in the current Self Assessment regime for the foreseeable future.rentalbux+1
Choosing the Right MTD Software
There is no HMRC portal for MTD submissions. Every landlord must use third-party software that connects to HMRC via an API. The software must be capable of maintaining digital records of income and expenses, preparing and submitting quarterly updates, and filing the Final Declaration at year end.
The most widely used full-accounting platforms with MTD for ITSA capability include Xero, QuickBooks Online, FreeAgent, and Sage Business Cloud. Landlord-specific platforms such as Hammock and Landlord Vision offer property-focused features designed around rental income tracking. If you already use spreadsheets, bridging software can connect your existing records to HMRC’s systems without requiring a full switch to cloud accounting.
The right choice depends on the size of your portfolio, whether you also run a self-employed business alongside your property income, and how much time you want to spend on bookkeeping yourself. Landlords with larger or more complex portfolios typically benefit from working with an accountant who manages submissions on their behalf through agent-enabled software.
What Penalties Apply for Non-Compliance?
HMRC operates a points-based penalty system for missed MTD quarterly submissions. Each missed deadline earns one penalty point. Once four points are accumulated, a £200 fixed penalty is triggered, with a further £200 charge for each subsequent missed deadline.
HMRC offered a soft landing during the 2026/27 tax year, meaning no penalty points were issued for missed quarterly deadlines in the first wave. That soft landing does not automatically extend to the 2027/28 tax year covering the second wave of landlords. From April 2027, the full penalty regime applies from the outset for new joiners.
Late payment penalties are separate and apply where tax remains unpaid more than 15 days after the due date. A charge of 3% applies from day 15, rising to a further 3% from day 30, with 10% per annum continuing to accrue daily after that.
HMRC can also impose a penalty of up to £3,000 for failure to keep adequate digital records in any quarterly period.
Steps to Take Before April 2027
With roughly nine months of the 2025/26 tax year remaining when many landlords will begin reviewing their position, there is still sufficient time to prepare properly:
Step 1: Check Your 2025/26 Tax Return Figures
When you file your 2025/26 tax return, review your combined gross rental and self-employment income. If it exceeds £30,000, you fall within scope for the April 2027 MTD for ITSA deadline and must prepare accordingly.
Step 2: Choose and Sign Up to MTD-Compatible Software
Select MTD-compatible software well in advance of the deadline. Starting early gives you time to troubleshoot the platform, build consistent quarterly record-keeping habits, and avoid the last-minute pressure that affected many landlords ahead of the April 2026 rollout.
Step 3: Register With HMRC for MTD for ITSA
HMRC does not enrol landlords automatically. You or your appointed agent must register through the GOV.UK service before your designated start date. Do not leave this until the final weeks before April 2027.
Step 4: Understand How Separate Property Businesses Are Reported
If you own properties across multiple structures, for example properties held in your personal name alongside others held within a partnership, each business may require its own separate quarterly updates. Clarify your reporting obligations early so you are not caught off guard by the volume of submissions required.
How UK Property Tax Accountants Helps with MTD Preparation
At UK Property Tax Accountants, we guide landlords through every step of the MTD for ITSA transition, from assessing whether your income brings you into scope for April 2027, to setting up the right software and managing quarterly submissions on your behalf.
Our team will review your 2025/26 rental and self-employment income to confirm your MTD status, recommend the most suitable software for your portfolio size and complexity, and handle your HMRC registration.
We submit all four quarterly updates and your Final Declaration each year, ensuring deadlines are never missed and penalties are never incurred. Where your income is close to the threshold, we advise on whether any structuring options, such as holding future properties through an SPV limited company rather than personally, could keep you outside the regime. Speak to our team today to make sure April 2027 is not a surprise.
FAQs
1. Does the £30,000 MTD threshold apply to my gross rental income or my profit after expenses?
It applies to your gross rental receipts before any expenses are deducted. The threshold is based on qualifying income, not taxable profit.
2. I earn £18,000 in rent and £15,000 from self-employment. Do I need to join MTD in April 2027?
Yes. Your combined qualifying income is £33,000, which exceeds the £30,000 threshold for April 2027, even though neither income stream on its own crosses it.autoentry+1
3. How do I know if I need to join MTD for ITSA in April 2027?
HMRC assesses eligibility based on the qualifying income shown on your 2025/26 Self Assessment return. If your gross rental and self-employment income combined exceeds £30,000 for that year, you must join from 6 April 2027.gov+1
4. Can I continue using spreadsheets under MTD?
Yes, but only if you use HMRC-recognised bridging software that connects your spreadsheet records to HMRC’s systems. Spreadsheets alone, without the bridging connection, do not satisfy MTD requirements.
5. What are the quarterly submission deadlines for landlords?
Updates are due by 7 August, 7 November, 7 February, and 7 May each year, covering the four quarters of the tax year. A Final Declaration is then due by 31 January following the tax year end.
6. Does MTD apply to properties held in a limited company SPV?
No. MTD for ITSA applies only to personal, unincorporated property income. Rental income received through a limited company is reported through Corporation Tax and is not within the scope of MTD for ITSA.
