The way landlords report their rental income to HMRC is undergoing its biggest change in a generation. Making Tax Digital (MTD), the government’s initiative to digitise the UK tax system, is now being extended to Income Tax Self Assessment (ITSA). The days of a single, annual tax return are numbered.
For many landlords, this shift can seem daunting. New rules, new software, and new deadlines can feel like a major administrative burden. However, with a clear understanding of the requirements and a bit of forward planning, the transition can be seamless.
Here are the top five things every landlord needs to know about MTD for ITSA right now.
1. What is MTD and Who Does It Affect?
Making Tax Digital for Income Tax Self Assessment (ITSA) is a new system that requires landlords and self-employed individuals to keep digital records and submit tax updates to HMRC quarterly, rather than just once a year.
The key thing to know is the implementation date and the income threshold that applies to you. MTD for ITSA is being rolled out in phases:
- From April 2026: It becomes mandatory for landlords with a total annual qualifying income (from property and/or self-employment) of over £50,000.
- From April 2027: The rules will be extended to those with a total annual qualifying income of over £30,000.
It’s crucial to understand that this threshold is based on your total gross income or turnover, not your profit. If you have £40,000 in rental income and £15,000 from a freelance side business, your total qualifying income is £55,000, meaning you must comply starting in April 2026.
2. Quarterly Reporting Replaces the Annual Tax Return
This is the most significant change for landlords. The single Self Assessment tax return filed by January 31st will be replaced by a new, more frequent reporting schedule. Under MTD for ITSA, you will be required to make four quarterly submissions plus a final declaration for each tax year.
The process will look like this:
- Quarterly Updates: Every three months, you will send a summary of your rental income and expenses to HMRC through your compatible software. This is not a full tax return and won’t require complex calculations.
- End of Period Statement (EOPS): At the end of the tax year, you will finalise your business income by making accounting adjustments and claiming any reliefs.
- Final Declaration: This is where you will declare any other income (such as employment or savings interest) and finalise your overall tax liability for the year.
This new rhythm requires a more disciplined approach to bookkeeping throughout the year, rather than a last-minute scramble in January.
3. Digital Records and Compatible Software are Mandatory
Under MTD, you can no longer keep your records solely on paper or in a simple spreadsheet. You are required to use “functional compatible software” that can connect directly to HMRC’s systems to submit your updates.
This means you will need to choose a software solution that is recognised by HMRC. These platforms are designed to make MTD simpler by:
- Recording income and expenses in real-time.
- Categorising transactions correctly.
- Keeping a running estimate of your tax bill.
- Submitting your quarterly updates directly to HMRC with just a few clicks.
You should start researching MTD-compatible software from the list on HMRC’s website now to find one that suits your needs and budget.
4. You Must Know the New Deadlines
The MTD system operates on a new set of deadlines that every landlord must learn. For a standard tax year running from April 6th to April 5th, the quarterly submission deadlines are as follows:
- Quarter 1 (6 April – 5 July): Submission due by 5 August
- Quarter 2 (6 July – 5 October): Submission due by 5 November
- Quarter 3 (6 October – 5 January): Submission due by 5 February
- Quarter 4 (6 January – 5 April): Submission due by 5 May
Your End of Period Statement and Final Declaration will still be due by 31 January of the following year. It is crucial to get these new dates into your calendar to avoid automatic penalties for late submissions.
5. Early Preparation is Key (and It Has Benefits)
While MTD introduces new obligations, it also offers tangible benefits for landlords. Keeping up-to-date digital records gives you a much clearer, real-time view of your portfolio’s financial performance. The running tax calculation provided by most software also means no more surprises when the bill is due, allowing for better financial planning and cash flow management.
To prepare, you should take these simple steps now:
- Confirm Your Start Date: Calculate your total gross income from property and self-employment to determine if you fall into the 2026 or 2027 start date.
- Go Digital Now: Don’t wait for the deadline. Start using software to track your income and expenses immediately to get comfortable with the process.
- Choose Your Software: Research and select an HMRC-approved accounting software package that works for you.
- Talk to Your Accountant: If you use an accountant, discuss how they will manage your MTD submissions and what information they will need from you on a quarterly basis.
By taking these steps today, you can turn a regulatory requirement into a strategic advantage for managing your property business more effectively.
MTD for Landlords: Frequently Asked Questions (FAQs)
Is the MTD income threshold based on my profit or my total rental income?
The threshold is based on your total gross income (also called turnover), not your final profit after expenses. You must add together all your rental income plus any income from self-employment to see if you exceed the £50,000 threshold for the April 2026 start date, or the £30,000 threshold for the April 2027 start date.
I own a property jointly with my spouse. How does the threshold apply to us?
For jointly owned properties, you must look at your individual share of the rental income. For example, if a property you own 50/50 generates £60,000 in rent per year, your personal qualifying income from that property is £30,000. You would then add this to any other personal income from self-employment to see if you, as an individual, need to register for MTD.
Does MTD mean I have to pay my tax quarterly?
No. This is a common misconception. MTD changes the way you report your income to HMRC, requiring quarterly updates. However, the deadlines for paying your income tax currently remain the same (31st January and 31st July). Your MTD software will provide a running estimate of your tax bill, but the actual payment schedule has not yet changed.
Can I claim the cost of MTD software as a business expense?
Yes, absolutely. The subscription costs for HMRC-approved MTD software are a fully allowable business expense. You can deduct this cost from your rental income, which will help reduce your overall taxable profit.
My accountant handles my tax return. Do I still need to do anything for MTD?
Yes. Even if you use an accountant, you are still legally responsible for keeping accurate digital records of your income and expenses. You will need to use MTD-compatible software to log your transactions. Your accountant can then access this digital information to prepare and file the necessary quarterly and final declarations on your behalf. It’s crucial to speak with them about how you will work together under the new system.
Are there any exemptions from Making Tax Digital?
HMRC has a very small exemption category for those who are “digitally excluded.” This may apply if you cannot use digital tools due to age, disability, remoteness of location (e.g., no internet access), or other specific reasons. This is not an automatic exemption; you must apply to HMRC and get their official approval to continue filing paper tax returns.
