Making Tax Digital for Landlord Accounting: What’s Changed in 2026
With the announcement of Making Tax Digital, there have been a lot of changes, replacing the annual Self Assessment tax return with digital record-keeping and quarterly updates.
Who’s Affected Now?
MTD affects unincorporated landlords and employees who pay tax through Self Assessment. Whether you’re affected or not depends on whether or not you meet the phased thresholds based on your qualifying gross income. To find out more about the thresholds, take a look at our Making Tax Digital guide, where we get into more detail regarding the thresholds and what you can expect to pay.
Income Tax for Landlords: The Basics
While preparing for the changes caused by MTD, it’s important for landlords to understand the basics of income tax for landlords in the UK, with property and tax coming with their own complexities.
How Rental Income is Taxed
UK landlords pay income tax on their net rental profits, which are typically calculated by deducting allowable property expenses from total rental income. These profits are combined with other personal income, such as salaries, and reported yearly to HMRC via Self Assessment or under the MTD digital record-keeping requirements.
Why Landlord Accounting Includes Having to Use MTD
One of the main reasons HMRC is focusing on Landlords is to address the UK’s tax gap, as many landlords underpay what they owe. It is estimated that 60% of the total tax gap comes from Self Assessment business taxpayers, with landlords under scrutiny for not paying the correct amount.
Until recently, independent landlords have relied on manual logbooks, paper receipts and basic spreadsheets, leading to maths errors and misreported rental payments. Many landlords don’t even consult a property accountant, choosing to do it all in-house.
Landlords are not subject to strict corporate accounting standards, and MTD helps most private landlords move to a standardised, digital system.
Record Keeping Under MTD
Under MTD, landlords must ditch paper logs and keep live, digital records of all property and expenses using HMRC-recognised software. Using this software, landlord accounting means an expectation to submit quarterly updates and file an annual final declaration.
With the new regulations, you must keep accurate records of the date and amount for every rent receipt or property transaction, as discrepancies may have consequences.
Capital Gains Tax When You Sell
When you sell a rental property, Capital Gains Tax applies to the profit you’ve made since you bought it, not the total sale price. This is separate from MTD but ties into the same push for accuracy, since HMRC expects landlords to report gains promptly rather than waiting until the next tax return.
Since the reporting window tightened, landlords now have 60 days from completion to report the gain and pay any tax owed through the CGT on UK Property service. Missing this deadline can lead to penalties and interest, even if you eventually pay the tax correctly.
Working out the gain isn’t always straightforward. You can deduct costs like estate agent fees, legal fees, and certain capital improvements, but not general maintenance or mortgage interest. Landlords who’ve lived in the property at any point may also be able to claim Private Residence Relief for that portion of ownership, which reduces the taxable gain further.
Given the short reporting window and the number of allowable deductions landlords often miss, getting this calculation right usually means speaking to a property accountant before the sale completes, not after.
Common Landlord Accounting Mistakes to Avoid
You might think it’s a good idea to handle your own landlord accounting, but property and tax can be incredibly complicated, which is why we always recommend working with an accountant to avoid the following mistakes.
Mixing Personal and Rental Finance
A big mistake that we see, not just with landlords, but across business owners, is mixing personal and business finance. The money you make from your properties should not go into a personal account, as this can cause confusion and create tax, legal, and cash flow problems for landlords.
This can cause you to miss valid deductions or have difficulty proving expenses. It also makes it harder to track a property’s profitability and can create complications. If you currently use your personal account, we would strongly suggest opening a dedicated account for your rental properties.
Missing Quarterly MTD Deadlines
For anyone who is struggling to get used to MTD deadlines, you’re in luck for the 2026-2027 tax year, as there are currently no penalty points or fines due to HMRC treating this year as a ‘soft landing’ as businesses adjust to the new system.
However, you must still submit all past and missed updates before you can file your final year-end declaration.
From the next tax year, this all changes. Starting next year, each late quarterly submission will add one penalty point, and accumulating four penalty points will trigger a standard £200 fine, with an additional fine for every subsequent missed deadline.
To avoid penalties, file your reports on time, but we understand this can be difficult when you’re managing multiple properties. For this reason, we would recommend working with an accountant who can help you manage your tax responsibilities.
Under-Claiming or Over-Claiming Expenses
Getting expenses wrong can create substantial issues for landlords. Under-claiming leads to paying more tax than necessary because many landlords forget to include expenses such as letting agent fees, landlord insurance, ground rent, service charges, or the costs of replacing items like carpets and appliances. On the other hand, over-claiming can trigger an HMRC inquiry, which may require you to repay tax, plus interest and penalties.
A common source of confusion lies in distinguishing between repairs and improvements. Repairs, such as fixing a broken boiler or replacing a damaged fence, are generally allowable expenses. Whereas improvements, like adding an extension or upgrading a kitchen beyond its original standard, are classified as capital expenditures and are not deductible in the same way.
To make accurate, confident claims, keep clear records and receipts for every expense, and understand which category each cost falls into.
Not Planning for Tax Bills in Advance
One of the most stressful situations for a landlord is realising a tax bill is due and not having set aside enough to cover it. Rental income can feel like extra cash in the bank, but a portion of it will always need to go to HMRC, and treating it as spare income rather than income with a tax liability attached is a common mistake for landlord accounting. This is especially true around the July payment on account deadline, which catches a lot of landlords out.
A simple way to avoid this is to set aside a percentage of your rental income each month into a separate savings account as soon as it comes in, rather than waiting until your tax return is due to work out what you owe. This is especially important if you’re a higher-rate taxpayer or have several income-generating properties, as your tax bill can be larger than expected once everything is added together.
Working with an accountant throughout the year, rather than just at tax return time, can also help you estimate your liability in advance and avoid any last-minute surprises.
