Best accounting software for UK landlords: MTD IT 2026 guide

This guide covers what MTD IT means for landlords, the software options available, and how to choose the right approach for your property business.
Understanding MTD IT for rental property income
Making Tax Digital for Income Tax changes how landlords report rental income to HMRC. Rather than submitting one annual Self Assessment return, you'll maintain digital records throughout the year and send quarterly updates using HMRC-recognised software.
The system requires you to:
- Record your rental income and expenses digitally
- Submit four quarterly updates showing year-to-date totals
- Complete a final annual declaration by 31 January
Whether MTD IT applies to you depends on your qualifying income. This is the total gross income from any self-employment and property before expenses are deducted. HMRC determines who needs to join based on the 2024/25 Self Assessment return submitted by 31 January 2026, and has been writing to people affected.
HMRC is phasing in when people are required to join MTD IT and the date depends on your gross income:
April 2026: For those with gross annual income over £50,000
April 2027: For those with gross annual income over £30,000
April 2028: For those with gross annual income over £20,000
What landlords need from MTD IT accounting software
For MTD IT compliance, your accounting software must:
- Track rental income from all your properties
- Record allowable expenses (repairs, maintenance, insurance, mortgage interest, agent fees, professional costs)
- Appear on HMRC's list of recognised software products that integrate with their platform
- Connect directly to HMRC's systems for quarterly submissions
HMRC doesn't provide free software for MTD IT, so landlords need to select from available commercial options. HMRC has removed the gateway option for submitting your tax return for those mandated to use MTD IT.
Software approaches for property accounting
Landlords typically choose from three main approaches when managing their property accounts.
Specialist property management platforms
These combine tenant management, rent collection, and accounting features in one system. They suit landlords who want integrated operational and financial management.
General accounting software
Platforms such as QuickBooks or Xero can handle property accounting, particularly when used alongside other business activities. Many offer MTD IT compatibility with broader bookkeeping capabilities.

Quarterly reporting: what it involves
Quarterly updates under MTD IT show your cumulative position for the tax year to date. You'll report:
- Total rental income received
- Total allowable expenses incurred across all properties - either consolidated or categorised
These updates don't require detailed transaction-by-transaction reporting to HMRC. Instead, you just need to provide summary totals of your year-to-date figures, which keep your tax position current throughout the year. You'll still need to maintain detailed records for individual transactions, possibly in a spreadsheet or in TaxNav.
Even in quarters where you have minimal activity, an update is still required. Good digital record-keeping makes this routine rather than burdensome.
The importance of your final annual declaration
Your final annual declaration confirms your complete tax position for the year. This must be submitted by 31 January following the end of the tax year.
Important: You cannot file your annual declaration unless all four quarterly updates have been completed first.
Understanding penalties in your first year
In this first year of MTD IT, you won't be penalised for late or incorrect quarterly updates, but you must still submit all four using HMRC-recognised software. The year-end return is still fully subject to HMRC penalties if it's late, and you can’t file that until all four of your quarterly updates have been submitted.
To avoid a concentrated workload in January 2028, use the whole of the 2026/27 year to build your MTD IT familiarity and compliance.
If you work with an accountant:
They'll need appropriate digital authorisation to submit updates on your behalf. Have those conversations as soon as possible to ensure everything is in place.

How to get MTD-IT ready
If you haven't started yet, don't panic. Focus on these basics as, once those are in place, everything else follows naturally.
- Confirm if your gross income will trigger the MTD IT rules with HMRC's page
- Register with HMRC for MTD IT before you begin.
- Select your software - TaxNav offers a 30-day free trial
- Start keeping and recording your digital records - for example, directly into our software or in a spreadsheet using our bridging software. Until your final return, this does not need to be 100% accurate.
- Diarise when you need to submit your quarterly updates, TaxNav will remind you.
- Diarise your final (annual) declaration deadline.
People with income over £30,000 from self-employment and/or property will need to join MTD IT from April 2027. You can, however, volunteer to join early and get familiar with it before your HMRC deadline.
With TaxNav you automatically get a 30-day free trial and we offer low-cost subscriptions to keep things affordable. An annual subscription is £60+VAT or pay as you go for £6+VAT per month.
