MTD Software for Landlords 2026: Requirements & How to Choose

Do landlords actually need MTD software?

Yes — if you fall within Making Tax Digital for Income Tax, software is not optional. MTD for Income Tax replaces the annual Self Assessment process with quarterly digital reporting, and the only way to send those quarterly updates is through software that connects to HMRC's MTD API. There is no manual web form for quarterly updates.

Three obligations sit at the heart of MTD, and each one requires compatible software:

• Digital record keeping. Every item of property income and allowable expense must be recorded digitally, close to the time of the transaction.
• Quarterly updates. You send a cumulative summary of income and expenses to HMRC four times a year.
• Final declaration. After the tax year ends, you finalise your figures, add any other income, and confirm your tax position — all through software.

Paper ledgers and standalone spreadsheets no longer meet the requirement on their own. A spreadsheet can still be used, but only if it is joined to HMRC by bridging software with an unbroken digital link — meaning you must never manually retype figures from one place to another. For most landlords, a purpose-built tool is simpler and less error-prone than a compliant spreadsheet plus bridging setup.

Who has to comply, and from when?

MTD for Income Tax is being introduced in phases based on your qualifying income — your gross property rents and any self-employment turnover, before deducting expenses, taken from your latest finalised Self Assessment return.

Because the threshold counts gross income across all your property and self-employment combined, many landlords who consider themselves “small” are caught earlier than they expect. A landlord with two buy-to-lets renting at £1,300 and £1,200 a month already has £30,000 of gross rents — enough to be inside the April 2027 phase, and a third property would push them into the first 2026 cohort. Use our MTD readiness checker to confirm which phase applies to you.

The quarterly deadlines your software must hit

Once you are in MTD, your software must submit four quarterly updates for each tax year. For the standard quarters, the deadlines are the same every year — always the seventh of the month after the quarter ends.

Quarterly updates are cumulative and do not trigger a tax payment — your tax is still due by 31 January, with payments on account where they apply. But missed quarterly updates attract points under HMRC's penalty regime, so software that reminds you and submits on time matters. For the exact dates and penalty rules, see our MTD quarterly deadlines 2026 guide.

What to look for in MTD software for landlords

Not every accounting package suits landlords. Generic bookkeeping tools are built for invoicing and VAT, not property income. Use this checklist to compare options against what landlords actually need.

1. It must be on HMRC's recognised list — non-negotiable

Only software that HMRC recognises for MTD for Income Tax can submit your updates. Before you pay for anything, confirm the product appears on the official list at gov.uk. A polished interface means nothing if the tool cannot file.

2. SA105 categorisation built for property

Your property income and expenses are reported under the SA105 categories — rents received, premiums, rent and rates, repairs and maintenance, finance costs, legal and professional fees, and so on. Good software maps each transaction to the correct category. The treatment of finance costs (mortgage interest) is especially important: under Section 24, mortgage interest is not a simple deduction but a 20% basic-rate tax credit, and software should handle that distinction correctly. See our Section 24 mortgage interest guide for the detail.

3. Bank-statement import, not manual typing

The single biggest time saving comes from importing transactions directly from your bank statements or a CSV, rather than typing each line. Software that reads your statements and proposes a category for every transaction turns hours of quarterly admin into minutes of review.

4. AI categorisation with a confidence score

AI categorisation is only trustworthy when it tells you how sure it is. LandlordTaxAi scores every categorisation from 0 to 100 and flags anything below 90 for human review, defaulting to the conservative (non-deductible) treatment when uncertain. That keeps you safe from over-claiming, which is exactly what HMRC scrutinises.

5. All four updates plus the final declaration

Some cheap tools only submit a single quarterly update and leave you to handle the year-end yourself. Confirm the price covers all four quarterly updates and the final declaration that replaces your old Self Assessment return.

6. Multi-property and joint-ownership support

If you own more than one property — or own jointly with a spouse — your software should track each property separately and split joint income correctly, because joint owners each report their share.

7. A clear audit trail and export

You should be able to export a clean record of what was submitted and when. LandlordTaxAi produces downloadable PDF summaries for every quarter and the year, so you and your accountant always have a paper trail.

How much does MTD software for landlords cost?

In 2026, HMRC-recognised MTD software for landlords generally costs between around £10 and £40 per month, depending on the number of properties and the level of automation. HMRC also lists some free and low-cost bridging options, though these are usually bare-bones and assume you already keep compliant digital records elsewhere.

When you compare prices, check three things: whether the figure is billed monthly or annually, whether it covers all four quarterly updates and the final declaration, and whether bank-statement import is included or charged as an add-on. LandlordTaxAi pricing is transparent and starts at £19/month for one to two properties, £39/month for three to ten, and £69/month for eleven or more — with no lock-in. See full pricing here.

How to choose and switch before the deadline

Leaving software until March 2026 is the most common mistake. Switching is far easier if you start a quarter or two early so the first real submission is not also your first time using the tool. A sensible path:

1. Confirm your qualifying income and which MTD phase applies to you.
2. Shortlist two or three tools that appear on HMRC's recognised-software list and support property income — our ranked comparison of MTD software for landlords is a good starting point.
3. Trial the categorisation on your real bank statements — accuracy on your own data is the truest test.
4. Check the price covers all four quarterly updates and the final declaration.
5. Connect the software to HMRC and run a practice quarter before 6 April 2026.
