Landlord accounting software: UK options compared

Landlord accounting software records your rental income and expenses, reconciles rent against your bank account, and produces the figures you need for Self Assessment and Making Tax Digital. For a UK landlord it does the job a shoebox of receipts and a year-end spreadsheet used to do, but continuously, and in a format HMRC now expects. This guide explains what the software does, the features that matter, how to check a platform handles property tax correctly before you commit, and how the main options compare, from purpose-built landlord tools to all-in-one property platforms and general accountancy packages. It is written for self-managing landlords deciding how to keep their books in 2026.

What landlord accounting software actually does

Landlord accounting software is a tool for keeping the financial records of a rental business: the income, the expenses, and the documents that support them. At its core it does four things. It captures rental income and matches each payment to the right tenancy, it records and categorises expenses against HMRC's property income categories, it reconciles those transactions against your bank account, and it produces reports such as a profit and loss statement that you or your accountant can use at year end. The formal category definition sits in our dictionary entry on property management accounting software; this guide is about choosing between the products.

It helps to draw one boundary early. Accounting software keeps the books. Tax software prepares and files the return, applying allowances and reliefs. Making Tax Digital software handles the quarterly submission to HMRC. In practice the better tools blur all three, because clean accounting records are what let the return and the quarterly update fall out of the same data, but the labels describe different jobs and buying the wrong one is a common and expensive mistake.

Do you need dedicated software, or will a spreadsheet do?

A spreadsheet can record rental income and expenses accurately, but on its own it no longer satisfies a landlord's tax obligations once Making Tax Digital applies. The rules require an unbroken digital link from your bank transactions through to the quarterly submission, and re-typing figures from a spreadsheet into a filing tool breaks that link. A spreadsheet remains workable only where it connects to HMRC through bridging software that preserves the link, which suits some landlords with one or two properties below the threshold but adds a moving part rather than removing one.

Landlords who move to August from spreadsheets describe the same pattern. The spreadsheet held up for the first year, then drifted as tenancies changed and receipts went missing, and the switch usually came after one painful Self Assessment rather than before. If you are weighing the cost of software against the tax at stake, our rental income tax calculator gives you a quick estimate of the bill those records will feed.

What to look for in landlord accounting software

The features that separate good landlord accounting software from generic bookkeeping tools are built around how a rental business actually runs. Five matter most.

Automatic bank feeds and reconciliation. An Open Banking connection that pulls transactions in and matches incoming rent to the right tenancy removes the largest single piece of manual work, and flags late or partial payments as they happen.

Property-level tracking, not aggregate. Income, expenses and profit should be visible for each property separately. The common failure among landlords who track everything in one pot is a reconciliation headache at every deadline.

HMRC-aligned expense categories. Expenses should map to the SA105 property income categories as you record them, so the year-end return is a summary rather than a sorting exercise.

Profit and loss and accountant-ready exports. Clean statements you can hand over without reformatting save accountant time, which is billed by the hour.

MTD-ready records, and submission where you need it. The software must keep records to HMRC's digital standard, and either submit the quarterly updates itself or export cleanly to a tool that does.

August logs every expense in HMRC-aligned categories automatically and lets you attach a receipt photo to the transaction, which is the expense tracking groundwork the rest of your tax year depends on.

Two calculations to check before you commit

Feature lists are easy to compare. The two things that actually go wrong are harder to see from a pricing page, and both are calculations rather than features.

Mortgage interest. Since April 2020, an individual landlord cannot deduct mortgage interest from rental income before calculating profit. Interest is not deductible against rental profit; a 20% credit applies instead. Software that treats interest as an ordinary expense category will understate the liability, and for a higher-rate taxpayer paying £10,000 a year in interest the gap is £2,000 a year. Ask any provider directly whether the platform records mortgage interest separately and applies the credit at the calculation stage. If the answer describes interest as an expense category, the figures will be wrong.

In our experience supporting landlords through this, the error almost never originates in the software. It arrives with the landlord, carried over from a spreadsheet that deducted interest in full, and generic bookkeeping tools accept it without objection. In August, interest sits outside the deductible ledger and the credit is applied at calculation, so how August records mortgage interest does not depend on the landlord knowing to configure it.

Repairs against improvements. Repairs are allowable against rental profit. Improvements are capital and are not. Generic accounting software leaves the judgement entirely to you, which means the classification happens at year end, from memory, months after the invoice. The repairs and improvements line is where most landlords lose deductions. August separates day-to-day costs from capital expenditure at the point of entry rather than at year end.

The three types of accounting software for landlords

Landlord accounting software comes in three broad shapes, and the right one depends on whether you want a finance tool, a property tool, or both.

The purpose-built tools lead with the ledger and add property features around it. The generic packages are powerful and familiar to accountants, but they treat a rental like any other small business, so the property structure is something you build yourself. The all-in-one platforms come at it from the other direction, putting the tenancy at the centre and keeping the financial record alongside the rent, compliance and documents.

Across the portfolios managed on August, the landlords who settle fastest are the ones who stopped running a separate accounting app next to their property admin. Keeping the rent record and the expense record in the same place as the tenancy removes the reconciliation step rather than automating it. If you want to compare platforms on more than their accounts, our guide to the best property management software for UK landlords weighs them on rent tracking, compliance and maintenance too, and our head-to-head with Hammock covers the accounting-led comparison in detail. If you are narrowing down on price, what the plans cost is set out in full.

Will my accountant be able to work with it?

Most landlords beyond a handful of properties work with an accountant, and most UK accountants work in Xero. A platform that forces the accountant into an unfamiliar landlord app creates friction that usually ends with the landlord exporting spreadsheets anyway, which defeats the point.

Software that connects to Xero lets the property records and the ledger stay in step without either side rekeying. August, Landlord Studio, Landlord Vision, Arthur and COHO all offer a Xero connection, so this is now a baseline to check rather than a way to choose between them. What still differs is what reaches Xero and in what shape, so ask what records sync and whether each property maps to a tracking category, since that is what makes property-level reporting possible on the accounting side.

This also settles a question that used to force a choice. A landlord whose accountant works in Xero no longer has to pick between the ledger their accountant knows and a platform built around tenancies. Running one in front of the other gives both.

Where accounting software meets Making Tax Digital

Making Tax Digital for Income Tax changes what your accounting records have to do, not just how you file. As at August 2026, landlords with qualifying income above £50,000 must keep digital records and send HMRC quarterly updates using recognised software, with the threshold falling to £30,000 from April 2027 and £20,000 from April 2028, set out in HMRC's guidance on using Making Tax Digital for Income Tax. Qualifying income is combined gross income from property and self-employment before expenses, not property income alone, which catches landlords who assume a rent roll below £50,000 puts them outside the regime.

Your accounting software's job here is to keep the digital records and preserve the digital link from bank transaction to submission. Whether your software also makes the submission is a separate decision, and our Making Tax Digital hub sets out the mechanics and the deadlines. HMRC draws a line between software that is merely able to submit and software that maintains full digital links from source records through to filing, and the practical difference is whether your bank feed flows through untouched or you re-key figures along the way. For the submission decision specifically, our comparison of the best MTD software for landlords covers the recognised options.

Free landlord accounting software: where free runs out

Free landlord accounting software exists, but the free tiers stop short exactly where MTD compliance and multi-property tracking begin. A free plan typically covers one or two properties with basic income and expense logging, which is enough to test an interface and to keep simple records below the MTD threshold. The features that tend to sit behind a paid plan are the ones that save the most time: Open Banking bank feeds, quarterly MTD submission, compliance tracking and clean accountant exports. Our guide to free landlord software in the UK sets out what each free tier includes and the point at which free stops being enough.

How to choose

Choose landlord accounting software on four things: whether it reconciles rent automatically, whether it tracks each property separately, whether it applies the mortgage interest credit correctly, and whether it keeps MTD-ready records you can hand to an accountant without reformatting.

A landlord with one or two properties and simple needs can start on a free tier and upgrade when MTD applies. A landlord in the four-to-fifteen range, where multiple due dates and overlapping deadlines start to bite, gains most from automatic bank feeds and per-property records. Finance-led landlords with complex tax affairs may want the depth of a dedicated accounting tool, while landlords who would rather keep the books, the rent and the compliance in one place are better served by an all-in-one platform that feeds their accountant's ledger rather than replacing it.

August produces property-level profit and loss and accountant-ready exports as standard, so the year-end hand-off is a download rather than a rebuild. The financial reports are built for exactly that moment.

Frequently asked questions

Do I need accounting software for one rental property? Usually it is worth it. Even one buy-to-let has deductible expenses, an SA105 page at year end and, once your income crosses the threshold, a quarterly MTD obligation. A free tier is a sensible way to start with a single property, and a paid plan tends to justify itself from two or three. Our analysis of what landlord software saves in practice quantifies that across time, tax capture and penalty risk.

Can I use Xero or QuickBooks as a landlord? Yes, and many accountants prefer them, but they are general business tools rather than property tools. There is no tenancy tracking, no compliance reminders and no certificate storage, and both property-level reporting and the Section 24 treatment need manual setup. The better approach for most landlords is not to choose: keep the property records in a landlord platform and connect it to the ledger your accountant already uses.

How do I know if software handles Section 24 correctly? Ask the provider whether mortgage interest is recorded separately from allowable expenses and whether a 20% credit is applied at the calculation stage. If interest appears as an ordinary expense category, the platform will understate your liability. This is worth confirming in writing before you commit, whichever platform you choose.

Is there free accounting software for landlords? Several platforms offer free tiers covering basic rent and expense logging for one or two properties. They are a good way to test a tool, but most withhold bank feeds, MTD submission and compliance tracking until you pay, which is where the real time saving lives.

Does accounting software handle my MTD submission? Some products submit the quarterly updates for you and some only keep the records, leaving the submission to a separate tool. If MTD applies to you, check that the software appears on HMRC's list of recognised products before committing.

August's free plan covers up to two tenancies with rent tracking, expense logging and document storage, and paid plans from £8.99 a month add MTD reporting, Open Banking rent tracking and the Xero connection. You can start on the free plan and test it on your own portfolio.
