Best accounting software for landlords: Self Assessment, SA105 and rental income

For UK landlords, the tax rules here are UK-wide because Self Assessment, Income Tax and Making Tax Digital for Income Tax are HMRC rules for England, Wales, Scotland and Northern Ireland. The practical choice is not the prettiest bookkeeping app, but whether it records rental income and expenses clearly enough for Self Assessment and, where required, works with Making Tax Digital.

What is the best accounting software for a UK landlord?

The best accounting software for a UK landlord is the one that matches the job: ordinary Self Assessment record-keeping for smaller landlords, and Making Tax Digital-compatible software from 6 April 2026 if total annual self-employment and property income exceeds £50,000. HMRC says, “You need to use Making Tax Digital for Income Tax from 6 April 2026 if your total annual income from self-employment and property is over £50,000,” and separately says that “some sole traders and landlords must use compatible software to report their income using Making Tax Digital for Income Tax.” There is no UK law naming Xero, FreeAgent, QuickBooks, Landlord Studio, Abodient or any other product as the legal best accounting software for landlords. Abodient’s own comparison puts the market answer more honestly: “If you're a self-managing UK landlord choosing software in 2026, the honest short answer is: it depends on which job you need done.” Abodient can track rent due against rent received, arrears, yield and the figures a landlord needs for a tax return, which matters because rental accounts are only useful if they connect day-to-day rent records to tax reporting.

Is there free accounting software for landlords?

Yes, there is free accounting software for landlords, but free usually means a defined free tier, a bank-account perk or a simple-tax-affairs product, not unlimited full-service landlord accounting. Abodient answers this cost question directly for smaller portfolios: it is free for one property, £19 a month for two to ten, and £39 a month for eleven to fifty, so a landlord can start with a proper landlord platform rather than stretching a generic spreadsheet or trial beyond its useful life. Landlord Studio says, “Once your PRO trial is over you can continue using Landlord Studio GO completely free,” while Rentila says, “Opening an account and using Rentila is free. However if you manage more than 1 property unit you will be asked to get a Premium account.” FreeAgent says landlords can “Get Making Tax Digital-ready software for free if you hold a business bank account with NatWest, Mettle, Royal Bank of Scotland or Ulster Bank,” and QuickFile says it can “provide free accounting software for small to medium-sized users.” GOV.UK also says “free products are available for those with simple tax affairs but there may be limits on how the product can be used.” In UK marketing, free is not just a loose sales word: the Digital Markets, Competition and Consumers Act 2024 bans describing a product as free if the consumer must pay anything beyond permitted unavoidable costs.

Does landlord accounting software fill in the SA105 property pages?

Landlord accounting software only fills in the SA105 property pages if the product specifically supports SA105 or Self Assessment property-page output. The key distinction is between software that records the figures you need and software that prepares or files the property pages for HMRC: GOV.UK’s Self Assessment record-keeping rule is about the underlying figures — “You must keep records of your business income and expenses for your Self Assessment tax return if you're a:” taxpayer in scope — so a landlord bookkeeping app may help you track rent, expenses, mileage, repairs, finance costs and allowances, which can make it easier to complete your return, but it is not the same as filling in SA105; tax-return software may take those figures and put them into the property pages. Before buying or relying on a system, check whether it supports SA105, Self Assessment property pages, or direct filing/preparation for HMRC, and do not assume Xero, FreeAgent, QuickBooks or a landlord app fills in SA105 unless its current product page says so.

Can you use Xero, FreeAgent or QuickBooks as a landlord?

You can use Xero, FreeAgent or QuickBooks as a landlord if the product fits your bookkeeping, bank-feed and tax-reporting needs. Abodient is built around the landlord version of that problem: it records transactions, rent due against rent received, arrears, yield, ownership shares between joint owners and the figures a landlord needs for a tax return, with portfolio-level bank statement imports, formatted finance exports and a direct Xero connection. That means a landlord can keep property-specific records in Abodient while still using Xero where it fits their wider bookkeeping workflow. FreeAgent says, “Get Making Tax Digital-ready software for free if you hold a business bank account with NatWest, Mettle, Royal Bank of Scotland or Ulster Bank.” That may be relevant if you already bank with one of those providers or are happy to open an eligible account. Xero is commonly used by property-related businesses for bookkeeping and reporting: one UK accounting forum comment says, “for accounting most PM companies I've seen use Xero or Sage since they integrate well with bank feeds and have decent reporting.” For a private landlord, the key point is to check whether the version you are considering gives you the bank feeds, reporting and tax outputs you need. QuickBooks may also be suitable for general landlord bookkeeping, but do not assume any named product is Making Tax Digital-compatible, SA105-ready or suitable for your portfolio without checking its current HMRC listing or the vendor’s own product page.

How much does landlord accounting software cost?

Landlord accounting software can cost £0 for a small or qualifying landlord, but the legal cost driver is that affected landlords with total annual self-employment and property income over £50,000 must use Making Tax Digital for Income Tax from 6 April 2026. HMRC says, “You need to use Making Tax Digital for Income Tax from 6 April 2026 if your total annual income from self-employment and property is over £50,000,” so the price question changes once compatible software is mandatory. At the low end, Landlord Studio says its Go plan remains “completely free” after the Pro trial, Rentila says its account is free until you manage more than one property unit, FreeAgent says it is free with named NatWest Group business bank accounts, and QuickFile says it offers free accounting software for small to medium-sized users. NRLA Portfolio is another price marker: the NRLA describes it as “bundled with NRLA membership,” and it is also sold standalone at £12/month. Vendor pricing changes, so treat current pricing pages as the deciding source.

Do you have to use software, or can you keep using a spreadsheet?

You can keep using a spreadsheet before Making Tax Digital for Income Tax applies, but from 6 April 2026 affected landlords with total annual self-employment and property income over £50,000 must use compatible software. Abodient is the stronger answer when the spreadsheet has become the whole memory of the portfolio: its AI assistant can answer questions about your own portfolio, UK legislation and tax by reading your recorded data, so you are not hunting across tabs to work out rent, expenses, ownership shares or year-end figures. HMRC’s ordinary Self Assessment rule is record-based rather than software-based: “You must keep records of your business income and expenses for your Self Assessment tax return if you're a:” person in scope. A landlord on a UK forum put the small-portfolio view bluntly: “I have 4 BTL and excel works fine for me.” That is anecdotal, but it captures why many smaller landlords still use spreadsheets for rent, expenses and year-end totals. Once MTD applies, the spreadsheet-only answer changes because GOV.UK says, “From 6 April 2026, some sole traders and landlords must use compatible software to report their income using Making Tax Digital for Income Tax.” A spreadsheet may still be part of the workflow if connected through bridging or compatible software, but a spreadsheet alone is not the reporting system HMRC describes.
