Low Cost MTD Software UK 2026: 10 Affordable Options Ranked

Making Tax Digital for Income Tax Self Assessment becomes mandatory in April 2026 for landlords earning over £50,000 gross — and finding affordable, reliable software to comply has become the top priority for nearly three million UK landlords. The problem is not a lack of options. It is that the sheer volume of MTD-compatible platforms makes it nearly impossible to tell which ones deliver genuine value and which ones simply tick the HMRC recognition box while leaving landlords to fend for themselves.

We tested 10 MTD-compatible platforms head-to-head over a six-week evaluation period, scoring each on MTD compliance quality, annual cost, landlord-specific features, ease of use, and overall value for money. Every platform was assessed at four portfolio sizes — 1, 5, 10, and 20 properties — because software that seems cheap for a single property can become expensive as your portfolio grows, and vice versa.

This is the definitive ranking of low-cost MTD software for UK landlords in 2026. Whether you own one buy-to-let or manage a growing portfolio, this guide will help you find the right balance of compliance, capability, and cost.

What Makes MTD Software "Low Cost"?

Before ranking anything, we need to define what "low cost" actually means in the context of MTD software for UK landlords. It is not simply the cheapest sticker price. A platform that charges nothing but forces you to spend five hours manually categorising expenses every quarter is not truly low cost — it is transferring the cost from your bank account to your time.

We set four criteria that every platform had to meet to qualify as genuinely low cost for this ranking. These criteria separate the platforms that deliver affordable compliance from those that merely appear cheap on paper.

How We Ranked These 10 Platforms

Each platform was scored across five weighted criteria designed to reflect what actually matters to UK landlords choosing affordable MTD software. The weighting system prioritises value and compliance over raw feature count — because a platform that costs nothing and submits correctly to HMRC is more useful to most landlords than an expensive tool with dozens of features they will never use.

The Value Score is a composite metric that weighs what you get against what you pay. A free platform with limited features can score higher than an expensive platform with extensive features if the free platform covers the essentials well. Conversely, a modestly priced platform that saves significant time through automation scores higher than a free tool that creates manual work.

All testing was conducted between January and March 2026 using real property data across multiple portfolios. Pricing was verified directly from each platform's website as of March 2026. For a detailed cost breakdown at every portfolio size, see our cheapest MTD software comparison.

The Complete Ranking

Here are all 10 low-cost MTD platforms ranked by our composite Value Score, which combines compliance quality, annual cost, landlord features, and ease of use into a single comparable metric. Detailed individual reviews follow the table.

Individual Reviews

1. Latch Free — Best Overall Value

Latch Free takes the top spot because it is the only platform that combines full MTD compliance, genuine property management features, and a £0 price tag. Most free MTD tools give you a submission mechanism and little else. Latch gives you compliance tracking, tenant management, expense recording, bank feeds, and AI-powered categorisation — all within the free tier for up to 3 properties.

The platform was purpose-built for UK landlords, which means every feature maps directly to the realities of managing rental property in England, Scotland, Wales, or Northern Ireland. Expense categories align with HMRC's SA105 form, compliance certificates are tracked against statutory deadlines, and quarterly MTD submissions are generated from your existing records with minimal manual intervention. For landlords with 1 to 3 properties who want comprehensive software without paying a penny, there is nothing else on the market that matches it. For more detail on how Latch compares in the budget category, see our four-way comparison guide.

2. Hammock — Best Flat-Rate for Landlord Tax

Hammock earns second place by doing one thing extremely well: landlord tax management at a fair, predictable price. At £8 per month (£96 per year), it is the most affordable paid platform on this list, and its flat-rate pricing means costs stay the same whether you have 1 property or 50. For landlords who want a step up from free tools but do not need full property management, Hammock hits a sweet spot.

Where Hammock falls short is in breadth. It is a financial and tax tool, not a property management platform. You will not find tenant communication, maintenance tracking, compliance certificate management, or AI-powered automation. If your primary need is MTD compliance with solid income and expense tracking, Hammock delivers. If you need a broader operational platform, you will need to supplement it with other tools — or choose a more comprehensive option like Latch.

3. GoSimpleTax — Best for Self Assessment Focus

GoSimpleTax is the strongest option for landlords who already manage their properties effectively using other tools (or manually) and simply need an affordable way to file their Self Assessment with MTD compliance. At £40-60 per year, it is one of the cheapest paid options available, and its step-by-step approach to completing the SA105 property income pages makes it accessible even for landlords who have never filed digitally before.

The trade-off is clear: GoSimpleTax does tax, and only tax. There is no property management, no tenant database, no compliance tracking, no bank feeds, and no automation. You bring your figures, GoSimpleTax helps you file them correctly. For landlords who are comfortable with that division of labour, it represents excellent value. For those who want a single platform to handle both management and tax, it will leave significant gaps.

4. Latch Pro — Best Full Property Management

Latch Pro ranks fourth on value rather than capability. It scored the highest MTD Compliance and Landlord Features ratings of any platform tested — a perfect 5.0 in both categories. What brings its Value Score down is simply its price: at £20 per month, it costs more than tax-only tools like GoSimpleTax or flat-rate options like Hammock. But that comparison misses the point. Latch Pro is not a tax tool; it is a complete property management platform that happens to include the best MTD compliance on the market.

For landlords with 4 or more properties, Latch Pro often delivers better overall value than combining a free MTD tool with separate property management. The AI agent alone — which can autonomously chase rent, draft tenant communications, and analyse documents — saves hours each month. Add Open Banking, compliance tracking, e-signatures, and SA105-ready reporting, and the £20/month price becomes easy to justify.

5. QuickFile — Best Free General Accounting

QuickFile is the most feature-rich free accounting platform available to UK landlords. It handles MTD submissions, offers bank feeds, includes invoicing, and costs nothing if your turnover stays below £45,000. For landlords comfortable with accounting software, it provides a solid foundation for MTD compliance without any subscription cost.

The catch is that QuickFile was built for general small businesses, not landlords. You will need to create your own property income categories, manually map expenses to SA105 deduction types, and build your own reporting to extract the figures you need for Self Assessment. It works, but it requires more setup and ongoing manual effort than purpose-built landlord platforms. The ad-supported interface is also a consideration — banner advertisements appear throughout the platform on the free tier.

6. ANNA Money — Business Banking with MTD

ANNA Money combines a business bank account with built-in MTD compliance, which makes it appealing for landlords who want to consolidate banking and tax filing into a single platform. The free tier includes a business current account and basic MTD submissions. The paid tier (£11/month) adds invoicing, receipt scanning, and automated expense categorisation.

The limitation is that ANNA Money is a banking product first and an MTD tool second. Property-specific features are minimal, and landlords with multiple properties may find the reporting too basic for effective portfolio management. It works best for landlords with 1-2 properties who want their business banking and MTD compliance in one place.

7. Taxd — AI-Assisted Tax Filing

Taxd uses AI to simplify Self Assessment, automatically reviewing your tax return for errors and suggesting deductions you may have missed. At £50-80 per year, it sits in the same price bracket as GoSimpleTax but differentiates itself with its AI review functionality. The platform walks you through each section of your return with plain-English explanations.

For landlords, Taxd's AI review can catch commonly missed property deductions — mortgage interest relief calculations, wear and tear allowances, and travel expense eligibility. However, like GoSimpleTax, it is a tax-only tool with no property management capabilities. The AI features are helpful but do not extend to day-to-day property operations.

8. FreeAgent (via NatWest) — Free for NatWest Customers

FreeAgent is a well-established accounting platform that NatWest offers free to its business banking customers. Without the NatWest tie-in, it costs £14/month (£168/year), which places it at the upper end of our low-cost range. FreeAgent handles MTD compliance competently, offers solid bank feeds, and provides a polished interface — but it is designed for freelancers and small businesses rather than landlords.

If you already bank with NatWest and qualify for the free subscription, FreeAgent is a strong MTD option at zero additional cost. If you would need to pay the full £168/year, other platforms on this list offer better value for landlord-specific needs. The property income setup requires manual configuration, and there are no compliance tracking or tenant management features.

9. Clear Books — Small Business Accounting

Clear Books is a straightforward cloud accounting platform at £12/month (£144/year) with MTD compliance included. It handles the fundamentals — invoicing, expense tracking, bank reconciliation, and VAT/MTD submissions — in a clean interface. However, it offers nothing specific to landlords and sits in a crowded mid-price range where more capable alternatives exist.

At £144/year, Clear Books costs more than Hammock (£96/year) while offering fewer landlord features, and costs less than Latch Pro (£240/year) while offering significantly less capability. It is a competent general accounting tool but struggles to justify its position when landlord-specific platforms exist at both lower and similar price points.

10. RentalBux — Absolute Basics Only

RentalBux rounds out the list with a free platform that covers the bare minimum for MTD compliance. It handles basic rent and expense tracking with MTD-compatible submissions to HMRC. The interface is simple, the feature set is limited, and the user base is small. There are no bank feeds, no compliance tracking, no AI features, and minimal reporting.

RentalBux is best suited for landlords with a single property who want the absolute simplest route to MTD compliance and are comfortable handling everything else manually. For any portfolio beyond one property, the lack of automation and features will create more work than it saves. Consider Latch Free instead, which offers the same £0 price point with substantially more capability.

Price Comparison by Portfolio Size

The annual cost of MTD software changes significantly depending on how many properties you manage. Some platforms charge a flat rate regardless of portfolio size, while others scale per property or by tier. The table below shows the real annual cost for each platform at four portfolio sizes, helping you identify which option is most cost-effective for your specific situation.

Several patterns stand out. Free platforms (Latch Free, QuickFile, RentalBux) maintain zero cost but impose feature limitations that become more painful as portfolios grow. Tax-only tools (GoSimpleTax, Taxd) charge the same flat annual fee regardless of portfolio size, making them increasingly cost-effective per property at scale — but they offer no management features. Latch Pro is the only platform where the cost increases with portfolio size (beyond 8 included properties), but the per-property increment of £1/month is modest.

Which Is Right for You?

The right MTD software depends on three factors: how many properties you manage, how much time you want to spend on administration, and whether you need property management features alongside tax compliance. Here is a quick decision guide based on the four most common landlord scenarios.

If you are still unsure, consider this: the cost of a missed deduction or a late compliance certificate far exceeds the annual subscription of any platform on this list. A single missed Gas Safety inspection can result in a £6,000 fine. A poorly categorised expense that triggers an HMRC enquiry can cost thousands in accountancy fees to resolve. The right software is an investment in risk management, not just a tax filing tool.
