Best MTD Compatible Software 2026 — Comparison

GoSimpleTax is purpose-built for UK tax returns and has added full MTD for Income Tax support. It guides you through the process step by step, which makes it particularly well-suited if you are new to digital record keeping or have straightforward self-employment income. The annual pricing model is attractive compared to monthly subscription tools if you only need tax filing rather than full accounting.

The platform calculates your tax liability in real time as you enter income and expenses, so there are no surprises at year end. MTD quarterly submissions are handled within the same interface, meaning you do not need separate tools for record keeping and HMRC submission.

The main limitation is that GoSimpleTax is focused on tax compliance rather than day-to-day accounting. If you need invoicing, bank feeds, or project tracking, you will need to look at a more comprehensive tool like FreeAgent or Xero.

FreeAgent is one of the most popular accounting platforms among UK freelancers and sole traders, and for good reason. It offers full double-entry accounting with an interface designed for non-accountants. Bank feed integration means transactions are pulled in automatically and can be categorised with a few clicks, which makes quarterly MTD submissions straightforward.

The platform includes invoicing, expense tracking, time tracking, and even basic project management. If you are a freelancer who needs to send invoices and track expenses alongside your MTD obligations, FreeAgent handles all of this in one place. It is also free for NatWest, Royal Bank of Scotland, and Ulster Bank business account holders.

The monthly cost can add up over a year compared to annual-payment tools like GoSimpleTax or TaxCalc. If you only need MTD compliance and do not require invoicing or bank feeds, FreeAgent may be more than you need.

Xero is a cloud accounting heavyweight with a massive app marketplace (over 1,000 integrations) and strong multi-currency support. If you have a growing business, multiple income streams, or work with an accountant who uses Xero, it is an excellent choice for MTD compliance.

The MTD for Income Tax features are built into Xero's existing accounting workflow, so quarterly submissions happen naturally as part of your bookkeeping. Bank rules and automatic categorisation reduce manual data entry significantly. The accountant access feature also makes it easy to collaborate with your tax adviser.

Xero's lower-tier plans have limitations (e.g., the Starter plan limits you to 20 invoices per month), so check you are on the right plan for your needs. The learning curve is also slightly steeper than FreeAgent or GoSimpleTax, though Xero's help resources are comprehensive.

QuickBooks is a strong all-round option, particularly for contractors and limited company directors. The mobile app is one of the best in the category, with receipt scanning and mileage tracking that make on-the-go expense recording genuinely easy. CIS (Construction Industry Scheme) support is also built in, which is a must-have for construction industry contractors.

For MTD, QuickBooks handles quarterly submissions and maintains your digital records in the format HMRC requires. The Self-Employed plan starts at £12/month, making it one of the more affordable monthly options. Bank feed integration and automatic categorisation are included on all plans.

QuickBooks has historically been stronger in the US market, and some users find that the UK-specific features (like VAT and MTD) feel bolted on rather than native. That said, Intuit has invested heavily in the UK product in recent years, and the MTD integration is now reliable.

TaxCalc is a professional-grade tax software that has been used by accountants and tax advisers for years. It handles complex tax situations — capital gains, foreign income, multiple property portfolios — with a level of detail that consumer-focused tools often lack. If your tax affairs are complicated, TaxCalc is worth serious consideration.

The MTD for Income Tax module integrates with TaxCalc's existing tax return workflow, so you can manage quarterly submissions and your final declaration from one platform. Both desktop and cloud versions are available, which gives flexibility in how you work. The annual pricing is competitive, especially if you value the depth of tax computation features.

The main downsides are the lack of a free trial and a more traditional interface that is less polished than newer cloud-first tools. TaxCalc also does not include invoicing or day-to-day bookkeeping features — it is focused squarely on tax compliance and computation.

Sage is one of the longest-established names in UK accounting software. If you are already using Sage for your business accounts, adding MTD for Income Tax is a natural extension. Sage Accounting (formerly Sage Business Cloud) includes inventory management, project tracking, and cashflow forecasting alongside the core accounting features.

For MTD compliance, Sage handles digital record keeping and quarterly submissions. The platform is well-suited to established businesses that need more than just tax filing — stock management, purchase orders, and multi-user access are all available. The 30-day free trial lets you evaluate whether it fits your workflow.

Sage can feel over-engineered for sole traders or freelancers with simple affairs. The interface is functional but not as intuitive as FreeAgent or QuickBooks for new users. If you are a sole trader looking for simplicity, one of the other options on this list may be a better fit.

HMRC offers its own free MTD-compatible software for individuals with straightforward tax affairs. It allows you to maintain basic digital records and submit your quarterly updates directly to HMRC without paying for third-party software. For people with very simple income and expenses, this can be sufficient.

However, the free HMRC software is extremely limited. There are no bank feeds, no automatic categorisation, no invoicing, and no expense receipt scanning. You will be entering everything manually, which is time-consuming and increases the risk of errors. There is also no real-time tax calculation to help you plan ahead.

For most people, the time saved by using a paid tool will outweigh the cost. We recommend the HMRC free software only if you have very few transactions (under 50 per year) and want to avoid any software costs. For everyone else, even the cheapest paid option will be a better experience.
