MTD Software Options Explained: Which Type is Right for You?

The Three Main Types of MTD Software

When it comes to MTD compliance, there is no single approach that suits everyone. HMRC recognises three broad categories of compatible software: full accounting software, bridging software, and HMRC's own free tools. The right choice depends on how you currently manage your records, your budget, and how hands-on you want to be with your finances.

All three approaches can satisfy your MTD obligations, but they differ significantly in cost, features, and the amount of manual work involved. Understanding the differences will help you make a more informed decision.

Full Accounting Software (Xero, QuickBooks, Sage, FreeAgent)

Full accounting software handles everything from recording transactions and invoicing clients to submitting your quarterly updates and end of year statements to HMRC. It is the most comprehensive option and, for most sole traders who do not use spreadsheets, the most practical.

The main providers are:

• Xero — Feature-rich with 800+ integrations. Best for growing businesses that need powerful reporting and bank feeds.
• QuickBooks — Competitive pricing with a Self-Employed plan from £8/month. Good for straightforward sole trader finances.
• Sage — UK-based with UK support. Sage Accounting Start is tailored for sole traders needing simple MTD compliance.
• FreeAgent — Purpose-built for freelancers and sole traders. Free for NatWest and RBS business banking customers.

Bridging Software: For Spreadsheet Users

Bridging software is designed for sole traders who want to continue using spreadsheets — such as Excel or Google Sheets — for their record-keeping, but still need to submit their quarterly updates to HMRC digitally. The bridging tool sits between your spreadsheet and HMRC, reading the figures from your designated cells and submitting them in the correct MTD format.

Bridging software tends to be cheaper than full accounting packages, often priced at under £10 per month or as a one-off annual fee. However, it does not replace your record-keeping process — you still need to maintain your spreadsheets accurately. Well-known bridging tools include Absolute Bridging and Cirrostratus MTD Bridge.

HMRC's Own Free Tools

HMRC provides some free tools for MTD compliance, but these are primarily aimed at the simplest cases — typically those with a very small number of transactions and no need for invoicing, reporting, or bank feeds. They are functional but basic, and HMRC has indicated these tools are intended as a last resort rather than a recommended primary solution.

If cost is your primary concern, it is worth comparing the HMRC tools against the cheapest commercial options before committing. A low-cost full accounting package may actually save you time and reduce errors compared to using a free but limited tool.

How to Choose the Right Option

The right MTD software depends on a handful of key factors: whether you currently use spreadsheets (and want to continue), your budget, how much time you want to spend on bookkeeping, and whether you need additional features like invoicing or bank feeds. If you are comfortable with technology and want an all-in-one solution, full accounting software is usually the best fit.

If you are committed to spreadsheets and your finances are straightforward, bridging software may be sufficient and cheaper. HMRC's free tools are worth considering if your finances are very simple and cost is the overriding concern.

Our Top Recommendations

For most sole traders, we recommend starting with full accounting software. FreeAgent is our top pick for freelancers and those who bank with NatWest or RBS, as it may be free. QuickBooks offers the most competitive pricing for budget-conscious users. FreeAgent and Xero both excel on ease of use, and Sage is the strongest choice for those wanting UK-based customer support.
