Making Tax Digital: Choosing HMRC Compatible Software

For Making Tax Digital (MTD), you must use functional compatible software that links to HMRC. This article outlines your compliance options, including all-in-one software suites and spreadsheet combinations, alongside mandatory deadlines and strict digital link requirements.

To comply with the Making Tax Digital rules, you need functional compatible software that keeps records, sends updates, and files your final tax return. This requirement can be met either by using a fully integrated cloud accounting program or by pairing traditional spreadsheets with dedicated bridging software. Both methods must establish a direct API connection to HMRC to transmit your data securely.

Key Takeaways: MTD Software at a Glance

1. Functional compatible software must be used to record transactions, submit quarterly updates, and file final decorations.
2. The all-in-one software route uses a single package like Xero or QuickBooks to handle all record-keeping and submissions.
3. The spreadsheet route allows you to keep records in Microsoft Excel or Google Sheets, but requires bridging software to transmit data.
4. Manual data copying, typing, or cutting and pasting between systems is strictly illegal under the HMRC rules on digital links.
5. Mandatory implementation begins on 6 April 2026 for businesses and landlords with qualifying income above £50,000.

What HMRC software do I need to comply with MTD?

You do not need to use a specific HMRC-branded program to comply; instead, you must select commercial software that HMRC has approved as functional compatible software.

Functional compatible software refers to any software program or suite that can record and preserve digital records, prepare quarterly updates, and exchange data with HMRC systems via an Application Programming Interface (API). There are two main pathways you can choose: a single comprehensive software package that manages everything, or a combination of spreadsheets linked to HMRC through specialized bridging tools.

Option 1: Using full MTD accounting software

Full accounting software acts as an all-in-one system to maintain your businesses books and handle tax submissions in one location.

By adopting a complete platform, you eliminate the need to transfer files between separate programs. Popular HMRC-compatible options include cloud solutions such as Xero, QuickBooks, and FreeAgent, as well as desktop-focused software like Sage, TaxCalc, and Andica.

1. Verify the software supports your business structure, especially if you are a landlord or a sole trader.
2. Check if your bank offers a compatible program for free, which is common with platforms like FreeAgent.
3. Confirm the application is capable of completing the end-of-year final declaration process before you buy.
4. Use the official HMRC software finder tool to check compatibility for your specific tax circumstances.

Option 2: Can I still use spreadsheets for MTD?

You can keep your digital records in MS Excel or Google Sheets, but you cannot submit them directly to HMRC without extra bridging software.

HMRC recognises spreadsheets as a valid digital record-keeping medium. However, because standard spreadsheets lack the API technology required to communicate with HMRC systems, you must use bridging software like VitalTax, 123 Sheets, MTD Bridge, or Absolute Excel Income Tax Filer. This bridging program reads the data directly from your worksheet and transmits it securely to HMRC.

The strict HMRC rule on digital links

A digital link is an electronic transfer of data between programs where human manual intervention is completely removed.

Under Regulations 8, 9, and 15 of the Value Added Tax Regulations, HMRC defines strict guidelines on how data must flow. If you use multiple programs, they must be digitally linked. Manually typing out or copying and pasting figures from a spreadsheet into your submission portal breaks this digital chain and makes you non-compliant.

When does MTD for Income Tax apply to me?

The date you must join Making Tax Digital for Income Tax depends entirely on your total gross income from sole trading and property rentals.

Your qualifying income is calculated by combining all of your gross business receipts and gross rental revenues. You must comply by the following statutory deadlines based on these specific thresholds.

How to choose between full software and bridging links

Selecting the right approach depends on whether you prefer a modern integrated bookkeeping system or wish to keep your familiar spreadsheet setup.

Full cloud accounting programs automate bank feeds and reconcile accounts instantly, saving time but carrying monthly subscription costs. Meanwhile, bridging links let you keep your old templates and spreadsheets for low fees, though you must still manually input and maintain complex spreadsheet formulas.

Can I use Excel for Making Tax Digital free of charge?

While Microsoft Excel itself is not free, you can use your existing spreadsheet to record your transactions. However, to file returns with HMRC you must pay for a compatible bridging link software, as spreadsheets alone cannot transmit tax data securely.

Do I have to pay for HMRC bridging software?

Yes, nearly all commercial bridging software carries a fee, though these solutions are usually much cheaper than full-featured cloud accounting platforms. HMRC does not provide free bridging software directly to the public.

What happens if I copy and paste data under MTD rules?

Copying and pasting values breaks the electronic connection required by law. Doing this will make your workflow non-compliant with HMRC Regulations 8, 9, and 15, exposing your business to potential penalties for poor record-keeping.

Does my accountant's software count for my MTD submission?

Yes, your accountant can submit filings on your behalf using their professional software. However, you are still legally required to maintain your own digital business transactions through compliant methods on your end.
