Bridging Software for MTD: What It Is and Do You Need It?
Bridging software lets you keep using your existing spreadsheets while still meeting your MTD for Income Tax obligations. Rather than switching to a new bookkeeping system, you upload your spreadsheet data and the software handles the digital connection to HMRC. This guide explains how bridging software works, who it suits, and how it differs from full MTD tracking software.What Is Bridging Software?
MTD for Income Tax requires all records to be kept digitally and submitted to HMRC through compatible software. But compatible software does not have to mean a fully automated bookkeeping platform -- for many taxpayers, a simpler option exists.
Bridging software acts as the link between your existing digital records (typically a spreadsheet) and HMRC's MTD system. You continue to maintain your income and expense records however you prefer -- in Excel, Google Sheets, or any other digital format -- and when a quarterly update is due, you upload your spreadsheet to the bridging tool, which formats and transmits the data to HMRC on your behalf.
The result: you stay MTD-compliant without changing the way you work.
What Is a Digital Link?
HMRC requires that the data flowing from your records to HMRC must be connected by a "digital link" at every step. A digital link means the data must transfer electronically -- you cannot, for example, type your spreadsheet totals manually into a separate submission form.
Bridging software satisfies this requirement automatically. When you upload your spreadsheet, the software reads the data electronically and passes it directly to HMRC's API. There is no manual re-keying involved, which is exactly what HMRC's digital link rules require.
Copying and pasting figures from one cell to another within the same spreadsheet is generally acceptable. What is not acceptable is breaking the digital chain by transcribing figures by hand into a different system.
Who Should Use Bridging Software?
Bridging software is a good fit if:
- You already have a well-organised spreadsheet system for tracking income and expenses and do not want to replace it
- You are comfortable maintaining your own records and just need a way to submit them to HMRC
- Your tax affairs are relatively straightforward -- one or two income sources, no complex bookkeeping requirements
- You want the lowest-cost route to MTD compliance
It is less suitable if:
- You want your records maintained automatically (bank feeds, receipt scanning, automatic categorisation)
- You have multiple businesses or complex allowable expense categories that benefit from dedicated tracking tools
- You are starting from scratch with no existing spreadsheet system
How Taxd's Bridging Software Works
Taxd offers HMRC-recognised bridging software as part of its MTD product range. The process is straightforward:
- Download the Taxd MTD template -- a ready-to-use spreadsheet formatted to HMRC's required structure, with columns for income and expense categories by quarter
- Complete the spreadsheet with your income and expenses for the quarter
- Upload it to Taxd -- drag and drop your completed spreadsheet into the Taxd platform
- Review and submit -- Taxd reads the data, shows you a summary to confirm, and submits your quarterly update directly to HMRC
You keep full ownership of your data. Your records stay in the spreadsheet. Taxd handles the technical transmission.
Bridging Software vs Smart Tracking Software: Which Is Right for You?
| Bridging software | Smart tracking software | |
|---|---|---|
| You maintain your own records | Yes | No -- software does it for you |
| Bank account connection | No | Yes (automatic transaction import) |
| Receipt capture | No | Yes (via app or upload) |
| Automatic categorisation | No | Yes |
| Suitable for | Organised spreadsheet users | Anyone wanting a hands-off approach |
| Best for | Landlords and freelancers with existing systems | Sole traders with regular transactions |
| Taxd option | Bridging (Spreadsheet) Software | Smart Tracking via Keptd |
Both options fully meet HMRC's MTD requirements. The right choice depends on how you already work and how much automation you want.
Does Using a Spreadsheet Still Count as Digital Record-Keeping?
Yes -- provided the spreadsheet meets HMRC's minimum standards. Your digital records must capture the date, category, and amount for each transaction. A well-structured spreadsheet does this. What is not acceptable under MTD is keeping paper records only, or keeping records in a format that cannot be digitally linked to submission software.
If you are currently using a manual cashbook, paper receipts folder, or a bank statement as your only record, you will need to move to a digital format before you can use bridging software.
Common Questions
Can I use any spreadsheet with bridging software, or does it need a specific format? Taxd provides a template that is already formatted correctly for HMRC submission. You can use your own spreadsheet if it captures the required data fields, but using the template is the quickest way to get started.
Is bridging software cheaper than full MTD software? Yes, typically. Because it does not include bank feeds or automated bookkeeping, bridging software is offered at a lower price point. Taxd's bridging tier is available from £6 per month.
Can I switch from bridging to smart tracking software during the year? Yes. If you decide mid-year that you want more automation, you can migrate to Keptd or another tracking solution. Your historical quarterly submissions are not affected.
What if my spreadsheet has errors? Taxd validates your data on upload and flags any issues before submission. You can correct the spreadsheet and re-upload before confirming the submission to HMRC.
