If you are currently tracking income and expenses in a spreadsheet, MTD bridging software is the cheapest and least disruptive way to become compliant. These tools link your spreadsheet directly to HMRC, so you can submit quarterly updates without changing how you work.
What is MTD bridging software?
Bridging software acts as a bridge between your existing spreadsheet and HMRC’s MTD systems. Instead of re-keying your data into a new accounting package, you keep using your spreadsheet and the bridging tool handles the digital submission to HMRC. It is the most popular approach for UK sole traders: 123 Sheets alone handled 33% of all HMRC quarterly submissions in Q3 2024/25.
