User Guide for CHM Bridging Software

CHM Bridging Software will file VAT returns under Making Tax Digital.

The software can only be used after you have signed up to MTD, which you can join through your current HMRC Government Gateway account.

You are a few moments away from being able to submit your VAT return via Microsoft Excel using our Bridging Tool.

This user guide will detail how to setup and use the Bridging Tool to file your VAT returns from Excel. All your VAT returns will be submitted through your Bridging Tool and will require linking each time for every submission. For ease of use we recommend that you save your Bridging Tool to your desktop.

If you wish to embed the Bridging Tool within your own spreadsheet workbook, you will also need to follow the instructions on “How to Embed the Bridging Tool into my own Workbook” before attempting to file your VAT return.
