What do I need to do for Making Tax Digital?
A business, or an agent operating on behalf of a business, will need to:

1. Choose MTD-compliant software:
It’s best to choose an option that allows you to keep digital records and submit VAT Returns. The other option is to use software to bridge non-compatible data (like spreadsheets) to HMRC.

2. Keep digital records:
Businesses need to have started making digital records from 1st April 2022 or the beginning of their VAT period.

3. Submit VAT Returns through MTD:
Businesses need to have signed up for MTD and start submitting their VAT Return through Making Tax Digital.
Can you use a spreadsheet for Making Tax Digital?
If you want to use spreadsheets for Making Tax Digital, you’ll need to use MTD-compliant bridging software.

We don’t recommend this option as it limits the benefits of MTD which are significant for businesses: saving time and eliminating errors.
