How Making Tax Digital (MTD) Works in Practice
Step by Step
For MTD for VAT, you use compatible software to record your sales and purchases throughout the quarter. The software must maintain digital records that link directly to the VAT return submission. At the end of each quarter, you review the figures, make any adjustments, and submit the return through the software's API connection to HMRC. You cannot log into the HMRC portal and type in the nine boxes manually.
Digital links are a key requirement. If you use multiple systems (for example, a spreadsheet for some calculations and accounting software for submission), the data must flow between them digitally, not by being manually retyped. Copy-and-paste is not considered a digital link. This means your entire record-to-return process must be connected electronically.
For MTD for ITSA (from April 2026), qualifying individuals must submit a quarterly update within one month of the end of each quarter (quarters ending 5 July, 5 October, 5 January, and 5 April). These updates summarise income and expenses for the quarter. An end-of-period statement is submitted after the end of the tax year, and a final declaration replaces the current Self Assessment tax return.
Practical Tips
Common Mistakes to Avoid
- Using spreadsheets to keep VAT records without a digital link to MTD-compatible submission software, which breaches the digital record-keeping requirement
- Manually entering VAT return figures into the HMRC online portal instead of submitting through MTD-compatible software
- Assuming MTD only applies to large businesses when MTD for VAT applies to all VAT-registered businesses regardless of size
- Not checking whether personal income from self-employment or property will bring you into scope for MTD for ITSA from April 2026
