Digital tax for companies - what’s on the horizon?

Making Tax Digital will be mandatory for corporation tax in a few years time. If a company is already following the MTD rules for VAT (MTDfV) purposes, isn’t that job done?

Digital tax for companies - what’s on the horizon?

Reporting under MTD for CT

Making Tax Digital for Corporation Tax (MTDfCT) involves keeping accounting and some other records in digital form using MTD-compatible software, plus making quarterly online reports of income and expenditure to HMRC. The quarterly filing dates will depend on a company’s accounting period. They’ll need to submit the figures within a month of the end of each quarter. HMRC will respond by providing quarterly estimates of the company’s corporation tax liability.

Who and when?

The plan is for MTDfCT to be mandatory from April 2026, with a pilot scheme from April 2024. It will apply to all UK companies and non-UK resident companies subject to UK CT. Even the smallest companies will have to comply, as will not-for-profit companies such as charities, community amateur sports clubs and societies within the charge to CT. There will be rare exceptions for companies that are unable to file digitally.


MTDfCT is different

MTDfCT will require an automated flow of data from the company to HMRC. While this is similar to MTD for VAT (MTDfV) there are differences. It's wrong to assume that because acompany complies with MTDfV, they won’t need to make changes to cope with MTDfCT. For example, if they use cash accounting for VAT, the figures for CT will differ as these must be recorded on an accruals basis.

What’s new?

MTDfCT will require  income and expenditure to be grouped under headings that will differ from those used for general bookkeeping and for MTDfV purposes. What’s more, the data must meet company law requirements.


Recording transactions

The minimum digital record for a transaction will be the date, amount and category of income and expenditure. The categories (yet to be decided by HMRC) are very unlikely to match those a company currently uses for accounting purposes. We know they’ll be similar to those used for MTD for income tax, but with additions such as income and gains from non-trading loan relationships, dividends, participator loans and directors’ benefits. Companies will have to keep some non-financial data digitally too: type of company; standard industry classification; property addresses; Senior Accounting Officer details; breakdown of group structure.

Quarterly filing will allow HMRC to track transactions in near real time. This means a need to pay special attention to compliance. HMRC will be looking closely at dividends and directors’ loan repayments, the timing of which can be critical to CT liabilities. Now is the time for companies to ensure procedures for declaring and recording these are up to scratch.

Year-end procedure

At the end of the company’s financial year the accountant still needs to make the usual adjustments to convert accounting profit or loss to that for CT purposes. The deadline for filing CT returns may be brought forward, but that’s not been decided yet.
