Mainstream Corporation Tax (MCT)

What is Mainstream Corporation Tax (MCT)?

Mainstream Corporation Tax (MCT) refers to the tax liability of companies in the United Kingdom for a given accounting period, after deducting any Advance Corporation Tax (ACT) that had been paid. MCT played an essential role in ensuring that companies calculated their total tax liability accurately. However, this system element was rendered obsolete when ACT was abolished in 1999.

Background

Under the ACT system, companies had to pay tax when they distributed dividends. These advance payments were then set off against the MCT to determine the final corporation tax due. After 1999, the UK tax system simplified by removing ACT, making MCT calculation a straightforward assessment of profit.

Examples

Corporate Tax Calculation Pre-1999: A company earned £1,000,000 in taxable profits and paid £100,000 in dividends. If the ACT applied was £30,000, this amount would be subtracted from the total tax due to compute the MCT.
Post-1999 Simplified Tax Calculation: After ACT’s abolition, a company with £1,000,000 in taxable profits simply calculates its tax liability based on the prevailing corporation tax rate without needing to account for any deducted advance payments.

Q3: What took the place of Mainstream Corporation Tax after 1999? A: The corporation tax system continued, but without the component of offsetting ACT, simplifying profit-based tax calculations for companies.
