Advance Corporation Tax

Definition and meaning of Advance Corporation Tax (ACT) in the context of the UK taxation system and its impact on dividend distribution and corporate tax liability.
On this page

In one sentence

Advance Corporation Tax (ACT) was a UK tax mechanism (abolished in 1999) under which companies paid tax when distributing dividends, with the payment treated as an advance credit against their mainstream corporation tax liability.

How it worked (conceptually)

Under the UK’s imputation-style arrangements at the time, dividend payments were closely linked to income-tax credits for shareholders. ACT functioned as a “payment at distribution” by the company that could (subject to rules and timing) be offset against corporation tax due on profits.

A simplified calculation

Let $D$ be the dividend paid and $\tau_{ACT}$ be the ACT rate. Then the ACT payment (in simplified form) was:

\[ ACT = \tau_{ACT}\,D \]

Let $CT$ be mainstream corporation tax due on profits for a period and $CT^{gross}$ the corporation tax before offsetting ACT. A stylized way to express the offset is:

\[ CT = \max\left(CT^{gross} - ACT,\;0\right) \]

The details depended on the company’s profit position, timing, and specific tax rules; the key economic point is that ACT shifted some tax payment forward to the moment dividends were paid.

A simple flow view

    flowchart TD
	  P["Company profits"] --> CTG["Mainstream corporation tax (gross)"]
	  P --> D["Dividend declared / paid"]
	  D --> ACT["ACT paid at distribution"]
	  ACT --> Credit["Credit against corporation tax (subject to rules)"]
	  CTG --> NetCT["Corporation tax payable (net)"]
	  Credit --> NetCT

Why it mattered (economic incentives)

ACT could affect:

  • dividend policy: a cash-flow cost at distribution could tilt firms toward retained earnings, especially when profits were low or volatile.
  • investment and financing: firms with limited internal funds may be more sensitive to taxes that reduce distributable cash.
  • shareholder incidence: the overall burden depends on how dividend taxation and credits are designed and who holds shares (individuals, pension funds, foreign investors).

Why it was abolished

ACT was removed as part of broader reforms to simplify corporate/shareholder taxation and to change how dividend tax credits worked across investor types. In applied terms, the system moved away from a tax-at-distribution mechanism toward alternative arrangements for taxing dividends and corporate profits.

  • Dividend: A portion of a company’s earnings distributed to shareholders.
  • Corporation Tax: A tax imposed on a company’s profits.
  • Shareholder: An individual or entity that owns shares in a corporation.
  • Retained Earnings: Profits not distributed as dividends, kept by the company for reinvestment.
  • Imputation System: A tax system linking corporate and shareholder taxes, often via dividend tax credits.
