Is income in my company accounts always taxable? Corporation Tax and box 205 explained

Income in company accounts is not automatically taxable in the same amount or under the same heading. The tax computation explains the differences between the accounts and the CT600.

Keep two questions separate

First, what figures belong in the prepared accounts? Second, how are those figures treated for Corporation Tax? Removing an accounts credit simply to reduce the tax answer can make the accounts wrong. A tax adjustment lets you explain the difference without deleting the credit.

Where box 205 fits

Box 205 is for taxable income without another heading, including non-exempt UK distributions. It is not a catch-all for every receipt. HMRC's CT600 box 205 guidance sets out its scope. Turnover, interest and property income have their own categories.

A round-number example

Suppose the accounts include £4,000 in an other-income category. The company's adopted treatment excludes £3,000 from taxable income. The computation explains that adjustment, leaving £1,000 taxable. With no taxable UK distributions, the box 205 amount is £1,000. This example assumes the exclusion is appropriate. The figures alone cannot establish that.

Three mistakes to avoid

• Deleting the full accounts amount when only its tax treatment differs.
• Entering the exclusion as an expense, disallowable cost or unrelated loss.
• Assuming words such as unrealised or exchange gain determine the tax result.

Our Corporation Tax calculation guide shows how the adjustment fits alongside other additions and deductions.
