The CT600A is the supplementary page to the Company Tax Return for loans a close company has made to its participators, usually an overdrawn director's loan account. It is where the section 455 charge on those loans is declared and where relief is claimed when they are repaid.
Who completes it
A close company that was owed money in the period by a participator or one of their associates, where the amount was a loan or advance and not pay or a dividend. A participator is usually a director-shareholder. Box 95 on the CT600 is ticked to say the page is attached.
What it asks for
- Part 1: each loan made in the period and still outstanding at the end of it, with the name of the participator, and the tax chargeable (box A20).
- Part 2: relief for amounts repaid, released or written off within nine months of the end of the period.
- Part 3: relief now due for earlier loans that were repaid, released or written off later.
- The totals: loans outstanding at the end of the period (A75) and the tax payable (A80), which goes to box 480 on the CT600.
The charge is 35.75% of the loan outstanding at the end of the period, or 33.75% for loans made between 6 April 2022 and 5 April 2026. It is refunded once the loan is repaid, released or written off.
