Enter what a director still owes the company, when the money was taken and the year end, to see the s455 tax, the day it is paid and, if the loan is repaid later, the earliest day the company can claim it back. Nothing is saved, and you don't need an account.

Repay the rest later and the company can reclaim this tax, but not before 9 months and 1 day after the end of the accounting period the repayment falls in.
The charge: a loan to a participator still owed 9 months after the end of the accounting period it was made in is taxed at the dividend upper rate of the tax year it was made in: 35.75% from 6 April 20261,3.
When it is paid: with the Corporation Tax, 9 months and 1 day after the period ends1.
Getting it back: once repaid, written off or released, claimed no earlier than 9 months and 1 day after the end of the accounting period the repayment falls in2,4. The calculator takes each accounting period as 12 months, ending on your year end.
Leave out a repayment that was followed within 30 days by new borrowing of £5,000 or more: it doesn’t count4.

Questions
What is the s455 rate?
35.75% for loans made on or after 6 April 2026, and 33.75% for loans made from 6 April 2022 to 5 April 2026. The day the money left the company decides the rate.
Can I repay the loan and borrow it straight back?
Not to avoid the tax. If £5,000 or more is repaid and lent again within 30 days, the repayment is matched to the new loan instead.
Do I get the tax back?
Yes, once the loan is repaid, written off or released, but not before 9 months and 1 day after the end of the accounting period the repayment falls in, and within 4 years.
Is there tax for the director too?
Over £10,000 owed at any time in the year is a benefit in kind, reported on the director’s Self Assessment, unless the director pays interest at the official rate.
