A director's loan is less a transaction than a running position, and understanding it means following it through a full accounting cycle rather than looking at a single payment. This page walks the sequence: the money moves, the account records it, the year end takes a photograph, and two deadlines afterwards decide what anybody pays.
Step one: the money moves and the account records it
The company pays a personal bill, or the director draws cash the company owes them nothing for. The bookkeeping posts it to the director's loan account rather than to an expense, because it is neither a company cost nor pay. Nothing is reportable at this point and no tax arises; the account simply carries a balance one way or the other, and it can cross from credit to debit and back several times in a year.
Step two: the year end takes a photograph
Only the balance on the last day of the accounting period matters for the corporation tax charge. A director who was £40,000 overdrawn in June and level by 31 March has nothing to report. A director who was level all year and drew £5,000 on 30 March reports £5,000. This is why the timing of a dividend declaration, or a repayment from personal funds, is worth thinking about in the last month of the year rather than the first month of the next one.
Step three: nine months, and then the charge
If the year-end balance is still outstanding nine months and one day after the period end, the company pays 33.75% of it. Note that this is the same date the company's own corporation tax falls due, which is deliberate and convenient: one deadline, both liabilities. Repay before it and nothing is due. Repay after it and the company can reclaim the tax, but not until the loan is permanently gone, and reclaims are made through the return rather than by writing in.
Step four: the parallel personal question
Independently of all of the above, if the loan exceeded £10,000 at any point in the tax year it is a benefit in kind on the director unless the company charged interest at HMRC's official rate. That is a P11D matter with its own deadline in July, and it applies even where the loan was cleared before the year end and no corporation tax charge ever arose.
Questions people ask about how does a directors loan work
How long can a director's loan stay outstanding?
Indefinitely, but the company pays 33.75% of the balance if it is still outstanding nine months and one day after the end of the accounting period, and that tax is only recoverable once the loan is permanently repaid.
Does it matter when in the year I take the loan?
For the corporation tax charge, only the balance on the last day of the accounting period counts. For the benefit in kind, the peak balance at any point in the tax year is what matters.
Can the loan be cleared with a dividend?
Yes, where the company has distributable reserves to declare a dividend from. The dividend clears the loan account and is taxed on the director at dividend rates, which is usually cheaper than leaving the s455 charge in place.
