Can we deduct a retention bonus before we pay it?
Yes, but only if you pay it soon enough. You can charge the bonus as a cost in the year you decide on it, and that accrual is deductible in that year, provided the bonus is actually paid within nine months of the end of your accounting period. Pay it inside that window and nothing moves. Pay it after, and the deduction is taken out of the accrual year and allowed instead in the year the money leaves, so the relief is delayed rather than denied. The rule does not care whether you call it a bonus, an incentive or a retention payment; what matters is the date it is paid against the date your year ends.
For a care agency with fifteen or more carers, this usually comes up in one of two ways: a thank-you bonus you accrue at the year end to reward a hard year, or a structured retention payment designed to keep people through a difficult patch. The first is easy to get right once you know the date; the second often cannot meet it by design. Our care agency accounting team sets the payment date deliberately, so the deduction lands in the year that actually helps your tax position. If your question is really about the broader cost of getting the year end done, our guide to year-end accounts costs for a domiciliary care agency covers that separately; this page is only about the timing of the bonus deduction.
What is the nine month rule for staff bonuses?
The nine month rule is the test that decides which year a bonus is deductible in. It lives in section 1288 of the Corporation Tax Act 2009, backed by HMRC's guidance at BIM47130 on unpaid remuneration. Where an amount is charged in a company's accounts for employees' pay and would otherwise be deductible, no deduction is allowed for that period unless the pay is made within nine months after the end of the period of account. If it is paid after that, section 1288(2) allows the deduction in the later period in which it is actually paid, and if it is never paid at all, section 1288(3) denies the deduction entirely.
There is a neat way to remember the date. Corporation tax for a company with profits up to 1.5 million pounds is due nine months and one day after the accounting period ends, so the pay-by date for the bonus deduction sits exactly one day before your tax payment date. If your year ends on 31 March, the bonus needs to be paid by 31 December to stay in that year, and the tax is due on 1 January. The timeline below shows how the deduction follows the payment date, and our tax planning and advisory team maps it onto your real year end before the accounts are signed off.
Notice that the cash basis sits outside all of this. The unpaid remuneration rule applies to businesses that prepare their accounts on the normal accruals basis, which is every care agency run through a limited company. A very small unincorporated business using the cash basis would deduct wages when paid in any case, so the nine month test never bites there. If you are a limited company, which almost all agencies with payroll are, assume the rule applies to every bonus you accrue.
When does HMRC treat the bonus as paid?
Paid means paid, not promised, and the definition is stricter than owners expect. HMRC treats remuneration as paid when it is treated as received by the employee for the employment income charge, broadly the point at which the money is handed over or made available to them. BIM47130 is explicit that operating PAYE on the bonus is sufficient evidence that it has been paid, so the cleanest proof is simply running it through a pay run with tax and National Insurance deducted. A board minute resolving to award a bonus, or a figure sitting in the accounts as a provision, is not payment and does not start the clock.
This matters most where a bonus is credited to a director's loan account rather than paid in cash. Crediting the account so the director can draw on it can count as payment, but only if it genuinely makes the money available and is reported correctly; a bookkeeping entry made purely to secure a deduction, with the cash never actually accessible, will not stand up. The safe route for a care agency is to pay the bonus through payroll on or before the nine month date and keep the payroll record, so the date paid is never in doubt.
How much of the bonus can we deduct this year?
All of it, part of it, or none of it, depending entirely on how much is paid before the nine month date. The accrual sets the amount; the payment date sets the year. Take a care agency with a 31 March year end that accrues a 40,000 pound retention pot for its carers. It pays 30,000 pounds through the December payroll, comfortably inside the nine months, and holds back 10,000 pounds that is only paid the following February, after the cut-off. The split below shows how that one pot lands in two different tax years.
So the deduction is not an all-or-nothing switch. The 30,000 pounds paid in time is deductible in the year you accrued it; the 10,000 pounds paid late is deductible in the following year instead. That is useful to know in both directions. If this year's profit is high, you want as much of the bonus paid before the date as cash allows. If next year's profit looks higher, deliberately paying a slice after the cut-off can move that relief to where it saves more tax. The table sets out the three outcomes in full.
The same accrued bonus, three payment timings, and when the deduction actually lands:
| When the bonus is paid | Deductible in the accrual year? | When you get the deduction |
|---|---|---|
| Within nine months of the year end | Yes, in full | The year you accrued it |
| After the nine month cut-off | No | The year you actually pay it |
| Still unpaid when the return is filed | No | Not until paid, and lost entirely if never paid |
What if the bonus only pays out if staff stay?
This is where a true retention bonus parts company with an ordinary year-end bonus. A retention scheme often promises a payment only if the carer is still employed in, say, a year or two, so at the year end you hold a provision for a cost that is not yet payable. HMRC's guidance at BIM47135 confirms that such a provision is still an amount charged in the accounts for employee pay, using the very example of a bonus payable only if the employee is still working for the employer years later. So the nine month rule still applies to it.
The consequence is simple once you see it. Because a long term retention bonus will not be paid within nine months of the year you book the provision, the deduction cannot be taken in that year. It waits until the accounting period in which the bonus is actually paid, which may be two or three years down the line. That is not a problem, but it is a planning point: you get the staffing benefit now and the tax relief later, and your management accounts should show the provision as a cost without assuming it reduces this year's tax bill. The statutory home for all of this is sections 1288 and 1289 CTA 2009, and it is worth having an accountant confirm which year each tranche falls in before the figures are fixed.
Before you file: pin the deduction to the right year
Our position, after running company tax for care agencies across London, is that the bonus deduction should never be left to chance. Decide which year you want the relief in, then set the payment date to match, rather than discovering after the fact that the cash went out a few days too late. Where cash allows and this year's profit is high, pay in time. Where next year looks tighter for tax, a deliberate slice paid after the cut-off can be the better call. Either way, the decision is yours to make on purpose, and the checklist below is the sequence we work through before a client's return is filed.
Retention bonus deduction timing checklist
Run this before you fix the figures. It is the order we use for care clients timing a bonus deduction.
- Note your accounting year end and count nine months forward; that is your pay-by date.
- Check it against your corporation tax due date, which is nine months and one day after the year end, so you do not miss it by a day.
- Decide which tax year you actually want the deduction in, this year or next.
- Set the payment date to match, and confirm the cash is there to pay by that date.
- Run the bonus through payroll so it is treated as paid, operating PAYE and employer National Insurance.
- For a long term retention bonus, book the provision but expect the deduction only in the year you pay it.
- Keep the board minute, the payroll record and the bank payment together as proof of the date paid.
A bonus decision like this usually lands at the busiest time of the year, right as the accounts are being pulled together and payroll is already stretched. This is exactly the kind of call a specialist care agency finance team takes off your desk: we confirm the pay-by date, time the payment to the year that helps your tax, and make sure it goes through payroll correctly so the deduction is never in doubt. It is one part of the wider outsourced finance function we run for agencies once payroll, funding and tax all need to move together.
