When an employee leaves halfway through a month, their final pay is not automatically half their monthly salary. You need to calculate earnings up to their employment end date, settle outstanding holiday, check notice arrangements and apply the correct deductions.
Start before the payroll deadline. A missing timesheet or an incorrect holiday balance can turn a straightforward departure into a disputed payslip. The aim is to produce a final payment that matches the employee’s entitlement and can be explained clearly.
Confirm the Leaving Date and Payment Period
Record the employee’s contractual employment end date, last working day and normal payday separately. These dates may differ.
Someone might finish attending work on Friday but remain employed during holiday or garden leave. Stopping their salary on their last day in the workplace could therefore underpay them.
Check which dates the next payroll covers and whether any salary has already been paid in advance. Gather:
- The employment contract and confirmed leaving arrangements.
- Approved hours, overtime and unpaid absence records.
- Holiday entitlement, holiday taken and valid carried-over leave.
- Outstanding commission, expenses and authorised repayments.
Tell whoever runs payroll about the departure promptly, especially if the employee leaves after the usual processing deadline.
Calculate Salary for the Part Month
For an hourly paid employee, calculate approved hours at the applicable rates, then account separately for paid leave and other entitlements.
For a salaried employee, check the contract’s method for calculating part-month pay. Do not assume every employer uses the same daily rate. A contract might specify calendar days, working days in the month or an annual salary divisor.
Apply the appropriate method consistently. If the contract is silent or unclear, establish the correct basis before processing rather than choosing whichever calculation produces the lowest payment.
For example, assume a five-day employee earns £31,200 annually and their contract specifies an annual salary divided by 260 for part-month calculations:
£31,200 ÷ 260 = £120 per payable working day
If 11 working days are payable, basic salary is:
11 × £120 = £1,320
This is an illustration of an agreed method, not a universal formula. Account for paid absence correctly; payable days are not always limited to days physically worked.
Reconcile Holiday Entitlement to the Leaving Date
Calculate statutory holiday accrued up to the employment end date, add any valid carried-over entitlement, then subtract leave already taken. Pay for any accrued statutory holiday that remains untaken.
Use the actual leaving date rather than automatically awarding or removing a whole month’s entitlement. Check how bank holidays are treated within the employee’s allowance.
Keep the entitlement calculation separate from the holiday pay calculation. The amount payable may need to reflect regular overtime, commission or other normal earnings. Basic salary alone will not always produce the correct holiday pay.
Irregular-hours and part-year workers have specific rules. If lawful rolled-up holiday pay has already been paid, reconcile those payments rather than automatically adding another holiday payment.
Where the contract provides holiday above the statutory minimum, check its rules for that additional allowance.
If the employee has taken more holiday than they accrued, a deduction from final wages requires agreement in the contract or in writing beforehand. A negative holiday balance does not, by itself, authorise recovery.
Separate Notice Pay from Other Earnings
Confirm whether the employee will work their notice, remain employed on garden leave or receive payment in lieu of notice.
An employee working their notice should receive their normal contractual pay for that work. During garden leave, employment continues, so salary, contractual benefits and holiday accrual generally continue until termination.
Payment in lieu of notice ends employment without the employee working the relevant notice period. Check the contractual or agreed entitlement and show the payment separately in payroll.
If sickness or family leave overlaps with notice, review the notice-pay rules before accepting the usual absence payment. Entitlement can depend on the reason for leaving and the relationship between statutory and contractual notice.
Also check overtime, commission and bonuses against the relevant terms. Record any payment that becomes due later, including who will approve it and when it will be processed.
Check Every Deduction Before Applying It
PAYE, National Insurance and applicable student loan deductions still need to be calculated. Check pension contributions against the scheme’s rules and the earnings included in the final payment.
For other deductions, establish the legal or contractual basis first. Training costs, equipment charges and outstanding loans should not simply be removed because the employee is leaving.
Recovery of a genuine wage overpayment is generally permitted, but verify the amount and explain the calculation. Other deductions may require a contractual clause or prior written agreement. Minimum wage rules can also affect what is recoverable through payroll.
Do not withhold all final wages because a laptop has not been returned. Address the property issue separately unless a lawful deduction applies.
Review the Gross Pay Before Calculating Take-Home Pay
Using the earlier example, suppose the employee also has three untaken holiday days payable at £120 each and £90 of approved overtime:
| Final pay item | Amount |
| Salary for 11 payable working days | £1,320 |
| Three untaken holiday days | £360 |
| Approved overtime | £90 |
| Total gross pay | £1,770 |
The holiday rate here is an assumption for this example and must be checked independently in a real calculation.
The £1,770 is gross pay, not the bank transfer amount. Process it through payroll using the applicable tax code and deduction settings.
Ordinary wages, holiday pay and payment in lieu of notice are normally subject to tax and National Insurance. They do not become tax-free simply because they appear in a leaving payment.
Complete Payroll Reporting and the Employee’s Documents
Final pay should normally arrive on the employee’s usual payday. Leaving mid-month does not automatically require immediate payment.
Provide an itemised payslip showing each payment and deduction. A short explanation of the salary calculation and holiday adjustment can prevent avoidable questions.
For a straightforward departure within the same tax year, include the leaving date in the payroll record when processing the final payment. Submit the Full Payment Submission to HMRC on or before payday, unless a permitted exception applies, and issue the P45.
Keep the approved calculation and supporting records together. Interface Accountants’ payroll services include payroll processing, payslips and RTI submissions, helping employers coordinate these final steps.
Frequently Asked Questions
1. Can final pay wait until the next normal payday?
Usually, yes. Confirm the contractual payday and tell the employee when payment will arrive.
2. Should unused holiday be rounded down to whole days?
Do not automatically discard fractional entitlement. Calculate and pay the outstanding statutory balance accurately.
3. Does leaving immediately remove the right to earned wages?
No. Wages already earned and accrued statutory holiday remain payable. Review notice disputes and any proposed deductions separately.
4. What if a bonus is paid after the P45?
Apply HMRC’s payment-after-leaving procedure, including the appropriate non-cumulative tax code and FPS indicator. Provide written payment details; do not issue another P45.
5. Does statutory maternity pay stop when employment ends?
Not necessarily. An existing entitlement can continue after employment ends, so check the remaining payment obligation before closing payroll.
Make the Final Payment Easy to Explain
Accurate final pay starts with confirmed dates and clear records. Calculate salary, holiday and notice separately, verify deductions, then match the payslip, payment and payroll submission.
For future departures, use a standard leaver checklist with one person responsible for approving the figures. Giving your payroll accountant complete information before processing is far easier than correcting an underpayment after the employee has left.
