Going back to work raises more pay questions than people expect, and they're exactly the ones payroll often can't answer until after the fact. When does maternity pay stop and your normal salary start again? What are KIT days, and how many can you use? Does taking annual leave straight after leave change your pay? And could you ever have to repay anything?
For your full pay-by-phase figures and key dates, use the NHS Maternity Pay Calculator.
Once your maternity leave officially ends and you return to work, you revert to your normal contracted salary; your phased maternity pay (full pay, half pay, then SMP) only applies during the leave period itself.
This boundary trips a lot of people up, especially if their pay was spread evenly over 9, 10 or 12 months. If you're on a spread arrangement, the low monthly figure you've been seeing (sometimes only a couple of hundred pounds in the later months) is your spread occupational pay.
The moment you actually return to work, that stops, and you're back on your full salary from your return date, pro-rated for any partial month. You don't stay on the spread rate after you've returned.
Annual leave keeps accruing throughout your maternity leave, and many people use it to bridge their return, taking accrued leave immediately after their maternity leave officially ends. The key pay point: while you're using that annual leave, you're paid your normal full salary, not your maternity or spread rate.
So if your maternity leave ends and you go straight onto two or three weeks of carried-over annual leave before physically coming back, those weeks are paid at your normal salary — because your maternity leave has formally ended and you've "returned" for pay purposes, even though you're not yet back at your desk.
A welcome surprise: this is often good news for anyone who'd been bracing for another month on a low spread figure.
Many people arrange a phased return, going back on reduced or building-up hours rather than straight to full time. How a phased return is paid varies by Trust and by what you agree: some phased returns use accrued annual leave to top up reduced working hours to full pay, others are paid pro-rata for the hours actually worked.
Because this is arranged locally, agree the detail with your manager and payroll in advance — specifically whether the non-working portion is covered by annual leave (full pay) or unpaid (pro-rata) — so there are no surprises on your first payslip back.
Keeping in Touch (KIT) days let you do some work during your maternity leave without ending it or losing pay. You can work up to 10 KIT days during your maternity pay period, and using them doesn't bring your leave to an end or change your leave dates.
The rules are worth knowing:
KIT days are a way to stay connected and ease your eventual return, not a partial return to work — your leave and pay continue as normal around them.
If you chose to spread your occupational maternity pay over 9, 10 or 12 months, returning to work interacts with that in a way that catches people out. Spreading doesn't change your total pay or your leave length — it just smooths the occupational element into equal monthly amounts. But once you return, the spread payments stop and normal salary resumes, as above.
One related point on your first payslips back: if you kept your NHS pension running through any unpaid weeks, the contributions for that period are typically collected once you return, usually over around three months, so your early payslips back can show a larger pension deduction than normal. That's the unpaid-period contributions being recovered, not an error — we explain it in full in our NHS Maternity Pay and Your Pension guide.
If you paused a salary sacrifice arrangement before your leave (for example to protect your SMP), returning to work is usually when you'd restart it. It's worth confirming with payroll when any paused childcare voucher, cycle to work, or additional pension arrangement resumes, so it lines up with your return rather than restarting at an awkward point.

This is the area with the most misinformation, so here's the short, accurate version, with the full detail on our dedicated eligibility guide.
If you don't return to NHS employment within 15 months of the start of your maternity leave, you may have to repay the occupational (OMP) element of your maternity pay — your employer has discretion to waive this in cases of genuine hardship. The 3-month figure people often quote is the minimum return commitment, not the repayment trigger. SMP is never repayable under any circumstances, whether or not you return.
Crucially, the 15-month rule is about leaving NHS employment altogether, not about which Trust you go back to. Return to any NHS employer within 15 months — even a different Trust — and you're protected from repayment.
For the complete rules, including how this works across Trusts and how it interacts with eligibility, see our NHS Maternity Pay Eligibility & Repayment Rules guide.
The standard entitlement is 52 weeks. In exceptional circumstances, such as a sick pre-term baby or a multiple birth, the total leave period can sometimes be extended by local agreement with your employer.
This is discretionary and arranged Trust by Trust rather than an automatic right, so raise it directly with HR if your situation might qualify.
Your normal full salary resumes from the date your maternity leave officially ends and you return to work. Your phased maternity pay, or spread payments if you chose them, only apply during the leave period itself, not afterwards.
Yes. Annual leave taken immediately after your maternity leave ends is paid at your normal full salary, not your maternity or spread rate, because your maternity leave has formally ended and you've returned for pay purposes.
You can work up to 10 Keeping in Touch days during your maternity pay period without losing pay or ending your leave. Any work, even half an hour, counts as one whole day, and working beyond the 10-day limit costs you a full week's SMP for that week.
Yes. For any week containing a KIT day you must receive at least the SMP due for that week. Whether you also get your normal day's pay on top is down to local agreement with your employer, so check before agreeing to work.
You may have to repay the occupational (OMP) element only if you don't return to NHS employment within 15 months of your leave starting. SMP is never repayable. Returning to any NHS employer within 15 months, even a different trust, protects you from repayment.
If you kept your pension running through unpaid weeks, those contributions couldn't be taken at the time and are usually collected once you return, often over around three months. The larger deduction is those arrears being recovered — not a mistake.
