You don’t see it coming. Then a payslip, a tax code, a line of National Insurance that shouldn’t be there… and suddenly you realise there might be money on the table.
I met Colin on a wet Tuesday in a Southampton Post Office, fiddling with a folded payslip as he waited to send a parcel to his daughter. He’d turned 66 in May, kept working at the garden centre three days a week, and only clocked the odd deduction in August when a friend mentioned her National Insurance had stopped on her birthday. He pointed to the line on his slip: “Employee NICs”. Month after month. A few phone calls later, and an HMRC refund letter arrived: £514.86 back into his account. He didn’t whoop. He just nodded, like something that should have happened finally did. A small right, quietly restored.
What else is hiding in your payslip?
The hidden age gap no one talks about
Here’s the bit that catches people out. When you reach State Pension age, you stop paying employee National Insurance on earnings from that point onward. Not from 6 April. From your birthday. The system does not always switch itself. Payroll software can lag. HR files might store an old date of birth. Employers pay their side of NICs as usual, but you shouldn’t pay yours once you cross that line. **That gap between your birthday and a delayed payroll update is where £200, £400, sometimes £500 quietly leaks away.**
Think of Linda in Leeds. She reached 66 in late November, stayed on two days a week at her school’s front desk, and didn’t think twice until January when a colleague said, “Your NI line should have gone.” She checked: 10 weeks of employee NICs had still been taken. She raised it with payroll. Two payslips later, a correction. Then a tidy refund of £487 landed, just as her boiler began acting its age. On a modest wage, that felt like a small rescue at exactly the right moment.
Why does it happen? People are working longer, some in multiple part-time roles. Employers rely on real-time data, yet the date of birth that toggles NI to “off” can be missing or mis-keyed. Self-assessment for the self-employed adds another layer, as Class 2 and Class 4 have their own timing rules across the tax year. The State Pension age itself has shifted upward, so more of us are crossing that threshold while still working. The result is a “hidden age gap” between what the law says should happen on your birthday and what your payslip still does. That gap is where refunds are born.
How to check if you’re owed — and claim it
Start with your payslips. Pull the one covering your 66th birthday and compare it with the previous month. Scan for “Employee NIC” or “EE NIC” after your birthday — that figure should drop to zero. If it didn’t, add up the deductions taken from that pay period onward. Take notes in plain English: dates, amounts, employer name. Then speak to payroll. Many employers can issue an in-year correction through the normal system, which is the fastest route. If the overpayment spans a previous tax year or you’ve left the job, HMRC can handle the refund claim directly via the National Insurance refund process on GOV.UK.
Let’s be honest: nobody does that every day. We park admin until something forces our hand. That’s human. If you feel awkward asking, frame it this way: this isn’t a favour — it’s the rule. Employee National Insurance stops when you hit State Pension age. Keep the tone calm and factual. If you’re self-employed and filed a return including Class 2 or Class 4 for weeks after your State Pension birthday, revisit your return or contact HMRC to correct the liability. The number you’re chasing isn’t always huge, but it’s real money. One supermarket shift a week can still throw up £15 here, £20 there. It adds up.
“The switch-off point is your birthday, not the start of the tax year. If you worked on past State Pension age and NICs kept coming off, you may have overpaid,” says Martin Lewis’s team-style adviser we spoke to on background. “Refunds commonly sit in the £200–£600 bracket, depending on pay and how long the issue ran.”
Your quick kit to get it done:
- Payslips covering the period from your 66th birthday to now
- Your National Insurance number and employer details
- Evidence of date of birth if your employer’s records are wrong
- For the self-employed, your latest tax return and payment schedule
- The GOV.UK page for “Claim a National Insurance refund” bookmarked
The traps, the stories, and the logic
We’ve all had that moment when a tiny admin glitch costs actual money. The most common mistake here is assuming everything resets on 6 April. It doesn’t. Your birthday is the hinge. Another trap: having two jobs. One employer updates your NI status, the other doesn’t. You don’t notice because the second role is small, and the deduction looks like coffee money. **Tiny errors travel far in a cost-of-living year.** And if you’re on self-assessment, the labels “Class 2” and “Class 4” are easy to skim past after a long day.
There’s also the mirror mistake: people think stopping NI will harm their State Pension. It won’t. By the time you reach State Pension age, your contributions picture is basically baked in. What changes is just the future deductions on your wages. Your employer still pays their NI, because that supports the system. You, as an employee, don’t. That’s the law’s intent — no double paying once you’ve crossed the finish line for eligibility. It’s simple, yet the real world throws paperwork at it until it looks complicated.
And yes, there are edge cases. If your first State Pension payment arrived late, DWP may owe arrears for those weeks after you reached pension age. If you’re a carer, or you claimed certain benefits, NI credits might fill gaps that weren’t obvious, which changes the sums behind the scenes. These are separate from NIC refunds, yet they often surface together when people start digging. *You might be due money.* **Not everyone will get £500, but a decent chunk will get something — and it’s theirs.**
Practical moves that quietly pay off
Open your banking app and set a 10‑minute timer. Pull the last six payslips and jot down the “Employee NIC” line from the month before and after your 66th birthday. If you see anything above £0.00 after that birthday period, total it. Email payroll with a short note and your dates. If they can’t fix in-year, head to GOV.UK and search “National Insurance refund”. Keep it all in one thread. If you’re self-employed, log in to your tax account and check the period Class 2/4 was charged for compared with your date of birth. Keep screenshots.
Common pain points: dates don’t match, employers say they “can’t find” your DOB, or someone tells you to wait until next April. Push back politely. The birthday rule is your anchor. If you worked multiple jobs, treat each separately. If you left a job soon after turning 66, you can still ask that old employer to correct the records or go straight to HMRC. Stay specific and kind — the person reading your email is juggling 200 other queries. And if life is heavy right now, ask a trusted friend to sit with you while you do it. Two pairs of eyes help.
“Once you reach State Pension age, employee NIC should stop. If it didn’t, claim. It’s not a windfall — it’s a correction,” says pension specialist Jo Palmer.
Quick checklist to keep your claim moving:
- Confirm your date of birth in payroll/HR records
- Note the exact pay period containing your 66th birthday
- List all employers since that date
- Attach copies of payslips showing deductions after your birthday
- Keep a log of calls, names, and dates in one place
Where this leaves us
The age gap here isn’t about generations. It’s the space between the day you turn 66 and the day a payroll system wakes up. Quiet, boring, costly. People scrolling past their payslips miss it. Then a neighbour mentions a refund and the penny drops. Share this with the friend who still works a shift at the surgery, or the brother who drives weekends. A few screenshots now could mean an extra £500 this year. Or £120. Or £900 across two jobs. The figure matters less than the feeling: a small, rightful nudge in your favour.
Money stories travel best in whispers. One person checks, then another. The more we get comfortable asking why a line is on a page, the less these drips turn into puddles. If you’ve been through it — if you chased a refund, or hit a wall and found a way round — tell someone. The fix is straightforward, the impact personal. And in a year where everything feels like it costs more, a correction like this lands with a thud of relief.

FAQ :
- Who can get this refund?Anyone who worked past State Pension age and had employee National Insurance deducted after their 66th birthday. It applies to single or multiple jobs, and to some self-employed cases via Class 2/4.
- How much could I be owed?It varies with earnings and weeks affected. Many refunds sit between £200 and £600. A higher wage or longer delay can tip it above £500.
- Does stopping NI reduce my State Pension?No. Once you reach State Pension age, your future employee NICs stop but your pension entitlement is already set by your contribution record up to that point.
- What if I’m self‑employed?Class 2 and Class 4 NI are not due for periods after you reach State Pension age. If they were charged for those weeks, correct your return or claim a refund through HMRC.
- Can I backdate a claim?Yes, within HMRC time limits. If the overpayment was in the current year, payroll can usually fix it. For earlier years, you’ll claim via HMRC — keep payslips and dates handy.
