Reaching State Pension age is a major milestone, but many self-employed workers and directors are unknowingly overpaying the taxman. Here is how to legally stop your National Insurance contributions and keep more of your hard-earned money
Once you reach the State Pension age in the UK (currently 66 for both men and women), you are no longer required to pay National Insurance (NI) on your earnings. For the self-employed and small business owners, this transition isn’t always automatic, meaning you must be proactive to protect your income.
According to official UK Government guidance, you stop paying Class 4 National Insurance from the start of the tax year after you reach State Pension age.
Does this include Limited Company Directors?
Yes. If you are a director of your own limited company, you are technically an employee. You stop paying Class 1 NI as soon as you reach State Pension age.
However, your company must still pay employer National Insurance contributions on your salary if it exceeds the secondary threshold. To stop your personal deductions, you must provide your company’s payroll (or your accountant) with proof of age, such as a birth certificate or passport.
What about dividends?
It is important to note that National Insurance is never charged on dividends, regardless of your age. Dividends are taxed through Dividend Tax, not NI. If you pay yourself primarily through dividends, you won’t see a change there, but you will see an immediate boost on any portion of your income taken as a salary.
How much will you save when you stop National Insurance?
Stopping NI contributions is essentially an instant pay rise. Based on 2026/27 rates, here is what stays in your pocket instead of going to HMRC:
For Sole Traders (Class 4 NI)
6% saving on profits between £12,570 and £50,270.
2% saving on profits above £50,270.
| Annual Profit | Estimated Annual NI Saving |
| £30,000 | ~£1,045 |
| £50,000 | ~£2,245 |
| £70,000 | ~£2,655 |
For Directors on a Salary (Class 1 NI)
Directors pay a higher rate of employee NI (currently 8%). If you take a salary of £30,000, you would save roughly £1,390 per year in personal deductions once you reach the qualifying age.
How to stop your National Insurance payments
The process depends on how you work:
Self-Employed (Sole Traders)
You pay Class 4 NI through Self Assessment. Your tax return software should automatically calculate the exemption based on your date of birth, but you must ensure your records are up to date with HMRC.
Self-employed National Insurance rates – GOV.UK
Limited Company Directors
You must show your accountant or your company’s payroll department proof of age. They will then use the correct NI category letter (usually ‘C’) to ensure no further deductions are made from your paycheque.
Why you might be able to request a refund
If you continue working past the retirement age and don’t flag your age, HMRC may continue to take contributions. While you can claim a refund, it is far better for your cash flow to stop the payments immediately.
With the cost of living remaining high, removing this tax burden provides extra support for those choosing to work past the government’s retirement age.
