Have You Paid Enough Into Your National Insurance?

Many small business owners and self-employed individuals, including those using accountants for sole traders, assume their National Insurance contributions are automatically up to date. If your profits have changed, you’ve had gaps in work, or your business structure has changed, our Self Assessment tax return support can help you understand how your tax position and NI record fit together.

At Yorkshire Accountancy, we often get asked whether a client’s NI record is complete—and the truth is, the answer lies with HMRC.

Why National Insurance Matters

NI contributions count towards:

Your State Pension (you usually need 35 qualifying years to get the full amount)
Maternity Allowance
Employment and Support Allowance
Access to other state benefits

Having a full and accurate record is essential for your future financial security.

Important Deadline: 5 April 2025

Here’s what Martin Lewis and others have been highlighting recently: you only have until 5 April 2025 to fill in any gaps in your National Insurance record going back to 2006. After that, you’ll only be able to go back 6 years.

If you have missing years between 2006 and 2017, this is a rare opportunity to top them up and potentially increase your State Pension by thousands over your retirement.

Why this matters:

Each full qualifying year adds to your State Pension entitlement.
It costs around £900 to top up a year.
That can boost your annual pension by around £300+.
Meaning you’d earn back the cost in just a few years of retirement.

We strongly recommend checking your NI record now, so there’s still time to act before the deadline.

How to Check Your NI Contributions

The fastest and easiest way to check is via the HMRC app or your Personal Tax Account. As your accountant, we don’t have access to this information online—we can only request it via a manual paper form, which takes several weeks.

Option 1: Use the HMRC App

Download the HMRC app from the Apple App Store or Google Play.
Sign in using your Government Gateway ID and password. If you don’t have one, you can create it during the sign-up process.
Go to “National Insurance” from the main menu.
Click on “View your National Insurance record”.
You’ll see a breakdown of each tax year, whether it counts as a qualifying year, and any gaps.

Option 2: Use the Personal Tax Account Online

Visit: www.gov.uk/personal-tax-account
Sign in or register with your Government Gateway credentials.
Click on “Check your National Insurance record”.
You can view all past tax years, including:
- Qualifying years
- Years with gaps
- How much it would cost to top up missing years

These tools are completely free and give you instant access to the information.

Can an Accountant Check If You Have Paid Enough National Insurance?

This is one of the most common questions we get. The short answer is: not instantly.

As accountants, we don’t have automatic access to your National Insurance records, even if we are authorised as your agent for tax matters.

To check your NI contributions on your behalf, we would need to:

Complete a manual request form to HMRC
Ask you to sign it and return it to us
Post it to HMRC and wait several weeks for a reply

This can be a slow process, which is why we recommend using the HMRC app or Personal Tax Account if you want a quick answer.

That said, if you do prefer for us to handle it, we’re more than happy to submit a request—just get in touch and we’ll guide you through it.

When Gaps Happen

You may have missed a year of NI if:

Your profits were below the Small Profits Threshold (currently £6,725 in 2024/25)
You didn’t pay Class 2 NI voluntarily
You took a break from self-employment
You were a director taking dividends only, not salary
You had a period of bankruptcy or change in UTR

Can You Make Up for Missed Years?

Yes—in most cases, you can pay voluntary Class 3 contributions to fill gaps.

You can usually go back up to 6 years
Until 5 April 2025, you can go back as far as 2006
Each year costs around £17.45 per week (£906.40 for a full year in 2024/25)
Some older years might no longer be eligible for top-up after the deadline

Filling in gaps now could be far cheaper than missing out on thousands in State Pension later.

What If You’re Not Sure?

If you can’t access your Personal Tax Account or you’re unsure whether topping up is worthwhile, our team can provide personal tax advice and help you understand your options.

Yorkshire Accountancy can help by:

Submitting a manual request to HMRC for a breakdown of your record
Advising on whether it’s worth making voluntary contributions
Helping you understand the implications for your State Pension

Just bear in mind that HMRC can take several weeks to reply to manual requests.

Final Thoughts

It’s easy to overlook your NI record when you’re focused on running your business. But just a few missing years could reduce your future pension.

Take five minutes to check your record today—especially before 5 April 2025.
