Why am I being charged Class 2 National Insurance in my 2024/25 Self-Assessment?

Some self-employed taxpayers are mistakenly charged Class 2 NICs due to an HMRC IT issue. If your profits exceed £12,570, you should only pay Class 4 National Insurance, not Class 2. Always check your self-assessment 2024/25 calculation to ensure it is correct.

Do I need to pay Class 2 NICs through Self-Assessment for 2024/25?

No. From 6 April 2024, Class 2 NICs are voluntary for self-employed individuals with profits below £6,725. Voluntary contributions can help build qualifying years for your State Pension, but if your profits are above this threshold, Class 2 should not appear on your self-assessment.

What should I do if my Self-Assessment shows the wrong Class 2 NIC charge?

If you’ve filed your 2024/25 self-assessment and notice an incorrect Class 2 NIC charge, contact HMRC to request a correction. If you haven’t filed yet, consider waiting until HMRC resolves the issue (expected by September 2025).

What happens if I already paid the incorrect Class 2 NICs through Self-Assessment?

HMRC will refund or credit any incorrect Class 2 NIC payments to your self-assessment account once the error is fixed. Keep proof of payment and HMRC correspondence for reference.

When is the deadline for submitting my 2024/25 Self-Assessment?

The online filing and payment deadline for 2024/25 self-assessment is 31 January 2026. The HMRC Class 2 NIC error does not affect this deadline. Submit on time to avoid late filing penalties.

Sole Trader or Limited Company? 2025/26 UK Guide

Sole Trader or Limited Company: Which is Right for Your Business?

Deciding between operating as a sole trader or limited company is one of the most important early choices for small business owners and the self-employed.

Your business structure affects how much tax you pay, how much paperwork you must complete, your legal liability, and how clients view you.

With tax and reporting rules updated for the 2025/26 UK tax year, it’s vital to understand the differences before you start or change your business structure.

What Does “Sole Trader or Limited Company” Mean?

If you operate as a sole trader, you and your business are legally the same person.

All profits are personal income and are taxed through your Self Assessment return, including Income Tax and National Insurance Contributions (NICs).

A limited company is a separate legal entity.

It pays Corporation Tax on profits (between 19% and 25% depending on profit levels), and you can draw income as a combination of salary and dividends — potentially offering tax efficiency at higher profit levels.

Tax Responsibilities: Sole Trader or Limited Company

When considering sole trader or limited company status, taxation is often front of mind:

Sole traders pay Income Tax on profits above the personal allowance and Class 2/4 NICs.
Limited companies pay Corporation Tax on profits, and directors pay tax and NICs on salaries but can take dividends taxed at different rates.

For many smaller businesses under around £40,000–£50,000 profit, a sole trader can be simpler and cost-effective. If profits grow, incorporation may offer tax advantages.

Liability & Legal Protection for Sole Traders vs Limited Companies

A key structural difference in the sole trader or limited company decision is liability:

As a sole trader, you are personally liable for all business debts and legal claims.
A limited company offers limited liability, separating your personal assets from those of the business.

This legal protection can become critical as your business grows or takes on larger contracts.

Administration, Reporting & Compliance

Beyond tax and liability, consider the regulatory side of sole trader or limited company structures:

Sole traders submit an annual Self Assessment and keep basic records.
Limited companies must file annual accounts, a Corporation Tax return, and statutory information with Companies House — which increases compliance and reporting.

New HMRC rules such as Making Tax Digital for Income Tax are rolling out in 2025/26 and may affect both structures, particularly with quarterly reporting for VAT-registered businesses.

How to Decide: Sole Trader or Limited Company?

There is no one-size-fits-all answer to sole trader or limited company — it depends on:

Expected profits and tax efficiency goals
Appetite for administrative and compliance duties
Desired legal protection and business growth plan
Whether you intend to take on employees or external finance

Speaking to an accountant can make the decision clearer.
