Self-employed? you might overpay

Frequently Asked Questions

How do I know if I have missing NI years?

You can check your NI record on HMRC online or via State Pension forecast. Our free review identifies gaps and tells you exactly what to do.

Can I pay voluntary contributions for past years?

Yes, usually for the last 6 tax years. After that, the window closes. We calculate cost vs benefit so you only pay if it increases your State Pension.

Do self-employed pay Class 2 NIC in 2026/27?

No — Class 2 has been abolished for profits above £12,570. You still get NI credits toward State Pension via Class 4 contributions.

How much does a full NI review cost?

Our fixed fee starts at £195 for a complete NI record check, pension impact report, and advice on filling gaps. Complex cases quoted upfront.

Will you deal with HMRC on my behalf?

Absolutely. We handle HMRC forms, corrections, and voluntary contribution payments. You just get the outcome.
