An error at the Department for Work & Pensions (DWP) means that married women who paid a lower rate of National Insurance (NI) contributions before 1977 (known as the “small stamp”) may be due a top-up to their State Pension. The DWP says it first became aware of the issue last year. Where underpayments are identified, the DWP will contact the person to inform them of the changes to their State Pension amount and of any arrears payment they will receive but you may still want to check with them if you think you’re affected.
LCP, the company that first brought this issue to the DWP’s attention, has created a free online calculator that you can use to see if this might apply to you. You can find it here: https://www.lcp.uk.com/is-your-state-pension-being-underpaid/.
