Employer Insolvent - Unpaid PAYE

My employer became insolvent, and had a large PAYE debt. My salary was always taxed correctly, but the PAYE has not been paid over to HMRC, and I am worried this will affect my PAYE and National Insurance Contributions. Will there be a gap in my records? Do I have to pay voluntary contributions to fill the gaps (even though my employer had already deducted it from my pay)?

Hi,
If the customer is concerned they can check their PTA and if there is a gap then:
•    from October following the end of the tax year they can write to
Individual Caseworker
PT Operations North East England
HM Revenue & Customs
BX9 1AN
•    they should include
o    all employer details which should include employers name and address, the customers staff/payroll number (if known) and the tax year the earnings are missing from.
o    evidence of their earnings during the period for example pay slips, P45 or P60 certificates
o    their personal details specifically their full name (with previous name if known), date of birth, address, a contact number and their NINo
o    their signature.
Thank you.
