P60 NICs and Self-Assessment

I think this is of little or no consequence for my SATR. I am NOT self-employed. My employer moved my employment to another company under its ownership during a tax year. This is reflected correctly for Pay and Tax Deducted on my P60 because both employments are listed. The NICs section on the P60 only shows contributions during my current employment, so it's unlikely the NICs from the previous employment have been lost. It's just that they are not shown on the P60. How can I check this with HMRC? I'd also like to check the NICs missing from my P60 for the previous employment in the same tax year do not have any consequence for the SATR already filed. As far as I can tell, the SATR does not make any allowance for NICs paid or due (when NOT self-employed). Is this correct?

Hi,
 

The P60 would only show NI contributions from the 'current employment' they can carry forward the pay and tax figures from the 'old employment' on the P60. If you have signed up for the Personal Tax Account, you can view the NI details submitted to HMRC under the PAYE section and checking a previous year. The SA return would not calculate NI if you were not declaring income from Self-Employment . Thank you.
