NI Number | if not known, how to find it
When taking on a new employee you will need to know their National Insurance (NI) number (amongst other things).
There are 4 possible ways to obtain this, if your employee doesn’t know it.
In order of speed:
- Use the HMRC App or their personal tax account (PTA).
- Find their NI number on previous payslips, P60s, or letters about tax, pensions and benefits.
- Complete a form and get HMRC to post their NI number to their home address, which can take up to 15 days.
- Contact the National Insurance Number Helpline and HMRC will post confirmation to them.
