Herein, do employers need p45?
By law your employer must give you a P45 - ask them for one. You can check how much tax you paid last year if you think you might have paid too much.
Secondly, does p45 show previous employer? In relation to your P60 though in Jan 2008, your new employer will need your P45 to key in your earnings to date in your previous employment and your p60 will show your earnings in THIS employment and previous employment seperatly.
Similarly, you may ask, can you get a job without p45?
If you don't have a P45 to give to a new employer, the new employer should ask you to complete a starter checklist. If they don't, print one off, complete it and give it to your new employer anyway. The phrase P46 is still sometimes used to refer to the starter checklist.
Do you still need to send p45 to HMRC?
Employers who are filing RTI should no longer send forms P45 (Part 3) or P46 to HMRC; starter details will be included on their FPS instead. The form is for employer use only and must not be sent to HMRC. The information an employer needs to gather to work out a new employee's tax code is available on GOV.UK.
