What happens if the tax figure on a P45 is wrong?

When someone changes job, a P45 is created by the old employer and passed, by the employee, to the new employer. In some cases, the P45 includes figures for pay and tax, which are used by the new employer. The new employer should check the figures from the P45 and ensure the correct tax figure is used.

If you add the information from the P45 using the 'Add Employee' option, our system will automatically check the tax figure and correct it, if necessary.
