I ran a payroll last year where the wrong tax code was applied to an employee's pay during the year. Client has moved to another accountant so I cannot access my tax code notices via Brightpay payroll. Client now thinks I was in the wrong, but I believe it was HMRC's fault.
Brightpay helpline staff don't know the answer to this - it's difficult to get hold of the really knowledgeable ones these days. Am I right in thinking there is no way I can find data via my payroll software to "prove" how a tax code change was made?
