Getting the timing right
The first submission
Register as an employer with HMRC as soon as you know your first payday, ideally a few weeks in advance, then run payroll from day one using a starter checklist, submitting a Full Payment Submission on or before every payday.
HMRC registration cannot usually be backdated more than a limited period and takes several working days to process, so it needs to happen before the company incorporates its first payroll run rather than after. Most new directors set the first payday for the end of the month following incorporation, giving time for references to arrive.
Once registered you receive a PAYE reference and an Accounts Office reference, both needed to file returns and pay HMRC. Choose RTI compatible software from the start rather than trying to bolt it on retrospectively once a few months have already passed.
Because a new director usually has no P45 from a previous employer relevant to the new company, a starter checklist sets the tax code, normally 1257L on a cumulative basis from the first payday of the tax year. The first FPS reports this starter information alongside pay, tax and NIC.
If the first payday falls partway through the tax year, cumulative tax bands still apply as if the director had been paid since April, which often produces no tax due on a modest opening salary until several months in.
