A monthly payroll run is a fixed sequence tied to two HMRC deadlines: the Full Payment Submission on or before each pay date, and the PAYE payment by the 22nd of the following month if you pay electronically (the 19th if you pay by post). Miss the first and you risk a late-filing penalty. Miss the second and HMRC charges interest and can add late-payment penalties.
Each cycle we collect your variable inputs (hours, overtime, bonuses, starters and leavers), calculate gross to net, run the auto-enrolment pension assessment, and file the FPS to HMRC before payday. We then tell you the single figure to pay HMRC and the date it is due, so there are no surprises mid-month.
A worked example. Take one employee on an annual salary of £30,000, paid monthly. That is £2,500 gross a month. Income tax is charged once pay passes the £12,570 personal allowance, and employee National Insurance once weekly pay passes the £242 primary threshold. On the employer side, secondary Class 1 NIC is 15% on earnings above the secondary threshold of £96 a week (around £5,000 a year). Before the Employment Allowance, that employer NIC is roughly £3,750 across the year on this salary. If you are eligible for the Employment Allowance, the first £10,500 of that secondary NIC bill is wiped out, so a small employer with one or two staff often pays no employer NIC at all.
If you run payroll less often, there is relief on the payment side too. Employers who usually owe HMRC less than £1,500 a month can ask to pay PAYE quarterly rather than monthly, which eases cash flow. We confirm whether you qualify and arrange it.
