The CIS300 monthly return: a complete guide for contractors
The CIS300 is due by the 19th of every month — even in months when you paid no subcontractors. Here is exactly what goes on the return, every deadline, and how the penalty ladder works.
What is an FPS? The Full Payment Submission explained
The FPS is the report you send to HMRC every time you pay your employees — due on or before payday, not at the end of the month. Here is exactly what goes in it, how the deadline works, and how to fix an FPS that went wrong.
The Employer Payment Summary (EPS): when to send one — and when you don’t need to
Unlike the FPS, the EPS is not sent every payday — many employers never need one in a normal month. Here are the six situations that require an EPS, the deadline that makes it count, and a simple monthly decision check.
CIS deduction rates for 2026/27: 20%, 30% and gross payment status explained

How to register as an employer with HMRC for PAYE
You must register with HMRC before your first payday — but you cannot register more than two months early, and the reference can take up to 30 working days to arrive. Here is how the timing works and exactly what to do.
What is RTI? Real Time Information reporting explained
Since 2013, every UK employer has reported pay to HMRC in real time — an FPS on or before each payday, and an EPS when there are adjustments to make. Here is how the whole system fits together, and what each submission is for.
Late FPS submission: what HMRC charges and how to put it right
Missed the on-or-before-payday deadline for an FPS? The penalty is monthly and scales with your headcount — but your first late submission of the tax year is free, and filings within three days are normally let through. Here is exactly how the rules work and how to fix a missed submission.
