A single missed deadline can be enough to trigger a payroll penalty from HMRC, even when the underlying error was accidental. Late submissions, late payments, and inaccurate reporting are all treated as compliance failures, and the financial consequences build up quickly if they are not addressed.
For employers running multiple PAYE schemes or managing a complex payroll, this risk is worth taking seriously. This guide sets out exactly when payroll penalties apply, how much they can cost, and what practical changes reduce the chances of receiving one in 2026/27.
Why payroll penalties catch employers out
Most payroll penalties are not the result of deliberate non-compliance. They tend to come from small, avoidable gaps in process: a submission sent a few hours late, a payment that clears one day past the deadline, or a figure that was entered incorrectly and never corrected. Because HMRC applies penalties automatically in many cases, there is often little room for a “genuine mistake” defence once the deadline has passed.
This matters more in 2026/27 than in previous years, since several rate and process changes took effect from 6 April 2026. A lot of employers do not realise that Real Time Information (RTI) requirements mean payroll data must reach HMRC in real time, on or before payday, rather than at the end of the month. Any gap between your pay run and your submission process is where payroll penalties tend to originate.
What triggers an HMRC payroll penalty?
Payroll penalties generally fall into three categories:
- Late Full Payment Submission (FPS) where payroll data is not sent to HMRC on or before payday
- Late PAYE payment where the tax and National Insurance (NI) owed does not clear into HMRC’s account by the deadline
- Inaccurate submissions where the data submitted is wrong, whether through an honest error or a deliberate omission
Each of these is assessed and charged differently, so it helps to understand them individually rather than treating “payroll compliance” as a single, undifferentiated risk.
A breakdown of payroll penalty types
Late FPS submission penalties
Your FPS must reach HMRC on or before the date employees are paid. Submitting it later the same day can still count as a late submission, which surprises a lot of employers who assume same-day filing is acceptable.
HMRC does apply two practical concessions, though neither should be relied on as a guarantee:
- The first late submission in a tax year is not usually penalised
- Submissions received within three days of payday are often treated leniently
Beyond these easements, persistent late filing results in a monthly penalty based on the size of your PAYE scheme:
| Employees in PAYE scheme | Monthly penalty | Annual exposure |
|---|---|---|
| 1–9 | £100 | £1,200 |
| 10–49 | £200 | £2,400 |
| 50–249 | £300 | £3,600 |
| 250+ | £400 | £4,800 |
Where a submission is more than three months late, HMRC can add a further charge equal to 5% of the PAYE and NI owed. For organisations running more than one PAYE scheme, each scheme is assessed separately, which means penalties can accumulate faster than expected across a group structure.
Late PAYE payment penalties
Filing on time is only half the requirement; the PAYE liability itself must also clear into HMRC’s account by the deadline. Electronic payments must normally clear by the 22nd of the month following the end of the tax month. Where the 22nd falls on a weekend or bank holiday, payment needs to clear on the preceding working day.
Penalties for late PAYE payment scale with how often payments are late across the tax year:
| Number of late payments in the tax year | Penalty rate |
|---|---|
| 1–3 | 1% |
| 4–6 | 2% |
| 7–9 | 3% |
| 10–12 | 4% |
Additional surcharges apply on top of these rates: a further 5% after six months unpaid, another 5% after twelve months, and daily interest calculated from the original due date. This works well as a warning system for HMRC, but for employers it means a single missed payment early in the tax year can compound significantly by year end if the pattern repeats.
Penalties for inaccurate submissions
Inaccuracy penalties are treated differently depending on whether HMRC judges the error to be careless or deliberate:
| Type of error | Penalty range |
|---|---|
| Careless, corrected without prompting | 0–30% |
| Careless, corrected only after HMRC prompts | 15–30% |
| Deliberate but not concealed | 20–70% |
| Deliberate and concealed | 30–100% |
The pattern here is consistent: employers who identify and correct their own errors are treated more favourably than those where HMRC finds the issue first. Good record-keeping matters here too—if you need to challenge a penalty notice, you can appeal through your HMRC online account, but you will need clear evidence to support the appeal.
A practical scenario
Consider a mid-sized employer running payroll for 80 staff across two PAYE schemes. A change in personnel means the FPS is submitted two days late in June, then again in September. Under HMRC’s concessions, the June submission may be overlooked as the first late filing of the year. The September submission, however, falls outside that easement and triggers a £300 monthly penalty under the 50–249 employee band, applied separately to each scheme if both are affected. Two missed deadlines, in other words, can result in penalties that few payroll teams would expect from what looked like a minor administrative slip.
Practical steps to reduce payroll penalty risk
The organisations that avoid payroll penalties consistently tend to build a small number of habits into their routine, rather than relying on individual vigilance:
- Set deadline reminders independently of your payroll software. Even reliable systems benefit from a second, manual checkpoint around FPS and PAYE due dates.
- Automate RTI submissions wherever your software allows it. This removes the point of human error that causes many late filings.
- Align BACS payment runs with PAYE deadlines, so cash leaves your account with enough lead time to clear by the 22nd.
- Audit payroll data on a regular cycle, not only at year end, so inaccuracies are caught and corrected before HMRC does.
- Correct errors as soon as they are found. Voluntary correction is treated far more favourably than a penalty triggered by an HMRC review.
- Make sure your payroll team has a clear view of the full UK tax calendar, including how bank holidays shift payment deadlines.
Our guide to FPS and EPS submissions covers the mechanics of RTI reporting in more depth, and pairs well with our broader UK payroll compliance guide if you want the full picture of an employer’s obligations for 2026/27. For the government’s own reference on penalty rates and appeals, gov.uk’s PAYE penalties guidance sets out the official position, and Cintra’s Real Time Information knowledge base article is a useful additional resource on RTI requirements for 2026/27.
Reducing payroll penalty risk for good
Payroll penalties rarely come from a single dramatic failure. In practice, they build from small gaps — a late submission here, a missed payment date there — that accumulate across a tax year. The organisations that manage this well are the ones that stop relying on memory and build the deadlines directly into their processes, whether through software automation, clear internal checklists, or simply a second person checking the calendar.
If your current setup still depends on manual reminders or last-minute checks, it is worth reviewing before the next filing deadline arrives. Speak to our specialists about how our fully managed payroll services keep RTI submissions and PAYE payments on schedule, or explore our payroll software if you would prefer to manage the process in-house with stronger automation in place.
