Stop Guessing Payroll Dates: Your Month-by-Month Plan
Payroll deadlines can creep up fast. RTI submissions, pension uploads, starters, leavers, P60s, P11Ds, it can all blur into one long list of jobs. For small employers, missing just one date can mean penalties, annoyed staff, or a late night trying to fix something that should have been simple.
A clear month-by-month payroll calendar turns guesswork into a steady routine. Instead of thinking, "I hope we did that," you know exactly what has to happen and when. Pay days stay on track, HMRC is kept happy, and staff get clear answers when they have questions about tax, pensions or payslips.
At NFH Accountancy in Horsham, we keep things personal and easy to contact. Whether you have one member of staff or fifty, pay weekly or monthly, on the 25th or the last working day, the pattern can be shaped around you. Let us walk through a real-life payroll year from April to March so you can see, through one business owner's experience, how a simple structure keeps everything under control.
Meet Sarah: From Scrambling to Structured Payroll
Sarah runs a small design studio in Horsham with six employees, a mix of full-time staff and part-timers. For years she relied on memory, a few notes in her diary and her inbox to keep payroll on track.
One April, she realised she had:
- Missed the deadline for sending an FPS on payday
- Forgotten to upload pension data for two consecutive months
- Delayed issuing a P45 for a leaver, who was chasing her for weeks
None of these were disastrous on their own, but together they left Sarah feeling out of control and anxious around payday. That's when she asked NFH Accountancy to help her build a simple, tailored payroll calendar.
April to June: Setting up the New Payroll Year Properly
When the new tax year started, we sat down with Sarah to set things up properly instead of carrying old problems forward.
Key April jobs for her business included:
- Rolling the payroll into the new tax year
- Updating tax codes and new thresholds in her payroll software
- Checking starter information for her newest employee was complete and correct
- Confirming her PAYE payment method and payment dates with HMRC
- Reviewing workplace pension settings, contribution rates and re-enrolment dates
From here, we wanted a regular rhythm. For every pay run, RTI rules mean a Full Payment Submission (FPS) must be sent to HMRC on or before payday. Because Sarah sometimes needed to claim statutory payments and occasionally had months with no pay for a casual worker, we agreed when an Employer Payment Summary (EPS) would be prepared.
We helped her mark in a shared calendar:
- All pay dates for the year
- The cut-off for timesheets and changes
- PAYE and NIC payment due dates, allowing for bank cut-off times
Starters and leavers had often knocked her rhythm off because there was no checklist. Together we built a simple list that matched her studio:
- P45s for new staff where possible
- Right-to-work checks
- Pension enrolment status
- Contact details and emergency contacts
For leavers, the checklist covered final pay, holiday pay, pension status and leaving details so everything was recorded quickly and cleanly. Within the first quarter of the year, Sarah already felt fewer things were "living in her head".
July to September: Smooth Summer Payrolls and Pension Uploads
Summer had always put more strain on Sarah's payroll. Staff took holidays, she brought in a student for a few weeks, and hours bounced up and down.
We agreed clear cut-off dates. Because she paid monthly, we decided when timesheets must be in so that:
- Holiday pay was worked out fairly
- Variable hours were recorded properly
- There was time for her to approve pay before it was run
Once payroll was processed, pensions came next. For each pay run, we:
- Uploaded payroll data to her pension provider
- Checked that staff contributions and employer contributions looked right
- Dealt with any rejected or flagged records promptly
Previously, missed or late pension uploads had created stress for her team, who liked to see their pension growing regularly. With cloud-based systems, we set automatic reminders and used a shared checklist so pension work followed straight after each RTI submission, almost like a paired task.
In July, we also booked a short review call. Sarah used this time to:
- Check her directors' pay and dividend strategy still suited her plans
- Review any benefits that might later end up on P11Ds
- Talk through a planned hire for autumn
We kept these conversations informal and easy. For Sarah, a ten-minute call early in the year prevented a bigger tangle close to year-end.
October to December: Planning Ahead for Year-End and Festive Pay
By October, we encouraged Sarah to lift her head up and look ahead. HMRC guidance for the coming tax year was starting to appear, including changes to student loans and early news on minimum wage increases.
October became her tidy-up month:
- Employee addresses and contact details were checked
- Missing or questionable National Insurance numbers were reviewed
- Student loan flags and deductions were updated
Then there was the festive period. Sarah liked to pay a little earlier in December and usually rewarded the team with a small bonus.
Previously, she had:
- Paid staff early without updating the payment date in her FPS
- Delayed pension uploads until January
- Struggled to process a leaver who finished in mid-December
Together, we agreed a simple pattern for that year:
- December pay would be brought forward by a few days
- The FPS would always use the actual payment date, not the usual date
- Pension uploads would move forward in step with the earlier payday
- Any leavers would be processed within two working days of notice
Think of her like any busy Horsham retailer juggling extra weekend staff, lots of overtime and an early December pay date. With the calendar in place, we simply slid everything earlier:
- Timesheet cut-off brought forward
- Payroll processed on the new agreed day
- RTI filed on or before the real payment date
- Pension file uploaded as soon as payroll was final
The result was that staff were paid when they expected, HMRC records matched the bank payments, and pension contributions landed on time. For the first December in years, Sarah didn't spend Christmas Eve checking payroll emails.
January to March: P60s, P11Ds and Year-End Clean-up
After the festive rush, January and February became quiet housekeeping months.
This is when we like to quietly check for clients like Sarah:
- All leavers for the year are processed correctly
- Tax and National Insurance totals line up across the year
- PAYE and pension contributions match accounting records
- Any oddities, like large bonuses or backdated pay, have been handled properly
Cloud-based reports made these checks far quicker. We pulled year-to-date figures, compared them to what had hit the bank and her accounts software, and spotted any gaps while there was still time to fix them.
March became her big tidy-up. Final RTI submissions for the tax year needed to be accurate. It was also the time to:
- Identify benefits in kind that might need to be reported on P11Ds later
- Prepare P60 reports ready to issue to staff by the deadline
- Line up payroll figures with her year-end accounts so tax planning was smoother
Because this was managed calmly in the background, year-end stopped being a mad rush. A personal payroll service kept the timetable, sent gentle nudges for missing information, and explained things like P60s and P11Ds in plain language. Her staff got clear answers, and Sarah felt in control rather than chasing paperwork.
How a Tailored Payroll Calendar Brought Sarah Peace of Mind
By the end of her first full payroll year on the new system, Sarah noticed:
- Fewer letters and chasers from HMRC
- Fewer staff queries about missing pay or pensions
- Cleaner figures for her accounts, with less time spent unpicking errors
Instead of firefighting, she worked to a pattern that suited her pay dates and her team.
At NFH Accountancy, we take payroll services in Horsham and across the UK and make them feel calm and human, just as Sarah experienced. We build a calendar around your pay cycle, working patterns and software, then look after the RTI submissions, pension uploads, starters, leavers and year-end forms in a way that is personal, adjustable and easy to discuss.
