Payroll Services for Harrow small businesses — matched to a specialist.
If someone on your Harrow payroll — including you as a director — gets paid, HMRC expects an RTI submission inside 24 hours. Miss one, and the penalty is automatic.
PAYE, RTI submissions, auto-enrolment pensions, statutory pay (sick, maternity, paternity), and director-only payrolls — handled by the specialist we match you with on a weekly, fortnightly, four-weekly, or monthly cycle. Every Harrow employer with even a single director-employee on the books has to operate PAYE and submit Real Time Information to HMRC inside 24 hours of payment; the engagement covers the full statutory workload plus pension auto-enrolment compliance.
How the work actually breaks down.
Every Harrow employer running PAYE has to submit a Full Payment Submission (FPS) to HMRC on or before the date employees are paid — not at the end of the month, not at week-end, but inside 24 hours of the payment hitting the employee's bank. This is the headline rule of Real Time Information. The FPS reports each employee's pay, tax deducted, NIC, student loan repayments, and pension contributions for that pay run. Miss the FPS deadline and HMRC issues an automatic late-filing penalty starting at £100 for the first month and escalating per missed period. The penalty regime is automated; appeals only succeed for genuine reasonable excuse. The payroll specialist we match you with takes on the FPS deadline as part of the engagement.
Alongside the FPS, an Employer Payment Summary (EPS) goes to HMRC by the 19th of the following month — this is where you reclaim Statutory Maternity / Paternity / Adoption Pay (small employers reclaim 103%, larger employers reclaim 92%), report any CIS deductions you've suffered as a subcontractor (limited companies offset these against the PAYE bill), and notify HMRC of months with no paid employees. The EPS is also where you claim the Employment Allowance — up to £5,000 a year off the employer's NIC bill, available to most Harrow small businesses except single-director companies and businesses where one director earns more than the secondary NIC threshold. The accountant verifies eligibility annually because the rules tightened in 2020.
Auto-enrolment pension is now a default, not an option. Every UK employer with at least one employee earning over £10,000 a year aged 22 to State Pension Age has to enrol them in a qualifying workplace pension, contribute at least 3% of qualifying earnings, and re-enrol every three years anyone who'd previously opted out. The Pensions Regulator audits compliance via the Declaration of Compliance (within five months of the duties start date) and the triennial re-declaration. Most Harrow small businesses use The People's Pension, Smart Pension, NEST, or Aviva Workplace as the qualifying scheme; the payroll software calculates contributions automatically once the scheme is connected. Setup is one-off; ongoing contributions are part of every payroll run.
Director-only annual payrolls are the simplest engagement type and a common Harrow request. A single-director limited company often pays the director a salary at the secondary NIC threshold (£12,570 in 2024-25, rising to £12,570 still in 2025-26) — high enough to count as a qualifying year for State Pension and use the personal allowance, low enough to avoid employer's or employee's NIC. The payroll runs once a year, with a single FPS reporting the full year's salary plus zero-pay months as 'no payment due' EPS submissions in between. Total annual fee for this kind of scheme is typically in the £150-300 range — far cheaper than running a monthly cycle and equally compliant.
Year-end is where loose ends are tied. Every employee gets a P60 by 31 May summarising the prior year's pay and deductions. Any benefit-in-kind provided to an employee or director — company cars, private medical insurance, beneficial loans over £10,000, gym memberships — has to be reported on a P11D by 6 July, with the corresponding Class 1A NIC paid by 22 July. The final EPS for the year goes to HMRC by 19 April and includes the employer's annual confirmation that all statutory submissions are complete. The payroll specialist handles this whole cycle without owner involvement beyond data confirmation.
Where the standard playbook doesn't apply.
Statutory Maternity Pay (SMP) is one of the most procedurally complex items most Harrow small businesses encounter. An eligible employee gets up to 39 weeks of SMP (six weeks at 90% of average weekly earnings, then up to 33 weeks at the lower of 90% or the statutory rate of £184.03 in 2024-25), starting up to 11 weeks before the expected due date. The employer pays SMP through payroll, then reclaims most of it from HMRC via the EPS — small employers (Class 1 NIC under £45,000 in the prior year) reclaim 103%, larger employers reclaim 92%. The MATB1 form has to be received within specific time limits, the SMP1 issued if the claim is rejected, and Keep-In-Touch days have to be tracked correctly to avoid losing entitlement. A payroll specialist handling Harrow SMP claims regularly will know the gotchas; one who only does weekly wages won't.
IR35 / off-payroll working rules don't apply to most Harrow small businesses on the receiving side — only medium and large clients have to assess IR35 status of contractor relationships under the 2021 reform — but they do apply when a Harrow PSC contractor takes on a public-sector or large-corporate client. The deemed employment payment runs through PAYE on the contractor's company, and the payroll specialist has to set up the calculations correctly: deduct PAYE and Employee NIC from the deemed salary, pay over Employer NIC, and reconcile against the corporation tax position so the same income isn't taxed twice. Most Harrow IT, engineering, and management contractors who work with large clients hit this at some point.
Multi-state CIS contractors create a payroll complication: PAYE staff alongside CIS subbies inside one Harrow business. The PAYE workforce runs on the FPS like any normal payroll. The CIS subbies are processed separately on the monthly CIS300 return, with deductions recorded but not via FPS. The accountant has to keep the two streams reconciled at year-end and ensure that any shared expenses (vans, tools, materials) are coded correctly to the right scheme. A trade business growing from sole-subbie operation to running its own PAYE staff will need a payroll setup transition that the matching service can flag at the start of the engagement.
Real-Time PAYE corrections happen more often than most owners expect. An employee's tax code arrives in the wrong format mid-year; HMRC issues a P9 update; a bonus payment was miscoded. The fix is to submit a corrected FPS for the affected period or, in some cases, an Earlier Year Update (EYU) for prior tax years. Where the correction reduces the tax liability, the employee gets a refund through subsequent payroll runs; where it increases it, the employee owes extra. The payroll specialist coordinates with HMRC and the employee on these adjustments. They're routine but easy to get wrong, and getting them wrong creates downstream tax-code mismatches that take months to unwind.
How a real Harrow engagement actually plays out.
Single-director limited company — annual scheme, secondary-threshold salary
A Harrow contractor operating through a personal service company. Director takes salary of £12,570 a year (the personal allowance), with the rest extracted as dividends. The payroll specialist sets up an annual scheme with HMRC, runs a single payroll in March each year reporting the full year's salary, and submits 'no payment due' EPS submissions in the intervening months. Total annual fee: £180. No employer's NIC (below the £9,100 secondary threshold), no employee's NIC (below the £12,570 primary threshold for 2024-25 onwards), but it's a qualifying year for State Pension. Cleanest possible payroll arrangement for a single-director PSC.
Wealdstone construction firm — six PAYE staff plus rotating CIS subbies
A Wealdstone scaffolding company with six PAYE workers (mix of weekly and monthly pay cycles), plus three to five labour-only CIS subcontractors at any time. The payroll specialist runs weekly payroll for the four shift staff, monthly payroll for the two salaried admins, and a separate CIS300 monthly return for subbies. Auto-enrolment is via The People's Pension. The Employment Allowance is claimed at the start of each tax year. The engagement runs alongside the CIS bookkeeping piece — same accountant handles both for consistency. Year-end P60s, P11Ds for the company-car driver, and a tidy CIS reconciliation sit on top.
Harrow Town Centre retail — eight weekly-paid shift workers, statutory absence claim
An independent shop in HA1 with eight shift workers on weekly pay. The payroll runs every Friday for the prior week's hours, with the FPS submitted same-day. Mid-year, one employee goes on Statutory Maternity Pay; the payroll specialist handles the SMP calculation, reclaims 103% via the monthly EPS (small-employer status confirmed), and tracks Keep-In-Touch days. Auto-enrolment via NEST. Year-end P60s issued, no benefits-in-kind so no P11D. Engagement fee covers ~50 payslips a month plus the statutory pay claim and end-of-year work.
The work a matched specialist actually takes off your desk.

- Year-end P60s, P11Ds for benefits in kind, and final EPS
- Director-only payrolls with annual scheme operation
A good fit if you're one of these.
Limited companies with one or more director-employees
Trades and construction businesses with PAYE staff alongside CIS subbies
Hospitality and retail with shift workers on weekly or four-weekly pay
Professional services with monthly salaried staff
Charities and not-for-profits with mixed-status workers
We don't publish fixed £/month tables, and here's why.
Payroll fees scale almost linearly with employee count and pay-cycle frequency. A monthly five-person payroll is materially cheaper than a weekly twenty-person one. Director-only annual schemes are the cheapest engagement type. Auto-enrolment setup is usually a one-off fee on top of ongoing payroll. We won't quote per-employee figures here because they vary too much by complexity (CIS, statutory pay, multiple departments). The accountant quotes after seeing your scheme.
