Accurate, RTI-compliant payroll run on time, every pay date.
Zmartly runs your UK payroll end to end: RTI submissions to HMRC on or before every pay date, auto-enrolment pension assessments, and payslips your team can rely on. Your ACCA-qualified accountant handles starters, leavers, statutory pay and year-end so you avoid the late-filing penalties and contribution errors that catch most small employers. Fixed monthly pricing, no surprises.
We file a Full Payment Submission to HMRC on or before every pay date and an Employer Payment Summary where needed to reclaim statutory pay or apply the Employment Allowance (up to £10,500 off your secondary Class 1 NIC bill in 2026/27). Late or missing FPS filings trigger automatic monthly penalties from £100, and we keep you clear of them.
We calculate income tax and National Insurance against the current thresholds: the £12,570 personal allowance and £242/week primary threshold, with employer (secondary) Class 1 NIC at 15% on earnings above the £5,000-a-year secondary threshold. We reconcile your monthly PAYE liability so what you pay HMRC by the 22nd matches what we've reported.
We assess every worker each pay period against the £10,000 earnings trigger, enrol eligible jobholders, and calculate contributions on qualifying earnings (the £6,240-£50,270 band) at the statutory minimum of 8% total, including 3% employer. We manage opt-ins, opt-outs and your three-yearly re-enrolment, and file the Declaration of Compliance with The Pensions Regulator.
We administer Statutory Sick Pay (£118.75 a week for up to 28 weeks in 2025/26, uprated each April) and family leave pay, Statutory Maternity, Paternity, Adoption and Shared Parental Pay at £187.18 a week or 90% of average weekly earnings if lower. We reclaim the recoverable element (92%, or 103% under Small Employers' Relief) through your EPS so you're not out of pocket.
We process new starters from their P45 or starter checklist, issue P45s for leavers, and check every payslip against the National Living Wage of £12.21 an hour (age 21+) to keep you off HMRC's NMW naming list. We handle student loan deductions, attachment of earnings orders, and benefits in kind via payrolling where you've registered.
We complete your payroll year-end, file the final FPS, and issue P60s to all employees by 31 May. We prepare P11D and P11D(b) returns for benefits in kind by 6 July and calculate the Class 1A NIC (15% in 2026/27) due by 22 July. From April 2026 most benefits in kind move to mandatory payrolling, and we'll have you ready for the switch.
You deal with one named accountant who knows your payroll, not a call-centre queue. ACCA-qualified and up to date with each April's rate and threshold changes, so your filings are right first time.
FPS filing on or before pay date is non-negotiable for us, that's what keeps you clear of HMRC's automatic late-filing penalties. We reply to queries within 72 hours so nothing stalls before payday.
Payroll sits within our fixed monthly plans at £99, £199 or £499, no per-payslip surprises and no year-end surcharge. Rolling monthly terms, so you're never locked in, backed by our 30-day money-back guarantee.
We run payroll alongside Xero, QuickBooks, FreeAgent or Sage, syncing wages, PAYE and pension postings straight into your books so your accounts and payroll always reconcile.
Auto-enrolment assessments, contribution uploads, re-enrolment and the TPR Declaration of Compliance are all included, the admin that quietly trips up most small employers, done for you.

Quick and easy integration.
Consistent monitoring and reporting.
A Full Payment Submission (FPS) has to land with HMRC on or before the day employees are paid. Miss that window and HMRC issues a late-filing penalty starting at £100 a month for businesses with 1-9 employees, scaling up by headcount. We run FPS and EPS submissions on the morning of each pay run so the deadline is hit automatically, not chased.
Payroll runs at £4 per payslip per pay run, with no separate setup fee for new starters or leavers. That includes RTI filing, payslip delivery, P45s, P60s, pension contribution files, and HMRC liaison. Most clients fold it into a fixed monthly accounting package rather than paying it as a standalone line.
Yes. Operations teams on weekly, salaried staff on monthly, and directors on annual are common in the same client. Each frequency is set up as its own pay schedule in the payroll software, with separate RTI submissions but consolidated reporting at year end. There is no per-schedule premium.
Yes, and most clients who switch to us do exactly this. We collect year-to-date pay, tax, NI, pension, and student loan figures from your current provider, load them into the new system, and reconcile against your last FPS so HMRC sees a clean continuation. We have done mid-year migrations as late as month 11 with no employee disruption.
Yes - all statutory payments are calculated, processed through the pay run, and reclaimed from HMRC where eligible (small employers can recover 103% of statutory family-leave pay). We track qualifying weeks, average weekly earnings, and notification dates so you do not lose recoveries through missed paperwork.
Thirty minutes with an ACCA-qualified accountant. Most owners uncover £1,000-£3,000 in annual savings on the first call. If we are not the right fit, you walk away with a free tax review on the house.
