Payroll & CIS

Everyone paid right, on time, every time

RTI payroll, workplace pensions and CIS deductions handled end to end — so your staff and subcontractors are always paid correctly and HMRC is always filed on time.

Payroll processes your employees' pay, tax and National Insurance, reporting to HMRC in real time (RTI) each pay run. CIS is the Construction Industry Scheme, where contractors deduct tax from subcontractors' pay and report it monthly. We run both accurately, so nobody is paid wrong and no deadline is missed.

The plain-English promise

Pay day, minus the pressure

Payroll looks simple until it isn't. Tax codes change, someone joins mid-month, a pension needs sorting, RTI has to reach HMRC on time, every time. One slip and your people notice immediately — and HMRC not long after. We run it so it's right, quietly, every pay run.

We process your payroll, submit RTI to HMRC, manage auto-enrolment pensions, and produce clean payslips, P60s and P45s when they're needed. If you're in construction, we handle CIS too — verifying subcontractors, applying the right deductions, and filing your monthly returns on the dot.

You approve the numbers, we do everything else. Your team gets paid accurately and on time, your filings land when they should, and pay day stops being something you have to manage at all.

Running payroll and CIS returns for a growing team
Is this you?

Sound like your pay day?

  • Every pay run eats an afternoon you don't really have.
  • Tax codes and starters or leavers leave you second-guessing the figures.
  • Auto-enrolment pension duties feel like a maze.
  • You're a contractor unsure you're verifying subbies and deducting CIS correctly.
  • The monthly CIS return date keeps catching you out.
  • You worry a payroll slip will land you a penalty or an upset employee.

If any of that rings true, payroll and CIS are exactly what we'll lift off your plate.

How it works

Getting you set up in three steps

  1. We set up the scheme

    We register your PAYE and CIS schemes if needed, load your people and subbies, and agree your pay schedule.

  2. You approve, we process

    Each period you confirm hours and changes; we calculate the run, file RTI and CIS, and handle the pension side.

  3. Everyone gets paid & filed

    Payslips go out, HMRC is reported on time, and you know exactly what to pay and when.

Key payroll & CIS deadlines

RTI must reach HMRC on or before each time you pay staff. Your monthly CIS return is due by the 19th of each month, covering the tax month to the 5th, and PAYE or CIS payments are due by the 22nd if paying electronically. Miss a CIS return and HMRC charges an automatic £100 penalty — we make sure that never happens.

Questions, answered

Common questions about payroll and CIS

RTI stands for Real Time Information. It means every time you pay staff, the details — pay, tax and National Insurance — must be reported to HMRC on or before that pay date, not once a year. It's been compulsory for employers since 2013. We handle every submission for you, so it's always on time and correct.

Under the Construction Industry Scheme, contractors file a monthly return by the 19th of each month, covering the tax month running to the 5th. It lists every subcontractor paid and the tax deducted. Miss it and HMRC issues an automatic £100 penalty, so we file yours well ahead of the date.

Yes — under auto-enrolment, every employer must assess their staff and enrol those who qualify into a workplace pension, contributing on their behalf. The duties are ongoing, not a one-off. We assess your team, set the scheme up, and manage the enrolment and re-enrolment so you stay compliant.

If you work as a subcontractor, contractors deduct tax from your payments — usually 20% if you're verified, or 30% if not — and pass it to HMRC. That's often more than your actual liability, so you can reclaim the difference. We track your deductions and recover any overpaid tax for you.

Switching over was painless — they sorted everything with our old accountant. Now we actually get told about tax bills in advance instead of the week they're due.
