Payroll and CIS, run together

For a company subcontractor the payroll is the mechanism that turns CIS deductions back into cash. Run it properly and the offset is claimed in the month it arises rather than waiting for the year end.

The offset only works if the payroll is real

For a company subcontractor, payroll is not a separate job from CIS — it is the mechanism by which CIS deductions turn back into cash. The company cannot claim them on its corporation tax return. It offsets them monthly through the Employer Payment Summary, against PAYE due, National Insurance due, student loan repayments due, and the CIS it has deducted from its own subcontractors.

Any excess that cannot be set off may be refunded or set against corporation tax at the end of the tax year, but no repayments or set-offs against other liabilities can be made in-year except where the company is in liquidation or administration. So the practical question is whether you have enough monthly PAYE and National Insurance to absorb what you suffer — and for a labour-only company with a small payroll the answer is usually no.

What an employee costs in 2026/27

The asymmetry is worth noticing: employer National Insurance now starts at £5,000 while the employee pays nothing until £12,570. That gap is new since April 2025 and it changes the optimal salary for an owner-managed company — which is a calculation on your figures rather than a rule of thumb.

Minimum wage from 1 April 2026

BandRate
21 and over — National Living Wage£12.71
18 to 20£10.85
Under 18£8.00
Apprentice£8.00

The apprentice rate applies where the apprentice is under 19, or is 19 or over and in the first year of the apprenticeship. Other 2026/27 statutory rates: Statutory Sick Pay £123.25 a week, and statutory maternity, paternity, adoption and shared parental pay £194.32 a week or 90% of average earnings, whichever is lower.

Sick pay changed on 6 April 2026

The change with money attached

Statutory Sick Pay is payable from day one of absence, for all eligible employees regardless of earnings — the Lower Earnings Limit and the waiting days have both gone. It is paid at 80% of normal weekly earnings or £123.25 a week, whichever is lower. Absences that started before 6 April 2026 follow the old rules.

For a trade business with site staff and a normal pattern of short absences, this is the single largest new payroll cost of the year. Statutory Sick Pay is not recoverable by the employer.

Agency and umbrella labour

From 6 April 2026, where a worker is supplied through an umbrella company, the recruitment agency becomes responsible for accounting for PAYE and Class 1 National Insurance on payments to that worker — and where there is no agency, the responsibility falls on the end client. HMRC can recover PAYE underpayments from them. If you source labour through agencies or umbrellas, that is a recoverable risk sitting on your business rather than somebody else's, and it is worth knowing which of the two you are before it matters.

Quick answers

Frequently asked

What does an employee actually cost in 2026/27?

More than it did. Employer National Insurance is 15% on earnings above a secondary threshold of just £5,000 a year — the rate rose from 13.8% and the threshold fell from £9,100, both on 6 April 2025. The Employment Allowance is £10,500 and the previous £100,000 eligibility cap was removed at the same time, so more employers can claim it. Note the asymmetry: employer National Insurance starts at £5,000 while the employee pays nothing until £12,570. Statutory sick pay is now payable from day one of absence as well, which for a workforce with short site absences is a new and predictable annual cost.

Can my company claim the Employment Allowance?

Not if it has a single director who is the only employee liable for secondary Class 1 National Insurance. Only one company in a group may claim. Off-payroll workers cannot be counted for Employment Allowance purposes, and nor can domestic staff other than care and support workers. For a one-person trade company this restriction usually bites, and it is worth checking rather than assuming the allowance is available. Taking on a first genuine employee often unlocks it, because the director then stops being the only person liable for secondary Class 1 National Insurance.

What changed with sick pay in April 2026?

Statutory Sick Pay is now payable from day one of absence, for all eligible employees regardless of earnings — the Lower Earnings Limit and the waiting days were both removed on 6 April 2026. It is paid at 80% of normal weekly earnings or £123.25 a week, whichever is lower. Absences starting before 6 April 2026 follow the old rules. The government's own costing put the reform at around £400 million a year in extra sick pay across the economy, with most of the increase attributable to removing the waiting days rather than the earnings limit — so for a business with site staff and short absences this is the change with real money attached.

How does payroll help with CIS?

Because a company subcontractor's CIS offset runs through it. The company offsets CIS suffered against PAYE due, National Insurance due, student loan repayments due and the CIS it has deducted from its own subcontractors — monthly, through the Employer Payment Summary. Without a real payroll there is nothing to offset against, so the deductions accumulate until after 5 April. Running the payroll properly and claiming the offset in the month it arises is cash kept now rather than a refund claimed later.
