Why 2026 is the hardest year yet for UK payroll
Three changes land in 2026, and each one carries a fine if you get it wrong. Your software will flag the fields. It will not tell you what to do about them.
. PENALITY RISK
From 6 April 2026
Day One Statutory Sick Pay
The three-day waiting period for SSP has gone. Employees qualify from their first day off sick, and the Lower Earnings Limit no longer applies. So more of your team becomes eligible.
We handle it:Â every absence logged correctly and SSP paid in line with the new rules.
. MARGEN RISK
In effect now
Employer NI at 15%
Employer NI now sits at 15% and the secondary threshold has dropped to £5,000, So you pay more on every salary.
We handle it: we claim the full £10,500 Employment Allowance, now that the old £100,000 cap is scrapped, to protect your margin.
. AUDIT RISK
Launches April 2026
The Fair Work Agency
The FWA launches with the power to fine employers over holiday pay, sick pay and record keeping and to name them publicly.
We handle it:Â your payroll records stay audit-ready, so an inspection finds clean books instead of a problem.

Fully managed payroll
We run the whole cycle. You send us hours and changes; we process the pay run, file the FPS on or before payday, pay staff by BACS and send secure payslips. You get a clear summary each period and sign off before anything goes out.
You send hours & changes
We process & you approve
FPS filed with HMRC on time
Staff paid by BACS · payslips sent
SME & startup payroll
New employers usually hit payroll the moment they make their first hire no system, no spare hours. We register you as an employer with HMRC, set up your pay schedule and run everything from day one, so your first payslip is right and on time.
Director-Only Payroll
Most providers treat a single director like a full workforce and miss what matters. We set your salary at the level that works alongside your dividends, keep your NIC record intact and protect your take home pay compliant without overpaying.
Auto Enrolment & Pensions
We handle your workplace pension duties end to end: assessing staff, calculating contributions, filing with your provider and writing to employees when the rules require it. The Pensions Regulator stops being your headache.
International Support UK & UAE
For firms operating across London & Dubai. We bridge the gap. We offer a unified approach to payroll that respects both UK HMRC regulations & UAE labour contexts, providing a single point of truth for your international workforce.

FAQs
Commonly Asked Questions
How much is the Employment Allowance for 2026/27?
For the 2026/27 tax year, the Employment Allowance is £10,500. This allows eligible businesses to reduce their Class 1 National Insurance liability. Notably, the previous £100,000 threshold has been removed, making this allowance available to more employers than ever before.
Does IBISS & CO handle P11D and Benefits in Kind?
Yes. Our team manages the full reporting of expenses and benefits, including company cars, private health insurance, and interest-free loans. We ensure all forms are filed accurately to avoid costly HMRC penalties.
What are the penalties for Fair Work Agency (FWA) non-compliance?
Beginning April 2026, the FWA can issue civil financial penalties for errors in holiday pay, Statutory Sick Pay, and record-keeping. They also have the authority to publicly name non-compliant employers, posing a significant reputational risk.
How does the 2025 Employment Rights Act change Statutory Sick Pay (SSP)?
The Act removes the 3-day waiting period. Effective 6 April 2026, employees are entitled to SSP from their first day of illness (Day One rights). Additionally, the Lower Earnings Limit (LEL) has been removed, expanding eligibility to all workers.
What is RTI and its deadline?
RTI (Real Time Information) is the system HMRC uses to receive payroll data. The legal deadline for an RTI submission is on or before the day you pay your employees. Missing this window triggers automatic compliance flags.
Are there penalties for late or non RTI submissions?
Yes. HMRC issues automatic penalties for late Full Payment Submissions (FPS). Fines typically start at £100 for small businesses (1-9 employees) and rise based on headcount. Continued late payments also incur accruing interest.
Are there any exemptions from RTI?
Very few. Most businesses must report via RTI. Limited exceptions exist for certain care and support workers or those whose religious beliefs prevent the use of computers, but these require formal, prior HMRC approval.
How do I make payroll in the UK or choose a service?
To run payroll, you must register as an employer with HMRC. While basic software can submit data, an advisor-led service like IBISS & CO. ensures tax-efficient planning and compliance with the 2026 legal shifts that basic automated software might miss.
How much do payroll services cost for a small business in London?
You pay a fixed monthly fee based on how many people you pay and how often you run payroll. No hourly billing, no charge per question. Tell us your headcount and pay frequency and we quote a set figure before you commit.
Can you take over payroll from my current provider part way through the year?
Yes. We move your employee data, tax codes and year to date figures across, check them against your next pay run and take over with no gap. Most clients switch mid year without their staff noticing.
Do you run payroll for a single company director?
Yes. We set a director salary that works alongside your dividends, keep your National Insurance record correct and file the RTI submission HMRC requires, even for a one person payroll.
What payroll software do you work with?
We work with the main payroll and accounting platforms, including Xero and QuickBooks, and run the payroll for you on top of them. You get the software’s records plus a human who checks every figure.
