By Payroll has never been a simple task — and for London businesses heading into 2026, it’s set to become even more complex. With tighter regulations, increased digital reporting, and rising employment costs, payroll mistakes can quickly lead to HMRC penalties, staff dissatisfaction, and compliance risks.
At TT Accountancy Services (TTAS), we support London SMEs, startups, and growing companies with compliant, efficient payroll solutions. In this article, we explore the key payroll challenges London businesses will face in 2026 and how to prepare effectively.
Why Payroll Is Becoming More Challenging in 2026
UK payroll is evolving due to:
- Increased digitalisation by HM Revenue & Customs
- Expansion of real-time reporting requirements
- Ongoing changes to employment law
- Rising National Insurance and pension costs
- Greater scrutiny of payroll errors
Businesses that fail to adapt risk financial penalties and reputational damage.
1. Stricter HMRC Compliance and Real-Time Reporting
By 2026, HMRC is expected to rely even more heavily on Real Time Information (RTI) submissions.
The challenge:
- FPS and EPS submissions must be 100% accurate and on time
- Even small errors can trigger automated penalties
- Corrections after submission may attract HMRC attention
How to prepare:
✔ Use reliable payroll software
✔ Reconcile payroll monthly
✔ Work with a payroll professional who reviews submissions before filing
2. Rising Employment Costs in London
Payroll costs are increasing due to:
- Higher National Minimum and Living Wage rates
- Employer National Insurance contributions
- Workplace pension obligations
- Competitive London salary expectations
The challenge:
Businesses must balance compliance with affordability while retaining talent.
How to prepare:
✔ Forecast payroll costs annually
✔ Budget for wage and NI increases
✔ Structure pay efficiently with professional advice
3. Payroll for Hybrid, Remote, and Flexible Workers
London businesses increasingly employ:
- Hybrid staff
- Fully remote employees
- Contractors and freelancers
The challenge:
- Correct employment classification
- PAYE vs contractor tax treatment
- Expense reimbursements
- Managing multiple pay structures
Misclassification can lead to backdated tax and penalties.
How to prepare:
✔ Review worker status regularly
✔ Keep clear contracts
✔ Seek professional guidance on payroll and IR35 risks
4. Increased Risk of Payroll Penalties
In 2026, HMRC is expected to maintain a zero-tolerance approach to payroll errors.
Common penalty triggers include:
- Late RTI submissions
- Incorrect PAYE deductions
- Missing pension contributions
- Inaccurate employee records
How to prepare:
✔ Run payroll checks before submission
✔ Maintain accurate employee data
✔ Outsource payroll to reduce risk
5. Pension Auto-Enrolment Compliance
Workplace pension duties continue to be a major payroll responsibility.
The challenge:
- Correct contribution calculations
- Timely pension submissions
- Managing opt-ins and opt-outs
- Re-enrolment duties
Mistakes can result in fines from The Pensions Regulator.
How to prepare:
✔ Align payroll and pension systems
✔ Review contribution levels annually
✔ Ensure records are audit-ready
6. Data Protection and Payroll Security
Payroll data contains sensitive personal information.
The challenge:
- Data breaches
- Insecure payroll systems

✔ Limit access to payroll data
✔ Work with trusted payroll providers
