Our payroll solutions

Ensure your staff are paid accurately and on time

We manage end-to-end payroll processing tailored to your workforce size, structure and sector. Our service includes:

  • Gross-to-net calculations, statutory deductions and benefit processing;
  • Payslip generation and Real Time Information (RTI) submissions to HMRC;
  • Year-end reporting and P60s.

Whether you run a simple scheme or a complex payroll, we provide a reliable, accurate and fully compliant service, ensuring employees are paid correctly and HMRC obligations are met without stress or delay.

Maintain compliance for senior and cross-border employees

High earners and internationally mobile staff face unique payroll complexities. We offer expert support to ensure correct tax treatment in both home and host countries.

We assist with:

  • Shadow payrolls for expatriates and secondees;
  • Dual withholding and double taxation risk management;
  • Coordination with global mobility advisers.

Our specialist team ensures compliance with UK and international rules, supports accurate reporting, and reduces the risk of tax inefficiencies for your senior employees and business alike.

Avoid double taxation for cross-border workers

Employees working across borders can face tax in multiple jurisdictions. We help calculate and apply foreign tax credits, so they receive proper relief, and your business stays compliant.

We advise on:

  • Relevant double tax treaty provisions;
  • Tax credit calculations and timing;
  • Accurate reporting within payroll and self-assessment processes.

Our proactive support protects employees from unexpected liabilities and ensures your business meets its obligations without overpaying tax.

Stay compliant and avoid penalties through accurate wage assessments

NMW compliance can be complex, especially for employers with variable hours, shift premiums or salary sacrifice arrangements. We support you with:

  • Reviews of pay structures and risk areas;
  • Calculation of NMW across different employee types;
  • Accurate HMRC reporting.

We help ensure fair pay, reduce risk and support compliance with evolving NMW legislation, so your business remains protected, and your workforce is treated fairly.
