The Solomon Islands is an archipelagic nation in the South Pacific, with an economy supported by natural resources (logging, fisheries, minerals), subsistence agriculture, and a growing public sector. For international employers, the payroll framework is administered by the Inland Revenue Division (IRD) of the Ministry of Finance for income tax and the Solomon Islands National Provident Fund (SINPF) for mandatory retirement savings. Labour relations are governed by the Labour Act and the Employment Act, which together set minimum standards for wages, working conditions, leave, and termination.

Payroll outsourcing in Solomon Islands provides international organisations with a reliable route to compliant local hiring without entity establishment, managed by providers familiar with IRD PAYE requirements, SINPF contribution obligations, and Solomon Islands employment law. This guide outlines the key regulatory framework and the benefits of specialist outsourcing.

What is Payroll Outsourcing in the Solomon Islands?

Solomon Islands payroll outsourcing involves engaging a specialist third-party provider to manage employee wage calculations, PAYE income tax withholding and remittance, SINPF contribution administration, payslip generation, and all associated statutory filings. For companies without a registered Solomon Islands entity, an employer of record (EOR) arrangement enables compliant employment with the EOR acting as the legal employer under Solomon Islands law.

The SINPF contribution framework — with a significant employer component — makes total employment cost management an important consideration alongside income tax compliance. A specialist provider integrates both into a single payroll workflow.

Regulatory Framework for Payroll in the Solomon Islands

Income Tax (PAYE)

Personal income tax in the Solomon Islands is levied under the Income Tax Act, administered by the Inland Revenue Division. The PAYE system is progressive, with rates ranging from 11% on the lowest taxable band up to 40% on the highest. A personal allowance applies, below which no tax is payable. Employers must register with the IRD, withhold PAYE from employee salaries, and remit the collected amounts monthly by the 21st of the following month. Annual employer returns must be filed with the IRD.

SINPF Contributions

The Solomon Islands National Provident Fund is the mandatory defined-contribution retirement savings scheme. Employer contributions are set at 7.5% of the employee’s basic wage, with employees contributing 5%. Contributions are remitted monthly to the SINPF. Employers must register with the SINPF, enrol all eligible employees, and ensure contributions are paid accurately and on time. Upon reaching retirement age or meeting other qualifying conditions, members may access their accumulated SINPF balance.

Labour Act, Employment Act, and Working Hours

Employment relations in the Solomon Islands are governed by the Labour Act (Cap. 73) and the Employment Act (Cap. 74). The standard working week is 45 hours (9 hours per day, 5 days per week). Overtime is payable at 1.5× the regular rate for hours worked beyond the normal working period and at 2× for work on public holidays. Employment contracts must be in writing for engagements exceeding three months and must comply with the Acts’ minimum standards for remuneration, leave, and termination.

Leave Entitlements

Employees who complete at least one year of continuous service are entitled to a minimum of 15 working days of paid annual leave per year, with additional leave accruing for longer service. Maternity leave of 12 weeks is available to eligible female employees. Sick leave entitlements are governed by the Employment Act and the terms of the individual contract. Public holidays are observed in accordance with the official Solomon Islands government calendar.

Work Permits for Expatriates

Foreign nationals employed in the Solomon Islands require a work permit issued by the Ministry of Commerce, Industries, Labour and Immigration. Work permits are granted for a fixed term and must be renewed before expiry. Employers must comply with localisation requirements and demonstrate that the role cannot be filled by a qualified Solomon Islander before a work permit for a foreign national will be approved. This process requires advance planning and should be managed in parallel with payroll setup.

Employer Filing and Reporting Obligations

  • Register with the Inland Revenue Division (IRD) as a PAYE employer before the first payroll run
  • Withhold PAYE from employee salaries monthly and remit to the IRD by the 21st of the following month
  • File annual employer PAYE returns with the IRD
  • Register with the Solomon Islands National Provident Fund (SINPF) and remit employer (7.5%) and employee (5%) contributions monthly
  • Enrol all eligible employees with the SINPF upon commencement of employment
  • Pay overtime at 1.5× the regular rate (normal OT) and 2× for public holiday work
  • Administer annual leave of at least 15 working days per year for employees completing one year of service
  • Obtain and maintain valid work permits for all expatriate employees
  • Issue payslips showing gross pay, PAYE deduction, SINPF contribution, and net pay

The IRD and SINPF both impose penalties for late or incorrect submissions. Work permit non-compliance carries significant sanctions including deportation of the foreign national and penalties for the employer. All permit applications should be initiated well in advance of the employee’s start date.

Common Payroll Challenges for International Employers in the Solomon Islands

The Solomon Islands’ geographic dispersion across hundreds of islands creates practical challenges for payroll funding and banking, particularly for employers with workers outside Honiara. Cross-border fund transfers can experience delays, and the pool of specialist payroll providers in-country is limited. International employers must rely on regional Pacific providers or global EOR partners with in-country capabilities.

Benefits of Payroll Outsourcing in the Solomon Islands

A specialist provider manages IRD PAYE compliance, SINPF contributions, and Labour Act obligations within a single workflow — eliminating the need for in-house Solomon Islands statutory expertise. The EOR model is particularly valuable for organisations entering the Solomon Islands market without a local entity, enabling compliant hiring within weeks and avoiding the time and cost of entity registration and work permit processes for the employing entity.

Choosing a Payroll Outsourcing Partner in the Solomon Islands

Prioritise providers with Pacific Islands experience, active IRD and SINPF registrations in the Solomon Islands, and established local banking relationships for reliable contribution remittances. Assess the provider’s experience with work permit and localisation compliance, its ability to manage payroll for both local and expatriate employees, and the quality of English-language payslips and employee communications.

Entity Setup vs. Payroll Outsourcing in the Solomon Islands

Establishing a foreign-owned company in the Solomon Islands involves registration with the Foreign Investment Board, incorporation with the Registrar of Companies, and compliance with local equity requirements in some sectors. The process can take two to four months for foreign entities. For organisations with a small or project-based workforce, the EOR model provides a significantly faster and more cost-effective route to compliant employment.

Termination and Final Pay in the Solomon Islands

Upon termination, employers must provide notice in accordance with the Employment Act or pay compensation in lieu. Employees dismissed for redundancy are entitled to severance pay based on length of service. Final pay — including outstanding wages, accrued annual leave, and applicable severance — must be settled promptly. SINPF contributions must be brought fully up to date at the point of termination. All termination documentation should be retained in case of a labour tribunal claim.
