Solomon Islands Personal Tax Guide: Progressive PIT 0-40% 2026

Solomon Islands applies a progressive personal income tax (PIT) system with rates of 0%, 10%, 20%, 30%, and 40%. The first SBD 15,000 of annual income is tax-free. Income from SBD 15,001 to SBD 35,000 is taxed at 10%, SBD 35,001 to SBD 50,000 at 20%, SBD 50,001 to SBD 100,000 at 30%, and above SBD 100,000 at 40%. Here is how Solomon Islands personal tax works in 2026.

Individual Income Tax in Solomon Islands is governed by the Income Tax Act and administered by the Inland Revenue Division (IRD) of the Ministry of Finance. The tax year is the calendar year. Residents are taxed on worldwide income, while non-residents are taxed only on Solomon Islands-source income. The progressive system is designed to be equitable, with a tax-free threshold that protects low-income earners. Check residency rules →

Real-world example: An employee earning SBD 60,000 per year pays 0% on the first SBD 15,000 = SBD 0, 10% on SBD 20,000 (15,001-35,000) = SBD 2,000, 20% on SBD 15,000 (35,001-50,000) = SBD 3,000, 30% on SBD 10,000 (50,001-60,000) = SBD 3,000. Total PIT: SBD 8,000. Effective tax rate: 13.3%. For a high earner at SBD 150,000/year: 0% on SBD 15K, 10% on SBD 20K = SBD 2,000, 20% on SBD 15K = SBD 3,000, 30% on SBD 50K = SBD 15,000, 40% on SBD 50K = SBD 20,000. Total PIT: SBD 40,000. Effective rate: 26.7%. Compared to regional peers, Solomon Islands' top rate of 40% is higher than Fiji (20%) but lower than Australia (45%). NPF contributions are separate →

Taxable Income Categories

Solomon Islands PIT applies to several categories of income:

  • Employment income: Salaries, wages, bonuses, allowances, benefits-in-kind — all subject to progressive PIT via payroll withholding
  • Business income: Self-employed individuals and sole proprietors are taxed at progressive PIT rates
  • Rental income: Income from property leasing is taxed at progressive PIT rates after allowable deductions
  • Investment income: Dividends, interest, and royalties have separate withholding tax rates rather than being included in progressive PIT
  • Capital gains: No separate CGT; some speculative gains may be taxed as income

Employment income is subject to monthly withholding by the employer. The employer deducts PIT and NPF contributions before paying the net salary. Employees receive a payslip showing gross pay, deductions, and net pay. Annual filing requirements →

Tax Credits and Deductions

Solomon Islands offers limited tax credits and deductions for individuals:

  • Personal allowance: The SBD 15,000 annual threshold serves as the primary personal allowance
  • NPF contributions: Employee contributions to the National Provident Fund are deductible from taxable income
  • Education expenses: Certain tuition fees and vocational training costs may qualify for deduction
  • Medical expenses: Approved medical expenses may be deductible within limits
  • Charitable donations: Donations to registered non-profits may be deductible up to a percentage of income

Tax deductions generally require documented expenses and are subject to annual limits. The IRD provides specific guidelines on which deductions are allowable.

NPF Contributions (Social Security)

Employees in Solomon Islands must contribute to the National Provident Fund. The rates for 2026 are:

  • Employee share: 5% of gross salary
  • Employer share: 7.5% of gross salary

Contributions are calculated on gross salary. The employer withholds both the employee and employer portions and remits them to the NPF. The contributions fund the provident fund system, providing retirement, disability, and survivor benefits. Detailed social contributions guide →

Who must file a Solomon Islands personal tax return?

Individuals with employment income only (where tax was fully withheld at source) generally do not need to file. Self-employed individuals, those with multiple income sources, or those earning above certain thresholds must file an annual return by March 31. Non-residents with Solomon Islands-source income must also file.

Are bonuses and overtime taxed?

Yes, bonuses, commissions, and additional payments are treated as ordinary employment income and taxed at the progressive PIT rates. There is no special treatment for year-end bonuses, overtime, or performance incentives. Employers include all cash and non-cash benefits in the monthly payroll calculation.

Is there a wealth tax or net worth tax in Solomon Islands?

No. Solomon Islands does not impose a wealth tax, net worth tax, or any annual tax on total assets. Property stamp duty applies on transfers, but there is no tax on total net worth. See the wealth tax guide for details. Wealth tax guide →
