At SLONEC we support operators from licence application to export, helping you stay compliant with the National Minerals Agency, the NRA and the EPA while you focus on production.
Whether you are an explorer, a small-scale miner, an exporter or a contractor, the numbers behind your licence matter as much as the ground you hold. Royalties, mineral resource rent tax, annual charges, community development agreements and local content reports all draw on the same records.
SLONEC brings those obligations into one plan: clean books and cost controls on site, tax and royalty computations that stand up to review, and advisory support when you raise finance, enter a joint venture or apply for an export licence.
What investors and operators in Mining & Natural Resources should know about Sierra Leone's rules and reliefs, with the law behind each point.
Licence holders pay royalties and mineral resource rent tax under the Extractive Industries Revenue Act 2018, and income tax under the Income Tax Act 2000 as modified by that Act.
Prospecting and exploration start-up costs attract a 100% capital allowance; development expenditure attracts 40% in year one and 20% a year for the next three years. Losses can be carried forward for up to ten years from commercial production.
Small-scale and large-scale licence holders must agree and implement a community development agreement with the primary host community. The Minister approves a compliant agreement within 45 calendar days.
Holders must give priority to Sierra Leonean goods, services and citizens, run a skills plan and report staffing annually, and repatriate at least 30% of export revenues within three months of export.
From 1 January 2026 the Finance Act 2026 raised the corporate income tax rate for resident companies from 25% to 30%, made every company pay the higher of its normal income tax and the minimum alternate tax (2% of turnover), and abolished the investment allowance.
Checked on 10 October 2026 against the sources listed. Incentives usually have conditions and can change with each annual Finance Act, so speak to SLONEC before you rely on any of them for an investment decision.
