Senegal follows a calendar tax year, running from January through December. For businesses, staying compliant means coordinating annual declarations, monthly reporting and payment deadlines well before accounts are finalised.
Annual Returns and Supporting Accounts
By 30 April following the relevant tax year, companies must submit their corporate income tax return, disallowable expenses declaration, simplified transfer pricing return, local economic contribution declaration based on added value, and financial statements.
An earlier deadline applies to three annual summaries. By 31 January, employers and businesses must report the previous year’s payroll taxes, payments for services and rental payments. These submissions accompany a wider compliance calendar covering annual obligations, including the local economic contribution on rental value and company vehicle tax, alongside monthly VAT, payroll and withholding tax declarations.
Corporate Income Tax Payments
Established companies settle corporate income tax through two advance payments and a final adjustment. Each advance equals one third of the preceding year’s tax liability. The first falls due on 15 February, while the second must reach the authorities by 30 April. Any remaining liability is payable by 15 June.
Newly incorporated businesses receive different treatment during their first financial year. They make no advance payments for that period and instead settle the entire corporate income tax liability before 15 June of the following year.
Consequences of Missing Deadlines
When a taxpayer voluntarily corrects an overdue payment, the charges comprise an initial 5% late payment interest, followed by an additional 0.5% for every month or part of a month outstanding.
Different penalties apply when an audit prompts payment after the deadline. VAT and withholding tax attract a 50% penalty. For corporate income tax, business licence tax, property taxes, registration duties and company vehicle tax, the penalty is 25%. Separately, submitting a return late attracts a fine of XOF 200,000 for each return concerned.
How Tax Reviews Proceed
A request for information, explanations or supporting evidence normally requires a response within 20 days. Authorities may also inspect accounting records at business premises. Another suitable location can be requested where practical circumstances justify it. Notice must arrive at least five days before the inspection begins.
An inspected period generally cannot undergo another inspection unless fresh information or documents emerge. Where officials identify shortcomings, they issue a proposed reassessment. The business then has 30 days to respond. After receiving those observations, authorities have 60 days to uphold the reassessment, either fully or partly.
The 2024 Finance Law additionally restricts remote audits covering taxes and periods already reassessed through an on-site audit; breaching this protection can invalidate the procedure. Nevertheless, the control mechanisms under Articles 571, 576 and 577 of the General Tax Code remain available during the on-site audit period.
Assessment Window and Review Priorities
The usual limitation period is four years. Audit priorities vary by industry, but frequently include deductions subject to restrictions or exclusions. Depreciation, provisions, financing charges, royalties, service fees, insurance premiums and head office allocations commonly receive attention.
Transfer pricing is another growing focus, with supporting documentation requested during inspections. Implementation of BEPS Action 13 is expected to increase scrutiny of arrangements between related businesses, making clear records particularly valuable when explaining how transactions were priced and why deductions were claimed for tax purposes.
