Ghana VAT calculation

VAT and statutory levies

Move in either direction between a taxable value and a tax-inclusive invoice. Add CST and Tourism Levy where the transaction legally attracts them.

Classify the transaction before selecting a levy. Zero-rated, exempt and relief supplies require legal classification before any rate is applied.

Ghana withholding calculation

Income-tax withholding and VAT withholding

Select the recipient and payment category, identify the invoice basis, and separate income-tax WHT from the distinct 7% VAT-withholding mechanism.

Related contracts are aggregated for the resident GHS 2,000 contract threshold. The invoice working keeps CST, VAT, levies, income-tax WHT and WHVAT separate.

2026 social-security calculation

SSNIT and Tier 2 contributions

Calculate the employee deduction, employer contribution, SSNIT remittance and Tier 2 allocation from monthly basic salary using the official 2026 minimum and maximum insurable earnings.

This is the mandatory contribution model for a covered worker. Exemptions, multiple employments and voluntary contributions require separate review.

Technical guide: Ghana pensions and retirement tax

Act 766 pension calculation

SSNIT old-age pension estimate

Estimate the Tier 1 monthly pension from the average of the member's best three annual salaries, contribution months and retirement age.

This estimates the SSNIT Tier 1 pension only. It does not apply the full-pension age rules for qualifying hazardous employment. Tier 2 and Tier 3 benefits depend on the member's scheme and fund value.

2026 Ghana tax calendar

Compliance deadline finder and annual calendar

Find one statutory date or build the complete 2026 tax calendar, including monthly obligations, annual filings, quarterly levies and company-year-end deadlines.

The 2026 dates are maintained in the MSL Business School tax calendar. Applicable taxpayer status and special filing directions must still be checked.

Revenue Administration Act calculation

Late-payment interest and late-filing penalty

Calculate statutory late-payment interest with automatic historical Bank of Ghana rates and monthly compounding, or calculate the fixed-plus-daily late-filing penalty.

The late-payment calculation uses the verified rate effective when each monthly period starts. If the Bank of Ghana changes the rate inside a period, the new rate applies from the next period so the calculation retains the one monthly compounding event prescribed by Act 915.

Ghana capital allowance calculation

Capital allowance schedule

Use a quick pool calculation or build an advanced asset register with first-year prorating, individual vehicle restrictions, disposals, repairs and CSV import.

The advanced result identifies direct repair deductions, capitalised excess, assessable realisation amounts, closing WDV and the cost base used for every straight-line pool.

Calculation method and legal scope

How this Ghana late-payment calculation works

For late payment, the engine applies the Revenue Administration Act formula: 125% of the applicable Bank of Ghana monetary policy rate, compounded monthly for each month or part of a month during which the tax remains unpaid.

The rate history is selected automatically from the due date entered. Where the monetary policy rate changes during the default, the result shows a period-by-period schedule and applies the verified rate at the start of each statutory monthly period.

The calculation starts from the statutory due date and ends on the payment date entered. A disputed liability, payment allocation, extension or statutory exception can require separate legal analysis.

Frequently asked questions

Using the Ghana Tax Penalty and Interest Calculator

What rate does the Ghana late-payment calculator use?

It uses 125% of the Bank of Ghana monetary policy rate applicable to each statutory monthly period in the default.

What happens when the Bank of Ghana rate changes during the period?

The calculator creates a period-by-period schedule. A verified new rate is applied from the next statutory monthly period boundary after it becomes effective.

Does part of a month count?

Yes. The programmed section 71 calculation counts each month or part of a month during which the tax remains unpaid and compounds monthly.

How is the historical rate selected?

The engine selects it automatically from a controlled history supported by official Bank of Ghana Monetary Policy Committee materials.

Can the calculator decide whether a penalty or interest charge is legally due?

No. It computes the selected charge from the facts entered. Liability, extensions, payment allocation and statutory exceptions may require separate review.
