Tax compliance in Bangladesh is not a once-a-year event. Between corporate income tax, VAT, withholding tax and statutory filings, a company touches the National Board of Revenue (NBR) almost every month. Missing a deadline rarely stays a small problem - disallowed expenses, penalties and interest compound quickly.
This guide sets out what a business operating in Bangladesh needs to keep on its 2026 compliance calendar.
1. Corporate Income Tax
Bangladesh applies different corporate rates depending on the type of entity - non-listed companies, listed companies, banks and financial institutions, tobacco and mobile operators are all treated separately, and a reduced rate is available to companies that meet the prescribed bank-transfer conditions for receipts and expenses.
Two practical points matter more than the headline rate:
- Bank transaction conditions - to qualify for the lower rate, receipts and payments above the prescribed threshold must move through banking channels. Cash-heavy operations quietly lose the concession.
- Minimum tax on gross receipts - a loss-making company still pays. Budgeting on the assumption that a loss means zero tax is a common and expensive error.
2. Income Tax Return Deadlines
Companies file by Tax Day, the fifteenth day of the seventh month following the end of the income year. For a June year-end, that is 15 January. Individuals file by 30 November. Extensions are possible on application but do not stop interest from accruing on unpaid tax.
3. Withholding Tax (TDS and VDS)
Withholding is where most audits find problems. Payments for supplies, contractor services, professional fees, rent, salaries, commission and imports all carry deduction obligations at source, and the burden sits with the payer.
- Deposit deducted tax to the government treasury within the prescribed time
- File monthly withholding statements
- Issue certificates to the deductee
Failure to deduct does not shift liability to the recipient - the paying company becomes liable for the tax itself, and the expense is disallowed when computing taxable income.
4. VAT Registration and Monthly Returns
Under the VAT and Supplementary Duty Act 2012, businesses crossing the registration threshold must hold a Business Identification Number (BIN). Registered entities file Mushak 9.1 monthly, by the 15th of the following month, and must maintain the prescribed records - Mushak 6.1 (input-output coefficient), 6.2 (VAT invoice), 6.3 (challan), 6.6 (VDS certificate) and the purchase and sales registers.
A nil return is still a return. Non-filing months attract penalties even where no transactions occurred.
5. VAT Deduction at Source
Specified service categories require the recipient of the service to withhold VAT and issue a Mushak 6.6 certificate. Government bodies, NGOs, banks, limited companies and educational institutions are all withholding entities - which means most B2B service purchases carry a VDS obligation.
6. Annual Statutory Filings Beyond Tax
- Audited financial statements signed by a practising chartered accountant
- Annual return and Schedule X filed with RJSC within the statutory window after the AGM
- Trade licence renewal with the City Corporation
- Fire licence, factory licence and environmental clearance renewals where applicable
7. Penalties for Getting It Wrong
Late filing draws a penalty plus monthly delay interest on the unpaid amount. VAT non-compliance can trigger fixed penalties per offence, interest on arrears, and in serious cases suspension of the BIN. Undocumented expenses are simply disallowed, which raises taxable income even where the spend was genuine.
