A to Z Income Tax Guide for Bangladesh

This A to Z income tax guide is written for people who need the whole picture in one place: a new business owner, a returning NRB, an HR manager, a foreign investor or someone filing for the first time. It explains the vocabulary of Bangladesh income tax in plain English and shows how the pieces fit together, from registration to dispute resolution.

The Income Tax Act 2023 replaced the Income Tax Ordinance 1984, and rates, thresholds and many limits change each year through the Finance Act and NBR orders. We therefore explain concepts rather than quote figures. Each section links to a detailed page on our site where you can go deeper or ask us for help.

A to E: the foundations of income tax in Bangladesh

• Advance tax: quarterly instalments payable during the income year when expected liability exceeds the threshold in the Act
• AIT: advance income tax collected at import stage and on certain other transactions, adjustable against final liability in most cases
• Assessment year: the year after the income year in which income is assessed; income from July 2025 to June 2026 is assessed in 2026-27
• Associated enterprise: a related party for transfer pricing purposes, defined by shareholding, control and dependence tests
• Audit: the NBR's examination of a filed return, which may lead to an assessment of additional tax
• Capital gain: profit on sale of capital assets such as land, buildings and shares, taxed under its own rules
• DCT: Deputy Commissioner of Taxes, the officer in charge of a taxes circle
• DTAA: a Double Taxation Avoidance Agreement between Bangladesh and another country
• e-Return: the NBR's online system for filing individual returns and downloading the PSR
• e-TIN: the 12-digit taxpayer identification number issued online by the NBR

F to M: computing your income and tax

• Final settlement: certain TDS, for example on some savings instruments, is treated as the final tax on that income
• Finance Act: the annual law that sets rates, thresholds and changes to the Income Tax Act 2023
• Heads of income: salary, rent from house property, agricultural income, business or profession, capital gains, financial assets and other sources
• Income year: normally 1 July to 30 June; banks, insurers and some financial institutions use the calendar year
• Investment rebate: a reduction of tax for eligible investments, capped by a formula linked to income
• Life-style statement: a statement of family expenditure required from certain individual taxpayers
• Minimum tax: a floor on tax for some taxpayers, often based on gross receipts or on TDS deducted, payable even in a loss year

N to R: residency, returns and records

• NBR: the National Board of Revenue, which administers income tax, VAT and customs
• Non-resident: an individual who does not meet the residency tests; taxed only on Bangladesh-source income at the non-resident rate
• Perquisite: a benefit provided by an employer, taxable as salary income within the rules of the Act
• PSR: Proof of Submission of Return, required for many services such as loans, licences and property registration
• Rebate: see investment rebate; different from a refund, which returns excess tax paid
• Resident: an individual present 183 days or more in the income year, or 90 days or more with 365 days in the preceding four years
• Return: the annual statement of income, tax and, for individuals, assets and liabilities, filed online or at the taxes circle
• Revised return: a corrected return allowed within conditions and time limits in the Act

S to Z: deductions, deadlines and disputes

• Salary certificate: the employer's statement of pay, perquisites and TDS, used in the employee's return
• Statement of assets and liabilities: the wealth statement individuals file to reconcile net wealth with income
• Tax Day: the filing deadline, generally 30 November for individuals and the 15th day of the seventh month after year end for companies
• Taxes Appellate Tribunal: the second-level appeal forum after the Commissioner of Taxes (Appeals)
• TDS: tax deducted at source by the payer on salaries, contracts, rent, interest, fees and many other payments
• Transfer pricing: rules requiring arm's length pricing between associated enterprises across borders
• Withholding return: the periodic return in which deductors report tax deducted and deposited
• Zero return: a return showing no taxable income or no tax payable, still filed to stay compliant and obtain a PSR

How the income tax cycle fits together

For an individual: register for an e-TIN, keep records through the year, let your employer and banks deduct TDS, make eligible investments for rebate, prepare the return after 30 June, reconcile wealth, pay any balance, submit by Tax Day and keep the PSR. If selected for audit, respond with evidence; if assessed unfairly, appeal on time.

For a company: register for an e-TIN, set up TDS on all relevant payments, file withholding returns, pay advance tax, close and audit the accounts, prepare the tax computation and transfer pricing documents where needed, file by the company Tax Day and manage any audit. VAT under the VAT and SD Act 2012 runs alongside this as a separate monthly cycle.

Where people go wrong

• Relying on last year's rates after a new Finance Act
• Holding an e-TIN but never filing, which can create arrears and complications later
• Treating TDS as the whole story and skipping the return
• Not reconciling wealth, so property or savings growth looks unexplained
• Ignoring notices sent to an old address or email
• Missing appeal deadlines after an assessment

How the process works

1. RegisterObtain an e-TIN online using NID or passport details, and for businesses a BIN for VAT where required.
2. Track income and deductionsKeep records of income, TDS certificates, investments and assets throughout the income year.
3. Compute taxAfter the year ends, compute income by head, apply rebate and credits, and check minimum tax.
4. Pay and filePay any balance and submit the return online or at the circle by Tax Day.
5. Keep proofDownload or collect the acknowledgement and PSR and archive the full return.
6. Handle audits and appealsRespond to notices on time and use the appeal or ADR route if you disagree with an assessment.

Typical timeline: The income tax cycle is annual: income year July to June for most taxpayers, individual returns by 30 November unless extended, and company returns by their Tax Day, with TDS, withholding and advance tax obligations running throughout the year.
