Before you start

A Taxpayer's Identification Number (TIN) from the NBR
A day count against the 1 July–30 June income year
Salary certificates and records of any foreign income
A Bangladeshi bank account

Step-by-step

1
Do the day count properly — 182 days, two limbs, July to June
You are resident if present for 182 days or more in the income year, or 90 days or more in the income year if you were present for more than 365 days across the four preceding years. The year runs 1 July to 30 June. All three elements differ from the common assumption, and residence turns purely on presence regardless of your residency elsewhere. Academics on repeated semester-length visits should look hard at the second limb.

2
Obtain a TIN
Registration is done through the NBR's e-TIN system. Employers and universities generally require it, banks ask for it, and it is the precondition for filing anything.

3
Establish which Rajshahi taxes zone and circle holds your file
Income tax is national but administration is zonal, and your circle follows your address or your employer. From a city 250 kilometres from the capital this matters more than it would in Dhaka, because at departure the clearance certificate has to be obtained here in person. Find out in your first months rather than your last.

4
Understand the non-resident flat rate before you plan your days
Non-residents are taxed at a flat rate on Bangladesh-source income rather than on the progressive scale that applies to residents. Depending on your income level, crossing or not crossing the residency threshold can move the answer significantly either way. Model it rather than assuming residence is worse — a pattern of repeated academic or project visits makes this a live question.

File the annual return
Returns are filed with your local tax circle under the Income Tax Act 2023, with e-filing increasingly available. An employer's withholding does not remove the individual filing obligation.

6
Start the tax clearance certificate six to eight weeks before permanent departure
A person not domiciled in Bangladesh may not leave without one. For a permanent departure that means filing a return covering 1 July to the departure date, with estimated income to departure included, and obtaining the certificate from your own Rajshahi circle. It requires your presence and it cannot be done in Dhaka on the way to the airport.

Things most newcomers don’t know

The threshold is 182 days, not 183, and the second limb is written for exactly the people who come here.

Bangladeshi residence turns on presence of 182 days or more in the income year, or 90 days or more in the income year where you were in Bangladesh for more than 365 days across the four preceding years. Rajshahi's foreign population is disproportionately academic and research staff on repeated semester- or season-length visits — the exact pattern the four-year test catches. Assuming non-residence because no single year reached 182 is the error to avoid.

There is no city or provincial income tax anywhere in Bangladesh.

People arriving from federal or devolved systems reasonably ask what the local layer costs, because elsewhere it is real money that varies city to city. In Bangladesh it does not exist: income tax is wholly national under the Income Tax Act 2023, and Rajshahi, Dhaka, Chattogram and Khulna are identical on rate, threshold and year. Only the administering zone and circle differ — which is a purely bureaucratic fact, but a consequential one at departure.

From 250 kilometres away, 'the certificate comes from your own circle' is a logistics problem.

The law provides that a person not domiciled in Bangladesh shall not leave without a tax clearance certificate from the income tax authority — an exit return covering 1 July to your departure date, filed at your local tax circle, requiring your physical presence. For a Rajshahi resident that means completing it here before travelling, when the instinct at the end of a posting is to hand over, pack, and sort the paperwork in the capital. That instinct costs weeks.

The flat non-resident rate means residence is not automatically the worse outcome — model it.

Non-residents are taxed at a flat rate on Bangladesh-source income while residents face the progressive scale. Depending on your income level and the shape of your foreign income, either can be better. On an academic salary the resident position is sometimes the more favourable one, which is not the assumption most people arrive with.

Common mistakes to avoid

Carrying a 183-day, calendar-year assumption from another country.
Missing the 90-day second limb after several semesters of shorter visits.
Not knowing which Rajshahi taxes zone and circle holds your file until you need the exit certificate.
Planning to sort the clearance certificate in Dhaka on the way to the airport.
Assuming an employer's withholding removes your filing obligation.
