Formula

১) করযোগ্য আয় = বার্ষিক আয় − অব্যাহতি সীমা (০-এর কম হলে ০)। ২) দেশে প্রদেয় কর = করযোগ্য আয় × দেশের হার ÷ ১০০। ৩) বিদেশি কর রেয়াত = min(বিদেশে দেওয়া কর, দেশে প্রদেয় কর)। ৪) নিট প্রদেয় = দেশে প্রদেয় কর − রেয়াত।

How the calculation works

Taxable income is the annual income minus the exemption threshold, never below zero.

Home tax is that taxable income at the home rate, and the foreign tax credit is the smaller of the tax already paid abroad and the home tax.

Net payable is the home tax minus the credit, which is why paying tax abroad reduces, but does not always cancel, the home bill.

Common mistakes

When to use it

Worked example

On 1,200,000 income with a 350,000 exemption at 15%, the home tax is 127,500; a 50,000 foreign tax credit leaves 77,500 payable.

Taxable income 850,000.00
Home tax 127,500.00
Foreign tax credit 50,000.00
Net tax payable 77,500.00

Common questions

Can the foreign tax credit be more than the home tax?

No, relief is capped at the home tax on that income, so it cannot create a refund.

Do I need a tax residency certificate?

Most countries ask for proof of foreign tax paid and residency before allowing the credit.
