Wealth Surcharge, Explained: The 4-Crore Line and the Two-Car Trigger
The surcharge (সম্পদ সারচার্জ) is not a wealth tax. It is a percentage added to the income tax of taxpayers whose declared net wealth passes ৳4 crore — and its two triggers mean some people pay it at far lower wealth than the headline suggests.
The bands
| Declared net wealth | Surcharge on the tax |
|---|---|
| Up to ৳4 crore | Nil |
| Over ৳4 crore to ৳10 crore | 10% |
| Over ৳10 crore to ৳20 crore | 20% |
| Over ৳20 crore to ৳50 crore | 30% |
| Over ৳50 crore | 35% |
“Net wealth” is the figure in the statement of assets and liabilities filed with the return (section 167 of the Income Tax Act 2023): assets at acquisition value, minus liabilities. The surcharge is charged on the tax payable after the investment rebate — so a bigger rebate shrinks the surcharge too, and the minimum tax is not surcharged in these workings because at incomes where the minimum tax rules, net wealth of ৳4 crore is rarely in the picture.
The two triggers
Owning more than one motor car, or house property over 8,000 square feet in total, sets the surcharge rate to 10% whatever the net wealth — including net wealth well below ৳4 crore. The logic is anti-avoidance: without the triggers, a taxpayer could hold conspicuous assets while declaring net wealth a taka under the line. With them, the visible assets speak for themselves.
The worked example
Total income ৳50,00,000 produces slab tax of ৳11,10,000 (30,000 + 60,000 + 1,00,000 + 5,00,000 + 30% of the remaining ৳14,00,000 = 4,20,000). With net wealth of ৳6,00,00,000, the surcharge is 10% of the tax — ৳1,11,000 — taking the total to ৳12,21,000. With ৳10,00,000 of tax already paid at source, the amount still to pay is ৳2,21,000. Every one of those numbers is an acceptance test in the surcharge calculator and the flagship.
Surcharge questions
Does the surcharge apply to companies too?
This page covers the individual surcharge under section 18(4) of the Income Tax Act 2023. Company taxation has its own rate schedule and conditions and is outside what TaxHisab calculates.
What is the environment surcharge I have heard about?
A separate levy in the same schedule, charged on owning more than one motor car, graded by the car’s cubic capacity and collected around registration and fitness renewal (electric vehicles were exempted from it from assessment year 2026-27). It is not the wealth surcharge: the wealth surcharge rides on your income tax, the environment surcharge rides on the car. Because its amounts depend on the specific vehicle, this site explains it and deliberately does not calculate it.
