Wealth Surcharge Calculator
The surcharge (সম্পদ সারচার্জ) is a percentage added to the tax of taxpayers whose declared net wealth passes ৳4 crore — or who trip either of two asset triggers at any wealth. Enter your tax and your net wealth; the band, the rate and the amount are worked live.
The bands: net wealth up to ৳4 crore — nil · over ৳4–10 crore — 10% of the tax · ৳10–20 crore — 20% · ৳20–50 crore — 30% · over ৳50 crore — 35%. More than one car, or a house over 8,000 sq ft, forces 10% at any wealth.
Your surcharge rate and amount
The figure from your tax calculation, after the investment rebate. Not sure? The income tax calculator works it out.
The worked example
A taxpayer with total income of ৳50,00,000 has slab tax of ৳11,10,000 (you can reproduce it in the income tax calculator). With net wealth of ৳6,00,00,000 — inside the first band — the surcharge is 10% of the tax: ৳1,11,000, for a total of ৳12,21,000 before credit for tax already paid. The surcharge guide explains the bands, the triggers and the separate environment surcharge on multiple cars.
Surcharge questions
Is the surcharge charged on my wealth or on my tax?
On your tax. Net wealth decides only the percentage: nothing up to ৳4 crore of net wealth, then 10% of your tax up to ৳10 crore, 20% to ৳20 crore, 30% to ৳50 crore and 35% above that. A taxpayer with ৳6 crore of net wealth and ৳11,10,000 of tax pays a surcharge of ৳1,11,000 — 10% of the tax, not 10% of the wealth.
I own two cars but my net wealth is under ৳4 crore. Do I pay?
Yes — owning more than one motor car, or house property over 8,000 square feet in total, triggers the 10% rate whatever your net wealth. The trigger exists so the surcharge cannot be avoided by keeping declared net wealth just under the line while owning the visible assets.
What counts as net wealth?
The total shown in your statement of assets and liabilities filed with the return (under section 167 of the Income Tax Act 2023) — assets at their acquisition value, minus liabilities. It is the declared figure, not a market valuation exercise.
