Guide

What is tax deducted at source?

Companies, NGOs, government offices, banks and other withholding entities must keep back part of a supplier's bill and deposit it to the government on the supplier's behalf:

  • VDS (VAT deducted at source) — under the VAT and Supplementary Duty Act 2012 and the VDS rules. For listed services the entity deducts VAT at the specified rate; for goods supplied at a reduced VAT rate, the full VAT on the invoice is deducted.
  • TDS / AIT (income tax deducted at source) — under the Income Tax Act 2023. The rate depends on the nature of the payment: supply of goods, contracts, services, rent, transport and so on.

How the numbers work

For a ৳1,00,000 consultancy bill plus 15% VAT: total bill ৳1,15,000. VDS at 15% = ৳15,000, TDS at 10% of the value excluding VAT = ৳10,000. Net payment to the consultant: ৳1,15,000 − ৳15,000 − ৳10,000 = ৳90,000. The entity deposits ৳25,000 to the government.

After you deduct

  • Deposit VDS and TDS through the treasury / A-challan within the legal deadline.
  • Give the supplier a Mushak-6.6 (VDS certificate) and a TDS certificate.
  • Show VDS in your monthly VAT return (Mushak-9.1) and TDS in the withholding tax return.

Rates change every budget

The defaults here follow the FY 2025-26 TDS and VDS rules. Rates for specific goods differ (for example essential food items, cement and iron products), so every rate in the calculator is editable — check the latest SRO or ask your tax adviser.

FAQ

Frequently asked questions

Is TDS calculated on the amount including VAT?
No. TDS is calculated on the payment excluding VAT when VAT is shown separately on the invoice. The calculator does this automatically.
Do I deduct VDS on goods with a Mushak-6.3 at 15%?
Generally no — at the standard rate the supplier pays the VAT through their return. When goods are supplied at a reduced or truncated rate, the withholding entity deducts the full VAT.
The supplier wants a fixed net amount. How much is the bill?
Switch to "Net the supplier must get" and type the net amount. The calculator grosses it up so that after VDS and TDS the supplier receives exactly that amount.
Who has to deduct tax at source?
Companies, firms, NGOs, government and semi-government bodies, banks, educational institutions and other entities specified by law. Small sole traders usually are not withholding entities.
