How to calculate Tax & VAT from Contractor Bill?

(ii) Bill or invoice amount or
(iii) payment.
Let’s see some practical examples;
Example-1 Determine the base amount?
- contract value = tk. 6,000,000
- Bill amount = tk. 3,200,000
- Payment = 3,100,000
Here contract value is higher, base amount is tk. 6,000,000.
Example-2 Determine the base amount?
- contract value = tk. 6,000,000
- Bill amount = tk. 6,200,000
- Payment = 5,100,000
Here bill amount is higher, base amount is tk. 6,200,000.
Example-3 Determine the base amount?
- contract value = tk. 6,000,000
- Bill amount = tk. 6,100,000
- Payment = 5,100,000 (After adjustment of old machinery tk. 1,200,000)
Here payment amount is higher because total payment tk. (5,100,000 + 1,200,000) tk. 6,300,000 (base amount)

Step-3 Calculate Tax Amount from Base Value.
Tax = Base Value x Rate of Tax
= 24,106,200 x 7%
= tk. 1,687,439
Step-4 Calculate Payment Amount.
Payment = Base Value – Tax
= 24,106,200 – 1,687,439

VAT = 500,000 x 7.5/107.5 = tk. 34,884.

Term: Tax & VAT as per Government Policy
Calculation Process
At First, we have to find out VAT amount
Step-1 Calculate VAT Amount.
Bill Amount = tk. 500,000
VAT = 500,000 x 7.5/107.5 = tk. 34,884.
So, you must deduct VAT tk. 34,884.
Step-2 Calculate Base Value.
Base Value = Bill Amount – Value Added Tax
= 500,000 –34,884.
= tk. 465,116
Step-3 Calculate Tax Amount from Base Value.
Tax = B = {the selling price of the company to the distributor or the other person as referred in section 94} x 7% x 5%.
Tax = Base Value x Rate of Tax
= 465,116 x 7% x 5%
= tk. 1,628
This amount will be treated as B = the amount of tax applicable under this section if no tax were paid under section 94 = tk. 1,628
Now we have to calculate “A = the amount of tax paid under section 94” from bill of entry
TDS as per 94 = A = Selling price Distributor after VAT x 5% x 5%
Tax = Base Value x Rate of Tax
= 465,116 x 5% x 5%
= tk. 1,163
Here A = the amount of tax paid under section 94 = tk. 1,163
B-A = 1,628 – 1,163 = tk. 465 tax.
So, TDS required for Deduction
Step-4 Calculate Payment Amount.
Payment = Base Value – Tax
= 465,116 – 465
= 464,651
