Methods for computation of VAT
1. Addition Method or Income Approach
i. Aggregate all factor payments (like wages, rent, interest etc.) including profits to arrive at the total value addition.
ii. Apply the rate of VAT on the aforesaid amount to calculate the tax.
2. Subtraction Method or Product Approach
Determine Value addition from either of the following methods:
i. Direct Subtraction method
Total value of sales
Less: Total value of purchases
(both exclusive of tax)
ii. Intermediate subtraction method
Total value of sales
Less: Total value of purchases
(both inclusive of tax)
Apply the rate of tax on the amount calculated in step 1
3. Invoice Method or Tax Credit Method or Voucher Method
i. Compute the tax to be imposed at each stage of sales on the entire sale value
ii. Set-off the tax paid at the earlier stage. (i.e., at the stage of purchases in set-off)
iii. The differential amount (i.e. Step 2 – Step1) is required to be paid
