Understanding Output Tax Liability in QRMP

Output tax liability in QRMP refers to the tax that a business needs to pay on its taxable supplies. It is essential for businesses to maintain compliance with GST regulations by accurately assessing their output tax. The process involves several steps that ensure the precision of the tax figures.

Steps for Accurate Tax Calculation in QRMP

Understanding the precise calculation of output tax liability under the QRMP scheme is vital for businesses to ensure tax compliance to manage their financial obligations effectively. Accurate tax calculation helps in avoiding overpayment or underpayment of taxes and ensures smooth cash flow management. Here are the key steps for accurate tax calculation in QRMP, each followed by a more detailed explanation:

  • Identifying Taxable Supplies: The first step involves identifying all the taxable supplies made during the period. This includes all goods and services that are not exempt from GST. It’s crucial to include every taxable transaction to ensure comprehensive tax liability assessment. Regularly updating sales records and categorizing them correctly are essential practices in this step. This process forms the basis of your output tax liability and sets the stage for accurate tax computations.
  • Applying the Correct Tax Rate: Each taxable supply should be categorized according to the applicable GST rate. It is important to stay updated with the latest tax rates for different categories. Applying the correct tax rate is critical to determining the exact amount of tax liability. Misapplication of rates can lead to significant discrepancies in tax calculations, leading to legal and financial complications.
  • Calculating Total Output Tax: After applying the correct tax rates, calculate the total output tax for the period by summing up the tax amount for each supply. The total output tax is a cumulative figure that represents your tax liability for the period. Using accounting software that automatically calculates this figure based on the input data can reduce errors and save time. Regular audits of these calculations are recommended to ensure their accuracy and to correct any discrepancies promptly.

QRMP GSTR-1 Part 2 Tax Liability Computation

The computation of tax liability in QRMP GSTR-1 Part 2 involves a detailed assessment of every transaction. This assessment should be done monthly, even though the return is filed quarterly.

  • Monthly Calculation: Compute the output tax liability for each month, even though the return is filed quarterly. This helps in understanding the tax burden and aids in effective cash flow management.
  • Consideration of IFF: If you are using the Invoice Furnishing Facility (IFF) for B2B invoices, ensure that these transactions are included in your monthly tax liability calculation.

Here’s a consolidated table that shows the process of QRMP GSTR-1 Part 2 tax liability computation, first without and then with the consideration of the Invoice Furnishing Facility (IFF) under QRMP GSTR-1 Part 2:

Month Taxable Sales (Rs.) GST Rate Output Tax Without IFF (Rs.) B2B Sales via IFF (Rs.) GST Rate for IFF Additional Output Tax from IFF (Rs.) Total Output Tax (Rs.)
January 2,00,000 18% 36,000 36,000
February 1,50,000 18% 27,000 30,000 12% 3,600 30,600
March 1,75,000 18% 31,500 40,000 12% 4,800 36,300


  • January: ABC Pvt Ltd calculates its output tax based solely on its regular sales, as no B2B invoices are furnished through IFF.
  • February: The company includes additional B2B sales reported via IFF, adding to the total tax liability for the month.
  • March: A similar approach to February, with different figures for sales and IFF-reported transactions.

This table demonstrates how the inclusion of B2B invoices through the Invoice Furnishing Facility affects the monthly output tax calculation under QRMP GSTR-1 Part 2.
