The new functionality of interest calculator in GSTR-3B is now live on the GST Poral.

This functionality will facilitate & assist the taxpayers in doing self-assessment. This functionality will arrive at the system computed interest on the basis of the tax liability values declared by the taxpayers, along with the details about the period to which it pertains. The interest applicable, if any, will be computed after the filing of the said GSTR-3B and will be auto-populated in the Table-5.1 of the GSTR-3B of the next tax-period. The facility would be similar to the collection of Late fees for GSTR-3B, filed after the Due date, posted in the next period’s GSTR-3B. This functionality will inform the taxpayers about the manner of system computed interest for each tax-head and hence will assist the taxpayers in doing correct computation of interest for the tax liability of any past period declared in the GSTR-3B for the current tax period.

This functionality will further improve ease of filing return under GST and is, therefore, in the direction of further reducing the compliance burden for taxpayers.

INTEREST CALCULATOR IN GSTR-3B

Introducing Interest calculator

To facilitate taxpayers in doing self-assessment, the new functionality of interest calculator is being released in GSTR-3B. This functionality will assist taxpayers in calculating the interest applicable for delayed filing of returns. Taxpayers will have to verify and discharge the correct interest liability as per law, as payment of interest is a statutory compliance.

Interest computation

The interest computed by the system has been aligned with the Section-50 of the CGST Act, 2017, as amended. Consequently, interest liability for respect of supplies made during the tax-period pertaining to the GSTR-3B being filed will be calculated only on that portion of the tax which is paid by debiting the electronic cash ledger, i.e., net tax paid in cash. However, with respect to the supplies pertaining to the previous tax period(s) being declared in later GSTR-3B, the interest will be computed for the entire liability.

Auto-population of system computed interest

Furnishing tax-period wise break-up in GSTR-3B: The return in FORM GSTR-3B allows taxpayers to discharge tax liability for previous tax-periods also, in addition to the tax liability for the present period. However, the tax-period wise break-up of the tax liability is not available in GSTR-3B.

This new functionality will compute the interest applicable on the basis of the values declared by the taxpayers in GSTR-3B for a particular tax-period assuming that entire liability belongs to that tax period. This system computed interest will be auto-populated in Table-5.1 of GSTR-3B for the next tax-period, the way it is done for the Late fees at present.

The system computed interest values auto-populated in next GSTR-3B return will be kept editable. However, the system generated PDF of filed GSTR-3B will contain both values: the System computed interest, and the user paid interest values.

To enable taxpayers to pay interest on supplies of past periods declared in a GSTR-3B, if any, a new button has been added in GSTR-3B, called ‘Tax Liability Breakup, as applicable’, and data is to be entered by clicking this button only by those taxpayers who are making payment for liability pertaining to earlier tax-periods in the present GSTR-3B. In cases where the present GSTR-3B consists of liability only for the present period, the taxpayers can ignore this button, and continue filing their return as usual.

Changes in user experience

After the interest calculator is enabled on the GST Portal, there will be no change in the user experience for the taxpayers. For those who have filed the previous return after due date, the interest would be auto-calculated and populated assuming that the entire liability pertained to that tax period. The taxpayer would still have the facility to provide the break-up of liability of the past period(s) to pay the correct interest using the ‘Tax Liability Breakup, as applicable’ button.

This facilitation measure is expected to assist the taxpayers by helping them with calculation of correct interest while filing of GSTR-3B and will thus improve ease in filing return under GST.
