The tax period is one of the most operationally important concepts in GST. It determines when returns must be filed, when tax must be paid, and from when interest and late fees begin to run. A business that misunderstands its tax period can miss due dates, incur interest at 18% per annum, pay late fees and face reconciliation problems.
Definition Under Section 2(106) of the CGST Act
Section 2(106) defines tax period as the period for which the return is required to be furnished. GST does not prescribe a single tax period for all taxpayers. The tax period depends on the category of registration and the return being filed.
A tax period is not necessarily the same as a calendar month or a financial year. It is the specific interval for which a particular return or statement must be submitted.
Tax Period for Different Categories of Taxpayers
Regular Taxpayers
For normal registered persons, the tax period is ordinarily a calendar month. Section 39(1) of the CGST Act requires every registered person, other than an Input Service Distributor, a non-resident taxable person, a person paying tax under Section 10, TDS deductor under Section 51 or TCS collector under Section 52, to furnish returns for every calendar month.
- GSTR-1: Monthly return of outward supplies.
- GSTR-3B: Monthly summary return and tax payment.
QRMP Scheme Taxpayers
Registered persons having aggregate turnover up to Rs 5 crore in the preceding financial year can opt for the Quarterly Return Monthly Payment (QRMP) scheme. Under this scheme:
- The tax period for returns is a quarter.
- GSTR-1 and GSTR-3B are filed quarterly.
- Tax is still paid monthly through PMT-06 by the 25th of the following month.
- The monthly payment is a self-assessed liability, and the quarterly GSTR-3B reconciles the payments.
Composition Scheme Taxpayers
A person registered under Section 10, the composition scheme, does not file monthly returns. The tax period is:
- Quarterly: Form CMP-08 is filed quarterly for payment of composition tax.
- Annually: Form GSTR-4 is filed annually.
Input Service Distributor
An Input Service Distributor files Form GSTR-6 monthly. The tax period is a calendar month.
Non-Resident Taxable Person
A non-resident taxable person files Form GSTR-5 for the period for which registration is granted. The tax period is the duration of the registration or the shortened period of validity.
Casual Taxable Person
A casual taxable person generally files GSTR-1 and GSTR-3B for the period of registration. The tax period may be the entire registration period or monthly, depending on the duration.
TDS Deductor and TCS Collector
- TDS deductor under Section 51 files GSTR-7 monthly.
- TCS collector under Section 52 files GSTR-8 monthly.
Why Tax Period Matters
Due Dates
Every tax period has a statutory due date. For monthly filers:
- GSTR-1 is due by the 11th of the following month.
- GSTR-3B is due by the 20th of the following month.
- For QRMP filers, monthly PMT-06 is due by the 25th of the following month, and quarterly GSTR-1 and GSTR-3B by the 13th and 24th of the month following the quarter respectively.
Interest Computation
Section 50(1) of the CGST Act provides that a person who fails to pay tax within the prescribed period is liable to pay interest at 18% per annum for the period of delay. Interest runs from the day after the due date of payment until the actual payment date.
After the retrospective amendment to Section 50, interest is payable only on the net tax liability that remains unpaid after utilising input tax credit. Net tax liability means the amount of output tax minus eligible input tax credit available in the electronic credit ledger.
Section 50(2) provides that a person who wrongly claims excess input tax credit or reduces output tax liability in a return is liable to pay interest at 24% per annum on the excess or undue reduction.
Late Fees
Section 47 imposes late fees for delay in filing returns. For GSTR-3B, the late fee is Rs 50 per day of delay, with Rs 20 per day for nil returns. The late fee is capped under the notification, but continued default can still lead to notice and demand.
Input Tax Credit Cut-Off
The tax period also affects the time limit for claiming input tax credit. Under Section 16(4), ITC for a financial year must be claimed by the due date of GSTR-3B for September of the following financial year or the annual return, whichever is earlier. The tax period of the invoice and the return in which it is reported matter for this limitation.
Practical Example
A regular taxpayer has output tax of Rs 2,00,000 for March and eligible ITC of Rs 1,20,000 in the credit ledger. GSTR-3B is due on 20 April. If the taxpayer files the return on 5 May, interest under Section 50(1) is payable on the net tax liability of Rs 80,000 from 21 April to 5 May at 18% per annum. Late fees also apply.
