GST Compliance

What is GST Compliance?

The introduction of the new GST tax system has ushered in major tax reform in the nation. The new system brings together many state and central taxes into one common, fungible tax. This much-needed reform introduced greater transparency and eased administrative paperwork into the tax collection framework. Since its introduction, the new system has been good news for most businesses -- especially for small and medium-sized enterprises that rely on technology to take care of tasks like registration and filing tax returns online.

The new GST regime has introduced compliance guidelines that mandate businesses to remain compliant. All businesses are required to adopt the GST compliance rules set by the government. Although these rules are updated from time to time (based on the requirements set by the govt), these compliance rules can be clubbed into three categories:

Registration compliance
Tax Invoice compliance
Return filing compliance

Additionally, other compliances differ based on the nature of the business.

GST Registration Compliance

The registration of GST is the first step forward in compliance. The registration can be done online on the website – www.gst.gov.in. The process is relatively straightforward; however, there are a few things to keep in mind in order to remain compliant. GST registration must be done based on a businesses’ annual turnover.

Applicable to businesses that deal with the supply of goods and with a turnover exceeding Rs. 40 Lakhs in the previous FY.
Applicable to businesses that deal with the supply of services and with a turnover exceeding Rs. 20 Lakhs in the previous FY.

Businesses that fall under the annual turnover bracket are mandated to register for GST and are liable to other GST compliance requirements. The CBIC (Central Board of Indirect Taxes and Customs) has issued strict penalties for non-adherence to GST registration. The penalty for delay would lead to a fine of Rs. 100 per day. A further delay in GST registration would lead to a fine of Rs. 200. These penalties are as per section 122 of the CGST act non-compliance rules.

Tax Invoice Compliance

Businesses registered under GST must adhere to invoicing compliance to pass on the input tax credit. With every sale of goods or services, businesses are required to produce an proforma invoice as part of their daily business requirements. These invoices must meet compliance rules by including the following mandatory items:

Invoice number and date
Customer name
Shipping and billing address
Customer and taxpayer’s GSTIN
Place of supply
HSN code (Harmonized System of Nomenclature/ SAC Code (Services Accounting Code)
Item details i.e. description, quantity, unit, the total value
Taxable value and discounts
Rate and amount of taxes
Whether GST is payable on a reverse charge basis

Signature of the supplier

For a business to meet invoicing compliance rules, all the items need to be mandatorily mentioned on the GST invoice. Non-adherence of GST invoicing would incur a penalty as high as Rs. 10,000 or 100% tax due (whichever is higher) for not issuing invoice and Rs. 25,000 for incorrect invoicing.

GST Return Compliance

All registered businesses are required to file returns on a monthly/quarterly/yearly basis. The frequency of the returns depends mainly on the type of business activity. The GST returns are required to be filed online on the Returns section of the GST website. Listed below are the forms required to file GST Returns:

GSTR-1 is a return where details of sales are filed with the government. No tax has to be paid after filing this return.
GSTR-3B is a simplified return to declare summary GST liabilities for a tax period. It needs to be self-declared monthly for furnishing summarized details of all outward supplies made, input tax credit claimed, tax liability ascertained, and taxes paid. It is filed by all taxpayers registered under GST.

GSTR-9 return is filed annually by taxpayers under GST, having turnover of over Rs. 2 Crores in the financial year, containing details of outward sales supplies made, inward purchase supplies received during the previous year under various tax heads, and details of taxes payable and paid. It is a consolidation of all the monthly or quarterly returns (GSTR-1, GSTR-2A, GSTR-3B) filed during that year.
