A Tax Invoice is an official document issued by a registered seller to the buyer when goods or services are sold under the Goods and Services Tax (GST) system in India. It serves as proof of sale and includes critical details such as the seller's and buyer's information, GSTIN (Goods and Services Tax Identification Number), invoice number, date, description of goods or services, quantity, rate, taxable value, and applicable GST rates (CGST, SGST, IGST).
Under Indian GST law, issuing a tax invoice is mandatory for every registered business when supplying taxable goods or services. For goods, it must be issued before or at the time of removal or delivery. For services, it must be issued within 30 days from the date of supply.
A tax invoice is not just a billing document—it plays a key role in GST compliance. It allows buyers to claim Input Tax Credit (ITC), which helps reduce their overall tax liability. This makes it essential for both sellers and buyers to maintain proper records of all tax invoices for monthly GST returns and annual filings.
Startups and small business owners should ensure their invoices follow the prescribed format and contain all mandatory fields. Mistakes or missing information can lead to ITC denial or notices from the tax department. Maintaining accurate and timely tax invoices is especially important during business registration, audits, or applying for loans, as it reflects the transparency and professionalism of your business operations.
