Invoice under general parlance vs. tax parlance:

Invoice in simple terms is nothing but a document specifying list of goods sent or services provided and a statement of the sum due against those items. Invoice is often understood as 'proof of sale' but this common understanding is far from the truth.

Invoice is a document recording the terms of an arrangement already entered into either orally or on a paper. An invoice does not bring into existence a sale agreement but merely records the terms of whatever arrangement that may have been entered into by the parties, involving the subject matter.

Most of the Indirect tax laws require the preparation of an invoice which does not mean that the absence of an invoice defeats the levy but prescribes an unambiguous occasion when the tax may become recoverable with a proper record of the terms of the underlying arrangement. Therefore, an invoice can evidence not only a sale but every other form of supply such as transfer, barter, exchange, license, rental, lease or disposal. If issuance of an invoice is uncommon for barter or a rental arrangement, then it is to do with our own unfamiliarity and nothing to do with its impermissibility.

Invoice under GST:

GST requires that a tax invoice or bill of supply to be issued before or on the occurrence of certain event or within a prescribed time. Therefore, an invoice is required for every other form of supply such as transfer, barter, exchange, license, rental, lease or disposal.

GST allows seamless flow of Input Tax Credits (ITC) across the supply chain. One of the fundamental pillars of GST is checking the Input Tax Credit (ITC) Claims, for which data of all Invoices to be uploaded and matched. GST system is backed up by strong IT support from Goods and Services Tax Network (GSTN) for matching such data. GSTN seeks all registered dealers shall file Invoice wise details in order to do such matching.

Tax Invoice:

Every registered taxable person under GST supplying Goods or services is required to issue a tax invoice for all supplies effected. The word "Every registered Taxable person" clearly specifies that issuing Tax Invoice is compulsory under GST law. However, government may notify some other document for certain category of services. E.g. Bus ticket, Bank Voucher etc.,

Bill of Supply:

A supplier supplying exempted goods or service or a supplier who has opted for composition levy scheme has to issue a bill of supply instead of a tax invoice. A bill of supply is not eligible for claiming input tax credits.

What's new under GST?

Under GST along with Tax Invoice the concept of Bill of supply is brought in. Bill of supply is issued by a composition tax payer and a registered taxable person in case of supply of Exempt goods or supplies.

The provision to issue revised invoice (from the effective date of registration to the date of issuance of certificate) is not available at present. This document would be useful for claiming tax credit for supply of goods/services during this period.

At present, invoices or bills of sale etc. can be issued inclusive of tax in certain cases whereas it is mandatory to indicate the tax charged in the GST regime.

Self-invoice to be prepared on the date of receipt of supply, which is liable to tax under reverse charge, from an unregistered person. Such Invoice sequence numbers to be reported along with GSTR-1 as per published draft formats.

Rectification of an error in an Invoice:

• Revised Invoice will be issued for correcting clerical errors or typographical errors.

• Credit Note will be issued in case of increase in taxable value and increase in tax rate

• Debit Note will be issued in case of decrease in taxable value and decrease in tax rate
