What Is a Tax Invoice?

A tax invoice can be defined as an essential document in financial transactions. It is significant for buyers regarding their claims of input tax credit and is evidence for trade. A tax invoice is extremely important in countries with Goods and Services Tax or others where taxes are charged based on the value of goods and services at each trade stage.

These invoices usually contain the names and address proofs of the buyers and sellers. Significant information like the description of the goods or their quantity is mentioned in them. From due date to payment terms and methods, more additional information can also be mentioned in these invoices.

Businesses must know the tax requirements and invoicing methods to ensure the invoices are compliant. They must also follow correct valuation methods to avoid penalties or fines.

Valuation of Supply Under GST

The GST, or Goods and Services Tax, is a subsume tax for all taxes in the country. It is charged based on the value of goods and services involved in the transaction. Currently, the Goods and Services Tax is charged on the transactional value. It is the cost that is paid for the supply of goods or services in a transaction. The new law has certain rules that must be remembered when determining the supply value for GST. They include –

  • Any duties, taxes, fees, cess, and charges levied under any other act besides GST. If the supplier has separately charged the GST compensation cess, it will be excluded during the goods and services valuation.
  • The transaction value involves all incidental expenses, if present, like commission or packaging.
  • Any amount liable to be paid by the supplier that the recipient has incurred and hasn’t been included in the price.
  • All subsidies associated with the supply other than the Government’s shall be included.
  • Any late fee, interest, and penalty in case of delayed payments shall also be included.

However, discounts and valuation of supply are treated differently under GST. For example, any discount provided before or during the transaction can be deducted from the transaction value. Regarding exports, the applied IGST in the tax invoice will be converted via RBI exchange rates.

Best Practices For Valuing Goods And Services On a Tax Invoice

Valuing goods and services correctly on a tax invoice is critical for a business or an individual. Here is a step-by-step guide to proper valuation on tax invoices. 

  • Supply Valuation Where It Is Not Wholly Money

In such a case, the supply valuation is based on OMV or Open Market Value. The OMV of goods and services is the price you will pay for them without taxes. It exudes any state tax, central tax, union territory tax, etc., that might be added later. Without the open market value, the supply valuation will be based on total monetary consideration and other consideration’s monetary value. If the above-mentioned ways can not determine the value, the kind and quality of goods or services will be considered.

  • When Goods Are Made Or Received Via An Agent

The supply valuation between a principal and its agent will be the OMV of the goods supplied. Or it will be 90% of the supply price of likey quality and kind by the recipient to his customer, who is not a related person, and the goods will be further supplied by the recipient.

  • Supply Valuation Between Distinct Or Related Persons Other Than The Agent

In this case, the supply valuation will be the OMV or open market value, as specified in sections 25(4) and 25(5). If there is no open market value, the supply valuation will be like kind and quality. When clause (a) or (b) cannot determine value, it will be identified by the cost valuation method or residual method.

  • Tax Invoice Valuation By Cost Method

If the above methods cannot find supply valuation, the cost method is your go-to solution. As per this rule, the valuation will be 110 percent of the production cost, manufacturing cost, or acquisition cost of the concerned goods or services.

  • Tax Invoice Valuation By Residual Method

If the cost method is not beneficial in finding the supply valuation, the residual method comes forward. It utilizes reasonable means consistent with the principles and section 15’s general provisions.

Few Special Cases of Supply Valuation

Life Insurance Business Suppose the policy amount is intimated to the holder during service supply. In that case, the gross premium charged from the holder will be lessened by the investment amount or allocated savings on behalf of the policyholder.

Hand Goods

When dealing with second-hand goods, the supply value considered for GST will be the difference between the selling price and the purchase price. If it is a negative amount, no GST will be charged.
Defaulting Borrower When items are taken back from someone who didn’t repay their loans, the value of those items is treated differently. The price that the person originally paid for that item is considered and is reduced by 5% for each quarter or part of a quarter from when they brought the items to when the items are being sold again.

What is Meant By Related Persons?

Persons are referred to as related during the supply valuation under GST if –

  • They are directors or officers of one’s other businesses.
  • Those persons are the employer and employee.
  • They are recognized as legal partners in a business.
  • One of the persons directly or indirectly controls the other one.
  • Any person is in a position to directly or indirectly own, control, or hold 25% or more of the outstanding stock or shares.
  • A third party directly or indirectly controls the two concerned persons.
  • They authorize the third party directly or indirectly or are members of the same family.

What is Meant By Distinct Persons?

Section 25 (5) of the CGST Act says that –

  • If someone has multiple registrations, either in one place or in different places, they will be considered separate individuals for the purposes of this law. In other words, each registration is treated as belonging to a different person.
  • If someone has a business registered in one place and also has a business in another place, the law will consider them as two separate businesses for the purpose of this Act.
