TIN Number: Overview, How To Apply, State Codes & Documents Required

Businesses established in India or those that sell their goods and services in India are also required to pay tax on their income. Moreover, they are required to have a Taxpayer Identification Number, called TIN or TIN number in short, which identifies them as a taxpaying entity. Let’s understand the concept of TIN and its other aspects in detail.

What is a Taxpayer Identification Number?

The Taxpayer Identification Number (TIN) is an 11-digit, unique identification number. The first nine digits are a unique code while the last two digits are the State-specific digits. The TIN number is allotted by the commercial tax department of every State to businesses and dealers that sell goods and services in India. The TIN number helps the tax department identify every business or company that is registered under VAT.

How does TIN work?

Businesses are required to provide their TIN numbers on different types of tax forms and returns. The income tax department has created the ‘Tax Information Network’ to monitor and track the tax-related details of every business. The TIN number helps the department to identify and authenticate businesses so that there are no fraudulent entities. Moreover, businesses can file their taxes easily by providing the TIN and also claim tax benefits.

Why is TIN needed?

The TIN number is needed for the following reasons

  • It helps the income tax department identify business entities easily
  • The tax-related details of all eligible business entities can be found on a unified portal with the help of the TIN

  • TIN allows businesses to sell their goods and services in India
  • TIN is needed to be mentioned on the tax filing documents of the business for ease of identification

Ways to save taxes

There are ways in which you can save taxes to bring down your tax liability. Some of these ways are as follows

  • Invest in a life insurance policy. Besides availing financial protection against premature death, you would also be able to save taxes. The premiums that you pay would be allowed as a tax-deductible expense, up to INR 1.5 lakhs. The death benefit would be tax-free. The maturity benefit too would be tax-free under Section 10(10D) subject to certain terms and conditions.
  • Invest in a health insurance plan. The plan would also provide financial protection in the case of medical emergencies. Moreover, the premium paid would give you a deduction under Section 80D. You can claim deductions up to INR 1 lakh if you buy policies for yourself and your parents and the insured are senior citizens under both cases.
  • Invest in an ELSS scheme. It is a mutual fund scheme that allows good returns and also helps you save taxes under Section 80C on the invested amount. The limit, however, is INR 1.5 lakhs.
  • You can also explore other tax-saving avenues permitted under Section 80C like PPF, EPF, 5-year deposits, SSY, SCSS, etc.
  • Opt for a home loan and move into your home. The principal that you repay for the loan is allowed as a deduction under Section 80C. The interest, on the other hand, is allowed as an exemption under Section 24(b) up to INR 2 lakhs. Additionally, if you fulfil some conditions, you can claim an additional deduction of up to INR 1.5 lakhs on home loan interest expenses.
