Everything You Need to Know About Self Assessment Tax

As the citizens of our country, we have to bear and fulfil certain responsibilities, one of which is the timely payment of taxes. Every person is expected to pay tax on their income, and the Government of India may collect these taxes through Self Assessment Tax (SAT) and other taxes such as the advance tax and the TDS/TCS.

This article will take you on a journey of exploring the Self Assessment Tax, along with the answers to some potential questions like why might you need to pay it? How to calculate it? And of course - how to pay for it?

Did you know?

According to the 2021-22 Union Budget, the gross tax revenue of the Indian government is estimated to be Rs. 22,17,029 crores.

What Is Self Assessment Tax?

The Self Assessment Tax may be described as one of the taxes collected by the government of India that a citizen needs to pay for their income from other sources. A Self Assessment Tax is any balance tax to be financed by an assessee on the assessed income at the end of the financial year after evaluating one’s total taxable income, the paid taxes, and the reduction of deductions. 

In layman’s terms, it can be defined as a person's tax liability that stays unresolved until the year’s end, even after TDS payment. Though there is no specific deadline mentioned for the payment of this tax, it is always ideal to pay it at the earliest. Only after this payment is one eligible to file a valid Income Tax return. Failure to pay this tax may lead to the penalty of interest rates on the tax amounts and other consequences.

Self Assessment Tax: Why Would You Pay It?

An individual may be liable to pay off Self Assessment Tax at the end of a financial year based on the following grounds.

  • The tax liability is larger than the sum of the total taxes paid and deducted.
  • It can occur if a person earns additional income in the financial year, like earnings from investments, fixed deposits, or short-term bonds.
  • Another reason may be the deduction of taxes at rates lower than the slab rates pertinent to the assessee.
  • The TDS may not have been deducted or may have been removed partially.
  • Increased tax liability will, in turn, lead to a rise in the tax outflow of the individual.

The neglect in payment of this tax may result in an unsuccessful filing of the Income Tax returns at the end of the year. It may subject the individual to heavy penalties like the government imposing interest rates on the tax amount and other repercussions.

Calculation of Self Assessment Tax

As stated in the definition, the SAT is the pending liable amount after considering the individual's taxable income, the paid taxes, and other deductions. We need to subtract tax credits like TDS, advance tax, TCS, MAT/AMT, credit, and relief mentioned under sections 87A, 90, 90A, and 91. The individual must foot the tax and interest payable under sections 234A, 234B & 234C.  

For calculating your Self Assessment Tax, one may follow the steps mentioned below:

  1. Calculate the total income of the individual.
  2. Calculate the total tax payable on the income as per the applicable slab rates.
  3. Add the amounts of interests disclosed under sections 234A, 234B, and 234C.
  4. Deduct the Relief introduced under sections 90, 90A and 91.
  5. Subtract the amount of Tax Deducted at Source (TDS)/Tax Collected at Source (TCS).
  6. Deduct the amount of Advance Tax paid.
  7. Subtract the amount of MAT credit covered by section 115JAA.
  8. The final amount at the end is the amount of SAT to be paid.

Partially Paid Self Assessment Tax

In the scenario of partly paid SAT, the amount of tax applicable to the assessee has to be initially modified towards the payable interest and levelled towards the tax. The following sample may assist us in understanding this concept better.

Calculation of Interest for SAT

In case the payment of SAT is being made before the evaluation date, and you can figure out the interest through the following methods:

  • The value of the advance tax yet to be paid is taken for computing the interest for the date till the payment of the SAT. 
  • The SAT has to be deducted from the amount of advance tax, considered for calculation from the time of payment of SAT.
