Self-assessment tax, also known as ‘SAT’, is a system under which taxpayers can compute and report their own tax liabilities to the Indian government. This type of tax is applicable where taxpayers have multiple sources of income, such as: 

  • Rental income

  • Self-employment income

  • Income from investments and businesses 

  

It is the balance tax that you must pay on the income during a financial year. You need to assess this tax after taking advance tax and TDS into consideration. Self-assessment tax is computed and paid by the taxpayer before the filing of the ITR. Now that you know what a self-assessment tax is, let’s find out why one should pay this tax. 

Why Should You Pay Self Assessment Tax?

Self-assessment tax (SAT) generally applies when you furnish income tax returns under Sections 115WD, 115WH, 139, 142, 148, 153A, and 153BC. If the taxes that you have paid during the financial year missed any key inclusions, you can include them in this final tax payable.  

 

Suppose you are a salaried employee. Every year, your employer deducts TDS from your salary. However, if you earned ₹10,000 for a freelancing project and missed informing, the tax on this income won't get deducted.

 

In such cases, self-assessment tax comes to your rescue. It helps you compare your total tax liabilities with the tax already paid so you can pay the balance. Although there is no specific due date for self-assessment tax, it's advisable to pay it as soon as possible. This will help you avoid any penalties for late payment.

How to Calculate Self Assessment Tax

Before your self-assessment tax payment, you need to determine your total income for the financial year from all the sources. 

 

Next, you should identify any deductions or allowances you may be eligible for. These may include the expenses related to your self-employment charitable donations, or pension contributions. 

 

After calculating your total income from all sources and identifying the applicable allowances or deductions, follow the steps below:

  1. Deduct all the tax exemptions and deductions, such as the investments made u/s 80C, 80D, and several other deductions

  2. Compute the tax applicable on the due amount according to the tax slab rates. This is your total taxable amount

  3. Use the following formula to compute the self-assessment tax: [(X+Y) - (A+B+C+D)]

 

where

X = Total taxable amount

Y = Interest according to Sections 234A/234B/234C

A = Tax relief u/s 89/90/90A/91

B = MAT (Minimum Alternative Tax) credit u/s 115JAA or 115JD

C = TCS/TDS

D = Advance tax 

 

You must note that the interest u/s 234A of the Income Tax Act, 1961, will be paid in case of late filing of the ITR. Sections 234B and 234C will only be applicable in case of late advance tax payment.
