What is Self-Assessment Tax?

Anyone who earns an income has to pay income tax to the government of India. You might have to bear the consequences if you fail to pay taxes in full. The Self-Assessment tax, also known as SAT, is a type of tax where the assessee is expected to assess their tax liability, and in case any amount is due, it has to be paid to ensure successful e-filing.

The government levies taxes in multiple forms like TDS, TCS, advance tax, and more. With Self-Assessment tax, you need to assess your income and pay the balance tax (if any) after taking TDS, TCS, and advance tax into account. You cannot file income tax returns until your taxes are paid fully. To put it simply, a Self-Assessment tax is the balance tax that you pay on the total income after deducting the paid TDS and advance tax from your tax liability.

Why Should You Pay Self-Assessment Tax?

Self-Assessment tax is generally paid on income from other sources. There can be instances where you miss out on including a certain income while making the final payment of your advance tax; or, there can be a possibility that TDS was deducted at a lower rate. Salaried individuals often come across such instances.

Let us assume that you are a salaried individual. Like every year, your employer has deducted TDS on salary. However, you earned ₹10,000 on a freelance project and you forgot to inform the same. Hence, tax on this income has not been deducted.

Self-Assessment tax comes in handy during such cases. It helps you compare your total tax liability with the tax already paid to pay the balance. Though no specific date of payment is specified for the Self-Assessment tax, it is advisable to pay it as soon as possible. This will help you escape the penalty on the late tax payment.

What to do if you Choose the Wrong Assessment Year While Paying Tax?

An Assessment year is the one that follows a financial year. The money earned in a financial year is taxed in the consecutive Assessment year. So, the income earned in FY 2021-2022 will be assessed in the AY 2022-2023. However, there can be instances wherein you receive a notice from the Income Tax Department for paying tax in the wrong Assessment year.

Here’s what you must do on receiving such a notice:

The Payment is Made by a Physical Challan

Along with the aforementioned fields, you also need to include details about your challan, i.e. BSR code, challan serial number, and the challan date.
