This is the benefit given to senior citizens with Old Tax Regime as they enter into their retirement phase.

But as far as New Tax Regime is concerned, there is no such benefit to any age groups apart from reduced tax slab rates for all age groups.

So far we have seen both Old and New Tax Regime. But why do we have 2 regimes and how do we calculate our income tax based on these regimes?

Let’s decode.

Old Tax Regime vs New Tax Regime – which is better?

We have seen tax slab rates for various age groups based on Old Tax Regime and New Tax Regime.

We have the option to choose between them. So we can choose one tax regime out of these two and calculate our tax liability.

Now you will think that since New Tax Regime are having reduced tax slab rates, you will always choose new tax regime to calculate and pay income tax. But that is not the case always.

It depends on your income and investments, to properly analyze your yearly income and investments and select the tax regime with required calculations.

Even though old tax regime is having high slab rates, still you can end up paying less income tax with old tax regime. How?

Remember, that investment options and deductions can be claimed using old tax regime which will help us to save income tax.

So by proper planning of investments and deducting required amount from taxable income, we can easily save lot of income tax using Old Tax Regime.

Which Tax Regime you should choose?

Now the very common question is, which tax regime you should choose so that you have to pay less income tax?

The answer is very simple. You should choose Old Tax regime if your annual income is up to Rs. 15 Lacs and make appropriate investments mentioned here in video to save income tax.

If your income is above Rs. 15 Lacs, then it is wise to choose new tax regime to pay your income tax as no amount of investments will help you to save income tax after Rs. 15 Lacs, due to limits of all investment options mentioned here.

I have also covered some more points in this below video on Old vs New Tax Regime comparison.

Let us now move to income tax calculation examples using our online tax calculator for different age groups.

Income Tax Calculation Example – Age 0 to 59 Years

Let’s say for example, Annual Income (Salary) = Rs. 8 Lacs, Investments = Rs. 0. So calculating Income Tax using our online Tax calculator, we get income tax as:

  • Old Tax Regime = Rs. 65,000
  • New Tax Regime = Rs. 23,400

Below is the screenshot with calculations:

In above calculations, Standard Deduction of Rs. 50,000 and Rs. 75,000 is already considered in both old and new tax regimes respectively and appropriate tax is calculated. No such deduction is considered for new tax regime since these deductions are not allowed in new tax regime.

And seeing the income tax with both tax regime, we should go with New tax regime as we’ll be paying less income tax compared to Old Tax regime, without making any investments.

But you can make investments of Rs. 1,50,000 under Section 80C that includes options like Public Provident Fund, Employee Provident Fund, 5 year Fixed Deposits, Life Insurance premiums, etc. and Rs. 50,000 under Section 80CCD(1B) which includes NPS (National Pension System) under old tax regime and mention same in our calculator’s deductions section, to save income tax.

Let’s calculate income tax for senior citizens.

Income Tax Calculation Example – Age 60 to 79 Years

Let’s take same example as above, Annual Income (Pensioner) = Rs. 8 Lacs, Investments = Rs. 0. So calculating Income Tax using our online Tax calculator, we get income tax as:

  • Old Tax Regime = Rs. 62,400
  • New Tax Regime = Rs. 23,400

Below is the screenshot with calculations:

So over here as well, you will pay less income tax with new tax regime, even though standard deduction of Rs. 50,000 is considered in Old Tax Regime, but there is no other deductions.

Let’s say we invest Rs. 1,50,000 and Rs. 50,000 under Section 80C schemes and Section 80CCD(1B) respectively, so we get following numbers:

  • Old Tax Regime = Rs. 20,800
  • New Tax Regime = Rs. 23,400

Below is the calculations screenshot:

So we can save a lot of income tax with Old tax regime here. Similarly we can make more investments and save more income tax!

Let us see income tax calculation examples for super senior citizens now.

Income Tax Calculation Example – Age above 80 Years

We’ll consider same example of Rs. 8 Lacs annual income as pension, no investments. So calculating income tax with these considerations, we get:

  • Old Tax Regime = Rs. 52,000
  • New Tax Regime = Rs. 23,400

Below is the calculations screenshot:

You should choose new tax regime in this case and pay less income tax.

Let’s say you make investment of Rs. 1,50,000 in section 80C, we get below numbers:

  • Old Tax Regime = Rs. 20,800
  • New Tax Regime = Rs. 23,400

As seen above, you’ll pay less income tax with old tax regime after making investment of Rs. 1.5 Lacs in section 80C.

And in this way you should plan and invest in required investment options in a financial year to reduce your tax liability.

One important point to notice here is while calculating income tax using new tax regime, the income tax is same irrespective of the age group you belong to.

This is because the tax slab rates are same in new tax regime for all age groups.

How to use Tax Rebate u/s 87A?

Tax Rebate u/s 87A is one of the important tax rebate sections that helps us to pay Zero Income Tax.

According to this rebate, if your taxable income is below Rs. 5 Lacs, you get a maximum tax rebate of Rs. 12,500. Now if your income is Rs. 5 Lacs, your tax is Rs. 12,500, which gets cancelled using this tax rebate that is applied automatically, and you end up paying Zero income tax.

This condition is applicable in both old and new tax regime.

But what if your income is above Rs. 5 Lacs? It’s simple, you don’t get this tax rebate, but only according to old tax regime.

With old tax regime, you can make various investments and claim deductions to get your taxable income below Rs. 5 Lacs and use this tax rebate u/s 87A.
