In India, the government introduced a new optional tax regime from the financial year 2020-21 onwards to simplify the tax structure and lower tax rates. With the new provisions introduced in the Union Budget 2023, the new tax regime has become the default one, replacing the old tax regime that existed before.
However, taxpayers still have the choice to switch to the old regime if they find it more beneficial based on their income level and deductions/exemptions available. Let's understand the difference between old and new tax regimes with respect to tax rates, deductions available, and how they can help you in tax planning.

Tax rates under old vs new regime

Mutual funds in India are an investment avenue that pool money from multiple investors to invest in a diversified portfolio of stocks, bonds, or other securities. These funds are managed by professional fund managers who make investment decisions to achieve the fund's objectives. Investors purchase units in the mutual fund, owning a portion of its holdings proportional to their investment.

Under the old tax regime, there were 3 tax slabs with rates ranging from 5% to 30% excluding cess and surcharges. Taxpayers were eligible for a host of around 70 exemptions and deductions that could significantly reduce their tax outgo.

On the other hand, the new tax regime offers significantly lower tax rates within 5 slabs ranging from 5% to 30%. However, taxpayers opting for the new regime will not be eligible for most common deductions like HRA, LTA, 80C, home loan interest, etc.

To illustrate – for an income between Rs. 9-12 lakh, the tax rate is 30% under the old regime but only 15% under the new. Similarly, income above Rs. 15 lakh attracts a maximum rate of 30% in the old regime versus 15% in the new regime. Below is a tabular comparison of new tax regime vs old regime.

Deductions allowed

Some key deductions like family pension deduction, and employer's NPS contribution are now available in both regimes. However, the old regime allows nearly 70 exemptions and deductions like HRA, LTA, Section 80C investments up to Rs. 1.5 lakh, home loan interest, medical insurance, tuition fees, children education allowance, leave encashment etc. These exemptions are not permitted under the new regime.

Impact on taxpayers across slabs

Income up to Rs. 15 lakh annually

It is estimated that the new tax regime could be more tax efficient for individuals with an annual income of up to Rs. 15 lakh. In this income bracket, the lower tax rates under the new regime along with limited deductions make it advantageous compared to the old tax regime. The standard deduction available in both regimes and other deductions like NPS contribute further to reducing the tax outgo.

Income between Rs. 15-20 lakh annually

However, for taxpayers with an income in the Rs. 15-20 lakh slab, the choice between old and new regime will depend on the case. Individuals will need to evaluate the exact deductions available to them like HRA, home loan interest, etc. and compare the tax savings under both regimes to determine which provides better savings based on their situation. It may suit some but not all individuals in this income bracket.

Income above Rs. 20 lakh annually

For those earning an annual income exceeding Rs. 20 lakh, the old tax regime is likely to be more tax efficient. At higher income levels, the substantial deductions and exemptions available exclusively in the old regime can significantly offset tax payments. The savings may outweigh the benefits of lower tax rates of the new tax regime for individuals with income above Rs. 20 lakh.

Other budget provisions

The Budget 2023 introduced some changes to make new regime more attractive:

  • Increased basic exemption limit to Rs. 3 lakh from Rs. 2.5 lakh in old regime
  • Total tax rebate raised to Rs. 7 lakh from Rs. 5 lakh earlier
  • Simplified and reduced surcharge rates for high income individuals
  • Leave encashment exemption limit increased 8 times to Rs. 25 lakh

Summing up

Whilst the new tax regime offers simplicity with lower rates and fewer deductions, the old regime allows optimising tax outgo substantially through various exemptions for eligible taxpayers. Individuals must evaluate their tax liabilities after claiming all deductions/exemptions in both regimes to choose what fits them best. Overall, the new regime could be relatively advantageous for most individual taxpayers with annual income up to Rs. 15 lakh.
