However, there exist a few strategies or standards that often indicate which tax regime might suit which investor category.

Suitable Investor Categories of the New Tax Regime vs Old Tax Regime in India

The choice between the old tax regime and the new tax regime is governed mainly by parameters like salary structure, deductions or exemptions an individual can claim, and investment habits. Although the choice of the tax regime should be based on individual profile analysis, certain broad investor categories can choose particular tax regimes. Discussed below are each of them in detail.

Old Tax Regime

• Heavy investment in tax-saving instruments: If an investor’s portfolio holds assets such as PPF, LIC, ELSS, etc., that offer tax deductions under the Income Tax Act, they might prefer the old regime over the new one.

• HRA Benefits: Salaried employees in metro cities with high rents and HRA benefits often save more in taxes under the old regime.

• Lower to mid-level income with high deductions: The primary benefit of the old tax regime is the deduction under Chapter VI-A. Therefore, if the income is between the lower and mid-level, such that the tax payable is less, the old tax regime can further reduce taxes through deductions.

New Tax Regime

• Don’t have many deductions: If a taxpayer does not have enough eligible deductions to claim and reduce their tax burden, the new tax regime tax slabs are lower than the old regime, providing a reduced tax burden.

• Prefer simpler tax filing: The new regime does not have most exemptions and deductions, making the filing process simple and convenient.

• Beginner Investors: The new regime is the default income tax regime. Furthermore, given the simple and less complex filing process, it is often more convenient for beginners.

• Have a higher salary: If an individual has a high salary and not enough deductions to claim, the new income tax regime becomes a convenient choice. It allows a lower tax burden, compared to the old regime.

Typical Errors to Avoid When Selecting a Tax System

Choosing between the old and the new income tax regimes without optimal analysis often leads to mistakes and unnecessary tax burden. Here are some common mistakes that taxpayers must avoid when choosing an income tax regime.

• Only comparing tax slabs: While the tax slabs are an important point of distinction, they are not enough to make a choice. Investors ought to take the deductions into account. An aggregate view of both tax slabs and deductions can reveal the regime under which a taxpayer can get the lowest tax burden.

• Prioritising tax-saving over profitability: Tax saving is one of the important goals for investing, but it does not supersede profitability. Investors should not concentrate assets only in tax-saving avenues, as it might reduce the gains from their investments.

• Mistakes during filing: Choosing the right regime is the first step. If investors fill in incorrect information in their ITR forms, they might receive an income tax notice or lose the opportunity for tax savings. Therefore, the taxpayers should carefully fill in their tax details in the form.

Bottomline

People should pick between the new and old income tax system by properly analysing their individual portfolio, depending on their investments and salaries. Making an optimal decision here is necessary to reduce the tax burden and get the complete gamut of benefits under the Income Tax Act. Although the new tax regime is the default system and offers lower slab rates, some taxpayers choose the old regime as it offers greater deductions. A comparative understanding of both systems is critical to make an optimal choice.
