₹20 Lakh Salary: New Tax Regime Under Section 115BAC Often Beats Old Regime Deductions

(INDIA) — Salaried Indians earning ₹20 lakh are increasingly choosing between the old tax regime and the new tax regime on the basis of one question: whether their deductions are large enough to outweigh the lower slab rates now available under Section 115BAC. The new tax regime is the default option for FY 2025-26 / AY 2026-27, while taxpayers who want the old regime must actively opt for it when they file their return.

That choice has become more consequential for people whose finances do not fit a standard salary template. Rent in large cities, home loans, employer retirement benefits, health insurance and the tax treatment of India-sourced income can all shift the outcome. The difference is not limited to residents with straightforward payroll income. It also affects NRIs with Indian salary income, returning residents and workers whose earnings span more than one country.

Under the current framework, the new tax regime offers lower slab rates but removes most deductions and exemptions that salaried taxpayers long used to cut their liability. The old regime still allows claims tied to housing rent allowance, Section 80C investments, medical insurance, home loan interest and National Pension System contributions, among others. At the same salary level, the better option depends less on the headline slab and more on what sits inside the pay structure.

For individuals below 60 years, the new-regime slab structure for AY 2026-27 starts with Nil tax up to ₹4 lakh. Income from ₹4 lakh to ₹8 lakh is taxed at 5%, ₹8 lakh to ₹12 lakh at 10%, ₹12 lakh to ₹16 lakh at 15%, ₹16 lakh to ₹20 lakh at 20%, ₹20 lakh to ₹24 lakh at 25%, and income above ₹24 lakh at 30%.

Those slabs explain why the new tax regime often comes out ahead even for taxpayers who still have some deductions under the old system. A worked comparison for a salaried person earning ₹20 lakh found tax liability of about ₹1.87 lakh under the old regime and about ₹1.63 lakh under the new regime. In that example, the new regime reduced tax by about ₹24,000.

That comparison did not show that the old regime has lost all value. It showed something narrower and more useful. At a salary of ₹20 lakh, the old regime usually needs a heavy deduction profile to beat the new one. Taxpayers with modest claims, even after accounting for standard salary deductions, often still land lower under the new structure.

The old regime remains competitive where deductions are large and recurring. Housing rent allowance can materially reduce taxable income for salaried employees who pay high rent, especially in metro cities. Section 80C claims can include EPF, PPF, ELSS, life insurance, tuition fees and home loan principal. Section 80D covers health insurance premiums, while Section 24(b) applies to home loan interest on a self-occupied house. NPS contributions and leave travel allowance can add further relief if the conditions are met.

High rent and large home loan interest are often the two elements that most sharply change the math. An employee in a metro city with substantial HRA exemption may find the old tax regime closer to the new tax regime than the slab tables alone suggest. A housing loan can tilt the comparison further if the taxpayer also claims home loan interest along with 80C, 80D and NPS deductions.

At the same time, the break-even threshold is demanding. For someone earning ₹20 lakh a year, the old regime generally becomes attractive only when total deductions and exemptions reach around ₹7.5 lakh to ₹8.5 lakh or more. That is well above the level reached by many salaried taxpayers who rely mainly on basic 80C investments and the standard deduction. In those cases, the new tax regime usually remains ahead.

That threshold also helps explain why younger salaried workers often lean toward the new structure. A taxpayer with no home loan, low or no rent exemption and limited investment under 80C usually does not generate enough deductions to offset the lower slab rates under Section 115BAC. By contrast, a person with high rent in a metro city, large home loan interest and employer NPS contributions has a more credible case for running the old-regime calculation seriously before filing.

Cross-border workers face an added layer. The regime choice applies to Indian taxable income, not automatically to all income earned worldwide. India tax obligations can still arise from salary earned in India or credited in India, Indian rental income, capital gains from Indian assets and some interest income from Indian bank accounts, depending on the account type and residential status. ESOPs or RSUs linked to Indian employment may require more detailed tax allocation.

Residential status remains central for NRIs, overseas Indians and returning residents. Foreign income is not pulled into the Indian tax base simply because a taxpayer chooses the old tax regime or the new tax regime. The treatment depends on residential status, the source of income, treaty relief and the applicable tax year. That means the regime decision is one tax calculation layered on top of a broader determination about what income India can tax in the first place.

Students returning from abroad, new graduates taking up Indian jobs and workers re-entering the Indian tax system after time overseas sit in a similar position. The old regime can look attractive because it offers more exemptions on paper, but that does not mean it produces a lower bill in practice. If there is no home loan, rent relief is limited and 80C investments are modest, the new regime may still offer the lower outgo. Once rent, housing interest and employer NPS contributions rise, the comparison can change.

Before filing, salaried taxpayers need a side-by-side calculation built from their actual `Form 16` and salary structure. Gross salary, standard deduction, HRA exemption, 80C, 80D, NPS, home loan interest, other allowances, taxable income after exemptions and the final tax liability under both systems, including cess, all need to be tested using the official slabs for AY 2026-27. For most people around ₹20 lakh, the new tax regime is simpler and often cheaper. The old tax regime still matters, but mostly where deductions are strong enough to cross the roughly ₹7.5 lakh to ₹8.5 lakh range.
