How Much Tax Do You Still Need to Save in 2026?

Tax planning in India has quietly flipped. For years the question was "how do I save income tax?" In 2026 the sharper question is "do I even need to?" The new tax regime is now the default, it makes income up to ₹12 lakh completely tax-free, and it does this without asking you to lock a single rupee into an insurance policy or tax-saving fund. For a large slice of salaried India, the most efficient move this year is to claim almost nothing and still pay zero.

But that is not the whole story. The old regime is still alive, the classic sections still work inside it, and for people with a home loan and a family to insure, those deductions can be worth more than ever. Here is how to decide, with the current numbers, and the sections that genuinely still matter.

The ₹12 lakh line that changed everything

From FY 2025-26, the new regime gives a Section 87A rebate of up to ₹60,000, which means anyone with taxable income up to ₹12 lakh pays no tax at all. Add the ₹75,000 standard deduction that salaried earners and pensioners get automatically, and a salary of ₹12.75 lakh comes out tax-free without any planning whatsoever.

The slabs above that line, unchanged in Budget 2026 for the coming year, run like this:

• Up to ₹4 lakh: nil
• ₹4–8 lakh: 5%
• ₹8–12 lakh: 10%
• ₹12–16 lakh: 15%
• ₹16–20 lakh: 20%
• ₹20–24 lakh: 25%
• Above ₹24 lakh: 30%

Crucially, the new regime strips away almost every deduction. No 80C, no 80D, no HRA, no home-loan interest on the house you live in. You trade the deductions for lower rates and the big rebate. For most people earning under ₹12.75 lakh, that trade is unbeatable, because no amount of investing can get you below zero.

When the old regime still wins

The old regime keeps the lower exemption limit (₹2.5 lakh) and a smaller ₹50,000 standard deduction, and its rebate under 87A only covers income up to ₹5 lakh. On paper it looks worse. It pulls ahead only when you stack up enough deductions to overcome the gap.

A useful rule of thumb: at higher salaries, the old regime starts beating the new one once your total deductions cross roughly ₹8 lakh a year. That is a big number, and it is realistic only for a specific profile, usually someone paying a home-loan EMI, claiming HRA or interest, maxing 80C, putting money into NPS, and insuring the family. If your deductions add up to ₹2–3 lakh, the new regime almost always wins. If you are nowhere near that, stop optimising and pick the default.

The honest test is to run both calculations on the income-tax portal's built-in comparison before you file. Salaried taxpayers can switch regime every year, so this is not a one-time lock; people with business or professional income get far fewer chances to flip back, so they should choose carefully.

The sections that still work in the old regime

If the maths sends you to the old regime, these are the deductions worth chasing. All figures are annual and apply to the old regime only unless stated.

• Section 80C — up to ₹1.5 lakh. The workhorse. EPF, PPF, ELSS funds, life insurance premiums, principal repayment on a home loan, five-year tax-saving FDs, Sukanya Samriddhi and children's tuition fees all compete for this single ceiling. Most salaried people fill a chunk of it through EPF without trying.
• Section 80CCD(1B) — extra ₹50,000. A voluntary NPS contribution over and above 80C. This is the cheapest way to add headroom if you have already exhausted ₹1.5 lakh.
• Section 80D — ₹25,000, or ₹50,000 for senior citizens. Health insurance premiums for you and your family, plus a separate slab for parents. Insuring senior-citizen parents can take the combined deduction up to ₹1 lakh.
• Section 24(b) — up to ₹2 lakh. Interest on a home loan for a self-occupied property. For a let-out property the rules differ, but this ₹2 lakh cap is the one most homeowners use, and it is often what tips the balance toward the old regime.
• Section 80E. Interest on an education loan, with no upper limit, claimable for up to eight years. Genuinely valuable for families repaying study loans.
• Section 80TTA / 80TTB. Up to ₹10,000 of savings-account interest for most people; senior citizens get a wider ₹50,000 under 80TTB covering deposits too.

A few narrower ones are worth knowing: 80GG gives up to ₹60,000 a year to people who pay rent but get no HRA, 80DD and 80U cover disability-related expenses, and 80G covers donations to approved charities. The EV-loan deduction under 80EEB still exists on paper, but it only applies to loans sanctioned between April 2019 and March 2023, so it is closed to new borrowers.

The one big deduction that survives in the new regime

There is a single significant exception to the "no deductions" rule, and it is worth real money: Section 80CCD(2), your employer's contribution to NPS. This works in both regimes, and from FY 2025-26 the limit is a uniform 14% of basic salary plus DA for all employees, government and private alike.

If your employer offers a corporate NPS facility, restructuring a slice of your salary into this contribution can lower your taxable income even while you stay in the new regime and enjoy the lower rates. For high earners, this is often the most efficient single lever left. The catch is liquidity: the money is locked into your NPS account until retirement, with limited early withdrawals, so treat it as forced long-term saving rather than a quick tax trick.

What to actually do before you file

A short, practical sequence:

1. Add up your real deductions for the year — 80C already paid, health premiums, home-loan interest, NPS, HRA. Be honest; do not count money you have not spent.
2. Run both regimes on the income-tax e-filing portal's comparison tool, or any reliable calculator, using your actual numbers.
3. Pick the cheaper one. If the gap is small and the old regime needs you to buy products you do not want, the new regime's simplicity is worth a little tax.
4. Don't invest only to save tax. A bad ULIP or low-return endowment plan bought in March to claim 80C usually costs more in poor returns than it saves in tax.
5. Keep proof. Premium receipts, loan-interest certificates, NPS statements and rent receipts must be retained even if your employer has already accounted for them.

What changes from here

The direction of travel is clear. The government wants the new regime to be the norm, the slabs and rebate keep getting more generous, and the old regime's web of deductions is being left to wither rather than killed outright. Layered on top is the new Income-tax Act, 2025, which takes effect from 1 April 2026 and renumbers many familiar sections — the relief 80C gives, for instance, sits under a new clause in the rewritten law, though the underlying benefit for the current filing year is unchanged.

For 2026, the smart approach is unsentimental. The old habit of buying insurance and locking money away every March made sense when deductions were the only way to cut your bill. Now, for most middle-class earners, the cleaner win is the new regime's flat, tax-free ₹12.75 lakh. Reserve the old-regime gymnastics for the cases where a home loan and a fully insured family actually push your deductions past the break-even line. Run your own numbers once, and you will know exactly which camp you are in.
