New Tax Regime vs Old: Which One Should You Pick in FY 2026-27?
Every April, the same question: new regime or old? Your colleague says old is better. Your CA uncle says new. HR sends a form and you pick whichever you picked last year without thinking.
That’s how most salaried Indians handle their biggest annual tax decision. By not deciding at all.
The previous article covered how income tax works, what TDS is, and what your payslip means. This one answers the one question everyone asks: which regime saves you more money?
The key difference
| New Regime (2026) | Old Regime | |
|---|---|---|
| Tax slabs | Lower rates, ₹4L increments | Higher rates |
| Deductions (Sec 80C, 80D, HRA, etc.) | Not allowed (mostly) | Allowed |
| Standard deduction | ₹75,000 | ₹50,000 |
| Section 87A rebate | Taxable income up to ₹12L = zero tax (as of Budget 2025) | Up to ₹5L only |
| Default | Yes (you have to opt out to use old) | No |
The new regime gives you lower tax rates but takes away most deductions. The old regime has higher rates but lets you reduce your taxable income through deductions. The question is: do your deductions save you more than the lower rates would?
Important: The new regime is the default not just because it’s cheaper for most people, but because it’s simpler. No tracking deductions, no collecting proofs, no last-minute Sec 80C panic. If you do nothing, HR will deduct tax based on new regime slabs. If you want the old regime, you must proactively submit a declaration to HR every year.
Slabs and rebate limits are based on the Union Budget 2025 (FY 2025-26 / AY 2026-27). These can change in future budgets. Always verify the latest numbers before filing.
New regime slabs for FY 2026-27
| Income slab | Tax rate |
|---|---|
| Up to ₹4 lakh | Nil |
| ₹4L - ₹8L | 5% |
| ₹8L - ₹12L | 10% |
| ₹12L - ₹16L | 15% |
| ₹16L - ₹20L | 20% |
| ₹20L - ₹24L | 25% |
| Above ₹24L | 30% |
As of Budget 2025: if your taxable income after the ₹75,000 standard deduction is ₹12 lakh or less, you pay zero tax under the Section 87A rebate. That covers gross salaries up to roughly ₹12.75 lakh. This threshold has changed across budgets, so verify for the year you’re filing.
When the new regime wins
If your gross salary is under ₹12.75 lakh (as of current rules), stop reading. Pick the new regime. Your tax is ₹0.
For everyone else: if you don’t have a home loan, don’t claim HRA, and have no major investments beyond EPF, the new regime is almost always cheaper. The lower slabs and the wider standard deduction do the work for you. No paperwork, no investment proofs, no January scramble.
This is the reality for most people in their 20s and early 30s: renting through company accommodation or living with parents, no home loan yet, EPF is the only Sec 80C contribution. The new regime is built for you.
When the old regime wins
The old regime saves you more tax only if you have enough deductions. The common ones:
| Deduction | Section | Max limit |
|---|---|---|
| PPF, ELSS, EPF, life insurance | Sec 80C | ₹1,50,000 |
| Health insurance premium | Sec 80D | ₹25,000 (₹50,000 for senior citizens) |
| Home loan interest | 24(b) | ₹2,00,000 |
| HRA | 10(13A) | Depends on rent and salary |
| NPS employee contribution | Sec 80CCD(1B) | ₹50,000 |
If your total deductions exceed ₹5 lakh, the old regime may start making sense, depending on your salary level and how your salary is structured (basic vs allowances, HRA city, etc.). Below that threshold, the new regime’s lower slabs almost always win.
Quick comparison at different salary levels
Salary: ₹10 lakh (no deductions beyond EPF)
| New Regime | Old Regime | |
|---|---|---|
| Taxable income | ₹9,25,000 | ₹7,00,000 |
| Tax payable | ₹0 (Section 87A rebate) | ₹52,500 |
| Winner | New Regime |
Since ₹9.25 lakh is under the ₹12 lakh rebate limit, the new regime gives you zero tax. No contest.
Salary: ₹15 lakh (₹4 lakh total deductions)
| New Regime | Old Regime | |
|---|---|---|
| Taxable income | ₹14,25,000 | ₹10,50,000 |
| Tax payable | ₹97,500 | ₹1,32,600 |
| Winner | New Regime |
Even with ₹4 lakh in deductions (80C + 80D + HRA), the new regime saves you about ₹35,000. The 2026 slabs have pushed the break-even much higher than before.
Salary: ₹20 lakh (₹5 lakh total deductions including HRA + home loan)
| New Regime | Old Regime | |
|---|---|---|
| Taxable income | ₹19,25,000 | ₹14,50,000 |
| Tax payable | ₹1,92,400 | ₹2,57,400 |
| Winner | New Regime |
Even at ₹20 lakh with ₹5 lakh in deductions, the new regime saves you about ₹65,000. The old regime needs significantly higher deductions to compete now.
Note: These are approximate calculations to show the direction, not exact statutory outputs. Actual tax depends on your specific salary structure, HRA city, cess, surcharge (for higher incomes), and exact deductions. Run your own numbers before deciding.
The simple rule
The 1-line version: If you don’t actively optimise taxes through a home loan + full Sec 80C + HRA, the new regime is almost always better.
The longer version:
- Is your gross salary under ₹12.75 lakh? Pick new regime. Tax is zero (under current rules)
- List all your deductions (Sec 80C, 80D, HRA, home loan interest, NPS)
- Add them up
- If total deductions > ₹5 lakh and salary > ₹15 lakh, run the numbers for both regimes
- Otherwise, new regime
You can switch every year. This is not a permanent choice. Salaried employees can pick the regime that works best for each financial year. Got a home loan this year? Maybe old regime. Sold the house next year? Switch to new. Re-evaluate every April.
Don’t invest just to save tax
Don’t mix up investing with tax saving. If you invest in good products like NPS, health insurance, or a home loan, the tax benefit is a bonus. That’s fine.
The problem is when someone buys a bad LIC endowment or ULIP just to fill up ₹1.5 lakh under Sec 80C. These policies give poor returns and barely any real insurance coverage. You save ₹30,000-45,000 in tax but lock up ₹1.5 lakh for 15-20 years in a product earning 4-5%. That’s a bad trade.
If the new regime is only slightly more expensive but saves you from a bad investment, take the new regime.
