It’s January 2026. If you are working in Hinjewadi Phase 1 or Magarpatta City, your HR has probably just sent that dreaded email: "Please submit your Investment Proofs by Jan 20th."
As a CMA student, I spent the last weekend analyzing the numbers. The government has aggressively pushed the New Tax Regime this year with a massive sweet spot: Zero Tax for income up to ₹12 Lakhs (after rebate).
But is it actually better for you? Or should you stick to the Old Regime with your HRA and 80C?
Below is the 2026 Tax Calculator Guide to help you decide in 5 minutes.
The 2026 Tax Slabs (FY 2025-26 | AY 2026-27)
Before you calculate, you need the raw numbers. The Budget 2025 introduced significant relief in the New Regime, making it the default choice for most freshers.
| Income Slab | New Regime Rate (2026) | Old Regime Rate |
| ₹0 – ₹2.5 Lakh | NIL | NIL |
| ₹2.5 Lakh – ₹4 Lakh | NIL | 5% |
| ₹4 Lakh – ₹5 Lakh | 5% | 5% |
| ₹5 Lakh – ₹8 Lakh | 5% | 20% |
| ₹8 Lakh – ₹10 Lakh | 10% | 20% |
| ₹10 Lakh – ₹12 Lakh | 10% | 30% |
| ₹12 Lakh – ₹16 Lakh | 15% | 30% |
| Above ₹24 Lakh | 30% | 30% |
NJ’s Key Note: In the New Regime, you now get a Standard Deduction of ₹75,000.
This means if your salary is ₹12.75 Lakhs, your taxable income becomes ₹12 Lakhs, and you pay ZERO TAX due to the Section 87A rebate.
The "Mental Calculator" (Do This First)
You don't always need complex software. Use this simple "NJ Rule of Thumb" to check if the Old Regime is worth your time.
The "Breakeven" Formula: You should only choose the Old Regime if your total deductions (80C + 80D + HRA + Home Loan) are greater than ₹4.25 Lakhs.
Step 1: Add up your deductions.
80C: ₹1.5 Lakh (Max)
80D (Health): ₹25,000
Standard Deduction: ₹50,000
HRA: (Actual Rent - 10% of Basic)
Step 2: Check the total.
If Total > ₹4.25 Lakhs → Go Old Regime.
If Total < ₹4.25 Lakhs → Go New Regime.
For most of us living in PGs like Stanza Living or renting flats in Wakad, our HRA isn't high enough to beat the New Regime's low rates.

Calculate It in 2 Minutes (Official Tool)
While you can create complex Excel sheets, the government has released an official calculator that is 100% accurate.
Important Note: Before you enter your numbers there, keep your "NJ Break-Even Number" in mind:
If your total deductions (HRA + 80C + 80D) are less than ₹4.25 Lakhs, simply choose the New Regime. You don't even need to calculate further.
Conclusion: My Advice for 2026
If you are a student or fresher with a salary under ₹12 Lakhs, don't blindly invest in LIC or PPF just to save tax. The New Regime makes your income tax-free automatically.
Instead, use that money to build capital. Invest in skills (like the CMA US) or high-growth assets. As per my NJ Trading Rules, capital preservation is key, but liquidity is king. The New Regime gives you more cash in hand today.
