Honestly, your CA uncle is not wrong but he might be working off old assumptions. Let me break this down for your specific situation because the 2026 budget changes actually tilted things quite a bit.
In the new regime after budget 2026, the ₹0 tax slab now goes up to ₹12 lakh (with rebate under 87A effectively making it zero). Above that the slabs are more generous too. And the standard deduction in new regime is ₹75,000 now. So for a lot of people with CTCs in the ₹12-20L range, new regime suddenly looks very attractive.
But here's the thing — your situation has some real deductions working in your favour for old regime. Let me roughly estimate:
Your gross taxable income is around ₹18L. In old regime you can claim:
- Standard deduction: ₹50,000
- 80C (PPF + ELSS): ₹1,50,000
- Home loan interest under Section 24b: ₹2,00,000 (max allowed, you said ₹22k/month interest = ₹2.64L but capped at ₹2L)
- 80D health insurance: ₹12,000
- 80CCD(1B) NPS if you're investing: up to ₹50,000 extra
So in old regime your taxable income drops to roughly ₹18L minus ₹4.12L = around ₹13.88L. Tax on that comes to roughly ₹2.1-2.2 lakh.
In new regime: ₹18L minus ₹75k standard deduction = ₹17.25L taxable. Tax on that under new 2026 slabs comes to approximately ₹2.3-2.5 lakh.
Old regime wins for you. Barely, but it wins. And if you start NPS through your employer's 80CCD(2) route — which is available in new regime too actually — that gap widens.
One thing most people get wrong: they forget that home loan principal repayment under 80C is already counted in their ₹1.5L limit. Don't double count it.
My clear recommendation: stay in old regime this year given your home loan interest and 80C investments. But run the actual numbers on ClearTax or the Income Tax portal's calculator with your exact figures before submitting. Don't just go by gut feel or what your colleague said.
