For taxpayers who choose the old tax regime, Section 80C is the largest single deduction available — up to ₹1.5 lakh of qualifying investments and expenses reduce your taxable income, saving up to ₹46,800 in tax at the 30% slab (or ₹31,200 at 20%). It is also the most-Googled tax topic in India each filing season for a reason: a long list of eligible items, several proof requirements, and recurring confusion about what counts and what doesn't. Here is the complete 80C map for AY 2026-27.

Investment-based deductions
Insurance-based deductions
Home-related deductions
Education-related deductions
Pension-related deductions

The following are not 80C — they sit under other sections:
A clean 80C claim survives scrutiny when these are at hand:
If you are at zero 80C and have ₹1.5 lakh of capacity (and want to genuinely save the tax under the old regime), the practical order is:
This isn't investment advice — it's the 80C optimisation order. Whether 80C investments are right for your portfolio depends on your goals.
