Chapter VI-A of the Income Tax Act: All Deductions (80C to 80U), Limits and New Section Numbers
Quick Summary

The short version

Chapter VI-A of the Income-tax Act, 1961 is the part that holds the deductions from section 80C to 80U — investments, insurance, loans, donations and more. This guide lists each deduction with its limit for FY 2025-26, shows which ones survive in the new tax r…

What is Chapter VI-A?

Chapter VI-A of the Income-tax Act, 1961 contains the deductions you subtract from your gross total income to arrive at taxable income: sections 80C to 80U. "Chapter VI-A deductions" on a Form 16 or ITR means these.

Two things have changed how they work:

  • The new tax regime, the default since FY 2023-24, allows almost none of them.
  • The Income-tax Act, 2025 applies from 1 April 2026 and moves these deductions to a new chapter with new section numbers. The limits are carried over.

Returns for FY 2025-26 (filed in 2026) still use the old 80C-style sections.

Old section to new section (Income-tax Act, 2025)

Income-tax Act, 1961Income-tax Act, 2025
80CSection 123, read with Schedule XV
80CCD (NPS)Section 124
80CCH (Agniveer)Section 125
80D (health insurance)Section 126
80DD (dependant with disability)Section 127
80DDB (specified diseases)Section 128
80E (education loan)Section 129
80G (donations)Section 133

The ₹1.5 lakh savings limit carries over unchanged in section 123. From Tax Year 2026-27, payroll declarations and Form 130 (the new Form 16) use the new numbers. People will keep saying "80C" for years, and both refer to the same deduction.

Should you claim these at all? Old vs new regime

Under the new regime, income up to ₹12 lakh is tax-free after the rebate (₹12.75 lakh for salaried people, with the ₹75,000 standard deduction). Most Chapter VI-A deductions aren't allowed. Under the old regime you get the deductions but higher tax rates.

As a rough guide, the old regime starts to pay off only when your deductions are large. That means a full ₹1.5 lakh under 80C, plus health insurance, HRA and home-loan interest together. Run both with our salary calculator before choosing.

How to claim them

  • Salaried: declare investments to your employer early in the year so TDS is lower, and submit proofs before the year-end cut-off. Anything missed can still be claimed in your ITR if you're filing under the old regime.
  • Everyone: keep the receipts and certificates, and make sure the deduction amounts in your ITR match them. Mismatches with Form 16 are a common trigger for notices.

TaxQue's income tax return filing service compares both regimes and claims every deduction you're entitled to.
