The 80C field disappears because ITR-1 defaults to the NEW tax regime for AY 2026-27, where Section 80C deductions are not available.
To unlock 80C:
- In the ITR-1 online portal, find the tax regime selection (first section of the return)
- Change it from New Regime to Old Regime
- Schedule VI-A (80C, 80D, 80E etc.) will now become fully editable
Note for AY 2026-27: New regime is now the DEFAULT. You must actively switch to old regime to see those deduction fields.
Whether you SHOULD switch depends on your numbers:
- New regime: lower slab rates, zero tax up to Rs 12 lakh, no deductions needed
- Old regime: higher slabs, but 80C (Rs 1.5 lakh), 80D, HRA, home loan interest all allowed
The portal lets you run a quick comparison when you switch - check estimated tax under both before deciding. Most salaried individuals with Rs 1.5 lakh+ in 80C investments and HRA still benefit from old regime above Rs 15-17 lakh income.
