FAQ
Which financial year does this calculator use?
It is configured for FY 2025-26, also known as assessment year AY 2026-27.
Why are my deductions disabled in the new tax regime?
Most common deductions available in the old regime are not available in the new regime, so this calculator ignores them when the new regime is selected.
Does this calculator include surcharge?
No. The tool focuses on common slab, rebate, marginal relief, and cess estimates. High-income surcharge cases should be checked separately.
Is this a filing-ready tax computation?
No. It is a quick planning estimate. Use official forms or consult a qualified tax professional before filing your return.
