Shahi & Co. — Our Understanding
This section falls under Chapter VIII which provides deductions from gross total income — these reduce your taxable income and directly lower your tax liability.
Practical Note: Unlike exemptions (Chapter III), deductions require active claiming in the ITR. Ensure proper documentation — payment proofs, investment certificates, employer certificates — is maintained for every deduction claimed.
