Under TDS, when an Indian entity makes certain payments (salary, professional fees, rent, contractor payments, commission, etc.), they deduct a percentage as income tax and pay it to the government on behalf of the recipient. The recipient claims this as credit against their final tax liability via Form 26AS.
Common TDS rates for SMBs: salary (slab-based), professional fees u/s 194J (10%), contractor payments u/s 194C (1-2%), rent above ₹50K/month u/s 194I (10% on building, 2% on equipment), commission u/s 194H (5%), payments to e-commerce sellers u/s 194-O (1%).
TDS returns are filed quarterly (TDS-1, TDS-2 for non-salary; 24Q, 26Q, 27EQ depending on type). Form 16 / 16A is the certificate issued to the deductee.
