Who deducts TDS under Section 194J?
Companies, firms, government bodies, and individuals or HUFs whose own business turnover requires a tax audit. If your client is an ordinary individual hiring you for personal work, they generally don't deduct TDS at all.
Is TDS calculated on the GST amount too?
No — when GST is shown separately on your invoice, TDS is deducted only on the fee amount, excluding GST. That's why this calculator asks for fees excluding GST.
How do I get TDS back if it's more than my tax?
Many freelancers under Section 44ADA owe less tax than the flat 10% their clients deduct. Any excess is refunded when you file your income tax return — so filing on time matters even if you think you owe nothing. Check that every client's deduction appears in your Form 26AS before filing.
