I run a small consultancy firm (partnership with my mother) from my residence address. My firm is not registered, but I do have a separate PAN for it. I do not have any salaried employees. I get work done by freelancers and vendors and pay them against invoice. My annual revenues are just about Rs 5-6 lakhs. I am aware that I would need to register for service tax once I touch Rs 9 lakhs. But I am confused about my obligation to get a TAN and deduct TDS for all vendor/freelancer payments. Are there any minimum thresholds for withholding TDS? Right now I pay 100% of invoice amounts. Please advise.
