Individual and HUF incl their Proprietorship not having Audit U/s 44AB in the preceding year do not have to deduct TDS. In the current year, they start deducting only after they cross the turnover / receipts for 44AB Audit. This is for Section 194A, 194C, 194H, 194I, 194J. However even if audited they are not to deduct TDS for payments exclusively for personal expenses u/s 194C and 194J.
Whether audited or not, individuals and HUF have to deduct TDS u/s 192 for salaries and 195 for payments to non-residents. Certain personal foreign exchange remittances are excluded from TDS u/s 195 as specified by RBI and as provided in relevant clauses of DTAAs with other contracting states.
I suggest you keep a printout of the above 2 paragraphs handy so that you do not go wrong.
