I deducted TDS but under the wrong section, so it was less than it should have been. Is that as bad as not deducting?
Legally both are failures to deduct, and both make you an assessee in default under section 201(1) — but only to the extent of the shortfall in a short-deduction case. The practical difference is size: short deduction usually means a small tax demand plus 1% interest, while non-deduction exposes the whole payment to 30% disallowance under section 40(a)(ia).
Section 201(1) does not distinguish. It says that a person required to deduct who "does not deduct, or does not pay, or after so deducting fails to pay" is deemed to be an assessee in default. Deducting 2% where 10% was due is a failure to deduct the balance 8%. The department computes the demand on the shortfall alone, so a short-deduction order is normally much smaller than a non-deduction order on the same invoice.
Interest is where the two diverge in rate. Section 201(1A) charges 1% per month or part of a month where tax was not deducted, running from the date it was deductible to the date it is actually deducted; and 1.5% per month or part where tax was deducted but not paid, running from the date of deduction to the date of payment. Short deduction sits in the 1% limb for the shortfall. A deductor who deducted correctly but paid late sits in the 1.5% limb — and that is the more expensive default even though nothing was under-deducted.
The disallowance consequence is not symmetrical either, and this is where the argument actually happens. Section 40(a)(ia) disallows 30% of a sum payable to a resident "on which tax is deductible at source under Chapter XVII-B" if the tax has not been deducted or, after deduction, has not been paid by the section 139(1) due date. The Kerala High Court in CIT v. PVS Memorial Hospital Ltd. held that deducting under the wrong provision — 194C in place of 194J — does not satisfy Chapter XVII-B, so the shortfall attracts disallowance. Other benches have taken the view that a deduction made bona fide under one section is a deduction, and that section 40(a)(ia) is aimed at non-deduction rather than inadequate deduction. The position is not uniform.
Penalty tracks the tax, not the label. Section 271C imposes a penalty equal to the tax not deducted or not paid; section 271CA does the same for TCS. Section 273B saves the deductor who proves reasonable cause. A genuine, documented classification dispute is the natural reasonable-cause case; ignoring a vendor entirely is not.
Both defaults are curable in the same way. If the resident payee has filed a return, taken the sum into account in computing income and paid the tax due on the income declared, the first proviso to section 201(1) takes you out of default on production of an accountant's certificate — and that proviso applies to short deduction as much as to non-deduction. Interest under section 201(1A) still runs, but only up to the date the payee furnished his return.
Under the Income-tax Act, 2025 the same structure appears in section 398, which deems a person who "does not deduct or pay, or does not collect or pay" to be an assessee in default, carries the same 1% and 1.5% interest limbs and the same accountant's-certificate exception, and restricts penalty to failures found to be without good and sufficient reasons. The department's own TDS FAQ states the disallowance consequence for the new Act as 30% of resident payments and 100% of non-resident payments.
Short-deduction intimations from CPC-TDS are the highest-volume TDS notice there is, and most of them are classification disputes rather than evasion. Knowing that the exposure is the shortfall plus 1% interest — not the whole payment — stops clients from over-settling. Conversely, treating a wholly missed vendor as a minor issue understates it badly, because 30% of the expense goes with it.
We sell prepaid SIMs and vouchers to distributors below list price. Is that margin commission under 194H?
I have paid the short-deducted tax and the interest to close the matter — can the department still levy penalty under section 271C?
We pay interconnect and port charges to another telecom operator — is that fees for technical services on which we must deduct tax under section 194J?
I deducted TDS during the year but paid it after 31 March, though before I filed my return — can the expense still be disallowed under section 40(a)(ia)?
The TDS officer says I under-deducted under s.192. If my estimate was made honestly, does that answer the demand, the interest and the penalty?
My employees exercised stock options but the shares are locked in and non-transferable. Was I supposed to deduct tax on the market value less what they paid?
We paid stock exchange transaction charges without TDS. Are those fees for technical services under 194J?
As an employer, must I collect bills and tickets from employees before treating leave travel concession or conveyance allowance as exempt while deducting tax under section 192?
