Partly. s.192(1) requires deduction on the 'estimated income of the assessee under this head', so the employer's duty is to estimate honestly and fairly, not to arrive at the figure a completed assessment would produce. But good faith answers the penalty under s.271C far better than it answers the demand: the Supreme Court in Eli Lilly directed recovery of the shortfall under s.201(1) with interest under s.201(1A) while holding that no penalty should be levied because the issue was nascent and the employers had acted bona fide.
The obligation in s.192(1) of the Income-tax Act, 1961 is expressed as an estimate. Tax is to be deducted 'on the amount payable at the average of income-tax computed on the basis of the rates in force for the financial year in which the payment is made, on the estimated income of the assessee under this head for that financial year'. The employer deducts month by month against a forecast of what the employee's salary income for the year will be. That is a different exercise from assessment, and the statute says so.
Two consequences follow from the word 'estimated'. The first is that an estimate which turns out to be wrong is not by that fact alone a default — otherwise every mid-year change in an employee's declarations would create a s.201 liability. The second is that the estimate must still be a real one: s.192(2B) lets the employee report other income and tax deducted elsewhere, but its proviso stops that from 'reducing the tax deductible from the income under the head Salaries below the amount' otherwise deductible, so the employer cannot use employee declarations to deduct less than the salary itself warrants.
The Supreme Court's decision in CIT v. Eli Lilly & Co. (India) P. Ltd. is the decision to work from. The reports of it record the Court treating the s.192(1) exercise as an estimation of income akin to computation, and then separating the three consequences of a shortfall. On tax, the assessing officer was to proceed under s.201(1) to recover the shortfall. On interest, the digest records the holding as: 'Levy of interest u/s 201 (1A) is mandatory and has to be calculated from the date of default to the date of payment either by the assessee or the payee-employee.' That sentence is the digest's headnote and not language taken from the judgment. On penalty, the Court held that no proceedings under s.271C were to be taken because the issue involved was a nascent one and the assessees had acted bona fide — s.271C being subject to the 'good and sufficient reason' test.
That is the shape of the defence and its limits. Bona fides is the statutory test for penalty and it works there. It is not the statutory test for s.201(1), where the question is whether tax that should have been deducted was not. What good faith does at the s.201(1) stage is more indirect: it goes to whether the estimate was an estimate at all, made on the material the employer had.
The two decisions this library already holds show where that argument fails. In State Bank of India v. CIT the Supreme Court held that because the complete travel particulars were before the bank when it settled the leave travel concession bills, the bank could not say it was unaware of the foreign legs; having had the material and treated the whole reimbursement as exempt, its estimate was not honest. In State Bank of India v. ACIT (TDS) the Karnataka High Court rejected a bona fide belief that had no legal foundation, noting particularly that the bank had never approached the tax authorities for clarification before deciding not to deduct. The pattern in both is the same: the plea fails where the employer held the facts that would have produced the right answer, or took a view of the law without asking. Conversely, in Government Polytechnic Education Society v. ITO (TDS) the Tribunal found there was nothing to deduct at all because each individual's monthly remuneration was below the taxable limit, so the estimate produced a nil figure and no s.201 default could arise.
Where the dispute is characterisation — the officer says your consultants are employees and you should have deducted under s.192 rather than s.194J — the estimate argument is at its most useful in a particular way. If the engagement was genuinely treated as professional, no salary estimate was ever made, and the question is whether the employer's view of the relationship was a tenable one. That is a s.271C argument on all fours with Eli Lilly, and a poorer s.201(1) argument, which is why the more productive line on the demand itself is usually that the payees have already paid their tax — the first proviso to s.201(1) — rather than that the employer meant well.
On the Income-tax Act, 2025: this library records s.398 as the successor to s.201; I did not locate the successor to s.192 from an official source.
Employers reach for good faith as a single answer to a composite notice, and it is not one. Separating the tax, the interest and the penalty is what turns an unarguable position into a partly winnable one — and the penalty limb, which is where the plea actually works, is often the largest number on the notice after the tax. It also tells you what evidence to build: what material the payroll function held when it made the estimate, and what view of the law it took and why.
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?
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?
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?
My Indian payer did not deduct tax at source and paid me gross. The Assessing Officer says I should have paid advance tax and has charged s.234B interest. Which years can he do that for?
You pay a foreign supplier for software. Is that royalty, and must you deduct TDS?
