Consequences of Failure to Deduct or Pay TDS and TCS

Understand Defaults, Interest, Penalty and Section 477 Failure

Key rules to remember

Interest on late deduction or collection (section 398(3)(a)(i))

Tax × 1% × months (or part of a month) from the date tax was deductible or collectible to the date it is deducted or collected

Simple interest. Any part of a month counts as a full month.

Interest on late payment (section 398(3)(a)(ii))

Tax × 1.5% × months (or part of a month) from the date of deduction or collection to the date of actual payment

Simple interest. Interest must be paid before furnishing the statement.

Where payee has filed return and paid tax (section 398(3)(c))

1% interest runs only from the date tax was deductible or collectible to the date the payee furnishes the return of income

Applies when the person is not deemed an assessee in default under section 398(2), which needs the accountant's certificate.

Time limit for default order (section 398(5))

Later of: 6 years from the end of the tax year in which tax was deductible or collectible, or 2 years from the end of the tax year in which a correction statement is delivered

Section 286(1) and 286(3) apply to the limit.

Penalty for non-deduction or non-payment (section 448)

Penalty = tax not deducted or not paid

The Assessing Officer 'may' impose it. Applies to failures under Chapter XIX-B and the specified notes in section 393.

Penalty for statement default (section 461)

₹10,000 minimum to ₹1,00,000 maximum

For late delivery or incorrect information. No penalty for delay if tax with fee and interest is paid and the statement is filed within one month of the due time.

Prosecution for TCS not paid (section 477(1))

Tax above ₹50 lakh: imprisonment up to 2 years, or fine, or both. Tax above ₹10 lakh up to ₹50 lakh: imprisonment up to 6 months, or fine, or both. Any other case: fine

Simple imprisonment. No prosecution if tax is paid on or before the time for filing the statement under section 397(3)(b) (section 477(2)).

How to solve Defaults, Interest, Penalty and Section 477 Failure questions

1. 1Identify the failure: not deducted or collected, deducted but not paid, late statement, or incorrect statement.
2. 2Check whether the payee filed a return, included the income and paid tax, and whether an accountant's certificate exists. If yes, the deductor is not an assessee in default.
3. 3Compute interest. Count months from the due date to the date of deduction at 1%, then from deduction to payment at 1.5%. Treat part of a month as a full month.
4. 4Add the other consequences the question asks for: penalty under section 448 or section 461, and prosecution under section 477 if it is TCS collected but not paid.
5. 5Check the time limit and the good-and-sufficient-reason defence if the question hints at an old default or a genuine cause.
6. 6Write the answer in a tabular layout: heading, section, amount, with a one-line conclusion.

Common mistakes in Defaults, Interest, Penalty and Section 477 Failure

• Using 1.5% for the whole period.

  Students remember only the higher rate.

  Fix: Use 1% until the tax is deducted or collected and 1.5% from then until it is paid.

• Counting exact days or ignoring part months.

  Interest on other topics is sometimes calculated per day.

  Fix: Count every part of a month as a full month.

• Claiming that failure to deduct always means the deductor pays the tax.

  The relief under section 398(2) is overlooked.

  Fix: If the payee filed the return, included the income and paid tax, and the accountant's certificate is obtained, the deductor is not deemed in default.

• Applying the old minimum three-month rigorous imprisonment for TCS default.

  Older notes still show it.

  Fix: Under section 477 as substituted from 1 April 2026, punishment is simple imprisonment or fine, graded by amount. The old text (rigorous imprisonment of three months to seven years, and fine) no longer applies.

• Treating the section 461 penalty as a fixed sum.

  Students remember one figure and forget that the section gives a range.

  Fix: State the section 461 penalty as a range of ₹10,000 to ₹1,00,000, imposed by the Assessing Officer.

• Applying section 477 to tax deducted rather than tax collected.

  TDS and TCS are mixed up.

  Fix: Section 477 covers failure to pay tax collected at source. Tie it to section 397(3)(a).
