What is TDS?

Tax Deducted at Source - defined for the India income-tax context, not the water-quality measurement that shares the acronym.

In brief

TDS means Tax Deducted at Source in India. For specified payments, the payer deducts tax when the applicable conditions are met, deposits it with the government and reports it against the payee. The governing provision, threshold and rate depend on the payment, payee and current law; TDS is not one universal percentage.

01

How does TDS work?

The payer first determines whether the payment, payee and threshold fall within a withholding provision. If they do, tax is deducted at the applicable trigger, the balance is paid to the payee, and the deduction is deposited and reported so the payee can receive credit.

The calculation is simple only after the legal inputs are correct. A rate calculator cannot determine the nature of payment, residential status, threshold aggregation, lower-deduction certificate or whether a special condition applies. Those facts must be confirmed before entering a rate.

  • Classify the payment and payee.
  • Check the applicable threshold and governing provision.
  • Use the confirmed rate at the correct trigger.
  • Deposit, report and reconcile the credit record.

What changed on 1 April 2026?

The Income Tax Department states that payments or credits on or before 31 March 2026 remain governed by the Income Tax Act, 1961, while amounts paid or credited on or after 1 April 2026 use the corresponding withholding provisions of the Income Tax Act, 2025.

For non-salary payments under the new Act, the department’s transition FAQ directs deductors to the relevant table item of section 393. Continuing to quote old identifiers such as 194C, 194J or 194H for post-transition transactions may cause validation errors. The underlying earlier-of-credit-or-payment trigger continues to matter.

  • Through 31 March 2026: Income Tax Act, 1961 identifiers.
  • From 1 April 2026: Income Tax Act, 2025 withholding provisions.
  • Non-salary table reference: section 393.

When is deducted tax deposited?

The department’s transition FAQ says the general deposit timeline remains the 7th of the month following deduction. For TDS deducted in March, the stated due date for a non-government deductor is 30 April; government-deductor treatment has its own conditions.

A business should still verify the rule, challan, tax year and deductor category for the actual transaction. A calendar reminder is not enough if the original payment was classified under the wrong provision or the deposit is posted against the wrong year during the transition.

  • General reference: 7th of the following month.
  • March deduction, non-government deductor: 30 April.
  • Select the correct Act, tax year and payment code.

What are the stated interest rates for delay?

The Income Tax Department records interest at 1% per month or part of a month for failure to deduct when tax was deductible. It records 1.5% per month or part for failure to deposit after deduction. These figures describe interest for default; other consequences and conditions can also apply.

The operational distinction matters. A deduction made late and a deduction made on time but deposited late are different states. Finance should retain the original trigger date, actual deduction date, deposit date, amount and responsible owner instead of recording both as one generic overdue task.

  • Failure to deduct: 1% per month or part.
  • Failure to deposit after deduction: 1.5% per month or part.
  • Retain trigger, deduction and deposit dates separately.

Worked example: calculate after confirming the rate

Assume the amount subject to TDS is ₹100,000 and the responsible reviewer has confirmed an applicable rate of 10% for the specific transaction. The arithmetic produces TDS of ₹10,000 and a net payment of ₹90,000.

The example demonstrates the calculation, not that 10% applies to every professional, contractual or other payment. The source record should retain the payment classification, threshold test, payee status, governing table item, rate basis and any certificate before the result enters a payment or invoice record.

  • Amount subject to TDS: ₹100,000
  • Confirmed illustrative rate: 10%
  • TDS: ₹10,000
  • Net payment: ₹90,000

Common questions

Clear answers without the detour.

What does TDS stand for?

TDS stands for Tax Deducted at Source in the India income-tax context. It describes tax withheld by a payer from specified payments when the applicable legal conditions are met. The acronym can also mean total dissolved solids in water testing, but that is unrelated. This page and calculator deal only with India tax withholding.

Is there one TDS rate for every payment?

No. The applicable provision, threshold and rate depend on the nature of payment, payee, residential status, timing, available identifiers and any lower- or nil-deduction certificate. A calculator should use a rate already confirmed for the transaction. It cannot decide classification or legal applicability from the payment amount or invoice description alone.

Which law applies to TDS after 1 April 2026?

The Income Tax Department says payments or credits on or after 1 April 2026 use the withholding provisions of the Income Tax Act, 2025. Non-salary deductors should use the relevant table item under section 393 rather than old section identifiers. Transactions triggered on or before 31 March 2026 remain governed by the earlier Act.

When is TDS generally deposited?

The department’s transition FAQ retains the general timeline of the 7th of the month following deduction. For TDS deducted in March, it states 30 April for non-government deductors. The exact treatment can depend on deductor category, transaction and current rules, so verify the official position and select the correct Act and tax year.

What interest applies when TDS is delayed?

The official FAQ states 1% per month or part for failure to deduct tax when it was deductible, and 1.5% per month or part for failure to deposit after deduction. These are distinct defaults measured from different dates. Other consequences may apply, so retain the trigger, deduction and deposit records and verify the current rule.
