How TDS Rates Are Decided: Income Tax Act, Finance Act & DTAA

Updated: Apr 28, 2026 12 min read Rithesh Bajoriya
Quick Summary
  • TDS rates in India are set by the Income Tax Act, the Finance Act, and Double Taxation Avoidance Agreements (DTAA).
  • The Income Tax Act provides the basic rules and rates for TDS on various types of payments like salary and rent.
  • The Finance Act can change TDS rates annually with updates that start on April 1 each year.
  • DTAAs help avoid double taxation and may allow lower TDS rates if the taxpayer provides the right documents.
  • When conflicts arise, DTAA rates take precedence if proper documentation is provided; otherwise, the Finance Act rates apply.

Tax Deducted at Source (TDS) is one of the key ways the Indian government collects income tax in advance. The TDS rate in India is not fixed for all time; it is guided by three important pillars: the Income Tax Act, the Finance Act, and Double Taxation Avoidance Agreements (DTAA). Here’s a detailed look at how these factors work together to determine TDS rates.

Importance of TDS in Taxation

TDS ensures that taxes are collected at the source of income. It helps maintain a steady flow of revenue to the government and prevents large year-end tax liabilities for taxpayers. Correct TDS rates also reduce the risk of underpayment or overpayment of taxes.

TDS under the Income Tax Act

Legal foundation of TDS rates

The Income Tax Act, 1961, provides the basic legal framework for TDS in India. It defines who must deduct TDS, the nature of payments covered (salary,  rent , interest, etc.), and the base rates.

Role of the Income Tax Act in defining applicable rates

Different sections of the Act, like Section 192 (salary), 194A ( interest ), or 194I (rent), specify the standard TDS rates and conditions for deduction.

TDS under the Finance Act

Annual budget provisions impacting TDS

Every year, the Union Budget introduces a Finance Act that can revise TDS rates, add new sections, or modify thresholds. These changes apply from the new financial year starting April 1.

How Finance Act updates existing TDS rates

For example, the Finance Act might increase the TDS rate on certain  professional fees  or lower the threshold for TDS on  cash withdrawals . These updates override older provisions in the Income Tax Act for that year.

TDS under DTAA (Double Taxation Avoidance Agreement)

Meaning and purpose of DTAA

A DTAA is an agreement between India and another country to avoid double taxation on the same income. It allows a taxpayer to pay tax either in India or the other country—or at a reduced rate.

When DTAA overrides domestic law

If a DTAA exists, the taxpayer can use the lower TDS rate specified in the treaty instead of the standard Income Tax Act or Finance Act rate, provided they furnish required documents like a Tax Residency Certificate.

Examples of DTAA benefits for taxpayers

For instance, India’s DTAA with the USA sets a 15% TDS on royalties, which can be lower than the domestic rate.

Comparison of Act, Finance Act, and DTAA

Key differences in applicability

  • Income Tax Act: Provides the base rules and rates.
  • Finance Act: Revises these rates each year.
  • DTAA: Offers relief for cross-border transactions.

Which one takes precedence in case of conflict

If all three apply, DTAA rates prevail if the taxpayer provides valid documentation. Otherwise, the Finance Act’s latest rates are used.

Practical example for residents vs. non-residents

  • Resident: Pays TDS as per the latest Finance Act.
  • Non-Resident: May pay a lower rate if the DTAA with their country specifies a reduced rate.

Compliance and Documentation

Importance of referencing the right section

Always deduct TDS using the correct section of the Income Tax Act to avoid penalties.

Certificates and forms (Form 15CA, 15CB in case of DTAA)

When claiming DTAA benefits, the taxpayer must submit Form 15CA (declaration) and Form 15CB (chartered accountant certificate) to ensure proper compliance.

Conclusions

The Income Tax Act shapes TDS rates in India as the foundation, updated each year by the Finance Act, and fine-tuned by DTAAs for cross-border income. Staying aware of these three elements ensures accurate deductions and smooth tax compliance.
