Tax Deducted at Source (TDS) – The Complete Compliance Guide Every Business Must Understand

One unnoticed TDS mistake can cost a business more than the tax itself and most companies don’t even realise it until a notice arrives.

TDS seems simple on the surface  but a missed deduction, a late deposit, an incorrect section code, or a mismatch in Form 26AS can trigger compliance risks with interest, penalties, and unnecessary scrutiny.

This guide explains not just the rules, but the business impact, statutory timelines, penalties, and practical compliance actions every organisation must follow.

What Is TDS (Tax Deducted at Source)?

Tax Deducted at Source (TDS) is a mechanism under the Income Tax Act where the payer (deductor) deducts tax at the time of specified payments (like salary, rent, interest, professional fees, contractor payments) and remits the deducted amount to the government against the payee’s PAN. 

• Deductor: Entity making the payment
• Deductee: Entity receiving the income
• TDS is an advance collection mechanism, not additional tax

👉 Why this matters:
TDS embeds compliance into normal payment cycles; ignoring it doesn’t make it disappear it compounds risk.

Most Common Business Mistakes The TDS Risk Zone

Businesses often assume that deducting tax is enough but the law requires correct deduction, timely deposit, accurate filing, correct reporting, and reconciliation.

Typical compliance failures:

• Late TDS deposit: attracts mandatory interest charges.
• Late quarterly return filing: incurs a daily fee under Section 234E.
• Incorrect return filing or wrong details: may trigger discretionary penalties.
• Mismatch in Form 26AS: vendor or employee disputes, notices, delayed refunds.
• Failure to issue certificates on time : impacts employee/vendor tax credits.

👉 Brutal reality:

Many penalties grow from simple process lapses not “major errors.”

Applicability of TDS Statutory Thresholds & Sections

TDS applies only when:

• A specific section of the Income Tax Act covers the payment,
• Threshold limits are exceeded, and
• The deductee has not furnished Form 15G/15H where applicable.

Common payment categories include (but are not limited to) the following:

👉 Why this matters:

Incorrect classification of payment or wrong section code leads to return mismatches and notices.

TDS Rates & Thresholds Quick Overview (Indicative)

TDS rate and threshold depend on payment type, residential status, and PAN availability. These are prescribed under the Income Tax Act and updated each year.

Examples (illustrative only always verify with current schedule):

• Rent: 10% (typical for land/building)
• Professional services: 10%
• Contractor: 1–2% depending on deductor status

👉 Compliance tip:

Always validate current TDS rates at the start of each financial year.

Real-World TDS Example

Your business pays ₹80,000/month in office rent.

• Applicable Section: 194I
• TDS rate: 10%
• TDS deducted: ₹8,000
• Net paid: ₹72,000

The landlord still declares ₹80,000 as income and claims ₹8,000 as TDS credit from Form 26AS.

👉 Why businesses should care:

Deducting is only half the job ensuring that the deduction is reflected correctly in tax records is where compliance truly happens.

TDS Due Dates You Cannot Miss

TDS Deposit Due Dates

• Monthly deposition: By 7th of the following month after deduction.
• Special for March deductions: Extended to 30th or early April depending on the year’s rule.

Quarterly TDS Return Filing

TDS returns must be filed on a quarterly basis with the following deadlines:

👉 Important:

Deadlines are statutory missing them begins automatic penalties.

TDS Return Forms Correct Form Matters

Filing the wrong form can lead to return rejection or incorrect reports a common cause of mismatch notices.

TDS Certificates Issuance Deadlines

Deductors must issue valid TDS certificates:

Certificates are legal evidence of TDS credit for employees, vendors, and other payees.

Form 26AS The Single Source of Truth

Form 26AS shows all TDS deposited against a PAN. If a deduction does not appear here, it’s effectively not recognised for tax credit.

Key items in Form 26AS:

• TDS amounts deposited
• TCS (Tax Collected at Source)
• Advance tax or self-assessment tax paid

Mismatch between books and Form 26AS is one of the top triggers for scrutiny and notices.

Penalties & Interest The Cost of Non-Compliance

1. Interest for Late Deduction & Late Deposit

• 1% per month for late deduction (from when tax was deductible until actual deduction)
• 1.5% per month for late payment (from deduction until deposit)

Interest continues until the TDS is paid.

2. Late Filing Fee Section 234E

• ₹200 per day of delay after due date of return
• Capped at total TDS amount for that period

This fee is automatic when returns are filed late.

3. Penalty Section 271H

• ₹10,000 to ₹1,00,000 per default (discretionary)
• Applies if returns are filed late or with incorrect/false information

This penalty is in addition to Section 234E charges.

Important clarity:
If TDS is paid with interest and late fees, and returns are filed within one year of due date, the penalty under 271H may not be levied, provided the deductor has a reasonable cause and meets statutory relief conditions but this is often at officer discretion.
