TDS Filing for Indian Businesses: Forms, Due Dates, Penalties, and What to Outsource (2026)

TDS is the compliance area where Indian small businesses consistently expose themselves to the most liability. Not GST, not ITR. TDS.

The reason is structural. With GST, you know exactly when your filing is due and the portal won't let you move forward without completing the current period. TDS is different. The obligation arises when you make a payment or credit an account, whichever is earlier. The deposit is due by the 7th of the following month (30th April for March deductions). The quarterly return is due 31 days to two months after the quarter ends. Most businesses get through several quarters without a problem and then assume TDS is running fine. It usually isn't.

I have seen clients receive demand notices for Rs 4 lakh in Section 234E late fees on returns they genuinely believed were filed. In two of those cases, the RPU file was prepared correctly but the upload failed silently, and the token number was never checked. In a third, the business had deducted under Section 194J but left the deductee PAN blank because the vendor had not yet shared it. The return was rejected. The re-filing was counted as a fresh filing, with the Section 234E meter already running from the original due date.

This is a guide for business owners and accounts teams who want to understand TDS filing end to end: which forms apply, what the due dates actually mean, how penalties compound, and where professional help pays for itself.

Which Businesses Are Required to Deduct TDS

Not every entity has TDS deduction obligations. The rules draw a specific line that trips up a lot of small businesses.

The individual and HUF exemption: An individual or HUF that is not subject to tax audit under Section 44AB is exempt from deducting TDS on contractor payments (Section 194C/393) and rent (Section 194I). This means a sole proprietor with gross receipts below Rs 1 crore (Rs 50 lakh for professionals) has no obligation to deduct TDS on, say, payments to a caterer or an office landlord. This exemption does not apply to salary TDS (Section 192/392) — every employer must deduct TDS on salary if the employee's annual income exceeds the exemption limit.

The turnover trigger: Once an individual or HUF crosses the tax audit threshold, TDS obligations switch on for all sections, including 194C, 194I, and 194J. A CA firm or a freelance designer who was exempt last year may have become a deductor this year without knowing it.

Companies, LLPs, partnership firms, trusts, and government bodies: These entities are always required to deduct TDS, regardless of turnover, for all applicable payment categories. There is no minimum size exemption.

Sections that apply to nearly every business:

Section 194C (now renumbered 393 under the Income Tax Act 2025) covers payments to contractors for any work, including advertising contracts, catering, housekeeping, labour supply, printing, and transportation. The threshold is Rs 30,000 per single payment or Rs 1 lakh aggregate in a financial year per contractor. TDS rate is 1% for individuals and HUFs, 2% for all other entities.

Section 194J (renumbered under the new Act) covers professional fees, technical services, royalties, and non-compete fees. The threshold is Rs 30,000 per payee per year. The rate is 10% for professional services and 2% for purely technical services since FY 2020-21.

If your business outsources any work or hires any professionals, one or both of these sections almost certainly applies.

TDS Forms: Which One Applies to Your Business

There are four main TDS/TCS return forms. Getting the right one matters because the TRACES portal does not auto-correct form selection errors.

Form 24Q covers TDS deducted on salary under Section 192 (now Section 392 under the Income Tax Act 2025). Filed by every employer who deducts TDS from any employee's salary in the quarter. Q4 includes Annexure II, the full-year salary computation that feeds Form 16 Part B. This is the one form where an error has a direct downstream impact on your employees — an incorrect Annexure II means they receive a wrong Form 16 and cannot reconcile their ITR.

Form 26Q covers TDS on all non-salary payments to residents. This includes Section 194A (interest), 194C (contractors), 194H (commission or brokerage), 194I (rent), 194J (professional and technical fees), 194N (cash withdrawals above Rs 1 crore), 194Q (purchases above Rs 50 lakh), and approximately 20 other sections. Most small and mid-size businesses file Form 26Q every quarter for their vendor, contractor, and professional fee payments.

Form 27Q covers TDS on payments to non-residents and foreign companies. If you have any offshore service providers — software vendors, consultants, cloud service providers — and the payments are subject to TDS under Section 195, you file Form 27Q. This is the form that most businesses forget until they receive a notice from the TDS officer.

Form 27EQ covers TCS (Tax Collected at Source) — a separate mechanism where the seller collects tax from the buyer at the time of sale. This applies to sellers of specified goods (scrap, timber, alcohol, minerals, motor vehicles above Rs 10 lakh) and to e-commerce operators and exporters in certain scenarios.

A note on section renumbering: The Income Tax Act 2025, which came into force on April 1, 2026 for most provisions, renumbers several TDS sections. Section 192 becomes 392, Section 194C becomes 393, Section 194J becomes 194J (retained with sub-sections). The TRACES portal and RPU software are being updated to reflect the new numbering. For FY 2026-27 returns, verify the section codes in the latest RPU version before filing.

Quarterly Due Dates — and Why Missing Them Is Expensive

The due dates for FY 2026-27 TDS returns are:

These dates are separate from the TDS deposit deadlines. TDS deducted must be deposited by the 7th of the following month. For deductions made in March, the deposit deadline is April 30 (not May 7). This March exception trips up businesses every year.

So the compliance sequence for a single contractor payment looks like this: deduct on the payment date, deposit by the 7th of next month, report in the quarterly return by the quarter's due date. Each step has its own penalty provision if missed.

The filing due dates are hard deadlines. There is no grace period, no form to request an extension for routine filings. The Section 234E late fee starts accruing from the day after the due date automatically, and the TRACES portal calculates it when you attempt to upload a late return. You cannot file without first paying the outstanding late fee through a separate challan.

Penalty Calculation: What You Actually Owe When You Miss a Deadline

This is where most businesses get a shock. The penalties are layered, they run concurrently, and they compound from dates that have nothing to do with when you discovered the problem.

Section 234E: Late Filing Fee

Rs 200 per day for every day from the due date to the date of actual filing, capped at the total TDS amount in the return.

Section 201(1A): Interest on Late Deposit

Two separate interest rates apply:

• 1% per month (or part thereof) if TDS was deducted late — measured from the date the deduction should have happened to the date it was actually deducted
• 1.5% per month (or part thereof) if TDS was deducted on time but deposited late — measured from the date of deduction to the date of deposit with the government

Interest is calculated on the TDS amount for each month or part of a month. Partial months count as full months.

Section 271H: Additional Penalty for Gross Non-Compliance

If a TDS return is not filed within one year from the due date, the Assessing Officer can levy an additional penalty of Rs 10,000 to Rs 1,00,000. This is over and above Section 234E. Section 271H does not apply automatically — it requires an order from the Assessing Officer and provides an opportunity to be heard. But once it is invoked, the minimum is Rs 10,000 regardless of the TDS amount.

A Real Calculation

Scenario: A Hyderabad-based private limited company pays a digital marketing agency Rs 5,00,000 in Q1 FY 2026-27 (April 2026). This payment falls under Section 194C (technical/advertising services). TDS at 2% = Rs 10,000.

The company deposits TDS on June 10 instead of May 7 (35 days late). It also files the Q1 Form 26Q on September 20 instead of July 31 (51 days late).

Section 201(1A) interest on late deposit:

• Deduction date: April payment date. Deposit date: June 10.
• That's two part-months: May (counted as full month) + June (partial month = full month). Total: 2 months.
• 1.5% per month x 2 months x Rs 10,000 = Rs 300.

Section 234E late filing fee:

• July 31 to September 20 = 51 days.
• Rs 200 x 51 = Rs 10,200.
• Capped at TDS amount of Rs 10,000.
• Fee = Rs 10,000.

Total additional cost: Rs 300 (interest) + Rs 10,000 (late fee) = Rs 10,300 on a Rs 10,000 TDS liability. The penalty has exceeded the tax itself.

This is not an unusual outcome. For businesses with large contractor payments and TDS amounts in the range of Rs 20,000 to Rs 50,000 per quarter, a 45-60 day delay in filing routinely doubles the total liability.

The Five TDS Mistakes That Generate the Most Notices

After handling TDS notices for businesses ranging from five-person startups to mid-size manufacturing units, the same errors appear repeatedly.

1. Depositing to the wrong minor head or using the wrong challan type. TDS deposits go to Challan 281. The challan has two sections: Company deductors (minor head 200) and Non-company deductors (minor head 400). A private limited company depositing under minor head 400 creates a mismatch that the system flags as an unmatched challan. The return then either rejects or shows the deductee's 26AS without the credit. This is a correction statement problem that takes 30-60 days to resolve.

2. Classifying contractor payments as professional fees. Section 194C (contractors) has a 2% rate for companies. Section 194J (professional services) has a 10% rate. Businesses routinely apply 194J to contractors providing software development, interior work, or logistics services because "it sounds more professional." The contractor then claims TDS credit at 10% in their ITR. When the actual section on the TDS certificate says 194C at 2%, there is a credit mismatch in their 26AS. The contractor calls the business. The business files a correction. Three months pass.

3. Not deducting on advance payments. The obligation to deduct TDS arises on payment or credit, whichever is earlier. If you advance Rs 2 lakh to a contractor before any work is done, TDS under Section 194C must be deducted on the advance. Many businesses deduct only when the final invoice is settled, leaving the advance payment undeducted. The TDS officer sees the advance in the bank statement (obtained through an AI-I inquiry) and raises a demand under Section 201(1) for TDS not deducted, plus interest under Section 201(1A) from the advance payment date.

4. Not deducting on deemed credits in books. Under the Income Tax Act, TDS must be deducted when an amount is "credited" to the payee's account or paid, whichever is earlier. Accrual entries count. If you book an audit fee payable of Rs 1 lakh in March to your statutory auditor but do not pay until May, TDS under Section 194J was due in March — not May. Businesses that run on cash accounting often miss deemed credits entirely.

5. Assuming low-value transactions are exempt. Section 194C has a threshold of Rs 30,000 per transaction or Rs 1,00,000 aggregate per year per contractor. These thresholds apply per contractor PAN, not per bill. Three invoices of Rs 40,000 each from the same vendor in a year cross the Rs 1 lakh aggregate threshold. TDS was due from the third invoice onwards, and arguably needed to be recalculated once the aggregate crossed the limit. Businesses tracking vendor payments by individual bill rather than annual aggregate consistently get this wrong.

What to Outsource vs Handle In-House

There is no universal answer, but there is a clear framework.

Handle in-house if:

• You have one or two employees and zero non-salary TDS obligations
• All your contractors are individuals below the Section 194C Rs 1 lakh aggregate threshold
• Your accounts team has prior TDS filing experience and actively uses TRACES

Consider professional support if:

• Your quarterly TDS liability across forms exceeds Rs 50,000
• You have five or more vendors, contractors, or professionals from whom TDS must be deducted
• Your business has a mix of salary and non-salary deductions (Form 24Q and Form 26Q both)
• You make payments to non-residents (Form 27Q)
• You have received even one TDS demand notice in the past two years

Outsource entirely if:

• You are a company with employees and multiple contractor relationships
• Your accounts team handles other priorities and TDS is a secondary task
• You have ever discovered a mismatch between your TDS challans and OLTAS records
• You cannot internally verify challan mapping, PAN validation, and return upload tokens after every filing

The TDS compliance cycle requires four distinct skills: accounting accuracy (getting deduction amounts right), systems knowledge (challan data, OLTAS, TRACES portal), tax law understanding (which section applies to which payment), and procedural discipline (filing on time, verifying upload tokens, downloading certificates promptly). A bookkeeper who is strong on accounting accuracy but unfamiliar with TRACES creates a specific failure mode. A firm that knows the sections but is stretched on time creates a different one.

In 2026, the TRACES portal has improved significantly. Corrections are faster. But the fundamental issue remains: TDS errors are backward-looking. By the time you discover a problem, Section 234E has been running for weeks or months. The cost of professional filing is almost always lower than the cost of one missed quarter's penalties.

Frequently Asked Questions

Who is required to deduct TDS in India?

All companies, LLPs, partnership firms, trusts, and government bodies are required to deduct TDS on applicable payments regardless of size. Individuals and HUFs are exempt from deducting TDS under Section 194C (contractors) and Section 194I (rent) only if they are not subject to tax audit under Section 44AB. Once turnover crosses Rs 1 crore (Rs 50 lakh for professionals), the tax audit threshold is crossed and TDS obligations apply in full. Every employer, regardless of entity type, must deduct TDS on salary payments if the employee's annual income exceeds the basic exemption limit.

What is the due date for TDS filing in India for FY 2026-27?

Quarterly TDS returns (Form 24Q, 26Q, 27Q, 27EQ) must be filed by July 31 (Q1), October 31 (Q2), January 31 (Q3), and May 31 (Q4). These are filing deadlines. TDS deposits must be made separately by the 7th of the month following deduction, with a special deadline of April 30 for March deductions.

What is the Section 234E late fee and how is it calculated?

Section 234E imposes a fee of Rs 200 per day for every day the TDS return remains unfiled after the due date. The fee accumulates from the day after the due date and is capped at the total TDS amount reported in the return. This fee must be deposited via challan before the return can be uploaded. For a return with Rs 30,000 in TDS filed 60 days late, the Section 234E fee would be Rs 200 x 60 = Rs 12,000, which is within the cap of Rs 30,000.

What is the difference between Section 234E and Section 201(1A)?

Section 234E is a late filing fee — it applies when the quarterly TDS return is filed after the due date. Section 201(1A) is interest on late deposit — it applies when TDS is either deducted late (1% per month from the date it should have been deducted) or deposited late after deduction (1.5% per month from the deduction date to the deposit date). Both can apply to the same default. Section 234E addresses the filing delay, while Section 201(1A) addresses the deposit delay.

Which form do I use for TDS on contractor payments — 26Q or 27Q?

Form 26Q is for TDS on payments to residents of India, including contractor payments under Section 194C. Form 27Q is for TDS on payments to non-residents and foreign companies under Section 195. If your contractor is an Indian resident entity or individual, use Form 26Q. If the contractor is a foreign company or NRI, use Form 27Q. Using the wrong form creates a credit mismatch in the payee's 26AS.

When must TDS be deducted on advance payments?

TDS must be deducted at the time of payment or credit of the relevant amount in the books of accounts, whichever is earlier. Advance payments count as payments. If you pay a contractor Rs 1 lakh as an advance before any invoice is raised, TDS under Section 194C must be deducted on that Rs 1 lakh at the time of payment. The common practice of deducting TDS only on final invoices, while leaving advances undeducted, creates a Section 201(1) demand for TDS not deducted and Section 201(1A) interest from the advance date.

What happens if a vendor does not provide their PAN for TDS purposes?

Under Section 206AA, if the deductee does not furnish their PAN, TDS must be deducted at the higher of: the rate specified for the section, the rate in force under the Finance Act, or 20%. For a contractor payment normally attracting 2% under Section 194C, the rate becomes 20% if the PAN is not provided. You cannot file the return with a blank or invalid PAN — the RPU will reject it during validation. The deductee loses TDS credit in their 26AS, and you bear the cost of the higher deduction.
