TDS return filing is the quarterly statement you send to the Income Tax Department confirming what tax you deducted, from whom and when you deposited it. You're not paying anything new when you file it you already deducted the tax and deposited it to the government days or weeks earlier. The return is just the paperwork that tells the department and your deductee's Form 26AS, that the deduction actually happened. That last part matters more than most business owners realise. Until your return is filed and processed, the person you deducted tax from can't claim credit for it in their own income tax return. We've had Chennai employers come to us in a panic every January because an employee couldn't file their ITR. The TDS was deducted and deposited months earlier, but the quarterly return was sitting unfiled, so it never showed up in the employee's Form 26AS. That's not a technical inconvenience. That's a business relationship problem. At Kanakkupillai, we take the heavy lifting off your shoulders when it comes to TDS return filing. From generating clean FVU files using the latest NSDL/TRACES utility to issuing Form 16 and 16A certificates on time, our tax team handles every step with absolute precision. TDS return filing is not a once-a-year task. It's quarterly, every year, for as long as your TAN stays active, and you've deducted any tax during that quarter. Miss a quarter thinking you'll "catch up annually," and the ₹200 per day late fee has already started counting before you've even noticed. Which form applies comes down to what kind of payment you deducted tax on: TDS deposit due date: by the 7th of the following month, for every month you deducted tax except tax deducted in March, which must be deposited by 30 April, not 7 April. Form 16 (salary certificate) due date: by 15 June following the end of the financial year. Form 16A (non-salary certificate) due date: within 15 days of the quarterly return's due date. TCS return (Form 143) due dates: now aligned to the same 31 July / 31 October / 31 January / 31 May schedule as TDS returns, unlike the earlier, earlier-in-the-month TCS-only dates under old Form 27EQ. Call +91 7305 345 345 or write to support@kanakkupillai.com - most Tamil Nadu clients get a same-week filing slot. These are the payment categories Tamil Nadu businesses run into constantly. FY 2026-27 filings, all of these now sit within Section 393 (non-salary TDS) or Section 392 (salary TDS) of the Income-tax Act, 2025. A valid TAN - your 10-digit Tax Deduction and Collection Account Number. Without an active TAN, you can't file anything, and every deductee's PAN gets tied to this number in the return. PAN details for every deductee - employees, contractors, landlords, whoever you deducted tax from. A single wrong digit here is the single most common reason a return bounces back or a Form 16A doesn't reconcile. Challan ITNS 281 details for every TDS deposit made during the quarter - the BSR code, challan serial number, and deposit date all need to match what the bank actually recorded. Payment-wise deduction details - the amount paid, the section under which tax was deducted, the rate applied, and the date of deduction Form 16/16A records from prior quarters, if you're reconciling or revising a previous filing Bank statements covering the TDS deposit transactions, to cross-check against the challans Digital Signature Certificate (for companies filing electronically) - if you don't already have one, we can issue a Digital Signature Certificate alongside your filing. deductee-wise payment details, challan records, and TAN/PAN information, checked against your bank statements before anything gets touched on a portal. matched to the right form for what you've deducted (Form 138/24Q, 140/26Q, 139/27Q, or 143/27EQ). this step catches PAN mismatches, invalid challan references, and formatting errors before the return ever reaches the department, skipping it is exactly how avoidable rejections happen. the validated file gets submitted, and you receive a token number as proof of filing the moment it's accepted. once the return is processed, certificates get generated and downloaded from TRACES never self-typed, since a self-generated certificate isn't valid proof of TDS credit. so if CPC-TDS flags a discrepancy, we catch it and file a correction before it turns into a notice. Send us your challan and deductee data, we'll validate, file, and hand you the acknowledgement, usually within 2-3 working days. Your deductees actually get their tax credit: A filed, processed return is what makes a deduction show up in someone's Form 26AS without it, an employee or vendor can't claim the credit in their own return, no matter how promptly you deposited the tax. You avoid the 234E/271H/40(a)(ia) stack entirely: Timely filing is the single cheapest form of tax planning available to a business with a TAN it costs nothing extra and prevents three separate, compounding consequences. Your compliance record stays clean for lenders and bigger clients: Banks and larger enterprise customers increasingly check TDS compliance history as part of onboarding or loan due diligence a pattern of late filings is a flag they notice. You catch data errors while they're still cheap to fix: A wrong PAN or challan reference is a five-minute correction before your return is processed. After a notice arrives, it's a much longer conversation. You get a clean paper trail if a deductee ever disputes a deduction: Filed returns and issued certificates are your evidence undocumented deductions are just your word against theirs. Treating it as an annual task: It's quarterly. A business that files once a year, thinking it's "catching up," has usually already accumulated three quarters of late fees before anyone notices. Quoting the old form numbers for FY 2026-27 periods: If your software or accountant is still generating a "Form 24Q" for a return covering April 2026 onward, that filing uses the wrong form and will get rejected it needs to be Form 138. Mismatching the PAN on file with the PAN on the deductee's actual card: This is the single most common cause of a return bouncing back or a Form 16A failing to reconcile with 26AS. Splitting job-work invoices incorrectly: TDS on a job-work payment applies to the labour/service component, not the material cost a distinction Coimbatore and Hosur manufacturers get wrong constantly when a vendor's invoice doesn't itemise the split. Assuming the builder or broker deducts property TDS: For property purchases above ₹50 lakh, it's the buyer's legal responsibility to deduct and deposit the 1% TDS not the seller's, and not an intermediary. Skipping a NIL return declaration: If you didn't deduct any TDS in a quarter but have filed in prior quarters, not marking that quarter as NIL can trigger an unnecessary compliance query later. Not reconciling against Form 26AS and AIS before filing: Most of the notices we help clients respond to trace back to a mismatch that reconciliation would have caught before the return was even submitted. Letting correction statements pile up: With the new 2-year cutoff on corrections, an error sitting unfixed for too long simply becomes uncorrectable there's no extension once that window closes. We'll review your last two quarters filings against 26AS for free catching a mismatch now costs nothing catching it after a notice arrives costs a lot more. Most of the TDS notices we help Tamil Nadu clients respond to don't start with an audit, they start with a mismatch between what you filed and what shows up in the deductee's Form 26AS or Annual Information Statement (AIS). A wrong PAN digit, a challan entered against the wrong quarter, or a section code typo is enough to trigger an automated discrepancy flag. Reconciling your TDS filings against 26AS and AIS before you file not after a notice arrives is the single most effective thing a business can do to stay out of this cycle. It ties directly into your broader Income Tax Return Filing, since a mismatch here delays refunds and credit for every deductee affected, not just your own filing. Error-checked before it ever reaches the department: we run FVU validation and PAN cross-checks on every return before submission, which is where most of the rejections and mismatches we see elsewhere would have been caught. Notice support, not just filing: if a mismatch or a 26AS discrepancy does trigger a query, we handle the response you're not left explaining a portal notice on your own months after the fact.

Frequently Asked Questions
Is TDS return filing an annual task or a quarterly one?
Quarterly, every quarter you've deducted any TDS, you file a return for it. There's no annual-only version of this filing. Treating it as a once-a-year task is the single most common (and expensive) mistake we see.What happens if I have a valid TAN but didn't deduct any TDS in a quarter?
You're not required to file a return for a quarter with zero deductions, but if you've filed in prior quarters, it's worth explicitly marking that quarter as a NIL return on the portal so your compliance record stays clean and doesn't trigger an unnecessary query.How do I correct a mistake in a TDS return I've already filed?
You file a correction statement, referencing the original return's token number. As of 1 April 2025, corrections must be made within two years from the end of the relevant financial year, there's a temporary relaxation for older periods running until 31 March 2026, after which unfixed errors in those old returns can no longer be corrected.Does property TDS apply to every property purchase in Tamil Nadu?
It applies when the property value is ₹50 lakh or more, and it's the buyer's responsibility, not the seller's, to deduct 1% TDS and deposit it, using a PAN-based process rather than the regular quarterly return. We see this missed constantly in Chennai's resale market.What's the difference between the daily late fee and the discretionary penalty?
The daily late fee (₹200/day, capped at your TDS amount) is automatic, no discretion involved. The discretionary penalty (₹10,000 to ₹1,00,000) is separate, imposed at the Assessing Officer's discretion for late or incorrect filing, and both can apply to the same late return at the same time.Do the old form names, 24Q, 26Q, 27Q, 27EQ still matter?
For anything relating to FY 2025-26 or earlier, yes, use the old form numbers. For FY 2026-27 onward, the same filings go under the new numbers: Form 138, 140, 139, and 143 respectively. Both sets of names are worth knowing, since you may be filing corrections against old-numbered returns while filing current-period returns under the new numbers.Can a small business with just two or three employees skip TDS filing?
No, there's no size threshold. If you've deducted any tax on any payment, salary or otherwise, and you hold a TAN, quarterly filing applies to you regardless of company size.What makes Us Different
