TDS & TCS Due Dates (FY 2026-27): Complete Compliance Guide for CAs & CFOs
Statutory Framework & Legal Background
Tax Deducted at Source (TDS) and Tax Collected at Source (TCS) form the bedrock of advance tax collection under the Income Tax Act, 1961. Governed strictly by Sections 200, 206C, and Chapter XVII-B, deductors and collectors are mandated to furnish quarterly statements within prescribed statutory timelines. Non-compliance with these filing windows triggers severe penal consequences:
- Late Filing Fee (Section 234E): A mandatory fee of ₹200 per day is levied for every day the failure continues, capped at the total amount of tax deductible/collectible.
- Default in Deduction/Collection (Section 201/206C(6)): Assessees are treated as assessees-in-default, attracting penal interest ranging from 1% to 1.5% per month or part thereof.
- Disallowance of Expenses (Section 40(a)(ia)): 30% of expenses claimed by business entities are disallowed in computing business income if TDS is not deducted or, having been deducted, is not paid on or before the due date specified under Section 139(1).
Scope of Applicability & Return Filing Matrix
The statutory return filing requirements apply universally to all corporate entities, non-corporate businesses, government departments, and individuals/Hindu Undivided Families (HUFs) subject to tax audit under Section 44AB who make specified payments (salary, contractor fees, rent, professional charges) or collect tax on specified goods (scrap, timber, foreign remittance under LRS, sale of goods above specified thresholds).
The scheduled quarterly due dates for filing Form 24Q (Salary), Form 26Q (Non-Salary), Form 27Q (Foreign Payments), and Form 27EQ (TCS) for Financial Year 2026-27 (Assessment Year 2027-28) are structured as follows:
- 1st Quarter (April to June 2026): Due on 31st July 2026
- 2nd Quarter (July to September 2026): Due on 31st October 2026
- 3rd Quarter (October to December 2026): Due on 31st January 2027
- 4th Quarter (January to March 2027): Due on 31st May 2027
Step-by-Step Operational & ERP Workflow
To eliminate manual intervention and reconcile TRACES defaults with Books of Accounts, finance teams must implement a robust ERP workflow:
- Vendor Master Validation: Enforce mandatory PAN verification and linkage with Aadhaar at the onboarding stage to prevent higher tax deduction under Section 206AA and 206AB.
- Automated Tax Trigger: Configure ERP sub-ledgers to calculate TDS/TCS at the exact point of invoice booking or payment settlement, whichever is earlier, strictly adhering to Section 194-series thresholds.
- Challan Mapping: Ensure BSR codes, challan identification numbers (CIN), and major head codes (0020 for companies, 0021 for non-companies) are accurately mapped to quarterly deduction entries before statement preparation.
- FVU Validation & Generation: Process Return Preparation Utility (RPU) files through the National Securities Depository Limited (NSDL) File Validation Utility (FVU) to detect structural errors prior to upload.
- TRACES Reconciliation: Download Form 26AS and AIS data post-filing to verify credit reflection against vendor PANs, mitigating mismatch notices under Section 200A.

- ✔ Audit Trail Review: Verify that monthly TDS/TCS deductions match general ledger liability accounts across all accounting periods.
