What is Form 24Q?

Form 24Q is the quarterly statement employers file with the Income Tax Department for TDS deducted on salary payments under Section 192. It contains employee-wise details of salary paid and tax deducted during the quarter.

Quarterly due dates (FY 2025-26)

  • Q1 (Apr–Jun): 31 July
  • Q2 (Jul–Sep): 31 October
  • Q3 (Oct–Dec): 31 January
  • Q4 (Jan–Mar): 31 May

Q4 is the annual reconciliation — it includes Annexure II with full-year salary details for every employee. Q1–Q3 contain only Annexure I (challan-wise TDS deductions).

Annexure I — challan-wise details

For every TDS challan paid during the quarter, list:

  • Challan serial number, BSR code, date of deposit
  • Total TDS amount deposited
  • Section codes (192 for salary)
  • Employee-wise PAN, salary paid, TDS deducted, date of credit

Annexure II — full-year salary breakdown (Q4 only)

For every employee on payroll during the year, Q4 Annexure II requires:

  • PAN, name, period of employment
  • Total salary breakdown (Basic, HRA, perquisites, allowances)
  • Section 10 exemptions (HRA, LTA, gratuity, etc.)
  • Standard deduction, professional tax
  • Section 80 deductions (80C, 80D, 80E, etc.)
  • Total tax payable, TDS deducted, balance refund/payable

Common Form 24Q errors

  • PAN mismatch — wrong PAN format or not validated against Income Tax DB. Use TIN-NSDL bulk PAN verification before filing.
  • BSR code error — challan paid via wrong bank or BSR code mismatch with paid challan.
  • Section 87A rebate calculation — Old vs New regime threshold (₹5L vs ₹7L) and rebate amount (₹12,500 vs ₹25,000) confusion.
  • Surcharge not added — for income above ₹50L (10%) or ₹1Cr (15%) or ₹2Cr (25%) or ₹5Cr (37%, capped at 25% under New regime).
  • Cess (4%) missing — health & education cess always 4% on income tax + surcharge.

How PeopleOS automates Form 24Q

Every TDS payment is recorded against its challan. At quarter-end, PeopleOS:

  1. Generates Annexure I from the quarter's challans
  2. For Q4, additionally generates Annexure II from the full-year payroll ledger
  3. Validates all PANs against the live IT department API
  4. Produces the FVU (File Validation Utility) compatible TXT file ready for upload to TIN-NSDL or ITD's e-filing portal
  5. Issues Form 16 to all employees within 15 days of Q4 filing

Penalties for late filing

  • Section 234E: ₹200 per day of delay (capped at the TDS amount itself)
  • Section 271H: ₹10,000 to ₹1,00,000 for failure to file or for filing inaccurate returns (added on top of 234E)
  • Disallowance of expense: 30% of the salary expense disallowed under Section 40(a)(ia) if TDS not deposited / not reported

The compounding penalties make late Form 24Q filing one of the most expensive HR compliance failures. PeopleOS sets up automated reminders 14, 7, and 3 days before each quarterly deadline.
