Every month, your employer deducts TDS from your salary. But how does the government know? Your employer files a report every quarter. That report used to be called Form 24Q. Now it's Form 138.
Form 138 is the quarterly TDS return that your employer files with the government to report how much salary was paid and how much TDS was deducted from all employees. It replaced Form 24Q from April 1, 2026. As an employee, you don't file this — but it directly affects whether your TDS credit shows up in Form 168.
You might think: "My employer files it, not me. Why should I care?"
Because your TDS refund depends on it. Here's the chain:
| Step | What Happens |
|---|---|
| 1 | Employer deducts TDS from your salary every month |
| 2 | Employer deposits TDS with government via challan |
| 3 | Employer files Form 138 quarterly — reporting TDS details |
| 4 | Government processes Form 138 and updates your Form 168 (AIS) |
| 5 | Employer issues Form 130 (TDS certificate) to you |
| 6 | You file ITR claiming TDS credit from Form 168 |
Samajh lo: if Step 3 doesn't happen, Steps 4-6 break. No Form 138 = No TDS in Form 168 = No refund.
| Section | What It Contains | Filed Every Quarter? |
|---|---|---|
| Part A | Deductor details — company name, TAN, address | ✓ Yes |
| Part B | Challan details — TDS deposited with government | ✓ Yes |
| Annexure I | Employee-wise TDS breakup — name, PAN, TDS amount | ✓ Yes (all 4 quarters) |
| Annexure II | Detailed salary computation — income, deductions, tax | Only Q4 |
| Annexure III | Senior citizen pension/interest (for specified banks) | When applicable |
Annexure II contains the full-year salary computation with all deductions. Since the complete picture is only available at year-end (January-March), it's filed only in Q4. This is also the annexure that feeds into your Form 130 Part C.
| Feature | Old: Form 24Q | New: Form 138 |
|---|---|---|
| Law | Income-tax Act, 1961 | Income-tax Act, 2025 |
| Annexures | 2 (Annexure I + II) | 3 (Annexure I + II + III) |
| Auto-prefill | ❌ Manual entry | ✓ Auto-prefill from challan data |
| Real-time Validation | ❌ Errors found after filing | ✓ Validated during filing |
| Generates | Form 16 | Form 130 |
| Updates | Form 26AS | Form 168 (AIS) |
| Quarter | Period | Due Date | Late Fee (Section 234E) |
|---|---|---|---|
| Q1 | April – June | July 31 | ₹200/day until filed |
| Q2 | July – September | October 31 | ₹200/day until filed |
| Q3 | October – December | January 31 | ₹200/day until filed |
| Q4 | January – March | May 31 | ₹200/day until filed |
The ₹200/day penalty is capped at the total TDS amount for that quarter. So if your employer's total TDS for Q1 was ₹50,000, maximum late fee is ₹50,000 — even if they filed 300 days late.
Neha earns ₹8 lakh salary. Her employer deducts ₹0 TDS (because ₹8L is within the zero-tax bracket under New Regime after standard deduction). But the employer still needs to file Form 138 every quarter — even when TDS is zero!
Why? Because Form 138 also reports the salary paid. If the employer doesn't file it, Neha's salary won't show up in Form 168. When Neha files ITR, the pre-filled data will be incomplete.
During your quarterly check of Form 168, if your salary details are missing, ask HR: "Has Form 138 been filed for this quarter?" Most payroll teams file on time, but small companies sometimes delay.
| Old Form | New Form | Who Files/Issues | Purpose |
|---|---|---|---|
| Form 24Q | Form 138 | Employer files quarterly | Report TDS on salary to government |
| Form 16 | Form 130 | Employer issues to employee | TDS certificate for employee |
| Form 26AS | Form 168 | Government generates | Complete tax statement for taxpayer |
Simple chain: Employer files 138 → Government creates 168 → Employer gives you 130 → You reconcile 130 vs 168 → File ITR. Done!
