T-FV-3175 NA Error Solution | TDS Late Filing Penalty Calculator

The T-FV-3175 NA error during TDS/TCS filing occurs when your File Validation Utility (FVU) is outdated or mismatched with the .csi (Challan Status Inquiry) file you are using.

What is the T-FV-3175 NA Error?

If you are filing TDS (Tax Deducted at Source) or TCS (Tax Collected at Source) returns in India, you may encounter the dreaded T-FV-3175 NA error code during FVU (File Validation Utility) validation. This error specifically indicates that:

• ❌ You are using an old version of the RPU (Return Preparation Utility) — typically below version 5.3
• ❌ Your Challan Status Inquiry (CSI) file is outdated or was downloaded before the latest RPU update
• ❌ There is a mismatch between the TAN database and your return file data

This error is most commonly reported during Form 26Q, 24Q, 27Q, and 27EQ filings. The Income Tax Department periodically updates the validation rules, making older RPU versions incompatible with the current filing requirements.

Error Code Breakdown

Step-by-Step Solution to Fix T-FV-3175 NA

🔴 Step 1: Download the Latest RPU Utility

The first and most critical step is to ensure you are using the latest version of the Return Preparation Utility (RPU). As of 2026, you need RPU version 5.3 or higher for seamless filing.

• Visit the official Protean-TIN portal
• Navigate to Downloads → e-TDS/e-TCS → Regular
• Download RPU 5.3 (or the latest available version)
• Uninstall any older RPU version from your system first
• Install the new RPU and restart your computer

⚠️ Pro Tip: Always check the RPU version before starting your return preparation. The version number is displayed in the RPU window title bar.

🟡 Step 2: Download a Fresh Challan Status Inquiry (CSI) File

The CSI file contains the latest challan status data from the Income Tax Department. Using an old CSI file is the second most common cause of T-FV-3175 NA.

• Go to the TIN-NSDL website (tin-nsdl.com)
• Login with your TAN and password
• Navigate to Downloads → Challan Status Inquiry
• Select the correct Assessment Year and Financial Year
• Download the .csi file (do NOT use an old downloaded file)

🔵 Step 3: Re-import CSI File into RPU

Once you have the fresh CSI file, you need to re-import it into the newly installed RPU.

• Open RPU 5.3
• Go to File → Import → Challan Details
• Browse and select the newly downloaded .csi file
• Verify that all challan details are correctly populated
• Save the RPU file with a new name to avoid confusion

🟢 Step 4: Regenerate and Validate the Return File

After re-importing the CSI file, regenerate your return file and validate it using the updated FVU.

• In RPU, go to File → Generate → Return File (.txt)
• Open the FVU (File Validation Utility) — also updated to the latest version
• Load the generated .txt file into FVU
• Run validation — T-FV-3175 NA should now be resolved
• If validation passes, proceed to upload on TRACES
