I have all the details becoz I file tds return. Acutally I received notice u/s 234E 200 per day, We are a Govt Deductor but Department charge fine for late filling equal to Private sector.I don't have details of PAO/DTO/CDDO (AO). We deduct tds on 24Q & 26Q & deposit to Bank through bank challan. Customer Care from traces asked me to get 24G(don't know), Ain No. then we will be treated as Govt Deductor. When I try to online file AIN no through TIn - Nsdl site it ask details already provided to you.

Here’s a clear explanation about **AIN No.** and its relevance in filing TDS returns:
---
### What is AIN No.?
* **AIN** stands for **Account Information Number**. * It is a **unique 8-digit number** allotted by the Income Tax Department to **Government Deductors**. * It identifies the **PAO (Pay and Accounts Office), DTO (Drawing and Disbursing Officer), or CDDO (Central Designated Disbursing Officer)** responsible for the TDS deductions and payments made by government departments.
---
### Why is AIN No. Used in TDS Return Software?
* When filing **TDS returns** for government deductors (status code “S”), the **AIN No. is mandatory**. * It helps the Income Tax Department **identify the exact government office** responsible for deducting and depositing TDS. * Without a valid AIN, the TDS return file will **not be accepted** by the Income Tax Department (error in FVU file).
---
### How to Get AIN No.?
* AIN is allotted by the Income Tax Department when the government department registers as a deductor. * The government deductor needs to provide details of the **PAO/DTO/CDDO (AO)** during registration. * Usually, the **finance or accounts section** of the government office will have this number. * If you don’t have it, you must **contact the concerned government department or the Income Tax TDS helpdesk** for assistance.
---
### What if You Don’t Have AIN No.?
* You **cannot file TDS returns as a government deductor** without a valid AIN. * Filing as a private deductor or entering dummy AIN (like 00000000) will cause the return to be **rejected**. * The Income Tax Department may also levy **penalties (like section 234E penalty of ₹200 per day)** for late or incorrect filing.

### Summary:
| Aspect | Details | | --------------------- | ------------------------------------------------------------- | | What is AIN | Unique 8-digit Account Information Number for govt deductors | | Who needs AIN | Government deductors (status “S”) | | Purpose | Identify PAO/DTO/CDDO responsible for TDS deduction & deposit | | Obtaining AIN | From Income Tax Dept or govt department’s finance section | | Consequence of no AIN | TDS returns rejected; penalties may apply |
