SAS ID vs EPID: What Is the Difference in BBMP Records?

Compare SAS ID vs EPID in BBMP records. Learn the difference between SAS number, PID, ePID, property tax use, and e-Khata property identification.
Quick Summary: (TL;DR)
SAS ID and EPID are not the same. SAS ID is mainly tied to BBMP property tax under the Self Assessment System. EPID is tied to the property’s digital identity in e-Khata and property-record systems. One helps you track tax records. The other helps identify the property itself.
SAS ID vs EPID: The Quick Difference
Here is the simplest way to understand it:
• SAS ID is mainly for the property tax record
• EPID is mainly for the property identity record
People often confuse them because both numbers may appear in BBMP-related property work. But they do different jobs.
SAS ID vs EPID Table
Point | SAS ID | EPID |
Full meaning | Self Assessment System reference | Electronic Property ID / e-property identifier |
Main use | Property tax assessment and payment records | Property identification in digital property and e-Khata systems |
Usually linked with | Tax return, challan, receipt, payment history | Property details, e-Khata status, digital municipal record |
Portal context | BBMP property tax portal | BBMP e-Aasthi / e-Khata side |
What it answers | “Which tax record is mine?” | “Which property record is mine?” |
Common confusion | Mistaken for PID or property ID | Mistaken for SAS or tax number |
What Is SAS ID in BBMP?
SAS stands for Self Assessment System.
In the BBMP property tax process, the SAS number or SAS base application number acts as a tax-reference number. Owners use it when they want to retrieve an old return, continue payment, print a receipt, or check an earlier tax record.
BBMP’s online property tax guide asks users to enter the Base SAS application No. or PID No. during the filing flow. That shows clearly that SAS belongs to the tax-assessment side.

What Is EPID in BBMP Property Records?
EPID is used more on the property-identity side than on the tax-return side.
In the BBMP e-Aasthi and e-Khata environment, owners can track services such as:
• Final eKhata status based on ePID
• New eKhata status based on ePID
• Property-related digital record services
That makes the role of EPID quite clear. It helps the system point to the correct property record in the digital property database.

Is EPID the Same as PID Number?
In everyday property discussions, people often use EPID, PID, and property ID loosely. But it is safer to think of EPID as the digital property identity reference used in the e-Khata and property-record side.
BBMP’s GIS Enabled Property Tax Information System explains that all mapped properties have unique PIDs, and these PIDs define ward, street, and house number details. So when owners talk about EPID, they are often talking about the same broader property-identification side of the record system.

When Should You Use SAS ID?
Use SAS ID when your work is mainly about tax.
Typical cases include:
• Paying BBMP property tax
• Checking previous payment history
• Printing challan
• Printing receipt
• Tracing earlier self-assessment returns
If your question is, “How do I continue my tax record?” you are usually in SAS territory.
When Should You Use EPID?
Use EPID when your work is mainly about identifying the property inside the digital property system.
Typical cases include:
• Checking e-Khata status
• Tracking digital property records
• Verifying whether the correct property entry exists
• Connecting municipal property identity with the right record
If your question is, “Which digital property record belongs to my site, flat, or house?” you are usually in EPID territory.
Why Do People Confuse SAS ID and EPID?
Because both are used in BBMP-related work, and both may appear during property tax, e-Khata, or documentation discussions.
The confusion gets worse when families only have partial documents such as:
• One old tax receipt
• One khata copy
• One sale deed
• No clear note about which number is which
Once that happens, people start treating every property number as if it means the same thing. That is where mistakes begin.
Which One Matters More for Property Tax Payment?
For direct BBMP property tax work, SAS ID is more closely tied to the tax-return and payment process.
But PID can also matter because BBMP’s own tax workflow allows users to proceed with either the Base SAS application No. or PID No.. That means tax work can still touch the property-identification side.
So the better answer is:
• SAS ID matters more for tax history and assessment flow
• EPID / PID matters more for property identification
• Both can become relevant in linked BBMP workflows
