| Type | Initialism |
The initialism TIA stands for Tax Information Authorization in tax-administration contexts. California’s Franchise Tax Board uses it for a relationship allowing a representative to review some confidential taxpayer information.
In the FTB context, information access is different from the authority to act on the taxpayer’s behalf to resolve a tax issue, which the agency distinguishes through a Power of Attorney, or POA. Online account access level is another separate question. Do not assume that the same initials establish identical powers or procedures across jurisdictions, or that a form title proves an authorization was approved.
Meaning in context
- Tax Information
- The information covered by the stated authorization context.
- Authorization
- A recorded permission relationship; its actual scope and approval are separate from the form’s title.
Practical examples
Keep authority precise
- Before
A California FTB TIA automatically gives all POA powers.
- After
FTB distinguishes a TIA information-access relationship from a POA declaration to act on the taxpayer’s behalf.
The two labels are not interchangeable descriptions of authority.
Separate draft and approval
- Before
The form is titled TIA, so the relationship is approved.
- After
The form title names the requested authorization; its actual approval and scope need separate confirmation.
A draft or submission and an approved relationship are different stages.
Original illustrative examples, not quotations or reports of actual events.
Use TIA with clarity
Does a TIA give the same authority as a POA?
See all guidance
Read the scope
Use the specific agency’s description.
California FTB’s TIA concerns access to some information.
Compare with POA
Preserve the agency’s authority-to-act distinction.
Access to information is not automatically authority to resolve an issue.
Read the status
Separate the form title from approval.
A submitted document does not establish an approved relationship.
The worksheet grants no access, submits no form and verifies no taxpayer, representative, permission or legal authority.
