Frequently-Asked Questions

How do I represent a client before LDR?

To discuss confidential taxpayer information or act on behalf of a taxpayer, LDR must have a valid authorization on file. Depending on the services requested, this may require Third-Party Access through LaTAP, a valid Power of Attorney, or another authorized disclosure.

What's the difference between Third-Party Access and a Power of Attorney?

Third-Party Access allows authorized representatives to access approved taxpayer accounts electronically through LaTAP.

Power of Attorney (Form R-7006) authorizes a representative to communicate and act on behalf of a taxpayer for specified Louisiana tax matters.

Can I manage multiple clients?

Yes. Tax professionals may manage multiple client authorizations and accounts when appropriate authorization has been granted.

Where can I find the latest tax guidance?

Revenue Information Bulletins, Revenue Rulings, and adopted administrative rules are published on the LDR website and provide official guidance on Louisiana tax administration.

How do I update or revoke a Power of Attorney?

Submit an updated authorization or revocation using the current Louisiana Tax Power of Attorney process. A new authorization may replace an existing authorization depending on the changes requested.

Where can I find Louisiana tax forms?

The Tax Forms library provides the most current Louisiana tax forms, schedules, instructions, and publications.
