This form is used for two purposes:
• Tax information disclosure authorization. You authorize
the department to disclose your confidential tax infor-
mation to another person. This person will not receive
original notices we send to you.
• Power of attorney for representation. You authorize
another person to represent you and act on your behalf.
The person must meet the qualifications below. Unless
you specify differently, this person will have full power to
do all things you might do, with as much binding effect,
including, but not limited to: providing information; pre-
paring, signing, executing, filing, and inspecting returns
and reports; and executing statute of limitation extensions
and closing agreements.
This form is effective on the date signed. Authorization termi-
nates when the department receives written revocation notice
or a new form is executed (unless the space pr
ovided on the
front is initialed indicating that prior forms are still valid).
Unless the appointed representative has a fiduciary relation-
ship to the taxpayer (such as personal representative, trustee,
guardian, conservator), original Notices of Deficiency or
Assessment will be mailed to the taxpayer as required by
law. A copy will be provided to the appointed representative
when requested.
For corporations, “taxpayer” as used on this form, must be
the corporation that is subject to Oregon tax. List fiscal years
by year end date.
