ARIZONA STATE SENATE
Fifty-Seventh Legislature, Second Regular Session
AMENDED
tax returns; late filing; penalties
Purpose
Retroactive to January 1, 2026, prohibits a late filing penalty from being assessed on a taxpayer if the taxpayer's income tax liability is zero.
Background
If a taxpayer fails to make and file a tax return by the due date, the penalty is 4.5 percent of the tax required to be shown on the return which must be added to the tax for each month or fraction of a month elapsing between the return's due date and the date the return is filed. The total late filing penalty may not exceed 25 percent of the tax found to be remaining due.
If a taxpayer fails or refuses to file a return on notice and demand by
the Arizona Department of Revenue (ADOR), the taxpayer must pay a penalty of 25
percent of the tax in addition to any late filing penalty. ADOR may abate the
late filing and notice and demand filing penalties when it is found that the
failure is due to reasonable cause. Reasonable cause means a reasonable
basis for the taxpayer to believe that the tax did not apply to the business
activity or the storage, use or consumption of the taxpayer's tangible personal
property in Arizona (A.R.S.
§ 42-1125).
Except as otherwise outlined, monies received for and belonging to the state are deposited in the state treasury and credited to the state General Fund (A.R.S. § 35-142). If prohibiting late filing penalties from being assessed when tax liability is zero results in a change to civil penalty revenues that would have otherwise been collected and deposited in the state General Fund, there may be a fiscal impact to the state General Fund associated with this legislation.
Provisions
1. Prohibits a late filing penalty from being assessed on a taxpayer if the taxpayer's income tax liability is zero.
2. Becomes effective on the general effective date, retroactive to January 1, 2026.
Amendments Adopted by Committee
· Removes the late filing penalty exemption for transaction privilege tax taxpayers.
