Information for Tax Preparers

The Arizona Department of Revenue (ADOR) staff strives to ensure return preparers file complete and accurate income tax returns.

The following program requirements will help with the process.

Tax preparers are responsible for ensuring they comply with all applicable laws. Per Arizona Revised Statute § 42-1103.03, ADOR can suspend a return preparer from participating in the electronic filing program if staff determines the electronic return preparer has failed to comply with the electronic filing program requirements as outlined under the following Arizona Revised Statutes:


Additionally, Arizona Revised Statute § 42-1103.01 authorizes ADOR to apply to the tax court to enjoin any return preparer from engaging in business if the return preparer has engaged in other fraudulent or deceptive conduct that substantially interferes with the administration of title 42 or 43.

Violations of the electronic filing requirements include, but are not limited to:

  • Filing returns that report fictitious or inflated expenses (reporting inaccurate expenses on the 1040 Schedule C, Schedule E, 1120, 1120S, etc.)
  •  Claiming credits for which the taxpayer does not qualify (Donation to Qualifying Charitable Organizations, Research and development credit, etc.)
  • Reporting inaccurate deductions (Schedule A deductions, above-the-line deductions, etc). 
  • Any failure, by the preparer, to exercise due diligence in the preparation of the tax return.

The above list of actions or omissions that may qualify as violations of the electronic program is for illustration purposes only.  Other situations not listed may also qualify as violations of the program.

See GTP 20-1
