Summary
Kurt Connick, Individual Income Tax Policy Director at the Iowa Department of Revenue, outlined common filing errors that delay processing and explained recent changes to Iowa forms and instructions.
At a recorded Iowa SourceLink webinar, Department of Revenue policy director Kurt Connick walked practitioners through form and filing details to reduce processing delays and errors.
“As a reminder, this presentation is for general educational purposes only. Nothing should be construed as legal advice,” Connick told attendees. He then listed routine errors that commonly slow department processing and how to avoid them.
Key filing and form guidance:
- Amended returns: Check the amended-return box and attach supporting forms (for example, a copy of the federal Form 1040 or relevant business/fiduciary returns) so staff can correctly classify and process the submission.
- Certificates of acquittance and processing time: The department’s recent system transition has increased processing times; Connick asked filers to wait 60 days before contacting the department about Form 1041-related certificates and to verify the power-of-attorney (POA) section is completed when appropriate.
- Estimated payments and voucher dates: Use the tax-year end as the voucher period date (e.g., 12/31/2025) when generating generic quarterly estimates; incorrect period dates (for example, 04/30/2025) can cause the department to hold payments until a matching return with the same period end is filed.
- PTET and vouchers: Partnership and S-corporation PTET payments must be made with the partnership or S-corp voucher types; do not use individual or composite vouchers or the payments will not connect.
- Credits and documentation: Double-check tax credit certificate numbers on the Iowa 148; transposed or incorrect certificate numbers will be denied because the department validates every credit it receives.
- Reporting changes: The department added a line to report the senior deduction on the Iowa 1040 (line 1f) and moved farm-tenancy exclusion reporting to Schedule 1 (line 18); the Iowa College Savings Plan deduction for 2025 is set at $5,800 per beneficiary (report on Schedule 1 line 14).
Connick encouraged preparers to retain worksheets (they do not need to be attached to the return) and to use GovConnectIowa for authorized lookups of client payment history. He also told farmers to check the qualifying-farmer box on the return and attach Form 2210f when required to avoid automatic underpayment penalties.
The webinar closed with host Megan Peasley reviewing contact resources: slides and the recording will be emailed and Taxpayer Services contact information was posted for unresolved or case-specific questions.
