The IRS handles federal taxes; the Ohio Department of Taxation administers state taxes, including individual income tax and school-district income tax. They maintain separate accounts and use different assessment and dispute procedures. Resolving an IRS notice does not, by itself, resolve an Ohio notice for the same year.
Identify the issuing agency, tax type, period, and account reference before choosing a form, making a payment, or requesting an appeal. A notice’s connection to an Ohio address does not make it a state tax matter. Likewise, a federal refund taken for a state debt does not necessarily mean the IRS assessed the disputed tax.
Compare the agencies by the action you need
| Issue | IRS | Ohio process |
|---|---|---|
| Typical account identifiers | Federal return type, tax year or period, CP or LTR number | Tax type, tax year or period, letter ID and assessment or collection reference |
| Disputing a notice | Procedure specified by that federal notice and case stage | For covered income-tax assessments, petition for reassessment under Ohio law |
| Requesting installments | IRS payment-plan application routes | The Department’s individual assessment instructions distinguish partial payment from an AGO arrangement |
| Later collection | Federal lien, levy, and applicable collection-appeal procedures | Final unpaid assessments may be certified to the Ohio Attorney General |
| Compromise | Federal offer-in-compromise requirements | Separate state program administered through the Attorney General |

An IRS notice is not an Ohio assessment
The IRS notice guide directs taxpayers to identify the CP or LTR number and follow the specific response instructions. Some letters request information; others adjust a return, demand payment, or explain collection rights. There is no single appeal form for all federal tax disputes.
Collection Due Process and the Collection Appeals Program concern particular federal collection actions. Their deadlines and protections are not Ohio reassessment rules. Sending an IRS collection-hearing form to Ohio does not create the state petition required by law.
Ohio assessment objections have their own requirements
For assessments covered by Ohio Revised Code 5747.13, a petition for reassessment is tied to service of the notice. The statute requires a timely signed petition stating the objections and contains circumstances in which payment is also required. A phone call asking for an explanation should not be treated as the petition.
The Department’s individual income-tax assessment instructions explain written and OH|TAX eServices submission, requesting a hearing, and the need for a required return in certain nonfiling cases. Calculate the applicable date from your notice and service facts, not an online specimen.
Other Ohio taxes may have different provisions. A business sales-tax matter, employer withholding issue, or municipal tax notice should not automatically be handled as an individual state income-tax assessment.
Payment authority can change after a state referral
The IRS offers payment-plan routes with eligibility and compliance requirements. The Ohio Department’s individual assessment instructions, by contrast, say it does not arrange payment plans for that assessment, although it credits partial payments.
If an unpaid Ohio assessment becomes final, it may be referred to the Attorney General’s collection office. Identify the current collector and account reference before sending a payment or proposal. The collection office may need records explaining a dispute even when you previously supplied material to Taxation.
An Ohio compromise application is separate from a federal offer. Do not assume the same forms, collection restrictions, payment terms, or appeal rights apply. A state payment plan also does not automatically stop an IRS levy.
One agency’s action can still affect the other return
Separate administration does not mean the numbers are unrelated. Under Ohio’s amended-return rules, a final federal adjustment affecting the state return can create an Ohio reporting obligation. Keep the federal report, final determination, and related dates so the state consequence can be evaluated.
Refund offsets create another connection. Ohio’s assessment instructions describe possible federal refund offsets for unpaid state debt. That reduces a refund through a collection mechanism; it does not merge the two liabilities or mean a dispute should be sent to whichever agency issued the refund.
Build a two-agency resolution checklist
For each account, record what is disputed, which returns are missing, where payments were credited, the deadline, and who is handling the next action. After a correction or agreement, obtain confirmation for that agency and reconcile its remaining balance.
