Prepare 2025 Ohio school district withholding records

An Ohio personal return packet may need a separate review of school district income tax and withholding. The district where you lived, the income received during that period and the tax shown on your statements are different questions from your city income tax. This guide organizes 2025 records for a preparer; it does not determine your district, filing obligation, tax or refund.
The Ohio Department of Taxation's 2025 individual and school district return booklet contains the SD 100 instructions discussed here. Use the instructions and district information for the actual tax year. Do not carry a 2025 district rate, tax base or line instruction into another year without verification.
Identify where you lived
Write down each Ohio home address and the dates you lived there during 2025. Keep a lease, closing record or other documents that help establish the primary residence. The booklet says school district residency is based on the location of the primary residence, and not all school districts impose an income tax. Ask the preparer to verify the district and applicable year rather than relying on a postal city name or a work address.
The booklet states that only Ohio residents who lived in a taxing school district during some part of the year are subject to Ohio's school district income tax. It also says that working in a taxing district without living there does not by itself subject a person to that district's income tax. These statements do not determine an individual's residence; provide the actual facts for a qualified review.
If you moved between districts or filed jointly with a spouse who had different residence periods, give the preparer each person's timeline. The 2025 instructions describe a school district residency schedule and say one SD 100 is filed even when a taxpayer has liability for more than one district. Ask how the actual periods and any additional schedule pages should be reported. Do not assume that one year-end address covers the entire year.
Ask whether an SD 100 is required
The 2025 booklet says an SD 100 is required when all three stated conditions are met: you lived in a taxing school district for part of the year, received income while living there, and have a school district income tax liability based on that income. It also recommends filing in certain circumstances when a person lived in a taxing district and received income even if no liability is shown. Review the complete instructions and your facts; a wage statement alone is not a filing determination.
The booklet says a person may have school district income tax liability even without an Ohio income tax liability and, in that situation, must file both returns. Tell the preparer about any school district withholding, income and residence changes even if the state income tax calculation appears to be zero. Federal, Ohio state, school district and city returns answer different questions.
If you are uncertain about an earlier filing or a notice, keep the actual correspondence with the relevant year's documents and ask for a separate review. An estimated refund or an employer's withholding entry does not establish that a return was submitted or accepted.
Separate school district withholding from city withholding
Collect every W-2 and other income statement that reports school district withholding. The booklet says the district's four-digit number is generally shown in box 20 or box 14, and its Schedule of School District Withholding is used when reporting withholding on SD 100 line 11. It says not to include city income tax withheld on that school district schedule. Compare the district number, amount and taxpayer name with the underlying statement and ask about any mismatch.
If a statement contains more than one school district withholding amount, the 2025 instructions direct a separate line for each amount in the applicable schedule section. Keep all pages and corrected statements together. Do not merge a municipal withholding amount into a district amount merely because both appear in the local-tax area of a wage statement.
For example, a wage statement has a city entry and a separate school district entry. Give the preparer the full statement and the residence timeline, and ask which amount belongs on each return or schedule. This example identifies a review step; it does not establish that both entries are correct or that a refund is due.
If a municipal return is also relevant, the Cleveland city filing guide and Columbus city filing guide describe their respective local records. A school district determination does not decide either city's filing requirements; check the municipality and tax year that apply.
Match income to the district and tax base
The booklet distinguishes a traditional tax base from an earned-income tax base. Its earned-income description includes employee compensation and certain self-employment income to the extent included in modified adjusted gross income; it says retirement income, interest, dividends, capital gains and unemployment benefits are not earned income for that school district base. The district's actual tax type and the person's facts matter. Do not apply one district's base to another.
Where exact income or adjustment amounts are known for each residence period, the 2025 instructions say to match them to the proper district; they also describe a residency-factor method when exact amounts are not known. Preserve pay dates, residence dates and supporting records and ask the preparer which method applies. A simple equal split between districts is not a substitute for that review.
If you believe an employer withheld school district tax for the wrong district, identify the affected statements and periods. The booklet describes using SD 100 to request a refund of erroneous school district withholding and reporting all district withholding on one schedule. Ask the preparer to apply the actual withholding and liability; an error report alone does not guarantee a refund.
Complete the handoff
Give the preparer the Ohio return information, district residence timeline, income statements, withholding entries, estimated-payment records and any open questions. Confirm who will verify the district numbers and the appropriate-year instructions, prepare the state and district returns and retain filing confirmations.
Before signing, compare the residence periods and withholding amounts with the statements you supplied. If a corrected statement arrives later, provide both versions and ask whether further review is needed. This site does not verify a preparer, appointment or outcome. Use qualified help for your actual residence and income facts.
