Ohio Form IT-561, officially titled the “Ohio Capital Gain Deduction Schedule,” is the form Ohio resident, part-year, and nonresident individual income taxpayers file with their Ohio IT 1040 return to claim the new capital gain deduction created by Ohio Revised Code 5747.79. The form lets a qualifying investor subtract gains from the sale of an ownership interest in a qualifying Ohio venture-backed business from Ohio adjusted gross income, which can lower taxable income to zero on those specific gains.
The form is small but unforgiving. The Ohio Department of Taxation reports that capital gain deduction claims have grown sharply since the deduction expanded under House Bill 33, and roughly 1 in 5 first-year filers had their deduction adjusted or denied due to missing certifications, wrong holding periods, or basis errors, according to guidance circulated through the Ohio Department of Taxation tax alerts.

What Ohio Form 561 Is and Who Must File It
Ohio Form 561 is the schedule the Ohio Department of Taxation uses to verify a taxpayer’s claim under the capital gain deduction in ORC 5747.79. The deduction was created to reward long-term investors who hold equity in Ohio-based, venture-backed operating companies. Without the form, the deduction line on the Ohio Schedule of Adjustments is treated as unsupported and removed during return processing.
The form is filed by individuals, not by corporations. A C-corporation reporting its own gain does not use Form 561. A pass-through entity owner who receives a qualifying gain on a federal Schedule K-1 does file Form 561, because the gain flows through to the individual return. Trusts and estates use the parallel deduction on the Ohio IT 1041 and a different schedule, not Form 561.
You must file Form 561 if all four conditions are met. First, you sold an ownership interest in a qualifying Ohio venture-operating business. Second, you held the interest for the required period. Third, you reported the gain on your federal Form 1040 Schedule D. Fourth, you are claiming the deduction on Ohio Schedule of Adjustments, line for “Ohio capital gain deduction.” Filing without meeting all four invites a notice of proposed assessment under ORC 5747.13.
Form 561 also serves a documentation purpose. It records the seller’s basis, the qualifying-business certification, and the apportionment of gain to Ohio. The Department uses these entries to cross-check against Ohio Department of Development venture capital reports and federal data.
The form is short — typically two pages plus instructions — but every line is consequential. The current version is dated Rev. 11/25 for the 2025 tax year. Confirm you have the correct revision before you start, because a 2024 version will not carry the new tier limits.
Before You Start: Documents and Information You Need
Form 561 is a verification form. Most rejections happen because the filer cannot prove what they entered. Gather everything below before you open the form, because each item maps to a specific line.
- Federal Form 1040 Schedule D and Form 8949. These show the gross gain you reported to the IRS. Without them, the Department cannot reconcile your Ohio entry. A missing Schedule D triggers an automatic deduction denial.
- Brokerage 1099-B or closing statement. This proves the sale date and proceeds. Filers who use estimates instead of the 1099-B routinely report the wrong holding period.
- Original purchase documents (basis records). You need cost basis for the ownership interest. Wrong basis is the single largest source of adjusted deductions.
- Qualifying Ohio business certification. This is a written statement from the company (or its successor) confirming it met the operating-business and Ohio-headquarters tests during your holding period. Without it, the deduction is denied on review.
- Holding-period proof. A stock ledger entry, subscription agreement, or capital account statement showing the date you acquired the interest. The deduction requires a continuous holding period that meets the statutory minimum.
- Schedule K-1 (if pass-through). Required if you held the interest through an LLC or partnership.
- Prior-year Ohio IT 1040. Needed for any carryforward or to confirm residency status.
- Social Security number and Ohio taxpayer ID. These must match the IT 1040 exactly.
- Federal employer identification number (FEIN) of the qualifying business. This is how the Department locates the company in its database.
A missing FEIN is the most common reason a return goes from auto-process to manual review. Manual review usually adds 8 to 12 weeks to processing.
Where to Get the Form and How to Access It
The official form lives on the Ohio Department of Taxation’s individual income tax forms page. Always download the current revision directly from the state, never from a third-party PDF aggregator, because aggregators often host outdated versions that omit the new ORC 5747.79 lines.
You can access the form three ways. First, as a fillable PDF on the Ohio tax forms portal. Second, embedded in approved tax software such as TurboTax, H&R Block, Drake, and Lacerte, which auto-populate it from your federal Schedule D. Third, through the OH|TAX eServices portal when you e-file your IT 1040.
If you prefer paper, the Department mails forms on request through its taxpayer services line. Allow 7–10 business days. Libraries and county auditor offices stock the IT 1040 but rarely stock Form 561, so do not rely on a walk-in pickup.
The form must be filed with the IT 1040, not separately. Mailing Form 561 alone to Columbus will not start any deduction process — it will sit in the unmatched-document queue. The Department’s system pairs Form 561 to the IT 1040 by Social Security number and tax year.
If you e-file, the software attaches Form 561 as a binary or XML schema. Confirm in the e-file summary that “IT-561” appears in the attached schedules list before you transmit. A return that prints the deduction on the IT 1040 but lacks the attached 561 is rejected at the ODT gateway.
Step-by-Step: How to Fill Out Ohio Form 561 Line by Line
The form is organized into a header block, Part I (qualifying business information), Part II (gain calculation), Part III (Ohio apportionment and deduction amount), and a signature/certification block. Work top to bottom. Skipping ahead causes math errors that flow into the IT 1040.
Header — Taxpayer Name
The header asks for the taxpayer’s full legal name as it appears on the IT 1040.
Enter the name in ALL CAPITAL LETTERS with the format LAST, FIRST, MIDDLE INITIAL. For a joint return, enter the primary filer’s name — the one whose SSN appears first on the IT 1040.
Example: LOPEZ, MARIA J for a filer named Maria J. Lopez.
A common edge case is the recently married filer who changed names mid-year. The name on Form 561 must match the name the Social Security Administration has on file as of the filing date, not the name on the brokerage 1099-B.
A common mistake is entering “Maria & Carlos Lopez” on a joint return. The Department’s matching system reads this as a single 90-character name string and fails to pair it to the IT 1040, which delays the refund.
A common misconception is that nicknames or shortened names are acceptable because the SSN is also on the form. They are not. The name field is a hard match, and a mismatch alone can hold the deduction.
Header — Social Security Number
This field asks for the primary taxpayer’s nine-digit SSN.
Write the SSN with dashes in the format XXX-XX-XXXX. On the fillable PDF, dashes auto-insert; on paper, write them.
Example: Maria writes 123-45-6789 in the SSN box.
If you are an ITIN holder rather than an SSN holder, enter the ITIN. Form 561 accepts both, but the ITIN must be active.
A common mistake is transposing two digits, especially the middle pair. The Department’s match fails silently and the deduction is removed without notice; you see it only when the refund arrives short.
A common misconception is that the SSN on Form 561 can differ from the IT 1040 if the spouse owned the stock. It cannot. If only the spouse held the interest, the spouse’s SSN must lead the IT 1040 and Form 561.
Header — Tax Year
This box asks which tax year the deduction belongs to.
Enter the four-digit year that matches the IT 1040, formatted YYYY.
Example: For a return filed in April 2026 for income earned in 2025, Maria writes 2025.
The edge case is a fiscal-year filer. Ohio individual income tax is calendar-year only, so enter the calendar year of the sale even if your federal pass-through entity uses a fiscal year.
A common mistake is entering the filing year (2026) instead of the income year (2025). This routes the form to the wrong processing batch and creates a duplicate-year flag.
A common misconception is that you can claim the deduction in the year you receive the cash, even if the gain was reported in an earlier year. The deduction follows the year the federal gain was recognized.
Part I, Line 1 — Name of Qualifying Ohio Business
This line asks for the legal name of the company whose stock or interest you sold.
Enter the company name exactly as it appears on the qualifying-business certification letter. Use the legal entity name, not the trade name or DBA.
Example: Carlos sold his stake in the parent company of a Cleveland software startup. He enters NORTHCOAST ANALYTICS INC even though the product was branded “ClevelandStack.”
The edge case involves successor entities. If the company merged or was acquired before your sale, enter the name of the entity at the time of sale and attach a one-page successor statement.
A common mistake is using the trade name. The Department searches its database by legal name and FEIN; a trade-name entry returns “no match” and the deduction is denied at first review.
A common misconception is that the company must still exist when you file. It does not — a wound-down company can still be qualifying as long as it met the test during your holding period.
Part I, Line 2 — Federal Employer Identification Number (FEIN)
This line asks for the company’s nine-digit FEIN.
Enter the FEIN with a dash in the format XX-XXXXXXX.
Example: Northcoast Analytics Inc.’s FEIN is 34-1234567, so Carlos enters that.
The edge case is a single-member LLC that uses the owner’s SSN federally. In that case, enter the LLC’s state-assigned FEIN, not the SSN.
A common mistake is leaving the field blank because “the company gave me a stock certificate without an EIN.” A blank FEIN is an automatic kickout to manual review.
A common misconception is that the FEIN is confidential. It is not — the qualifying business is required to share it with selling owners under ORC 5747.79.
Part I, Line 3 — Ohio Headquarters Address During Holding Period
This line asks where the company’s headquarters sat while you owned the interest.
Enter the street address, city, and ZIP. Use the primary headquarters; if the headquarters moved during your holding period, enter the address that applied for the longest time and attach a brief explanation.
Example: Carlos enters 1100 Superior Ave, Cleveland, OH 44114.
A common edge case is a fully remote company. The deduction requires an actual Ohio physical headquarters during the holding period; a registered-agent address alone does not qualify.
A common mistake is entering the company’s current address when the headquarters was elsewhere during the holding period. The Department cross-checks against Ohio Secretary of State business filings, and a mismatch flags the form.
A common misconception is that any Ohio office counts. It does not — the deduction requires the primary operational headquarters, not a branch.
Part I, Line 4 — Date Ownership Interest Was Acquired
This line asks when you bought, were granted, or otherwise acquired the interest.
Enter the date in MM/DD/YYYY format. If you acquired the interest in tranches, enter the earliest acquisition date and list the others on an attachment.
Example: Carlos was granted founder stock on June 12, 2018. He enters 06/12/2018.
The edge case is stock received through option exercise. Use the exercise date, not the original grant date, because the holding period for capital gain purposes starts at exercise.
A common mistake is using the date the company was incorporated. The Department wants your acquisition date.
A common misconception is that vesting dates count. They do not for restricted stock you elected to treat under IRC Section 83(b) — those start at grant.
Part I, Line 5 — Date Ownership Interest Was Sold
This line asks the date you closed the sale.
Enter the date in MM/DD/YYYY. Use the trade date, not the settlement date.
Example: Carlos closed on August 15, 2025. He enters 08/15/2025.
The edge case is an installment sale. Use the date of the first installment payment as the sale date, and indicate “installment” on the attachment line.
A common mistake is entering the wire-receipt date. The taxable event is the trade date, and using a later date can artificially shorten or lengthen the holding period on paper.
A common misconception is that escrow holdbacks delay the sale date. They do not — the sale closes when ownership transfers, regardless of holdback timing.
Part I, Line 6 — Holding Period Certification
This line asks you to certify that your continuous holding period meets the statutory minimum under ORC 5747.79.
Check the box marked Yes if the holding period is met. Enter the total holding period in years and months in the adjacent field.
Example: Carlos’s holding period is 7 years and 2 months, so he checks Yes and enters 7 yr 2 mo.
The edge case is a holding period interrupted by a tax-free reorganization. The reorganization tacking rules apply, and the combined period counts; attach a statement.
A common mistake is checking Yes when a portion of the interest was held for less than the minimum. You must split the gain into qualifying and non-qualifying portions and only the qualifying portion goes on this form.
A common misconception is that the holding period runs to the closing date even if you signed a sale agreement earlier. The clock stops at the trade date the agreement becomes binding.
Part II, Line 7 — Federal Gain on Sale (from Schedule D)
This line asks for the gross capital gain you reported federally.
Enter the gain as a positive number with no dollar sign, rounded to the nearest whole dollar. Pull the figure from the relevant line of federal Schedule D.
Example: Carlos’s federal long-term gain is $812,400. He enters 812400.
The edge case is a partially deferred Section 1045 rollover. Enter the recognized portion only, not the deferred portion.
A common mistake is entering net-of-fees proceeds. The line is gain, not proceeds — gain equals proceeds minus basis minus selling costs.
A common misconception is that you can use Ohio-source gain here. You cannot — Line 7 is the federal gain, and Ohio apportionment happens later in Part III.
Part II, Line 8 — Adjusted Cost Basis
This line asks for your basis in the interest at the time of sale.
Enter your basis as a whole-dollar number. Include original cost, plus any Section 83(b) inclusion amounts, additional capital contributions, and basis adjustments from prior K-1s.
Example: Carlos paid $0.001 per share for 1,000,000 founder shares plus made one $50,000 follow-on investment. His basis is 51000.
The edge case is gifted or inherited stock. Gifted stock uses carryover basis; inherited stock uses stepped-up basis as of the decedent’s date of death.
A common mistake is using the federal AMT basis instead of regular-tax basis. Ohio follows regular-tax basis.
A common misconception is that founders can use fair market value at incorporation as basis. They cannot — the basis is what they actually paid.
Part II, Line 9 — Qualifying Gain Subtotal
This line asks for the gain that potentially qualifies for the deduction before Ohio apportionment.
Subtract Line 8 from Line 7 if you did not already net them on Schedule D, or simply transfer Line 7 if it already represents net gain. Enter as a positive number.
Example: Carlos’s federal Schedule D already nets basis, so he transfers his Line 7 amount of 812400 to Line 9.
The edge case is a partial sale. If you sold only a portion of your interest, Line 9 reflects only the portion sold; the remaining basis stays with the unsold portion.
A common mistake is double-subtracting basis when Schedule D already netted it. This artificially lowers Line 9 and the deduction.
A common misconception is that depreciation recapture flows here. It does not — recapture is ordinary income and is not part of the capital gain deduction.
Part III, Line 10 — Ohio Apportionment Percentage
This line asks what percentage of the gain is attributable to Ohio.
Enter a percentage between 0.00% and 100.00% to two decimals. For a resident, this is 100.00%. For a nonresident or part-year resident, use the Ohio business activity percentage from the qualifying company’s apportionment workpapers.
Example: Carlos is an Ohio resident, so he enters 100.00.
The edge case is a part-year resident who became a resident mid-holding-period. Apportion only the post-residency portion of the gain.
A common mistake is a nonresident entering 100% because “the company is in Ohio.” Nonresidents must use the company’s apportionment factor, which can be far below 100%.
A common misconception is that this percentage equals the company’s Ohio sales factor. It is the full three-factor or single-sales-factor result the company actually used on its Ohio Commercial Activity Tax filings.
Part III, Line 11 — Ohio Qualifying Gain
This line asks for Line 9 multiplied by Line 10.
Multiply Line 9 by the decimal form of Line 10. Round to the nearest whole dollar.
Example: Carlos multiplies 812400 × 1.0000 and enters 812400.
The edge case is a result that exceeds the annual deduction cap. Enter the full computed number here; the cap applies on Line 12.
A common mistake is entering the percentage as a percent instead of a decimal in the math. Always convert (100.00% becomes 1.0000) before multiplying.
A common misconception is that you can round up. Round to the nearest dollar using standard rounding (0.50 rounds up).
Part III, Line 12 — Capital Gain Deduction
This line asks for the deduction amount that flows to the Ohio Schedule of Adjustments.
Enter the lesser of Line 11 or the statutory annual cap. Confirm the current cap on the Ohio Department of Taxation tax alerts page before filing.
Example: Carlos’s Line 11 is below the cap, so he enters 812400.
The edge case is a married couple filing jointly with both spouses qualifying. The cap applies per return, not per spouse.
A common mistake is also taking the same gain as a federal Section 1202 exclusion without adjusting Ohio. Ohio decouples in part — read the instructions carefully.
A common misconception is that any unused deduction carries forward. It does not under current law; unused amounts are lost.
Signature and Certification Block
This block asks the taxpayer (and spouse, if joint) to certify under penalty of perjury that the information is true.
Sign in blue or black ink. Date in MM/DD/YYYY. Both spouses sign on a joint return, even if only one held the interest.
Example: Carlos signs and dates 04/10/2026; his spouse Elena signs the same date.
The edge case is e-filing — the Ohio IT 1040 e-file signature covers Form 561 automatically; no separate digital signature is required.
A common mistake is one spouse signing on a joint return. The Department treats a single-signature joint 561 as incomplete and removes the deduction.
A common misconception is that the certification is a formality. It is sworn — false certification can support a fraud penalty under ORC 5747.15.

How to File the Completed Form
Form 561 must be filed with the Ohio IT 1040, never alone. Choose one of the channels below. Each has a different proof-of-filing requirement.
Online via OH|TAX eServices. File through the OH|TAX eServices portal. There is no fee. Payment of any balance due is by ACH debit, credit card (with a third-party processor fee around 2.5%), or e-check. Processing typically runs 2–3 weeks for refunds. Save the confirmation number — that is your proof of filing.
E-file through approved tax software. Use TurboTax, H&R Block, Drake, Lacerte, or another Ohio-approved e-file provider. Software fees vary. Payment options match OH|TAX. Refund processing is 2–3 weeks. The software’s electronic acknowledgment is your proof.
Paper mail. Print the IT 1040, attach Form 561, attach federal Schedule D and Form 8949, attach the qualifying-business certification, and mail to the address printed on the IT 1040 instructions. Refund returns and balance-due returns use different P.O. boxes — do not mix them. There is no filing fee. Pay any balance due by check payable to “Ohio Treasurer of State.” Processing is 8–12 weeks. Use USPS Certified Mail with return receipt as your proof.
Through a paid preparer. A licensed Ohio CPA or enrolled agent can file on your behalf. Preparer fees vary. The preparer’s signed authorization is your proof.
For amended returns, attach Form 561 to the Ohio IT 1040X and check the amended box. The same channels apply, except amended returns generally must be paper-filed unless your software supports state amendments.
What Happens After You File
After filing, the Department’s automated system pairs your Form 561 to your IT 1040 by SSN and tax year. If everything matches, the deduction posts and your refund or balance-due calculation reflects it.
Within 4–6 weeks you may receive a Request for Additional Information if any of these flags trigger: missing FEIN, address mismatch with the Ohio Secretary of State database, holding-period certification incomplete, or Line 11 exceeding the statutory cap. You have 30 days to respond. Missing the deadline removes the deduction.
If the Department disagrees with your position, it issues a Notice of Proposed Assessment under ORC 5747.13. You have 60 days to file a petition for reassessment with the Tax Commissioner. After that, appeals run to the Ohio Board of Tax Appeals and then to the courts.
If the deduction is allowed, keep your Form 561 and supporting documents for at least four years. The statute of limitations under ORC 5747.13 generally allows the Department to audit for four years from the filing date, longer in fraud cases.
Mistakes to Avoid When Filling Out the Form
- Wrong tax year in the header. Routes the form to the wrong batch and triggers a duplicate-year flag that delays the refund.
- Missing FEIN on Line 2. Causes automatic kickout to manual review and adds 8–12 weeks to processing.
- Trade name instead of legal name on Line 1. The database returns “no match” and the deduction is denied at first review.
- Using the current HQ address instead of the holding-period address. Mismatches against Secretary of State filings and flags the form for review.
- Entering net proceeds instead of gain on Line 7. Overstates the deduction and triggers a basis-mismatch notice.
- Using AMT basis instead of regular basis on Line 8. Misstates qualifying gain and produces a calculation error letter.
- Resident filer entering less than 100% on Line 10. Underclaims the deduction and the Department will not correct it for you.
- Nonresident entering 100% on Line 10. Overstates the deduction and triggers a proposed assessment.
- One spouse signing a joint Form 561. Treated as incomplete; the deduction is removed.
- Filing Form 561 without attaching federal Schedule D. No reconciliation possible; deduction denied.
- Claiming the deduction without the qualifying-business certification. Denied on first manual review.
- Forgetting to check the holding-period box on Line 6. Treated as failure to certify; deduction denied.
Do’s and Don’ts
Do’s:
- Do download the form fresh each year from the Ohio Department of Taxation forms page, because line numbers and caps change.
- Do request the qualifying-business certification letter before you sell, while the company is still cooperative.
- Do keep both the trade confirmation and the closing statement, because the Department may ask for either.
- Do reconcile Form 561 to your federal Schedule D line by line before signing.
- Do e-file when possible, because paper processing is 4× slower and paper-only forms get lost more often.
- Do keep a complete copy — including attachments — for at least four years.
Don’ts:
- Don’t mail Form 561 alone; it will sit unmatched indefinitely.
- Don’t estimate basis. The Department will ask for proof and an estimate fails.
- Don’t assume vesting equals acquisition. The acquisition rules differ for restricted stock.
- Don’t combine multiple sales on one Form 561. File a separate Form 561 for each qualifying business.
- Don’t sign the certification if any qualifying condition is unclear; ask a CPA first.
- Don’t ignore a Request for Additional Information. The 30-day clock is firm.
Pros and Cons of Filing on Your Own vs. With Help
Pros of filing on your own:
- Lower cost, because you avoid preparer fees that often run $400–$1,500 for returns with Form 561.
- Speed of control, since you can file the moment your documents are ready.
- Direct understanding of the deduction, which helps in future years.
- Privacy of financial information, which some founders prefer.
- Software does the math, so the calculation risk is lower than it once was.
Cons of filing on your own:
- Higher denial risk, because pro se filers miss the qualifying-business certification more often.
- No representation if the Department issues a Notice of Proposed Assessment.
- No second set of eyes on basis, which is the #1 audit issue.
- Time investment of 4–10 hours including document gathering.
- No appeal strategy beyond what you can build yourself, which weakens Board of Tax Appeals cases.
Pro Se vs. CPA-Prepared Filing
| Factor | What It Means |
|---|---|
| Cost | Pro se: software-only fee. CPA: $400–$1,500 for the 561 add-on. |
| Audit defense | Pro se: you defend yourself. CPA: representation included by most firms. |
| Typical denial rate | Pro se: roughly 1 in 5 first-year filers. CPA-prepared: far lower per Department alerts. |
| Time required | Pro se: 4–10 hours. CPA: 1–2 hours of your time. |
| Best fit | Pro se: simple resident filer with clean basis. CPA: nonresidents, K-1s, partial-tranche, or installment sales. |
FAQs
Is Ohio Form 561 the same as federal Section 1202?
No. Form 561 is Ohio’s separate capital gain deduction under ORC 5747.79. It can stack with federal Section 1202 in some cases but uses different qualification rules.
Do I file Form 561 if I had a capital loss?
No. The form is only for taxpayers claiming a capital gain deduction. A loss is reported on Schedule D federally and flows through to Ohio without Form 561.
Can a trust or estate file Form 561?
No. Trusts and estates use the parallel deduction on the Ohio IT 1041 and a different schedule, not Form 561.
Do I write my maiden name or married name in the header?
No to whichever doesn’t match SSA records. Use the name the Social Security Administration has on file as of the filing date.
If only my spouse owned the stock, whose SSN goes in the header?
No to listing yours first. The owner-spouse’s SSN must lead the IT 1040 and Form 561.
Do I enter the trade date or settlement date on Line 5?
Yes, the trade date. The taxable event is the trade date, not the date of wire receipt or settlement.
Should I enter Line 10 as 100.00% if I’m an Ohio resident?
Yes. Residents apportion 100% of qualifying gain to Ohio. Nonresidents use the company’s apportionment factor.
Can I carry forward unused deduction to next year?
No. Under current Ohio law, unused capital gain deduction does not carry forward; the unused amount is lost.
Do I need to attach the qualifying-business certification?
Yes. Without it, the deduction is denied on review even if every line is correct.
Can I file Form 561 by itself if I already filed my IT 1040?
No. You must file an Ohio IT 1040X amended return and attach Form 561 to it.
Does the holding period include time before I became an Ohio resident?
Yes for the holding-period test, but no for apportionment — only the post-residency portion may apportion at 100%.
Are stock options counted from grant or exercise?
No to grant. The holding period for capital gain purposes starts at exercise, except for Section 83(b) elections, which start at grant.
What happens if I sign but my spouse doesn’t on a joint return?
No deduction. The Department treats a single-signature joint Form 561 as incomplete and removes the deduction entirely.
Can I claim Form 561 if the company was acquired and no longer exists?
Yes, as long as the company met the qualifying tests during your holding period. Attach a successor-entity statement.
Does Form 561 affect my school district income tax?
No. The capital gain deduction is an Ohio AGI adjustment, but school district taxable income follows separate rules — check the SD-100 instructions.
