Ohio Homestead Exemption Application Guide: How to Apply, Forms, Deadlines & Property Tax Savings
If you are searching how to apply for homestead exemption in Ohio, the key rule is simple: file with the county auditor in the Ohio county where your home is located. Ohio does not use one universal public homeowner portal for every county; some county auditors offer online filing, while others use mail, email, walk-in filing, or downloadable DTE forms.
For most senior, disability and surviving-spouse applicants, the starting form is DTE 105A. Disabled applicants usually add DTE 105E. Qualified 100% disabled veterans generally use DTE 105I, and surviving spouses of public service officers killed in the line of duty use DTE 105K.
How Do You Apply for Homestead Exemption in Ohio?
Apply through your Ohio county auditor. Complete the correct homestead form, attach income, disability, veteran, survivor, ownership, or trust documents when required, and submit the application by the county’s deadline. Online filing is county-specific, so the correct portal depends on where the property is physically located.
Step 1: Use the County Auditor
Homestead exemption is not filed with the Ohio Department of Taxation, your mortgage company, or the county treasurer. The county auditor reviews eligibility and posts the reduction to the property or manufactured-home record.
Step 2: Use the Correct DTE Form
DTE 105A is the common application for senior citizens, permanently and totally disabled persons, and eligible surviving spouses. Veterans and public-service-officer survivor categories use different forms.
Step 3: Check Online Filing
Some counties provide SmartFile or online forms, while others require mail, email, original signature, or in-person filing. Always follow your own county auditor’s instructions.
Who Qualifies Before Applying?
Ohio homestead exemption is not a general exemption for every homeowner. It is mainly for qualifying older homeowners, permanently and totally disabled homeowners, eligible surviving spouses, certain 100% disabled veterans, and certain public-safety surviving spouses.
Senior Homeowners
You may qualify if you are age 65 or will turn 65 during the year for which you apply, own the home, occupy it as your principal residence, and meet the applicable income rule unless you are grandfathered.
Permanently and Totally Disabled
A disabled applicant must be permanently and totally disabled as of January 1 of the year requested. DTE 105E or another accepted state/federal disability certification is usually required.
Eligible Surviving Spouse
A surviving spouse may qualify if the deceased spouse received homestead for age or disability in the year of death and the surviving spouse was at least 59 on the date of death, while meeting all other requirements.
| Applicant Type | Basic Ohio Rule | Application Form | Income Rule |
|---|---|---|---|
| Senior citizen | Age 65 or older during the year requested, own and occupy the home as principal residence. | DTE 105A | New applicants generally must meet the indexed income threshold unless grandfathered. |
| Permanently and totally disabled person | Disabled as of January 1 and unable to work under Ohio’s permanent-total-disability rule. | DTE 105A + DTE 105E or accepted disability certification | Income threshold generally applies unless grandfathered. |
| Surviving spouse of senior/disabled homestead recipient | Spouse received homestead in year of death; surviving spouse was at least 59 on date of death. | DTE 105A | Income rule can apply depending on status and grandfathering. |
| 100% disabled veteran | Honorably discharged veteran with 100% service-connected disability rating or 100% compensation based on individual unemployability. | DTE 105I | No standard senior/disabled income test for this enhanced category. |
| Surviving spouse of public service officer killed in line of duty | Eligible unremarried surviving spouse under Ohio public-service-officer rules. | DTE 105K | No standard senior/disabled income test for this enhanced category. |
How to Apply for Ohio Homestead Exemption Step by Step
This workflow works whether your county offers online filing, a fillable PDF, email submission, mail filing, or walk-in filing. County details vary, but the decision-maker is still the county auditor.
Confirm the County Where the Home Is Physically Located
Start with the property location, not only the mailing city or ZIP code. Cities such as Columbus, Cleveland, Cincinnati, Dayton, Toledo, Akron, Youngstown, Dublin, Westerville, Loveland and Springboro can create county-boundary confusion.
Find Your County Auditor
Use the County Auditors’ Association of Ohio directory or your county’s official website. Look for the Auditor, Real Estate, Homestead Exemption, Tax Reduction, Forms, or Property Search section.
Search Your Parcel or Manufactured-Home Record
Find the parcel number, taxing district, registration number, property address, owner name, market value, current tax district and any existing homestead or owner-occupancy credit.
Choose the Correct Application Form
Use DTE 105A for senior, disabled-person and eligible surviving-spouse applications. Use DTE 105I for 100% disabled veterans and surviving spouses. Use DTE 105K for surviving spouses of public service officers killed in the line of duty.
Attach Proof Before You Submit
Prepare proof of age, owner-occupancy, disability certification, VA award letter, DD214, income records, no-filing income addendum, trust pages, life-estate document, land contract, cooperative proof, or other ownership documents if applicable.
Submit Online if Your County Offers It
Some counties offer online filing. Examples include Montgomery County’s online homestead application, Lake County SmartFile, and Franklin County electronic filing for certain applicants. Save confirmation numbers and uploaded-document receipts.
Use Mail, Email or Walk-In Filing if Required
If your county requires a wet signature or does not accept online filing for your category, print the form and follow that county’s mailing, email, drop-box, or in-person instructions. Keep a copy of everything you submit.
File by the Correct Deadline
For real property, file by December 31 of the year for which the exemption is sought. For manufactured or mobile homes, county guidance often treats the application year differently because manufactured-home taxes are paid currently; file early and confirm the correct tax year with the auditor.
Watch for Approval, Denial or Income Verification
County auditors may verify Ohio modified adjusted gross income through Ohio Department of Taxation records. Applications submitted before your state income tax return is processed may not be decided until income verification is available.
Check the Next Tax Bill
If approved as a current applicant, the credit generally appears on the later tax bill for that tax year’s collection cycle. If approved late for a prior year, the credit may be refunded or applied depending on county tax status and payment history.
Which Ohio Homestead Form Should You Use?
Ohio homestead applications are form-driven. The form number matters because each category has different proof requirements, signatures, income rules and county processing steps.
| Form | Use This Form For | Common Attachments | Filing Tip |
|---|---|---|---|
| DTE 105A | Senior citizens, permanently and totally disabled persons, and eligible surviving spouses. | Proof of age, Ohio income information, spouse information, parcel/registration number, ownership proof if requested. | This is the standard starting point for most non-veteran applicants. |
| DTE 105E | Certificate of Disability for the Homestead Exemption. | Physician, psychologist, or accepted state/federal disability certification. | Attach it to DTE 105A when applying as permanently and totally disabled. |
| DTE 105H | Income addendum when neither applicant nor spouse files federal or Ohio income tax returns. | W-2, 1099, pension, Social Security, interest, dividend, retirement, deduction and other income proof. | Use when the county cannot verify MAGI through tax returns. |
| DTE 105G | Grandfathered or continuing homestead status transfer support. | Prior Ohio homestead information and residence-change details. | Important when a pre-2014 Ohio homestead claimant moves to another Ohio residence. |
| DTE 105I | 100% disabled veterans and eligible surviving spouses. | DD214, VA award letter showing 100% rating or 100% compensation based on individual unemployability. | This is an enhanced category and should not be confused with regular disabled-person homestead. |
| DTE 105K | Surviving spouse of a public service officer killed in the line of duty. | Confirmation from the appropriate pension fund, department, agency, employer, or other official source. | Ask the county auditor what documentation is needed before the deadline. |
| DTE 106B | Complaint after homestead or owner-occupancy reduction denial or incorrect reduction. | Denial notice, parcel information, eligibility documents, and supporting proof. | Filing windows are short; read the denial notice immediately. |
| DTE 101 | Homestead conveyance statement when a qualifying homestead property transfers. | Transfer documents and conveyance information. | Used in sale/transfer workflows; it does not replace the new owner’s application. |
Ohio Homestead Exemption Documents to Prepare
The best way to avoid delay is to gather the documents before opening the county online portal or mailing the application.
Property and Ownership Proof
- County, taxing district, parcel number or manufactured-home registration number.
- Property address and mailing address.
- Owner name as shown on county records.
- Deed, land contract, life estate, mortgage, trust or cooperative proof when requested.
Income Proof
- Ohio IT 1040 information for the prior income year.
- Ohio Schedule A business-income information if applicable.
- Federal return if no Ohio return was filed.
- DTE 105H and supporting income records if no federal or Ohio return was filed.
Special Category Proof
- Proof of age for senior applications.
- DTE 105E or accepted disability certification.
- DD214 and VA award letter for 100% disabled veteran applications.
- Death certificate, marriage proof, survivor proof or public-service-officer confirmation when applicable.
Ohio Homestead Application Deadlines and Timing
Ohio deadlines can feel confusing because real property taxes and manufactured/mobile home taxes are handled differently. The safest approach is to contact the county auditor early in the filing year and not wait until the tax bill is due.
| Situation | Timing Rule | Practical Action |
|---|---|---|
| Real property current application | File with the county auditor on or before December 31 of the year for which the reduction is sought. | Apply after you confirm age/disability/income status and before Dec. 31. |
| Manufactured or mobile home | Because manufactured-home taxes are paid currently, county guidance often requires filing in the year before the benefit year. | Ask the county auditor which tax year the application will affect before submitting. |
| Late application for prior year | DTE 105A allows a late application for the missed prior year only when filing for the same property and the facts qualify. | Check both current and late boxes only when the county form and your facts support it. |
| Income verification pending | Applications submitted before Ohio income tax processing may not be decided until county auditor income verification is complete. | Do not assume silence means approval; follow up with the auditor if the record does not update. |
| Denied application | The denial notice should explain the reason and appeal/complaint route. | Ask about DTE 106B and the county Board of Revision filing window immediately. |
| Moved to a new Ohio home | The exemption does not automatically move with you. | Reapply at the new county/address and use DTE 105G if grandfathered status must be documented. |
How Much Does Ohio Homestead Exemption Save?
Ohio homestead savings are not the same as the exemption amount. The exemption shields a portion of the auditor’s appraised market value from taxation, and the tax savings depend on local effective tax rates, school district, city, township, levy structure and other reductions.
Standard Homestead
The standard homestead exemption shields a fixed amount of the home’s market value from taxation for qualifying seniors, permanently and totally disabled homeowners and eligible surviving spouses. The amount is indexed and county auditors should verify the active year.
Enhanced Homestead
The enhanced exemption for qualifying 100% disabled veterans and qualifying surviving spouses of public service officers killed in the line of duty shields a larger amount of market value from taxation.
Assessment Concept
Ohio real property is assessed at a percentage of market value. A simplified estimate often applies the exempt market value to the assessment rate and effective mills, but the county auditor’s calculation controls.
Ohio Homestead Exemption Savings Estimator
This educational calculator estimates the tax impact of shielding market value. It does not calculate exact county rollbacks, special assessments, voted levy treatment, local-option relief, refunds, penalties, or final bills.
Formula used: market-value shield × 35% assessment factor × effective mills ÷ 1,000. Ask your county auditor or treasurer for the official tax district calculation.
Can You Apply for Ohio Homestead Exemption Online?
In some counties, yes. Ohio homestead filing is local, so the online option depends on the county auditor. A statewide DTE form exists, but that does not mean every county uses the same online system.
| County Example | Online / Filing Reality | Best User Action |
|---|---|---|
| Franklin County | Franklin County Auditor provides homestead forms and indicates senior/disabled applicants may file electronically in some workflows. | Use the Franklin Auditor homestead page, property record and official form center. |
| Montgomery County | Montgomery County provides a homestead exemption online application route. | Use the Montgomery County Auditor online form or PDF route listed by the county. |
| Lake County | Lake County provides a SmartFile paperless filing option and mail/walk-in alternatives. | Use Lake County Auditor SmartFile when available, or submit the county form by mail or in person. |
| Cuyahoga County | Cuyahoga County Fiscal Office publishes homestead forms and category guidance. | Use the Fiscal Office homestead page and confirm whether online, mail or office submission is required for your category. |
| Other Ohio counties | Online filing varies. Some counties use downloadable forms only; some require original signatures; some offer county portals. | Start with the CAAO county auditor directory, then follow the official county auditor instructions. |

Common Ohio Homestead Application Mistakes
These mistakes cause many denied, delayed, duplicated or missing homestead reductions.
Filing With the Treasurer Instead of the Auditor
The treasurer collects taxes. The county auditor processes homestead eligibility and reduction status. Start with the auditor when applying or fixing a missing exemption.
Missing the Dec. 31 Deadline
The deadline is not the same as the tax-bill due date. File with the county auditor by the applicable Dec. 31 deadline or ask about late application rules immediately.
Using the Wrong Income Year
The income test uses the owner and spouse’s prior-year Ohio modified adjusted gross income. For many 2026 applications, that means 2025 income.
Not Reapplying After a Move
Ohio homestead does not automatically transfer to a new home. Reapply at the new address and document grandfathered status when applicable.
Missing Disability or Veteran Proof
DTE 105E, VA award letters, DD214 records and survivor confirmations are category-specific. Submitting DTE 105A alone may not be enough.
Applying Through an LLC or Business Entity
Individual ownership, trust rights, life estate, land contract and similar arrangements may qualify, but LLC, partnership and corporate ownership generally do not qualify for individual homestead.
What Should You Do Next?
| Your Situation | Best Next Step | Correct Office |
|---|---|---|
| You are 65 or will turn 65 during the application year. | Find your county auditor, complete DTE 105A or county online application, and prepare prior-year income information. | County Auditor |
| You are permanently and totally disabled. | Complete DTE 105A and attach DTE 105E or an accepted disability certification. | County Auditor |
| You are a 100% disabled veteran. | Use DTE 105I and attach DD214 plus VA documentation showing the qualifying rating or compensation status. | County Auditor |
| You are a surviving spouse. | Determine whether DTE 105A, DTE 105I or DTE 105K applies based on the deceased spouse’s status and your survivor category. | County Auditor |
| You moved to a new Ohio home. | Reapply at the new address. Use DTE 105G if you need to document grandfathered/continuing status. | County Auditor |
| Your county has no online portal. | Download the official county form, sign it as required, and submit by mail, email, drop box or in person according to county instructions. | County Auditor |
| Your exemption is approved but the bill looks wrong. | Compare the auditor record with the treasurer bill. Use the treasurer only after the auditor record shows the correct reduction. | Treasurer after Auditor review |
| Your application was denied. | Read the denial notice and ask about DTE 106B, Board of Revision review and the deadline to challenge the denial. | County Auditor / Board of Revision |
Ohio Homestead Exemption Application FAQs
Where do I apply for homestead exemption in Ohio?
Apply with the county auditor in the Ohio county where your home is located. The Ohio Department of Taxation provides state forms and rules, but the county auditor processes the application and posts the reduction to the property record.
Is there one statewide Ohio homestead exemption online application?
No. Ohio homestead filing is handled county by county. Some county auditors offer online filing, such as SmartFile or county web forms, while others require mail, email, original signature or in-person filing.
What form do I use to apply for Ohio homestead exemption?
Most senior, permanently and totally disabled, and eligible surviving-spouse applicants use DTE 105A. Disabled applicants usually attach DTE 105E. 100% disabled veterans generally use DTE 105I, and surviving spouses of public service officers killed in the line of duty use DTE 105K.
What is the Ohio homestead exemption deadline?
For real property, the application is generally filed with the county auditor on or before December 31 of the year for which the reduction is sought. Manufactured and mobile home timing can differ because those taxes are paid currently, so confirm the benefit year with the county auditor.
What is the Ohio homestead exemption income limit for 2026 applications?
For many new senior and disabled applicants applying in 2026, the income threshold is $41,000 using the owner and spouse’s 2025 Ohio modified adjusted gross income. Grandfathered applicants and enhanced veteran or public-service-officer survivor categories may be treated differently.
How much value does Ohio homestead exemption shield?
The standard amount currently used in many Ohio 2026 filing discussions is $29,000 of auditor appraised market value. The enhanced amount for qualifying 100% disabled veterans and certain public-service-officer surviving spouses is $58,000. These amounts are indexed, so verify the active tax year with the county auditor.
Do I have to reapply every year for Ohio homestead exemption?
Usually no, if you continue to qualify and the property remains your principal residence. However, you must notify the county auditor or return the continuing application if ownership, occupancy, income, disability status, or eligibility changes.
Does Ohio homestead exemption transfer when I move?
No. If you move to a new Ohio home, you must apply again at the new address. If you have grandfathered status from an earlier Ohio homestead, ask the auditor whether DTE 105G is needed.
What if my Ohio homestead application is denied?
Read the denial notice immediately. You may be able to file DTE 106B, Homestead Exemption and Owner-Occupancy Reduction Complaint, with the county Board of Revision or follow the appeal route listed by the county.
Who should I call if my Ohio homestead exemption is missing from the tax bill?
First contact the county auditor to confirm whether the homestead exemption was approved and posted to the property record. If the auditor record is correct but the bill or payment record still looks wrong, then contact the county treasurer.
