Ohio Home Daycare Tax Deductions — Provider Tax Guide

Home daycare providers often leave thousands of dollars on the table at tax time because they do not understand how the Time-Space Percentage works, or they assume that because they operate from their residence, household expenses are not deductible. The opposite is true — home-based child care is one of the most tax-advantaged small business models available, precisely because so much of your home serves a dual business purpose.

The Time-Space Percentage

The Time-Space Percentage is the core calculation that determines what share of your home expenses are deductible as business costs. It combines two factors:

Time Percentage: The number of hours your home is used for business divided by the total hours in the year (8,760). Business hours include not just the hours children are present, but also time spent on business activities while children are not there — cleaning and sanitizing, preparing meals, planning curriculum, maintaining records, completing professional development, and setting up or restoring the space.

A provider who offers care Monday through Friday, 7 AM to 5 PM (10 hours per day, 260 days per year) has 2,600 direct care hours. Add 1–2 hours of daily business activity outside care hours (cleaning, meal prep, record keeping) and weekend preparation time, and the total can reach 3,000–3,500 hours. That puts the Time Percentage at 34–40%.

Space Percentage: The square footage of your home used regularly for business divided by total square footage. Rooms used exclusively for daycare (a dedicated playroom, nap room) count at 100%. Rooms used for both personal and business purposes (living room, kitchen, dining area, bathrooms) count proportionally. Most home daycare providers find that 60–80% of their home's square footage serves a business function during operating hours.

Multiply the two percentages together and you get your Time-Space Percentage — typically 25–35% for most full-time home daycare providers. This percentage is applied to your shared home expenses to determine the deductible business portion.

What You Can Deduct

Home expenses subject to the Time-Space Percentage include:

• Mortgage interest or rent — the largest deduction for most providers
• Property taxes (or the renter's equivalent passed through in rent)
• Homeowners or renters insurance — the personal policy portion; your commercial daycare liability policy is 100% deductible as a business expense
• Utilities — electricity, gas, water, trash, internet
• Home repairs and maintenance — roof repairs, HVAC maintenance, painting, plumbing work
• Depreciation — your home (not the land) can be depreciated over its useful life, creating a non-cash deduction

Expenses that are generally direct business expenses (rather than subject to the Time-Space Percentage) include:

• Daycare liability insurance — your commercial policy premium
• Toys, books, and educational materials used exclusively for the program
• Cribs, cots, high chairs, and child-specific furniture
• Food served to children (or CACFP-reimbursed food, net of reimbursements)
• Professional development — training fees, conference costs, CPR certification renewal
• Office supplies and software used for the business
• Advertising and marketing costs
• Business phone and internet — the documented business-use portion
• Cleaning supplies used for daycare sanitation
• Background check fees (BCI/FBI fingerprinting costs for you, staff, and household members)
• Licensing fees — the $25 application fee
• LLC registration — the $99 Ohio Secretary of State fee

Self-Employment Tax

As a home daycare provider, you are self-employed. That generally means paying both the employer and employee portions of Social Security and Medicare taxes. The commonly cited combined rate is 15.3% (12.4% Social Security + 2.9% Medicare) before applicable wage-base and additional-Medicare rules. Half of this self-employment tax is deductible as an adjustment to income on your personal return.

Estimated federal and Ohio tax payments may be required during the year; the thresholds and safe-harbor rules differ, so confirm them for the current tax year. Underpaying estimated taxes can trigger penalties, so setting aside 25–30% of net income for taxes throughout the year prevents a painful April surprise.

Record Keeping That Survives an Audit

The IRS expects home daycare providers to maintain documentation that supports every deduction claimed. The records that matter:

Time log: Track the hours your home is used for daycare — when children arrive and leave, and the additional business hours spent on cleaning, prep, and administration. A simple daily log is sufficient. If you participate in PFCC and use KinderConnect for attendance, those records serve as part of your time documentation.

Expense receipts: Keep receipts for all business purchases. For shared home expenses (utilities, mortgage), your monthly statements are sufficient. For 100% business expenses (toys, supplies, insurance), retain individual receipts or credit card statements.

Mileage log: If you transport children or drive for business purposes (supply runs, training events, meetings), track mileage with dates and purposes. The IRS standard mileage rate for 2026 applies to business miles driven.

Depreciation records: If you claim home depreciation, maintain records of your home's purchase price, improvements, and the depreciation method used. This is worth setting up correctly from year one — a CPA experienced with home daycare businesses can ensure the depreciation calculation is accurate and defensible.

State-Level Considerations

Ohio income tax applies to your net self-employment income. Ohio offers a small business income deduction that may reduce your state tax liability — up to $250,000 of qualifying business income may be deducted for most filers ($125,000 per spouse filing separately). Your CPA can determine whether your daycare income qualifies for this deduction based on the current year's rules.

Ohio's Commercial Activity Tax (CAT) generally excludes businesses with $6 million or less of taxable gross receipts for 2025 and later tax years. Most home daycare providers fall below this threshold, but confirm current registration rules if you operate a Type A program at full capacity with premium rates.

Getting Professional Help

The Time-Space Percentage calculation is straightforward in concept but involves enough moving parts that a CPA who specializes in home daycare businesses is worth the investment. They can help you calculate the optimal Time-Space Percentage, identify deductions you are missing, set up quarterly estimated payments correctly, and ensure your depreciation records are audit-ready.

Tom Copeland's resources on family child care taxation (available through the National Association for Family Child Care) are widely regarded as the definitive reference for home daycare tax planning. Your local CCR&R may also offer free tax workshops during the first quarter of the year.
