Depreciating Your Home for Daycare: Form 8829, and What Happens When You Sell

If you've already worked out your time-space percentage — the number that tells you what share of your mortgage interest, utilities, and insurance you can deduct as a business expense — there's one more line on Form 8829 that trips up more providers than any other: depreciation. It's not a bill you paid this year, so it doesn't feel like a real expense, and the idea of "depreciating your house" sounds like something that only applies to landlords. It applies to you too, and skipping it isn't the free pass it looks like. This article assumes you already have your time-space percentage in hand; if you don't, start with the article linked above before coming back here.

Why depreciation is different from every other line on Form 8829

Everything else on Form 8829 — mortgage interest, utilities, homeowners insurance, repairs — is money that actually left your bank account this year, multiplied by your business-use percentage. Depreciation isn't a cash expense at all. It's the IRS's way of letting you deduct a slice of your home's value each year, spread out over a set recovery period, because the business portion of your home is treated as a business asset that wears out over time — at least for tax purposes, whether or not it's actually losing value.

That's also exactly why it's easy to skip: there's no receipt, no bill, nothing that lands in your inbox reminding you it exists. But it's a deduction you're leaving on the table every year you don't claim it, and — more importantly, as the recapture section below explains — skipping it doesn't protect you from anything down the road.

The mechanics: 39-year straight-line, not the schedule you'd guess

Per IRS Publication 587, when you begin using part of your home for business — daycare included — the business portion is depreciated as nonresidential real property under MACRS, using the straight-line method over 39 years. That's a longer, flatter schedule than the 27.5 years used for residential rental property, and it means the deduction is spread thin: a consistent, modest amount each year rather than a front-loaded write-off.

To calculate the dollar amount, you need your depreciable basis — and this is where the math has a specific order of operations:

1. Find the smaller of two numbers, both excluding the value of the land: your home's adjusted basis (generally what you paid for it, plus the cost of any improvements) on the date you started using it for daycare, or its fair market value on that same date.
2. Multiply that number by your business-use percentage — for a daycare provider, that's your time-space percentage, the same one you already calculated for your other home-expense deductions.
3. The result is your depreciable basis. Form 8829's instructions (and IRS Publication 946) provide the percentage table you apply to that basis for the first partial year and each year after, based on the month you started using your home for business.

Land is never depreciated, full stop. If your property tax statement or purchase documents don't already break out a land value separately from the structure, you'll need a reasonable way to estimate it — many providers use the land/building split from their county property tax assessment as a starting point, since it's already a documented, third-party figure.

Where this fits with your other daycare tax records

Depreciation isn't a standalone project — it's one line in the larger system you should already be running for every other deductible expense. If you haven't set up that broader system yet, our guide to tracking home daycare expenses all year covers the categories and the monthly habit that keeps tax time from turning into a shoebox of receipts; depreciation just slots in alongside everything else once a year, using the basis figure above.

This article covers depreciating the home itself. Equipment and personal property — a commercial fridge, outdoor play equipment, a laptop — run on a different set of rules entirely, sometimes deductible immediately rather than depreciated; see our Section 179 equipment deduction guide for that separate question.

The one piece of documentation depreciation specifically requires that other categories don't: a permanent record of your home's basis, the date business use began, and the depreciation claimed in every subsequent year — because you'll need all of it again, potentially decades later, when you sell. That's a different retention question than "how long do I keep this year's receipts," and it's worth reading alongside our record retention schedule, since the depreciation paper trail needs to outlive most of your other daycare records by design.

If you're still in the early planning stages of your daycare and haven't started using your home for business yet, the date you begin matters here — it's the date your depreciable basis gets locked in. Our guide to home daycare startup costs covers the bigger financial picture of getting a daycare off the ground; this article picks up specifically at the moment your home itself enters the business-use calculation.

What happens when you sell the house

This is the part that changes the calculus for a lot of providers, and it's worth understanding well before a sale is actually on the table.

When you sell a home you've used for business, the portion of your gain attributable to depreciation you claimed (or, critically, that you could have claimed) on the business-use part isn't eligible for the usual home-sale gain exclusion under Section 121 — the rule that lets most homeowners exclude a large chunk of gain on the sale of a primary residence. Gain attributable to depreciation taken after May 6, 1997, gets taxed separately as unrecaptured Section 1250 gain, subject to a maximum federal rate of 25%, reported through Form 4797. The rest of your gain on the home can still potentially qualify for the regular exclusion — it's specifically the depreciation-related slice that's carved out.

Here's the detail that surprises people: the IRS calculates this recapture based on depreciation "allowed or allowable" — meaning it applies whether or not you actually claimed the deduction every year. If you skipped depreciation on purpose, thinking you'd avoid this bill later, the IRS treats your basis as if you'd claimed it anyway when you sell. You lose the deduction you were entitled to during the years you owned the home, and you still face the same recapture math at the end. There's no version of this where skipping depreciation protects you — it only costs you the deduction now, for no benefit later.

That said, exactly how much of your home's eventual sale gain will be affected, and how it interacts with your specific basis, improvements, and years of business use, is genuinely complex enough that this is a good spot to bring in a tax professional before you file the year you claim it and again before you sell — this article describes the mechanism, not a substitute for that conversation.

If you're weighing an energy-efficient upgrade — new windows, insulation, a heat pump — while part of your home is a registered daycare, that has its own separate wrinkle on top of everything above: see our guide on home energy tax credits when part of your house is a daycare.

Where DaycareFlow fits

DaycareFlow doesn't calculate depreciation, prepare Form 8829, or track your home's basis — that's tax-return territory, not attendance-and-billing territory, and it genuinely deserves a tax preparer's attention rather than software guessing at it. What DaycareFlow does keep is the day-to-day business record that a preparer will ask for anyway: your active children roster, your billing history, and a dated attendance record, all in one place instead of scattered across a notebook and three payment apps.

Frequently asked questions

Do I have to depreciate my home if I run a daycare in it?

Depreciation on the business-use part of your home is a deduction you're entitled to claim, not usually optional in a way that helps you — and as the recapture section above explains, skipping it doesn't avoid the future tax consequence anyway, since recapture is calculated on depreciation "allowed or allowable" whether you claimed it or not. Most providers are better off claiming it and getting the current-year deduction.

How many years do I depreciate my home for daycare business use?

The business-use portion of your home is depreciated as nonresidential real property under MACRS, using the straight-line method over 39 years, per IRS Publication 587 — a longer and flatter schedule than the 27.5 years used for residential rental property.

What happens to depreciation when I sell my house?

Gain attributable to depreciation you claimed (or could have claimed) after May 6, 1997 is taxed as unrecaptured Section 1250 gain, at a federal rate of up to 25%, and generally can't be sheltered by the usual home-sale gain exclusion. This is a genuinely complex area worth reviewing with a tax professional before you sell.

Can I skip depreciation on purpose to avoid paying it back later?

No — and doing so doesn't help you. The IRS calculates recapture based on depreciation "allowed or allowable," meaning the same recapture math applies whether or not you actually claimed the deduction each year. Skipping it only costs you the current-year deduction with no offsetting benefit later.

Does depreciation apply to the land my house sits on?

No. Land is never depreciated for tax purposes — only the structure (the building itself). You'll need to separate your home's value from its land value, often using the split shown on your county property tax assessment, before applying your time-space percentage to figure the depreciable basis.
