Lands on Schedule C, line 30 — Expenses for business use of your home — the line both methods end at
If you rent a separate premises for the daycare, this article is not for you. This is about deducting part of the home you live in, and nothing here applies to a leased nursery — that rent is a straightforward business expense.
The simplified option is sold on a sentence everyone can follow: five dollars a square foot, up to three hundred feet, no receipts, one line.
For most home businesses that is a fair trade. For a daycare it is two reductions stacked on a business that happens to use most of the house, and the result is not close to what the same house produces the other way.
The short answer
| Simplified rate | $5 per square foot |
|---|---|
| Area allowed | Capped at 300 square feet |
| Ceiling before any daycare adjustment | $1,500 |
| The daycare adjustment | The $5 rate is multiplied by your hours fraction |
| Typical hours fraction | About 31% (2,750 of 8,760 hours) |
| What that leaves | About $471 |
| The same house, actual expenses | $5,086 in the example below |
| The one thing simplified buys you | No depreciation, so none to add back on sale |
| Can you switch each year? | Yes — it is not a change of accounting method |
The rate does not survive the daycare rule
Publication 587 sets the method out:
"$5, the prescribed rate, by the area of your home used for a qualified business use. The area you use to figure your deduction is limited to 300 square feet."
That is the version that circulates. Here is the paragraph that follows it for providers like you:
"If you do not use the area of your home exclusively for daycare, you must reduce the prescribed rate (maximum $5 per square foot) before figuring your deduction. The reduced rate will equal the prescribed rate times a fraction."
The numerator of that fraction is the hours the space was used for daycare during the year. The denominator is the total hours in the year — 8,760 for a full year.
So the daycare exception that lets you deduct a living room your family also uses does not come free on this method either. It comes with the same hours fraction the full method uses, applied to the rate instead of to the expenses.
The arithmetic, on one house
A provider open 11 hours a day, 250 days a year. Home of 2,000 square feet, of which 1,800 is used regularly for daycare. Total home expenses for the year — utilities, repairs and depreciation on the house — of $18,000.
The hours fraction, used by both methods:
| Hours used for daycare | 11 × 250 = 2,750 |
|---|---|
| Total hours in the year | 8,760 |
| Fraction | 2,750 ÷ 8,760 = 31.39% |
Simplified option:
| Prescribed rate | $5.00 |
|---|---|
| × hours fraction | × 31.39% |
| Reduced rate | $1.57 per square foot |
| Area — actual 1,800, capped at | 300 sq ft |
| Deduction | $471 |
Actual expenses:
| Space used for daycare | 1,800 ÷ 2,000 = 90% |
|---|---|
| × hours fraction | × 31.39% |
| Business use percentage | 28.25% |
| × total home expenses | × $18,000 |
| Deduction | $5,086 |
Ten times over, on the same house, in the same year, from the same records.
The one honest argument for it
There is a real one, and it is not paperwork.
"If you elect to use the simplified method, you cannot deduct any actual expenses... or depreciation... The depreciation deduction allowable for that portion of the home is deemed to be zero for a year you use the simplified method."
Deemed to be zero is the phrase that matters, and it matters years later. When you sell the house, gain attributable to depreciation deducted after 6 May 1997 is not covered by the exclusion on the sale of a main home. A simplified year contributes nothing to that reckoning, because there was no depreciation allowable to deem.
That is genuinely a benefit. Weigh it honestly: you are trading roughly $4,600 of current deduction, in the example above, for removing one year's share of depreciation from a future calculation. For almost every provider that is a bad trade — the deduction is certain and now, the recapture is contingent and later, and the amounts are not comparable. But it is the argument, and it is worth knowing it exists rather than being told the simplified option is simply worse.
If you have not met the recapture rule yet, it is the last section of the time-space article, including the part about allowed or allowable — which is why skipping depreciation under the full method does not achieve the same thing.
You are not locked in
This is the part providers get wrong in the cautious direction, and it costs them a year:
"You choose whether or not to figure your deduction using the simplified method each tax year."
"A change from using the simplified method in one year to actual expenses in a succeeding tax year, or vice versa, is not a change in method of accounting."
No election form. No permission. No consistency requirement across years. Which means the right way to decide is to compute both for one year and take the larger — and the numbers you need for the comparison are already in front of you, because the hours fraction is shared.
One asymmetry to know before you switch into a simplified year:
"If you used actual expenses to figure your deduction for business use of the home in a prior year and your deduction was limited, you cannot deduct the disallowed amount carried over from the prior year during a year you figure your deduction using the simplified method."
A carryover from a limited year sits still through a simplified year. If you are carrying one, that is a reason to stay on actual expenses until it clears.
What the simplified option does not save you
The attendance log. The rate reduction is computed from the same hours fraction the full method uses, so the records that support one support the other — the name of each child, the dates and hours of attendance.
What it saves is the expense side: totalling the utilities, the repairs and the depreciation schedule for the house. That is an afternoon.
In the example above, that afternoon cost $4,615.
Before you choose
- Work out the hours fraction. You need it either way.
- Multiply your actual daycare square footage by it, and compare against 300. If your daycare space is over 300 square feet, the simplified option is already discarding the difference.
- Total the home expenses once. One afternoon decides the year.
- Then choose — and choose again next year.
A last word on the source. Publication 587 as published is the edition prepared for 2025 returns; a 2026 edition is not out yet. The $5 rate, the 300 square foot cap and the daycare rate reduction are long-standing rules rather than annual figures, but if you are reading the publication for a number that changes yearly, check which edition you have open before you rely on it.
