If you use part of your home regularly and exclusively for your freelance business, you can deduct it in one of two ways. The simplified method is $5 per square foot of office, counting no more than 300 square feet, so it tops out at $1,500 a year. The regular method, figured on Form 8829, deducts your business percentage of rent or mortgage interest, utilities, insurance and general repairs, plus costs that apply only to the office and, if you own the home, depreciation. For a 200-square-foot office the simplified method gives $1,000; in the example below the regular method gives $3,000 for a renter and $3,399.96 for an owner.

	Simplified method	Regular method
Formula	Office square feet, up to 300, × $5	Business percentage × indirect expenses + direct expenses + depreciation
Largest possible deduction	$1,500 (300 × $5)	No fixed cap
Where it is figured	Simplified Method Worksheet in the Schedule C instructions	Form 8829
Where it is claimed	Schedule C, line 30	Schedule C, line 30
Proof of home expenses	Not needed to figure the amount	Needed for each expense
Depreciation of the home	None; treated as zero	Business part, straight line over 39 years
Depreciation recapture when you sell at a gain	None for simplified years	Yes
Mortgage interest and real estate taxes	Stay on Schedule A in full if you itemize	Business share moves to Schedule C
Business income limit	Applies	Applies
Amount over the limit	Lost	Carried forward
Choosing the method	Each year, on a timely filed original return	Same

These rules come from IRS Publication 587 for 2025 returns, the 2025 Form 8829 and Schedule C instructions, and the IRS simplified-option pages. The simplified method applies to tax years beginning on or after January 1, 2013, which includes 2026.

The use tests your office has to pass

Both methods share the same qualification rules, and renters and owners can both qualify. The home can be a house, apartment, condominium, mobile home, boat or similar property.

Test	What it requires	How it usually fails
Exclusive use	A specific area used only for the business: a room or a separately identifiable space, with no permanent partition needed	The space doubles as a guest room, den or family computer corner
Regular use	Business use on a regular basis	Use is incidental or occasional
Trade or business	Use in connection with a trade or business	The activity is managing your own investments
Principal place of business	The home is your main business location, judged by the importance of the work and the time spent at each place	You also do substantial administrative work at another fixed location, such as a rented office, and no other route below applies

For freelancers who do the paid work at client sites, the administrative rule usually settles the last test. A home office is your principal place of business if you use it exclusively and regularly for administrative or management tasks, such as billing, bookkeeping, ordering supplies and scheduling, and you have no other fixed location where you do substantial administrative or management work. Doing some of that work in a car or hotel room, having another company do your billing, or choosing home over other available space does not disqualify you.

Two other routes qualify without the principal-place test: a space where you physically meet clients in the normal course of business, when their use of it is substantial and integral to the business (occasional meetings and phone calls are not enough), and a separate free-standing structure, such as a studio or garage, used exclusively and regularly for the business. An office that is merely appropriate and helpful does not qualify. Employees cannot claim the deduction for employee work for tax years beginning after 2017, so a W-2 remote job does not create one.

Storage and daycare exceptions to exclusive use

Space used regularly to store inventory or product samples qualifies without exclusive use if you sell products at wholesale or retail, the home is the only fixed location of that business, and the space is separately identifiable and suitable for storage. So does space used regularly for a daycare business caring for children, people 65 or older, or people who cannot care for themselves, if you have, have applied for or are exempt from the required state license. Daycare space that is also used personally is deducted in proportion to the hours it serves the daycare.

How each method is figured

Simplified method. Multiply the allowable area, which is the smaller of the office’s square footage or 300 square feet, by $5. For part-year use or a change in size, average the monthly area over 12 months, counting only months with at least 15 days of use. Then apply the income limit below. You cannot also deduct actual home expenses or depreciation for that home, but costs unrelated to the home, such as advertising, supplies, and depreciation on furniture and equipment, stay deductible.

Regular method.

Business percentage: office area ÷ total area of the home. If the rooms are about the same size, you can count rooms instead.
Direct expenses, which benefit only the office, such as painting or repairs in that room, are deducted in full.
Indirect expenses for running the whole home, such as rent, mortgage interest, real estate taxes, utilities, insurance and general repairs, are multiplied by the business percentage.
Depreciation, if you own: business percentage × the smaller of the home’s adjusted basis or fair market value when business use began, both excluding land, recovered straight line over 39 years. A full year is 2.564%; the first year is prorated by the starting month (Table 2 in Publication 587).
Apply the income limit, taking depreciation last.

Costs for parts of the home not used for business, such as lawn care or painting another room, are not deductible.

Example: a 200-square-foot office in a 2,000-square-foot home

Assumptions: a full year of qualifying use, an office in use since an earlier year, business profit well above the home office amounts, and the sample annual expenses shown. Business percentage: 200 ÷ 2,000 = 10%.

Sample annual expense	Type	Renter	Owner
Rent	Indirect	$24,000	None
Mortgage interest	Indirect	None	$12,000
Real estate taxes	Indirect	None	$4,000
Utilities	Indirect	$3,600	$3,600
Renters or homeowners insurance	Indirect	$400	$1,500
General repair (furnace)	Indirect	None	$900
Indirect total		$28,000	$22,000
Business share: indirect total × 10%		$2,800	$2,200
Repainting the office	Direct	$200	$200
Depreciation: $390,000 building basis × 10% × 2.564%		None	$999.96
Regular method total		$3,000	$3,399.96
Simplified method: 200 × $5		$1,000	$1,000
Regular method is larger by		$2,000	$2,399.96

For a renter, the two formulas give a quick test: before direct costs, the regular method wins whenever indirect home costs exceed $5 per square foot of the whole home per year, which is $10,000 a year for this home. This renter spends $28,000, or $14 per square foot. Offices over 300 square feet tilt the comparison further, because the simplified method stops counting at 300.

Two adjustments apply to the owner. First, $1,600 of the $2,200 business share is mortgage interest and real estate taxes (10% of $16,000). If you itemize, the simplified method leaves all $16,000 on Schedule A, subject to its usual limits, so the regular method adds only $799.96 to total deductions ($3,399.96 − $1,600 − $1,000). If you take the standard deduction, only the regular method deducts any of that $1,600. Second, depreciation lowers the home’s basis and is recaptured on a gain when you sell, and the basis drops by the depreciation you were entitled to even if you skip claiming it. Simplified-method years count as zero depreciation.

When low business income caps the deduction

Under both methods, the deduction cannot exceed the gross income from the business use of the home minus your other business expenses. If all your business income comes from the home-based business, that is tentative profit on Schedule C, line 29, so the deduction cannot create a loss. Under the regular method, the business share of expenses deductible anyway, such as mortgage interest and real estate taxes if you itemize, comes first, then operating expenses, then depreciation.

Under the regular method, the excess carries forward to the next regular-method year, subject to that year’s limit, even if you have moved. Under the simplified method it is lost, and a regular-method carryover cannot be used in a simplified year; it waits for the next regular-method year.

Example. The renter above, in a slow year with $800 of tentative profit:

	Simplified	Regular
Tentative profit before the home office (Schedule C, line 29)	$800	$800
Home office amount figured	$1,000	$3,000
Allowed this year: the smaller amount	$800	$800
Carried forward	$0	$2,200
Net profit (Schedule C, line 31)	$0	$0

How the deduction lowers self-employment tax

The deduction goes on Schedule C, line 30, which reduces net profit on line 31, and line 31 is the profit carried to Schedule SE, line 2. Self-employment tax is 15.3% (12.4% Social Security plus 2.9% Medicare) of 92.35% of that profit, so below the Social Security wage base each $1,000 of home office deduction cuts it by about $141.30 ($1,000 × 0.9235 × 0.153), before any income tax savings.

In the renter example, the regular method’s $3,000 lowers self-employment tax by $423.89 and the simplified method’s $1,000 by $141.30, a gap of $282.59. For an owner who itemizes, the $1,600 of mortgage interest and real estate taxes lowers only income tax on Schedule A, but on Schedule C it also lowers self-employment tax, by $226.07. The 2026 self-employment tax rates guide covers the wage base, and the self-employment tax calculator shows how a lower profit changes the total.

Choosing a method each year, and switching

You choose a method by using it on a timely filed, original return, and that year’s choice cannot be changed later.
Switching between years needs no IRS consent. Returning to the regular method after a simplified year uses the optional MACRS table; the 2025 Form 8829 instructions give 2.564% for a home first used for business in 2024 under the simplified method.
With two homes in one year, for example after a move, the simplified method can be used for only one of them.

Keep records of the area used, its regular and exclusive use, and, for the regular method, each expense and the home’s basis; a weekly bookkeeping routine covers the receipts. A qualifying principal place of business also makes trips from home to other work locations in the same business deductible, which feeds into standard mileage vs actual car expenses. Whatever the deduction comes to, rent and utilities are overhead to price in with the other hidden costs of freelancing.
