The Home Office Deduction: Simplified vs. Regular Method

Last reviewed October 2026 by the 1099tax.app team. These tools give estimates, not tax or legal advice.

If you run a business from home, part of what you spend on your house or apartment may be deductible. It's one of the most useful breaks for freelancers and small business owners, and one of the most misunderstood. The IRS offers two ways to figure it: a simplified method that takes a minute, and a regular method that takes more records and is often worth more. This guide explains who qualifies, how each method works, and how to choose.

Who can claim it

Under IRS rules (Publication 587), a part of your home qualifies if you use it:

  1. Exclusively and regularly for your business. A desk in the corner of the guest room you also use for guests doesn't qualify. A spare room used only for work does.
  2. As your principal place of business, or as a place where you regularly meet clients, or as a separate structure (such as a detached studio) used for the business.

Your home office can count as your principal place of business even if you do some work elsewhere, as long as you use it for administrative or management work and have no other fixed location where you do that work.

There are limited exceptions to the "exclusive use" rule for storing inventory or product samples, and for licensed daycare providers.

Employees can't claim it. Since 2018, people who work from home as W-2 employees can't deduct a home office on their federal return, even under the simplified method. The deduction is for the self-employed: Schedule C filers and farmers on Schedule F. Partners may have separate rules.

The simplified method

According to the IRS, the simplified option works like this:

  • $5 per square foot of the space used for business, up to 300 square feet, for a maximum of $1,500 a year.
  • Mortgage interest and property taxes stay fully on Schedule A if you itemize. You don't split them.
  • No depreciation is claimed, so there's no depreciation to recapture when you sell your home.
  • The deduction can't be more than your business's gross income minus its other expenses, and any unused amount can't be carried forward.

The regular (actual expense) method

With the regular method, you figure your business-use percentage, usually the office's square footage divided by your home's total square footage, and apply it to your actual home costs. You report it on Form 8829. Costs can include:

  • Indirect expenses (the whole home): rent, mortgage interest, property taxes, homeowners insurance, utilities, general repairs, HOA fees
  • Direct expenses (the office only): painting or repairs to that room, 100% deductible
  • Depreciation on the business part of the home, if you own it

The deduction is limited to the income from the business, but any unused amount can be carried forward to future years. The trade-off: depreciation you claim (or could have claimed) is taxed when you sell the home, as unrecaptured Section 1250 gain at up to 25%.

A worked example

A self-employed bookkeeper owns a 2,000 sq ft home and uses a 200 sq ft room only for work, which is 10% of the home. 2026 home costs:

ExpenseAnnual
Mortgage interest$12,000
Property taxes$4,000
Utilities$3,600
Homeowners insurance$1,400
General repairs$1,000
Total$22,000

Simplified method: 200 sq ft × $5 = $1,000. All $16,000 of mortgage interest and property taxes stay on Schedule A if they itemize.

Regular method:

  • 10% × $22,000 = $2,200
  • Depreciation: suppose the house's basis (excluding land) is $300,000. The business part is $30,000, depreciated over 39 years, which is about $769 a year once fully in service.
  • Total: about $2,969

The regular method is worth roughly $1,969 more here. Two things narrow the gap. First, $1,600 of it (10% of the mortgage interest and property taxes) would otherwise have been an itemized deduction. Since most people now take the standard deduction ($16,100 single in 2026), it's often lost unless moved to Schedule C. Second, the $769 of depreciation each year will be taxed at up to 25% when the home is sold. For a renter, the regular method usually wins by more, because rent is fully deductible in proportion and there's no depreciation.

How to choose

Consider the simplified method if:

  • Your office is small, or your home costs are low
  • You rent and keep few records, or you want the least paperwork
  • You may sell your home soon and want to avoid depreciation recapture

Consider the regular method if:

  • Your home costs are high, or your office is a large share of the home
  • You rent, since rent can be a big deductible expense
  • You have business losses you'd like to carry forward

You can switch methods from year to year. You pick by using the method on a timely filed original return, and you can't change it later for that same year. If you move from simplified back to regular, the IRS requires you to use the optional depreciation tables for the later year.

Common mistakes

  1. Claiming a room that isn't used only for business. A family computer or a guest bed can disqualify it.
  2. Claiming it as a W-2 employee. The deduction isn't available for employees in 2026.
  3. Exceeding the income limit. The deduction can't create a loss from the home office.
  4. Forgetting depreciation recapture under the regular method when you sell.
  5. Counting the whole internet or phone bill. Only the business-use share is deductible.
  6. Keeping no measurements or photos. Records help if the IRS asks.

Frequently asked questions

Possibly, if the home office is your principal place of business for administrative work and you don't do that work elsewhere. The facts matter.
