Home Office Deduction: Simplified vs. Regular Method (2026)

Home office deduction simplified vs regular method explained by Robert Allen Bautista, Kansas City tax preparer

If you run a business from home, the home office deduction can be worth hundreds or a few thousand dollars a year. It is also one of the most misunderstood deductions. Here is who qualifies, how the two calculation methods compare, and how to choose.

Who qualifies

  • You must be self-employed (or a business owner). W-2 employees who work from home cannot claim it on their federal return under current law, even if the employer requires remote work.
  • Regular and exclusive use. The space must be used only for business, on a regular basis. A desk in the corner of the guest room can qualify if that corner is used only for work; the kitchen table usually does not.
  • Principal place of business, or a place where you regularly meet clients. If you do your administrative and management work there and have no other fixed location for it, that generally counts.

Two exceptions to the exclusive-use rule: space used regularly to store inventory or product samples, and qualifying home day care.

Method 1: Simplified

Multiply the square footage of your office by $5, up to 300 square feet, for a maximum deduction of $1,500.

  • No Form 8829 and no tracking of utilities or repairs
  • No depreciation, so nothing to recapture when you sell the home
  • Your full mortgage interest and property taxes stay on Schedule A if you itemize

Method 2: Regular (actual expenses)

Figure the business percentage of your home (office square feet divided by total square feet) and apply it to actual expenses on Form 8829:

  • Rent, or mortgage interest and property taxes
  • Utilities, homeowners or renters insurance, HOA dues
  • Repairs and maintenance (direct office repairs at 100%)
  • Depreciation on the business portion of a home you own

Example

A consultant rents a 1,000-square-foot apartment for $1,400 a month and uses a 150-square-foot room as a dedicated office (15%). Annual rent, utilities and renters insurance total about $19,500. Regular method: 15% × $19,500 = $2,925. Simplified method: 150 × $5 = $750. For renters with a real dedicated room, the regular method often wins by a lot.

How to choose

  • Renters with a dedicated room: run the regular method; it is often much larger.
  • Homeowners: the regular method may be larger, but depreciation is recaptured and taxed when you sell. Many owners with small offices prefer simplified.
  • You can generally switch methods from year to year.
  • The deduction cannot create a business loss; excess regular-method expenses carry forward.

Records to keep

A floor plan or measurements, photos of the space, rent or mortgage statements, utility bills, and notes showing how the space is used. If you are ever asked, documentation is what makes the deduction stick.

How Self-Employment Tax Works, Step by Step (2026)

Image
If you freelance, drive for an app, or run a one-person business, the tax that surprises people most is not income tax. It is self-employment tax , the Social Security and Medicare tax that an employer would normally split with you. When you work for yourself, you pay both halves. Here is exactly how it is calculated, step by step. Step 1: Figure your net profit Self-employment tax is based on net earnings, not gross revenue. Start with what you were paid, then subtract ordinary and necessary business expenses on Schedule C (or your share of partnership income on Schedule K-1). Every legitimate expense you record lowers both income tax and self-employment tax. Step 2: Multiply by 92.35% You do not pay the tax on 100% of profit. The IRS lets you multiply net profit by 92.35% first. This mirrors the fact that employees do not pay Social Security and Medicare on the employer's share. If net earnings after this step are under $400, you generally owe no self-employment tax. Step ...

How Long to Keep Tax Records (and Exactly What to Keep)

Image
"How long do I have to keep this?" is one of the most common questions I get, usually from someone holding a shoebox of receipts. The answer depends on how long the IRS has to question a return. Here is the practical version. The time limits 3 years from the date you filed (or the due date, if later): the general rule for most returns. 6 years if you left out more than 25% of the gross income you should have reported. 7 years if you claim a loss from worthless securities or a bad debt deduction. Indefinitely if you never filed a return or filed a fraudulent one. 4 years for employment tax records if you have employees, from the date the tax was due or paid, whichever is later. Records that follow the asset, not the year Keep records for property (your home, rental property, equipment, investments) until the time limit expires for the year you sell or dispose of it. That means purchase documents, improvements and depreciation records can need to be kept for many years. H...

Living in Kansas, Working in Missouri (or the Reverse): State Tax Basics

Image
In the Kansas City metro, thousands of people sleep in one state and work in the other. That usually means filing two state returns. The good news: the system is designed so you are not taxed twice on the same income. Here is how it works. The core rule Your home state taxes all of your income , wherever you earn it. The state where you work taxes the income earned there , as a nonresident. Your home state gives you a credit for the tax you paid to the work state, so the same dollars are not fully taxed twice. Kansas and Missouri do not have a reciprocity agreement, so you generally cannot just file in your home state and skip the other one. Live in Kansas, work in Missouri Missouri nonresident return (Form MO-1040 with the nonresident section) reporting the wages earned in Missouri. Your employer will usually withhold Missouri tax. Kansas resident return (Form K-40) reporting all of your income, then claiming the credit for taxes paid to other states for the Missouri tax. Kansas C...
