Can I deduct My Rent Or Mortage

---

If you work from home and pay rent or a mortgage, you may be able to deduct a portion of these housing costs as a home office expense. The home office deduction allows self-employed individuals and business owners to write off part of their rent or mortgage interest based on the percentage of their home used exclusively for business. Understanding how to calculate this deduction correctly can result in significant tax savings while ensuring you stay compliant with IRS rules.

Who Can Deduct Rent or Mortgage Interest for a Home Office?

Self-employed individuals, freelancers, independent contractors, and small business owners who maintain a dedicated home office space can deduct a portion of their rent or mortgage interest. The key requirement is that you must use a specific area of your home regularly and exclusively for business purposes.

W-2 employees working remotely cannot deduct home office expenses, including rent or mortgage interest, on their federal tax returns. This deduction was eliminated for employees under the Tax Cuts and Jobs Act for tax years 2018 through 2025.

To claim any rent or mortgage deduction, you must first qualify for the home office deduction by meeting the IRS’s “exclusive and regular use” test. Your home office space cannot be used for personal activities—it must be dedicated solely to your business.

How Much Can You Deduct?

The amount you can deduct depends on what percentage of your home is used for business. There are two methods for calculating your home office deduction: the simplified method and the regular method.

The Simplified Method allows you to deduct $5 per square foot of home office space, up to a maximum of 300 square feet. This means the maximum deduction using the simplified method is $1,500 per year. This method is easier because you don’t need to track actual expenses or calculate percentages, but it may provide a smaller deduction than the regular method.

The Regular Method requires you to calculate the percentage of your home used for business and apply that percentage to your actual housing costs. If your home office is 200 square feet and your entire home is 2,000 square feet, your business use percentage is 10%. You would then deduct 10% of your eligible housing expenses, including rent or mortgage interest.

Deducting Rent Payments

If you rent your home or apartment, you can deduct the business-use percentage of your total annual rent. For example, if you pay $2,000 per month in rent ($24,000 per year) and your home office represents 15% of your living space, you can deduct $3,600 per year in rent expenses.

Rent deductions are straightforward because the entire rent payment is potentially deductible based on your business-use percentage. Keep copies of your lease agreement and rent payment records as documentation.

Deducting Mortgage Interest

Homeowners cannot deduct their entire mortgage payment—only the mortgage interest portion is deductible as a home office expense. Your monthly mortgage payment typically includes principal, interest, property taxes, and possibly insurance (PMIP). Only the interest portion qualifies for the home office deduction.

For example, if you pay $2,000 per month on your mortgage and $1,200 of that is interest, and your home office is 10% of your home, you can deduct $120 per month ($1,440 per year) in mortgage interest for your home office.

You’ll find your annual mortgage interest amount on Form 1098, which your lender sends you each year. Apply your business-use percentage to this amount to determine your deductible mortgage interest.

Other Housing Costs You Can Deduct

Beyond rent or mortgage interest, the regular method allows you to deduct your business-use percentage of:

∙ Property taxes (homeowners only)

∙ Homeowners or renters insurance

∙ HOA fees

∙ Security system costs related to your home

These additional deductions can add up, making the regular method more beneficial than the simplified method for many taxpayers, especially those with larger home offices or higher housing costs.

Calculating Your Business-Use Percentage

To use the regular method, you need to accurately calculate what percentage of your home is used for business. There are two acceptable methods:

Square footage method: Divide your home office square footage by your home’s total square footage. A 150-square-foot office in a 1,500-square-foot home equals 10% business use.

Rooms method: If all rooms in your home are roughly the same size, you can divide the number of business rooms by total rooms. One dedicated office room in a 10-room house equals 10% business use.

The square footage method is more precise and generally preferred, especially if room sizes vary significantly. Measure your office space carefully and document your calculations in case of an audit.

Documentation Requirements

The IRS may scrutinize home office deductions, so proper documentation is essential. Keep records of:

∙ Lease agreements or mortgage statements

∙ Form 1098 (Mortgage Interest Statement) for homeowners

∙ Rent payment receipts or bank statements

∙ Floor plan or diagram showing your home office location and measurements

∙ Photos of your dedicated home office space

∙ Records of all housing expense payments

Strong documentation proves your home office meets IRS requirements and supports your deduction calculations.

Depreciation Considerations for Homeowners

When you claim a home office deduction using the regular method, you must also depreciate the business portion of your home. This creates a future tax consequence: when you sell your home, you may owe depreciation recapture taxes on the portion you’ve been depreciating.

The simplified method avoids depreciation entirely, which is one reason some homeowners prefer it despite the potentially smaller deduction. Consider consulting a tax professional to understand the long-term implications of home depreciation.

What If You Have Multiple Work Locations?

If your business requires you to meet clients at another location or if you maintain an office elsewhere, you can still claim a home office deduction if your home office is used for substantial administrative or management activities. For example, a contractor who works at job sites but does all billing, scheduling, and paperwork from a home office can still claim the deduction.

However, if you maintain another primary place of business and your home office is merely a convenience, you may not qualify for the deduction.

Common Mistakes to Avoid

Don’t claim a deduction for a space that’s used for both business and personal purposes. If you work at a desk in your bedroom that you also use for personal activities, it doesn’t qualify. The exclusive use requirement is strict.

Don’t forget that if you’re using the regular method, you can only deduct mortgage interest, not your principal payments. Many taxpayers mistakenly try to deduct their entire mortgage payment.

Make sure you qualify for the home office deduction before claiming rent or mortgage interest. If your home office doesn’t meet the regular and exclusive use test, none of your housing costs are deductible.

Bottom Line

Self-employed individuals who maintain a qualifying home office can deduct a portion of their rent or mortgage interest based on their business-use percentage. The simplified method offers ease of calculation with a maximum $1,500 deduction, while the regular method requires more record-keeping but often provides larger deductions. Calculate both methods to determine which benefits you most, maintain thorough documentation, and ensure your home office space meets IRS requirements for exclusive business use.
