WFH Tax Deduction Calculator

Estimate your home office tax deduction using simplified or actual expense method — free, instant, no signup

A work-from-home tax deduction lets self-employed individuals and 1099 contractors reduce their taxable income by claiming expenses related to a home office. The IRS offers two methods: the simplified method ($5 per square foot, up to $1,500) and the actual expense method (business-use percentage of real home costs). Since the 2018 TCJA, W-2 employees cannot claim this deduction on federal taxes.

How to Use This WFH Tax Deduction Calculator

If you work from home as a freelancer, independent contractor, or self-employed professional, you may be eligible for a valuable home office deduction that reduces your taxable income. The IRS offers two methods for calculating this deduction, and this calculator lets you compare both side by side to find the one that saves you the most money.

Step 1: Enter Your Office Square Footage

Measure the area of your home that you use regularly and exclusively for business. This must be a dedicated workspace — not a dining table you also use for meals. Enter the square footage of this space in the first field. For the simplified method, only the first 300 square feet count, but entering your actual size helps compare both methods accurately.

Step 2: Enter Your Total Home Square Footage

Enter the total square footage of your entire home. This is used to calculate the business-use percentage for the actual expense method. For example, if your office is 200 square feet and your home is 2,000 square feet, your business-use percentage is 10%. This percentage determines how much of your home expenses you can deduct.

Step 3: Enter Your Annual Home Expenses

Fill in your actual annual home expenses — mortgage interest or rent, utilities (electricity, gas, water), internet service, business phone costs, homeowners insurance, and any repairs or maintenance. These figures are used for the actual expense method calculation. The simplified method ignores these costs entirely and uses a flat $5-per-square-foot rate instead.

Understanding the Two Methods

The simplified method is straightforward: multiply your office square footage (up to 300 sq ft) by $5 for a maximum deduction of $1,500. No expense tracking is needed. The actual expense method calculates your business-use percentage and applies it to your real home expenses, which often results in a larger deduction if you have significant housing costs. You can switch between methods each tax year, but must use the same method for the entire year.

Who Can Claim This Deduction?

Only self-employed individuals, freelancers, and 1099 contractors can claim the work-from-home tax deduction on their federal taxes. The 2018 Tax Cuts and Jobs Act eliminated the home office deduction for W-2 employees through at least 2025. Your home office must pass two IRS tests: it must be used regularly for business and exclusively for business — no personal use of the space is allowed.

Frequently Asked Questions

Is this WFH deduction calculator free to use?

Yes, this work-from-home tax deduction calculator is completely free with no signup, account, or payment required. Use it as many times as you need to compare the simplified and actual expense methods for your home office deduction.

Is my data private when using this tool?

Absolutely. All calculations run entirely in your browser using JavaScript. No financial data, expense figures, or personal information is ever sent to any server or stored anywhere. You can even disconnect from the internet and the calculator will still work. Your information stays completely private on your device.

Who qualifies for the home office deduction?

The home office deduction is available to self-employed individuals, freelancers, and independent contractors who use part of their home regularly and exclusively for business. Since the 2018 Tax Cuts and Jobs Act (TCJA), W-2 employees can no longer claim the home office deduction on their federal taxes, even if they work from home full-time.

What is the simplified home office deduction method?

The simplified method lets you deduct $5 per square foot of your home office, up to a maximum of 300 square feet ($1,500 maximum deduction). You do not need to track actual expenses or calculate the business-use percentage of your home. This method is easier but may result in a smaller deduction than the actual expense method.

How does the actual expense method work?

The actual expense method calculates your deduction by dividing your office square footage by your total home square footage to get a business-use percentage. You then apply that percentage to eligible home expenses like mortgage interest or rent, utilities, insurance, internet, phone, and repairs. This method requires more record-keeping but often yields a larger deduction.

Can I switch between the simplified and actual expense methods?

Yes, you can switch between methods from year to year. However, if you switch from the actual expense method to the simplified method, you cannot claim depreciation for the year you switch. You must also use the same method for the entire tax year — you cannot use simplified for part of the year and actual for the rest.

What expenses count for the actual expense method?

Eligible expenses include mortgage interest (or rent), property taxes, homeowners insurance, utilities (electricity, gas, water), internet service, phone bills used for business, home repairs and maintenance, and depreciation of your home. Only the business-use percentage of each expense is deductible. Expenses that benefit only your office (like painting the office) are 100% deductible.

Does the home office need to be a separate room?

No, your home office does not need to be a separate room, but it must be a clearly defined area used regularly and exclusively for business. A dedicated desk in a corner can qualify if you use that space only for work. However, a kitchen table where you also eat meals would not qualify because it fails the exclusive-use test.
