Home office deductions split by worker type: 1099 contractors deduct square footage on Schedule C; employees lost the deduction in 2018, and employer reimbursement adds taxable income in some plans.
The Lines
- Contractors: regular, exclusive use of a workspace for business; square footage × home costs (utilities, insurance, rent share) follow the records trail. The 1099 stack is in the 1099 guide, and the contract terms in the contract guide.
- Employees: employer reimbursement for equipment/internet can read as wages; the receipts trail is in the reimbursement guide (same audit logic).
- Remote policy: written charter, work hours, and core hours prove business use; the policy anatomy is in the policy guide and the remote records in the remote records guide.
State tax lines follow the work location in the remote termination guide, and the W-4 dial in the W-4 guide. The comp archive is in the records guide.

Contractors: the exclusive-use test comes first
A home office deduction requires a space used regularly and exclusively for business. That is the gate; the math comes after. Mixed-use rooms, a desk in the bedroom used for personal browsing, and a “home office” claimed only in photos all fail the test.
- Measure honestly. Record the room dimensions and the total heated area of the home, and keep a floor-plan note with the date.
- Choose the method with your CPA: actual costs allocate utilities, insurance, rent or mortgage interest, and depreciation by business-use percentage; a simplified method exists with a per-square-foot rate and a capped area, and the current figures should be confirmed with IRS guidance rather than remembered.
- Keep the supporting bills: utilities, rent, insurance, and any improvements made to the space.
- Separate mileage: client travel and supply runs are a different deduction with a log, not part of the office line.
- Watch the recapture rules: depreciation claimed on a converted space can affect the gain when you sell. Ask your CPA before claiming it.
Contractors also carry the self-employment tax and the estimate calendar, so the office line is only one part of the year. Keep the records the same way you keep invoices, because an audit asks for dates and areas, not adjectives.
Employees: reimbursement is the only clean route
For most employees, home-office costs are not deductible on a personal return under current federal law; that changed for tax years starting in 2018, and the suspension has been extended by later legislation. Confirm the current treatment with IRS guidance before you plan a deduction.
- Ask for an accountable reimbursement plan: requirements, receipts, deadlines, and the payment method. Payments under a proper plan are not income.
- Watch stipends. A flat monthly stipend without receipts is often treated as wages and shows up on the W-2. See the W-2 entry for how that changes withholding.
- Ask about equipment. Company-provided hardware is not your deduction; a buy-your-own setup with a stipend is a reimbursement question.
- State expense rules differ. Some states require employers to reimburse necessary business expenses incurred as an employee. Check the wage claim entry and your state on the state map.
Send one written ask to HR and payroll: “Please confirm in writing the remote stipend amount, whether receipts are required, whether the payment is reported as wages, and the reimbursement process for required equipment and internet.” Keep the reply; it is the document that answers an examiner or a wage dispute later.
The records that survive a question
Whether you are a contractor or an employee, the same five records answer most challenges:
- A dated measurement of the workspace and the home’s total area, with the business-use percentage.
- A photo or floor-plan note showing the space is used for work.
- Bills and receipts: utilities, internet, insurance, rent, and any room-specific improvement.
- A reimbursement file: the plan document, the requests you sent, the payments received, and how each was reported.
- An equipment inventory: what you own, what the employer owns, and who paid.
Log the review dates in the application tracker alongside quarterly estimate dates, because a mid-year switch from contract to employment changes both the deduction picture and the withholding. If you are negotiating the conversion, put the stipend and equipment terms in the acceptance letter with the offer acceptance email, so the reimbursement plan is written before you start.
| Worker type | What you can claim | Proof required |
|---|
| 1099 contractor | Home office allocated by business use, plus mileage | Measurements, bills, logs, exclusive-use evidence |
|---|
| W-2 employee | Employer reimbursement under an accountable plan | Plan document, receipts, deadlines, payment records |
|---|
| Both, mid-year switch | Only the lines that match the status on each date | Payroll records and the effective date of the change |

Frequently Asked Questions
- Can a W-2 employee deduct a home office?
- For most employees, no: unreimbursed employee deductions are suspended for federal purposes under current law, and the treatment has been extended by later legislation. Confirm the current rule with IRS guidance and pursue reimbursement instead.
- What does an accountable reimbursement plan require?
- A business connection, substantiation with receipts and dates, and a deadline to return excess amounts. Payments under a proper plan are not wages; a flat stipend without substantiation usually is, and it shows up on your W-2.
- How do I prove exclusive business use?
- A dated measurement of the room and the home, a floor-plan note or photo, bills allocated by percentage, and a record showing the space is used only for work. Mixed-use rooms fail the test, so measure before you claim.
- Is internet deductible when I work remotely?
- For a contractor, the business-use portion can be deductible with records. For an employee, it is normally a reimbursement question. Ask for the plan type in writing and keep the bill with the percentage you used.
Business-use percentages, deduction paths, and reimbursement mandates are federal tax rules and state mandates, with the state side graded in this build from reported sources. Confirm the reimbursement mandate and the claim deadline with the state agency named on the state rule pages, keep the ISP bill, the remote approval email, and the log in one dated file, and ask for the accountable structure in writing with the remote work request generator.
