Home Office Tax Deductions for New Hampshire Freelancers in 2026
New Hampshire freelancers can deduct home office expenses on federal taxes via the simplified method ($5/sq ft, capped at 300 sq ft) or actual-expense method (Form 8829). New Hampshire has no state personal income tax, so home office deductions reduce only your federal AGI; no state benefit applies.
Do you qualify for the home office deduction in New Hampshire?
The IRS requires the home office be used regularly and exclusively for your business per IRS Publication 587. New Hampshire largely follows federal rules, with one notable variation:
New Hampshire has no state personal income tax on wages or freelance income. The Interest and Dividends tax is being phased out by 2027. No state benefit from home office deduction beyond federal.
- Regular use: the space must be used on a continuing basis (monthly or weekly), not occasional.
- Exclusive use: the space must not be used for personal purposes (no kid's homework area on the same desk).
- Principal place of business: the home office must be your principal place of business OR a place where you meet clients.
Federal home office deduction: simplified vs actual
Two methods to calculate; you pick whichever produces the larger deduction:
| Method | How it works | Maximum | Best for |
|---|---|---|---|
| Simplified | $5 per sq ft of dedicated office space | $1,500 (300 sq ft cap) | Small home offices; minimal recordkeeping |
| Actual expenses | Pro-rata share of mortgage interest, property tax, utilities, repairs, depreciation, etc. | No cap (limited by business income) | Large home offices, high mortgage/utility costs, depreciation worth claiming |
Per the IRS, taxpayers using the actual-expense method file Form 8829 (Expenses for Business Use of Your Home) alongside Schedule C.

Frequently asked questions about New Hampshire home office deductions
Can I deduct my entire mortgage payment if I have a home office?
No. Only the business-use percentage of mortgage interest (not principal) is deductible via Form 8829. If your home office is 10% of your home's square footage, you can deduct 10% of the mortgage interest on your Schedule C.
Does New Hampshire require a separate home office form?
New Hampshire has no state income tax form for wages or freelance income, so no separate state form is needed. Use federal Form 8829 for your home office deduction.
Can W-2 employees in New Hampshire deduct home office expenses?
For tax year 2026, W-2 employees cannot deduct unreimbursed home office expenses on federal returns under the Tax Cuts and Jobs Act (in effect through 2025; pending reauthorization in 2026). Some states allow miscellaneous itemized deductions even when federal does not; New Hampshire has no state income tax on wages; only federal TCJA limitation applies..
What's the difference between depreciating my home and the simplified method?
The actual-expense method (Form 8829) lets you depreciate your home over 39 years for the business-use portion. The simplified method does NOT include depreciation. If you sell your home later, depreciation claimed under Form 8829 must be recaptured at sale; the simplified method has no recapture obligation. For most freelancers staying under the $1,500 simplified cap, the simplified method is the right choice.
Can I claim home office deductions if I rent in New Hampshire?
Yes. Renters can deduct the business-use percentage of rent + utilities + renter's insurance via Form 8829, the same as homeowners can deduct mortgage interest + property taxes. New Hampshire renters use the same federal calculation; state treatment follows the federal AGI deduction.
