Quick Answer
You can deduct rental expenses proportional to the space you rent out, typically 20-40% of home expenses for house hackers. If you rent out 2 of 5 rooms, you can deduct 40% of mortgage interest, utilities, and maintenance costs, potentially saving $2,000-5,000 annually in taxes.

Best for house hackers who typically take the standard deduction but rent out rooms for income
House hacking creates rental deductions even if you don't itemize
When you rent out part of your primary residence (house hacking), those rental expenses go on Schedule E — completely separate from your personal itemized deductions. This means you can take the standard deduction for your personal taxes AND deduct rental expenses for the business portion of your home.
The key is the business use percentage. If you rent out 2 bedrooms in a 5-bedroom house, 40% of your home expenses become deductible rental expenses, even if you never itemize personal deductions.
How to calculate your business use percentage
The IRS allows two methods for calculating business use:
Method 1: Room count (simpler)
Method 2: Square footage (more accurate)
Choose the method that gives you the higher legitimate percentage, but be consistent year to year.
Example: $75,000 house with 40% rental use
Mike owns a $300,000 house and rents out 2 of 5 bedrooms for $800 each ($1,600/month total rental income). His annual expenses and deductions:
Tax impact: At a 22% tax bracket, Mike saves $2,015 in federal taxes (22% × $9,160), plus state tax savings.
What expenses you can deduct
Direct rental expenses (100% deductible):
Shared home expenses (business percentage deductible):
Depreciation: You can depreciate the business portion of your home's value over 27.5 years. For a $300,000 home with 40% business use, that's $120,000 ÷ 27.5 = $4,364 in annual depreciation deduction.
Co-living as a subletter: Limited but real deductions
If you rent an apartment and sublease rooms to others, you're running a rental business with your landlord's permission. You can deduct:
Example: You pay $2,000/month rent and sublease 1 of 3 bedrooms for $800. You can deduct $667/month ($8,000/year) as a rental expense — the proportional rent cost for the room you're subletting.
Important limitations and requirements
14-day rule doesn't apply: Unlike vacation rentals, there's no minimum rental period requirement for house hacking. Even occasional Airbnb guests create deductible expenses.
Depreciation recapture: When you sell your home, you'll owe taxes on depreciation deductions you claimed. Plan for this by setting aside money or consider a 1031 exchange to a full rental property.
Record keeping requirements:
What you should do
Start by calculating your business use percentage using both methods and choose the higher legitimate result. Then gather all your home expense receipts from this year — mortgage statements, utility bills, insurance policies, and maintenance receipts. Use our return scanner to check if you missed claiming rental deductions from previous house hacking years.
Key takeaway: House hackers can deduct 20-40% of home expenses as rental deductions on Schedule E, separate from personal itemized deductions. A typical $300,000 home with 40% business use generates $9,000+ in annual deductions, saving $2,000-3,000 in taxes.
Key Takeaway: House hackers deduct their business use percentage (typically 20-40%) of all home expenses on Schedule E, generating $9,000+ in annual deductions that save $2,000-3,000 in taxes, even while taking the standard deduction personally.
Tax treatment comparison for different co-living and house hacking arrangements
| Arrangement Type | Deductible Expenses | Tax Form | Typical Annual Deductions | Complexity Level |
|---|---|---|---|---|
| Own home, rent rooms | 40% of all home expenses | Schedule E | $5,000-15,000 | Medium |
| Rent apartment, sublease rooms | Proportional rent + utilities | Schedule E | $20,000-40,000 | Medium |
| Co-living membership | Limited to personal items | None typically | $0-500 | Low |
| Duplex house hack | 50% of all property expenses | Schedule E | $8,000-20,000 | High |

Best for young adults new to house hacking or co-living who want to understand the basics
House hacking 101: Turning roommates into tax deductions
If you're renting out rooms in a house or apartment you live in, congratulations — you're running a rental business! This means legitimate business expenses that reduce your tax bill.
The basic rule: any expense that benefits your rental tenants becomes partially deductible. If you rent out 1 of 3 bedrooms, roughly 33% of your shared home expenses become tax deductions.
Simple example for a young house hacker
Alex buys a $250,000 duplex, lives in one unit, and rents out the other for $1,200/month. Since 50% of the property generates rental income, Alex can deduct 50% of:
Total deductions: $8,100, saving roughly $1,782 in taxes (22% bracket)
Co-living arrangements: What counts as deductible
If you're the main tenant subleasing to others:
Getting started: Three key steps
1. Calculate your percentage: Count rooms or measure square footage to determine what portion of your space generates rental income
2. Track everything: Save receipts for all home expenses, even small ones. Property management apps like Stessa or Rentberry can help organize expenses automatically
3. Separate personal vs. business: Keep rental income and expenses in a separate bank account if possible. This makes tax prep much easier
Important for young adults: Even if this is your first year renting out space, you can still claim deductions. The IRS doesn't require you to be profitable immediately — rental businesses often show losses in early years due to depreciation and startup costs.
Key Takeaway: Young house hackers can deduct their rental percentage of home expenses (typically 25-50%), turning ordinary housing costs into tax deductions worth $1,500-3,000 annually in tax savings.

Best for renters who sublease part of their apartment or rent space in co-living arrangements
Subleasing as a renter: Yes, you can deduct expenses
Many renters don't realize that subleasing part of your apartment creates legitimate business deductions. If you're the master tenant subletting to others, you're running a rental business — even in a co-living arrangement.
What you can deduct as a subletting renter:
Realistic example: Subletting in an expensive city
Jenna rents a 3-bedroom apartment in San Francisco for $4,500/month and subleases 2 bedrooms for $1,800 each ($3,600 total income). Her deductible expenses:
Total deductions: $40,500
Rental income: $43,200
Net rental income: $2,700
Jenna pays taxes on only $2,700 instead of the full $43,200 in rental income received.
Co-living memberships vs. traditional subleasing
If you're part of a formal co-living company (like Common, Ollie, or WeLive), your tax situation is different:
Record keeping for renter subletters
Essential documentation:
Pro tip: Use a separate bank account for rental income/expenses. This makes tax preparation much simpler and provides clear business records for the IRS.
Important limitation: You can only deduct expenses that exceed 2% of your adjusted gross income if you itemize personal deductions. But rental business expenses on Schedule E don't have this limitation.
Key Takeaway: Renters who sublease can deduct their proportional rent, utilities, and subletter-related expenses, potentially reducing taxable rental income by $30,000-50,000 annually in high-cost cities.
