Do you pay taxes on house hacking income?

Yes, house hacking income is taxable. The rent you collect counts as income on your tax return, but the rented portion of the property is treated like a business, so you can deduct its share of property tax, insurance, utilities, repairs, mortgage interest and depreciation. When my upstairs tenant pays $1,200/month, that $14,400 a year goes on my return, and the deductions often shrink it a lot.

Yes, but the rented portion comes with deductions that often go unclaimed. Here’s the plain-English version.

This is the question I actually enjoy. The short version: yes, the rent you collect is taxable income. The longer version is more interesting, because house hacking gives you a tax setup that pure homeowners and pure landlords don’t get.

A quick disclaimer before the numbers: this is not tax advice, and I’m not your accountant. This is how the mechanics work in general, run your specific situation past a CPA before you file.

How to report rental income from your tenants

The rent your tenants pay is income. When my upstairs tenant pays about $1,200/month, that is about $14,400 a year, and it goes on my return. Same with the basement short-term rental. There’s no hiding it, and you shouldn’t try.

House hacking tax deductions you can claim

Because you live in part of the building and rent out the rest, you split the property for tax purposes. The rented portion is treated like a business, and a business gets to deduct its expenses.

On the rental percentage of my duplex, I can deduct a share of:

• Property tax and insurance
• Utilities I pay for the building
• Repairs and maintenance, the boiler, the chimney work, ordinary fixes
• Mortgage interest on the rented portion
• Depreciation, a non-cash deduction that often wipes out the rest

That last one does a lot of work. Depreciation lets you deduct a slice of the building’s value every year even though you didn’t spend that cash. It frequently turns “taxable rental profit” into a paper loss. (I wrote a plain-English depreciation explainer here.)

How to split expenses between rental and personal use

You allocate by space, square footage or number of units. If you live in one of two equal units, roughly half the building is “personal” (your home, with its own homeowner perks) and half is “rental” (deductible). The portion you live in doesn’t generate deductible rental expenses, but it also isn’t generating taxable rent. It’s a clean trade.

Taxes after you move out and rent both units

When you move out and rent your old unit, the whole building flips to rental, and your deductions go up accordingly. Two rules from IRS Publication 527 shape that year: the depreciation basis of the unit you just left is the lower of its adjusted basis or its fair market value on the day it becomes a rental (Basis of Property Changed to Rental Use), and the conversion year is split, with that unit’s depreciation starting mid-month and its taxes and insurance allocated to the months it was a rental, not the whole year. The unit that was always rented stays on its existing schedule. That’s part of why house hacking gets better on the tax side over time, not worse.

How much house hacking income you actually pay tax on

You’ll pay tax on house hacking income, but if you’re tracking expenses and claiming depreciation, the taxable number is often far smaller than the cash you collected, and sometimes it’s zero. The mistake isn’t paying the tax. The mistake is collecting the rent and never claiming the deductions you’re owed.

You will pay tax on house hacking income, but with expenses tracked and depreciation claimed, the taxable number is often far smaller than the cash you collected.

Keep clean books from month one. It’s the difference between a deduction you can defend and a guess you can’t.

Frequently asked questions

Do you pay taxes on house hacking income

Yes. Rental income is defined as the rent your tenants pay you, and it goes on your return as income. The rented share of the building is then treated like a business, so its share of the expenses comes off against that income.

What can you deduct when you rent out part of your house

A rental deduction is defined as the share of a building expense that belongs to the rented portion. On that percentage you can deduct property tax, insurance, the utilities you pay for the building, repairs and maintenance, mortgage interest and depreciation.

How do you split expenses between rental and personal use

The split is defined by space, either square footage or the number of units. If you live in one of two equal units, roughly half the building is personal and half is rental, and only the rental half produces deductible expenses.

What is depreciation on a rental property

Depreciation is defined as a deduction for a slice of the building’s value each year even though you did not spend that cash. It frequently turns what looks like a taxable rental profit into a paper loss.
