Garage Rental Tax Deductions: What Homeowners Need to Know (2025)

Is Garage Rental Income Taxable?

Yes — garage rental income is taxable under federal law. Whether you earn $100 a month or $600, the IRS considers payments received for renting any portion of your property to be rental income. It must be reported on your federal tax return regardless of whether you receive a 1099 form from your renter.

There is one narrow exception: the 14-day rule. If you rent out your space for fewer than 15 days during the entire tax year, you are not required to report that income and cannot claim deductions against it. Most homeowners renting month-to-month will exceed this threshold by March.

The practical takeaway from renting out garage taxes: report what you earn, but make sure you are also capturing every deductible expense — because the deductions can significantly reduce what you actually owe.

What Expenses Can You Deduct?

The IRS allows you to deduct ordinary and necessary expenses related to your rental activity. For a garage or driveway rental, that covers a meaningful list of costs. You generally deduct a pro-rated share based on the portion of your property dedicated to the rental.

• Depreciation

  If you rent out a garage that is part of your home, you may be able to depreciate the value of that portion of the structure over 27.5 years (residential rental property schedule). Depreciation is often the largest single deduction available and is easy to miss. Keep a record of the original cost and any improvements.

• Maintenance and repairs

  Costs to maintain, clean, or repair the rented space — repainting walls, replacing a garage door spring, fixing a drainage issue — are fully deductible in the year they occur, as long as they are for the rental portion of your property. Capital improvements (adding new features) are depreciated, not expensed immediately.

• Insurance

  If you add a rider to your homeowners insurance policy to cover the rental activity — which you should — the premium for that additional coverage is deductible. If you cannot separate the rental portion from the overall policy, deduct the pro-rated share (square footage of rental space ÷ total home square footage).

• Listing and platform fees

  Any fees you pay to list or manage your rental space are deductible. This includes platform subscription costs like CurbBay's $19/mo plan, which covers listing, tenant screening, payment processing, and lease generation. Keep the receipts or subscription statements.

• Utilities (if included in rent)

  If your renter's rate includes electricity for a shared outlet or lighting, deduct the pro-rated utility cost attributable to the rented space. If utilities are separately metered or not included in rent, this deduction may not apply.

Note: Tax rules change. The above reflects general IRS guidance for 2025. Consult a CPA or tax professional for advice specific to your situation.

How to Report Rental Income on Your Taxes (Schedule E)

Home garage rental income taxes are reported on Schedule E (Supplemental Income and Loss), which flows into your Form 1040. Schedule E is designed for rental property income — it lets you list your gross rental receipts on one line and all your deductible expenses on separate lines below.

The net figure (income minus deductions) is what gets taxed. If your deductible expenses exceed your rental income in a given year — for example, if you had a large repair — you may be able to carry that passive activity loss forward to offset future rental income.

A few things to keep in mind when filing:

• Report income in the year it is received, not the year it was earned (cash-basis accounting)

• Each rental property or space gets its own Part I on Schedule E

• Depreciation requires Form 4562 — most tax software generates this automatically when you enter the asset details

• If your net rental income exceeds $1,000, you may owe quarterly estimated taxes to avoid an underpayment penalty

Why Keeping Records Matters — and How CurbBay Helps

The IRS can audit rental income up to three years after filing (six years if income was significantly understated). That means you need documentation that holds up: signed lease agreements, rent payment records, receipts for repairs, and invoices for any services you deducted.

Without a paper trail, deductions get disallowed. A disallowed depreciation deduction on a two-year garage rental can mean hundreds of dollars in back taxes plus interest. The administrative overhead is not complicated — it is just consistent.

CurbBay builds the paper trail automatically. Every time a renter is approved, the platform generates a signed lease PDF with the rent amount, term dates, and property address — exactly what the IRS expects to see. Payment history is logged in your dashboard, so you can export a full income record at year-end without digging through bank statements. Combined with your receipts for repairs and the $19/mo plan subscription, your deduction documentation is already organized.

If you have not already set up a proper written agreement for your rental, read our guide on how to write a garage rental agreement. A signed lease is not just legal protection — it is also your primary tax record for the income you earned and the terms under which you earned it.

• Signed lease PDF generated automatically for every approved renter

• Monthly payment log exportable from your dashboard — no manual tracking

• Platform subscription is itself a deductible listing fee

• Consistent documentation reduces audit risk and simplifies filing
