Plus, taking advantage of all available deductions means more money stays in your pocket. Keyrenter Boise is here to walk through the most important tax tips every landlord should know to make this tax season smooth and save you as much money as possible.
Top Tax Deductions for Landlords
Here are the deductions that can significantly reduce your tax bill. Make sure you’re taking advantage of every single one that applies to you.
Mortgage Interest
If you have a mortgage on your rental property, the interest you pay is probably your biggest deduction. This can save you thousands each year. Your mortgage lender will send you a Form 1098 showing how much interest you paid.
Remember, only the interest portion of your mortgage payment is deductible, not the principal. You can also deduct interest on home equity loans if you used the money for your rental property, credit card interest for rental related purchases, and origination fees and points when you buy or refinance.
Keep clear records separating personal loans from rental property loans. The IRS wants to see that borrowed money went directly to your rental business.

Property Taxes
The property taxes you pay on your rental are fully deductible. Your local government bills you for these, and they can be substantial. Don’t forget to deduct them. This is different from income taxes, which aren’t deductible.
Some areas also charge occupancy taxes or other rental related fees. These are deductible too.
Repairs and Maintenance
This is where many landlords get confused, so pay attention. Repairs and maintenance costs are deductible in the year you pay them, but improvements are treated differently.
Repairs keep your property in good working condition. They fix things that are broken or worn out. Examples include fixing a leaky faucet, patching a hole in the wall, repainting a room, replacing broken windows, or repairing a damaged roof. These costs are fully deductible in the year you pay them.
Maintenance prevents problems and keeps things running smoothly. This includes things like cleaning gutters, servicing the HVAC system, pest control, lawn care, and changing air filters. These are also fully deductible.
The key word is “ordinary and necessary.” If the expense is normal for rental properties and needed to keep yours running, it’s deductible.
Depreciation
Depreciation is a powerful deduction many landlords don’t fully understand. Here’s the simple explanation: rental properties wear out over time. The IRS lets you deduct this wear and tear even though you’re not actually spending money each year.

For residential rental properties, you depreciate the building over 27.5 years. You can’t depreciate land, only the structure and improvements.
Depreciation gets complicated quickly. Work with a tax professional to make sure you’re doing it right. They can also help you with cost segregation, which lets you depreciate certain components faster and save more money sooner.
Home Office Deduction
If you use part of your home exclusively for managing your rental business, you might qualify for a home office deduction. This space must be used regularly and exclusively for business. A corner of your bedroom where you sometimes work doesn’t count. A dedicated office does.
You have two ways to calculate this deduction. The simplified method lets you deduct $5 per square foot of office space, up to 300 square feet. The regular method requires calculating the actual percentage of your home used for business and deducting that percentage of your home expenses like mortgage interest, insurance, utilities, and repairs.
The home office deduction can be valuable but also attracts IRS attention. Make sure you meet all requirements before claiming it.

Common Tax Mistakes Landlords Make
Avoid these errors that cost landlords money every year.
- Don’t forget to report all income. The IRS will notice if you report less rental income than your tenant reports paying.
- Don’t confuse repairs with improvements. Treat them correctly or you’ll either lose deductions or face questions from the IRS.
- Don’t neglect depreciation. Some landlords forget to claim this valuable deduction.
- Don’t use personal funds and rental funds from the same account. Keep separate bank accounts for your rental business to make tracking much easier.
- Don’t wait until tax season to get organized. Do a little work throughout the year and save yourself stress later. And don’t try to deduct personal expenses as business expenses. The IRS catches this and it can get you in serious trouble.
Bottom Line
Tax season doesn’t have to be stressful for landlords. Understanding what you can deduct, keeping excellent records all year, and working with a good tax professional makes the whole process manageable.
Take advantage of every deduction you’re entitled to, stay organized, and plan ahead. Your rental property is an investment, and smart tax management helps you keep more of the income it generates.
