Business and Rental Tax Deductions You Might Be Missing

Tax deductions are one of the most important tools you have to reduce how much you owe in taxes as a business owner or landlord. In simple terms, a tax deduction is a cost you can subtract from your income before the government calculates your tax bill. According to the Internal Revenue Service (IRS), businesses can generally deduct expenses that are both ordinary and necessary in carrying on their trade or business.

This guide explains common deductions for small businesses and rental property owners, how these write-offs work in practice, and what you should document to support your claims. It is designed for general information only and is not a substitute for personalized legal or tax advice.

Understanding What Counts as a Deductible Expense

The IRS uses two key terms to decide whether an expense is deductible for a business:

• Ordinary – a cost that is common and accepted in your industry.
• Necessary – a cost that is helpful and appropriate for your business, even if it is not absolutely essential.

For landlords, the same basic idea applies. Expenses that are directly related to owning, operating, and maintaining rental property are typically deductible if they are reasonable and properly documented.

Not every payment you make is deductible. For example, you generally cannot deduct personal living expenses, fines or penalties, or the value of your own unpaid time. You also must distinguish between current expenses (like utilities and minor repairs) and capital expenses (such as buying a building or doing a major renovation), which are often recovered through depreciation rather than an immediate deduction.

Key Tax Deductions for Small Businesses

Most small business owners, including freelancers and independent contractors, have access to a core group of common deductions. These write-offs help reduce taxable income and can significantly impact your bottom line.

1. Home Office and Workspace Costs

If you use part of your home regularly and exclusively as your principal place of business or to meet clients, you may qualify for the home office deduction. Expenses associated with that space can be deducted using either the simplified or the regular method.

• Simplified method: multiply up to 300 square feet of qualified home office space by a set rate per square foot (currently $5), which yields a maximum deduction of $1,500 for the home office portion.
• Regular method: calculate the percentage of your home used for business and apply that percentage to eligible costs, such as rent or mortgage interest, utilities, and homeowners insurance.

Separate business premises, such as rented office space, retail stores, or studios, are usually fully deductible as business rent, provided you do not receive equity or title in the property.

2. Vehicle and Travel Deductions

Using your car or truck for business may allow you to deduct a portion of the costs associated with operating it. The IRS provides a standard mileage rate that businesses can use instead of tracking actual costs. If a vehicle is used for both business and personal reasons, only the business portion is deductible, based on miles or another reasonable method.

• Standard mileage method: multiply business miles driven by the applicable IRS rate per mile (for 2026, the IRS publishes this annually).
• Actual expense method: track fuel, repairs, insurance, registration fees, depreciation, and allocate the business percentage of those costs.

Work-related travel away from your tax home that requires you to sleep or rest can also be deductible. This may include airfare, lodging, taxis or rideshares, and a portion of meals, provided the trip is primarily for business and properly documented.

3. Payroll, Benefits, and Contractor Costs

Compensation paid to employees and certain benefits you provide are generally deductible as business expenses. These can include:

• Wages and salaries.
• Commissions and bonuses.
• Employer-paid payroll taxes (such as the employer share of Social Security and Medicare).
• State unemployment insurance and similar payroll-related taxes.
• Employer contributions for employee health insurance and retirement plans.

Payments to independent contractors are also typically deductible, but you may have separate reporting obligations (such as issuing Form 1099). Keep written contracts and accurate records to show that the work performed was business-related.

4. Supplies, Equipment, and Technology

Most businesses spend money on tools and supplies needed for day-to-day operations. Many of these costs can be deducted in the year they are incurred, such as:

• Office supplies like paper, pens, and printer ink.
• Computers, printers, and peripherals used for business.
• Business software, cloud subscriptions, and website hosting services.
• Specialized equipment or machinery used in your trade.

For larger purchases of qualifying equipment and software, businesses may use provisions such as Section 179 expensing, which allows the cost of certain assets to be deducted in the year they are placed in service, subject to annual limits and income restrictions. This can accelerate deductions compared to traditional depreciation.

5. Professional Services, Insurance, and Other Overheads

Many recurring costs that support your business infrastructure are also deductible, including:

• Fees paid to accountants, lawyers, consultants, and other professionals for business-related work.
• Business insurance premiums, such as general liability, commercial property, cyber liability, and commercial auto coverage.
• Utilities, internet service, and business phone lines used in your workspace or office.
• Bank fees and merchant processing charges connected to business accounts.
• Advertising and marketing expenses, including online ads, printed materials, and trade show costs.

These expenses often add up over the year, so tracking them consistently makes it easier to claim all available deductions when filing your tax return.

6. Startup Costs and Organizational Expenses

If you are launching a new business, certain startup expenses may be deductible even before you officially open your doors. These can include market research, training costs, fees for setting up your legal entity, and advertising for the grand opening.

Current IRS rules allow businesses to deduct up to a specified amount of startup and organizational costs in their first year, with any remaining amounts amortized over a number of years. While the exact dollar limits can change over time, the general structure of deducting a portion upfront and spreading the rest out is a stable feature of the tax code.

Important Deductions for Landlords and Rental Property Owners

Owning rental property is often treated as a separate line of business for tax purposes. Landlords can typically deduct expenses that are directly connected to earning rental income. These deductions can offset rent received and help manage the tax impact of owning real estate.

1. Mortgage Interest, Property Taxes, and Insurance

For rental properties, three large recurring expenses are commonly deductible:

• Mortgage interest on loans secured by the rental property.
• Property taxes assessed by local governments on the rental real estate.
• Landlord insurance, including policies that cover damage to the building, liability claims, and loss of rental income in certain circumstances.

These are generally treated as operating expenses for rental activities, as long as the property is genuinely held for rent and not primarily for personal use.

2. Repairs, Maintenance, and Utilities

Keeping a rental property in good condition generates a variety of deductible costs. The IRS typically allows landlords to deduct ordinary repairs and maintenance in the year they are incurred, while improvements that add value or extend the property’s life may need to be capitalized and depreciated over time.

• Minor repairs such as fixing leaks, patching walls, or replacing broken fixtures.
• Routine maintenance like landscaping, cleaning common areas, or servicing heating and cooling systems.
• Utilities paid by the landlord, such as water, electricity, gas, or trash collection, if those costs are not separately billed to tenants.

To support these deductions, landlords should keep invoices, receipts, and records showing that the work was performed and paid for in connection with the rental property.

3. Management Fees and Professional Services

Landlords often hire third parties to help operate their properties. Fees paid to these providers are usually deductible as rental expenses:

• Property management companies that handle rent collection, tenant screening, and maintenance scheduling.
• Real estate agents involved in finding tenants or advising on lease terms.
• Legal and accounting fees related to leases, evictions, rental contracts, or tax preparation for the rental activity.

If you manage the property yourself, you cannot deduct the value of your own unpaid labor, but you can deduct out-of-pocket costs you incur while doing the work, such as supplies and mileage for property-related trips, subject to standard business rules.

4. Depreciation of Rental Buildings and Improvements

Unlike many business assets, real property is generally depreciated over a long period. Rental property owners may recover the cost of acquiring or constructing a building (excluding land), plus certain major improvements, through annual depreciation deductions.

Depreciation spreads the cost of the property over its useful life, which the tax code defines using established schedules. Because these rules are technical and require accurate basis calculations, many landlords work with tax professionals to apply the correct method and life to each asset.

5. Bad Debts and Unpaid Rent

Some landlords experience situations where tenants stop paying rent or vacate the property owing money. Whether and how you can deduct unpaid amounts depends on your accounting method and how the lease is structured.

In general, if you report rental income using an accrual method (recognizing income when it is earned rather than when paid), certain uncollectible rents may be treated as bad debts. To claim such a deduction, you typically must show that the amount has become worthless and that you took reasonable steps to collect it. Landlords using a cash method usually do not report rent until it is received, so there is no income to reverse if a tenant fails to pay.

Comparing Common Business vs. Rental Deductions

Recordkeeping: The Foundation of Every Deduction

Regardless of whether you run a business or own rental property, the strength of your deductions depends on your records. The IRS emphasizes that taxpayers must be able to substantiate expenses with documentation such as receipts, invoices, bank statements, mileage logs, and contracts.

Effective recordkeeping practices include:

• Maintaining separate bank accounts for business and rental activities.
• Saving digital and paper copies of invoices and receipts.
• Keeping mileage logs for business and rental-related driving.
• Tracking home office details, including square footage and the date the space began being used for business.
• Documenting the purpose of travel, meals, and entertainment expenses to show a direct business connection.

Good records make it easier to prepare accurate returns, respond to questions from tax authorities, and claim your full deductions without overlooking legitimate write-offs.

Frequently Asked Questions

Do I need to make a profit to claim business deductions?

No. You can typically claim ordinary and necessary business expenses even in years when you have a loss. However, if the IRS determines that your activity is a hobby rather than a business, different rules may apply.

Can I deduct my own salary as a sole proprietor?

As a sole proprietor, you do not pay yourself a salary in the same way you pay employees. Instead, your net profit after business deductions flows through to your personal tax return. The business cannot deduct a payment that is simply your own draw.

Are business meals still deductible?

Business meals with clients, prospects, or during business travel are generally deductible at a percentage of the cost, provided they are not lavish and have a clear business purpose. The exact percentage and any special rules may change over time, so check current IRS guidance when preparing your return.

How do I know if an improvement to my rental property is deductible immediately or must be depreciated?

Costs that keep the property in good working order are usually repairs and can be deducted in the year incurred. Expenses that add value, prolong the property’s life, or adapt it to a new use are often considered improvements and must be capitalized and depreciated. Because the rules are detailed, many landlords consult a tax professional for larger projects.

Can I deduct both home office expenses and rent on a separate office?

You may be able to deduct a home office if it is your principal place of business or where you conduct administrative or management activities, and you also rent other workspaces for specific purposes. The key is that each expense must meet IRS requirements and relate to genuine business use. Do not claim deductions for personal or mixed-use spaces that do not satisfy exclusivity rules.

Final Thoughts

Tax deductions for businesses and landlords are built into the tax system to recognize the costs involved in earning income. Understanding which expenses qualify, how to calculate them correctly, and what records to keep can help you lower your taxable income while staying compliant with tax rules. Because tax law changes over time and each situation is different, consider reviewing IRS publications or working with a qualified tax advisor before making major decisions.
