Small-business tax deductions, or write-offs, decrease your taxable income. This can lower your business’s tax bill.
If you plan to claim deductions, make sure to keep detailed records. Doing so throughout the year can help you avoid IRS audits. Accounting software can help automate this process.
Here are 24 small-business tax deductions that can help you save money.
Most apply to sole proprietorships, corporations, LLCs and partnerships. But we also recommend finding a small-business tax advisor to double-check your eligibility.

What’s new with business tax deductions in 2026?

The passage of the "big, beautiful bill" in July 2025 changed several tax laws for business owners. Here's a rundown of the biggest updates.
  • Permanent QBI deduction. Sole proprietorships, partnerships, S corporations and certain LLCs can continue to deduct up to 20% of their qualified business income. Previously, the deduction was supposed to expire following the 2025 tax year.
  • No tax on tips. Self-employed business owners who receive tips can now deduct them.
  • Higher Section 179 expense limit. This deduction limit rose from $1.22 million in 2024 to $2.5 million in 2025 and $2.56 million in 2026. Section 179 lets you immediately deduct qualifying equipment purchases as opposed to depreciating them over time. 
  • Ability to immediately deduct R&D expenses. Businesses no longer need to amortize research and development expenses. 
  • Higher interest deduction limit. Businesses can now factor depreciation and amortization into their adjusted taxable income calculation. This increases how much they can claim in business interest deductions.
  • Bonus depreciation. Businesses can deduct the entire cost of property bought after Jan. 19, 2025.

1. Startup and organizational costs

Who it applies to: Businesses with startup expenses from before they became operational.
Deduction amount: You may be able to write-off up to $10,000 immediately. But it depends on how much you spent.
  • If you spent less than $50,000 in startup or organizational costs, respectively. You can deduct up to $5,000 in each for your first year of operation. Then, you amortize (or evenly spread out) the remaining costs over 180 months.
  • If you spent more than $50,000 (but less than $55,000) in either category. Those maximums phase out dollar-for-dollar. For instance, if you spent $52,000 on startup costs, you could take an immediate $3,000 deduction (5,000 - 2,000). Then, you’d amortize the remaining $49,000 (52,000 - 3,000) over 180 months.
  • If your expenses exceed $55,000 in either category. You lose that immediate deduction. Instead, you need to amortize the entire expense over 180 months. 
Examples of startup costs:
  • Advertising.
  • Market research. 
  • Consulting.
  • Employee training. 
Examples of organizational costs:
  • Legal services for forming a corporation or LLC.  
  • Accounting services.
  • Document drafting.  
Limitations: Typically, organizational costs don’t apply to sole proprietorships. And you can only deduct startup costs if your business actually opens. Expenses from after you open your doors don’t qualify as startup costs.
🤓 Nerdy Tip
Unsure if an expense qualifies for a deduction? The IRS says every business expense you deduct must be “both ordinary and necessary.” That means it’s a common expense in your industry and helpful to your business.

2. Cost of goods sold

Who it applies to: Businesses that resell or manufacture items.
Deduction amount: Up to 100%. You’ll need to value your inventory at the beginning and end of each tax year to figure your cost of goods sold.
Examples of what can factor into cost of goods sold:
  • Raw materials.
  • Items that you resell.  
  • Direct labor (for manufacturing products you sell). 
  • Storage. 
  • Packaging. 
Limitations: Cost of goods sold excludes indirect expenses for things like marketing and legal assistance. See our explainer on the cost of goods sold for more tips on what to include while calculating it.
Additionally, personal service businesses typically can’t take this deduction.

3. Home office

Who it applies to: Entrepreneurs who have dedicated offices in their living space.
Deduction amount: $5 per square foot (up to $1,500). You can also calculate it as the percentage of space your home office occupies multiplied by all qualifying home expenses.
Examples:
  • Rent or mortgage payments. 
  • Mortgage interest. 
  • Utilities. 
  • Home insurance. 
  • Repairs and maintenance. 
Calculation methods:
1. The simplified method: Deduct $5 per square foot of office space up to $1,500. 
2. The regular method: Multiply the percentage of space your home office occupies by your total qualified home expenses. For instance, let’s say your monthly home expenses add up to $3,500. And your home office occupies 200 square feet of your 2,000 square foot home. Since your home office takes up 10% of your home (200 / 2,000), you’d deduct $350 (3,500 * 0.1).
Limitations: To qualify, you must use the office regularly and exclusively for business purposes.

4. Qualified business income

Who it applies to: Most sole proprietorships, partnerships and S corporations. Certain LLCs.
Deduction amount: Up to 20% of your qualified business income.
Examples of what factors into qualified business income:
  • Net amount of “qualified items of income, gain, deduction and loss” from qualified businesses, according to the IRS. 
  • Deductible portion of self-employment tax. 
  • Deductible portion of self-employed health insurance. 
  • Deductions for retirement plan contributions. 
Limitations: This deduction typically isn’t available to C corporations. Additionally, the percentage you can deduct varies depending on how much you make.
In 2026, for example, you qualify for the full 20% deduction if you make less than $201,751 in taxable income. See our article on the qualified business income deduction for more details on who qualifies.
Capital gains and losses, dividends and interest income don’t count toward qualified business income.
LLCs are only eligible if they file taxes as a partnership, S corp or sole prop.

5. Utilities

Who it applies to: Entrepreneurs who run their business out of a brick-and-mortar location or rented office space.
Deduction amount: Up to 100%.
Examples:
  • Gas and electricity. 
  • Trash and recycling. 
  • Internet and phone. 
  • Water and sewage. 
Limitations: You must use the space regularly and exclusively for business purposes. If you run your business from a home office, see the home office deduction.

6. Insurance

Who it applies to: Businesses that pay insurance premiums.
Deduction amount: Up to 100%.
Examples of eligible insurance premiums:
Limitations: Not every policy is eligible. For instance, you can’t deduct insurance premiums for loss of earnings due to sickness or disability. The same generally goes for your life insurance policy. See the IRS’ list of nondeductible premiums for more details.

7. Business property rent

Who it applies to: Businesses that operate out of rented properties.
Deduction amount: Up to 100%.
Examples:
  • Rented office space. 
  • Rented retail space. 
  • Rented workspaces. 
  • Rented warehouses for production. 
Limitations: Business owners can’t deduct these expenses if they plan to receive equity in the property. You may also be ineligible if your landlord is a close relative and is giving you a deal. If you run your business out of a home office, see the home office deduction for more information.

8. Auto expenses or mileage

Who it applies to: Entrepreneurs who drive for business purposes.
Deduction amount: 72.5 cents per mile driven for business use or up to 100% of business auto expenses.
Examples:
  • Mileage driven for business purposes. 
Or:
  • Business vehicle purchases. 
  • Business vehicle maintenance and repair. 
  • Business vehicle insurance and registration. 
  • Business vehicle parking fees. 
  • Business vehicle garage rental.
Calculation methods:
1. Calculate actual expenses. This means you deduct the actual expenses related to operating and maintaining your business vehicle. If the business purchased the vehicle during the same tax year, you might have to depreciate its value. That means you spread the deductions out over multiple years. 
Let’s say you use the car for business and personal purposes, though. In this case, you need to figure out what percentage of your mileage went toward business travel. Then, you multiply that percentage by the associated vehicle expenses.
2. Use standard mileage rate. The IRS’ standard mileage rate for self-employed individuals and businesses in 2026 is 72.5 cents per mile. For example, if you drove 2,000 miles over the tax year for work purposes, you’d deduct $1,450 (2,000 * 0.725).  
Limitations: You can’t use the standard mileage rate in certain instances. For example, if you operate five or more vehicles at the same time, you’ll need to calculate your actual expenses to deduct them.

9. Equipment and machinery

Who it applies to: Businesses that buy equipment and/or machinery.
Deduction amount: Up to 100%. But you usually need to depreciate equipment you plan to use for more than a year. See our depreciation explainer for more information on calculating this value.
However, the OBB expanded the list of equipment that qualifies for immediate 100% deductions. For more details, see our article on how Section 179 works.
Examples:
  • Office equipment, like printers. 
  • Business computers.
  • Heavy machinery.
Limitations: You can only depreciate business equipment if you own it and it has a determinable useful life. You must also expect it to last for more than a year.
Your Section 179 deductions cannot exceed $2,560,000 in 2026. This applies to expenses you deduct immediately as opposed to depreciating over time.

10. Office supplies and furniture

Who it applies to: Businesses that use office supplies and furniture to support their operations.
Deduction amount: Up to 100%.
Examples:
  • Paper. 
  • Boxes. 
  • Pens. 
  • Staples. 
  • Chairs. 
  • Desks. 
Limitations: If any of your supplies are useful for more than a year and qualify as capital assets, you must depreciate them instead of immediately taking the full deduction.

Where do you claim small-business tax deductions?

The tax forms you use to claim small-business tax deductions vary depending on your business’s structure. Here’s a breakdown:
  • Sole proprietorships: Schedule C (Form 1040). 
  • Partnerships: Form 1065
  • C corporations:  Form 1120. 
  • S corporations: Form 1120-S. 
LLC isn’t an official tax classification. Instead, the IRS typically taxes single-member LLCs as sole proprietorships and multi-member LLCs as partnerships.

What’s the difference between a tax deduction and a tax credit?

Tax deductions decrease your taxable income, whereas tax credits decrease your tax bill. Both minimize how much you pay in taxes — just in different ways.
Let’s say you’re a sole proprietor with an income of $110,000. You take $7,000 in tax deductions, which brings your taxable income to $103,000. This bumps you down to a lower tax bracket (where you owe 22% vs. 24% in federal income taxes).
Without tax credits, you’d owe $22,660 (0.22 * 103,000) in federal income taxes. But let’s say you actually qualify for $2,000 in tax credits. That would bring your tax bill down to $20,660 (22,660 - 2,000).
