Top Tax Deductions of 2025 Every Small Business Should Claim 

Are you sure you’re claiming all the tax deductions your business is entitled to?

As a business owner, it’s easy to assume that taxes are just something we need to accept and pay without much thought. But what if I told you that there are numerous opportunities to reduce your tax liability that you’re likely missing out on? 

Many business owners make the mistake of not understanding what expenses qualify for deductions or failing to track them properly, and this costs them far more than they realise.

I’ve seen businesses overpaying taxes because they didn’t know about certain deductions available to them or because they didn’t keep the right records. It’s not just about crunching numbers; it’s about understanding how to work with the system in your favor. 

So, let’s break down the most important tax deductions that can make a real difference for your business. From everyday expenses like office supplies to the less obvious ones like bad debts, every deduction counts. Stick with me through this guide, and I’ll show you exactly where you can save. 

Let’s get started.


1. Business Operating Expenses

Every small business owner needs to keep track of daily operating costs because these expenses are often fully deductible. These include rent for office space, utility bills, and office supplies. These regular expenses reduce your taxable income, lowering the amount of tax you owe.

The IRS allows businesses to deduct expenses directly related to operations. For example, if you’re renting office space, those rent payments are deductible, as well as utilities such as electricity, phone, and internet bills. Even if you work from home, a portion of your home’s expenses may be deductible through the home office deduction.

Here are a few points to keep in mind:

  • Rent: If you’re leasing a space for your business, this is a fully deductible cost.
  • Utilities: Deduct the portion of utilities used for business purposes, including phone, internet, and electricity.
  • Office Supplies: Stationery, printer ink, and other supplies that are used to run the business can be deducted.

Pro Tip:

If you work from home, you can deduct a portion of rent or mortgage interest, utilities, and even the cost of repairs, based on the square footage of your home office. According to the IRS, you can deduct $5 per square foot for the business area (up to 300 square feet).

2. Employee Wages and Benefits

Employee salaries, benefits, and other compensations are among the most significant business expenses. These payments can be deducted, which is why paying employees is not just an investment in your business but a way to reduce taxes.

The IRS lets you deduct all costs related to employees, including wages, health insurance premiums, and retirement contributions. For example, if you provide health insurance for your staff, the premiums you pay are deductible. Also, retirement plan contributions such as a 401(k) match or contributions to a SEP IRA are eligible for deduction.

Here’s what you need to keep in mind:

  • Salaries & Wages: Any money paid to employees, including overtime or bonuses, is deductible.
  • Employee Benefits: This includes insurance, retirement plan contributions, and other employee benefits that directly benefit your staff.
  • Payroll Taxes: Your portion of payroll taxes is deductible as well.

Pro Tip:

If you have a solo business, you can deduct 100% of your health insurance premiums. For companies with multiple employees, consider setting up a retirement plan like a SEP IRA, which also offers significant tax benefits. Check the IRS guidelines on deducting employee benefits to ensure you’re compliant.

3. Business Travel Expenses

Travel expenses for business are often deductible, so long as they are necessary for your work. This includes airfare, hotel stays, car rentals, meals, and other related expenses.

When you’re traveling for business, the IRS considers most of your expenses deductible as long as the trip is for business purposes. Meals are usually deductible at 50%, so keep track of all receipts. For transportation, keep detailed records of mileage or ticket costs.

Consider these points when claiming travel expenses:

  • Transportation: You can deduct the cost of airfare, taxi fares, and car rentals.
  • Meals & Entertainment: 50% of meals and entertainment during business travel can be deducted. However, they must be business-related.
  • Lodging: Deduct the cost of your hotel or accommodations during business trips.

Pro Tip:

For driving your own car for business, you can either deduct actual expenses or use the standard mileage rate (56 cents per mile in 2021). Keep a log to track mileage and document each trip.

4. Marketing and Advertising Costs

Marketing and advertising are essential to a business’s growth. The good news is that the IRS allows deductions for most of these costs. Whether it’s paying for social media ads, print ads, or creating a website, your marketing budget is an opportunity to lower your taxable income.

Marketing includes online ads, radio, print, and any other form of outreach. You can also deduct expenses for creating and maintaining your website, including hosting fees and website design costs.

Some key deductions to note:

  • Advertising: This includes online ads, print ads, and TV commercials.
  • Website Expenses: Costs for domain registration, hosting, and even website development can be deducted.
  • Marketing Materials: Flyers, brochures, and business cards are deductible.

Pro Tip:

Try to track and keep all receipts, including for online advertising and website management. Many marketing and advertising platforms, like Google Ads and Facebook Ads, offer reports that detail your spending, which can simplify the deduction process.

5. Depreciation of Assets

Depreciation is a tax break you can take advantage of for assets that lose value over time, like equipment or office furniture. Instead of deducting the entire purchase cost in one year, the IRS allows businesses to depreciate an asset over several years. This spreads out the deduction, but it still results in savings.

For example, if you buy a computer or office furniture, you can deduct a portion of the cost each year. The IRS uses specific methods to calculate depreciation, like the Modified Accelerated Cost Recovery System (MACRS), to determine how much of an asset’s value can be deducted each year.

Important things to note:

  • Computers & Office Equipment: Deduct the cost of computer hardware, software, and office equipment.
  • Furniture: Desks, chairs, and other office furnishings can be depreciated over time.
  • Vehicles: Depreciation for business vehicles is also deductible, but it’s subject to specific limits.

Pro Tip:

Use the IRS guidelines for depreciation schedules to determine how to break down asset costs. For large purchases, you may also be able to use Section 179, which allows businesses to deduct the full purchase price of qualifying equipment in the first year.

6. Business Insurance

Insurance is often an overlooked deduction. Business insurance premiums are generally tax-deductible, including general liability insurance, property insurance, and even workers’ compensation insurance. If you’re insuring your business assets, you can typically deduct the cost of these premiums.

Here’s what’s deductible:

  • General Liability Insurance: Coverage for business operations, including accidents, property damage, or legal costs.
  • Property Insurance: Insurance for business buildings and equipment.
  • Workers’ Compensation Insurance: Mandatory insurance in most states that provides benefits to employees in case of workplace injuries.

Pro Tip:

Don’t forget to check with your insurance provider to ensure your premiums are eligible for deductions. The IRS website also provides useful information about business insurance deductions.

7. Interest on Business Loans

If your business took out a loan for equipment, inventory, or expansion, you can deduct the interest you pay on that loan. Business loans can be a vital way to fund growth, and this tax break can help reduce the cost of borrowing.

Here’s what you can deduct:

  • Interest on Business Loans: If you took out a loan for your business, the interest on that loan is deductible.
  • Credit Card Interest: Interest paid on business-related credit cards can also be deducted.

Pro Tip:

Keep track of both principal and interest payments. Only the interest portion is deductible, not the principal.

8. Education and Training Costs

Business owners and their employees can deduct education and training expenses. Whether it’s learning a new skill or staying current with industry trends, the IRS allows these expenses as a deduction as long as they directly relate to your business.

  • Employee Training: Fees for training courses, seminars, and workshops for employees.
  • Self-Education: Courses or certifications you take as a business owner can be deducted.

Pro Tip:

Keep receipts for courses or seminars and be sure to document how they relate to your business. Check the IRS guidelines to ensure eligibility for educational deductions.

9. Business Meals

Business meals are deductible at 50% if they are directly related to your business activities. This can include meals with clients, partners, or employees, but they must meet certain criteria to be deductible. For example, the meal must take place during a business discussion or while traveling for business purposes.

Here are the essential points:

  • Client Meals: You can deduct 50% of the cost when dining with clients or business partners as part of a business meeting.
  • Meals During Business Travel: If you’re traveling for business, you can deduct 50% of the cost of meals while you’re away from home.
  • Entertainment Meals: If the meal is part of an entertainment activity, the entertainment portion may not be deductible, but the meal portion can be.

Pro Tip:

Keep detailed records of business meals, including the purpose of the meal and who was present. A simple receipt won’t be enough; you need to document the business purpose behind the meal for the IRS.

10. Bad Debts

If your business extends credit to customers and you end up unable to collect payment, you may be able to claim a deduction for bad debts. The IRS allows businesses to write off these debts as losses, reducing taxable income.

The general rules for bad debt deductions:

  • Accrual Method: If your business uses the accrual method of accounting, bad debts can be deducted.
  • Cash Method: If you use the cash method, bad debts aren’t typically deductible, since you’ve already recognized the income when it was earned.

Pro Tip:

For businesses using the accrual method, keep a list of the uncollected debts and provide evidence that you’ve made reasonable attempts to collect the funds. This is vital to ensure your deduction is accepted by the IRS.

11. Business Vehicle Expenses

If you use your personal vehicle for business, you can deduct the expenses associated with it. The IRS offers two ways to calculate vehicle deductions: the standard mileage rate and actual expenses.

  • Standard Mileage Rate: This is a simpler method where you can deduct a fixed amount per mile driven for business. For 2021, this rate was 56 cents per mile.
  • Actual Expenses: If you choose this method, you can deduct actual vehicle expenses, such as gas, maintenance, insurance, and depreciation.

Here are the types of expenses you can deduct:

  • Mileage: Deduct the miles driven for business purposes.
  • Fuel and Maintenance: Deduct costs for gas, oil, repairs, and maintenance.
  • Depreciation: You can depreciate the cost of your vehicle if it’s used for business.

Pro Tip:

Be sure to keep a detailed log of your business miles. The IRS recommends keeping track of the date, destination, purpose of the trip, and the number of miles driven.

12. Start-up Costs

Starting a business comes with various costs, many of which are tax-deductible. The IRS allows you to deduct certain business start-up expenses up to $5,000 in the first year of operation. However, if your costs exceed this amount, the remaining balance must be amortized over 15 years.

Eligible start-up costs include:

  • Legal Fees: Costs associated with setting up your business, such as incorporating or drafting contracts.
  • Market Research: Any expenses related to studying your market, including surveys or consulting.
  • Advertising: Pre-launch marketing campaigns and promotional materials for your business.

Pro Tip:

Be sure to keep all receipts for start-up expenses. If you’re nearing the $5,000 limit, consider spreading out some costs over future years to maximize your deductions.

13. Charitable Contributions

If your business makes charitable contributions, these can be deducted as well. The IRS allows businesses to deduct donations made to qualified 501(c)(3) organizations. This includes cash contributions as well as the fair market value of donated goods or services.

Key points to note:

  • Cash Donations: Deduct the full amount of cash donations made to eligible charities.
  • Donated Goods: If you donate equipment or supplies, you can deduct the fair market value of these goods.
  • Volunteer Expenses: In some cases, you can also deduct unreimbursed expenses incurred while volunteering for a qualified charity.

Pro Tip:

Make sure to keep receipts for all charitable donations and donations of goods. The IRS requires documentation for contributions above a certain threshold, so it’s crucial to keep detailed records.

14. Inventory Costs

If you sell physical goods, you need to track your inventory, as the costs associated with it can be deducted. This includes both the cost of goods sold (COGS) and the cost of maintaining inventory. For tax purposes, businesses are required to value their inventory at the end of each year.

Here’s how to manage inventory costs:

  • Inventory Purchases: Deduct the costs of purchasing goods for resale, including raw materials or finished products.
  • Inventory Shrinkage: If you experience inventory loss due to theft, damage, or obsolescence, this can also be deducted.
  • Storage Costs: The cost of storing inventory in a warehouse or storage facility is deductible.

Pro Tip:

Make sure to keep accurate records of all inventory transactions, including purchases, sales, and losses. The IRS requires businesses to report their inventory each year, so maintaining good records is essential for claiming these deductions.

15. Retirement Plan Contributions

Retirement plan contributions are a great way to save for the future while also reducing your taxable income. Whether it’s a 401(k), SEP IRA, or other retirement plan, the IRS allows businesses to deduct the contributions they make on behalf of their employees, including themselves as business owners.

Key deductions include:

  • Employer Contributions: If you contribute to your employees’ retirement plans, those contributions are deductible.
  • Self-Employed Contributions: As a self-employed individual, you can also contribute to your own retirement plan and deduct those contributions.

Pro Tip:

Consider setting up a retirement plan like a SEP IRA or a solo 401(k). These plans have higher contribution limits than traditional IRAs and allow you to save more for retirement while lowering your taxable income.

16. Licenses and Permits

Your business needs licenses and permits to legally operate, and the costs associated with them are deductible. These can include city, state, or federal licenses, permits related to health or safety regulations, and other required certificates.

Some key points:

  • Business Licenses: Costs for obtaining the necessary licenses for your industry or location.
  • Permits: Expenses for permits, such as health permits or building permits.
  • State & Local Fees: Fees for state and local business registration are also deductible.

Pro Tip:

Check the IRS guidelines for specific types of licenses and permits that are deductible. Some industries may have additional requirements, so be sure to consult with a tax professional to stay compliant.


Bottom Line
