Small business owners already wear many hats. Whether you're a freelancer, sole proprietor, or run an LLC, you're responsible for managing projects, meeting deadlines, and keeping clients happy. But once tax time rolls around, there's another hat to wear: the tax-saver.
Fortunately, the IRS (Internal Revenue Service) allows self-employed people to write off small business expenses list that help lower their taxable income. That means a smaller tax bill and more cash in your bank account. But many taxpayers miss out on these savings because they don’t know which new business tax deductions apply to them or how to claim them correctly.
In this article, we’ll explore what small business deductions are and how they work. We will also explore small business deductible expenses that you should never overlook and some tips to maximize write-offs and keep more of your business income
What Are Small Business Deductions?
Small business deductions are legitimate business-related expenses that you can subtract from your gross income to reduce your income tax. The IRS allows self-employed individuals to deduct expenses that are considered both ordinary and necessary to operate their business.
But what does that actually mean? An ordinary expense is common and accepted in your field. For example, a photographer buying editing software or a freelance writer subscribing to grammar tools. However, a necessary expense is helpful and appropriate for your business. It doesn’t need to be essential, just useful to your daily work.
Let’s say you’re a freelance designer, and you pay for Adobe Creative Cloud. That’s both ordinary (designers typically use it) and necessary (you need it to deliver your work). So, it's deductible.
Here are some common self-employed professions that qualify for these small business deductions:
- Freelance writers, editors, and designers
- Independent consultants and coaches
- Real estate agents
- Rideshare and delivery drivers
- Online sellers or eCommerce store owners
- Makeup artists, photographers, or videographers
- Handymen, electricians, or independent contractors
- Tutors or online course creators
- Home-based bakers or event planners
Let’s take an easy example, if you earned $85,000 in business income as a sole proprietor, and spent $20,000 on office supplies, a business trip, travel expenses, vehicle expenses, and health insurance premiums, then only $65,000 counts as your taxable income.
You’ll usually report this on Schedule C of your tax return if you operate as a sole proprietorship, independent contractor, or single-member LLC. This helps you determine your qualified business income and small business tax owed.
Small Business Deductions That Deserve Your Attention
If you're self-employed, missing out on standard deductions is like walking away from money that’s legally yours. The IRS gives you several ways to reduce your taxable income, if you know where to look. Below are some of the most overlooked but powerful small business deductions for self-employed business owners.
Home Office Deduction
Do you work from a spare bedroom, garage studio, or corner desk in your apartment? If you use a portion of your home exclusively and regularly for business, you can claim a home office deduction.
There are two ways to calculate your home office expenses:
- Simplified method: Deduct $5 per square foot, up to 300 square feet.
- Actual expenses method: Deduct a portion of your rent/mortgage, utilities, mortgage interest, property taxes, and repairs based on your office’s square footage.
Even your home internet, electricity, and renter’s insurance may qualify for small business deductions, if they support your business directly. This is especially important for sole proprietors working in dedicated office space within their homes.
Vehicle and Business Travel Expenses
Do you drive your car for business meetings, deliveries, or site visits? You can deduct vehicle expenses or car expenses like gas, maintenance, insurance, and car depreciation. These small business travel expenses can be calculated either by using the actual cost method or the standard mileage rate (67 cents per mile in 2024).
Business travel outside your city, such as for trade shows or client meetings, is also considered a small business deduction. This includes:
- Flights and hotels
- Business Meals (up to 50% of the cost)
- Tolls, parking, and registration fees
Even cell phone use during a business trip can count as a deductible if used for work-related calls. Keep a mileage log or use an app like MileIQ for accurate tracking.
Office Supplies and Depreciation
Everyday items like pens, notebooks, printer ink, and software subscriptions ordinary and necessary expenses that you can fully deduct in the year you buy them. If you purchase equipment like a laptop or desk, you may be able to:
- Deduct the full cost using Section 179, or
- Spread the cost over several years through depreciation
These small business deductions help reduce your federal tax and increase accuracy in your business tax calculations. Make sure you’re only deducting items used for business purposes, not personal expenses.
Self-Employment Tax Deduction
As a self-employed person, you pay 15.3% in Social Security and Medicare taxes, both the employer and employee share. This is referred to as self-employment tax.
But here’s the silver lining: you can half of that amount of this small business deduction on your personal tax return, even if you don’t itemize. This deduction reduces your adjusted gross income and overall tax liability.
Health Insurance Premiums
If you’re self-employed and pay for your own health plan, you can deduct health insurance premiums for yourself, your spouse, and dependents. This includes medical, dental, and qualified long-term care plans.
Premiums paid for coverage under retirement accounts may also be considered. To qualify, you must not be eligible for another employer-subsidized plan, even through a spouse.
Startup Costs
Starting a business involves upfront investments, from logo design to business registration. The IRS allows you to deduct up to $5,000 in startup costs in the first year, and up to $5,000 in organizational costs in your first year of operation.
These business-related expenses are especially useful for new businesses looking to reduce their early tax rate and gain small business tax advantages. Any remaining balance must be spread out over 15 years through amortization.
Retirement Contributions
Contributions to tax-advantaged retirement plans help you save for the future while trimming down your taxable income today. Self-employed individuals can contribute to:
- SEP IRA
- Solo 401(k)
- Traditional IRA
These plans can offer generous limits, especially if you had a good income year. Contributions made before the filing deadline often apply to the previous tax year.
Educational Expenses
Courses, webinars, books, or training programs that enhance your current skills or credentials may be deductible, but only if they relate directly to your current business.
The IRS requires educational expenses to improve or maintain skills required for your present work and does not qualify you for a new occupation.
Tips to Maximize Your Small Business Deductions
Knowing about small business deductions is only half the work. The other half is making sure you actually claim them the right way. Many self-employed people leave money behind simply because they’re not keeping records or tracking what counts.
These tips can help you stay organized and reduce your tax liability without the last-minute scramble.
Separate Personal and Business Finances
Mixing personal and business money creates confusion and complications. Set up a separate bank account and business credit card. This makes tracking business use easier and keeps you ready for tax season or an audit.
Track Every Expense in Real Time
Use software or spreadsheets to track every business-related expense. Small costs like Zoom subscriptions or tolls on a business trip add up fast. Good recordkeeping ensures you're ready for accurate tax preparation.
Understand Your Business Structure
Your business entity such as sole proprietorship, LLC, or partnership, determines your filing method and tax forms. Sole proprietors and LLCs usually file Schedule C, while partnerships use Form 1065.
Pay Estimated Taxes Quarterly
If you expect to owe $1,000 or more, make quarterly tax payments. Use IRS Form 1040-ES and avoid last-minute surprises.
Save for Retirement Before the Deadline
You can contribute to retirement accounts like SEP IRA or Solo 401 even after the tax year ends, as long as it's before the filing deadline. These accounts offer major tax breaks.
Log Vehicle and Mileage Carefully
Whether you deduct actual expenses or use the standard mileage rate, accurate logs are essential. Keep dates, business purpose, and miles.
Work With a Tax Professional
A CPA or tax professional understands complex deductions, can help lower your tax liability, and ensures your tax return is audit-proof. Their fee? Also deductible under tax preparation services.
Review Before You File
Go over every line of your return. Compare it with last year, check all deductions, and make sure you've claimed every qualified business income credit or deduction available. Consider all business-related expenses and tax credits that apply to self-employed people.
Final Thoughts
Paying taxes is part of the job, but overpaying isn’t. For small business owners, understanding and maximizing tax write-offs is one of the smartest moves you can make. These small business deductions exist to support your hustle, not to complicate it.
Whether you’re a sole proprietorship offering consulting services, an independent contractor managing multiple clients, or a small LLC starting out with limited capital, the savings are real. Start early. Track often. Ask for help when needed. And make sure every necessary expense gets counted, because it all adds up.
Your time is valuable, so are your small business deductions. Start making both work, for your business today.
