You're self-employed, you work hard for your money, and you keep hearing that business owners can write off practically everything. But what can you actually deduct on your taxes?
If you've spent any time on social media, you've probably seen someone claim that buying a vehicle, taking a vacation, or paying for lunch becomes a tax write-off as soon as you start a business.
Unfortunately, that's not how it works.
But here's the other side of the problem: Some self-employed taxpayers are so afraid of claiming the wrong deductions that they overlook legitimate business expenses that could reduce their taxable income.
After approximately 10 years of preparing tax returns, I've encountered both situations.
The goal isn't to claim everything you spend money on. It's to understand which expenses are legally deductible, how to document them, and how to avoid costly mistakes.
Whether you're a freelancer, DoorDash driver, independent contractor, consultant, or small-business owner, this guide will help you understand common self-employed tax deductions.
This article discusses 2026 business expenses, generally reported on tax returns filed in 2027. Where relevant, we'll also distinguish the rules for 2025 returns filed in 2026.
The IRS generally allows business owners to deduct expenses that are ordinary and necessary for operating their trade or business.
An ordinary expense is common and accepted in your line of work.
A necessary expense is helpful and appropriate for your business. It doesn't necessarily have to be indispensable.
For example, a delivery driver might deduct qualifying vehicle expenses, while a graphic designer might deduct business-related design software.
But just because something is useful doesn't automatically make it deductible.
The expense must have a legitimate business purpose, and personal expenses generally cannot be deducted as business expenses.
Paying for something with your business debit card doesn't change that rule.
Most sole proprietors report business income and expenses on Schedule C, which is filed with their individual federal income tax return.
If you use your personal vehicle for business, your mileage may be one of your largest deductions.
This is particularly important for DoorDash, Uber Eats, Spark, Instacart, rideshare drivers, and other independent contractors who spend substantial time driving.
For 2026, the IRS business standard mileage rates are:
January 1–June 30, 2026: 72.5 cents per qualifying business mile.
July 1–December 31, 2026: 76 cents per qualifying business mile.
For comparison, the business mileage rate for 2025 was 70 cents per mile.
Imagine you drove 15,000 qualifying business miles during the second half of 2026.
At 76 cents per mile, your potential standard mileage deduction would be:
15,000 × $0.76 = $11,400
That's an $11,400 business deduction—not an $11,400 tax refund.
Your actual tax savings depend on your overall tax situation.
Qualifying business travel may include driving between business locations, traveling to meet clients, or making deliveries.
However, ordinary commuting between your home and regular workplace generally isn't deductible.
The rules can become more complicated when your home qualifies as your principal place of business.
Maintain a mileage log showing the date, destination, business purpose, and miles driven. You should also keep appropriate records of total annual mileage.
Apps can help track trips, but you're still responsible for making sure the information is accurate.
Important: The standard mileage method and actual vehicle expense method have different requirements. You generally cannot deduct both the standard mileage rate and the same vehicle's actual operating costs for the same business use.
This is one of the most misunderstood business deductions.
No, you generally cannot simply deduct your entire monthly car payment because you use the vehicle for business.
Vehicle deductions depend on factors such as whether you own or lease the vehicle, the business-use percentage, and the deduction method you qualify to use.
For an owned vehicle, the principal portion of a loan payment generally isn't deductible as a business expense. Instead, the vehicle's cost may be recovered through applicable depreciation rules.
Qualifying business-use loan interest may be separately deductible, subject to applicable rules.
If you use the standard mileage method, that rate already accounts for certain vehicle operating costs.
And if you use your vehicle for both personal and business purposes, only the qualifying business portion of applicable expenses may be deductible.
The lesson?
Buying a vehicle doesn't automatically make the entire purchase a tax write-off.
Possibly.
If you're self-employed and use part of your home regularly and exclusively for qualifying business activities, you may be eligible for a home office deduction.
For example, imagine you operate a virtual consulting business and have a dedicated room used exclusively for business.
Depending on your circumstances, you may qualify to deduct certain home office expenses.
There are generally two methods.
The simplified method generally allows $5 per square foot of qualifying business-use space, up to 300 square feet.
That means a maximum simplified deduction of $1,500.
The actual expense method generally involves calculating the business portion of eligible expenses such as rent, utilities, insurance, and certain repairs.
Additional rules apply to homeowners, including depreciation considerations.
Using your kitchen table to occasionally answer business emails generally won't satisfy the exclusive-use requirement.
Likewise, a bedroom used for both sleeping and business usually doesn't qualify in its entirety.
There are limited exceptions to the exclusive-use requirement, such as certain inventory storage and daycare situations.
A home office deduction isn't based simply on working from home. It's based on meeting the applicable IRS requirements.
If you use your phone or internet connection for business, you may be able to deduct the qualifying business portion of those expenses.
Let's say your monthly phone bill is $100 and you can reasonably substantiate that 60% of its use is business-related.
Your potential business deduction would be approximately $60 per month.
But you generally can't deduct the entire bill when you also use the service personally.
The same principle applies to internet service.
For example, someone operating an online business may use internet access for client communications, uploading documents, and managing business software.
A reasonable, supportable allocation between business and personal use is important.
Many self-employed taxpayers overlook smaller recurring expenses.
Depending on your business, deductible costs may include office supplies, postage, printer ink, business-related subscriptions, website hosting, bookkeeping software, and other ordinary and necessary expenses.
Larger equipment purchases may be subject to depreciation rules, Section 179 expensing, or other applicable provisions.
For example, a self-employed photographer may need cameras and editing software, while a virtual assistant may need a computer and productivity subscriptions.
The key is documenting the purchase and establishing its business purpose.
Not every equipment purchase is automatically deductible in full during the year it was purchased.
If you're spending money to attract customers, those expenses may qualify as business deductions.
Common examples include paid social media advertisements, business cards, website advertising, promotional materials, and qualifying marketing services.
For example, if you spend $200 on Facebook advertisements promoting your business, that may be an ordinary and necessary advertising expense.
However, special rules can apply to certain promotional costs, gifts, and other expenditures.
The important distinction is whether the expense genuinely relates to promoting or operating your business.
You've probably seen someone online claim that business owners can write off vacations simply by discussing business during the trip.
That's not how business travel deductions work.
Qualifying business travel must have a legitimate business purpose and satisfy applicable tax requirements.
Travel expenses may include eligible transportation, lodging, and certain other costs while away from your tax home for business.
Business meals are generally subject to a 50% deduction limitation, with exceptions for certain situations.
Personal vacation expenses generally aren't deductible.
If a trip combines business and personal activities, expenses may need to be allocated under applicable rules.
Taking a laptop on vacation doesn't automatically turn the entire trip into a business expense.
And eating lunch while working doesn't automatically make your meal deductible.
Some self-employed individuals may qualify for a deduction for eligible health insurance premiums.
This deduction can potentially include qualifying medical, dental, and certain long-term care insurance premiums.
However, eligibility is subject to several rules, including earned income limitations and restrictions involving eligibility for employer-subsidized coverage.
The self-employed health insurance deduction is generally claimed as an adjustment to income rather than as an ordinary Schedule C expense.
This is an example of why understanding where a deduction belongs on your return matters just as much as knowing it exists.
Self-employed individuals generally pay self-employment tax on qualifying net earnings in addition to any applicable federal income tax.
The combined Social Security and Medicare self-employment tax rate is generally 15.3%, subject to applicable wage-base limitations and other rules.
For many sole proprietors, properly deductible business expenses reduce net business profit, which may also reduce net earnings subject to self-employment tax.
But here's something important:
A $1,000 tax deduction does not mean you receive $1,000 back from the IRS.
A deduction reduces income used in calculating taxes. A tax credit, by contrast, generally reduces tax liability directly, subject to its specific rules.
Understanding that distinction can help you avoid unrealistic expectations about business write-offs.
This is especially important for gig workers, freelancers, and people who receive payments directly from customers.
Not receiving a 1099 doesn't automatically mean the income is tax-free.
Generally, taxable business income must be reported whether or not you receive an information return.
For example, if customers paid you directly for cleaning services, landscaping, consulting, or other work, that income may still need to be reported.
The same applies to cash payments.
Your tax reporting obligations depend on the nature of the income, not simply whether someone issued you a tax form.
And when determining whether you must file, self-employment income has additional rules. Individuals with $400 or more in net earnings from self-employment generally must file a federal income tax return, even when their total income is below the standard filing threshold, subject to applicable exceptions.
Some mistakes are easy to make when you're preparing your own business return.
Claiming personal expenses as business expenses.
A purchase doesn't become deductible simply because it was paid from your business account.
Failing to track business mileage.
Without adequate records, substantiating a vehicle deduction can become difficult.
Assuming every business purchase is immediately deductible.
Some assets are subject to depreciation or other special rules.
Not reporting income because no 1099 was received.
Taxable business income generally must be reported regardless of whether an information return was issued.
Mixing personal and business finances.
Although a separate bank account isn't universally required for sole proprietors, keeping business transactions separate can make bookkeeping and recordkeeping substantially easier.
Forgetting about estimated taxes.
Many self-employed taxpayers must make estimated tax payments during the year, depending on their expected liability and other payments.
Not every self-employed taxpayer needs professional preparation.
If your business is straightforward, you maintain accurate records, and you're comfortable applying the tax rules, preparing your own return may be reasonable.
But as your business grows, your tax situation may become more complicated.
For example, you might purchase equipment, hire subcontractors, operate in multiple states, acquire rental property, or begin making retirement contributions through a self-employed retirement plan.
A tax professional can help you understand the tax treatment of these transactions and identify deductions you're legally entitled to claim.
At Precision Tax Services Group, I believe tax preparation should involve more than entering numbers into software.
With approximately 10 years of tax preparation experience, I take a personalized approach to reviewing income, expenses, and the information clients provide.
My goal is to help clients prepare accurate returns, understand their tax obligations, and avoid overlooking legitimate deductions.
Potentially, yes. Qualifying expenses may be deductible even when a business has relatively little income. However, the IRS distinguishes businesses from activities not engaged in for profit, and losses can be subject to additional limitations.
Yes, qualifying expenses related to a separate self-employed business may be deductible even if you also have W-2 employment income.
Ordinary everyday clothing generally isn't deductible simply because you wear it while working. Certain protective clothing or required uniforms that aren't suitable for ordinary wear may qualify.
Generally, only the qualifying business-use portion is deductible when the phone is used for both personal and business purposes.
You must maintain records sufficient to substantiate your deductions. Specific documentation requirements vary by expense, and certain expenses, including travel and vehicle use, have stricter substantiation rules.
The portion of qualifying tax preparation fees attributable to your business may generally be deductible as a business expense. Personal tax preparation costs are treated differently.
Being self-employed gives you flexibility, but it also means taking responsibility for tracking income, documenting expenses, and understanding your tax obligations.
