The core ways self-employed people get larger refunds

A bigger tax refund comes from either paying more tax during the year than you owe, or reducing the tax you owe by claiming deductions and credits you missed. For self-employed people, the second path is usually more realistic—most of you already underpay because quarterly estimated taxes are hard to calculate right. The first move is to find deductions you did not claim last year: home office space, vehicle mileage, equipment, software, professional services, and meals tied to business. The second is to check whether you missed tax credits like the Earned Income Tax Credit (EITC) or the Child and Dependent Care Credit. The third is to adjust your quarterly estimated tax payments so you do not overpay next year and waste money the government holds interest-free.

The math works like this: your refund is the total tax you paid (through quarterly estimates or withholding) minus the tax you actually owe. If you paid $8,000 in quarterly taxes but only owe $5,000, you get $3,000 back. To get a bigger refund without changing what you pay, you have to lower what you owe—which means finding deductions or credits the IRS allows but you did not claim.

Key Takeaways

  • Self-employed people can reduce their tax bill by claiming home office deductions, vehicle mileage, equipment, software, and professional services—all of which lower the refund you receive but increase the money you keep overall.
  • The Earned Income Tax Credit (EITC) and Child and Dependent Care Credit are refundable or partially refundable, meaning they can create a refund even if you owe no tax.
  • Adjusting your quarterly estimated tax payments based on actual income prevents overpaying and means you do not have to wait months for the IRS to return your money.
  • Keeping detailed records of mileage, home office square footage, and business expenses throughout the year makes claiming deductions faster and reduces audit risk.
  • A tax professional who works with self-employed people can often find deductions you missed in prior years and help you amend old returns to recover refunds.

Home office and workspace deductions

If you work from home, you can deduct either a simplified amount or your actual expenses. The simplified method lets you deduct $5 per square foot of dedicated workspace, up to 300 square feet ($1,500 maximum). This requires no receipts and takes one line on your return. The actual expense method requires you to measure the percentage of your home used for business, then deduct that same percentage of rent or mortgage interest, utilities, insurance, repairs, and depreciation. For most self-employed people, the simplified method is faster; for those with large dedicated spaces or high utility bills, actual expenses can be larger.

The key requirement is that the space must be used regularly and exclusively for business. A corner of your bedroom does not count; a spare room you use only for client meetings does. If you switched to working from home during 2020 or 2021 and never claimed the deduction, you can amend those returns using Form 1040-X to recover the refund.

Vehicle mileage and transportation costs

Self-employed people can deduct either the standard mileage rate or actual vehicle expenses. For 2024, the standard rate is 67 cents per business mile (this changes yearly). You track miles driven for business purposes—client visits, supply runs, travel to a separate office—and multiply by the rate. You do not deduct commuting from home to a regular workplace, but you do deduct miles to meet clients, attend conferences, or pick up materials.

If you use the actual expense method instead, you deduct a percentage of gas, insurance, maintenance, depreciation, and loan interest based on the percentage of miles driven for business. Most self-employed people find the standard rate simpler and often larger. Keep a mileage log or use a mileage-tracking app; the IRS accepts either, but a contemporaneous log (one you keep as you drive) is stronger than one reconstructed from memory months later. If you did not track mileage in prior years, you can still amend returns if you have reasonable records like calendar notes or credit card statements showing business trips.

Equipment, software, and professional services

Any equipment or software you buy for business is deductible. This includes computers, cameras, furniture, tools, accounting software, design tools, and subscriptions. Items under $2,500 can usually be deducted in full in the year you buy them (this is called the de minimis safe harbor). Larger items are depreciated over several years using Form 4562, but you can also use Section 179 expensing to deduct the full cost in year one, up to an annual limit (for 2024, the limit is $1,160,000, though most self-employed people will not hit it).

Professional services are also deductible: accounting fees, legal fees, bookkeeping, website design, marketing, and consulting. If you paid a CPA or bookkeeper last year, that fee is deductible. If you hired a contractor or freelancer, those payments are deductible (and you may need to issue them a 1099-NEC if you paid them over $600). Meals and entertainment tied to business are partially deductible—meals are 50% deductible (100% if they were provided during 2021 or 2022 under a temporary rule), and entertainment is generally not deductible unless it is a meal.

Tax credits that create refunds

Some tax credits are refundable, meaning they can give you money back even if you owe no tax. The Earned Income Tax Credit (EITC) is the largest. If you have low to moderate income and a may have access to child, you may receive $600 to $3,733 (amounts vary by income and number of children). You do not have to owe tax to receive it. The Child Tax Credit is $2,000 per child under 17, and up to $1,600 of it is refundable (the Additional Child Tax Credit). The American Opportunity Tax Credit for education is up to $2,500 per student, with up to $1,600 refundable.

Self-employed people often miss these because they assume credits only apply to employees. Check whether you have a may have access to child, whether your income falls within the EITC range (for 2024, up to roughly $63,398 for married filing jointly with three or more children), and whether you or a dependent attended college. If you missed claiming these in prior years, amending old returns can recover the refund.

Adjusting quarterly estimated taxes to avoid overpayment

Quarterly estimated taxes are due April 15, June 15, September 15, and January 15. Most self-employed people calculate them by taking last year's tax bill and dividing by four, then paying that amount each quarter. This works if your income is stable, but if your income dropped or you had a large deduction you did not account for, you overpay. The IRS holds the overpayment and returns it as a refund months later.

To avoid this, recalculate your estimate each quarter based on actual year-to-date income and expenses. If you earned $30,000 in the first quarter but expect to earn only $80,000 for the full year (not $120,000), your second-quarter estimate should be lower. You can also file your return early and pay any remaining balance, rather than making the January 15 estimate. This gets your refund sooner. Form 1040-ES walks you through the calculation, or a tax professional can do it for you.

Amending prior-year returns to recover missed refunds

If you did not claim deductions or credits in prior years, you can file an amended return using Form 1040-X. You have three years from the original due date to amend and recover a refund. For example, if you filed your 2021 return in April 2022, you can amend it until April 2025. The process is straightforward: file Form 1040-X showing the original numbers, the corrected numbers, and the reason for the change. Attach supporting schedules (like Schedule C with corrected business income and deductions) and mail it to the IRS address for your state.

The IRS typically processes amended returns in 16 weeks, though it can take longer if there are errors or if the return is selected for review. You can track the status using the IRS Where's My Amended Return tool on IRS.gov. If you are amending multiple years or have complex deductions, a tax professional can file the amendments and handle any IRS follow-up.

Working with a tax professional to find missed deductions

A CPA or tax professional who works with self-employed people can often find deductions you missed. They know which deductions are commonly overlooked—home office, vehicle mileage, professional development, insurance premiums, and health insurance deductions for self-employed people. They can also review your prior-year returns and identify amendments that would recover refunds. The cost of a consultation or return preparation is itself deductible, so it reduces your tax bill.

When you meet with a tax professional, bring records of all business expenses: receipts, invoices, bank statements, and mileage logs. If you do not have detailed records, bring what you have and ask what you can reconstruct. Many professionals offer a free initial consultation and can tell you in one call whether amending prior years makes sense for you.

Frequently Asked Questions

Can I claim a home office deduction if I also work in a separate office?

Yes, if you have a dedicated space at home used regularly for business. You cannot deduct both your home office and rent for a separate office, but you can deduct the home office if it is used for administrative work, client calls, or other business purposes separate from your main workspace.

What if I did not track mileage during the year?

You can still claim mileage on your current return if you can reconstruct it using calendars, credit card statements, or other records showing business trips. For prior years, the IRS is more skeptical of reconstructed logs, but you can still amend if you have reasonable documentation. Going forward, use a mileage app or keep a simple log in your car.

Do I have to choose between the standard mileage rate and actual expenses?

You can use the standard rate in one year and switch to actual expenses in a later year, but once you use actual expenses, you must continue using it for that vehicle in future years. Calculate both methods for your first year to see which is larger, then stick with it.

If I amend my return, will the IRS audit me?

Amending to claim legitimate deductions or credits does not increase audit risk. The IRS audits returns based on income level, industry, and the size of deductions relative to income. Claiming deductions you actually incurred is not a red flag. Keep receipts and records to support what you claim.

How long does it take to get a refund after I file?

The IRS typically issues refunds within 21 days of accepting your return if you file electronically and choose direct deposit. Paper returns take longer—up to eight weeks. Amended returns take roughly 16 weeks. You can check the status of your refund on IRS.gov using the Where's My Refund tool.
