Common Self-Employed Tax Deductions
If you work for yourself, some normal business costs may reduce your taxable profit. The hard part is knowing what usually counts, what records you need, and where people make expensive mistakes.
The short answer
Self-employed tax deductions are usually ordinary and necessary business expenses. In plain English, that means costs that are common for your type of work and helpful for running the business.
A few examples many self-employed people ask about:
- Home office
- Phone and internet used for work
- Software and subscriptions
- Business insurance
- Mileage and car expenses for business driving
- Supplies, postage, and shipping
- Advertising and website costs
- Professional fees, including accounting help
- Health insurance in some situations
- Retirement contributions in some situations
But there is an important truth: not every expense is fully deductible, and not every deductible expense works the same way. Some costs must be split between personal and business use. Some are limited. Some depend on how your business is set up and how good your records are.
That is why many people choose to talk to a licensed CPA or IRS Enrolled Agent before filing. If you want help comparing options, BalancedRow can help you get matched with a licensed accountant at no cost to you. We are a free matching service, not an accounting firm, and we do not give tax advice.
Common deductions self-employed people often ask about
Here are categories that often come up. These are general examples, not advice, and the real tax treatment depends on your situation, records, and location.
1. Home office
You may be able to deduct part of your home costs if you use part of your home regularly and exclusively for business. That word exclusively matters. A kitchen table used for both dinner and work is where many people get into trouble.
Home office questions often involve:
- Rent or mortgage interest
- Utilities
- Renter's or homeowner's insurance
- Repairs
- Square footage used for business
2. Car and mileage
If you drive for work, business miles may matter. Commuting from home to a regular office is usually different from driving between clients, job sites, or the post office for business tasks. Good mileage logs matter a lot.
Keep track of:
- Date
- Where you went
- Business purpose
- Miles driven
3. Phone and internet
If you use your phone or internet for both personal and business reasons, the business part may be the part that counts. A dedicated business line is usually easier to document than a shared family plan.
4. Supplies, equipment, and software
Think printer ink, office supplies, tools, industry software, cloud storage, video meeting software, and payment-processing tools. Some purchases are simple current expenses. Others may need different treatment depending on cost and use.
5. Marketing and sales costs
This can include:
- Website hosting
- Domain name
- Online ads
- Design work
- Business cards
- Email marketing tools
6. Education and professional services
Training that maintains or improves your current business skills may be treated differently from education for a completely new career. Professional fees can also matter, such as bookkeeping, tax preparation, payroll support, or legal document review.
If your records are messy, it may help to first understand bookkeeping before tax season gets close.
7. Health insurance and retirement
These can be valuable areas, but they are also easy to misunderstand. The rules often depend on business income, other coverage available to you, and how your business is structured. This is a smart place to slow down and get licensed help.
Where people get burned
Most self-employed tax problems do not start with bad intentions. They start with guessing.
Here are common mistakes:
1. Writing off personal expenses as business expenses
A new laptop for mixed home use, family cell phone plans, clothes that are not true work uniforms, and meals without a clear business purpose are common problem areas.
2. No proof
A bank statement alone is not always enough. Keep receipts, invoices, mileage logs, and notes about the business purpose.
3. Mixing business and personal money
Using one account for everything creates confusion fast. A separate business checking account can make tax time much easier.
4. Forgetting self-employment tax
Many people focus only on income tax and forget Social Security and Medicare taxes that self-employed workers often owe.
5. Ignoring quarterly estimated taxes
If no tax is withheld from your income, waiting until April can lead to a painful bill and possible penalties.
6. Assuming a friend, online post, or social media video is correct
Tax rules change. What worked for someone else may not fit your facts.
7. Sharing sensitive information too early
Never send your Social Security Number, ITIN number, bank login, or tax documents to someone you have not verified. BalancedRow only collects your contact information and request details for matching. We do not ask for SSNs, ITIN numbers, financial-account numbers, or tax documents.

What records help the most
You do not need perfect books on day one. But you do need a system.
A simple recordkeeping setup usually includes:
- A separate business bank account
- A business credit card when possible
- Monthly downloads of bank and card statements
- A folder for receipts and invoices
- A mileage log if you drive for work
- A list of major purchases and when you started using them for business
- Copies of prior tax returns
Good records can save you money in two ways.
First, they help a licensed accountant identify expenses you may have missed. Second, they reduce cleanup work, which may reduce your total fee.
Typical fee ranges are just that, ranges. An individual tax return often runs about $180-$500. A small-business return often runs about $500-$1,800. Monthly bookkeeping often runs about $150-$600 per month depending on transaction volume. An hourly CPA often runs about $150-$400 per hour. The real fee depends on the work involved, your situation, the records you bring, and your area.
Before hiring anyone, ask for the fee and scope in writing. You can also review general pricing so the numbers you hear feel more familiar.
What to do next
If you are self-employed and want to handle this the safe way, use this checklist:
- List your real business expenses from the last year.
- Separate personal and business use for mixed expenses like phone, car, and internet.
- Gather proof such as receipts, statements, and mileage records.
- Write down your questions before speaking to anyone.
- Hire a licensed accountant such as a CPA or IRS Enrolled Agent for advice on your specific facts.
- Verify the credential and PTIN yourself using the IRS Directory of Federal Tax Return Preparers and, for CPAs, your state board of accountancy.
- Confirm the fee and scope in writing before any work starts.
If English is not your first language, or you file with an ITIN, getting help is still normal and safe. You are not the only one. You can keep control of the process: you compare, you verify, you choose who to hire, and you keep your sensitive documents until you have verified who you are dealing with.
If you want help finding someone who works with self-employed taxpayers, immigrants, or ITIN filers, you can get matched or learn more about support for ITIN and immigrant filers. BalancedRow is free to use for readers because participating accountants pay a flat fee for introductions.
If you work for yourself, some business costs may lower your taxes, but the rules depend on what the expense was, how you used it, and what proof you kept. Make a list, save your records, and hire a licensed CPA or IRS Enrolled Agent you verify yourself before sharing sensitive documents.
