Self-Employment Taxes & Business Expenses: What You Can Deduct and How to Keep Records

Making money for yourself in America can be very different from working as a W-2 employee.

If you run a business, freelance, sell products, perform services or participate in gig work, you may be considered self-employed for federal tax purposes.

That means you need to understand four important concepts:

  1. Business income
  2. Business expenses
  3. Business profit
  4. Self-employment tax

You should also understand how to keep records, track inventory and choose an accounting method.

Let’s make it simple.


What Does Self-Employed Mean?

You may be self-employed if you operate a trade or business for yourself.

Examples can include:

  • Freelance graphic designer
  • Consultant
  • Tutor
  • Cleaning business
  • Landscaping business
  • Online seller
  • Reseller
  • Photographer
  • Delivery driver
  • Rideshare driver
  • Repair business
  • Food business
  • Website business
  • Independent contractor
  • Beauty service provider
  • Home-based business

You do not necessarily need an LLC or corporation to have self-employment income.

A person operating a business individually may be a sole proprietor for federal tax purposes.


Self-Employed Does Not Mean Tax-Free

Sometimes new business owners think:

“No taxes came out of the money, so I don’t owe tax.”

That is not how it works.

When you are an employee, your employer often withholds taxes from your paycheck.

When you are self-employed, nobody may be withholding those taxes for you.

You may have to handle them yourself.


Revenue Is Not the Same as Profit

This may be the single most important business concept to understand.

Suppose customers pay your business:

$100,000

That is revenue.

Now suppose qualifying business costs total:

$40,000

Your simplified business profit would be:

$100,000 revenue

minus

$40,000 allowable costs

=

$60,000 profit

You are not necessarily taxed as though the entire $100,000 were profit.


Schedule C

Many sole proprietors report their business activity using:

Schedule C — Profit or Loss From Business

Schedule C generally reports:

Income

minus

Cost of goods sold, when applicable

minus

Allowable business expenses

=

Net profit or loss

The resulting business income ultimately becomes part of your individual federal tax return.

If you have only worked as an employee before, start with:

How Form 1040 Works


Do I Need a 1099 to Report Business Income?

No.

This is extremely important.

Receiving a 1099 is not what makes income taxable.

Suppose you earned:

  • $500 in cash
  • $1,000 by check
  • $2,000 through a payment app
  • $5,000 from customers who never issued a 1099

The fact that you did not receive a tax form does not automatically make that income non-taxable.

Your own business records matter.


What Is a Deductible Business Expense?

The IRS generally describes deductible business expenses as expenses that are ordinary and necessary for carrying on your trade or business.

Ordinary

Common and accepted in your type of business.

Necessary

Helpful and appropriate for the business.

“Necessary” does not mean that the expense must be absolutely indispensable.

But this does not mean you can deduct anything you want because you own a business.


Common Business Expense Categories

Depending on your business and the facts, deductible expenses may include categories such as:

Advertising

Examples:

  • Online advertising
  • Google Ads
  • Social media advertising
  • Flyers
  • Business cards
  • Signs
  • Promotional materials

Office Expenses

Examples can include:

  • Paper
  • Pens
  • Printer supplies
  • Postage
  • Other ordinary office supplies

Website and Online Business Expenses

Depending on the circumstances, business-related costs may include:

  • Domain registration
  • Web hosting
  • Business email
  • Software
  • Website services
  • Online tools
  • Certain development costs

Some larger expenditures or long-lived assets may require different tax treatment rather than an immediate deduction.


Legal and Professional Services

Potential business expenses can include fees paid to professionals for business-related services, such as:

  • Accountant
  • Bookkeeper
  • Attorney
  • Tax professional

Personal legal or accounting expenses are different.


Business Insurance

Certain insurance premiums connected with operating your business may qualify as business expenses.

Personal insurance should not automatically be placed on Schedule C.


Rent or Lease Expenses

If you rent property or equipment for your business, qualifying business rent may be deductible.

Different rules can apply to:

  • Real estate
  • Equipment
  • Vehicles
  • Home-office arrangements

Supplies

Supplies used in operating your business may be deductible when the applicable tax rules are met.

Examples might include:

  • Cleaning products for a cleaning business
  • Packaging supplies for an online seller
  • Small consumable tools
  • Printing supplies

Contract Labor

If you hire independent contractors for legitimate business purposes, those payments may be business expenses.

However, hiring workers can also create tax-reporting obligations.

Do not assume that simply calling someone a “contractor” legally makes them an independent contractor.

Worker classification rules matter.

Employee Wages

If your business hires employees, wages and certain employee-related costs may be business expenses.

But having employees also creates payroll responsibilities such as:

  • Payroll tax withholding
  • Employer payroll taxes
  • W-2 reporting
  • Employment tax filings
  • State employment requirements

Business Use of a Vehicle

Vehicle deductions are a common source of confusion.

Business use of a vehicle can potentially qualify for a deduction under applicable rules.

But:

Your regular commute is generally not the same thing as business mileage.

For example, driving from your home to your normal workplace generally receives different tax treatment from driving between qualifying business locations.

Keep a mileage log showing:

  • Date
  • Starting point
  • Destination
  • Business purpose
  • Business miles

Can I Deduct My Clothes?

Usually, normal clothing that can be worn outside work is not automatically deductible just because you wear it while working.

Specialized clothing or uniforms can involve different rules.

Do not assume:

“I bought it for work” = automatically deductible.


Can I Deduct Food?

Buying yourself lunch while working does not automatically turn lunch into a business expense.

Business meal deductions have specific requirements and limitations.

Keep records showing:

  • Date
  • Amount
  • Business purpose
  • People involved when relevant

Personal Expenses Are NOT Business Expenses

Examples of personal expenses generally include:

  • Groceries
  • Family vacations
  • Personal clothing
  • Children’s expenses
  • Personal entertainment
  • Household expenses
  • Personal mortgage payments
  • Personal rent
  • Personal commuting

Owning a business does not transform personal spending into business deductions.


Mixed Business and Personal Expenses

Some expenses are partly business and partly personal.

For example:

Your phone bill is:

$100 per month

Suppose legitimate business use is:

40%

You generally should not simply deduct the entire $100 as though there were no personal use.

The proper treatment depends on the applicable tax rules and your documented business usage.


What Is Business Overhead?

Overhead is an accounting and management term describing costs necessary to operate a business that are not easily tied directly to one individual product or service.

For example, imagine a cleaning company.

Direct job costs

  • Cleaning supplies used on a customer’s job
  • Labor performing the cleaning

Possible overhead

  • Accounting software
  • Business insurance
  • Website hosting
  • Administrative payroll
  • Office costs
  • Telephone service
  • General advertising

Overhead Is Not One Big Tax Deduction Category

This distinction is important.

A business owner may call $20,000 of expenses:

“overhead”

for management purposes.

But Schedule C may divide those expenses into categories such as:

  • Advertising
  • Insurance
  • Legal and professional services
  • Office expense
  • Rent
  • Supplies
  • Utilities
  • Other expenses

Your bookkeeping categories should make it possible to properly classify expenses at tax time.


Direct Costs vs. Overhead

Suppose you sell custom T-shirts.

You might think about your costs this way:

Direct product costs

  • Blank shirts
  • Printing material
  • Packaging directly connected with merchandise

Overhead

  • Accounting software
  • Website
  • Business insurance
  • Administrative expenses
  • General advertising

Knowing the difference helps you calculate whether the business is actually profitable.


Inventory: This Is Different From Normal Expenses

If your business buys or produces products for resale, you may need to understand inventory.

Suppose you buy:

100 handbags

at

$20 each

Total:

$2,000

Those handbags are products being held for resale.

Inventory and cost-of-goods-sold accounting can work differently from simply deducting an ordinary office expense.


What Is Cost of Goods Sold — COGS?

Cost of Goods Sold generally represents the cost associated with products sold by your business.

A simplified example:

Beginning inventory

$5,000

Plus purchases

$20,000

Goods available

$25,000

Minus ending inventory

$7,000

Cost of Goods Sold

$18,000

Now suppose sales were:

$40,000

Subtract COGS:

$40,000 – $18,000 = $22,000

That $22,000 is gross profit before subtracting other applicable business expenses.


Inventory Example: Why It Matters

Imagine you buy $10,000 worth of merchandise in December.

You only sell $2,000 worth before December 31.

You cannot always assume:

“I spent $10,000, so I deduct $10,000 exactly like office supplies.”

Inventory rules can affect when product costs are recognized.

Small-business taxpayers may qualify for simplified inventory-accounting rules, but you still need a consistent system that properly reflects income.

Businesses carrying significant inventory should consider professional tax or accounting assistance.


Cash Accounting vs. Accrual Accounting

Your accounting method determines when you recognize income and expenses.

Two major methods are:

Cash method

and

Accrual method


Cash Method

Under the cash method, income is generally recognized when you receive it and expenses when you pay them, subject to applicable tax rules.

Example

You complete work:

December 20

You invoice customer:

December 20

Customer pays:

January 5

Under the cash method, the income would generally be recognized when received in January.


Accrual Method

Under accrual accounting, income is generally recognized when earned under applicable rules rather than simply when cash arrives.

Example

Service completed:

December 20

Invoice issued:

December 20

Payment received:

January 5

An accrual-method business may generally recognize the income in December.

Expenses are likewise generally recognized according to accrual rules rather than simply based on the date money leaves your account.


Which Accounting Method Should a Small Business Use?

Many small sole proprietors use the cash method because it is relatively simple.

But not every business can automatically use whichever method it wants.

Factors such as:

  • Type of business
  • Inventory
  • Business size
  • Prior accounting method
  • Tax rules

can affect the answer.

Once you establish an accounting method, changing methods can sometimes require special tax procedures or IRS approval.

Consistency matters.


How Should I Record Business Expenses?

You do not need to own expensive accounting software just to maintain records.

Your records should clearly show:

  • Income
  • Expenses
  • Purchases
  • Sales
  • Assets
  • Inventory, if applicable
  • Amount
  • Date
  • Business purpose

Simple Business Expense Tracker

A spreadsheet might contain:

DateVendorDescriptionCategoryBusiness PurposeAmount
Jan. 5Hosting companyWebsite hostingWebsiteBusiness website$150
Jan. 8GoogleOnline adsAdvertisingCustomer acquisition$200
Jan. 12Office storePrinter paperOffice expenseBusiness documents$35
Jan. 15SupplierMerchandiseInventoryProducts for resale$500

The important part is not using a fancy system.

The important part is maintaining complete, accurate and organized records.


Keep Receipts and Supporting Records

Do not simply create a spreadsheet at tax time saying:

Advertising — $8,000

and have no idea where the number came from.

Keep supporting records.

Examples include:

  • Receipts
  • Invoices
  • Bank statements
  • Credit-card statements
  • Sales records
  • Deposit records
  • Canceled checks
  • Mileage logs
  • Contracts

Do Bank Statements Alone Prove a Business Deduction?

A bank or credit-card statement can help establish that you paid something.

But you should also be able to establish the business purpose of the expense.

For example:

A credit-card statement saying:

Amazon — $248

does not by itself explain whether you purchased:

  • Business shipping supplies

or

  • A television for your bedroom.

Documentation matters.


Separate Business and Personal Accounts

Keeping business and personal transactions separate can make bookkeeping much easier.

A simple system could look like:

Business checking account

Receive customer payments.

Business credit card

Pay qualifying business costs.

Personal account

Pay household and personal expenses.

This makes it much easier to identify business transactions when preparing taxes.


Record Expenses Throughout the Year

Do not wait until April and attempt to remember everything you purchased during the previous year.

A simple monthly routine can work well.

During the month

Record income and expenses.

End of month

Compare your records with your bank and credit-card statements.

End of year

Total the categories needed for tax preparation.


What Is a Profit and Loss Statement?

A basic Profit and Loss Statement — P&L summarizes your business performance.

For example:

Revenue

$100,000

Cost of Goods Sold

-$30,000

Gross Profit

$70,000

Operating Expenses

-$25,000

Net Business Profit

$45,000

This is much more useful than simply looking at how much cash is currently sitting in your bank account.


Profit Is Not the Same as Cash in the Bank

Your business bank balance could be:

$20,000

while your taxable business profit is:

$45,000

Or your bank account could contain $50,000 while the business has much less actual profit.

Cash balance and accounting profit are not the same measurement.


Self-Employment Tax

Self-employed individuals may have to pay self-employment tax in addition to regular income tax.

Self-employment tax generally funds:

  • Social Security
  • Medicare

Employees normally share Social Security and Medicare payroll taxes with their employers.

Self-employed people effectively account for both portions through the self-employment tax system.

For 2025 returns, Schedule SE generally becomes relevant when net earnings from self-employment reach $400 or more, subject to the specific rules and exceptions.


Schedule SE

Schedule SE is used to calculate self-employment tax.

Your Schedule C business profit generally feeds into the self-employment tax calculation when applicable.

This is why:

Business revenue

is not the final tax number.

Expenses affect:

Business profit

which can affect:

  • Federal income tax
  • Self-employment tax
  • Certain deductions and credits

Estimated Quarterly Taxes

Because a self-employed person may not have an employer withholding taxes from each payment, the federal tax system may require estimated tax payments during the year.

You may hear these called:

Quarterly estimated taxes.

This does not necessarily mean every self-employed person must blindly send the same amount four times per year.

Estimated tax requirements depend on your expected income, tax liability, withholding and other circumstances.


What If I Have a W-2 Job AND a Business?

That is completely possible.

For example:

Day job

W-2 employee

and

Weekend business

Self-employed photographer

Your federal return might include both:

W-2 wages

and

Schedule C business income

The two types of income ultimately become part of the same individual income tax return.

Can Tax Software Handle Self-Employment?

Many tax-software programs support self-employment returns.

Examples include:

  • TurboTax
  • TaxAct
  • FreeTaxUSA
  • H&R Block
  • TaxSlayer

However, self-employment features may not always be included in the cheapest or free commercial tier.

Check pricing before choosing a product.

The IRS Free File program may also provide appropriate filing options to eligible taxpayers, depending on the provider and tax situation.


When Should You Consider Professional Help?

Self-employment returns become more complicated when you have:

  • Significant inventory
  • Employees
  • Large equipment purchases
  • Depreciation
  • Home-office deductions
  • Multiple businesses
  • Partnerships
  • Corporations
  • Large vehicle deductions
  • International transactions
  • Complicated accounting methods

In those situations, a qualified CPA, enrolled agent or other appropriate tax professional may be worthwhile.


Simple Self-Employment Checklist

Before tax time, know:

  • How much total revenue you received
  • How much inventory you purchased
  • Your beginning and ending inventory when applicable
  • Your cost of goods sold
  • Your ordinary business expenses
  • Your business mileage
