What Happens If My Business Expenses Are More Than My Self-Employment Income?

You started a business, earned some money, and kept track of your expenses. Then you looked at the numbers and discovered something unsettling:

Your business expenses were higher than your business income.

Now what?

First, don’t panic. This does not automatically mean you did something wrong. New businesses commonly spend more than they earn while getting established. Even an existing business can have a loss during a slower year or after making a large investment.

However, a business loss can affect your tax return in several different ways. Let’s walk through what it may mean—and why accurate bookkeeping matters.

What should you do if your expenses exceed your income?
What should you do if your expenses exceed your income?

What Should You Do If Your Expenses Exceed Your Income?

If you are a sole proprietor or a single-member LLC taxed as a sole proprietorship, you will generally report your business income and expenses on Schedule C of your personal tax return.

Your business profit or loss is calculated using a fairly simple formula:

Business income − allowable business expenses = net profit or loss

For example:

  • Business income: $10,000
  • Allowable business expenses: $13,000
  • Business loss: $3,000

In this example, the business has a net loss of $3,000.

The loss is reported on Schedule C and then flows through to the owner’s personal tax return.

Can I Write Off Business Losses on My Personal Taxes?

Yes.

A legitimate business loss may reduce other income reported on your tax return. That could include:

  • Wages from a W-2 job
  • Your spouse’s wages if you file a joint return
  • Income from another business
  • Certain investment or retirement income
  • Other taxable income reported on the return

Let’s say you operate a small business while also working a regular job:

  • W-2 wages: $50,000
  • Schedule C business loss: $3,000

The $3,000 business loss may help reduce the amount of income subject to federal income tax.

However, this does not necessarily mean you will receive $3,000 back from the government. A deduction reduces taxable income; it is not usually a dollar-for-dollar tax credit or reimbursement.

Exactly how much the loss affects your taxes depends on your complete tax return, including your other income, deductions, credits, filing status, and any loss limitations that apply.

What If I Don’t Have Other Income?

If you have little or no other income, you may not be able to use the entire business loss during the current year.

In some cases, a business loss may contribute to a net operating loss, commonly called an NOL. An NOL may be carried forward and used to reduce taxable income in a future year.

However, your Schedule C loss and your net operating loss are not automatically the same number.

An NOL is calculated using information from your entire tax return, with certain deductions added back or adjusted. This is one reason it is helpful to work with a qualified tax professional when your business reports a loss—especially if the loss is significant.

The IRS provides additional information about these calculations in its guidance on net operating losses.

When Do You Have To Pay Self-Employment Tax?

Self-employment tax is generally calculated on your net earnings from self-employment, not your total business income before expenses.

If your allowable business expenses are higher than your business income, you generally do not have positive net earnings from that business on which to calculate self-employment tax.

In our earlier example:

  • Business income: $10,000
  • Allowable expenses: $13,000
  • Net business loss: $3,000

Because the business did not have a net profit, it would generally not generate self-employment tax for the year.

You may still owe federal income tax or other taxes because of income from another job, another business, investments, retirement distributions, or your spouse’s income.

A loss can also affect your future Social Security benefits because a year without net self-employment earnings may not add self-employment income to your Social Security earnings record.

Can All Business Expenses Be Tax Deductible?

Not necessarily.

For an expense to be deductible, it generally must be considered ordinary and necessary for your business. It should have a clear business purpose, and you need records showing what you purchased, how much you paid, and how it related to the business.

You also need to separate business expenses from personal expenses.

For example, you generally cannot deduct the entire cost of your phone, vehicle, internet service, or home utilities if you also use them personally. Only the allowable business portion may be deductible.

Some purchases are also handled differently for tax purposes. Equipment, furniture, vehicles, startup costs, inventory, and other large purchases may need to be depreciated, capitalized, or claimed under special rules rather than deducted as a regular expense all at once.

What Are Business Loss Limitations?

Certain deductions have limitations.

The home-office deduction is a common example. Under the regular home-office method, the deduction generally cannot exceed the income from the business after certain other expenses have been deducted. An unused amount may be carried forward, but it may not be allowed to create or increase the current business loss.

Other rules that may limit a loss include:

  • At-risk limitations
  • Passive-activity loss rules
  • Business-interest limitations
  • Partnership or S corporation basis limitations
  • Excess-business-loss limitations
  • Depreciation and vehicle deduction rules

Large business losses may require additional tax forms and calculations. The IRS explains that some noncorporate taxpayers must use Form 461 to determine whether the excess-business-loss limitation applies.

For a small Schedule C business with a modest loss, many of these rules may never come into play. Still, it is important to understand that “I spent the money” does not always mean “I can deduct all of it this year.”

Is It Okay for a Business to Lose Money?

Businesses do not have to make a profit every single year.

A loss may be understandable when:

  • You recently started the business
  • You purchased necessary equipment or supplies
  • You invested in education, marketing, or a new website
  • You experienced an unexpected interruption
  • Sales were temporarily lower than expected
  • You expanded the business
  • You changed products, services, or locations

What matters is that you are genuinely operating the business with the intention of making a profit.

The IRS considers several factors when deciding whether an activity is a business or a hobby. These include whether you operate in a businesslike manner, maintain accurate records, devote time and effort to the activity, have the knowledge needed to make it successful, and make changes intended to improve profitability.

One loss year does not automatically turn your business into a hobby. Even several loss years do not necessarily settle the question by themselves. How many years can you claim a business loss? The IRS looks at all the relevant facts and circumstances. You can read more in the IRS guidance on distinguishing a business from a hobby.

A Tax Loss and a Cash-Flow Problem Are Not the Same Thing

This is an important distinction.

A business can show a loss on its tax return without being in immediate financial trouble. Depreciation, startup spending, or a planned investment may contribute to the tax loss.

On the other hand, a business can show a profit and still struggle to pay its bills. Loan principal payments, owner draws, inventory purchases, and the timing of customer payments can affect cash flow differently than they affect taxable profit.

That is why it is helpful to review more than your Profit and Loss statement.

You may also need to look at:

  • Your Balance Sheet
  • Bank and credit-card balances
  • Accounts Receivable
  • Outstanding debt
  • Owner contributions and draws
  • Monthly cash flow
  • Which expenses are temporary and which will continue

Your tax return tells you one part of the story. Your bookkeeping helps you understand the rest.

Washington Business and Occupation Tax

Washington does not have a personal state income tax, but businesses may still be responsible for Business and Occupation tax, commonly called B&O tax.

B&O tax is generally based on gross business income, not net profit. Washington businesses usually cannot deduct regular operating expenses such as labor, materials, rent, or supplies when calculating B&O tax.

That means your business could report a loss for federal income-tax purposes and still have a Washington excise-tax filing requirement—or potentially owe B&O tax.

For example:

  • Gross business income: $20,000
  • Business expenses: $25,000
  • Federal Schedule C loss: $5,000

The business may have a federal tax loss, but Washington generally looks at the $20,000 of gross income when determining B&O tax before applying any available credits or other adjustments.

You can learn more through the Washington Department of Revenue.

What Happens If My Business Shows a Loss?

Start by making sure your bookkeeping is complete and accurate.

Review your records for:

  • Missing income
  • Duplicate expenses
  • Personal purchases recorded as business expenses
  • Large purchases that may require special treatment
  • Loan payments incorrectly recorded as expenses
  • Owner contributions or draws recorded as income or expenses
  • Vehicle, phone, internet, and home expenses that need to be divided between business and personal use
  • Expenses placed in the wrong categories

Once the books are accurate, look at what caused the loss.

Was it a planned investment? A slow sales year? A one-time equipment purchase? Are you still building your customer base? Or are your regular expenses consistently higher than your income?

That answer matters—not only for your tax return, but also for the future of your business.

The Bottom Line

If your allowable business expenses are higher than your self-employment income, your business may report a net loss.

That loss may reduce other taxable income on your federal return. If it cannot all be used in the current year, some or all of it may carry forward, depending on your complete tax situation and the limitations that apply.

A loss does not automatically mean you made a mistake. It also does not mean every dollar will produce a tax benefit—or that Washington taxes disappear just because the business was not profitable.

Accurate bookkeeping gives you and your tax professional the information needed to determine:

  • What caused the loss
  • Whether the expenses were recorded correctly
  • Which expenses may be deductible
  • Whether any deductions or losses carry forward
  • What the loss means for your business going forward

Most importantly, your records can help you see whether this was simply an investment year—or whether something needs to change.
