How to File Taxes As a Sole Proprietor
Although the IRS treats you and your business as one entity, filing taxes as a sole proprietor is not a once-per-year event. When you have an employer, your employer withholds taxes from each paycheck and remits those taxes to the government along with the portion that employer contributes for you. Without an employer, you are responsible for ensuring you pay the taxes–usually through quarterly estimated tax payments–that an employer would withhold and remit.
LLCs Taxed Like Sole Proprietorships
If your business is an LLC that the Internal Revenue Service (IRS) disregards for tax purposes, you file as if you were a sole proprietor. The IRS disregards single-member LLCs unless you affirmatively ask the IRS to tax your business as a corporation. When the IRS disregards an LLC, the company income and expenses are reported on the member's personal tax return.
Estimating Your Taxes
You must pay self-employment taxes if you make $400 or more in self-employment profits. The IRS taxes self-employment at a rate of 15.3%, split between 12.4% for Social Security and 2.9% for Medicare. In 2024, amounts you earn above $168,600 are not subject to the social security tax.
You owe an additional 0.9% Medicare tax if your overall income exceeds certain thresholds:
$250,000 if you are married and filing jointly
$200,000 if you are single, head of household with a qualifying person, or qualifying widow or widower with a dependent child
$125,000 if you are married but filing your taxes separately
Along with your self-employment taxes, you should pay your expected income tax at the standard rates.
To calculate your estimated taxes, the IRS recommends using Form 1040-ES. Estimate your expected profits for the year, determine how much your tax bill will be, and divide that amount into four quarterly payments.
Paying Quarterly Taxes
How does a sole proprietor pay taxes? The IRS recommends paying your estimated taxes online, but you may file Form 1040-ES by mail or pay your taxes by phone. So, when are sole proprietor taxes due? You pay estimated taxes four times per year:
April 15 for taxes covering January 1 to March 31
June 15 for taxes covering April 1 to May 31
September 15 for taxes covering June 1 to August 31
January 15 for taxes covering September 1 to December 31 of the previous year
Although estimated taxes are called "quarterly," a keen observer will note that payments can be unevenly distributed throughout the year based on when income is actually received. Keep the actual distribution of payments in mind when making your calculations. This can make estimated tax payments easier to handle for a sole proprietor that may have irregular income, especially for a new business. Of course, making four equal estimated tax payments will also work as long as a sufficient amount is paid in total.
You may owe a penalty if you fail to pay, underpay your estimated taxes by $1,000 or more, or pay less than 90% of your current-year or 100% of your prior-year taxes.
Tax Credits
Many consider the lack of benefits to be one of the most significant drawbacks of self-employment. However, you may qualify for credits or deductions to ease that burden. For example, amounts paid by a sole proprietor for health insurance may be deductible as an adjustment to income. In addition, a credit for small employer health insurance premiums might be applicable to the cost of certain coverage for some employees.
Self-employed individuals may be eligible for the Earned Income Tax Credit (EITC) if they have one or more qualifying children and:
Have earned $63,398 (2023 maximum) or less in income
Have accrued $11,000 or less in investment income
Have a valid social security number
Are a U.S. citizen or lawful permanent resident
Do not earn income outside the U.S.
You may still claim the EITC without a qualifying child if you meet all the regular qualifications and:
You may also qualify for other credits, such as the clean vehicle credit or the credit for small employer pension plan startup costs..
Tax Deductions
When you are self-employed, you can often take several deductions, especially business expense deductions. If you work in a home office, some of your supplies, equipment, and operating costs may be deductible. Examples of this include office supplies, computer equipment, internet service, and a home office deduction if a portion of the home is used regularly and exclusively for the sole proprietorship. Significantly, you may still deduct business expenses if you take the standard deduction.
You may also fund a retirement account, including:
Traditional or Roth Individual Retirement Account (IRA)
Simplified Employee Pension (SEP)
Solo 401(k)
Savings Incentive Match Plan for Employees (SIMPLE IRA Plan)
Other defined benefit plans
Other defined contribution plans
Depending on the plan, you may be able to deduct a portion of your contributions from your net income.
