Introduction

As a sole proprietor, you pay yourself through an owner's draw — not a salary — and you're responsible for filing and paying your own taxes, including self-employment tax and quarterly estimated payments. The IRS treats you and your business as one entity, so all business income flows through your personal return.

How sole proprietors pay themselves

Sole proprietors pay themselves through an owner's draw — a transfer of business profits to personal use. You can't pay yourself a W-2 salary from your own sole proprietorship. An owner's draw is simply moving money from your business account to yourself, by check, transfer, or cash, whenever the business has funds available.

No taxes are withheld when you take a draw. The business doesn't run payroll, issue you a W-2, or withhold income tax, Social Security, or Medicare. You handle all of that yourself when you file your annual return and make quarterly estimated payments.

Most sole proprietors open a dedicated business bank account, deposit all business income there, pay business expenses from it, and then transfer what they need to their personal account. That separation keeps your records clean and makes tax time much less painful. Mixing business and personal funds in one account isn't illegal for a sole proprietor, but it creates real headaches if the IRS ever takes a closer look.

  • Set up a business bank account before you start accepting or spending business money

  • Deposit all business income into the business account

  • Pay business expenses from the business account

  • Transfer money to your personal account when you need to pay yourself — that transfer is your owner's draw

  • Decide how often to take draws based on your cash flow, not a fixed payroll schedule

How filing taxes works as a sole proprietor

Sole proprietors report all business income and expenses on Schedule C (Form 1040), Profit or Loss From Business, which attaches to their personal Form 1040. The net profit from Schedule C flows directly into total taxable income. If that net profit is $400 or more, you also file Schedule SE to calculate self-employment tax.

Self-employment tax covers Social Security and Medicare — the taxes an employer would normally split with you. The rate is 15.3%, applied to 92.35% of your net self-employment earnings. You can deduct half of the self-employment tax you pay as an adjustment to income on your Form 1040, which reduces your taxable income.

Single-member LLCs that haven't elected corporate tax treatment are taxed the same way — the IRS disregards the LLC as a separate entity, and the owner files exactly like a sole proprietor using Schedule C and Schedule SE.

  • Schedule C (Form 1040): reports business income and expenses, calculates net profit or loss

  • Schedule SE (Form 1040): calculates self-employment tax on net earnings of $400 or more

  • Form 1040: the personal return that consolidates Schedule C and Schedule SE results

  • Form 1040-ES: used to calculate and pay quarterly estimated taxes

How quarterly estimated taxes work

Sole proprietors generally need to make estimated tax payments 4 times a year if they expect to owe at least $1,000 in tax when they file. Without an employer withholding taxes from each paycheck, you're responsible for sending those payments to the IRS yourself — covering both income tax and self-employment tax.

The IRS safe harbor rule says you generally avoid an underpayment penalty if you pay at least 90% of your current-year tax or 100% of your prior-year tax liability — whichever is smaller. If your adjusted gross income exceeded $150,000 in the prior year, that threshold rises to 110% of your prior-year liability. Use Form 1040-ES to estimate what you owe each quarter.

The quarterly due dates catch a lot of people off guard because they don't follow a clean three-month split. Missing a payment or underpaying by $1,000 or more can trigger a penalty, so it's worth setting calendar reminders well in advance.

  • April 15: covers January 1 through March 31

  • June 15: covers April 1 through May 31

  • September 15: covers June 1 through August 31

  • January 15 (following year): covers September 1 through December 31

Tax deductions and credits for sole proprietors

Sole proprietors can deduct ordinary and necessary business expenses on Schedule C, which directly reduces the net profit that self-employment tax and income tax are calculated on. The more legitimate deductions you capture, the lower your tax bill — and many sole proprietors leave money on the table by not tracking everything they're entitled to.

Common deductions include home office expenses (if a portion of your home is used regularly and exclusively for the business), office supplies, computer equipment, internet service, and health insurance premiums. You can also contribute to a retirement account — things like a SEP-IRA, Solo 401(k), or SIMPLE IRA — and deduct a portion of those contributions from your net income.

On the credits side, self-employed individuals may qualify for the Earned Income Tax Credit (EITC) if they meet income and other requirements. A tax professional can help you figure out which credits apply to your situation — the rules vary based on income, filing status, and whether you have qualifying dependents.

Employment taxes if you have workers

If your sole proprietorship has employees, you're responsible for withholding federal income tax, Social Security, and Medicare from their wages and remitting those amounts — plus your share as the employer — to the IRS. You'll also need to issue each employee a Form W-2 at year end and file Form W-3 to transmit those W-2s to the Social Security Administration.

If you hire contractors instead of employees, you don't withhold taxes from their payments. But if you pay a contractor $600 or more in a calendar year, you need to file Form 1099-NEC to report those payments to the IRS. Have every contractor fill out a Form W-9 before you pay them — it confirms their tax classification and gives you the information you need to file the 1099-NEC accurately.
