A sole proprietorship is the most basic and informal way to conduct a business.

You don’t need permission to start doing business as a sole proprietorship. You don’t need to maintain any records other than what is minimally necessary to show your income and expenses on your tax return.

If you wish to use an artificial business name, you’ll need to file a DBA ("doing-business-as") certificate with your county.

As a sole proprietor, you have the ultimate freedom to operate your business in the manner you see fit. And if you decide to close or wind down your business for any reason, a sole proprietorship is the least cumbersome entity to end.

Starting a sole proprietorship

No taxable event

If you’re starting out as a sole proprietorship, you will likely start by dedicating personal assets or purchasing assets required to get things off the ground. 

It’s helpful to know that you can transfer property to the sole proprietorship without tax consequences since the sole proprietorship is not a separate entity for federal tax purposes. 

Hiring and EIN

Despite not being a separate legal entity, your business may need to apply for its own Employer Identification Number (EIN) if you anticipate hiring employees. See below for withholding rules.

Setting up payroll

Once hired, you must collect information about the employees' withholding exemptions, withhold income taxes from the employees' salaries based on these withholding exemptions, and remit the income taxes withheld at the appropriate times. 

The proprietor must withhold the employees' portion of FICA taxes and pay the employer's portion of FICA, FUTA and state unemployment taxes and workers' compensation premiums. If the sole proprietor has common-law employees, he or she must file Form SS-4 with the IRS to get an EIN.

Decide on tax year and accounting method

You must also choose the tax year and the accounting method you will use, although sole proprietorships must use the tax year of its owner, which will usually be a calendar year.

Personal liability for your business

The biggest drawback of operating as a sole proprietorship is that it does not provide any asset protection, leaving you exposed to liabilities of the business and other litigious claims.

If you’re averse to this level of risk, consider purchasing liability insurance. 

Alternatively, you can convert your sole proprietorship to an LLC, PLLC, or certain corporations without any tax consequences.

Taxing a sole proprietorship

Whether you, as the sole proprietor, withdraw the profits or place them back into the business, any income you make as a therapist should be reported as taxable income on Schedule C of Form 1040, your individual income tax return.

Self-employment tax

Your business profits also constitute self-employment income, which is subject to self-employment tax (computed on Schedule SE of Form 1040).  

Since there is no employer to share the burden, you can expect to pay Social Security tax at the higher, self-employed rate.

Filing your tax return

As mentioned above, the income from your sole proprietorship ultimately flows to your Individual Income Tax Return (Form 1040).  

Even if your therapy practice is small, tax season can feel hectic. It’s never too early to start preparing. Check off the applicable items below and track everything you need for you or your accountant to file your taxes.
