sole proprietorship is what you are if you started doing business and did not file anything. There is no form, no fee, no state filing, no federal election. You report the numbers on Schedule C, you pay self-employment tax on Schedule SE, and the IRS and your state treat you as one economic person with two bank accounts.

That is the structure's appeal and its problem. Nothing stops you from using it, and nothing protects you while you do.

What a sole prop actually is

The Internal Revenue Code does not define "sole proprietorship" as its own entity. It defines the tax treatment. A single individual carrying on a trade or business files Schedule C to compute profit or loss and then carries the net figure to Schedule SE to compute self-employment tax. A single-member LLC that has not elected corporate treatment files the same Schedule C, because a single-member LLC is a disregarded entity for federal income tax purposes. The tax form does not care whether you have state liability protection. The state courts, as we will get to, do.

No state charter authorizes sole proprietorships because none needs to. A DBA (doing-business-as) name is a notice filing, not an entity. A creditor suing "Acme Consulting" when the proprietor is Jane Smith names Jane Smith.

The federal Corporate Transparency Act reporting rule, proposed by FinCEN on December 8, 2021 at 86 Fed. Reg. 69920, covers only entities "created by the filing of a document with a secretary of state or a similar office." Sole props are not created by a filing and are not reporting companies under 31 U.S.C. § 5336(a)(11)(A). A genuine administrative benefit, and also a symptom of the larger structural choice: a sole proprietorship is a thing the legal system does not recognize as a thing.

The self-employment tax math in 2022

Self-employment tax is the combined employer and employee share of FICA applied to self-employment earnings. Under IRC § 1401, the rate is 12.4% for old-age, survivors, and disability insurance plus 2.9% for hospital insurance (Medicare), totaling 15.3%. The OASDI component is capped at the Social Security wage base, which for calendar year 2022 SSA has set at $147,000, up from $142,800 in 2021. The Medicare component has no cap.

On top of that, the Additional Medicare Tax under IRC §§ 1401(b)(2) and 3101(b)(2) adds 0.9% on self-employment income above $200,000 for single filers, $250,000 for married filing jointly, and $125,000 for married filing separately. Those thresholds do not index for inflation; they have been the same dollar figures since 2013.

The base is 92.35% of net earnings, because IRC § 1402(a)(12) lets you back out the employer-equivalent share before multiplying. That small mercy does not change the core fact: a sole proprietor netting $100,000 owes roughly $14,130 in self-employment tax before seeing a cent of income tax, and that is the first dollar of a dedicated liability, not a total-tax-burden number.

The qualified-business-income deduction helps, up to a point. Section 199A still applies to sole props in 2022, and under Rev. Proc. 2021-45 the threshold above which the specified-service and W-2-wage limitations begin phasing in is $170,050 for single filers and $340,100 for joint filers. Below those thresholds, a sole proprietor can generally take 20% of qualified business income as a deduction; a single-member LLC or an S-corp shareholder gets the same treatment at the same income level. At this band, 199A is not a reason to prefer any structure over another.

What the sole prop does not protect

There is no liability shield. A creditor of the business is a creditor of the individual. A personal injury claim arising from the business reaches the proprietor's home, retirement assets outside ERISA-protected accounts, bank balances, and future wages. Contract claims by a supplier, a landlord, or a lender can be collected against any non-exempt asset in the state's execution process. The sole owner is the sole obligor.

There is no asset segregation rule the courts can use to protect you, because there is no entity to segregate from. In an LLC, a plaintiff must pierce the corporate veil to reach the member's personal assets, a doctrine that requires showing commingling, inadequate capitalization, or fraud. The LLC's failure modes are defensible. The sole prop has no shield to begin with.

Insurance can fill some of the gap. A general liability policy, and for professional-service businesses an errors-and-omissions policy, will respond to many claim types. Insurance also has limits, exclusions, and reservations-of-rights letters. If your business touches third parties with any regularity, an LLC plus insurance is a more honest pairing than insurance alone.

The switch points

Two separate questions drive the upgrade decision, and people confuse them.

The first is liability. The cost of an LLC in most states runs between a low-hundreds filing fee and an annual report or franchise tax that ranges from nothing (Arizona, Missouri) to $800 (California, under R&TC § 17941) to a few hundred dollars a year in the middle band. Compared to the expected value of one uninsured claim, those costs are rounding error. For any business that generates contracts, invoices, or foot traffic, forming an LLC is a defensible expense at any revenue level above hobby scale. The switch-point on liability is not a dollar figure; it is whether the business touches third parties.

The second is tax. An S-corp election changes the payroll-tax math, because an S-corp owner who also works in the business pays FICA only on reasonable W-2 compensation and takes the rest as a distribution not subject to SE tax. The IRS requires the W-2 portion to be "reasonable compensation," a standard enforced by examination and by the caselaw that has pushed hard on aggressive splits. Our payroll-tax crossover piece from 2021 carried the arithmetic in detail; the short version holds in 2022. The election starts paying for its added compliance cost (separate payroll, a 1120S return, more bookkeeping discipline) somewhere in the $60,000 to $80,000 band of net earnings after a reasonable-compensation haircut. Below that, the tax saved is smaller than the accounting bill the S-corp creates.

A proprietor netting $40,000 is not leaving meaningful tax dollars on the table. A proprietor netting $150,000 who has not considered either an LLC or an S-corp election is overpaying in tax and in unprotected liability, and the liability side usually hurts first.

The 1099-K change and why it matters to you this year

For calendar year 2022, the ARPA § 9674 change to IRC § 6050W drops the third-party-settlement-organization reporting threshold from $20,000 and 200 transactions to $600, with no transaction floor. That is a single-number change to one line of the Internal Revenue Code, and it reshapes the paper trail for every sole proprietor who accepts payments through Stripe, Square, PayPal Goods & Services, Venmo Business, Etsy, eBay, Uber, DoorDash, or any similar network.

Assume any revenue touching a third-party platform will appear on a Form 1099-K issued to you and to the IRS. The 1099-K reports gross, not net; it does not know your cost of goods, your platform fees, your refunds, or your chargebacks. Reconciling 1099-K gross against Schedule C net is the new homework ARPA hands you.

The honest recommendation

If you are a sole proprietor with annual net earnings under $40,000 and a business that does not touch third parties (no customers with real contracts, no landlord, no employees, no equipment that could injure someone), staying a sole prop is defensible. Track your expenses properly. File Schedule C. Pay quarterly estimateds on Form 1040-ES.

If your business touches third parties at any revenue, form an LLC. The liability shield is worth more than its cost. Our DBA vs LLC comparison from 2021 walks through why the DBA is not a substitute.

If your sole-prop net earnings are above roughly $60,000 and you are not yet formed, form an LLC now and run the S-corp election question against your actual numbers. The 2021 switch-point analysis still reads well in 2022; the wage base moved from $142,800 to $147,000, the 199A thresholds nudged with inflation, and the core arithmetic did not change.

The sole prop remains the right answer for a small number of genuinely small businesses. For everyone else, it is the answer that costs the least this week and the most over five years.
