A Texas-based freelance graphic designer earns $140,000 net profit/year from client work. She's evaluating whether to stay as a sole proprietor, form an LLC, or elect S-Corp status to reduce self-employment taxes.
Takeaway: S-Corp saves $8,300/year but adds ~$1,500-$3,000 in accounting fees (payroll, extra returns). Break-even is around $80-90K net profit. Below that, the overhead eats the savings. Texas has no state income tax, so the benefit is purely federal SE savings.
LLC annual fees range from $0 (Ohio) to $800 minimum (California, even for zero-revenue LLCs). Delaware C-Corp is standard for VC-backed companies but adds registered agent costs (~$300/yr) for out-of-state entities. The "best" structure is state-specific.
S-Corps cannot have more than 100 shareholders, cannot have non-US shareholders, and cannot have corporate shareholders. Violating these rules (e.g., adding a foreign investor) terminates S-Corp status retroactively, potentially creating a large unexpected tax event.
The IRS requires S-Corp owner-employees to pay themselves a "reasonable salary" before taking distributions. There is no fixed formula — the IRS looks at industry benchmarks, duties, and hours worked. Setting the salary too low is a common audit trigger for S-Corps.
Business break-even models track revenue vs. direct costs. They rarely factor in the owner's time as a cost. If you're working 60 hours/week at imputed $50/hour, your "profitable" business may be paying you $12/hour after the opportunity cost calculation.
Break-Even CalculatorA service business valued on EBITDA multiples (2-4×) gets a very different number than one valued on SDE (seller's discretionary earnings) or discounted cash flow. Buyers and sellers typically use different methods to argue their preferred price. This calculator uses a single method.

A utility patent costs $10,000–$30,000+ in total, including USPTO fees ($320–$1,760 filing) and attorney fees ($5,000–$20,000+). Design patents are cheaper: $2,000–$5,000 total.
A provisional patent (PPA) costs $160–$320 in USPTO fees plus attorney fees ($1,500–$3,000). It establishes a priority date and gives you 12 months to file a full utility patent. It never becomes a patent on its own.
Utility patents last 20 years from the filing date. Design patents last 15 years. Maintenance fees are due at 3.5, 7.5, and 11.5 years for utility patents.
Yes, but it's risky. Pro se (self-filed) patents often have weaker claims. For valuable inventions, an experienced patent attorney helps maximize protection.
A utility patent protects how an invention works (function and process). A design patent protects how it looks (ornamental appearance). Utility patents cost more but offer broader protection.
Utility patents take 2-4 years on average from filing to issuance. Design patents take 12-18 months. Provisional patents establish a filing date but must be followed by a full application within 12 months.
Utility patents require maintenance fees at 3.5 years ($2,000), 7.5 years ($3,760), and 11.5 years ($7,700) after issuance. Failure to pay forfeits the patent. Small entities pay reduced fees.
No. Patents require a specific, concrete invention. You may want to describe how to make and use the invention in sufficient detail. Abstract ideas, natural phenomena, and mathematical formulas are not patentable.
A patent search reviews existing patents and publications to determine if your invention is novel. It costs $500-$2,000 and can save thousands by identifying conflicts before filing a full application.
File a Patent Cooperation Treaty (PCT) application to seek protection in over 150 countries. The PCT filing costs $3,000-$5,000 in fees and provides 30 months to enter individual countries, where national fees and translations add $3,000-$7,000 per country.
