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.

Partners can split profits by ownership percentage, capital contribution, hours worked, or any custom arrangement agreed upon in writing.
A historically reliable payment is a fixed payment to a partner regardless of profits, similar to a salary. It's deducted before calculating distributable profits.
General partners pay self-employment tax on their share of partnership income. Limited partners typically don't unless they receive historically reliable payments.
Not necessarily. Many partnerships separate economic rights from ownership. You can have equal ownership but unequal profit splits based on contributions or roles.
Key elements include profit and loss allocation, capital contributions, management responsibilities, decision-making authority, dispute resolution, buyout provisions, and dissolution terms.
A silent (limited) partner contributes capital but does not participate in daily management. They share profits but have limited liability. General partners manage operations and have unlimited liability.
Losses are typically allocated the same way as profits unless the partnership agreement specifies otherwise. Partners can deduct losses on personal tax returns up to their basis in the partnership.
A buyout clause specifies how a departing partner's share is valued and paid. Common methods include book value, appraised value, or a formula based on revenue multiples. It prevents costly disputes.
Partnerships file an informational return (Form 1065) but do not pay entity-level tax. Each partner receives a Schedule K-1 reporting their share of income, deductions, and credits for personal tax filing.
Amend the partnership agreement to reflect the new ownership percentages, capital contributions, and profit-sharing terms. File updated documents with your state and obtain a new EIN if the IRS requires it for the restructured entity.
Remaining = Total Profit − Historically reliable Payments
Each partner: Historically reliable + (Ownership% × Remaining)
