DIRECT ANSWER
What to know first
A sole proprietor generally reports business activity on Schedule C with the individual return. An S corporation files a separate Form 1120-S, issues Schedule K-1, and may create payroll and owner-compensation requirements. An S election is not automatically better; the decision depends on profit, services performed, payroll cost, state rules, administration, and the owner's broader facts.
How the federal filing process changes
A sole proprietorship is not a separate federal income-tax entity from its owner. Business income and expenses are generally reported on Schedule C, and net earnings can be subject to self-employment tax under the applicable rules.
An eligible entity that makes a valid S election generally files Form 1120-S and passes tax items to shareholders on Schedule K-1. The owner then coordinates the entity return with the individual return.
Payroll and reasonable compensation
A shareholder who performs services for an S corporation may be an employee. IRS guidance states that an S corporation must pay reasonable compensation for services before treating payments as non-wage distributions when the facts require wages.
Reasonable compensation is based on the work and facts, not a universal percentage. Payroll filings, deposits, benefits, state registrations, and records add ongoing administration that should be considered before an election.
Questions to compare before electing
- Expected recurring profit and how the business earns it
- The owner's duties, time, and market compensation
- Payroll, bookkeeping, tax-return, and state compliance costs
- Eligibility, ownership, entity documents, and election timing
- State tax treatment and whether legal advice is also needed
