Electing S corporation treatment does not change your LLC's legal structure. It changes how it is taxed. That can reduce self-employment tax on part of your profit, but it also adds obligations, so the decision should rest on numbers rather than hype.
How an LLC is taxed by default
- Single-member LLC: disregarded, taxed on the owner's personal return.
- Multi-member LLC: taxed as a partnership.
- Either can elect corporate treatment, including S corporation status.
Who qualifies
- A domestic entity.
- No more than 100 shareholders.
- Only eligible shareholders, such as U.S. individuals, certain trusts and estates. Nonresident aliens and most entities cannot be shareholders.
- Only one class of stock, meaning distributions must be proportionate to ownership.
The election: Form 2553
An LLC elects S corporation status by filing Form 2553. In general it must be filed no more than 2 months and 15 days after the beginning of the tax year the election is to take effect, or during the preceding tax year. Late elections may qualify for relief if there was reasonable cause, but do not rely on that. Confirm the current instructions on IRS.gov before filing.
Why it can save tax
Sole proprietors and default partnerships pay self-employment tax on all net earnings. In an S corporation, the owner must be paid a reasonable salary subject to payroll tax, and remaining profit is distributed without payroll tax. See S-corp reasonable salary for the IRS rules and a worked illustration.
What it costs you
- Payroll setup, ongoing payroll filings, and employment tax deposits.
- A separate Form 1120-S return each year. See S corp tax preparation cost.
- State-level entity taxes or fees in some states.
- Stricter rules on distributions, loans, and owner basis.
- Reasonable salary that may be higher than you would otherwise take.
- Reduced flexibility in allocating profits between owners.
When it usually makes sense
- 1Profit is comfortably above what you would pay yourself as a salary.
- 2You actively work in the business, so salary is clearly required.
- 3You are willing to run payroll and keep clean books.
- 4Your state does not erase the benefit with entity-level taxes.
- 5The projected tax savings exceed the added compliance cost with room to spare.
When to hold off
- Profits are low or unstable.
- You expect to contribute appreciated property or want flexible allocations.
- You are not ready to maintain payroll and bookkeeping.
