Filing Form 2553 tells the IRS you want your corporation or LLC to be taxed as an S corporation under Subchapter S of the Internal Revenue Code. This changes how your business income is taxed — profits and losses pass through to your personal tax return, and you may be able to reduce self-employment taxes by splitting income between a salary and distributions.
The election does not change your legal structure — your LLC remains an LLC at the state level. It only changes your federal tax classification.
This is a decision that depends on your specific financial situation — this tool cannot make that determination for you. As a general rule, S-corp status tends to help when your business generates consistent net profit above roughly $80,000–$100,000, because the potential payroll tax savings can outweigh the added complexity and cost (payroll administration, separate business return, reasonable salary requirements).
Before electing, confirm the math with a CPA who has reviewed your actual numbers. The general information here is not advice about your situation.
To qualify as an S corporation, your entity must: (1) be a domestic corporation or LLC treated as a corporation, (2) have no more than 100 shareholders, (3) have only eligible shareholders — U.S. citizens or permanent residents, certain trusts, and estates (no partnerships, corporations, or non-resident aliens), and (4) have only one class of stock (LLCs must have equal economic rights).
If any of these conditions aren't met, the election will be invalid. If you have foreign founders or investors, or complex ownership structures, consult an attorney before filing.
S-corp shareholder-employees must pay themselves a reasonable salary before taking distributions. The IRS defines "reasonable" as compensation comparable to what you'd pay someone else to do the same work in an arm's-length transaction. If your salary is too low, the IRS can reclassify distributions as wages and assess back payroll taxes plus penalties.
Setting this correctly is one of the most important steps after your election takes effect. Consult a CPA to determine the right range for your role and income level.
Federal S-corp status does not automatically apply at the state level. Most states recognize the federal election, but some require a separate state-level election or impose additional taxes on S corporations. California, for example, charges an S-corp franchise tax and an additional 1.5% tax on net income. New York City does not recognize S-corp status at all for city tax purposes.
Check your state's specific requirements with a local CPA or tax attorney before assuming your state treatment mirrors federal.
The IRS will send you a written notice (CP261) confirming your S-corp election, typically within 60 days of receipt. Keep this notice permanently — it's proof your election was accepted. If you don't receive it within 60 days, contact the IRS to confirm receipt.
Once effective, you'll need to: file Form 1120-S (S-corp return) annually instead of 1065 or 1040 Schedule C, run payroll and pay yourself a reasonable salary, and issue K-1s to all shareholders each year.
