How to Elect S-Corp Status: A Step-by-Step Guide for LLC Owners

What Is S-Corp Election?

An S-Corp election is a tax classification choice, not a separate business entity. Your LLC remains an LLC for legal purposes — you don't dissolve it or form a new company. You're simply telling the IRS: "I want my LLC to be taxed as an S-Corporation instead of as a disregarded entity or partnership."

The tax difference is significant. As an S-Corp, you split your business income between W-2 salary (subject to payroll taxes) and distributions (not subject to payroll taxes). That split can save $5,000–$20,000+ annually for businesses netting over $40,000.

Before diving into the how, review our LLC vs. S-Corp comparison to confirm the election makes financial sense for your income level.

Step 1: Confirm You Meet the S-Corp Eligibility Requirements

Before filing, confirm you meet all requirements:

• You must be a domestic corporation or eligible LLC
• All shareholders must be U.S. citizens or permanent residents (no foreign shareholders)
• No more than 100 shareholders
• Only one class of stock (different voting rights are permitted, but economic rights must be identical)
• Shareholders must be individuals, certain trusts, or estates (not corporations or partnerships)

For a typical single-owner LLC, all requirements are met by default.

Step 2: File IRS Form 2553

The S-Corp election is made by filing IRS Form 2553, "Election by a Small Business Corporation." Here's how to complete it:

Part I — Election Information

• Enter the company name, EIN, address, and date of incorporation
• Enter the first effective date of the S-Corp election (see deadline section below)
• Select your fiscal year (most businesses use calendar year — December 31)

Part I — Shareholder Consent

• Each shareholder must sign and date the form, consenting to the election
• For a single-member LLC, you're the only shareholder

Where to File

Mail or fax Form 2553 to the IRS service center for your state. Current addresses and fax numbers are listed in the Form 2553 instructions, which are updated annually. You can also file electronically through certain tax software platforms.

Step 3: Meet the Filing Deadlines

Timing is critical. The S-Corp election takes effect for a given tax year only if you file by specific deadlines:

• New business: File within 2 months and 15 days of the date you want the election to be effective (typically the date the business was incorporated or began operations)
• Existing business — effective for current year: File by March 15 of the current tax year (for calendar-year businesses)
• Existing business — effective for next year: File any time after March 15 to have the election take effect January 1 of the following year

If you miss the deadline, you can request relief under IRS Revenue Procedure 2013-30, which allows late elections in many circumstances. Work with a tax professional to file the late election request correctly.

Step 4: Set Up Payroll

Once the S-Corp election is effective, you must run payroll for yourself as a W-2 employee. This is not optional — the IRS requires that S-Corp owners who perform services for the corporation receive reasonable compensation through W-2 wages.

Steps for payroll setup:

1. Register for an EIN if you don't already have one (free at IRS.gov)
2. Register with your state's payroll tax agency
3. Set up payroll software (Gusto, QuickBooks Payroll, ADP Run)
4. Determine your reasonable salary (document the basis for the amount)
5. Run payroll at least quarterly; monthly is more common
6. Deposit payroll taxes semi-weekly or monthly depending on deposit schedule

Step 5: File Additional Tax Forms

As an S-Corp, your tax filing obligations increase:

• Form 1120-S: S-Corporation tax return (due March 15 — one month earlier than personal returns)
• Schedule K-1: Reports your share of the S-Corp's income, deductions, and credits to your personal return
• Form W-2: Your W-2 from the company, reflecting your salary
• Form 940 and 941: Employer tax filings for payroll

Plan for $800–$2,000 in additional annual accounting fees for the S-Corp return and K-1 preparation, on top of your existing tax preparation costs.

What Changes (and What Doesn't)

What changes after S-Corp election:

• You run payroll and receive W-2 wages
• Business profits pass through to you on Schedule K-1 (not Schedule C)
• Distributions above your salary are not subject to payroll taxes
• You file Form 1120-S in addition to your personal return

What stays the same:

• Your LLC remains your legal entity — same name, same EIN, same contracts
• Liability protection is unchanged
• Your business bank accounts and operations are unchanged

The Net Result

For a business netting $120,000 with a $55,000 salary, the S-Corp election typically saves $9,000–$11,000 per year after the added costs of payroll and accounting. Over five years, that's $45,000–$55,000 in your pocket rather than the IRS.
