Introduction
If your LLC is generating solid profits, you may have heard that electing S-corp tax status could save you thousands of dollars a year in self-employment taxes. Good news: you don’t need to dissolve your LLC and start over. You can keep your LLC’s legal structure while simply changing how it’s taxed by the IRS.
This guide walks you through exactly how to convert your LLC to an S-corp for tax purposes, step by step.
What you’ll accomplish: By the end of this guide, you’ll have filed the correct paperwork with the IRS to have your LLC taxed as an S-corporation, potentially reducing your self-employment tax burden while keeping your LLC’s liability protection intact.
Who this guide is for: This guide is for LLC owners whose businesses are profitable enough (generally $40,000+ in net income) to benefit from S-corp taxation, and who want a straightforward, plain-English walkthrough of the process.
What you’ll need:
- Your LLC’s Employer Identification Number (EIN)
- Your LLC formation documents
- Basic financial information about your business
- IRS Form 2553 (and potentially Form 8832)
- A payroll system or provider (you’ll need this after conversion)
Before You Start
Prerequisites
Before diving into the paperwork, make sure your business actually qualifies for S-corp election. The IRS has specific eligibility rules:
- Your LLC must be a domestic (U.S.-based) business
- You can have no more than 100 members/shareholders
- All members must be U.S. citizens or resident aliens (no non-resident alien owners)
- You can only have one class of ownership interest (no preferred vs. common member classes)
- Other LLCs, corporations, or partnerships generally cannot be members (with limited exceptions)
Preparation Steps
1. Run the numbers first. S-corp status isn’t automatically beneficial. It makes the most sense when your business nets at least $40,000–$60,000 in annual profit, because you’ll need to pay yourself a “reasonable salary” through payroll, and payroll comes with added costs (payroll processing, employer payroll taxes, more complex bookkeeping).
2. Talk to a tax professional or accountant. This is the single most important preparation step. A CPA can model out your actual tax savings and help determine a reasonable salary figure for your role.
3. Check your state’s rules. Some states (like New York) require a separate state-level S-corp election in addition to the federal one.
Information to Gather
- Your LLC’s legal name (exactly as registered with the state)
- EIN (Employer Identification Number)
- Date your LLC was formed
- State of formation
- Names, addresses, and Social Security numbers of all LLC members
- Ownership percentage of each member
- Your LLC’s tax year (calendar year, for most small businesses)
Step-by-Step Process
Step 1: Confirm Your LLC’s Default Tax Status
Before converting, understand where you’re starting from. By default, a single-member LLC is taxed as a “disregarded entity,” and a multi-member LLC is taxed as a partnership. S-corp election changes this tax classification without changing your legal entity type.
Tip: You don’t need to file as a corporation first—the IRS allows LLCs to elect S-corp tax treatment directly.
Step 2: Decide Between Form 2553 Alone or Form 8832 + Form 2553
For most LLCs, filing IRS Form 2553 alone is sufficient—this form both requests S-corp treatment. However, in certain situations (like correcting a prior election or specific timing issues), your accountant might recommend also filing Form 8832 (Entity Classification Election) first to formally elect corporate tax status, followed by Form 2553.
Tip: When in doubt, Form 2553 alone works for the vast majority of LLCs making this switch.
Step 3: Complete IRS Form 2553
This is the core document for your conversion. You’ll need to fill out:
- Part I: Basic election information—your LLC’s name, address, EIN, effective date of election, and tax year
- Signatures: Every LLC member must sign, consenting to the S-corp election
- Part II: Only required if you’re selecting a fiscal year other than the calendar year
- Part III: Only applies to certain qualified subchapter S trusts (most small businesses skip this)
Tip: Double-check that your EIN and legal business name match IRS records exactly—mismatches are the #1 cause of rejected forms.
Step 4: Choose Your Effective Date Carefully
Form 2553 asks when you want the S-corp election to take effect. You have two main options:
- Retroactive to the current tax year: You must file within 2 months and 15 days of the start of the tax year you want the election to apply to (for calendar-year businesses, that’s March 15).
- Effective for the next tax year: File anytime during the current year, and it takes effect January 1 of the following year.
Tip: Missed the deadline? You may still qualify for late election relief (see Common Mistakes below).
Step 5: File Form 2553 with the IRS
Mail or fax the completed form to the IRS service center for your state (listed in the Form 2553 instructions). There’s no filing fee for this election.
Tip: Send it via certified mail with a return receipt, or use fax with a confirmation printout—you’ll want proof of timely filing.
Step 6: Wait for IRS Confirmation
The IRS typically takes 60–90 days to process Form 2553. You’ll receive a confirmation letter (CP261 Notice) approving your S-corp election. Keep this document permanently with your business records.
Tip: No response after 90 days? Call the IRS Business & Specialty Tax Line to check status before assuming something went wrong.
Step 7: Set Up Payroll for Owner-Employees
Once your S-corp election is approved, any owner actively working in the business must be paid a “reasonable salary” through formal payroll—complete with tax withholding, W-2s, and employer payroll tax filings.
Tip: Set this up before your effective date, not after—retroactive payroll corrections are messy and can trigger IRS scrutiny.
Step 8: Update Your Accounting and Bookkeeping
Your bookkeeping needs to shift to reflect distinct categories: owner salary (payroll expense), payroll tax expense, and shareholder distributions (profit above salary). This distinction is the whole point of S-corp tax savings.
Tip: Consider bookkeeping software or a bookkeeper experienced with S-corps, since the accounting is more nuanced than a standard LLC.
Requirements
Documents needed:
- IRS Form 2553 (required)
- IRS Form 8832 (only if applicable)
- LLC operating agreement (for reference on ownership percentages)
- EIN confirmation letter
Information required:
- Legal business name and address matching IRS records
- EIN
- Names, addresses, SSNs, and ownership percentages of all members
- Selected tax year and effective date
- Signatures of all LLC members
State considerations:
- Most states automatically recognize your federal S-corp election for state tax purposes
- Some states (New York, New Jersey, Arkansas, among others) require a separate state-level S-corp election form
- A few states (like California and Texas) impose additional franchise taxes or fees on S-corps—check with your state’s tax agency
- Your LLC’s legal status with the state does NOT change—you remain an LLC legally; only your tax treatment changes
Tips for Success
1. File early, not at the deadline. Give yourself buffer time in case the IRS requests corrections or additional information.
2. Get a reasonable salary analysis done professionally. The IRS scrutinizes S-corp owner salaries that seem artificially low compared to distributions—this is the most common audit trigger.
3. Keep all IRS correspondence. Store your CP261 approval notice somewhere safe and accessible; you may need it when opening business bank accounts or applying for loans.
4. Coordinate the switch with your accountant’s calendar. Converting mid-year adds complexity to your books, so many business owners prefer a January 1 effective date.
5. Separate business and payroll bank accounts. Once you have salary and distributions flowing differently, cleaner account separation makes tax time far easier.
Common Mistakes
Mistake #1: Missing the filing deadline.
Fix: If you miss the 2-month-15-day window, you can request late election relief using Form 2553 with a reasonable cause explanation (Rev. Proc. 2013-30 provides guidance)—the IRS grants this fairly often.
Mistake #2: Paying no salary or an unreasonably low salary to owner-employees.
Fix: Work with a CPA to benchmark a fair salary based on your role, industry, and local wage data before your first payroll run.
Mistake #3: Forgetting the state-level election.
Fix: Check your state’s Department of Revenue website immediately after filing federally to confirm whether an additional state form is needed.
Mistake #4: Mismatched business name or EIN on the form.
Fix: Pull your EIN confirmation letter (CP 575) and copy the business name exactly as it appears there.
Mistake #5: Not adjusting bookkeeping practices after conversion.
Fix: Set up separate general ledger accounts for salary, payroll tax expense, and shareholder distributions before your first quarter closes.
Next Steps
Once your S-corp election is approved:
- Set up quarterly estimated tax payments for the business, if applicable in your state
- File payroll tax returns (Form 941 quarterly, Form 940 annually) once payroll begins
- Issue W-2s to owner-employees and any staff by January 31 each year
- File Form 1120-S annually (the S-corp tax return) instead of Schedule C or Form 1065
- Issue Schedule K-1s to all members showing their share of income/distributions
- Revisit your salary annually with your accountant as your business income grows or shrinks
FAQ
Does converting to an S-corp change my LLC’s legal structure?
No. Your business remains legally an LLC with the same liability protections. Only your federal (and possibly state) tax treatment changes.
How much money do I need to be making to benefit from S-corp status?
Most tax professionals suggest S-corp election becomes worthwhile around $40,000–$60,000 in annual net profit, since payroll costs need to be outweighed by self-employment tax savings.
Can a single-member LLC elect S-corp status?
Yes. Single-member LLCs can absolutely elect S-corp taxation, though you’ll be both the sole owner and the required salaried employee.
What happens if I miss the deadline to file Form 2553?
You can request late election relief by filing Form 2553 late along with a statement explaining reasonable cause. The IRS approves most legitimate late election requests.
Do I need to file a new EIN application when converting to an S-corp?
No. Since your LLC’s legal entity doesn’t change, you keep your existing EIN—you’re simply changing your tax election, not forming a new entity.
