When to Convert Your LLC to S-Corp Status

The income threshold, decision framework, and process for making the S-Corp election. When it saves money and when it does not.

The Revenue Threshold: When S-Corp Makes Sense

Most tax professionals advise converting to S-Corp status when net business profit (after expenses but before the owner's compensation) consistently exceeds $50,000 to $80,000 per year. Below that threshold, the tax savings from the S-Corp structure are often smaller than the additional administrative costs.

Here is why the threshold exists. S-Corp administration adds approximately $1,500 to $3,500 in annual costs (payroll service, additional accounting fees, potential state fees). At $50,000 net profit, the S-Corp saves roughly $1,500 to $3,000 in self-employment tax depending on the reasonable salary chosen. The savings barely exceed the costs, making the decision marginal.

At $80,000 to $100,000 net profit, tax savings of $4,000 to $6,000 comfortably exceed the administrative costs. At $150,000 and above, the tax savings are substantial enough that virtually every tax professional recommends the S-Corp election.

Important caveat: these are general guidelines. Your specific threshold depends on your state (California's additional franchise tax makes the economics worse), the complexity of your business, and the actual costs your accountant charges for S-Corp preparation. Run the numbers for your specific situation before deciding.

The Salary Test: Setting a Reasonable Salary

Before electing S-Corp status, you need to understand what a reasonable salary for your role actually is. This requires research, not guesswork.

Methods for determining reasonable salary:

  • -Job boards and salary databases: search for your specific role and industry in your geographic area on sites like Glassdoor, LinkedIn Salary, Salary.com, and BLS occupational employment statistics
  • -Comparable business owner surveys: industry associations often publish compensation surveys for owner-operators in specific fields
  • -What you would pay to replace yourself: if you had to hire someone to do your job, what would you pay them?

Document your salary research and keep it with your business records. If the IRS ever questions your salary level, having documented comparables is critical. Working with a CPA who regularly handles S-Corp clients is the safest approach.

Common reasonable salary benchmarks by profession: freelance software developer ($70,000 to $130,000), marketing consultant ($60,000 to $90,000), accountant ($55,000 to $85,000), attorney ($80,000 to $140,000). These vary significantly by location, specialisation, and years of experience.

How to Make the S-Corp Election

If you already have an LLC, you do not need to form a new entity. You file Form 2553 (Election by a Small Business Corporation) with the IRS to elect S-Corp taxation for your existing LLC. The process:

  1. 1.Confirm you meet S-Corp eligibility requirements: you must be a US citizen or permanent resident, have no more than 100 shareholders (just you in a single-member LLC), and have only one class of stock/ownership interest.
  2. 2.File Form 2553 with the IRS. To be effective for the current tax year, this must be filed by March 15 of that year (or within 75 days of forming the LLC, if electing at formation). Late elections may be accepted with reasonable cause, but do not rely on this.
  3. 3.Set up payroll for yourself. You must run payroll and withhold taxes from your own salary. Services like Gusto, ADP, or QuickBooks Payroll can handle this for $50 to $150 per month.
  4. 4.Work with a CPA to prepare Form 1120-S (S-Corp tax return) annually in addition to your personal return.

Costs of Converting

The one-time and ongoing costs of making the S-Corp election:

Cost ItemOne-TimeAnnual Ongoing
CPA fee to file Form 2553$200 - $500-
Payroll serviceSetup: $0 - $100$600 - $1,800
Additional accounting (1120-S)-$500 - $1,500
State fees (varies by state)$0 - $500$0 - $800
Total estimated$300 - $1,100$1,100 - $4,100

When NOT to Convert: Common Scenarios

The S-Corp election is not always the right move. Situations where staying as a default LLC makes more sense:

  • -Profits consistently below $50,000 to $60,000: the costs exceed the savings
  • -Business is in California: the $800 minimum franchise tax plus additional S-Corp costs make the breakeven higher
  • -You want to bring in investors: S-Corps cannot have more than 100 shareholders and cannot have non-US citizen shareholders. If you plan to raise VC money, keep an LLC or form a C-Corp instead
  • -Income is highly variable: if your profit fluctuates significantly year to year, the administrative burden of S-Corp maintenance may not be worth it in low-income years
  • -You want to keep things simple: the LLC structure requires far less paperwork, fewer filings, and lower accounting complexity
