When an S Corp Starts Making Sense
As a sole proprietor or single-member LLC, every dollar of net profit from your web design business gets hit with self-employment tax: 15.3% for Social Security and Medicare, reported on Schedule SE alongside your Schedule C. An S corp lets you split your income into two buckets: a reasonable salary (subject to payroll tax) and distributions (not subject to self-employment tax). That split is the entire reason people form S corps.
The catch is the IRS requires you to pay yourself a "reasonable salary" for the work you actually do, comparable to what you'd pay an employee doing the same job. You can't pay yourself $10,000 and call the other $90,000 a distribution just to dodge payroll tax. So the savings only show up on the gap between your reasonable salary and your total profit.
Most tax professionals point to somewhere between $60,000 and $80,000 in consistent annual net profit as the point where the math starts favoring an S corp. Below that, there usually isn't enough of a gap to justify the added cost and complexity.
The Costs and Trade-offs You're Signing Up For
An S corp isn't a separate legal entity, it's a tax election you make on top of an LLC or corporation using Form 2553. Once elected, you take on real obligations:
- Running actual payroll for yourself, including withholding and filing Form 941 quarterly and W-2s at year-end
- Filing a separate business tax return, Form 1120-S, in addition to your personal Form 1040
- Paying for bookkeeping or an accountant who understands payroll compliance, since messing up reasonable compensation is a common audit trigger
- Potential state-level fees or franchise taxes depending on where you're based
- Less flexibility if your income swings wildly, since payroll runs regardless of a slow month
For freelance web designers with feast-or-famine invoicing, that last point matters. If your income is unpredictable, committing to a fixed payroll schedule can create cash flow headaches you didn't have as a sole proprietor.
How to Actually Decide
Start by looking at your last 12 months of net profit, not gross revenue. If you're consistently clearing $30,000 to $50,000 after expenses, the S corp election probably costs you more in accounting fees and administrative time than it saves. If you're clearing $80,000 or more and expect that to hold steady, run the numbers: estimate a reasonable salary for a web designer with your experience, then calculate the self-employment tax you'd save on the remaining profit paid as distributions. Compare that savings to the extra cost of payroll processing and a separate business return.
Also consider timing. You don't have to decide this in your first year of freelancing. Many designers stay a sole proprietor or single-member LLC until income stabilizes, then elect S corp status once the numbers clearly justify it. The election can be made for the current tax year if filed early enough, or you can plan for it starting the following January.
If you're unsure where your numbers land, a session with a tax professional who can model both scenarios against your actual invoicing history is worth more than any general rule of thumb.
