Let’s talk about something more thrilling than a Tuesday night law class: your taxes. I know. You’d rather watch paint dry, or relive your CSLB exam. But stick with me, because this one’s actually about keeping money in your pocket instead of mailing it to a building in Washington D.C. you will never visit.
Here’s the deal. If you’re a licensed contractor in California running your business as a sole proprietor (or a single-member LLC that hasn’t elected anything fancy), you are currently handing over 15.3% of every single dollar of profit to something called self-employment tax. Not income tax. Not “oh that’s just normal.” An extra tax, on top of income tax, for the crime of being self-employed.
15.3 cents. Of every dollar. Before you even get to the “real” taxes.
If you’re the kind of contractor who reads bank statements and quietly weeps, this is the part where you sit up straight.

Wait, What’s the Difference Between a Sole Prop and an S-Corp Again?
Great question, hypothetical reader. A sole proprietorship is what happens by default when you start doing contractor work and don’t file any special paperwork with the IRS about how you want to be taxed. Congratulations, you’re a sole prop. It’s simple. It’s also expensive.
An S-corp isn’t even a different type of business — it’s a tax election. You (or an LLC you already have) can elect to be taxed as an S-corp, which means instead of the IRS taxing 100% of your profit at that 15.3% self-employment rate, you split your income into two buckets:
- A “reasonable salary” you pay yourself (still taxed the normal way)
- A “distribution” — the leftover profit, which skips the self-employment tax entirely
Same business. Same trucks. Same crew. Less money getting vacuumed out of your bank account every April.
The $60,000 Question
Here’s the part nobody tells you at the CSLB exam: this only makes sense once you’re actually making money. If you’re netting under about $60,000 a year, the cost of running payroll and filing a corporate return can eat up whatever you’d save. But once you cross that threshold — and a lot of licensed contractors blow past it fast — the math starts getting genuinely uncomfortable to ignore.
At $150,000 in net profit, we’re talking about potentially $10,000+ a year in savings. That’s not a rounding error. That’s a truck payment. That’s a crew member’s month. That’s a lot of In-N-Out.
Yes, California Still Wants Its Cut (Of Course It Does)
Because we live in California, nothing is ever quite that simple. The state charges S-corps a 1.5% franchise tax on net income, with an $800 minimum, every single year — a cost a sole prop doesn’t have. It’s real money, and if some slick sales pitch conveniently forgets to mention it, that’s a red flag bigger than a rooster at 6 a.m.
Here’s the honest version: for most contractors clearing that $60,000+ threshold, the federal savings from ditching the self-employment tax still blow right past what California takes back. But “still profitable after the state tax” and “the state tax doesn’t exist” are two very different sentences, and you deserve to hear the real one.
This is exactly why we built a calculator instead of just quoting you a round, suspiciously-convenient number. It runs the actual math — savings and costs, together — so you’re not finding out about California’s cut for the first time on your accountant’s invoice.
“But Won’t the IRS Audit Me More If I’m an S-Corp?”
This is the myth that keeps contractors stuck as sole props way longer than they should be, and it’s backwards. IRS Data Book figures show Schedule C sole proprietors get audited at roughly 2 to 4 times the rate of S-corps. Turns out the IRS’s automated red-flag system is way more suspicious of a guy reporting “Business Income” on his personal 1040 than it is of an actual corporate return. The paperwork you were avoiding because it seemed like “more scrutiny” is actually the paperwork that makes you look less interesting to an auditor.
The GC Handshake Test

Here’s the part that’s not about taxes at all: bidding as “ABC Construction, Inc.” reads completely differently to a general contractor, a lender, or a bonding company than bidding as “ABC Construction” with your own name on the DBA paperwork. It signals you’re an actual, structured business — not a guy with a truck and a dream (no offense to the guy with the truck and the dream, we were all that guy once).
It also gives you real liability protection, which a sole prop straight up does not have. If your business gets sued, a sole prop puts your house, your truck, your everything on the table. An S-corp puts a wall between “the business” and “your actual life.”
Okay, So What Do I Actually Do With This Information?
You do the math. Not “vibes math.” Actual math, based on your actual numbers, not some contractor forum guy’s numbers from four years ago.
We built a free calculator that takes your estimated annual profit and spits out your actual estimated savings — self-employment tax, the QBI deduction, minus what California’s extra S-corp franchise tax costs you — in about ten seconds. No account. No sales pitch upfront. Just your number.
