You’ve done the math. Maybe you ran it through our calculator. Maybe you did it on a napkin at lunch. Either way, you’ve landed on the same conclusion a lot of profitable California contractors land on: staying a sole prop is costing you real money every year.
Good. Now let’s talk about how you actually get from where you are to where you want to be — because “convert to an S-corp” isn’t one step. It’s a sequence, and the order matters. Skip one, or do them out of order, and you can blow the timing on the whole year.
Here’s the real order of operations, no fluff.
Step 1: Confirm the Math Actually Works for You
Before any paperwork gets filed, know your number. As a rule of thumb, S-corp savings start to make sense once you’re netting around $60,000+ a year — below that, the cost of payroll and a corporate return can eat whatever you’d save. Run your specific numbers before you spend a dollar on this: use the free S-Corp Savings Calculator and see where you actually land.
Step 2: Set Up (or Confirm) Your Legal Entity
Here’s the part that surprises people: an S-corp isn’t a business type. It’s a tax election sitting on top of an actual legal entity — either an LLC or a corporation. If you’re currently a true sole prop with zero entity on file, you’ll file Articles of Organization (for an LLC) or Articles of Incorporation (for a corporation) with the California Secretary of State first. Already have an LLC? Skip straight to Step 3.
Step 3: Get Your EIN
Free, from irs.gov, takes about ten minutes. Sole props often run everything under their own Social Security number — that stops here. Your EIN becomes the identity your business operates under from now on: bank account, payroll, every tax filing.
Step 4: File Form 2553 — This Is the Actual Election
This is the step people miss the deadline on, and it’s the one that actually makes you an S-corp for tax purposes. Form 2553 has to reach the IRS within 2 months and 15 days of the start of the tax year you want the election to apply to. Miss that window and you’re waiting until next January — which means paying full self-employment tax on this year’s profit while you wait.
Step 5: Set Up Payroll (Yes, Payroll, For Yourself)
Once the election is in place, you’re legally required to pay yourself a “reasonable salary” through actual payroll — tax withholding, W-2, all of it. This is where the strategy either works or backfires. Pay yourself too little relative to your profit, and you’re the exact pattern the IRS looks for. Getting the salary-versus-distribution split right is the whole game.
Step 6: Update Your CSLB License, Bond, and Bank Accounts
Almost every contractor forgets this one. Your license, your bond, your insurance, and your business bank account all need to reflect the new entity — not your old sole-prop information. CSLB needs to know who’s actually operating under that license number, and a mismatch here is the kind of thing that turns into a real headache later, not just paperwork.
Step 7: File Your Corporate Return — Every Year, From Here On
Instead of a Schedule C tucked into your personal return, you’re now filing Form 1120-S federally and Form 100S in California, plus that 1.5% (or $800 minimum) California franchise tax that comes with the territory. More paperwork, yes. But it’s also the paperwork that, per IRS data, gets audited at a lower rate than the sole-prop return you’re replacing.
How Long Does This Actually Take?
Realistically: entity formation can take a couple weeks with the state, the EIN is instant, and Form 2553 processing varies — but the clock that actually matters is that 2-month-15-day election deadline, not how fast the paperwork moves. Start early. Waiting until you “have time” is how contractors miss a full tax year of savings.
