S-corp election in Colorado: when the math actually pays off.

Reasonable comp, $50K thresholds, payroll setup costs, and the hidden Colorado-specific wrinkles that change the answer.

By Kali Gilliland · April 18, 2026

The S-corp election is the most discussed tax move in small business — and the most poorly understood. Half the owners we meet think they need to make the election the day they form an LLC. The other half avoid it for years past the point it would have saved them five figures. The right answer depends on real numbers, not rules of thumb pulled from a podcast.

We have run the S-corp election math for Colorado small businesses across trades, eCommerce, real estate, and professional services. The break-even point is more nuanced than the common "$40K rule" suggests. Here is what the math actually looks like.

What the S-corp election actually does

An S-corp is a tax election, not an entity type. You can elect S-corp status on top of an LLC or a corporation. The change is in how the IRS treats your earnings:

  • As a sole proprietor or default LLC: all profit is hit with self-employment (SE) tax — 15.3% on the first ~$168,600 of earnings (2024 cap, 2026 will be higher), then 2.9% Medicare on everything above.
  • As an S-corp: you pay yourself a "reasonable" W-2 salary. SE-tax-equivalent payroll tax (FICA) hits the salary only. Profit above the salary is distributed to you as distributions, which are not subject to SE/payroll tax.

The savings come from the spread between net profit and reasonable salary. The catch is "reasonable" — the IRS expects your salary to reflect what you'd pay someone else to do the work you do. Pay yourself $5,000 on a $200,000 net and the IRS will reclassify and assess back-payroll-tax with penalties.

The actual break-even, modeled

The election only makes sense once the SE tax savings exceed the cost of running an S-corp. Those costs are real:

CostAnnual range
Payroll setup & processing (Gusto / QBO)$600 – $1,500
Form 1120-S preparation$1,200 – $2,500
State franchise / minimum tax (CO has no franchise tax — $0)$0 in Colorado
Unemployment insurance on owner wages$200 – $700
Workers comp on owner wages (if not exempt)$200 – $1,500

Total carry cost in Colorado typically runs $2,200 to $5,000 per year. The election starts to save real money once SE-tax savings clear that threshold by a comfortable margin.

Here is the math at three income levels (assuming reasonable salary set at 50% of net, 2024 SE tax rates):

Net profitSE tax savedS-corp carry costNet annual benefit
$60,000~$4,590~$3,000~$1,590
$100,000~$7,650~$3,500~$4,150
$150,000~$11,475~$3,800~$7,675
$250,000~$14,000+~$4,200~$9,800+

Real-world break-even sits around $60,000 to $80,000 in net profit for most service businesses. Below that, the carry cost eats too much of the SE savings. Above $100K, the election is almost always worth doing.

Field note from a 2025 election

A general contractor doing $185,000 net as a single-member LLC was paying about $23,500 in SE tax. We elected S-corp retroactive to January 1 (Form 2553 plus late-election relief), set salary at $78,000 with the rest as distribution, and ran first-year payroll through Gusto. SE-tax savings: $13,800. S-corp carry: $3,400. Net first-year benefit: $10,400 — and the savings repeat every year.

Reasonable comp: the line that matters

The IRS does not publish a formula. Reasonable comp is what you would pay someone else to do your job. The factors that hold up under audit:

  • Industry compensation surveys (BLS, RCReports — we use the latter for client filings).
  • Time allocation between owner work and management work.
  • Comparable salaries in your geography (Denver-metro construction-trade owners typically anchor at $70K–$110K depending on revenue).
  • Distribution of duties — if you're 80% on the tools and 20% running the business, you can't argue most of your pay is "owner profit."

The audit risk is real but rare. The IRS targets returns where the salary is so low it triggers an obvious mismatch — e.g., a $300K net company paying the owner $15,000 and distributing $285,000. Set salary in a defensible band (often 35–55% of net for service businesses, 25–40% for capital-intensive or materials-heavy businesses), document the methodology, and move on.

Decision matrix

If / Then

If your net profit is under $60,000, hold off. The carry cost outweighs SE savings.
If your net is $60K–$100K and you have predictable income, run the election math but expect modest first-year savings.
If your net is consistently above $100K, the election almost always wins. Schedule it.
If you are unsure on your net, get the books current first. The election decision needs accurate numbers, not estimates.

The Colorado-specific wrinkles

  • No state franchise tax. Colorado does not impose a flat S-corp tax — your state-level cost is just the small business income filing. This makes Colorado one of the more S-corp-friendly states.
  • Workers comp on owner wages. Colorado allows working owners to be excluded from workers comp coverage in many trades. Election varies — confirm with your insurer.
  • Pass-through-entity tax (PTET). Colorado offers an elective entity-level tax that workarounds the federal SALT cap for some pass-through owners. Worth modeling if you itemize and you're in the 32%+ federal bracket.
The Bottom Line

Run the math at $60K, decide at $80K, definitely elect at $100K.

The S-corp election saves real money — but only when the carry cost is justified. We model the actual numbers for your situation, file the election, and set up payroll in one engagement.

Frequently asked questions

Can I elect S-corp status mid-year?

The general rule: Form 2553 must be filed within 2 months and 15 days of the start of the tax year you want the election to take effect. Late-election relief under Rev. Proc. 2013-30 lets you elect retroactively if you have reasonable cause and have been filing as if you were already an S-corp. We file late-election requests routinely — most are accepted.

What about LLC vs S-corp on the entity side?

You do not have to choose — most clients are an LLC that has elected to be taxed as an S-corp. The LLC gives you state-level liability protection; the S-corp election changes federal tax treatment. Best of both.

Do I need to run actual payroll, or can I just take draws?

You must run actual payroll. An S-corp owner-employee gets a W-2 like any other employee, with FICA withholding, federal and state income tax, unemployment insurance, etc. Just taking draws and skipping payroll defeats the election.

How much should my salary be?

"Reasonable" varies by industry and revenue. For Denver-metro service-business owners, common ranges are 35–55% of net profit. We use RCReports or industry benchmarks to set defensible numbers and document the methodology in case of audit.
