Incorporation Choices for Service Businesses

Why this matters

The legal structure of a service business affects taxes, liability, hiring, financing, + exit options for the entire life of the company. The wrong choice early on can cost an owner + over a few years in unnecessary tax + administrative overhead. Most contractors form an LLC by default - sometimes that's right + sometimes it's leaving a lot of money on the table. This is the working reference. Not legal advice; consult a CPA + attorney for your specific situation.

The four structures field-service operators see

Sole Proprietorship

• Default if you operate under your own name without filing
• No separate legal entity
• Personal liability for ALL business debts + lawsuits
• Income flows to personal return on Schedule C
• Subject to full self-employment tax (~15.3%)
• Worst for liability + tax efficiency

Rare to recommend for any service business with employees, vehicles, or material liability exposure.

Single-Member LLC (SMLLC)

• Legal entity separate from owner
• Liability protection (creditors generally can't reach personal assets)
• Default tax treatment: same as sole prop (Schedule C, full self-employment tax)
• Simple admin (no separate tax return needed by default)

The default for new contractors. Liability protection + easy admin.

Multi-Member LLC

• Same as SMLLC but with multiple owners
• Operating agreement defines ownership + profit splits
• Files separate partnership tax return (Form 1065) + each owner gets K-1
• Self-employment tax on each owner's distributive share

For partnerships.

S-Corp Election (NOT a separate entity - a TAX ELECTION)

• An LLC OR corporation can elect S-Corp tax treatment with IRS Form 2553
• Owner becomes "shareholder-employee" of the entity
• Owner pays themselves a "reasonable salary" via W-2 payroll
• Additional profit distributions are NOT subject to self-employment tax
• This is the BIG TAX SAVINGS for profitable contractors
• Requires payroll setup + separate 1120-S tax return

C-Corporation

• Separate taxable entity (pays corporate tax)
• Double-taxation: profits taxed at corp level + dividends taxed at personal level
• Rare for small service businesses
• Used when: outside investors, very high reinvested profits, multi-class shares

The S-Corp tax savings math (the most-asked question)

Self-employment tax: 15.3% on net business income up to Social Security wage base, then 2.9% above that.

LLC default treatment: ALL net profit subject to self-employment tax.

S-Corp election: only the "reasonable salary" portion subject to FICA payroll tax (employee + employer side = 15.3% total). Profit distributions above salary = NO self-employment tax.

Example: Service business net profit = .

LLC default:

**S-Corp with "reasonable salary" of **:

• Federal + state income tax: same as before

After accounting for the additional ~ in admin (payroll service + S-Corp tax return), net annual savings: ~.

This is real money. Compounds over years.

When S-Corp election makes sense

Yes if:

• You can defend a "reasonable salary" (IRS scrutiny: salary must be reasonable for the work performed)
• You're committed to running payroll properly

Probably not if:

• You're a brand-new business uncertain of profit
• You don't want payroll admin complexity

Maybe not yet if:

Reasonable salary (the IRS scrutiny point)

S-Corp election requires the owner-employee to pay themselves a "reasonable salary" - not zero, not minimum wage. The IRS uses this rule to prevent owners from skipping FICA tax by paying themselves .

What's "reasonable"? Comparable wages for similar work at similar businesses. For most service-business owners:

• Average tech wage in their market for someone with their skill level
• Industry comparable for similar-size company
• Documented logic + supporting comp data

Aim for 30 - 50% of net income as salary, balance as distribution. Be conservative (higher salary) if you want low IRS attention; be aggressive (lower salary) only if you have strong documentation.

CPA can help size the salary defensibly.

Liability protection - what it ACTUALLY does

Creditors of the business generally can't reach personal assets. Exceptions ("piercing the veil"): personal guarantee on loans, co-mingled funds, fraud / negligence / criminal acts, owner's direct personal involvement, inadequate capitalization.

Works best with: separate bank account (mandatory), separate credit card (mandatory), no co-mingling, adequate insurance, proper paperwork (annual reports, operating agreement). Meaningful but not absolute - backstop to good insurance, not replacement.

State considerations

CA. TX: no state income tax; high franchise threshold. NY: publication requirement . FL: low cost, popular for relocation. Operate in multiple states = register as foreign entity in each.

Cost summary

The transition: LLC to S-Corp election

You don't need to dissolve + recreate. File IRS Form 2553 (the S-Corp election). Best timing:

• Filed by March 15 for current tax year
• Filed for late-year start (October - December): file Form 2553 + appropriate retroactive election letters
• CPA handles this paperwork

Most contractors switch from LLC default to S-Corp election in year 2 - 4 once profit is consistent.

Multi-entity (holding company)

At M+ revenue OR specific risk concerns: holding LLC owns operating LLC + real estate LLC. Operating leases from real estate LLC. Appreciation outside liability exposure. Below M, complexity exceeds benefit.
