The quick take

• The IRS doesn’t care that you formed an LLC; it cares how it’s taxed and how you run it.
• Filing out‑of‑state rarely saves tax if you operate at home, and can add fees and risk.
• Staying in the default tax treatment for too long is what quietly costs five figures.
• Your protection fails if you commingle funds or ignore basic compliance.

The 6 costly LLC mistakes (and fixes)

1) Treating formation as the strategy

A few clicks and $200 later, you “feel official.” But documents ≠ design. The savings and protection are decided after formation.

Fix: Plan the tax election, compensation approach (if S Corp later), banking, and bookkeeping before money flows.

2) False protection trap (commingling)

One bank account for everything, no updated operating agreement, and no paper trail. On paper you have an LLC; in practice, courts/IRS may ignore it.

Fix: Separate bank/credit accounts, written operating agreement, monthly close, and an Accountable Plan for owner reimbursements.

3) The Wyoming/Delaware myth

You live and operate in State A but form in State B to “save tax.” You likely owe tax in State A anyway and may have to register as a foreign LLC, more fees, more filings, more chances to miss something.

Fix: File where you operate unless a specific legal reason justifies otherwise. Simpler usually wins.

4) Staying in the default too long

Default solo‑owner LLC becomes a disregarded entity reported on Schedule C. Simple at first, but every dollar of profit is exposed to self‑employment tax (~15.3%) plus income tax.
At $50k profit, that’s ~$7.6k SE tax; at $150k, ~$20k; at $250k, $30k+ (approx., fact‑dependent).

Fix: When profit is sustained around $60k–$100k+, model an S Corp election. Pay a reasonable W‑2 salary; take the rest as distributions (not subject to SE tax). Weigh savings vs. payroll/admin costs.

5) Copy‑pastable ‘multiple LLCs’ with no intent

Three, four, five LLCs, still overpaying and under‑protected because none are designed with purpose (banking, agreements, inter‑company flows).

Fix: Start with one clean, intentional structure. Add entities only when there’s a clear business, legal, or tax reason.

6) No maintenance = no protection

Late filings, stale agreements, no minutes/consents (when required), and expenses run sloppily through personal cards.

Fix: Calendar renewals, keep resolutions/consents, reconcile monthly, and route spend through business accounts with receipts.

What the IRS actually cares about

1. Tax classification (default Schedule C/partnership vs. S Corp/C Corp).
2. Operational reality (separate finances, books, documentation, payroll if required).

That’s what drives your tax bill and whether your structure holds up.

Owner A vs. Owner B (same income, different outcome)

• Owner A: Out‑of‑state filing, default tax forever, mixed funds. ~$220k income, $30k+ in avoidable SE tax exposure annually, weak protection.
• Owner B: Filed in‑state, separated accounts, switched to S Corp at ~$80k sustained profit, documented reasonable compensation. Same income, $40k–$50k more kept each year. Over five years: $200k+ delta.

The 3 control points (simple, not simplistic)

1. Operating state: File where you live and operate (unless a targeted legal reason says otherwise).
2. Tax election: Default may be fine early; once profit is steady (~$60k–$100k+), evaluate S Corp with your CPA.
3. Compliance habits: Separate banking, clean books, on‑time filings, updated operating agreement, and a real reimbursement policy.

If any one is weak, the structure weakens. Two or more, and money starts leaking.
