The quick take

• Taxes aren’t just “federal.” They stack (federal, self‑employment/payroll, state, local).
• Entity determines where your profit lands, and income type determines how it’s taxed.
• A light, 5‑step plan + a few boring habits beats last‑minute heroics.

---

1) How taxes actually stack

Most owners only think “federal income tax.” In reality you also face:

• Payroll/Self‑employment tax on salary or guaranteed payments
• State income tax and, in some places, local/city taxes

Mental model: revenue − expenses = profit, and profit is what gets taxed.
Example: $1,000,000 revenue − $600,000 expenses = $400,000 profit. Depending on your rates, a combined burden around one‑half of profit means ~$200,000 in taxes. Your exact number varies—this is why strategy matters.

---

2) Entity types change the outcome

Your entity controls how profit flows to returns:

• Pass‑throughs (sole prop/LLC, partnerships, S‑Corps): profit flows to your 1040.
• C‑Corp: pays its own tax; shareholder dividends are taxed again (double tax). Benefits can be powerful, but planning is essential.

Fit matters: mis‑matched entity choice can add avoidable tax or admin. Re‑evaluate when margins, headcount, or goals change.

---

3) Not all income is taxed the same

• Earned/active (W‑2 wages, guaranteed payments, Schedule C): includes payroll or self‑employment taxes—often the highest‑cost income.
• Portfolio/capital (long‑term gains, qualified dividends): often lower rates and more control over timing.
• Passive real estate: depreciation and grouping rules can reduce current tax even with real cash flow.

Beginner takeaway: you don’t have to shut down your business to lower taxes—shift more income into smarter categories as you grow.

4) Filing basics (what forms connect to your books)

Everyone files Form 1040. The attachments depend on your activity:

• Sole proprietor: Schedule C
• Rentals: Schedule E
• S‑Corp: Form 1120‑S (plus K‑1 to you)
• C‑Corp: Form 1120

Your CPA needs accurate books—updated before year‑end, with clean support—so these numbers flow correctly.

5) Build your simple 2026 plan (5 steps)

1. Know your rates: Calculate last year’s effective rate (total tax ÷ taxable income). Note your state rate, too.
2. Pick 1–2 high‑impact strategies: e.g., entity/comp review, retirement contributions, or trust/estate planning if appropriate.
3. Manage timing: accelerate expenses you truly need; defer some revenue where appropriate, consistent with your accounting method.
4. Install systems: accountable plan, expense policies, accurate bookkeeping, mileage logs, and documentation for each deduction.
5. Quarterly cadence: meet your advisor each quarter to update estimates and adjust—no April surprises.

Quick wins most owners miss

• Separate personal and business finances completely (bank accounts and cards).
• Keep a fixed‑asset and depreciation schedule for major buys.
• Choose standard mileage or actual for vehicles and track correctly.
• Adopt an Accountable Plan so reimbursements (home office, phone, internet, mileage) are clean and documented.
• If you’re an S‑Corp, set reasonable compensation to avoid overpaying payroll taxes or raising red flags.
