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.
