This is the **simple framework** that puts you in control of your **2026** bill, not scrambling in April. Watch the video above, then use this post as your worksheet. **Tool:** Need a quick calculator and deadlines? Open our **[Tax Playbook & Estimator](/resources/guides/tax-playbook)**. --- # 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. **Helpful:** Our **[Tax Playbook & Estimator](/resources/guides/tax-playbook)** compares safe‑harbor vs. rolling P&L estimates and maps your due dates. --- # 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. > The difference between overpaying and tax‑smart isn’t intelligence, it’s **structure and cadence**. --- # Your 2026 blueprint (printable checklist) - [ ] Calculate last year’s **effective rate** and note your state rate - [ ] Re‑check **entity fit** and owner compensation for 2026 - [ ] Turn on **Accountable Plan** reimbursements (policy + monthly form) - [ ] Lock a **monthly close** by the 15th (P&L, balance sheet, cash) - [ ] Track **mileage** and maintain a **depreciation** register - [ ] Schedule **quarterly** CPA check‑ins for estimates and strategy - [ ] Use the **[Tax Playbook & Estimator](/resources/guides/tax-playbook)** for dates and payment targets --- # What to do next **Simple start today:** Close your current books through last month and compute your effective rate. **Next step:** Pick **two** moves (entity/comp review + accountable plan) and implement this week. **Full service:** [Schedule a strategy session](https://www.havenstoneadvisory.com/schedule-consultation).
