Small Business Tax Planning
Done Right All Year
Most small business owners focus on taxes in April. Winners plan in January, June, September, and December. We build a roadmap so you know exactly what moves to make each quarter to maximize deductions and minimize your bill.

Year-Round Planning Philosophy
The proactive vs. reactive divide
The difference between a business owner paying $50K in taxes and one paying $25K isn't luck—it's timing. Proactive tax planning means making decisions throughout the year that compound into real savings.
Proactive planning flips this on its head. We meet in January (or sooner) to understand your income trajectory, business structure, and goals. Then we create a quarterly action plan: specific moves in Q1, Q2, Q3, and Q4 that legally reduce your tax bill.
Entity Optimization Strategy
Choosing the structure that saves the most
Entity structure is the single biggest tax lever for small business owners. A $300K profit business can owe anywhere from $60K to $90K in taxes depending solely on whether it's a sole proprietorship, LLC, or S-Corporation.
The Entity Comparison
| Entity Type | Self-Employ Tax | Setup Cost | Annual Complexity | Best For |
|---|---|---|---|---|
| Sole Proprietorship | 15.3% on all net income | $0 | Low (Schedule C) | Side gigs, sole contractors |
| LLC (Default Taxed as SP) | 15.3% on all net income | $150-300 | Low (Schedule C) | Passive liability protection |
| LLC Taxed as S-Corp | 0% on distributions + SE tax on "reasonable" salary | $800-1,500 | High (Form 1120-S, payroll) | $100K+ profit. SAVES 15-25% |
| C-Corporation | 0% (taxed at entity level) | $500-1,000 | High (Form 1120, payroll) | Rarely optimal for small biz |
We recommend most small businesses structure as an LLC (for liability protection) and elect S-Corp taxation (for SE tax savings). This hybrid approach gives you personal asset protection plus aggressive tax optimization.
Reasonable Salary & Distributions
The IRS requires one, but permits the other
In an S-Corporation, you split your income into two buckets: (1) W-2 salary (subject to payroll taxes), and (2) distributions (NOT subject to self-employment tax). The IRS only allows this if your W-2 salary is "reasonable."
Reasonable Salary Example
Business Net Profit: $250,000
Reasonable W-2 Salary: $150,000 (market rate for your role)
Distributions: $100,000 (remaining profit, NOT subject to SE tax)
SE Tax Savings: $100,000 × 15.3% = $15,300 saved annually
The key is documentation. Keep salary surveys for your industry, track your hours, and maintain P&L statements that justify the salary level. The IRS looks at three factors: (1) industry standards, (2) business profitability, and (3) shareholder equity.
Tax Planning Calendar (Q1–Q4)
Specific actions for each quarter
This is your operational roadmap. These aren't suggestions—these are deadlines and action items that compound into major tax savings.
Q1 (Jan-Mar)
- ✓File prior year return + pay balance due or claim refund
- ✓Decide entity structure (S-Corp, LLC, SP) for the year
- ✓Set up payroll system if S-Corp
- ✓Review income projection for the year
- ✓Begin quarterly estimated tax payments if self-employed
Q2 (Apr-Jun)
- ✓Make Q2 estimated tax payment (if applicable)
- ✓Review Q1 P&L and adjust income projection
- ✓Maximize pre-tax retirement contributions (solo 401k, SEP-IRA)
- ✓Evaluate S-Corp payroll: is salary reasonable?
- ✓Plan summer business expenses/purchases
Q3 (Jul-Sep)
- ✓Make Q3 estimated tax payment
- ✓Review 6-month P&L; project year-end taxable income
- ✓Discuss year-end strategies: entity elections, equipment purchases
- ✓Evaluate charitable giving strategy for year
- ✓Start planning Q4 aggressive tax moves
Q4 (Oct-Dec)
- ✓Maximize equipment purchases (Section 179, bonus depreciation)
- ✓Max out retirement contributions (deadline often Jan 15 next year)
- ✓Execute charitable giving if applicable
- ✓Verify payroll is correct; adjust if needed
- ✓Final income projection and tax payment estimate
- ✓Begin tax preparation conversations (file by Apr 15)
Retirement Contribution Strategies
Shelter $60K–$300K+ in income annually
Retirement plans are the government's favorite tax incentive. Fund them aggressively, and you reduce taxable income while building personal wealth. The right plan can shelter $60,000–$300,000+ annually depending on business structure and income.
Retirement Plan Options for Small Business
Solo 401(k)
Best for sole proprietors and single-owner S-Corps. Can contribute up to $69,000 in 2024 (or $76,500 if 50+). Low setup cost, self-directed investment options.
SEP-IRA
Simplest to administer. Can contribute 25% of net SE income (up to $69,000). Good for businesses that scale since contributions grow with income.
Cash Balance Plan
Most aggressive. Allows $175,000–$300,000+ annual contributions for higher-income business owners. Requires actuarial calculation and more complex administration.
We coordinate retirement contributions with income projections. If your business is having a good year, we maximize contributions to reduce taxable income. If it's a slower year, we adjust to maintain flexibility.
Section 179 & Equipment Timing
Immediately deduct up to $1.22M in purchases
Section 179 expensing is a legal tax loophole. Instead of depreciating equipment over 5-7 years, you can deduct the full purchase price in the year you buy it. Combined with bonus depreciation, this creates massive deductions for good-income years.
Section 179 Key Limits (2024)
- • Deduction Limit: $1,220,000 total purchases (indexed annually)
- • Phaseout Threshold: Purchases over $4,880,000 reduce your deduction
- • Qualifies: Machinery, equipment, computers, vehicles (with limits), furniture, software
- • Does NOT Qualify: Buildings, land, certain vehicles, items used partly personally
- • Must Be: New or used property acquired for active business use
Bonus depreciation (100% in 2024, phasing down) stacks on top of Section 179. The key is timing: if you're projecting a high-income year, accelerate equipment purchases into December to capture deductions. If it's a low year, defer purchases to next year.
Hiring Family Members
Income splitting with legitimate business purpose
Hiring a spouse, child, or parent can reduce your self-employment taxes while providing them with income and building their credit/Social Security record. But the IRS scrutinizes this heavily, so it must be legitimate.
Kid Hiring Benefits
Tax Savings: $10,000 kid income × 20% tax avoidance = $2,000/year saved. Over 10 years, that's $20,000+ in tax avoidance plus compounding investment growth.
Income Splitting: You reduce your taxable income, they build a low-tax income. If they have no other income, their earnings up to the standard deduction ($14,600 in 2024) are entirely tax-free.
Social Security: They begin building a Social Security record, which matters for future disability/retirement benefits.
Work Ethic: They learn business operations and financial responsibility.
We also use the "Augusta Rule" strategy for home-based businesses: rent your home to your business for legitimate business purposes (client meetings, work-from-home office), and deduct allocable mortgage interest, utilities, insurance, and depreciation. Combined with family hiring, this can save 25-35% in taxes for home-based entrepreneurs.
Implementation & Next Steps
From strategy to execution
Reading about tax strategies is one thing. Actually implementing them is another. Here's how we turn this roadmap into real tax savings.
Our Tax Planning Process
Initial Assessment
We review 2-3 years of tax returns, understand your business model, income trajectory, and risk tolerance. No two businesses are identical.
Strategy Design
We model multiple scenarios (entity type, retirement contributions, equipment timing) and calculate projected savings for each. You get a written tax plan with dollar estimates.
Quarterly Meetings
We meet in Jan, June, Sept, and Dec to review projections, adjust strategies, and execute time-sensitive moves. You're never flying blind.
Year-End Push
October–December is where we execute the big moves: equipment purchases, retirement contributions, charitable giving, and entity elections. All coordinated for maximum impact.
Tax Preparation & Filing
By April, we file your return. But the real work is done. You've already captured 90% of available deductions and implemented all key strategies.
