6 Tax Planning Strategies Every Small Business Owner Should Be Using

Strategy 1: Optimize Your Entity Structure

The most impactful single tax decision most small business owners can make is choosing the right entity structure — and the most common mistake is operating as a sole proprietor or single-member LLC (taxed as a sole proprietor) when an S-Corp election would save substantially more.

Here is why: Sole proprietors pay self-employment tax (15.3% on the first ~$160K, 2.9% above that) on every dollar of net income. An S-Corp owner pays a reasonable salary — subject to payroll taxes — and takes the remaining income as a distribution, which is not subject to SE tax. The difference can be enormous.

The S-Corp requires a reasonable salary determination, payroll setup, and additional administrative overhead — but the annual savings almost always far exceed the costs at the income levels shown. The deadline to elect S-Corp status for the current tax year is March 15. For a detailed analysis: LLC vs. S-Corp for Contractors: Which Structure Saves More?

Strategy 2: Maximize Retirement Plan Contributions

Retirement plan contributions are the most powerful deduction available to small business owners — and the most consistently underused. Here is what is available:

• SEP IRA: Up to 25% of net self-employment income, maximum $66,000 (2023). Simple to establish, no annual filing requirements, contributions can be made up to the tax filing deadline including extensions. Best for businesses without employees.
• Solo 401(k): Employee deferral ($22,500 in 2023, plus $7,500 catch-up if 50+) plus employer profit-sharing (up to 25% of W-2 wages). Total maximum $66,000/$73,500. Requires a plan document and annual Form 5500 when assets exceed $250,000. Plan must be established by December 31 of the contribution year.
• Defined Benefit Plan: For higher earners ($300,000+), a defined benefit plan can allow $100,000–$275,000+ in annual contributions. Actuarially calculated each year. Significant administrative cost but can eliminate a massive amount of taxable income for owners in their peak earning years.
• SIMPLE IRA: For businesses with employees; employee deferrals up to $15,500 (2023) plus mandatory employer match.

At a 35% combined tax rate, contributing the maximum $66,000 to a retirement plan saves $23,100 in current-year taxes while building long-term wealth. This is not a deferral — it is a real reduction in your tax bill. For a full comparison: Best Retirement Plan Options for the Self-Employed.

Strategy 3: Time Income and Expenses Strategically

Tax liability is determined by when income is received and when expenses are paid — not just how much. Cash-basis taxpayers (which most small businesses are) have some ability to control the timing of income recognition and expense deductions, and doing so strategically can make a significant difference.

Income Timing Strategies

• Defer December invoices to January if you expect to be in a lower bracket next year — income recognized in January is taxable in the next year
• Accelerate December invoices if you expect higher income next year and want to fill a lower bracket this year
• Installment sales allow recognition of gain from business asset sales over multiple years rather than all in one year

Expense Timing Strategies

• Equipment purchases: Buy and place equipment in service before December 31 to capture Section 179 deductions in the current year — or defer to next year if income is low this year
• Prepaid expenses: Paying next year's rent, insurance, or subscriptions before December 31 may be deductible in the current year (the 12-month rule applies)
• Accounts payable: Paying outstanding vendor invoices before year-end accelerates the deduction into the current year

Strategy 4: Split Income Through Family Employment

The U.S. progressive tax system means that income taxed in lower brackets is taxed at lower rates. Family employment strategies allow small business owners to legitimately shift some income from high brackets to lower ones — reducing the family's total tax burden.

Employing a Spouse

Paying your spouse for legitimate work (bookkeeping, administrative work, marketing, client coordination) creates a deductible business expense. Your spouse can then fund their own retirement account, getting additional tax-deferred savings. If your spouse has no other significant income, their effective tax rate may be much lower than yours — creating a permanent tax reduction, not just a deferral.

Employing Children

Children employed by a parent-owned sole proprietorship or partnership (not S-Corp or C-Corp) who are under 18 are exempt from FICA taxes. The child can earn up to the standard deduction ($14,600 in 2024) with no federal income tax. For real, legitimate work (filing, cleaning, helping with marketing or social media), this can save $5,000–$8,000 per year per child at the owner's marginal rate.

Critical requirement: The work must be real and the pay must be reasonable. Keep records of hours worked, tasks performed, and payments made. The IRS scrutinizes family employment arrangements — proper documentation is non-negotiable.

Strategy 5: Implement an Accountable Plan

An accountable plan is an IRS-compliant expense reimbursement policy for businesses. It allows S-Corp and C-Corp owner-employees to receive tax-free reimbursements for legitimate business expenses without those reimbursements being treated as taxable W-2 income.

Without an accountable plan, an S-Corp owner who pays home office expenses, vehicle expenses, or professional development out of pocket is losing those deductions entirely — or taking them as unreimbursed employee expenses (which are no longer deductible since 2018 for most employees).

What an Accountable Plan Covers

• Home office expenses (the business-use percentage of rent/mortgage, utilities, insurance)
• Vehicle expenses (mileage reimbursement at the IRS standard rate, or actual vehicle costs)
• Professional development, conferences, and continuing education
• Business-related cell phone and internet
• Meals and entertainment meeting the business purpose standard
• Professional supplies and equipment under the expensing threshold

Requirements for a Valid Accountable Plan

• Written plan document adopted by the corporation
• Business connection for all reimbursed expenses
• Adequate accounting (receipts, expense reports submitted within a reasonable time)
• Return of excess reimbursements (any advance beyond actual expenses must be returned)

For an S-Corp owner, an accountable plan can generate $5,000–$15,000 in additional deductible reimbursements per year that would otherwise be non-deductible.

Strategy 6: Manage Taxes Proactively Throughout the Year

All five strategies above require year-round attention to work properly. Entity elections must be made by March 15. Retirement plan contributions must be structured correctly. Equipment timing decisions must happen before December 31. None of these can be done retroactively after filing.

Proactive tax management means:

• Quarterly tax reviews: Check in with your advisor at least quarterly to review income trajectory, confirm estimated payments are correct, and flag any planning opportunities
• Year-end planning meeting: A dedicated session in October or November to finalize year-end moves before December 31
• Clean books: Current financials are required to make any of these strategies work — if you do not know your income as of October, you cannot plan intelligently
• Proactive advisor: An advisor who sends you a planning agenda before each meeting, not just a tax return after April 15

The difference between a reactive tax preparer and a proactive tax planner is typically measured in five-figure annual savings. For more on this distinction and how to evaluate your current advisor: Is Your CPA Actually Planning Your Taxes — or Just Filing Them?
