Year-End Tax Planning

Strategies to reduce your tax bill before the year ends.

Why Year-End Planning Matters

The end of your tax year is your last opportunity to impact that year's tax result. While year-round planning is ideal, year-end actions can significantly reduce what you owe.

Many tax-planning strategies have timing components—accelerating expenses into the current year or deferring income to the next. With careful planning in December, you can often save thousands in taxes with minimal disruption to your business.

Start your year-end planning early—ideally in October or November. This gives time to implement strategies rather than rushing in the final days. Good planning also helps avoid the stress of last-minute decisions.

Accelerate Deductions

Moving deductible expenses from next year into the current year reduces this year's taxable income. The earlier you can claim the deduction, the sooner you get the tax benefit.

**Pay Year-End Expenses Early:** Send invoices or make payments due in January by December 31. This includes rent, utilities, insurance premiums, and professional services. If you have bills coming due early next year, consider paying them now.

**Prepay Expenses:** Many expenses can be prepaid and deducted in the current year. This includes insurance premiums, subscriptions, and membership dues. The IRS allows prepayments that create economic benefit in the current year.

**Order Equipment and Supplies:** If you need equipment, furniture, or significant supplies, order and receive them by year-end to claim the deduction. Under Section 179, you may be able to deduct the full cost immediately rather than depreciating over time.

Section 179 Deduction

Section 179 allows immediate deduction of up to $1,160,000 of qualifying equipment purchases in 2024 (subject to phaseout). This is a powerful year-end planning tool for businesses investing in equipment, vehicles, or furniture.

Revenue and Expense Timing

Strategic timing of revenue and expenses can significantly affect annual tax liability. Cash versus accrual accounting creates different timing opportunities. Cash Basis Planning: Cash-basis businesses can control taxable income through payment timing. Accelerating collections in December accelerates taxable income. Deferring payments to January defers the deduction. This flexibility is valuable but limited by business reality—you cannot collect from unwilling customers or pay expenses not yet due. Accrual Basis Considerations: Accrual-basis businesses have less flexibility but still have timing options. Revenue recognition policies, allowance estimates, and expense accrual methods all affect timing. These methods should be consistent year-over-year to avoid auditor scrutiny but can be optimized within acceptable accounting standards. Year-End Cuts: Certain expenses must be accrued at year-end to be deductible in the current year. This includes accrued but unpaid salaries, bonuses, and vacation pay. Establishing proper accruals requires estimating amounts due and ensuring economic liability exists at year-end.

Defer Income Strategically

Delaying income to the next tax year can reduce your current tax bracket and potentially provide better tax rates. This is especially valuable if you expect next year to be lower-income or if tax rates might change.

**Invoice Timing:** If you control when you invoice customers, consider whether sending invoices in December (taxable this year) or January (taxable next year) better serves your planning. For cash-basis businesses, receiving payment determines taxable timing.

**Hold Off on Year-End Bonuses:** If you pay annual bonuses, consider whether paying them in early January instead of December shifts the deduction to the following year. This requires weighing the timing benefit against employee satisfaction.

Be careful not to defer income merely to avoid taxes if doing so creates cash flow problems or harms customer relationships. The tax benefit must be balanced against business needs.

Maximize Retirement Contributions

Retirement contributions are one of the best year-end tax-planning tools—they reduce income, build wealth, and provide tax benefits.

**SEP-IRA:** If you're self-employed or have a small number of employees, SEP-IRA contributions for the year can be made until the tax filing deadline (including extensions). However, making contributions by year-end ensures you don't forget.

**Solo 401(k):** Contributions have both employee deferral and employer match components. For 2024, you can defer up to $23,000 as employee contributions, plus up to 25% of compensation as employer contributions (capped at $69,000). Don't leave money on the table.

**Simple IRA:** Employer contributions must be made by year-end to count for that year. If you have a SIMPLE IRA, ensure employer matches and profit-sharing are funded by December 31.

Advanced Year-End Planning Techniques

Beyond basic timing strategies, sophisticated year-end planning involves evaluating the overall tax position and implementing advanced techniques. Charitable Contributions: Charitable giving provides deductions at fair market value for appreciated property, avoiding capital gains tax while receiving deduction. C-corporations can deduct up to 10% of taxable income. Individual shareholders can deduct up to 60% of adjusted gross income. Planned giving can maximize benefit while meeting philanthropic goals. NOL Utilization: Net operating losses can offset profits in other years. Understanding NOL generation, carryforward, and utilization rules enables planning. Losses can offset built-in gains when S-corporation elections terminate. Loss utilization requires careful tracking and planning. Accounting Method Changes: Changing accounting methods can provide retroactive deductions for items previously deducted improperly. Revenue recognition method changes, inventory costing changes, and depreciation method changes may be available. These changes require IRS approval and involve transition rules that require careful planning.

Review Your Tax Situation

Year-end is the time to project your annual tax liability and see what planning opportunities remain. Waiting until after year-end limits your options.

Estimate your taxable income and compare to tax brackets. If you're near bracket thresholds, targeted actions can keep you in lower brackets. Conversely, if you're well into a higher bracket, maximizing deductions has less incremental benefit.

Consider your state tax situation as well. Many states conform to federal treatment but some don't—understanding your state's rules ensures accurate planning.

Quarterly Tax Planning Integration

Year-end planning should integrate with quarterly estimated tax requirements. Changes in estimated tax liability should be reflected in quarterly payments to avoid underpayment penalties. Analyzing year-end planning impact on quarterly requirements ensures compliance while managing cash flow. Coordination between book and tax timing affects quarterly calculations.
