2026 Year-End Tax Planning: 10 Smart Moves toConsider Before December 31

November and December are valuable months to review your federal tax position before 2026 closes. Florida residents have no state individual income tax, but federal income taxes, investment gains, self-employment taxes and business reporting still require attention. The ten steps below are planning considerations, not one-size-fits-all instructions.

1. Project your 2026 income and tax liability

Review paystubs, business profit, investment activity and retirement distributions. Compare projected federal tax with withholding and estimated payments to identify a possible shortfall early enough to act.

2. Check withholding and estimated payments

An unexpected bonus, self-employment profit or capital gain can create an underpayment risk. Review IRS Form W-4 and the estimated-tax safe-harbor rules. The fourth federal estimated-tax installment for calendar-year 2026 generally falls in January 2027, but December planning still matters.

3. Evaluate retirement contributions

Review employer-sponsored plan deferrals and remaining room for 2026 contributions. The 2026 IRA contribution cap is generally $7,500, or $8,600 for those 50 and older, subject to compensation and eligibility rules. IRA contributions may be allowed after December 31 up to the applicable filing deadline, while payroll-deferral timing differs.

4. Review the new senior deduction

If you will be age 65 by year-end, review eligibility for the enhanced deduction of up to $6,000 per qualifying person. Higher modified adjusted gross income can reduce this deduction, making income timing worth discussing.

5. Check eligibility for new work-related deductions

Workers may qualify for deductions tied to qualified tips or overtime compensation, subject to occupation, reporting and income rules. Review your records and avoid assuming every tip or every dollar of overtime pay is deductible.

6. Review qualifying vehicle loan interest

If you financed a qualifying new U.S.-assembled personal vehicle after 2024, gather interest statements and vehicle details. Up to $10,000 of annual qualified interest may be deductible, subject to phaseouts.

7. Consider capital gains and losses

Review realized gains and potential losses in taxable investments. Tax-loss harvesting may offset certain gains, but the wash-sale rule and the broader investment strategy matter. Avoid executing trades purely for a deduction without considering economic risk.

8. Coordinate charitable gifts and records

If you plan to give to charity, confirm the organization is eligible and retain receipts and any acknowledgment required by law. The applicable deduction depends on itemizing and other rules; do not assume that every donation yields the same tax result.

9. Review small-business expenses and purchases

Business owners should reconcile books, review accounts receivable, substantiate deductible expenses and discuss major equipment purchases before acting. The timing and tax treatment of expenditures can differ under cash and accrual methods, depreciation rules and business-entity structures.

10. Schedule a tax projection before year-end

A tax projection can bring together wages, business income, investment transactions and the new federal provisions. For a married couple, self-employed taxpayer or household with retirement income, reviewing the whole picture is often more useful than focusing on a single deduction.

The bottom line

Good tax planning means understanding what applies to your actual income, filing status and records. Before December 31, gather your income estimates, last tax return, payroll statements, investment summaries and business records so your tax professional can identify the most useful next steps.
