Year-End Tax Planning Checklist

Year-end tax planning is a forward-looking review of financial activity, anticipated income, tax payments, and other relevant changes before the tax year closes. The purpose is not to guarantee a specific tax result, but to identify areas that may deserve attention while planning opportunities or payment adjustments can still be evaluated.

Review Changes in Income

Consider whether wages, self-employment income, business profits, investment income, retirement distributions, or other income sources changed materially during the year. Significant changes may affect projected federal or California tax obligations.

Review Estimated Tax Payments and Withholding

Compare estimated tax payments and withholding with current-year income expectations. A prior-year payment pattern may not reflect a year involving business growth, a bonus, investment activity, or another significant financial change.

Organize Business and Financial Records

Business owners should review whether bank and credit card accounts are reconciled, transactions are consistently categorized, and significant purchases or unusual transactions have supporting documentation. Organized records support more reliable tax preparation and planning discussions.

Consider Retirement-Related Planning

Depending on the taxpayer's circumstances, retirement plan contributions and other retirement-related decisions may be relevant to year-end planning. Contribution limits, eligibility, plan rules, and timing requirements should be reviewed before taking action.

Review Major Transactions or Financial Events

Business acquisitions, sales, real estate activity, equity compensation, investment transactions, changes in residency, and other significant events may create tax considerations. These issues are generally easier to evaluate when discussed before a transaction is completed or before filing season begins.

Prepare for Upcoming Filing Obligations

Identify the records, tax forms, business financial information, and other documents likely to be needed for tax preparation. Early organization can reduce delays and help identify missing information before filing deadlines approach.

Key Takeaway

Year-end planning is most useful when the review reflects the taxpayer's actual income, payments, business activity, and anticipated changes. The appropriate planning steps depend on the specific facts and applicable tax rules.
