Year-End Tax Planning Checklist: What to Bring to Your Strategy Meeting

You open your equity portal in November and see shares vesting, a final paycheck or severance terms in your inbox, or plans to relocate to Texas or Florida taking shape. April 15 is when you report what happened, but December 31 is when you decide how the year concludes. Walking into a year-end planning conversation without the right records leaves less time to consider decisions that must be made before the calendar turns.

A practical year end tax planning checklist keeps the conversation focused on decisions that remain open. For a high-earning tech professional, preparing for this meeting does not require memorizing the tax code. It simply means gathering core financial records so full-year income, equity positions, and potential withholding gaps can be reviewed before the year closes.

Why Missing Year-End Planning Costs Tech Executives

Waiting until spring to review compensation can turn planning questions into unexpected tax balances. In tech compensation, standard supplemental withholding on equity vests, bonuses, and severance may be less than the tax ultimately due. When vesting, severance, and ordinary salary stack up in a single calendar year, it is important to review whether withholding and estimated payments cover the year’s tax. For background, see RSU withholding shortfall.

Federal rules under the statutory recordkeeping requirements under federal tax law require taxpayers to maintain records sufficient to establish gross income, deductions, and credits. When income changes mid-year through a promotion, new grant, layoff, or relocation, the year’s tax picture changes too. Once the calendar year closes, opportunities for timing deductions or unwinding concentrated positions become fixed.

The Year End Tax Planning Checklist: What to Bring

To make a year-end strategy conversation productive, several categories of financial documents are helpful:

1. Most Recent Pay Stubs From All Employers

Pay statements show cumulative taxable wages, retirement plan contributions, and federal and state tax withheld to date. For tech professionals who changed employers during the calendar year, gathering pay stubs from each company is important. Statements from both employers help you assemble a picture of wages and withholding across the year.

2. Year-to-Date Equity Vest and Brokerage Statements

Restricted stock unit vest confirmations and brokerage reports can help you review vesting and share sales during the year. RSU shares are treated as wage income when they vest; see California RSU tax rate for more on that topic. Brokerage statements can also show any share sales completed during the year.

3. Severance and Departure Documentation

For individuals who experienced a corporate layoff, reviewing a severance agreement can help identify questions about departure pay. Severance is wage income subject to income tax, Social Security up to the wage base, and Medicare. Note whether it was paid in a single payment or continued payroll installments, and which tax year the payments fall in.

4. Prior-Year Federal and California Tax Returns

A copy of the prior-year tax return gives a strategist useful context for reviewing the year’s tax picture. Federal estimated tax safe harbor rules are one topic to discuss; the applicable threshold depends on the taxpayer’s circumstances.

5. Plans for Year-End Charitable Giving

For individuals planning charitable gifts, having recipient details and share valuations ready is helpful. Tech professionals holding appreciated shares often find that giving appreciated company stock to charity allows them to support philanthropic organizations while claiming a deduction based on fair market value for long-term shares.

6. Relocation Details and Workday Records

For individuals timing a move out of California to states such as Texas or Florida, residency dates and travel calendars can help frame questions about state tax treatment. Ask a strategist what information about your move and work locations is relevant to your equity compensation.

For general recordkeeping guidance, see IRS document gathering guidelines. When reviewing federal and state tax questions together, navigating state tax rules on capital gains may also be useful related reading.

Who This Checklist Applies To

This year-end checklist is designed for California tech executives, engineering directors, and high-income professionals earning $300,000 or more with equity compensation, concentrated stock positions, mid-year career changes, or multi-state residency questions.

Taxpayers with straightforward wage income and no equity compensation generally have standard payroll withholding that covers their annual liabilities.

What a Tax Strategist Looks at in Your Meeting

A year-end tax planning review focuses on how salary, vesting events, and career changes interact before December 31. Bringing together these details gives the strategist context for discussing the year’s tax picture and the decisions still open.

Questions Worth Bringing to Your Strategist

• Based on year-to-date equity vests and salary, will current withholding meet the federal safe harbor to prevent an underpayment penalty?
• How will severance pay or unvested equity forfeiture impact marginal tax brackets for the remainder of the year?
• If planning a move out of California, how will the state source equity that vests after the relocation?
• Would donating appreciated company stock before December 31 provide a greater deduction than giving cash?

This is the kind of situation a Roadmap tax strategist reviews with clients before December 31.

FAQ

What should I bring to a year-end tax planning meeting?

As a general example, someone preparing for a year-end tax planning meeting could bring recent pay stubs, a summary of equity vesting and sales, a prior-year tax return, any severance information, and notes about planned charitable gifts.

What is the difference between tax planning and tax preparation?

Tax preparation reports historical financial data on annual returns, while tax planning evaluates financial decisions before December 31 to manage tax liability.

Why does RSU withholding often fall short for tech earners?

Supplemental withholding rates applied to vesting shares often trail the higher combined federal and California marginal rates that apply to high-income earners.

Does California still tax my equity after I move?

California tax treatment of equity compensation after a move can depend on the circumstances, including where work was performed. Ask a strategist which information about your move and work history is relevant to your situation.
