Tax Planning for Executives in 2026: Year-End Moves for Salary, Bonuses, Stock Compensation and Deferred Pay

Why executives overpay on taxes, and what to do before December 31

Tax planning for executives has a timing problem. Salary, bonuses and equity pay all arrive in a pattern that withholding was not built to handle, and most of the useful decisions have to be made before December 31. At J&E Advisory Group, we see the same surprise every spring: a large balance due from a year that looked fully withheld.

The numbers explain why. For 2026, the 37% federal rate applies to taxable income above $640,600 for a single filer and above $768,700 for married couples filing jointly. On top of that, wages above $200,000 ($250,000 for joint filers) carry a 0.9% Additional Medicare Tax, and investment income can add a 3.8% Net Investment Income Tax. An executive with a bonus and a vesting equity grant can cross all of these lines in one year.

This guide covers the moves that matter most in the weeks that remain: workplace retirement plans, bonus withholding, stock compensation, deferred compensation, charitable giving and the surtaxes. Every figure below is for 2026 and comes from official sources listed at the end.

Strategy 1: Max out your 401(k) and executive retirement contributions (2026 limits)

Retirement contributions are the simplest lever, and they must be done through payroll by year-end. Here are the 2026 limits:

• 401(k), 403(b) and governmental 457(b) elective deferrals: $24,500.
• Catch-up contribution at age 50 or older: an additional $8,000.
• Higher catch-up at ages 60 to 63: $11,250 instead of $8,000.
• Total limit for all contributions to a defined contribution plan (employee plus employer): $72,000.
• IRA contribution limit: $7,500.

Check your payroll election now. If you want to reach the limit by December 31, your remaining paychecks may need a higher percentage than you set in January.

One change affects older executives. Starting in 2026, if your Social Security wages from your employer in the prior year were above $150,000, your catch-up contributions must be made as Roth contributions. That means no upfront deduction. We covered this in more detail in our post on the new 401(k) catch-up rule: https://www.jeadvisorygroup.com/blogs/new-401-k-catch-up-rule-could-raise-taxes-for-older-high-earning-workers

Also note the plan compensation limit of $360,000 for 2026. Employer contributions and some plan formulas cannot count pay above it.

Strategy 2: Bonus tax withholding and year-end estimated tax payments

Employers generally withhold federal tax on bonuses as supplemental wages at a flat 22%. The rate rises to 37% only on supplemental wages above $1 million in a calendar year. For an executive in the 35% or 37% bracket, 22% withholding on a large bonus leaves a gap that shows up in April.

Social Security tax also stops once wages pass the 2026 wage base of $184,500, which can make late-year paychecks look larger. That is not extra income to spend. It is often the point where an under-withholding problem is easiest to miss.

Practical steps before year-end:

• Run a projection of your full-year income, including bonus and equity income, and compare it with total withholding to date.
• Ask HR to increase withholding on your final paychecks. Withholding is treated as paid evenly through the year, which makes it more flexible than a late estimated payment.
• If you also have side income, board fees or investment income, review estimated tax payments. Our guide to avoiding estimated tax penalties explains the rules: https://www.jeadvisorygroup.com/blogs/estimated-taxes-are-a-pain-here-s-how-to-avoid-costly-penalties

Strategy 3: Stock options, RSUs and equity compensation tax planning

Equity pay is where executives most often face a large, unplanned bill. The tax depends on the type of award.

Nonstatutory stock options are generally taxed when you exercise. You report the value of the stock received, less what you paid, as income in the year of exercise. Incentive stock options (ISOs) are different. The IRS says you generally do not include anything in income when you receive or exercise an ISO, but the exercise may trigger the alternative minimum tax (AMT). If you do not meet the special holding period rules, the sale is taxed as ordinary income.

The AMT is a parallel tax calculation. For 2026, the exemption is $90,100 for unmarried taxpayers, phasing out above $500,000 of income, and $140,200 for joint filers, phasing out above $1,000,000. An executive exercising a large ISO block can owe AMT even with no cash sale.

Questions to settle before year-end:

• Which awards vest or can be exercised before December 31, and what is the expected income from each?
• Would exercising ISOs in a lower-income year, or in smaller pieces over several years, reduce AMT exposure?
• Is your employer’s withholding on vested shares enough, given that the flat supplemental rate may be below your actual bracket?
• Is a large share of your net worth concentrated in one company stock? Tax is one input, and diversification is another.

Because equity rules are detailed, we model the numbers before recommending a path.

Strategy 4: Nonqualified deferred compensation and Section 409A

Many executives can defer part of their salary or bonus into a nonqualified deferred compensation plan. The IRS describes this type of plan as an arrangement between an employer and employee to pay compensation in the future. Deferral can move income to a later, possibly lower-income year.

The risk is Section 409A. If a plan fails to meet its requirements, the IRS says deferred amounts can become currently taxable. The failure can also add a 20% additional income tax and a separate premium interest tax, and these fall on the employee, not the employer.

Elections generally have to be made on time, and changing the timing of payments later is restricted. Before electing a deferral for next year, confirm the payout schedule fits your plans for retirement, a move, or a job change. Also remember that deferred balances are generally an unsecured promise from your employer.

Strategy 5: Charitable giving for high-income executives

Giving can still reduce taxable income, but the rules shifted in 2026. Non-itemizers can now deduct up to $1,000 of cash gifts ($2,000 if filing jointly), which matters little to most executives. For itemizers, IRS course materials note that charitable gifts must now exceed 0.5% of the contribution base before a deduction is allowed. The IRS also notes that the tax benefit of itemized deductions is limited for taxpayers in the 37% bracket.

The practical result is that large gifts in one year can be more efficient than small gifts every year. Executives with appreciated stock often look at donating shares instead of cash, and bunching several years of gifts into one year. These strategies have limits and paperwork requirements, so confirm them with an advisor before you act.

Strategy 6: The surtaxes and the thresholds that trigger them

Two taxes catch executives by surprise:

• Additional Medicare Tax: 0.9% on Medicare wages above $250,000 for married filing jointly, $125,000 for married filing separately and $200,000 for everyone else. Your employer must start withholding it once your wages pass $200,000, whatever your filing status.
• Net Investment Income Tax: 3.8% on net investment income when income is above $250,000 for joint filers, $125,000 for married filing separately and $200,000 for single filers and heads of household. These thresholds are set by statute and are not adjusted for inflation.

Married couples where both spouses earn well should check whether combined withholding is enough, because each employer withholds based on its own payroll.

Common mistakes executives make at year-end:

• Waiting until January to look at the full-year picture, when the main decisions are already closed.
• Assuming withholding on a bonus or vested shares covers the tax.
• Exercising ISOs without modeling AMT.
• Electing deferred compensation without checking the payout schedule.
• Giving cash when appreciated shares would be more efficient.
• Ignoring state tax. Rules vary widely, and a move or remote work arrangement can change which state taxes your pay.
• Skipping foreign account reporting. If you hold accounts, equity or property abroad, FBAR and other reporting may apply even when the income is already taxed in another country.

What to do next: a year-end checklist

1. Project your full-year income, including bonus and equity, and compare it with withholding.

2. Confirm your 401(k) deferral will reach the 2026 limit by your last paycheck.

3. List every equity award that vests or can be exercised this year.

4. Review any deferred compensation election for next year.

5. Decide on charitable gifts and whether to give cash or stock.

6. Gather foreign account and income details, if any.

7. Book a planning meeting before mid-December, so there is time to act.

Frequently asked questions about tax planning for executives

How can executives reduce their taxes legally?

The most reliable levers are maximizing workplace retirement plans, timing equity exercises, using deferred compensation where it fits and planning charitable gifts. Each has rules and trade-offs, so results depend on your facts.

What is the 2026 401(k) limit for executives?

The 2026 employee deferral limit is $24,500, with an extra $8,000 catch-up at age 50 or older and $11,250 at ages 60 to 63. The total limit for employee and employer contributions to a defined contribution plan is $72,000.

Why is tax withheld on my bonus so low?

Employers generally withhold a flat 22% on supplemental wages, rising to 37% only on amounts above $1 million in a year. If your actual bracket is 35% or 37%, the difference can come due when you file.

Do I owe tax when I exercise incentive stock options?

Generally you do not include ISO exercise in regular income, but the exercise may trigger the alternative minimum tax. Selling without meeting the holding period rules makes the sale ordinary income.

What happens if my deferred compensation plan fails Section 409A?

The IRS says deferred amounts can become taxable in the current year, with an additional 20% tax and premium interest, assessed against the employee. Confirm payout timing and elections before you sign.

Do I owe the Additional Medicare Tax?

It applies at 0.9% to Medicare wages above $250,000 for joint filers and $200,000 for most other filers. Employers must begin withholding once wages pass $200,000.

What if I also have foreign accounts or income?

You may have extra reporting duties, such as FBAR, and foreign taxes may be creditable. J&E Advisory Group helps executives and international taxpayers coordinate U.S. returns with foreign filings, so nothing is missed.

What should I do if I already owe tax or got an IRS notice?

Do not ignore it. Deadlines to respond are short, and penalty relief may be available in some cases. Our IRS tax resolution team can review the notice and your options.

When should I start year-end tax planning?

Start in November. Payroll changes, option exercises and deferral elections take time, and most must be completed before December 31.

Executives and other high earners need year-round planning, because bonuses, equity and deferred pay create tax decisions that cannot be fixed after December 31. J&E Advisory Group, based in Miami, serves high-income earners across the U.S. and international taxpayers worldwide, from tax planning and FBAR reporting to foreign national tax preparation, complex international tax matters and IRS tax resolution, in English and Spanish.
