Your Tax Return as an Executive: What It Reveals and Why It Matters

As an executive, your compensation grows more complex and so too does your tax return. Equity awards vest, long-term incentives pay out, deferred compensation is distributed, and income may be recognized years after it was earned—even across multiple states. Without coordination, this complexity can result in unexpected tax liabilities and missed planning opportunities. When reviewed strategically, however, a tax return becomes a powerful tool for aligning compensation decisions with long-term financial goals.

A thoughtful review of an executive’s tax return can help you:

One thing becomes clear in conversations with senior leaders: the tax return filed each April is rarely just about taxes. It is instead a reflection of how compensation, incentives, and long-term planning intersect to help bring them closer to reaching their financial goals.

As executives move upward in their careers and performance goals are met, compensation often becomes more layered, complex and rewarding over time. Equity awards begin to vest, deferred compensation may start to be paid—meaning a tax return reflects years of progress and smart decisions made over time, not just the last twelve months.

Seen properly, your tax return becomes less a formality and more a strategic snapshot that tells a story.

An executive compensation package often has many components, which also have different tax treatments. We take a look at the most common components below.

While each component may be understandable on its own. The challenge—and opportunity—comes from understanding how they interact in a comprehensive financial plan. Let's take a look at a few common pitfalls.

A few pitfalls you can watch out for in reviewing your tax return are:

Underwithholding of Taxes
As mentioned above, employers withhold taxes on bonuses at a flat 22% up to $1 million. For an executive in the highest marginal tax bracket, this can result in an unexpected tax liability as well as underpayment penalties owed to the IRS. To mitigate this risk, you can work with your advisor and CPA to request a tax projection to ensure you are withholding the optimal amount, and also accounting for state taxes, especially in high tax states such as New York or California.

Alternative Minimum Tax (AMT)
ISOs are the most common trigger. When exercised, the spread between the strike price and market value increases AMT income— if the shares aren’t sold within the year. The result can be a tax liability based on “phantom income,” making tax planning essential, especially if your income is over the exemption phase out threshold of $500,000 for single filers and $1,000,000 for married filing jointly ² .

State and Local Taxes (SALT)
Executives working across multiple states often face additional filing requirements, and may overlook the SALT deduction limits. Under current law, the SALT deduction for tax year 2026 is capped at $40,400 for most taxpayers with phase downs beginning at modified adjusted gross income of $505,000, and a floor of $10,000 for taxpayers who are fully phased down, limiting relief for high earners in high-tax states ³ .

A tax return isn’t only a record of what happened. It’s a preview of what’s coming.

A careful review can reveal several strategies to help optimize your tax planning as follows:

When tax planning is integrated into your financial plan, it strategically connects compensation decisions to long-term outcomes, and can help ease the burden of unpleasant surprises during tax season.
