Open enrollment season arrives every year with a stack of benefits decisions to make, most of which are relatively straightforward. Then, you get deferred compensation.
Deferred comp eligibility tends to show up as a promotion milestone, a signal that you have arrived at a level of seniority that earns access to something most employees do not have. The instinct, almost universally, is to use it. Defer the income, reduce the tax bill this year, and put those savings to work. It sounds like a disciplined move. For many executives, it is one of the most expensive financial decisions they will ever make.
What Deferred Compensation Actually Does
A non-qualified deferred compensation plan allows you to elect before the year begins to redirect a portion of your salary or bonus into a separate account, deferring taxes until the funds are distributed. That distribution typically happens years or decades later, often at separation from the company.
The logic seems sound: defer income now, pay taxes later at a lower rate in retirement. The problem is the assumption embedded in that logic. The assumption that your tax rate will be lower when the distributions come out. For the executives we work with 5-10 years after they put their deferred comp on autopilot, there are plenty of stories where this turns out poorly.
The Bracket Math
Here is how the math can play out. An executive becomes eligible for deferred comp when household income is somewhere in the $275,000 to $400,000 range. For a married couple filing jointly, that places them in the 22 to 24% federal income tax bracket. Deferring income at that level means you are taking a tax deduction worth roughly 22 to 24 cents on the dollar.
The deferred funds accumulate. The executive continues to earn, promote, and grow. By the time those distributions are triggered, often at separation or retirement, when multiple years of deferred income are released simultaneously, income can spike into the 32, 35, or 37% bracket. In states like California and New York, add another 10-13%.
We had a client who had deferred millions of dollars when he was in the 22 to 24% bracket. By the time he left the company, all that money had been distributed. Between federal and state taxes, he was in a 50%+ bracket. He paid over half of it to the government.
One more critical point: the tax is on the principle and the growth. Every dollar of deferred income, and every dollar it earned inside the plan, is taxed as ordinary income on the way out.
Compare That to the Alternative
If that same executive had simply paid taxes on the income at 22 to 24%, invested the after-tax remainder in a non-retirement brokerage account, and paid the more favorable 15 to 20% long-term capital gains rate on growth over time, the math runs substantially in their favor compared to the deferred comp outcome.
This is not a knock on deferred comp as a tool. There are scenarios where it genuinely makes sense, particularly when an executive has a strong reason to believe their income will be significantly lower at the distribution date, or when the plan structure allows for meaningful flexibility in how distributions are timed. The decision deserves analysis far more than autopilot.
Three Questions to Ask Before You Check That Box
What tax bracket am I in today, and what do I reasonably expect my income to look like at distribution? If you expect to stay in a high bracket or higher, deferral is likely working against you.
Does my plan allow me to control when distributions occur, and how? Distribution flexibility varies significantly by plan design. Some allow installment elections; others force lump-sum payouts that can compress your tax liability into a single year.
Am I making this election with a full picture of my total compensation? Deferred comp does not live in isolation. It interacts with your LTI vesting schedule, your 401(k) strategy, your potential bonus payout, and your overall tax position for the year.
What We Do Instead
Before any open enrollment season, we sit down with our clients to review their total compensation picture and model the deferred comp decision in context. In many cases, the better move is to maximize after-tax 401(k) contributions, fund a backdoor Roth IRA, and keep the rest in a taxable account with a deliberate tax-management strategy built around it. (Consult your tax advisor for your own specific recommendations.)
The goal is not to minimize taxes this year. The goal is to minimize taxes over a lifetime.
If deferred comp election season is approaching for you, it is worth a conversation before you decide, not after. That window closes before the year begins and does not reopen.
