You can't control the election. You can control your deferred comp election, and it's probably due before December 31.
If your company offers a nonqualified deferred compensation (NQDC) plan, you're about to make one of the biggest tax decisions of your year, often in a five-minute benefits portal session. Most executives decide on a feeling: "I'll be in a lower bracket later." That feeling might be right. But you don't have to guess. The decision comes down to four numbers and one break-even rate, and you can test all of them before the window closes.
The election that's quietly due
An NQDC plan lets you push part of your salary or bonus into the future. You don't pay income tax on it now. The money grows inside the plan, and you pay tax when it's paid out, years from now.
The catch is timing. Under the tax rules for these plans, the election to defer next year's pay generally has to be made before next year starts, so by December 31. Many plans set an earlier deadline, often in November or early December. Some bonus elections follow a different calendar. Check your plan's enrollment materials for the actual date. Don't assume you have until New Year's Eve.
Two more things are usually locked in at the same time: how much you defer and when and how it's paid out (a lump sum or installments, at a set date or at separation). Changing the payout later is possible in some plans, but the rules make it slow and restrictive. Treat this as a decision you make once.
The four numbers
Here's everything the math needs:
- Your tax rate on this pay if you take it now. Federal plus state, at the margin. This is the tax you avoid today by deferring.
- Your tax rate when the plan pays it out. Your best realistic estimate of your combined rate in the payout years.
- What the money earns inside the plan. Based on the investment options your plan actually offers.
- What it would earn outside the plan, after tax. If you took the cash, paid the tax, and invested what was left in a taxable account.
That's it. Everything else is commentary until these four are on paper.
A worked hypothetical
Say you defer $100,000 for 10 years. Your combined tax rate is 45% now, and you expect 35% at payout. The money grows at 6% a year inside the plan and 5% a year after tax outside it.
Defer it. $100,000 grows at 6% for 10 years to about $179,100. You pay 35% tax at payout and keep about $116,400.
Take it now. You pay 45% today, which leaves $55,000. That grows at 5% after tax for 10 years to about $89,600.
Deferring comes out roughly $26,800 ahead. But that's not the number I'd anchor on.
The break-even rate is the number that matters
Ask a different question: how high would your payout tax rate have to be for taking the money now to win?
In this hypothetical, the deferred balance is about $179,100 before tax. Taking it now finishes at about $89,600. The two paths tie when the payout tax leaves you with $89,600, or about 50% of the balance. The break-even payout rate is about 50%.
That's the whole decision in one number. If you're at 45% today and expect 35% later, you have about 15 points of cushion. Your payout rate could land 10 points higher than you plan and deferring would still win.
Here's why it's useful. Nobody knows what tax rates will be in 10 years. You don't have to. You only have to judge whether your rate is likely to climb past the break-even, and that's a much easier call.
Notice what moves the break-even:
- Growth inside vs. outside the plan. If the money earned 6% in both places, the break-even would drop to 45%, exactly your rate today. The plan's tax-deferred growth is what buys you the extra cushion.
- A weak investment menu. If the plan only earned 4% while your taxable account earned 5% after tax, the break-even would fall to about 39.5%. That's still above 35%, but the cushion shrinks from 15 points to under 5.
- Time. The longer the deferral, the more the growth gap compounds in either direction.
Beyond the math
The four numbers tell you whether deferral pays. These four questions tell you whether it fits:
- Where will you live at payout? Moving from a high-tax state to a no-tax state can change your payout rate a lot. Federal law limits how a former state can tax certain NQDC payments, especially installments spread over 10 years or more. Ask your CPA how your plan's payout schedule is treated.
- Lump sum or installments? A lump sum can push a big payout into the top bracket in a single year. Installments spread it out. Remember, this is usually chosen now.
- What's on the investment menu? Look at the options and costs, and how the balance fits the rest of your portfolio. It's part of your allocation, not a separate bucket.
- How much already depends on this employer? An NQDC balance is an unsecured promise from your company. If the company runs into trouble, you're a general creditor. Add that to your salary, your bonus, your RSUs, and your options. If one employer already drives most of your net worth, the break-even math isn't the only risk to weigh.
The decision rule
Here's how I'd put it in a plan:
Defer when the break-even payout rate is comfortably above your realistic payout rate, and your exposure to your employer is already sized. Otherwise, take it now.
To run it:
- Find your plan's election deadline and payout options. Put the date on your calendar.
- Write down your four numbers. Use your actual plan menu for growth inside the plan.
- Calculate the break-even payout rate.
- Compare it with your realistic payout rate. Look for a real cushion, not a coin flip.
- Add up everything tied to your employer: pay, equity, and the existing deferred balance. Decide how much more you're willing to stack on top.
- Pick a payout schedule on purpose, with your CPA, before you submit.
Rules over feelings.
