# Timing Is Everything: Catch-Up Contributions vs. Deferred Compensation

If you're a highly compensated employee age 50 or older, you've probably noticed that the last stretch of your career is when savings get both more important and more complicated. You have more income to work with, fewer years to let it grow, and a growing list of rules about where that money can go.

Two tools come up again and again in planning conversations: **401(k) catch-up contributions** and **nonqualified deferred compensation (NQDC) plans**. Both let you set aside more for retirement. But they have different implications on your immediate and future tax liabilities.

**Part 1: The 401(k) catch-up clock**

Catch-up contributions let participants aged 50 and older contribute above the standard 401(k) limit. Under SECURE 2.0, the age bands now look like this for 2026:

| Age in 2026 | 401(k) Limit | Catch-Up Limit | Total Possible |
| --- | --- | --- | --- |
| 50 – 59 | $24,500 | $8,000 | $32,500 |
| 60 – 63 | $24,500 | $11,250\* | $35,750 |
| 64 or older | $24,500 | $8,000 | $32,500 |

*\*if plan allows*

Starting in 2026, if your prior-year FICA wages from your employer (W-2 Box 3) were above $150,000, your catch-up contributions generally must be made on a Roth, after-tax basis. If your plan doesn't offer a Roth option, you may not be able to make catch-up contributions at all until the plan adds one. Check your W-2 and ask your HR team where your plan stands. Most plans need to be amended by the end of 2026.

**Part 2: The NQDC option**

NQDC plans are offered by some employers to a select group of executives and highly compensated employees. They aren't subject to the 401(k) contribution limits, which is why they appeal to people who are already maxing out their qualified plan. They also run on stricter timing rules, driven largely by Section 409A of the tax code, and are subject to insolvency risk.

**Questions to consider**

Every situation is different, but here are a few questions for retirement savers to consider:

1. Does my 401(k) offer a Roth option, and am I subject to the Roth catch-up rule?
2. Am I on track to use my full catch-up this year without hitting the limit early and losing the match?
3. Does my employer offer an NQDC plan, and when is the election deadline for next year?
4. If I defer, when do I want the money paid, and does that match my retirement plans?
5. How comfortable am I with my employer's long-term financial strength?

**Understanding the mechanics**

Listed below are several distinctions retirement savers may want to understand when thinking holistically about their current financial state and retirement savings:

1. **Tax-rate arbitrage**. A Roth contribution is taxed now, at whatever marginal rate applies to the highest slice of your income. For a high earner in peak earning years, that can be the top federal bracket, plus state income tax. NQDC defers that income, so the tax is paid at distribution. If you expect your retirement income to land in a lower bracket, you pay less in total tax on the same dollars. If your rate is the same in both periods, the two approaches come out roughly equal, and the Roth only wins if your future rate is higher.
   
   Important: Roth balances are protected from your employer’s creditors, whereas NQDC plans are generally an unsecured promise.
2. **Capacity**. NQDC has no statutory contribution cap, so someone who has already maxed out the 401(k), including catch-up, can shelter more income than a Roth option allows. A larger pre-tax amount means a larger reduction in current taxable income.
3. **Control over when income lands**. NQDC participants choose payout dates in advance. Staggering distributions over several years after retirement can keep each year’s income in lower brackets than a lump sum would. Someone planning to relocate to a state with no income tax may also benefit from receiving the money after the move, and federal law restricts how states tax certain long-term retirement payouts. That is worth confirming with a tax adviser.
   
   Roth 401(k) balances are no longer subject to lifetime required minimum distributions, and Roth money is a hedge if tax rates rise. A Roth can be rolled, moved, and accessed under familiar rules, whereas NQDC is bound by Section 409A’s election and payout restrictions and cannot be rolled into an IRA.
4. **Proximity to retirement**. For workers over 50, the gap between peak earnings and retirement income is often short and predictable. That makes the “lower bracket later” assumption easier to defend than it would be for someone in their 30s with decades of career growth ahead.
5. **Income-based thresholds**. Lowering adjusted gross income now can help with thresholds tied to it, such as certain deductions, credits, and surtaxes. The value depends on where you sit relative to them.

**The bottom line**: a highly compensated worker age 50 or older may lean toward NQDC when they expect a meaningfully lower tax rate in retirement, have already used their qualified-plan room, and trust their employer’s long-term financial strength. They lean toward a Roth when they expect equal or higher rates, want creditor-proof and flexible money, or want tax-free growth. Many retirement savers split between the two for diversification.
