NQDC Deferral Calculator

Non-qualified deferred compensation (NQDC) plans let senior tech employees at Google, Meta, Apple, and other large public companies defer salary and bonus income before it's taxed. The question is whether deferral actually wins after all the trade-offs — lower tax rate at distribution, tax-deferred compounding, and employer bankruptcy risk. This calculator runs both paths side by side so you can see the real numbers.

Amount to defer ($) Salary and/or bonus amount you're considering deferring in a single year. Most NQDC plans allow deferring up to 100% of bonus and a large portion of salary.

Current combined marginal tax rate (%) Federal + state income tax on your next dollar. A FAANG senior engineer in California: 37% federal + 13.3% CA = 50.3%. In WA/TX with no state income tax: ~37%.

Expected tax rate at distribution (%) Your expected combined federal + state rate when you receive distributions (typically in retirement or after leaving a high-cost state). Conservative estimate: 28–35%. Optimistic: 20–25%.

Long-term capital gains rate (%) Your federal LTCG rate + NIIT if applicable. High earners: 20% + 3.8% NIIT = 23.8%. Mid-range: 15%. CA note: CA taxes LTCG as ordinary income — if you'll still be in CA at sale, use your full CA rate instead of the LTCG rate.

Expected annual investment return (%) Real expected return on the invested funds. 7% is a common long-run estimate for a diversified equity portfolio. NQDC plan investments are typically mutual funds mirroring your 401(k) options.

Years until distribution How many years before distributions start. Under § 409A, you must elect the distribution schedule before year-end of the year preceding the deferral year. Most tech plans offer 5-, 10-, 15-, or 20-year scheduled distributions.

How the math works

Two dollars of the same gross income take different paths:

NQDC path: $D deferred → grows at r for n years → taxed as ordinary income at distribution rate T_dist
After-tax value = D × (1 + r)ⁿ × (1 − T_dist)

Taxable path: $D received → pay income tax at T_now → invest D × (1 − T_now) → grows at r for n years → pay LTCG tax on gains only at sale
After-tax value = D × (1 − T_now) × [(1 + r)ⁿ × (1 − T_ltcg) + T_ltcg]

NQDC wins in two ways: it compounds on a larger pre-tax base, and it converts ordinary income from a high-rate year into ordinary income at a (presumably) lower-rate year. Even if tax rates at distribution are the same as today, the tax-deferral compounding alone gives NQDC an edge over a taxable account — though not over a Roth account.

The three risks that can flip the math

1. Employer bankruptcy risk

NQDC funds are not segregated assets. They sit on the company's balance sheet, and you are an unsecured general creditor. If your employer files for bankruptcy before your distribution date, you could receive cents on the dollar — or nothing. This risk is low at a healthy company like Google or Apple, but it's real: Nortel, Enron, and WorldCom had large NQDC obligations that were substantially impaired in bankruptcy. For concentration-sensitive employees, consider whether the same company already dominates your RSU and 401(k) holdings.

2. Rate risk (distributions arrive at a high-income year)

The model assumes you receive distributions during a low-income period. But scheduled NQDC distributions are inflexible — § 409A prohibits acceleration (with narrow exceptions). If your distribution schedule runs right as you do significant Roth conversions, sell a house, or have other high-income events, the distribution can land in a higher bracket than you anticipated. Build the distribution schedule around your projected income for those specific years before you make the irrevocable election.

3. Liquidity lock-in

Once elected, the distribution timing is locked. You cannot take an early withdrawal to fund a home purchase, start a business, or manage a financial emergency without triggering § 409A penalties (20% excise tax + interest). The money is gone from your liquid balance sheet until the scheduled distribution date. Make sure your taxable account and emergency reserves are fully funded before maximizing NQDC.

When NQDC almost always makes sense

You're in California now, plan to leave before distributions. The 13.3% CA rate makes the current marginal rate ~50%. A post-move distribution at 24–30% federal (no CA) is a 20+ percentage-point rate arbitrage.
You're deferring bonus income in a peak equity-vest year. A year where RSUs, ESPP, and bonus all land simultaneously pushes you deep into the 37% bracket. Deferring the bonus prevents bracket stacking.
You've already maxed 401(k), Mega Backdoor Roth, and HSA. NQDC is the next best tax-deferral vehicle for compensation that can't go into a qualified plan.
The company is in strong financial health with no near-term distress signals. For FAANG-tier companies with fortress balance sheets, employer bankruptcy risk is remote enough to accept.

When to think twice

Your state doesn't tax NQDC distributions. Some states (PA, IL, and a few others) do not tax NQDC distributions. If you're already in a 0-income-tax state like Texas or Washington, the current-vs-future rate gap shrinks or disappears.
You expect a later high-income event. If you're planning a business sale, large real estate transaction, or large Roth conversion in the distribution window, adding NQDC distributions can compress everything into a single high-rate year.
The company's financial picture is uncertain. Startups and mid-size companies with NQDC plans are unusual and warrant extra scrutiny. The unsecured creditor risk matters more when the company isn't AAA-rated.
You haven't funded your Roth options first. A Roth 401(k) / Mega Backdoor Roth grows completely tax-free. NQDC distributions are taxable. If you have Roth space unused, fill it before NQDC.

§ 409A election mechanics (the window you must not miss)

For salary deferrals: the election must be made by December 31 of the year before the compensation is earned. For bonus deferrals: the election must typically be made by June 30 of the performance year (for bonuses based on that year's performance), or by December 31 of the prior year for time-based bonuses. Miss the window and you cannot defer that year's compensation — there is no retroactive cure.¹

Distribution elections must also be made upfront. You choose from the distribution options your plan offers (specific date, specific number of years, separation from service, etc.) at election time. A subsequent change is allowed only under very narrow § 409A conditions and must push the distribution at least five additional years into the future.¹

Need help deciding how much to defer?

The right NQDC deferral amount integrates with your RSU vest schedule, 401(k) elections, Mega Backdoor Roth contributions, and state residency plans — and must be set before the year-end deadline. A fee-only advisor who works with senior tech employees can model the full picture across all accounts and build a multi-year deferral strategy.
