NQDC Distribution Calculator (2026)

Once you have a non-qualified deferred compensation balance, the question shifts from how much to defer to how to get the money out efficiently. Taking a $2M NQDC balance as a lump sum can pile it entirely into the 37% federal bracket. Spreading it over 5 or 10 years may let a significant portion clear at 24% or 32% instead — a material difference on a seven-figure balance.

This calculator models three distribution schedules side-by-side: lump sum, 5-year installments, and 10-year installments. Enter your projected balance and retirement income to see total taxes and after-tax proceeds for each option.

Why the distribution schedule matters so much

NQDC distributions are taxed as ordinary income in the year received — no capital gains treatment, no step-up in basis, no Roth conversion option. Every dollar lands on top of your other income and is taxed at your marginal rate. For a C-suite executive with a $3M NQDC balance and $100K in other retirement income:

The bracket differential alone can be worth several hundred thousand dollars on a $3M balance. Add state tax (California taxes NQDC distributions as ordinary income at up to 13.3%), and the gap widens further.

The four 409A distribution triggers — and how they interact with your election

Under IRC §409A, you elect both a trigger and a schedule at the time you defer. The six permissible triggers are:

• Separation from service — the most common. You leave, distributions begin. For specified employees (key employees of public companies), there is a mandatory 6-month delay before the first payment.
• Specified date or fixed schedule — example: "beginning January 1, 2032, regardless of employment status."
• Change in control — an acquisition or merger meeting the §409A 50%/30% voting power or asset tests.
• Disability — substantially unable to engage in gainful activity.
• Death — distributions to beneficiaries.
• Unforeseeable emergency — limited hardship withdrawals; strict rules apply.

Most executives use "separation from service" or a fixed date. The schedule (lump sum vs. installments) is part of the election — and installment elections are treated as a series of separate payments for 409A purposes, which makes re-deferral elections more flexible in some plans.

What this calculator does not model

• Balance growth during the distribution period. This calculator assumes level payments on the projected balance. In practice, undistributed portions continue to grow at the plan's reference rate during the payout period, which increases effective returns of longer schedules. Consider this a conservative underestimate of installment plan value.
• Social Security taxation. Up to 85% of SS benefits are included in taxable income when combined income exceeds thresholds. NQDC distributions push many retirees into full inclusion. Enter your full SS amount in the "other income" field; the brackets will capture the correct marginal rate.
• IRMAA Medicare surcharges. NQDC distributions increase MAGI, which is used to set Part B and Part D premiums with a two-year lookback. A $1.2M lump sum in one year triggers the top IRMAA tier ($429.60/mo Part B surcharge per person) for the following two years — roughly $10,300/person in additional premiums. Installments can be sized to stay below IRMAA tier jumps.
• Employer credit risk. NQDC balances are unsecured obligations. Every year you defer distribution, you extend your exposure to the employer's solvency. See our NQDC creditor risk guide.
• State source-income rules. Some states (notably California) can tax NQDC distributions based on where services were performed during the deferral period — not just where you live at distribution. This is a separate issue from the state rate you enter. See our equity and state tax guide.
• Tax law changes. Distribution schedules often span 5-15 years. Tax rates in 2032 are speculative. OBBBA (2025) permanently extended current-law brackets, but future legislation can change them.

The IRMAA optimization

For executives who will be on Medicare during distribution years, IRMAA surcharges add a parallel tax at certain income inflection points. The 2026 Part B IRMAA tiers (per person) are:

A 10-year installment schedule sized to keep annual MAGI below $266,000 (MFJ) avoids the upper IRMAA tiers entirely. A lump sum that spikes income to $2M+ locks you into the maximum surcharge for two years after the distribution year. For a married couple, that's up to $11,566/year in added Medicare premiums — a real cost the bracket analysis doesn't capture.
