Deferred Compensation Plan Employer Match: Restoration, Excess and Discretionary Credits

A deferred compensation plan employer match is a credit your company adds to an executive's NQDC account, most often to restore the 401(k) match that IRS limits take away. It is worth offering when you want the plan to reward saving and retention, and you are prepared to explain its vesting and its value clearly enough that your eligible executives actually see it.

Employer money is common in private-employer NQDC plans, but the survey figures vary with who was asked. NAPA reported in February 2025 that PSCA's 2024 NQDC survey found about 80% of employers contribute to their plans and that half of those make a restoration match. A 2025 survey by Principal, a plan provider, found 43% of sponsors offer employer contributions, from a sample of 83 sponsors that Principal itself calls small and directional. The two surveys cover different years and different groups of sponsors, and samples like these tend to skew toward larger sponsors and providers' clients. Either way, a match is a mainstream design choice, not an outlier.

This guide covers private-employer top-hat plans under Section 409A, not governmental 457(b) plans. Your plan document governs how any credit works, so involve counsel, your recordkeeper and your advisers before adding or changing one.

Types of employer contributions in NQDC plans

Employer credits come in a handful of forms. Many plans use more than one.

The last row is usually treated as a separate plan. See SERP vs. NQDC vs. restoration plan for how they compare.

How a restoration match works

Executives lose 401(k) match in two ways. The 401(a)(17) limit caps the pay the qualified plan can count, and NQDC deferrals may reduce the pay the 401(k) formula recognizes. A restoration match recalculates the match as if neither limit applied and credits the difference to the NQDC account.

Here is an illustrative example with assumed numbers. Say your 401(k) matches 100% of the first 4% of pay, and an executive earns $500,000 in salary in 2026.

If NQDC deferrals also reduce the pay your 401(k) formula recognizes, the 401(k) match falls further and the restoration credit grows to fill the gap. An excess compensation match would credit 4% of the $140,000 above the limit, which is the same $5,600 here, but it does not restore match lost to NQDC deferrals. The IRS is expected to publish 2027 limits in November, so check the figures before each plan year.

Plans maintained solely to restore benefits lost to qualified-plan limits also have their own exception from state source taxation under 4 U.S.C. §114. Whether your plan qualifies is a question for counsel. The state tax and moving guide explains why it matters to retirees.

Vesting schedules and FICA timing

Vesting is what turns a credit into a retention tool. In the 2024 Newport/PLANSPONSOR survey, company contributions most often vested 100% after three years or after five years (36% each). Newport, part of Ascensus, is an NQDC provider. Shorter or graded schedules are easier to explain. Longer cliffs hold people longer but feel less like "real" money to them. The executive retention guide covers how to balance the two.

FICA is due when credits vest, not when they are paid

Under the FICA special timing rule in Treas. Reg. §31.3121(v)(2)-1, NQDC amounts are generally taken into account for Social Security and Medicare tax at the later of when the services are performed or when the amount is no longer subject to a substantial risk of forfeiture. For employer credits with a vesting schedule, that usually means the vesting date.

Plan for three consequences:

• Cliff vesting concentrates the tax. Several years of credits can become FICA wages in one year. For executives whose wages already exceed the Social Security wage base, usually only Medicare tax applies, but the withholding still has to come from somewhere.
• Coordinate with payroll. Your recordkeeper and payroll provider need the vesting dates and amounts so tax is taken on time. If an amount is not properly taken into account when it vests, FICA can apply later at payout, including on the earnings.
• Tell participants. Executives are often surprised to see FICA on money they cannot yet touch. Once taken into account, later earnings and payouts are generally not subject to FICA again.

What a match costs and when it is recognized

The cash cost of a match is the credits themselves, plus any earnings credited on them, minus forfeitures from unvested balances. Add administration and the cost of any informal funding, such as a rabbi trust or corporate-owned life insurance.

Here is illustrative arithmetic with stated assumptions, not data. Suppose 20 executives participate and the average restoration credit is $6,000 a year. That is $120,000 of credits a year before earnings and forfeitures. If two of those executives leave before vesting in a given year, their unvested credits are forfeited and reduce the net cost.

Two timing points to confirm with your tax and accounting advisers:

• Tax deduction. Under 26 U.S.C. §404(a)(5), an employer generally deducts nonqualified deferred compensation in the year the employee includes it in income, which is usually the payout year, not the year it is credited.
• Book expense. For financial reporting, the liability is generally accrued as it is earned, often over the vesting period. Your auditors will set the method.

The result is a mismatch: the company books expense well before it gets the deduction. Informal funding can help manage the cash and earnings effects, but it does not change when the deduction is available.

How your employees should value employer credits

An employer credit is not worth the same as a cash bonus of the same size, and your eligible executives will value it more accurately if you explain why. The main adjustments:

• Vesting. Unvested credits can be forfeited. An executive who may leave within the vesting period should discount them.
• Employer credit risk. Credits are unsecured promises. In a bankruptcy, participants stand behind secured creditors, and a rabbi trust does not change that. See NQDC risks and rabbi trusts.
• Taxes at payout. Credits and their earnings are taxed as ordinary income when paid, at the tax rate and in the state that applies then. See how deferred compensation is taxed.
• Deemed investment growth. Credits track the plan's notional investment options, so their value moves with those choices and their fees.
• Payout schedule. The election the executive makes, lump sum or installments, affects the after-tax value.

Where a credit is tied to deferring, such as a restoration match that applies only if the executive defers, a decision not to participate also means giving up the credit. That makes the credit one of the clearest reasons to model the election rather than skip it.

Does a match raise participation, and how should you communicate it?

The surveys cited here do not isolate how much a match lifts participation, so treat claims that it does with care. What the data does show is that understanding is the bigger problem. In the 2026 Newport/PLANSPONSOR survey, lack of understanding was the most cited participation barrier (46%). Principal's 2025 survey found 53% of participating employees said the plan matters when deciding whether to stay, which suggests the plan's value has to be visible to do its retention work.

To make the money you spend on a match visible:

• Show the credit in dollars for a typical eligible employee, using the same arithmetic as the example above.
• State the vesting schedule and the FICA timing in plain language.
• Show the match alongside the other trade-offs: tax now versus later, payout schedule and employer credit risk.
• Repeat it in the enrollment window, when people are deciding.

A private modeling tool can do this for each employee. When you license NQDC Calculator, your employer credits, vesting and 401(k) formula are configured with you as starting values. Each employee then sees the credit and its vesting inside their own projection, with federal and state tax for both paths and a break-even employer risk. You never see their inputs or results, and the tool never recommends an election. For more ways to raise engagement, see how to increase NQDC plan participation.

Frequently asked questions

What share of NQDC plans include employer contributions?

It depends on the survey. NAPA reported that PSCA's 2024 survey found about 80% of employers contribute, with half of those making a restoration match. Principal's 2025 survey of 83 sponsors found 43%, a figure Principal calls directional. The samples differ, so use the range rather than a single number.

How does a restoration match differ from an excess compensation match?

An excess compensation match applies the 401(k) formula only to pay above the 401(a)(17) limit, $360,000 in 2026. A restoration match recalculates the full match as if no limits applied, which can also replace match lost because NQDC deferrals reduced the pay the 401(k) counts. Restoration is broader and usually costs more.

What vesting schedules are typical for employer credits?

In the 2024 Newport/PLANSPONSOR survey, company contributions most often vested 100% after three years or after five years, at 36% each. Restoration matches are sometimes vested on the same schedule as the 401(k) match. Longer schedules hold people longer but are harder to communicate.

When is an NQDC employer match deductible?

An employer generally deducts NQDC under IRC §404(a)(5) in the year the employee includes it in income, usually the payout year. For financial reporting, the expense is generally accrued as it is earned. Confirm both with your tax and accounting advisers.

Do employer credits trigger Social Security and Medicare tax?

Yes, generally when they vest. Under the FICA special timing rule, credits are taken into account at the later of when the services are performed or when they vest, so cliff vesting can concentrate the tax in one year. Earnings credited after that are generally not subject to FICA again.
