Retirement
Intel SERPLUS: a complete guide
SERPLUS, the Sheltered Employee Retirement Plan Plus, is Intel's nonqualified deferred compensation plan. It lets eligible higher-grade employees push part of their salary and bonus into future years, beyond what the 401(k) allows, with an Intel match on pay above the IRS compensation limit. It is also an unsecured promise from Intel, with elections that lock a year ahead and payout rules fixed by federal tax law. This guide works from the plan document Intel files with the SEC and its proxy statements.
What SERPLUS is
A 401(k) is a qualified plan: the money sits in a trust creditors cannot touch, and in exchange the IRS caps what goes in. A nonqualified plan is the opposite trade: no contribution cap, but the money legally remains Intel's until paid, and you are taxed only on receipt. Intel's plan document, filed as an exhibit to its 10-Q and amended in 2021 and 2022, describes a plan established in 1991 and restated effective January 1, 2020 to add matching contributions. The fiscal 2025 10-K reports the balance at $3.2 billion, a liability on Intel's balance sheet: Intel's debt to participants, not participants' property.
Three accounts live inside it: an Earnings Deferral Account (your salary and bonus deferrals), a Company Contribution Account (the match since 2020 and, for longer-tenured employees, pre-2020 discretionary contributions) and notional investment earnings on both.
Who is eligible
Intel sets eligibility each year by job grade, since the plan is limited to "a select group of management or highly compensated employees." The restated plan listed grades 10 to 20, 25 to 28, 46 to 49 and 85 to 90 for 2020; the First Amendment set grades 10 to 20, 25 to 28 and 85 to 90 for 2021; the Second Amendment set grades 10 to 21, 25 to 28 and 85 to 90 for 2022. In practice, double-digit grades. Eligibility in one year does not guarantee the next, and union-covered employees, interns, contractors and staff off the US payroll are excluded.
New hires who qualify become eligible on the "New Hire Eligibility Date," the January 1 or July 1 after they qualify, with an election due by the preceding June 30 or December 31. Everyone else elects by December 31 of the prior year.
Deferral elections and when they lock
You make two separate elections each fall for the following year:
- Salary deferral: a percentage of base pay up to a ceiling Intel sets each year; the 2026 proxy says participants may defer "up to 60% of their salary."
- Bonus deferral: 1% to 75% of your Employee Bonus in 1% increments. Employee Bonus means the Annual Performance Bonus (APB) and commissions; the Quarterly Profit Bonus (QPB) and equity gains cannot be deferred.
Once the plan year starts the election is irrevocable: "No Participant shall be permitted to increase or decrease the rate of deferral or stop the deferral." That is federal law, not Intel policy. Section 409A requires the election "not later than the close of the preceding taxable year," and a plan that let participants change course mid-year would expose everyone to immediate taxation plus a 20% additional tax. Decide in the fall with a realistic view of next year's cash needs; you cannot undo it in March.
The Intel match inside SERPLUS
Since 2020 Intel has matched SERPLUS deferrals on pay above the 401(k) compensation limit. The plan defines "Excess Earnings" as total eligible earnings minus the earnings counted under the 401(k) plan (which stop at the IRS limit, $360,000 for 2026), with QPB excluded. The match "shall equal five percent of the Eligible Employee's Excess Earnings for the Plan Year," capped at the amount you actually deferred. You must make deferrals during the year and be eligible for the 401(k) true-up match. The match is credited after year-end and is 100% vested, as are your deferrals; the 2026 proxy confirms "matching contributions are 100% vested."
Example: eligible earnings of $450,000 in 2026, none of it QPB, means Excess Earnings of $90,000 and a potential match of $4,500, provided you deferred at least $4,500. This mirrors the 5% match in the 401(k), which Intel cut from 7% on January 1, 2025 (see the Intel benefits guide); the SERPLUS formula was not changed by the 2021 or 2022 amendments.
Pre-2020 company contributions, the old discretionary retirement contribution on excess pay, vest 20% a year from two years of service to 100% at six, or fully at age 60, death or disability; unvested amounts are forfeited at termination.
Distribution elections
You choose how each year's deferrals are paid when you make the deferral election, and that choice is also locked under 409A: a later change must be made 12 months in advance and push the payment out at least five years. The options:
| Option | Terms in the plan document |
|---|---|
| Lump sum at separation | Paid as soon as practicable after your termination date, or in the following year |
| Annual installments | Five or ten annual payments beginning the year after termination |
| In-service distribution | A fixed date at least three calendar years after the start of the plan year being deferred; not available for pre-2020 company contributions |
| Default if no election | Pre-2020 amounts: lump sum soon after termination. 2020 and later company contributions: lump sum in March of the year after termination |
| Small balances | $5,000 or less is paid as a lump sum after termination regardless of election |
| Death | Since 2023, a lump sum in the year after death regardless of other elections |
Because Intel is publicly traded, "specified employees" (broadly, top officers) face a mandatory six-month delay on separation payments under 409A(a)(2)(B)(i), which the plan builds in. Installments are what make SERPLUS a tax tool rather than a savings account.
The unsecured-creditor risk
The plan is explicit: your right to a distribution "shall be an unsecured claim against the general assets of the Company." Intel may fund a grantor trust informally, but its assets "shall remain subject to claims of creditors of the Company." If Intel could not pay its debts, SERPLUS participants would stand in line with other unsecured creditors; a 401(k) balance would not be in that line. The plan also lets Intel offset payments to recover amounts you owe it.
This is why "how much should I defer?" has no single answer: the tax saving is worth having only if Intel pays. Treat a nonqualified balance as a concentrated, unsecured bond issued by your employer, keep it within an amount you could lose without derailing retirement, and favor shorter payouts if you are uneasy about the issuer. Through the 2024 to 2025 restructuring the plan paid as designed; the balance fell from $3.3 billion to $3.2 billion between year-ends as departing participants were paid.
How SERPLUS fits with the 401(k) limits
The two plans stack. In 2026 you can defer $24,500 into the 401(k) ($32,500 with the catch-up at 50 and older), the Intel match applies to pay up to $360,000, and all contributions combined cannot exceed $72,000. SERPLUS sits above those lines: no dollar cap, a match on the pay the 401(k) ignores, and no effect on the 401(k) limits. SERPLUS deferrals also do not reduce the pay on which your 401(k) match is calculated, because the plan counts deferred amounts as earnings.
A sensible order: capture the full 401(k) match and reach the $24,500 limit; fill after-tax 401(k) space and convert it to Roth, since that money is protected in trust (the mega-backdoor Roth calculator shows the room); defer into SERPLUS at least enough to collect the 5% match; defer more only when the tax arbitrage is clear and you accept the credit risk. RSU income cannot be deferred, but it is why many participants sit in the top bracket; see the RSU tax guide.
Tax strategy: high-bracket years into low-bracket years
Deferred pay is taxed when received, at that year's rates. The 2026 federal brackets (IRS, Rev. Proc. 2025-32) reach 32% at $201,775 of taxable income for a single filer ($403,550 joint), 35% at $256,225 ($512,450) and 37% above $640,600 ($768,700). An engineer with $450,000 of salary and bonus plus RSU vests pays 35% or 37% on the top slice; deferred and paid over ten years in retirement against perhaps $120,000 of other income, that slice is taxed at 22% or 24%, a spread of 11 to 15 points before state tax and before growth on the pre-tax balance.
Three refinements:
- Choose installments for retirement, lump sums for near-term goals. A lump sum at separation can land in your highest-income year, alongside severance and a final RSU vest, wiping out the benefit. Ten annual installments spread the income across low-bracket years.
- State tax follows you, with one federal rule in your favor. Intel's largest US sites are in Oregon, Arizona, California, Texas and New Mexico, states with very different income taxes. Under 4 U.S.C. 114, deferred compensation paid in substantially equal periodic payments over at least ten years (or for life) is taxed only by the state where you live when paid. A ten-year election made in Oregon and received in Texas is taxed by neither state; lump sums and shorter schedules get no such protection.
- Mind the stacking. Deferring too much bonus can leave you short of cash for tax on RSU vests, which are withheld at only 22% federal. Run the RSU tax calculator before setting the percentage.
If SERPLUS is worthwhile for you, the rest of your plan needs the same attention; see financial planning for high earners.
What happens at separation
Your termination date is your "Separation from Service" and starts the clock on the payout election on file for each year's deferrals. Your own deferrals and the post-2020 match are never forfeited; pre-2020 company contributions pay out only to the extent vested. A lump-sum default adds the full balance to the income of the year you leave or the year after, so an employee laid off in a restructuring year can face a tax spike exactly when cash flow is weakest; the Intel severance guide sequences severance, final vests and SERPLUS payouts. Retirement follows the same rules.
Common mistakes
- Defaulting into a lump sum. The default pays company contributions in March of the year after you leave, often a retiree's worst year to receive it.
- Deferring before the 401(k) is full. The 401(k) is protected in trust and has the same 5% match; fill it first.
- Forgetting the election is irrevocable. A 50% bonus deferral set in November cannot be undone when a down payment comes up in April.
- Ignoring the ten-year state-tax rule. Five installments instead of ten can cost the full source-state tax on the whole balance.
- Missing the QPB exclusion. The Quarterly Profit Bonus is neither deferrable nor counted in Excess Earnings; plan the match around APB and salary.
Bottom line. SERPLUS is a real tax tool for Intel employees in the 32% to 37% brackets: unlimited deferral of salary and APB, a 5% match on pay above $360,000, and installment elections that can move income into low-bracket, low-tax-state retirement years. Its costs are irrevocability and unsecured-creditor status. Max the 401(k) first, defer at least enough to collect the match, elect ten-year installments for retirement money, and never defer cash you might need before the payout date.
Intel amends SERPLUS through its Management Retirement Plans Administrative Committee, and eligibility grades and the salary deferral ceiling are reset each year. Confirm the current plan year's terms in Intel's benefits portal and the Section 409A rules on irs.gov before making an election.
