LGBTQ+ Employee Benefits: Open Enrollment Guide

How marriage vs. domestic partnership changes your health insurance taxes, FSA and HSA access, FMLA rights, and 401(k) protections. Not financial or legal advice — your specific situation requires qualified counsel.

Employee benefits are where the legal difference between marriage and domestic partnership has the most immediate dollar impact. For same-sex couples who are legally married, employer benefits work essentially the same as for opposite-sex married couples. For couples who are not legally married — domestic partnerships, civil unions in states where those remain distinct from marriage, or simply cohabiting — the tax and legal treatment is materially different, and often expensive. This guide explains what changes and what doesn't.

Health insurance: the imputed income tax on domestic partner coverage

When you add a legally married same-sex spouse to your employer health plan, the employer's premium contribution on your spouse's behalf is excluded from your taxable income under IRC §106 — the same treatment as any married couple. You pay no income tax or FICA on that employer benefit.

When you add a domestic partner, the tax treatment is different. Unless your domestic partner qualifies as your tax dependent (see the next section), the employer's premium contribution for your partner is treated as imputed income — added to your W-2 as taxable compensation. You pay ordinary income tax and FICA on the full fair market value of that employer contribution each paycheck.

The imputed income figure should appear on your W-2 in Box 12 with Code C (taxable cost of group-term life) or reflected in Box 1 wages, depending on how your employer reports it. If you're not sure whether you're being taxed on imputed income for DP health coverage, ask your HR or payroll department for a copy of your employer's domestic partner benefits policy. Use our Marriage vs. Domestic Partnership Calculator to model the annual cost for your specific income and premium amounts.

Note: some states — including California, New York, and Oregon — exempt registered domestic partners or same-sex domestic partners from state-level imputed income, even when federal imputed income applies. Check your state's specific rules; the state tax savings can partially offset the federal hit.

FSA and HSA: the domestic partner dependency trap

This is the most commonly misunderstood employee-benefit rule affecting LGBTQ+ households who are not legally married.

Healthcare FSA (Flexible Spending Account)

You may use healthcare FSA funds for medical expenses of your legal dependents under IRC §152. A domestic partner qualifies as a dependent only if they meet the qualifying relative test:

• Their gross income for the year is below $5,300 (2026 threshold)¹
• You provided more than half of their total financial support during the year
• They are not claimed as a dependent by anyone else
• They are a U.S. citizen, national, or resident, or resident of Canada or Mexico

If your domestic partner earns more than $5,300 in 2026 — which applies to virtually every working couple — they do not qualify as your tax dependent. That means you cannot use your FSA funds to pay their medical bills. If you do and your employer audits, you'll owe tax and penalties on the improper distribution.

For legally married same-sex spouses: spouses are always qualifying dependents for FSA purposes regardless of income. You can freely use your FSA for their medical expenses. The 2026 Healthcare FSA contribution limit is $3,400 per employee; if both spouses work and each has an FSA, the household can shelter up to $6,800 per year.²

Health Savings Account (HSA)

The same dependency rule applies to HSAs. Under IRS rules, HSA-qualified medical expenses are those paid for you, your spouse, or your dependents. A domestic partner who does not meet the qualifying relative test is not your dependent, so their medical expenses are not HSA-qualified.

In practice: if you have an HSA and your partner is not your legal dependent, you should not pay their medical bills from your HSA. Doing so makes those distributions taxable plus subject to a 20% penalty (if under age 65).

The 2026 HSA contribution limits are $4,400 for self-only coverage and $8,750 for family coverage (where the family includes a qualified dependent).³ To contribute at the family rate, your HDHP must actually cover qualifying family members — a domestic partner who is not your tax dependent does not make you eligible for family-level HSA contributions.

FMLA and parental leave

Federal FMLA for same-sex spouses

The U.S. Department of Labor amended the FMLA definition of "spouse" in 2015 using a place of celebration rule: if your marriage was valid where it was entered into, federal FMLA covers it regardless of where you currently live. Same-sex spouses are fully covered by federal FMLA on the same terms as opposite-sex married couples.⁴

Covered FMLA leave for same-sex spouses includes: leave to care for a seriously ill spouse, leave for the birth, adoption, or placement of a child (bonding leave), and military family leave when a spouse is called to active duty.

Federal FMLA for domestic partners

Federal FMLA does not extend to unmarried domestic partners for the purposes of spousal-care leave. You cannot take federal FMLA leave to care for a seriously ill domestic partner. There is a narrow exception: if you stand in loco parentis to your partner's child (you provide day-to-day care or financial support), you may take FMLA bonding leave for that child even without a legal adoption.

State law can be more protective. California, New Jersey, New York, Connecticut, Oregon, Washington, and several other states have passed family leave laws that cover care for domestic partners. If you live in one of these states, check whether your state's leave law provides DP coverage that supplements federal FMLA.

Parental leave for LGBTQ+ families

Most large employers have parental leave policies (distinct from FMLA) that go beyond the federal floor. Review your specific plan document carefully. Key things to look for:

• Does the policy cover surrogacy? Policies often cover "birth parent" and "non-birth parent" leave separately. Intended parents in surrogacy arrangements should confirm their legal standing as parents and whether the policy treats them as birth parents or adoptive parents — the distinction can affect the leave duration offered.
• Does the policy cover second-parent adoption? Second-parent adoption finalizes your legal parental status; most parental leave policies trigger on adoption finalization. Confirm the clock and length.
• Does the policy cover both partners? Most policies at large employers now allow both partners to take parental leave, regardless of gender or which partner gave birth or carried. Read the policy for "primary caregiver" vs. "secondary caregiver" designations that may limit one partner's leave.
• Qualifying life event for open enrollment: Birth, adoption, and placement of a child are all qualifying life events (QLEs). You have a 30–60 day window (confirm with your employer) to change your health insurance elections. This is typically when you add your newborn or newly adopted child to your health plan.

401(k) and retirement plan beneficiary rights

ERISA §205: qualified joint and survivor annuity for married spouses

For pension plans (defined-benefit plans), ERISA §205 requires a default form of payment called a Qualified Joint and Survivor Annuity (QJSA): at least 50% of the pension continues to a surviving legal spouse after the participant's death. To elect a different form of payment — lump sum, single-life annuity — the participant must get the spouse's written, notarized consent.

This automatic protection applies to legally married same-sex spouses exactly as it does to opposite-sex spouses. A domestic partner has no equivalent statutory right; they can only receive a survivor benefit if the participant specifically named them as beneficiary in the plan documents and elected the appropriate payment option.

401(k) beneficiary designations

For 401(k) and similar defined-contribution plans, the default beneficiary is the legal spouse (required under ERISA for married participants). A married same-sex spouse is automatically the default primary beneficiary unless they sign a written waiver.

For an unmarried domestic partner, there is no default statutory protection. If you want your domestic partner to receive your 401(k) at death, you must actively name them as beneficiary on the plan's beneficiary designation form. Many people set this form when they first enroll and never update it — meaning an ex-partner, parent, or sibling may still be named. Review your beneficiary designations as a routine part of any major life change.

Also relevant: a domestic partner who is your beneficiary for a 401(k) does not qualify for a spousal rollover. They must take the inherited 401(k) as a non-spouse beneficiary and distribute it under the 10-year rule (IRC §401(a)(9)(H)). A legally married same-sex spouse, by contrast, can roll the inherited account into their own IRA and defer distributions indefinitely. The after-tax difference over a lifetime can be substantial. See our LGBTQ+ Retirement Planning Guide for a full comparison.

Group life insurance

Employer-provided group life insurance does not restrict who you name as beneficiary — you can designate a domestic partner, a chosen-family member, or any other individual without their being your legal spouse or dependent. This is one area where marital status does not limit your options.

What does differ: for large estates, life insurance proceeds passing to an unmarried partner are included in the survivor's taxable estate and are not protected by the unlimited marital deduction (IRC §2056), which applies only to legally married spouses. For most households this is not a near-term issue, but for couples with substantial combined assets, the estate-tax treatment of survivor benefits is one component of the broader "when does marriage change the financial picture" analysis.

When you leave a job, check whether your group life policy is portable or convertible. Group coverage ends when employment ends; if you have a health condition that would affect underwriting, converting to an individual policy before separation avoids a medical exam requirement.

Open enrollment strategy for two-income LGBTQ+ households

Open enrollment is your annual window to optimize benefits across both partners' employers. A few principles for LGBTQ+ households:

If you are legally married: Treat benefits coordination the same way any dual-income married couple would. Compare plans at each employer on premium, network, deductibles, and HSA/FSA eligibility. The main LGBTQ+-specific consideration is making sure beneficiary forms, coverage elections, and payroll records reflect your legal name and marital status accurately — particularly if you changed names after marriage.

If you are not legally married:

• Model the imputed-income tax cost before adding your partner to your plan. If your employer's premium is high and your marginal rate is also high, the tax cost may exceed the premium savings from family coverage. Use the Marriage vs. DP Calculator or ask an advisor to model this.
• Each partner having their own HDHP and contributing to their own HSA is often more tax-efficient than one partner having family coverage with the imputed-income hit and the other's medical expenses being ineligible for the HSA.
• Keep your FSA/HSA funds strictly for your own eligible expenses. Do not commingle.
• Name your partner explicitly on all beneficiary designation forms each open enrollment period or after any life event.

Getting married mid-year is a qualifying life event that allows you to change benefit elections outside of open enrollment — typically within 30–60 days of the marriage date. Use this window to: (1) add your spouse to your health plan without imputed income, (2) drop duplicate DP coverage at the other employer if applicable, (3) update HSA contributions if your coverage type changes, and (4) update all beneficiary designation forms to reflect your new legal status.

Questions to ask HR

When reviewing benefits, these questions surface LGBTQ+-specific details that general benefits guides skip:

1. Does the health plan recognize domestic partners for coverage, and how is the employer premium contribution taxed? Ask for the plan's domestic partner benefits policy in writing, not just a verbal answer.
2. What is the fair market value (FMV) of employer-provided DP health coverage? This is the number that determines your imputed-income W-2 addition. Some employers report it; others calculate it per their plan actuary.
3. Does the parental leave policy cover surrogacy and second-parent adoption, and does it apply to both partners? Confirm the duration for birth parents, non-birth parents, and adoptive parents separately.
4. Does the company's FMLA policy extend to domestic partners for spousal-care leave? Some employers voluntarily extend FMLA-equivalent coverage beyond the federal floor. Others do not. The answer matters if your partner has a serious illness.
5. Can I see my current 401(k) and life insurance beneficiary designations on file? You can request this at any time; open enrollment is a natural moment to review and update.

When to involve a financial advisor

Benefits decisions for LGBTQ+ households involve interacting tax, ERISA, and estate-planning rules that general financial planning tools do not model well. The scenarios that most benefit from professional help:

• You are weighing the financial tradeoffs of getting legally married vs. remaining domestic partners — the benefits piece is one component of a broader analysis that includes federal and state taxes, Social Security, estate planning, and existing asset ownership.
• You are expecting a major family-formation event (surrogacy, adoption, birth) and want to optimize the interaction between parental leave, adoption tax credits, employer adoption assistance (IRC §137), and HSA contributions.
• One partner has a pension with a QJSA election and the survivor benefit choice involves non-trivial tradeoffs between the default QJSA and a lump-sum or single-life-annuity option.
• You have been together for years as domestic partners and are transitioning to legal marriage — the mid-year open enrollment window is narrow, and an advisor can help you sequence changes (health, HSA, beneficiaries, estate documents) without gaps.
