Reading your first benefits enrollment form

A new job comes with a stack of benefits choices and a short deadline. Here’s what each option means, and which ones are hard to change later.

Mind the deadline

New employees usually get a limited window to enroll, often around 30 days from the start date. If you miss it, you may have to wait until the next open enrollment period, usually once a year, unless you have a qualifying life event such as marriage, a new baby or losing other coverage.

The choices you make now are mostly locked in for the plan year, so it’s worth an hour of your time.

Health insurance

You’ll usually choose between several plans. Compare them on:

Premium: what comes out of each paycheck.
Deductible, copays and coinsurance: what you pay when you use care.
Out-of-pocket maximum: the most you could pay in a year for covered, in-network care.
Network: whether your doctors are included.

A quick way to compare: add a year of premiums to the out-of-pocket maximum. That’s your worst case for each plan. If the terms are new to you, see Health insurance terms, explained.

HSA or FSA?

These accounts let you pay for medical costs with money that isn’t taxed.

HSA (Health Savings Account): only available with a qualifying high-deductible health plan. The money is yours: it rolls over every year and stays with you if you leave the job. Some employers add money to it.
FSA (Flexible Spending Account): available with many plans. It’s mostly use it or lose it: money left at the end of the year may be forfeited, though some plans allow a small carryover or a grace period. Only put in what you’re confident you’ll spend.

There may also be a dependent care FSA for childcare costs, which works separately.

Retirement plan

If there’s a 401(k), 403(b) or similar plan, find two things:

The match. For example, “50% of what you contribute, up to 6% of pay.” Contribute at least enough to get the full match. It’s part of your pay.
The vesting schedule. This says how long you must stay before the employer’s contributions are fully yours. Your own contributions are always yours.

You may choose between traditional (pre-tax now, taxed when withdrawn) and Roth (taxed now, generally tax-free when withdrawn later). If you’re unsure, splitting between them is a reasonable start.

The rest of the form

Life insurance: many employers provide a basic amount for free. Extra coverage costs money and matters most if someone depends on your income.
Disability insurance: replaces part of your pay if you can’t work because of illness or injury. It’s often more likely to be needed than life insurance, and worth taking if it’s cheap or free.
Dental and vision: usually small premiums, and worth comparing to what you’d pay without them.
Beneficiaries: name who receives your retirement account and life insurance if you die. This overrides your will for those accounts, so keep it up to date.
