What Should You Generally Check About Vesting Before Accepting a New Job Offer?

A new job offer lands with a better salary and a shiny benefits summary, but tucked into the retirement plan section is a vesting schedule that means walking away from the current employer resets the ownership clock on any future matching contributions back to zero.

In a nutshell

Before accepting a new offer, it’s generally worth understanding the new employer’s vesting schedule, whether it uses cliff or graded vesting, how many years of service it requires, and whether the current employer’s plan has any features, like accelerated vesting, that could be forfeited by leaving early. None of this changes salary negotiations directly, but it affects the real value of a retirement benefit being offered, which is easy to overlook next to a more visible number like base pay.

Details worth reviewing in the new plan

What’s being left behind at the current job

Reviewing a soon-to-be-former employer’s plan matters just as much as reviewing the new one. Checking exactly how much of the current employer match is already vested, and how close a person might be to a vesting milestone, can sometimes make a real difference in whether it’s worth timing a departure around a specific date. This is especially relevant since people commonly don’t realize their match wasn’t fully vested until after they’ve already left and the unvested portion has been forfeited back to the plan.

Rolling over an old account

Once a departure happens, the vested portion of an old retirement account generally comes along, typically through a rollover into a new plan or an individual retirement account, while any unvested portion stays behind with the previous employer permanently. Understanding this distinction ahead of time helps clarify that the vesting decision and the rollover decision, while related, are actually two separate questions.

Why vesting details rarely come up during interviews

Vesting schedules are usually documented in a summary plan description, a document most candidates never ask to see before accepting an offer, since salary, title, and start date dominate the conversation. Because vesting schedules vary significantly from one employer to another, and because the specific rules aren’t always summarized clearly in a benefits overview handed out during onboarding, requesting the actual plan document directly is usually the most reliable way to get a full answer.

Worth remembering

Vesting details rarely change whether an offer is worth accepting, but understanding them ahead of time avoids an unpleasant surprise down the line, whether that’s discovering a forfeited match at the old job or realizing the new job’s vesting clock is longer than expected before that match becomes fully owned.
