You meet your health insurance deductible once per plan year. For most people, that means once every 12 months, with the counter resetting to zero at the start of the next year. Every dollar you’ve paid toward your deductible disappears, and you start over.
The exact reset date depends on your type of coverage, and a few important details determine how this plays out in practice.
When Your Deductible Resets
All individual and marketplace health plans operate on a calendar year. No matter when you purchased your plan, the deductible resets on January 1. Even if you bought coverage on December 1, you’d face a brand-new deductible just one month later on January 1.
Employer-sponsored group plans can be different. Many employers choose a plan year that doesn’t start in January. A company might set its plan year to begin June 1 or October 1, for example. In those cases, your deductible resets on the plan’s renewal date rather than January 1. Your benefits summary or HR department will list the specific dates of your plan year.
Medicare Part B also resets annually on January 1. The 2025 Part B deductible is $257, up from $240 in 2024.
What “Meeting” the Deductible Actually Means
Your deductible is the amount you pay out of pocket for covered medical services before your insurance starts sharing costs. If your deductible is $1,500, you pay the first $1,500 of eligible medical bills yourself each plan year. After that, your plan typically begins covering a percentage of costs (this is where copays and coinsurance kick in).
Not every medical expense counts toward your deductible, though. Monthly premiums never count. And charges for services your plan doesn’t cover won’t count either. Only the amounts you pay for in-network, covered services typically apply.
One significant exception: most health plans are required to cover preventive services at no cost to you, even before you’ve met your deductible. This includes immunizations, many screening tests, and annual wellness visits. You won’t owe a copay or coinsurance for these services regardless of where you stand on your deductible.
How Family Deductibles Work
Family plans add a layer of complexity because there are two common structures: embedded and aggregate deductibles.
With an embedded deductible, each family member has their own individual deductible sitting inside a larger family deductible. Once one person hits their individual amount, insurance begins covering that person’s care, even if the overall family deductible hasn’t been met. For example, a plan might have a $2,000 individual deductible embedded within a $6,000 family deductible. If your child racks up $2,000 in medical bills, their coverage kicks in right away.
With an aggregate deductible (also called non-embedded), no one in the family gets coverage until the entire family deductible is met. Using that same $6,000 figure: if three family members each have around $1,900 in expenses, totaling $5,700, the plan still hasn’t reached the $6,000 threshold and insurance pays nothing yet. This structure can hit families hard when medical costs are spread across multiple members rather than concentrated in one person.
Your plan documents will specify which type you have. If you’re choosing between plans during open enrollment, this distinction can make a real financial difference.
What Happens If You Switch Plans Mid-Year
If you change jobs or switch insurance carriers in the middle of the year, your deductible progress generally does not follow you. You’ll typically start at zero with your new plan.
Some group insurance plans offer what’s called a deductible credit transfer, where the amount you already paid toward your old deductible gets applied to your new one. But this is uncommon, and no law requires insurers to offer it. It’s more likely to happen when an employer switches the entire company to a new carrier than when an individual employee moves to a new job. A new hire at a different company almost never gets credit for what they paid under their previous employer’s plan.
This is worth factoring into any mid-year job change. If you’ve already met a $3,000 deductible by July and then switch employers, you could be looking at another $3,000 before your new plan starts paying its share.
How to Track Your Progress
Every time you receive a covered medical service and a claim is processed, your insurer sends you an Explanation of Benefits (EOB). This document shows your “deductible status,” which is the total amount applied toward your annual deductible so far. It also breaks out how much of each specific bill counted toward the deductible versus other cost-sharing categories.
Most insurers also let you check your deductible progress in real time through their website or mobile app. Look for a “Benefits” section showing your benefit maximums, including how much of your deductible remains. Keeping an eye on this is especially useful late in the year. If you’re close to meeting your deductible in October or November, it may make sense to schedule any procedures or appointments you’ve been putting off before the reset wipes your progress clean.
High-Deductible Plans and HSAs
High-deductible health plans (HDHPs) follow the same once-per-year reset rule but start at higher thresholds. For 2026, the IRS defines an HDHP as any plan with a minimum deductible of $1,700 for individual coverage or $3,400 for family coverage. These plans also cap annual out-of-pocket expenses at $8,500 for individuals and $17,000 for families.
The tradeoff for a higher deductible is typically a lower monthly premium, plus eligibility to open a Health Savings Account (HSA). Money in an HSA rolls over year to year, so even though your deductible resets annually, the savings you’ve set aside to cover it don’t disappear. For people who are generally healthy and don’t expect large medical bills every year, this can soften the impact of resetting a high deductible.
Timing Your Care Around the Reset
Because the deductible resets once a year, the timing of your medical care matters financially. If you’ve already met your deductible, your insurance is actively covering a larger share of your costs for the remainder of the plan year. Scheduling elective procedures, imaging, or specialist visits during this window saves you money compared to waiting until after the reset.
Conversely, if you’re buying a new individual plan late in the year, keep in mind that any medical expenses you incur in December won’t carry over into January. If a procedure can safely wait until January, you’ll at least be building toward the deductible you’ll have for the full upcoming year rather than one that vanishes in weeks.
