Annual Assessments Explained: Budget Impact & Hidden Costs

Health sharing plans often charge special assessments beyond your monthly contribution. Learn what they are, when to expect them, and how to budget for them. One thing to note before diving in: IRS Publication 969 governs HSA-eligible health plans, and health sharing contributions do not qualify for the self-employed health insurance deduction — a budgeting reality worth knowing upfront.

Assessments vary wildly between plans — some charge them quarterly, others almost never. Use our side-by-side comparison table to see which plans have the most predictable costs. And if you want to forecast your true annual spending (assessments included), our annual cost projector builds a realistic budget based on your household and health profile.

First, let’s untangle what “assessment” actually means

Here’s the thing nobody tells you when you’re shopping: “annual assessment” isn’t one fixed cost. In health sharing it gets used loosely for three completely different line items, and they hit your budget at completely different times. If you lump them together, you’ll either overestimate (and skip a plan that’s actually a great deal) or underestimate (and get blindsided in March when a bill lands).

The three things people call “the assessment”:

• Your monthly share. The predictable number — what you pay every month just to be a member, whether or not you use any care. This is the one most plans quote you up front.
• Your per-incident amount (called an IUA, AHP, or MSP depending on the plan). This is the chunk you pay out of pocket before the membership starts sharing a bill. It only hits when you actually have a medical need — and it can hit more than once in a year.
• Special or supplemental assessments. Extra call-ups some ministries use to cover catastrophic needs above their normal cap. Samaritan’s “Save to Share” is the classic example. This is the closest thing to a true once-a-year surprise.

The first one is on your calendar. The second and third are the budget killers, because they show up when you’re already dealing with a medical situation. Let’s break down each one with the actual numbers from the plans we cover.

The per-incident amount (IUA / AHP / MSP) — the one that bites mid-year

This is the single most misunderstood cost in health sharing, so it’s worth slowing down on. The IUA (Initial Unshareable Amount) is roughly the health-sharing version of a deductible — the amount you cover yourself before the membership shares the rest of a bill. If you want the full mechanics, we wrote a dedicated explainer on what an IUA is and how it works. The short version: you pick your IUA when you enroll, and a lower IUA means a higher monthly share (and vice versa).

The trap is that for most plans, the IUA applies per medical incident, not per year. Break your ankle in February and have an unrelated kidney stone in August? That can be two separate IUAs in the same calendar year. This is where people’s budgets fall apart — they planned for one and got hit with two.

Medi-Share works differently and it’s actually friendlier here: its AHP (Annual Household Portion) is a true annual number that resets each year, more like traditional insurance. Below is what each plan we cover actually charges, straight from their current member terms.

Per-incident amounts and monthly shares come from each plan’s current published member terms. Presidio is quote-based; request a personalized quote for its exact IUA tiers. Always confirm directly with the plan before enrolling.

Notice the spread. A low Samaritan or Sedera IUA ($300–$500) feels great until you remember it can repeat per incident. A Medi-Share AHP of $6,000 looks scary on paper, but it’s capped for the whole year no matter how many separate things go wrong. Neither is “better” — they’re different bets. If you rarely see a doctor, the low per-incident plans win. If you have a year where everything goes sideways, the annual-cap structure protects you.

Special assessments: the true once-a-year surprise

This is what most people mean when they ask about “annual assessments,” and it’s real — but it’s mostly a Samaritan thing. Samaritan’s standard Classic membership shares needs up to $250,000 per incident. For bills above that, they use a separate program called Save to Share, funded by an additional annual contribution from members. So a Samaritan household budgets for its monthly share plus a yearly Save to Share amount if it wants coverage above the $250K cap.

That’s the structure people get burned by — they sign up looking at the monthly number and forget the annual Save to Share line. It’s not hidden (Samaritan is upfront about it), but it’s easy to skip past. We dig into Samaritan’s full cost picture in our Samaritan Ministries review if you’re weighing it specifically.

The other plans we cover sidestep this. Zion and Sedera both share unlimited per need — no annual or lifetime cap — so there’s no “above the cap” special assessment to fund. Medi-Share also has no annual or lifetime sharing cap. CrowdHealth, which is technically crowdfunding rather than a ministry, has no per-event cap either; its model is the flat $60/month advocacy fee plus a variable monthly crowdfunding contribution (up to about $140/month for members under 55). So when people say “CrowdHealth’s costs go up some months,” that’s not a surprise annual assessment — it’s baked into how the model works every month.

What your real annual budget looks like

Forget the marketing number for a second. Your true annual cost is: (monthly share × 12) + the IUA/AHP you’ll realistically hit + any special assessment. Let’s run two honest scenarios for a healthy individual using the lower end of each plan’s monthly range.

Scenario A — a quiet year (no major medical needs):

*CrowdHealth’s $60 advocacy fee is fixed; the variable crowdfunding portion (up to ~$140/mo under 55) is added when the community has needs to fund, so a real-world annual total runs higher than $720. Monthly figures are the low end of each plan’s published individual range and vary by age, IUA choice, and state.

Scenario B — one real medical event (say, an ER trip and follow-up):

Each plan’s lower monthly share usually pairs with its higher IUA/AHP — so the cheap-monthly plans cost more when you actually have a need. That’s the trade-off the monthly number hides.

See the pattern? In a quiet year, the cheapest-monthly plan wins easily. The moment you have one real event, the math flips, because the plans with the lowest monthly shares (Medi-Share, CrowdHealth on the low tiers) tend to pair that with the highest per-incident amount. This is exactly why the monthly price alone is a terrible way to pick a plan. We go deeper on these buried costs in our breakdown of the hidden costs of health sharing.

Who should worry about assessments — and who shouldn’t

You should budget carefully for per-incident costs if:

• You have a family with kids — more people means more chances for separate, unrelated incidents in the same year, and per-need IUAs stack.
• You manage a chronic or recurring condition. Even after the waiting period, recurring needs can mean recurring IUAs depending on how the plan defines an “incident.”
• You chose the lowest monthly share. Cheap monthly almost always means expensive per-incident. Know your number before you need it.
• You’re on Samaritan and want above-$250K protection — build the annual Save to Share contribution into your budget from day one.

You can mostly stop worrying if:

• You’re a healthy individual who rarely uses care. Your real cost is close to the monthly share, full stop.
• You picked a plan with a true annual cap (Medi-Share’s AHP) and you’d rather have one predictable ceiling than a low-but-repeatable number.
• You chose Zion or Sedera, which share unlimited per need — there’s no special assessment hanging over you for catastrophic bills.

The honest caveat

None of this is insurance, and that matters for budgeting. The NAIC makes clear that health sharing plans are not insurance — there’s no legal guarantee of payment, no government backstop, and pre-existing conditions sit in waiting periods that range from 12 months (Samaritan, Medi-Share) to a 12–36 month phase-in (Sedera) to two years of ineligibility (CrowdHealth). A “need” that gets declined isn’t a special assessment — it’s a bill you pay entirely yourself. So when you forecast a year, the most conservative budget assumes a denied or delayed need is possible, especially early in your membership. That’s not us talking down the model; it’s just the realistic floor you should plan against.

The upside, honestly, is that for a lot of healthy people the all-in number — even with one IUA factored in — still lands well under what comparable ACA coverage would cost. KFF data shows the average unsubsidized Silver plan benchmark premium running well above $400/month for a 40-year-old, which is context worth having when you're comparing your all-in health sharing budget to the alternative. The point of this article isn’t to scare you off; it’s to make sure the number you budget is the real number, not the brochure number.

Bottom line

“Annual assessment” is really three separate costs wearing one name: your monthly share (predictable), your IUA or AHP (hits when you have a need, sometimes more than once a year), and special assessments like Samaritan’s Save to Share (a genuine yearly line item if you want above-cap protection). Plans with the lowest monthly price usually carry the highest per-incident amount, so the only fair comparison is the all-in annual figure for your likely usage — not the headline monthly number.
