APC Waiver Eligibility: How Publisher and Country-Income Rules Actually Work

Most article processing charge (APC) waiver and discount programs are not a single, uniform policy — they are decided by two largely independent mechanisms that a given publisher may run in parallel: a geographic, country-income-based tier applied automatically from the corresponding author’s institutional affiliation, and a separate need-based request a corresponding author can make regardless of geography. This guide covers how each mechanism actually works, what determines eligibility in practice, and where publisher policies genuinely differ, so a research administrator or journal-submissions staffer can check a specific case rather than assume a general country list applies. For the underlying fee itself, see CASRAI’s article processing charge dictionary entry and the companion guide on how APCs work, which this page assumes as background.

The two eligibility mechanisms, and why they get conflated

Coverage of ‘APC waivers’ online often blurs two different things:

• Automatic geographic/income-based waivers. A tiered discount (commonly a full waiver at the lowest income tier, a partial discount at a middle tier) applied without any request from the author, based purely on the corresponding author’s institutional affiliation at submission. This is the mechanism most large commercial and society publishers use, and it is where institutional waiver programme-style eligibility usually sits.
• Need-based fee assistance, requested individually. A discretionary request process, open to any corresponding author regardless of country, used when institutional or funder support genuinely isn’t available. PLOS’s Publication Fee Assistance program is the most visible example of this model; CASRAI’s fee waiver entry covers the general concept.

A given journal may offer one, both, or neither, and the two are evaluated on entirely different criteria — one is a lookup against a country list, the other is a case-by-case judgment call by the publisher’s fee-assistance team. Confirm which mechanism (or both) a specific journal runs before assuming a rejection under one also forecloses the other.

The Research4Life country-income framework

The geographic tier most large publishers use is not usually built in-house from scratch. Research4Life — the public-private partnership among UN agencies (WHO, FAO, UNEP, WIPO, ILO), Yale and Cornell University Libraries, and a large group of participating publishers — maintains an income-based country-eligibility list originally built for its discounted-access programs (Hinari, AGORA, OARE, ARDI, GOALI) and now widely reused by publishers for APC relief. The general shape of that framework, consistent across the publisher policies referenced below: a lowest-income tier of countries qualifies for a full (100%) APC waiver, and a second, lower-middle-income tier qualifies for a partial discount (commonly 50%), with eligibility checked automatically against the corresponding author’s institutional affiliation rather than the author’s personal nationality or citizenship.

Two things to verify directly rather than assume from a secondary source: which specific countries sit in which tier changes periodically as World Bank income classifications are updated, and not every publisher that references Research4Life’s list applies it identically (some restrict it to fully open-access journals only, some extend a discount tier further than others). Research4Life publishes its own current list and an APC-link lookup tool directly at research4life.org/apc-waivers — treat that page, not a cached secondary summary, as the source of record before advising a specific author.

How eligibility actually plays out by publisher

Waiver eligibility, the exact discount tier, and which journals participate all vary by publisher — the pattern below is what each publisher states on its own current policy page; check that page directly before relying on a specific figure, since these lists and percentages are revised periodically.

Wiley

Wiley publishes an automatic, affiliation-based two-tier structure on its own author-resources site: a full-waiver tier and a 50%-discount tier, restricted to Wiley’s fully open-access journals (hybrid journals, where OA is a paid option within an otherwise subscription title, are explicitly excluded). There is no application — eligibility is checked automatically from the corresponding author’s affiliation at submission, and discounts do not stack with other offers. Wiley also runs a separate purchasing-power-parity-based regional pilot for Latin American authors (launched in a subset of journals from January 2025), offering a graduated discount scale rather than the standard two-tier structure for the countries it covers. Source: Wiley’s own current waivers-and-discounts policy at authors.wiley.com — verify country-list membership and pilot scope there directly, since both are subject to change.

PLOS

PLOS runs both mechanisms. Its Global Participation Initiative applies an automatic, affiliation-based waiver for corresponding authors from qualifying lower-income countries. Separately, PLOS’s Publication Fee Assistance program is a need-based request open to any corresponding author who can show that institutional or funder support genuinely isn’t available — PLOS states explicitly that lack of funds should not be a barrier to open-access publication under this program. This dual structure is why PLOS is a useful comparison case: it shows the geographic and need-based mechanisms operating side by side at the same publisher rather than as alternatives. Verify current qualifying-country membership and the fee-assistance request process directly at plos.org before advising a specific author, since PLOS updates program pages independently of its journal-specific fee schedules.

Elsevier, Springer Nature, and other large publishers

Elsevier, Springer Nature, Oxford University Press, SAGE, and most other large publishers of APC-funded open-access journals maintain some version of the same automatic geographic-waiver structure, generally referencing Research4Life-derived country eligibility for their fully open-access titles. Precise current figures — which discount tier applies, whether it extends to hybrid open-access options, and which journals are excluded — differ by publisher and are revised on each publisher’s own schedule; this guide does not reproduce specific percentages or country counts for these publishers beyond what’s already stated because sourcing directly from each publisher’s current policy page (rather than a secondary summary) is the only reliable way to get a figure that’s still accurate by the time you read it. Check the specific journal’s ‘open access’ or ‘fees and funding’ policy page — most publishers now surface a waiver-eligibility checker or explicit policy statement there rather than requiring you to cross-reference a separate country list manually.

What determines eligibility in practice

• It’s the corresponding author’s institutional affiliation, not nationality. A researcher who is a national of a waiver-eligible country but affiliated with an institution elsewhere typically does not qualify, and vice versa — eligibility follows the address on the manuscript, checked at submission.
• Fully open-access journals are covered more consistently than hybrid options. Several major publishers, Wiley among them, explicitly restrict automatic geographic waivers to their fully OA journals, excluding the pay-per-article OA option inside an otherwise subscription (hybrid) journal. If the journal in question is hybrid, don’t assume the same waiver policy applies — check separately.
• Automatic tiers require no application; need-based assistance does. Don’t submit a formal fee-assistance request for a country that already qualifies automatically, and don’t assume automatic geographic eligibility exists for a country that doesn’t — the two processes are separate and are usually described on different pages of the same publisher’s site.
• Co-authorship across eligibility tiers is publisher-specific. Where a paper has multiple institutional affiliations spanning different eligibility tiers, which affiliation counts (typically the corresponding author’s) and whether that changes if the corresponding author changes during revision are questions to confirm with the specific journal’s editorial office rather than assume.

Where APC waivers fit alongside other cost-relief routes

A geographic or need-based waiver is one of several distinct mechanisms that can reduce or eliminate what an author actually pays, and they are not mutually exclusive with the others in principle (though a given journal may restrict combining them):

• An institution’s own APC reimbursement arrangement with a funder, distinct from a publisher-side waiver.
• Read and Publish (transformative) agreements, which cover APCs for eligible corresponding authors at subscribing institutions regardless of country-income tier.
• Publishing in a no-fee diamond open access journal in the first place, which sidesteps the waiver question entirely because there is no APC to waive.

Where more than one of these could apply, checking the journal’s transformative-agreement eligibility first is usually worth doing before assuming a geographic waiver is the only relief available — an R&P agreement often covers the full fee with no income-tier restriction at all.

A practical eligibility checklist

1. Identify the specific journal (not just the publisher) — waiver participation is frequently set at journal level, especially for hybrid titles.
2. Confirm the corresponding author’s institutional affiliation as it will appear on the manuscript — this, not the author’s citizenship, is what gets checked.
3. Check whether the target journal is fully open access or hybrid — several publishers restrict automatic waivers to fully-OA titles.
4. Look up the publisher’s current waiver/discount policy page directly (not a cached list) for the applicable country tier and percentage.
5. If no automatic tier applies, check separately whether the publisher runs a need-based fee-assistance program open to a direct request.
6. Check whether the author’s institution has a Read and Publish agreement with the publisher before relying on a waiver at all — it may cover the fee independent of country eligibility.

Frequently asked questions

Does an APC waiver depend on the author’s nationality or their institution?

Institution. Eligibility for the automatic geographic tier that most large publishers run is checked against the corresponding author’s institutional affiliation at the time of submission, not personal citizenship or nationality.

Do all open-access journals from a given publisher offer the same waiver?

No. Waiver and discount policies are frequently set at the journal level, not uniformly across a publisher’s entire portfolio, and several publishers explicitly exclude hybrid open-access options from automatic geographic waivers even when their fully open-access titles are covered. Check the specific journal’s own policy page.

Is a country-income waiver the same as a need-based fee-assistance request?

No — they’re two different mechanisms. A geographic waiver is applied automatically from institutional affiliation with no application; a need-based program (PLOS’s Publication Fee Assistance is the most visible example) requires the corresponding author to make an individual request explaining why institutional or funder support isn’t available.

Where do publishers get their country-eligibility lists?

Most large publishers reference Research4Life’s income-based country classification, originally built for its discounted-access programs (Hinari, AGORA, OARE, ARDI, GOALI), rather than building an independent list. Not every publisher applies it identically, so check the specific publisher’s current policy rather than assuming the Research4Life list transfers directly.

Can a Read and Publish agreement and a geographic APC waiver both apply to the same article?

Usually only one applies, and most publishers don’t allow stacking. If the corresponding author’s institution has a Read and Publish agreement with the publisher, that typically takes precedence and covers the fee regardless of country-income tier — check the specific agreement and journal before assuming a geographic waiver is still needed.
