Mission and programs · 2024

Mission

SIL advocates, builds capacity, and works with local communities to apply language expertise that advances meaningful development, education, and engagement with Scripture. Continue on Schedule O

Activities or mission (Part I)

SIL is a global faith-based organization that walks with marginalized language communities to help them use their languages to know God, learn freely, and thrive in community. Continue on Schedule O

  • Language Engagements - SIL works with over 1,500 communities worldwide (impacting more than 950 million people) as they build their capacity for sustainable development with their own languages. Program engagements include language development that involves ongoing planned actions that a language community takes to ensure that its language continues to serve its needs and goals. SIL's expertise includes training and consulting in linguistic analysis, orthography and writing systems development, literature development (including translation) and mother tongue-based multilingual education and literacy. SIL publishes Ethnologue, an authoritative resource on world languages, referencing more than 7,000 languages. Continue on Schedule O.

    Expenses $17,218,425 · Grants $3,831,157 · Revenue $1,613,096

  • Logistics - SIL works with non-dominant language communities who may reside in remote locations. It is often necessary for SIL to provide services to its staff that are unavailable in the local economy, such as housing, schools for dependent children, communications services, transportation, health care and access to food and supplies.

    Expenses $14,539,612 · Grants $9,754 · Revenue $7,595,137

  • Language Services - SIL has three primary areas of language services: training in language development and multilingual education, and materials development and publications. 1) Training in language development and multilingual education: In addition to working with communities at the local level, SIL is an acknowledged leader in formal academic programs for the components of cross-cultural language-based service. SIL works in partnership with more than 20 institutions around the world to offer classroom and online training in applied linguistics and related subjects. SIL offers technical expertise and training to support the decisions of both local and diaspora communities about how to maintain their cultures and use their languages to address their changing needs. Continue on Schedule O.

    Expenses $13,276,138 · Grants $1,214,930 · Revenue $1,971,991

The first 25 listed. Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. A Schedule J breakdown is as filed: base pay, bonus, other, deferred compensation and nontaxable benefits from this organization, with any from related organizations beside each, and the filer's own total. It is shown with the Part VII listing of the same name on the same return. The form gives no key between the two, so that pairing is ours, and is marked matched by us. Earlier years are each on their own filing page.

Nonprofiteer parses Forms 990, 990-EZ and 990-PF, in a window of recent tax years. These returns are recorded from the IRS e-file index, so their figures were extracted by that index rather than read from the return here — treat them as a different source from the filings above, not as more of the same record. A dash means the index carries no figure; Form 990-T listings carry none at all. Showing the 10 most recent; the API carries the rest.

Other IRS files

Auto-Revocation List

Not listed. The IRS publishes this list for organizations whose exemption was automatically revoked for failing to file for three consecutive years.

Publication 78

Listed as of 13 October 2026, under deductibility PC.

These are two separate IRS files on two separate schedules, shown as published and not reconciled with each other. Neither is a statement about whether a contribution is deductible today: 19,245 organizations appear in Publication 78 while the IRS's own revocation file lists them as currently revoked, more than half of those revoked before 2019. Absence from Publication 78 is evidence of nothing, and presence is not evidence either. Verify current status with the IRS before relying on it.
