Mission and programs · 2024

Mission

Our mission is to encourage, foster and participate in the documentation, preservation and renovation of artifacts, buildings and sites in Sister Bay Area.

  • The Christkindlemakt is a Christmas holiday market that runs for three weekends immediately after Thanksgiving. This is our largest fund raising event requiring 100 volunteers. The proceeds support the main mission of the organization.

    Expenses $132,951 · Revenue $181,731

  • This is our museum. We own 7 acres of land with 19 restored buildings which contain exhibits that are open for tours to the public for a small fee. We also rely on membership fees and fundraising events to support our museum operations.

    Expenses $53,271 · Revenue $74,771

  • This will be our water front museum located off campus. This project will eventually house an historic boat and will have regular historic exhibits. This museum will be open to the public for a small fee and will collect regular membership dues from members to support it's activities.

    Expenses $1,220 · Revenue $97,404

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. Earlier years are each on their own filing page.

The four totals the IRS asks for on Part I of the Form 990, as filed. A dash means the figure was not present on the return — not that it was zero.

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.

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.
