Mission

TO SUPPORT THE AMERICAN MUSEUM IN BRITAIN THROUGH FUNDRAISING ACTIVITIES IN THE UNITED STATES.

Each tax year counts once: when a return was amended, only the latest return for that period is used below (superseded returns stay listed, greyed, under Finances).

People paid by the organization

1 person paid across every filing: current people first, then by total pay from this organization. Organizations counts every nonprofit each person appears on.

Officers and directors, no compensation reported

14 people listed on the returns with $0 (or no amount) in every compensation column: current people first. Hours are as filed on the latest return each person appears on.

People by year

Highest-paid independent contractors

No independent contractors reported.

Who gave

Contributor names are not public for this form type.

Public charities filing Form 990 or 990-EZ report large donors on Schedule B, but the IRS withholds their names and addresses from public copies. Private foundations (990-PF) are different: their contributors are public.

Finances

Newest first. Each filing: its name on one row, its figures on the row beneath. Greyed filings are superseded by a later return for the same period and are left out everywhere else on this page.

Connected to

Organizations that list some of the same people on their returns (officers, directors, key employees on this organization’s latest return), and related organizations it lists on Schedule R.

Funders of this organization

20 grantors reported grants to this organization, $2,791,175 in all, tax years 2009 to 2025. Exact: the grantor wrote this organization's EIN. Fuzzy: the grantor wrote only a name (foundations' 990-PF has no EIN field), matched to the same or a near-identical name in the same state; the name as filed is shown. From the latest return for each grantor and year, so amended returns aren't counted twice. CSV

Where the money went

Every expense line on each return, biggest first: Form 990 Part IX (with its program, management and fundraising columns), 990-EZ Part I, or 990-PF Part I. Event marks lines the organization itself describes as events. “Events” in each summary adds those lines, conferences and meetings, and the direct costs of fundraising events. Unusual is not the same as improper. Many of these patterns have ordinary explanations. Check the filing.
