Does 1BSI Pay Taxes?

Yes. All of them.

While 1BSI is a 501(c)(3) nonprofit and could legally opt out of certain property and sales taxes because of the public good we provide, we choose not to. Being an unquestionable net contributor to our host community matters to us, and paying our share is part of being a good neighbor.

That said, donations to 1BSI may be tax-deductible for donors, depending on individual circumstances. The island pays in. Our supporters get the perks.
