Sales Tax Collections – Sanibel & Captiva The total state sales tax collected from businesses located in Sanibel (ZIP 33957) and Captiva (ZIP 33924), as reported by the Florida Department of Revenue. Because sales tax is tied to purchases, it serves as an indicator of local spending and economic activity. Figures are shown by the month the sales occurred, not the month the tax was collected. Businesses file and pay the month after their sales, so the most recent month available is typically about two months behind the current date. The latest month is preliminary and may be revised as late returns are received.
