The adopted all-funds plan uses $6.15 million of cash; this is not the same as an operating deficit in each fund.

Published fund rows differ from the displayed all-funds total by $1 because of source-table presentation rounding.

Peer fiscal rankings are excluded because fund structures and accounting definitions are not reliably comparable.

Monthly tax values are IDOR sales-related warrant disbursements, dated by disbursement month. They are not taxable sales, total Village revenue or budget actuals. Interest is already included; separately published interest and fees are retained in downloads. December 2025 MT and NHMR receipts are published values recovered from IDOR's FY2026 annual workbook, which lacks separate monthly voucher, collection, interest and fee details. Missing tax-code rows remain unavailable. Tax policy changes can affect year-over-year comparisons.
