The tax rate in Boone County increases to 0.0171 from 0.017, effective October 1, 2026. ### **Departmental Notice Updated Again in December** The DOR will issue a new notice in December that will announce any county income tax rate changes effective January 1, 2027. ### **County Tax Rates** All 92 of Indiana’s counties impose a county income tax on residents of the county and on nonresidents – who do not reside in another Indiana county – with a principal place of business or employment in the county. Each county has one income tax rate (i.e., tax rates are the same for residents and nonresidents). Employers withhold state and county income taxes from employees’ wages. --- Interested in more state and local payroll coverage? PayrollOrg’s **[*PayState Update*](https://ebiz.payroll.org/ebusiness/ProductCatalog/Product.aspx?ID=19)**eNewsletter is perfect for you. --- *Lia Coniglio, Esq., is Managing Editor of* PayState Update *and Senior Manager of State Payroll Information Resources for PayrollOrg.* ### Search ![payroll-logo-white](https://blogs.payroll.org/hs-fs/hubfs/payroll-logo-white.png?width=200&name=payroll-logo-white.png "payroll-logo-white") [Privacy Policy](http://www.americanpayroll.org/privacy/)     |     Acceptable Use ©[PayrollOrg](http://payroll.org) [![soc-fb](https://blogs.payroll.org/hubfs/ct-23-assets/footer-icon_fb.svg "soc-fb")](https://www.facebook.com/PayrollOrg) [![soc-in](https://blogs.payroll.org/hubfs/ct-23-assets/footer-icon_li.svg "soc-in")](https://www.linkedin.com/company/payroll-org/mycompany/) [![Twitter-X-White-Logo-PNG](https://blogs.payroll.org/hs-fs/hubfs/Twitter-X-White-Logo-PNG.png?width=20&height=19&name=Twitter-X-White-Logo-PNG.png)](https://twitter.com/PayNews)
