Per the Indiana Department of Revenue, the rate of county tax you pay is based on where you were living in Indiana on January 1, 2025 for your 2025 taxes. Check this link for the Indiana Department of Revenue: FAQ for Indiana Taxes .
Since it looks like your employer only withheld tax for the first county, there should be no issue.
For 2026, just be sure that the correct county tax is being withheld from where you are living as of January 1, 2026. If not, you should make your employer aware of this so it can be corrected quickly.
