How the mid-year change works

Single trip: the tool uses the rate in effect on that date. A June 30 trip is 72.5¢; a July 1 trip is 76¢ (business).
Monthly log: January–June miles use the H1 rate; July–December miles use the H2 rate. July 1 is the first day of July, so the whole month is H2.
Keep a contemporaneous log (date, miles, business purpose, destination). The IRS can disallow estimates without records — see Pub. 463.
