The rate of inflation is the percent change in the implicit price deflator for personal consumption as published by the Bureau of Economic Analysis by September 25th.

The most recent publication available on September 25th was the September publication. For this reason, we used the second quarter values to calculate the percent change in the implicit price deflator for personal consumption for taxes due in 2026.

We calculate the percent change by dividing the Quarter 2 2025 number by the Quarter 2 2024 number, subtracting one, and then multiplying by 100. We used the following values in the calculation this year:

Quarter 2 2024 123.401
Quarter 2 2025 126.416
