Rate files are available the second to last business day of the month, by 12pm PST.
- The modified date for a rate file contains the previous month because they were prepared ahead of time.
- Ex: The tax rate file for October has a modified or status date of September.
- Rate emails are never sent in the middle of the month. New state tax rates (and their dates) are reflected in the next monthly rate file you receive.
- Rate files are updated whether or not you receive the email notification.
