CLI Tax Editor for Magento 2 adds a CLI command to update tax rates. This is pretty useful for general tax rate changes in a country, which must be applied exactly at a specific date. It is possible to define a new rate for a range of tax rate IDs.
$ bin/magento tax:rates:edit [--ids[="..."]] [--rate[="..."]] [--update-titles]
--ids
Comma-separated list of tax rate IDs
--rate
The new rate (integer or float with decimal point)
--update-titles
Update the code and the titles of the tax rate as well
