We do not believe it is necessary to provide a W-9 form to this insurance company, although providing the form should not harm your bank (other than requiring your bank to push some additional paper). Our understanding is that the FATCA withholding requirements that become effective on January 1, 2019, apply only to payments made to non-U.S. financial institutions.
If your bank happens to receive a large volume of payments from Progressive, then it may be prudent to respond by providing a W-9 form.
