I won't get lured into the political dumpster fire of this thread...don't you think it is just a short-term leveraging strategy?
What happened to NAFTA and USMCA ?
"we changed our minds" ?????
@Norm, do you file for a return of VAT, GST, HST after going to Canada?
GST is a funny one - we kinda do the same thing.
If I purchase tile at HD, even with a reseller certificate, the tile is doing what it is made to do, so I'm charged tax,
then when I bill the customer I charge them tax on the material (second tax for this) plus tax on the labor.
In some cases I can avoid the double tax if I line item the supplies, and don't upcharge.
There is also the ST-8 to make an improvement tax exempt - use this sparingly, esp if only some of the project is exempt.....
But you should be using a reseller tax certificate and not paying taxes at Home Depot if you're a legitimate business if you're reselling the tile.
Sales tax is only for the end customer.
