Sales tax in patreon (Patreon)

So I've been looking about the new tax thing patreon is implementing starting June 1st. It seems patreon is gonna charge a tax to patrons starting June 1st. I don't know how much it is, but I want you guys to be aware of it, specially the 1 usd patreons. Actually patreon recommended me to remove tiers under 5 usd. What do you guys think? What could I do to make things easier to deal with?
