At least here in Canada, sellers are legally obligated to remit sales taxes, even if they do not explicitly collect them. The buyer does not need to do anything.

I made this mistake when I first starting selling online, which stung. Setting up a tax ID in Canada was very easy. Now that I am selling in the US, I am just beginning to explore the issue, and it is notably less easy.

So if you "get away" with not paying sales tax online, it is likely that the sales tax was simply baked into the price.

this does not reflect the situation in the US, where krebby appears to be located. (i checked first.)

here's a little page from washington state on it, which matches my understanding of the situation in most other states: https://dor.wa.gov/get-form-or-publication/publications-subj...

> Have you ever made a retail purchase and the invoice didn’t include retail sales tax? This may occasionally occur, especially if you purchase items over the internet or from out-of-state vendors. ... However, the buyer has a responsibility to pay use tax to the Department of Revenue even if the seller doesn’t collect it.

> Also, an invoice should never have a single figure that “includes retail sales tax.” If you receive such an invoice, contact the vendor and ask for a new invoice with the retail sales tax separately stated. Washington law requires that customer sales slips, contracts, invoices or other sales documents separately state the amount of retail sales tax due.

Oh very good. The "let's say you did something bad therefore the bad that you accuse someone else of doing isn't bad"

If there is a poorer argument against wrongdoing than this I don't know it.

That would take more work to pay more taxes. Apple did work (setting up a subsidiary) to avoid paying taxes.

I set up my 401k. That was work. I've also done the mega-backdoor Roth IRA last year, and will do it again this year. Am I a bad man?

Courts have ruled in favor of the mega-backdoor Roth IRA as a legitimate intended use of the tax code.

That kind of comment is called 'whataboutism'.
