I agree. Until the Marketplace Fairness Act (in case you aren't aware, there is a bill to be passed possibly) to start charging tax on transactions outside your state of business too but with threshold limits based on revenues. I think the proposal is $1M and above, so I dont care abt it at the moment :))
In the United States, currently you charge tax to the customer for online sales only if the sale is within the state of business (identified by shipping address being within the state of business). Same would be the case with Florida. But keep in mind, that Sales and Use Tax rates could vary. There could components of State Sales Tax at flat % value and then county and district level taxes.
For example for the State of Texas, I charge 8.25% split as 6.25% for the state and then 1% for county and 1% for some metropolitan blah..blah.. This info is important when you file your quarterly sales tax return where you will need to showcase the total value of your sales (in and out of state combined), taxable sales within state and then provide split on the calculation. Would you be penalized if the split isnt provided? As far as I know - NO. You would not be penalized as long as you pay the net value (which in my case is 8.25%).
I did a quick google search and found this link for Florida Sales Tax - Link hidden: Login to view
If you read carefully under sales and use tax, I quote from the page - "Sales and use tax rates: Florida's sales and use tax rate is 6%. Discretionary sales surtax (also called county tax) is imposed by many Florida counties and applies to most transactions subject to sales tax. The Department of Revenue collects both taxes and distributes the surtax back to the counties. The discretionary sales surtax rate depends on the county. Form DR-15DSS lists the counties and their rates."
Hope this helps!
