The issues…
As online commerce grew, shoppers often did not pay
sales tax. Online retailers were
required to collect taxes only in those states where they had a physical
presence: a retail store, a distribution center (brick & mortar). It wasn't that sales tax wasn't due, but that
it was too complicated to collect. States, counties, and other municipalities
have varying rates and tax different items.
Keeping track of all the tax details was considered a burden for
businesses. Most states require shoppers to keep track of online purchases and
report and pay sales tax through their state income tax filings. Many taxpayers
are either not aware of this requirement or choose to ignore it. Online commerce has grown exponentially. Uncollected sales tax is estimated to be in
the tens of billions of dollars; revenue sorely needed by the states.
