The Internet as a Tax Haven? The Effect of the Internet on Tax Competition

If online transactions are tax-free, increased online shopping may lower tax rates as jurisdictions seek to reduce tax avoidance; but, if online firms remit taxes, online sales may put upward pressure on tax rates because the internet enforces destination-based taxes.
