Show me where and when taxes have been cut, but not raised again. It doesn't happen. However a major victory for taxpayers back in 1981 was when Congress indexed tax brackets for inflation. Before that time, Congress let inflation do the dirty work of putting taxpayers into higher tax brackets rather than voting for the tax increase. At least if they vote for a tax increase later, then we know who we can vote against in the next election.
Many states have provisions in their constitution that make it more difficult to raise taxes.
Over a dozen states require a two thirds vote or three fifths vote to raise taxes. A few states require voter approval instead of legislative approval. Congressman Barton has a proposed tax limitation constitutional amendment that is expected to come for a vote next month. His bill would require two-thirds vote to pass a tax increase. We also have additional protection in a rule passed by the house in 1995.
