Montana Republicans cut income taxes and moved to a flat rate. The property tax surge from rapid appreciation has been a top political issue — the legislature passed property tax relief measures. The no-sales-tax environment (shared with Oregon and New Hampshire) gives Montana a competitive advantage.
