House Republicans are racing to extend tax cuts that are scheduled to expire—after 2025.

Even though the legislation dubbed “Tax Reform 2.0” isn’t likely to become law this year or have significant practical effect on individual tax returns until today’s sixth-graders are in college, Republicans see advantages in voting now.

Most immediately, the planned September vote will give GOP House members a campaign talking point ahead of the November midterm elections. For them, it’s a way to highlight partisan contrasts and continued economic growth since last year’s tax law, which passed without a single Democratic vote. Extending the tax cuts, they say, will bolster investors’ confidence.

“We just want to give people certainty that we want to extend the individual tax cuts,” said Rep. Tom Rice (R., S.C.). “The longer it goes, the harder it can get. We want to do it while we have the majority, certainly, and do whatever we can to get it across the finish line.”
