Here's my take:
This is not raising taxes. Period. It sounds like the article is attributing the burden to those earning under $200k, saying that they will get audited more and have to actually pay the correct amount of taxes. This isn't raising taxes, this is catching people who are not paying the correct amount of taxes and forcing them to do so like all of us are compelled to do by law. I feel 0 sympathy for someone who has been underpaying (intentionally or unintentionally) and now has to pay what is due according to tax law. In conclusion, this is not raising taxes, it is enforcing the tax code. Everyone doing things by the book should want this. See references below:
"A key provision in the Inflation Reduction Act — which throws an extra $80 billion to the IRS to improve the agency’s collection of under-reported income — will end up targeting small business owners to pay for the legislation."
" Accordingly, tax experts warn that the IRS’s audits will be far more painful and costly for small business owners — even for those who think they’re filing their taxes correctly."
“The approach here is to double the IRS workforce, take the leash off, and see how much they can collect,” Hinchman adds. “I think they’ll collect it but it will be quite painful.”
