This question concerns a narrow factual dispute regarding the Inflation Reduction Act. Will audit rates on those making less that $400k increase?

See here (https://www.cnn.com/2022/08/11/politics/irs-inflation-act-funding-audit-enforcement/index.html) and here (https://www.forbes.com/sites/danielmayo/2022/08/12/will-the-inflation-reduction-act-increase-irs-tax-audits/?sh=96f32ab513d0) for a bit of context. The claim that audit rates will increase has been dubbed (by Janet Yellen, among others) "misinformation".

This question resolves to the factor by which audit rates increase, as measured by the ratio of percentage of tax filings on incomes <$400k that are audited in 2023 to that in 2021. If the increase is more than a factor of 2, this question resolves to 2.

This question resolves N/A if the relevant provisions of the IRA fail to meaningfully take effect.

Be warned that the exact terms of resolution may be tweaked over the next few days as I get feedback. I suggest betting based on the spirit of the question.
