How the US Corporate Tax Rate Compares Globally in 2026

In this episode of The Tax Policy Podcast, Lucas and Luna drill into a single number: the US combined federal and state corporate tax rate of 25.8 percent as of May 2026. They compare it to the OECD average, explain why Ireland's 12.5 percent rate is less relevant than its effective rate on tech giants, and walk through how the 2017 Tax Cuts and Jobs Act shifted the US from the highest corporate rate in the developed world to roughly the middle of the pack. Luna challenges whether the statutory rate even matters when loopholes and credits drive effective rates much lower — for example, how profitable US companies paid an average effective rate of just 10.7 percent between 2018 and 2023. Lucas brings in the OECD's global minimum tax of 15 percent, the political dynamics of the 2025 tax debate, and why a 25.8 percent headline number doesn't tell you who actually pays. The conversation stays grounded in a single case: the semiconductor industry, where federal CHIPS Act credits have pushed effective rates for some manufacturers below 5 percent. A concrete, numbers-first episode for anyone who wants to understand where the US actually stands on corporate taxation right now. #CorporateTax #TaxPolicy #OECD #GlobalMinimumTax #PillarTwo #UsTaxRate #IrelandTax #EffectiveTaxRate #TaxCutsAndJobsAct #CHIPSAct #Semiconductors #TaxCompetition #Economics #Business #FexingoBusiness #BusinessPodcast #TaxPolicyPodcast #LucasAndLuna Keep every episode free: buymeacoffee.com/fexingo
