Our analysis of the full Joint Committee on Taxation tables of the flawed GOP megabill: a $1T tax cut for the top 1% and a staggering $2.4T tax cut for the top 10%.

Tax cuts of around $500B for households in the bottom 60%--the very folks who also face the brunt of cuts to Medicaid and SNAP.

We are excited to launch a project to remake federal tax administration. Effective tax administration is critical to the federal government, but has recently faced drastic challenges over the last six months.

Germany eyes 10% digital tax on tech giants Proposed levy would affect companies including Google and Meta

Okay, this is very significant news! A 10% tax on revenues (not profits) would not only break new ground in Germany, it’d be by far the highest digital tax rate in Europe.

A key part of the reasoning:

"The Worldwide and Retaliatory Tariffs lack any identifiable limits and thus fall outside the scope of Β§ 1702."

Another troubling own goal that will hurt US exports, US innovation, and US prosperity. (International student tuition is a service export.)

To say nothing to the damage to US standing in the world, international relations, and future partnerships... as well as the students themselves!

The thing that is particularly noteworthy here - to me at least - is that effective tax rates (i.e. what's actually paid) have *increased* recently. This aligns with OECD data (which uses a different methodology). It might be the first time in 40 or 50 years that such a broad increase has happened.

"Such β€˜commercialisation’ of citizenship is incompatible with the basic concept of Union citizenship as defined by the Treaties... Malta has infringed EU law"

Trump eyes targeting more tax-exempt groups while denouncing Harvard President Donald Trump defended his administration's moves to strip Harvard of its tax-exempt status and suggested more organizations could be in the IRS's crosshairs.

The silence from Republican lawmakers re: Trump’s suggestions that IRS audit specific tax exempt orgs is deafening. Here’s a short history of how Rs and Ds responded to prior IRS reviews of tax exempts when *no* political appointees, let alone the President, were interfering. 1/

Steel Tariffs and U.S. Jobs Revisited | Econofact The 2018 tariffs raised domestic steel prices, putting downstream U.S. manufacturing firms at a disadvantage relative to foreign competition.

In light of latest of steel/aluminum tariff threats, it's a good time to review the evidence.

This work finds job losses in metals-using sectors outweigh job gains in metal sectors ~75 to 1.
