The third edition of our flagship CIT publication, Corporate Tax Statistics, is out today – huge congratulations to the team who put this together. Some highlights in a thread: 1/
First, the decline in statutory CIT rates continues, albeit at a slightly more modest pace last year. It's particularly acute when considering zero-tax jurisdictions.
In spite of these declining rates, CIT revenues are broadly holding up (NB this is pre-pandemic)
Side note: for more on why this is, see this talk () by @desaimihira as well as this @CESifoGroup paper by my colleague Felix Hugger & others (papers.ssrn.com/sol3/papers.cf…). Tl; dr the answer seems to be both higher profits and also broader tax bases.
@desaimihira@CESifoGroup Next, we also have new data on marginal effective tax rates – taking the statutory rate but also tax bases into account. Here we can see that on a breakeven investment, effective tax rates are essentially zero – normal returns are often untaxed – for the bottom quartile.
@desaimihira@CESifoGroup This year we also have new indicators showing the impact of R&D tax credits on effective tax rates – in about half of the countries covered, the cost of capital is below zero once R&D credits are accounted for – governments are essentially subsidising R&D using the tax system.
@desaimihira@CESifoGroup Finally - it merits a separate thread but we have substantially expanded the coverage of our #CbCR statistics, which now cover about 95% of all CbCRs exchanged.
This expansion to new countries is not always easy but every country is a little victory for tax transparency and is a big legacy of the BEPS project that continues to pay dividends. Much credit due to @ali_giulia for getting so many new countries on board this year.
A few words on the new data and the international tax reforms. First, the decline in corporate tax rates has been pronounced.
Second, our new data on also show that the decline in CIT isn't just about statutory rates. It is also about tax expenditures that countries use to attract mobile assets & activity such as intangibles through IP regimes – our data shows just how low these special rates can be.
Third, our CbCR data show continuing BEPS activity (albeit with a significant data lag – its 2017 data). We can see more profits and more related party revenues in investment hubs (which are often but not always low-taxed) than we can in other jurisdictions, as well as
