Other states are like this too. US tax revenue is 27.1% of GDP. In NZ it is 32%. France is at 46.2%.

Back around 2000, the then Labour government of NZ commissioned a study among about 8 different economists to determine what was the optimal tax revenue as % of GDP for maximizing GDP growth. You can buy the results on Amazon for hundreds of dollars, but the gist of the ~8 papers submitted was that the were all fairly close agreement and came in with figures between 17% and 24% of GDP... quite in line with Pharoah actually.
In China it's 17.5% of GDP. Singapore is at 14.1%.
Be careful with the "Tax" metric. I've read that North Korea has no taxes and could not believe it, but found to be true. But if you compare their spending related to their GDP, its pretty high. I dont know whats going on there, but maybe they sell services without taxes, but the profit goes to the government, or maybe they give another anem to that.
A government can also tax you without "taxes", just by printin money and eating your purchase power.
I suggest to analyse government spending as % of GDP
