I think the main worry here is not those tax cuts per se, at a 'normal' time markets would have clapped, it's that they mean higher deficit at a time when national debt has already ballooned during Covid, and that they push inflation higher and the Pound lower when the BoE is trying to do the opposite with steep interest rates rises as a consequence.
As per actual IMF statement: "given elevated inflation pressures in many countries, including the UK, we do not recommend large and untargeted fiscal packages at this juncture, as it is important that fiscal policy does not work at cross purposes to monetary policy."
