Credit is honestly cheap enough that, if you really wanted to invest money that is a liability from the second you earn it, you could.
All other things being equal, if the government earns the money upfront instead of having to wait, tax rates can decrease slightly for the same amount of income. I live in a PAYG country, and given higher rates of tax-default and tax-stress in non-PAYG countries, I prefer PAYG.
