Unfortunately tax really doesn't pay for any of that. Any more than National insurance covers the Dole or the State Pension.
It's all a con trick for the hard of accounting.
The public sector is provisioned by the government spending money - essentially on an overdraft at the Bank of England. That then generates taxation as a matter of construction for any non-zero tax rate - automatically clearing the overdraft. The remaining income moves onto the next person in the income chain and the process repeats until the money disappears in taxation. It's a mathematical progression.
So government spending is a matter of whether there are real resources available to do what they need to do. If there is, then they can be deployed for the public purpose.
Taxation is there to stop the economy overheating and there being too much demand for certain resources. How much taxation is required depends upon how much excess saving there is (ie people essentially taxing themselves by not spending or by paying down debt).
To sum up in monetary terms government spending causes the taxation and saving necessary to pay for that spending.
Now distributionally you can argue that it is unfair that the self-employed are taxed differently from the employed. And you'd be right - there is no good reason that the burden should be shared in that unfair way. But your taxation or lack of it still doesn't actually pay for anything overall.
