That's not how it would work. The IRS wouldn't send you a bill: it'd sent you an offer in the form of a pre-filled tax return. You accept the offer or you submit your own tax return.
Its the insane burden and waste of time for the average person that is the problem.
Imagine how much more productive the entirety of the US would be if tax filing would be simple. The amount of time saved would be enormous, there are approx 140 million tax payers and if everyone would spend just an hour (in reality its probably multiple days) per year doing tax related work you get an idea how much time is wasted.
So you only need to bother with a "self-assessment" tax return if you earn over £1000 of casual income.
And then, if you have less than £1000 of expenses related to that income, you don't have to justify the deductions so you just enter the income as a number and you're done.
Charitable contributions are claimed by the charity at the basic taxpayer rate. So when you donate £1 they can claim 20p from the government.
You only need to itemise your charitable contributions (to claim back the difference between the 40p of tax you paid and 20p the charity got) if you are a higher rate taxpayer, which is something like £70k per year gross, so you're well into <5% of people here.
We'd probably see more monkeying around with the standard deduction. I know for me, and presumably a lot of people (especially those without major mortgage interest), the current standard deduction exceeds the benefits to be had by itemization-- and claiming the trivialities like charitable donations or medical expenses.
The truth is the IRS bill would be wrong and the IRS would have countless challenges and no practical ability to review any in-house type of challenge and all cases would needlessly result in court.
I had a horror story that took 2-3 years to resolve went all the way to tax court for a fraudulent 1099 in the amount of $75k presumably so the company could take a deduction and the IRS was seeking about 30k in taxes/fees/interest. Tax court require an agreement on the facts and issues before trial which the IRS dragged its feet until about 1 week before the agreed order was due when the conceded I was right and owed $0 taxes.
To even get to that point there were about 1/2 dozen phone calls with the IRS which took hours and always resulted in the employee confirming the believe me and I won’t owe anything. There were about 3 formal written responses I provided but IRS kept giving me standard boilerplate letters that I hadn’t proved I wasn’t paid the 1099 income reported and escalating the matter until finally they adjusted my return and forced my hand into filing a petition for tax court. Once in tax court their is supposed to be a stay on the matter until resolved by the court, but the IRS put me in collections, so I filed a motion which the Judge granted in chamber without a hearing to remove me from collections, this was after multiple conversations with the IRS attorney who never did anything but laugh when I called it a IRS automated track of hell and otherwise did nothing to looking into what I felt should have been pretty obvious case of fraud by the company that falsely reported the 1099 income.
This took hundreds of hours and the only way possible I got through it is that I happen to be an attorney.
