Current US population: 324 million people, 250 million adults.
Poverty line income: $22,000 for the family of four (it is hard to estimate individual poverty line income, but it's more than $22,000 / 4. Let's say $12,000, which is $1000 / month).
Total cost of universal basic income of $1,000/month for the US: $3 trillion per year.
Total US income tax revenue: $1.8 trillion for personal income tax, $0.4 trillion for corporate income tax.
For instance, if the cost of "basic life necessities" was somehow $5/yr, but incomes (and tax revenues) similar to today (... presumably people are spending an awful lot on luxury goods?), it could certainly be all three of those things.
It may be the case that that is somehow impossible, but that's a case that you need to make in some way other than listing off what the current numbers happen to be.
Everyone gets the UBI, but the more money you make, the more you're paying in additional taxes to support the UBI. At some threshold you're paying as much in additional taxes as your making in UBI payments. Past another threshold and you're paying more in additional taxes than you're taking in.
Effectively you only need to provide the full UBI for people making very little per month.
