The IRS payable in 2022 is unchanged, however, the monthly withholding tax will undergo slight adjustments.
Due to the lead of the State Budget proposal for 2022, in next year the IRS will not change. The tax payable will be the same for most taxpayers, with slight exceptions.
Even so, the IRS withholding tables, that is, an advance payment of the tax made by employees and pensioners, may have certain changes, precisely because they are just that, just a withholding on account of the tax that will be paid, and in general, the withholding is even made above the necessary, so there are refunds.
See
here the new tables, which show how much will be withheld every month from January, from next year on.
And also compare
here with those in effect in 2021.
