Are they withholding an additional 10% of income, or 10% more tax (110% of the appropriate withholding)?
They are taking 10% more tax. I under withhold any way, it’s about $5.00 a month more on an annual gross salary of $50k (for me).
10% more tax is withheld. If they were taking out $100 in state taxes, now they would take out $110.
Bill O’Reilly got it wrong over and over and over on one of his shows last week. He thought your take-home pay would go down by 10%.
