Why was so much taken out of my bonus in Massachusetts?
On a $10,000 bonus in Massachusetts, someone earning $60,000 a year (paid every two weeks) keeps about $6,489 under the flat method and $5,992 under the aggregate method, a difference of $497. The aggregate method withholds as if you earned that large paycheck every pay period, which pushes the bonus into a higher withholding bracket.

Withholding is not your final tax: the bonus is taxed at your normal rates on your return, and any extra comes back as a refund.

No. On your tax return a bonus is ordinary income, taxed at the same rates as your other pay. Only the amount withheld from the bonus check can differ.
