Connecticut bonus tax calculator
A $5,000 bonus in Connecticut keeps about $3,217 after federal withholding at 22%, Social Security and Medicare and state tax. Connecticut takes its share on top of the federal 22%.
How Connecticut taxes a bonus
On a $60,000 salary, a $5,000 bonus adds about $275 to the year’s Connecticut income tax, 5.5% of the bonus, and $25 to CT Paid Leave. That is the extra tax for the year from adding the bonus to the salary, computed by the same engine as the paycheck calculator.
It is not necessarily what payroll withholds on the bonus check. Many states publish their own supplemental withholding rate or method; the Connecticut Department of Revenue Services employer guide is where to confirm Connecticut’s.
Connecticut has 7 brackets from 2% to 6.99%; the top rate starts at $500,000 for a single filer and $1,000,000 for a married couple filing jointly; no state standard deduction is applied; the personal exemption is $15,000 single and $24,000 joint. Connecticut’s personal exemption phases out above $30,000 single ($48,000 joint); the calculator applies the phase-out.
