Connecticut runs its withholding through a letter code rather than allowances. Form CT-W4 asks you to pick one of six codes, A to F, based on filing status and, for married couples, whether your spouse works and how much the household earns together. The code decides your exemption, your bracket widths and the personal tax credit built into the calculation, so choosing the wrong letter can swing each paycheck noticeably.
The default is the expensive one. If you never hand in a CT-W4, your employer must withhold under code D, at the state’s top withholding rate with no exemption at all. A new hire who fills in only the federal W-4 lands on this code by default. Code E is for those who expect no Connecticut liability, and the form also lets you add a fixed amount to each paycheck or take a fixed amount off it.
Under the surface, the employer’s calculation is more involved than a plain bracket table. Connecticut takes back the benefit of its lower rates as income rises, through an add-back and a recapture amount, and both the exemption and the personal credit shrink as income climbs until they disappear. That is why the state line climbs faster than salary in the middle and upper ranges. The calculator below follows the Department of Revenue Services’ published withholding rules step by step.
Connecticut employees also pay into CT Paid Leave, which funds paid family and medical leave. It is deducted from wages up to the Social Security wage base, and employees cannot opt out.
Cities and towns in Connecticut do not tax wages. The state has no reciprocal agreements, which matters for the many residents who commute into New York: New York withholds on work done there, and Connecticut counts that tax against its own withholding so the two are not stacked in full. Residents of nearby states who work in Connecticut have Connecticut tax withheld.
How Connecticut taxes your paycheck
State income tax withholding
On the tax return, Connecticut taxes income in brackets, and the rate on the highest bracket is 6.99%. Employers' withholding tables use the same rates, so the highest slice of pay is withheld at 6.99% too. The withholding figures here follow Connecticut's own instructions for employers.
For a single filer paid every two weeks, Connecticut withholds 1.3% of a $30,000 salary and 5.5% of $150,000:
| Salary | Connecticut tax withheld | Share of pay |
|---|---|---|
| $30,000 | $398 | 1.3% |
| $50,000 | $1,800 | 3.6% |
| $75,000 | $3,475 | 4.6% |
| $100,000 | $4,975 | 5.0% |
| $150,000 | $8,226 | 5.5% |
Payroll levies
Besides income tax, one payroll levy comes out of each Connecticut paycheck: $298 a year at the median wage.
- CT Paid Leave (employee): 0.5% of wages up to $184,500 a year. On the median wage that is $298.48 a year.
City and county taxes
No Connecticut city or county withholds income tax from wages, so state income tax and CT Paid Leave (employee) are the only Connecticut lines on your pay stub.
Living in one state and working in another
Connecticut has no reciprocal agreements, so it withholds from everyone who works there, wherever they live. If you live elsewhere, your home state may withhold too, usually less a credit for the Connecticut tax.
Enter both states in the calculator to see the credit at work; the guide to reciprocity agreements lists every pair of states that has one.
