What You'll See on Your Paystub
A Connecticut worker's paystub includes federal income tax withholding plus state deductions and mandatory leave contributions:
| Deduction | Rate | Notes |
|---|---|---|
| Federal Income Tax | Varies | Based on W-4 and income |
| Social Security | 6.2% | Up to $181,200 wage base |
| Medicare | 1.45% | No wage limit |
| CT State Income Tax | 3% - 6.99% | Progressive based on income |
| CT Paid Leave | 0.5% | Employee contribution |
Connecticut Paid Leave
Connecticut requires contributions to its Paid Leave program:
- Rate: 0.5% of wages (employee-paid)
- No wage cap on contributions
- Provides up to 12 weeks of paid leave for qualifying events
- Benefits include bonding with new child, caring for family, own medical needs
You'll see "CT PL" or "CT Paid Leave" on your paystub. This program is fully funded by employee contributions.
Connecticut Personal Exemptions
Connecticut uses personal exemptions rather than a standard deduction:
| Filing Status | Personal Exemption (2026) |
|---|---|
| Single | $15,000 |
| Married Filing Jointly | $24,000 |
| Head of Household | $19,000 |
Connecticut's personal exemptions phase out for higher-income taxpayers. If your income exceeds certain thresholds, your exemption is reduced or eliminated.
No Local Income Taxes
Connecticut does not allow cities or towns to impose local income taxes. Your state withholding covers all Connecticut income tax obligations.
Fairfield County (NYC Suburbs)
Fairfield County is part of the New York City metro area:

Connecticut-New York Border Workers
Many Fairfield County residents work in New York:

Comparing Take-Home Pay

| New York (outside NYC) | ~5.5% | ~$5,500 |
| New York City | ~9% | ~$9,000 |
