Worked example
Here is the calculation with sample figures. Change any number in the Connecticut Paycheck Calculator to run your own.
| Gross annual salary | $150,000.00 |
| Pay periods per year | 26 |
| Federal rate (%) | 12% |
| State rate (%) | 5% |
| Gross amount | $5,769.23 |
|---|---|
| Federal tax | $692.31 |
| State tax | $288.46 |
| Social Security and Medicare | $441.35 |

Pre-tax deductions
401(k) contributions, health premiums and HSA contributions taken pre-tax reduce taxable wages, so your real withholding may be lower than this simple estimate.
