Employee Obligations (Which Returns YOU Must File)
Since New Hampshire has no income tax, you won't face double taxation. However, if you physically work in Connecticut, you may owe Connecticut income tax (2%-6.99%) and need to file a nonresident Connecticut return.
Employer Obligations (What Your Employer Must Withhold & Remit)
Register for withholding and unemployment. Must withhold PFML contributions. Connecticut's COE rule does not apply to Minnesota employees. Unemployment applies to the first $25,000 of wages.
Other Paycheck Deductions (Disability, Paid Leave, Unemployment)
PFML 0.5%.
Remote Work Tax Risk — Convenience of Employer (COE) Rule
Connecticut has a reciprocal COE rule — it only applies to residents of states that also have a COE rule. New Hampshire does not have a COE rule, so Connecticut's rule does NOT apply to you.
