What to do
- Ask your employer to withhold Connecticut tax. If New York's tax is higher, withhold the difference for New York too (or make estimated payments) to avoid an underpayment penalty.
- File the Connecticut nonresident return first, then claim the credit for taxes paid to another state on your New York resident return.
- Keep a record of the days you work in each state, especially if you sometimes work from home.
Working from home for a Connecticut employer
Connecticut has a "convenience of the employer" rule. Retaliatory rule: applies only to nonresidents whose home state has its own convenience rule (e.g., residents of NY, PA, DE, NE working remotely for CT employers).
Local income taxes
- New York: NYC personal income tax applies to NYC residents only (about 3.078%-3.876%); nonresidents commuting into NYC pay no city income tax. Yonkers: resident surcharge (16.75% of NY state tax) and 0.5% nonresident earnings tax on wages earned in Yonkers. Self-employed in the MTA district pay MCTMT.
Special credit rules
- NY: NY does not credit other states' tax on income NY treats as NY-sourced. Main double-tax risk is for nonresidents working remotely for NY employers (convenience rule) whose home state will not credit NY tax on days physically worked at home. NJ and CT generally allow the credit; other states may not.
Frequently asked questions
Do I pay Connecticut income tax if I live in New York?
Yes. Connecticut taxes wages earned there by nonresidents. On $100,000 that's about $4,975.
Do I have to file taxes in both New York and Connecticut?
Usually yes: a nonresident return in Connecticut and a resident return in New York, where you claim a credit for the tax paid to Connecticut. File the Connecticut return first.
Will I be taxed twice?
Not on the same state-level wages. New York credits the tax you pay Connecticut, so your total is about $4,975 on $100,000, compared with $4,860 if you also worked in New York. Local city or county taxes may still apply.
