The service
How we handle your state return
Each state has its own rules for residency, income sourcing and credits. We determine which states you need to file in and prepare each return alongside your federal return.
For multi-state situations, we apply credits for taxes paid to other states where available so the same income isn't taxed twice.
- Resident state returns
- Part-year and nonresident state returns
- Multi-state income allocation
- Credits for taxes paid to other states
- Local and city returns where required
- State amendments and notices

The details
Forms, deadlines and common mistakes
What the State Tax Filing process involves, so you know what to expect before you start.
Forms involved
- Resident return
- For the state you lived in for the whole year
- Part-year resident return
- For each state you moved into or out of during the year
- Nonresident return
- For a state where you earned income but did not live
Key deadlines
- Usually April 15
- Most states follow the federal date, but some differ — we check each state you file in
A due date on a weekend or legal holiday moves to the next business day. See all tax deadlines.
Common mistakes we fix
- Filing only in your new state after moving mid-year
- Not claiming a credit for tax paid to another state on the same income
- Assuming remote work is only taxed where you live — some states tax work done for an employer located there
Pricing
Fees depend on how complex your situation is — for example the number of forms, states, accounts or years involved. You get a quote before any work begins, and there is no charge for the first conversation.
