Do U.S. Expats Need to File Colorado State Taxes?

Did you know you need to file your U.S. federal taxes every single year? Yep, no matter where in the world you live in as a U.S. Citizen or Greencard Holder, you are required to report your worldwide income to the IRS (just see this post to learn more about that).

Now the tricker question is do you still need to file your Colorado State Taxes?  

Are you no longer domiciled in the U.S.? Having a domicile means that you don’t consider yourself to have a permanent home in the states that you will return to if your job contract expires, for example. If you still are domiciled in Colorado, you will most likely need to file a state return every year!

If you’re no longer domiciled in the U.S., then here’s a simple guide to let you know if you still need to continue to file your state taxes as a U.S. Expat:

Did you live in Colorado for any part of the year? 

  • Yes: You will need to file as Part-Year Resident, skip down below
  • No: Continue on

Did you earn any Colorado sourced income during the year? 

  • Yes: File as Non-Resident, skip down below
  • No: You don’t need to file

Points to Keep in Mind

Colorado residents must file a state tax return if they are required to file an income tax return with the IRS, even if they do not have a Colorado tax liability.

Additionally, income earned by an individual while they are not a resident of Colorado or Part-Year Resident will be taxed in Colorado only if it is considered Colorado source income. 

What is Colorado Sourced Income? 

  • Money/income earned while you worked physically in Colorado State (i.e. any income including normal salary from your non-US employer) while on a business trip to Colorado.
  • Or income earned from physical property located in Colorado (i.e. rental income from your old Colorado home). 

Other Colorado Income Sources are listed here.
