Did I make money in other states?

[RemoteWorkerZ]

I live in Colorado, but my company is located in Texas and I telecommute/work remotely. I travel occasionally for work (quarterly) for large business meetings in Texas, otherwise I'm still living and working in CO. 

Did I "make money in other states"? I've seen several questions on the topic, but all I got from this is "it's tricky." Thank you in advance, as it's the first time I've had to deal with this tax situation.

Since Texas does not have a personal income tax you would answer No to the question of making money in other states.

Answer No.  The purpose of that question is to see if you need to file a state tax return for another state. 

Having earned money in another state does not reduce the amount of tax calculated for your home state.

This is the general rule: The income is work state (WS) source income since it was earned there. Resident States (RS) tax all their resident's income, regardless of where earned. You will file a non-resident tax return for the WS and report the WS income. You will file a full year resident return for the RS, reporting all your income. The RS will give you a credit, or partial credit for any tax paid to the WS.  Since your WS (TX) doesn't have a tax, all that is moot.
