Independent Contractor--Where to File State Taxes

Hello,

 

Thank you to all of the helpful members of this community.

 

I live in Kansas and receive a W-2 from a "standard" job in the state. Occasionally, I do some remote consulting work for other organizations. This year that equates to two organizations in two different states:

  • Illinois- $5,000- received 1099-NEC
  • Washington- $600- have not received any tax form

All work was performed remotely in Kansas. 

In which states do I need to file state tax returns? TurboTax indicated I do not need to in Washington due to no income tax, but for Illinois it did not clarify, and says I "might" need to.

 

Could anyone help?

 

Thanks
