In 2022 I did post doc in Washington D.C. while living in D.C. from Jan, 2022 until September 2022. Then moved to UK to start another post doc. Earned post doc stipend from UK university from October until December 2022. I use my parents' address in CA as my permanent address. I spent no time in 2022 living in CA. I have some investment income from Vanguard. Am I correct about the following: I will file 2022 IRS return reporting all 2022 income including that earned in UK. I will file D.C. state income tax return for income earned while living in D.C. I will need to file tax return in UK for the post doc stipend earned in UK. I will report my investment income in my D.C. state tax return. I will receive some tax credit either from IRS or UK for reporting my UK post doc stipend on both returns.
Thank you.
