Hello, I am a US resident and have a regular W2 job. To qualify for the STR loophole, can my STR be in any country around the world? Or does the STR have to be in the USA? Any other considerations I should be aware of?

Hello, I have $7800 in my 401K. I quit my job this year and am considering transferring my 401K to an IRA. Am I able to move it to a traditional IRA, and then convert it to a Roth IRA (I.e. backdoor roth IRA)? Or does the backdoor roth IRA not work for 401K conversions?

Hello, my husband and I currently live in New York and I am wondering how to change my tax residency to Florida to reduce my taxes. We are renters in New York and both work remotely. We have a property in Florida which we use as an STR. What's the minimum amount of time we need to spend in Florida in order for Florida to be considered our primary state of residence for tax purposes?
