I live in Florida permanently and I am financially independent of my
parents.  I worked in Maryland as a full-time, seasonal employee this
summer while residing with my parents in their permanent home in
Maryland.  My company has corporate headquarters in El Paso, TX and
regional headquarters in Alexandria, VA.  Our payroll company is
located in Baltimore, MD.  The company routinely hires professionals
that work with our clients in MD from their homes in other states.

All of my paychecks, benefits, etc. have my Florida address, but I
believe that my earnings are still subject to Maryland state income
tax since the work I did occurred in Maryland.

Payment will be given for finding a loophole for me that is legal and
documented in Maryland tax codes that will allow me to avoid paying
Maryland income tax on the money I earned this summer.

Thank you.

hi realitor,

just a free comment from the peanut gallery.

you might get some useful info from a commenter who happens to know
the answer to this question, but i'm pretty confident you won't get a
nibble from a researcher.  you've set up you question so that, if a
researcher takes the time to thorougly research your question, and
discovers that you DO have to pay the tax in MD, they're out of luck. 
talk about killing the messenger.  i could be wrong, but i doubt many
researchers will want to take that risk.

take it for whatever you think it's worth, but it seems to me you'll
have better luck if you clarify this and say you'll pay for a well
researched positive or negative answer.

You earned it in Maryland; you have to pay Maryland tax.

Thank you barneca, I do appreciate your comment and I recognize your
point.  However I believe that the researcher I'm seeking would be
someone already well-versed enough in MD tax code to know these
loopholes.  I have searched high and low and have had little luck
finding any myself, so I was actually intending to do as you warned
and weed out researchers who may waste time coming to the same
conclusion I have.

daniel2d, 

Could you please be more specific if you are going to comment? 
Consider this: I have a coworker that works in Texas.  He works on a
government contract with a government agency in Maryland. 
Occasionally he travels to Maryland to do work with the Maryland
client on the contract based in Maryland, yet he doesn't pay Maryland
taxes.  In some sense his income is as much derived from the state of
Maryland as mine.  What's the difference?
