I had my dad do mine while I was gone. I made him a list of all the W-2s I was getting, including other forms as well. I left him a copy of my prior years tax return, all of my information, like SSN and bank account number (for direct deposit) and the money it cost me to file.
And for your "new question":
You are definitely not throwing your life away by taking one semester off. (But everyone here knows that, right?) Look at it this way: your major is undecided. You could be wasting time and money by taking classes that might not go towards your major. I bet that once you do come back, you're going to have a hell of a lot better idea who you are and what you want out of life.
You are going to learn so much about life, people, being responsible, managing money, yourself...
Travel isn't as widely accepted in the States as it is elsewhere. It might not be the best thing on your resume when asked to "explain any gaps in employment" BUT I've read about this happening on a thread somewhere here and it's happened to myself: during an interview, when my "gap in employment" came up; once I said as simply and humbly as I could that I was traveling, all the interviewer wanted to know about was my trip. Easy interview. And I got the job. And I'm pretty sure the other poster did too. It's definitely going to make you stand out from other candidates for a position.
You're going to come back more focused, if you're not struck by wanderlust
Every time I travel, I always find myself meeting really SMART people. And a lot of them are educated. Like I told you before, I only have an associates degree, so every time I'm abroad, I dream about going back and getting my Bachelor's. I want to be smart too!
Maybe if you start showing your parents how serious you are, and start preparing yourself for this trip (visas, flights, detailed itinerary-doesn't mean you have to follow it), they might ease up a bit.
Conversely, you could look into study abroad programs for next semester to get your feet wet. And it'd be a good way to warm your parents up to the idea of you traveling. But I'm pretty sure you wanna take off-now. Just a thought.
