One of the coolest things about the American tax system is that if you spend 4 hours a day at some kind of conference, convention, workshop, or class that will improve your professional knowledge and skills, you can make your trip tax-deductible.
According to economicpolicyjournal.com, however, if you are learning a new trade or business, you will not be able to deduct it.
Make sure to keep your sign-in information or receipts to prove that you attended your event. If you book your flight within a day or two of the beginning and end of the event, you will be able to deduct it.
The cost of your hotel room during the nights of the event will also be deductible. Even your meals during the event are tax-deductible (although no one else's will be).
If you really play your cards right, you may even convince your company to cover the cost of the entry fee of the convention, so the only thing it will cost you is your time.
Save a few pennies, improve your professional knowledge, make yourself look good to your company, and enjoy a lovely trip all at the same time. Win-win!
