Freelance Forums

I am trying to do some freelance design work and after 3 months of searching, I finally found a publisher who wants me to help them design postcards for their books. Does anyone know if I need to get a business license to do freelance work and if I need to charge sales tax for the work?

PLEASE HELP me if you know the answers because I have been searching for answers all over the internet over the past 2 days and I cannot seem to find a website that really has them.

Help! Help! Help!

There is an upwards limit as to how much you can earn before declaring tax. I think it is $400/Month, but I am not sure on this matter. I am not sure whether the company deducts it, or if you have to declare it. That should give you a ball-park figure though. Please verify that, as I am not sure, and there is no respite or come back on freelancelounge.com for this unverifired info.
