No you don’t. I run my own affiliate marketing business. I did not have to get any type of licence. Save all your reciepts for your internet bills, printer, paper etc. etc. The companies will send you tax information for the year (W9’s), and when you file your taxes, you can use your reciepts for tax write-offs 
Affiliate Marketing can be simplified if you find the right products to market and also have learned how to market them in the right ways but how to learn to be an marketer and what if you want to just do an Ecommerce Store? Well I have found a product that helped me earn money online with ecommerce and I am sure it would work for someone else as well and it is called Niche Blueprint 2.0. This is a course filled with material that teaches you how to build these stores and comes with the tools you need for market research, software for the stores themselves and also some tools that you can not find anywhere online, ok you can find them but not for the price that Niche Blueprint comes in at with no monthly fees. So read the Niche Blueprint 2.0 Review here and maybe this year will be your year.

NO – in fact you can pretty much operate as a sole proprietorship. Why hassle yourself with a corporation’s double taxation, difficulty and expense in setting up when you are simply selling other people’s products in your affiliate marketing business?
