Together he and I run a popular website. Currently our only income from the website is from Google ads (AdSense), but that will change soon as we are about to publish an ebook. We hope to make enough money off of the combination of the AdSense income and the ebook sales that we can quit our day jobs and devote ourselves full-time to expanding the website. Since working full-time on the site can be done anywhere in the world, we are considering moving to a tax haven such as the canton of Zug.
My questions for you (which I've been unable to answer for myself through googling) are:
1. For an income consisting entirely of ebook sales and AdSense, would we have to set up a company, or would the income be taxable as personal income (similar to if we were employees of a company)?
The next questions apply if we do have to set up a company:
2. Would it make more sense to start a Sole Proprietorship in one of our names (and let the other person appear to not be working), or to start a Kollektivgesellschaft?
3. Registration costs for a Sole Proprietorship are supposedly 500-2500 CHF, and for a Kollektivgesellschaft they are 2500-5000 CHF. Why do the costs vary so much, and what they would likely be in our case?
3. Do you think we could convince the authorities that our business plan is viable? We know how much we make on AdSense, but before we actually start selling the ebook, we obviously don't know for sure how many sales it will generate.
4. Would we be able to forgo the rent for a 'domicile' and just work from home (i.e. from the apartment we would rent)?
5. Similarly, could we forgo company insurance (which I understand is required for fire, water, operational liability)?
6. We intend to make the comparison of (Danish tax + rent of apartment) vs. (Swiss tax + personal insurance + rent of apartment). Are there any other costs of living in Switzerland that may surprise us? (We do realize that costs of living are even higher than they are here.)
Thank you for reading these questions. I look forward to your reply!
