do you have to pay taxes on money earned from surveys or mylot?

Well if you're from the US: http://www.IRS.gov should answer all of your questions. I think if it's the only income that you're making then it's somewhere around the $500-$600+ in a given calender year when you have to pay taxes on it. If it's something you do in your spare time away from your main job my guess is that you just report it as "misc income" or something like that. I forgot what exactly it is called(That might be it for all I know!). If you depend solely on the income then you would be considered self-employed and an independent contracter. Those are the sections you should be looking under if you relie solely on these kinds of sites for income(Some do and it is definitely possible if you build up a big enough downline or sell products online..affiliate marketing). Hope this helps.

It differs from country to country. I know in Holland you can make up to 400 euros a month without having to pax taxes, but you are obligated to let the government know that you have earned it. It's a taxfree limit and a lot of countries have them, but the rate is different and also whether or not you need to fill out a form for them.

It's different from country to country and it depends a lot on how much you earn.
