There are lots of sites on the internet offering online survey opportunities
that claim to pay cash, give prizes, let you earn points to get incentives, offer product testing, etc. It can be a great way to bring in some extra cash or get free gifts but these are not all legitimate sites.
Some turn out to be just a listing of other survey sites. Some require payment for you to see their lists (never pay to get URLs for
survey sites...use a free
search engine to find them yourself).
I recommend that you don't join a survey site that isn't located in the US.
That way if you ever encounter a legal problem with them, you would have better luck settling it if the site is governed by US laws.
Companies that ask you to complete offers as surveys: That's up
to the individual whether they like to sign up for offers to get freebies,
GCs, or whatever the offer may be. Sometimes you have to sign up
for several things in order to qualify for the freebie or GC.
Be careful and do your research before you join any. Here's a link to a very
helpful site where you can read reviews of just about every survey site and you can post your ratings of sites www.surveypolice.com/
Currently US Tax Law allows you to earn up to $600 annually
from any one company and you don't have to claim it on your income tax.
So monitor your earnings from each survey company you are registered with
in order to avoid paying taxes on the earnings.
And, in case you are wondering, yes, I do surveys. But I always check the company out before signing up. Hope this information is helpful to you.
