If you don't qualify for the survey then it means you didn't complete the survey. Daily
Surveys are based on demographics & if today Advertisers are looking for people with the
ages of 24+ & you are only 18 years old then you will not qualify for it but maybe
tomorrow advertisers will specifically look for people with ages between 15 - 20 & if the
survey matches your profile then you will hopefully qualify for it & complete it & regarding
to the "Tax on Payments" . This is a GPT site where you don't get rich but you do make
little extra money. So you are not getting rich & with that said. You should not
worry about paying taxes on the money you make here.
Thanks :)
