The threshold you are referring to all depends on your other income.
I am also a Vine reviewer. I keep an Excel spreadsheet with all my orders, and I have a running year-to-date total at the top of the sheet, so I always know how much I have ordered. Since Amazon is not withholding any taxes, I have to be mindful of our total annual income, and how much tax we have withheld from other income sources.
If you order Vine items throughout the year, it is important to keep track of the ETV. It can add up fast! It could even put you into a higher tax bracket.
