Yes, regardless of the form, the income should be
considered for your return. If you are self-employed or a LLC, the income is reportable and you deduct your expenses. If you sold a few personal items (not for a trade or business) and you have a loss (common), you do not need to report the income.
The threshold is for the companies issuing the forms, but not for you to report the amount. If you are required (or choose) to file a return (based on exceeding minimum income thresholds), then you must report
all income.
The 1099-Ks are a requirement for the payment processing companies - to - the IRS/MA state. They simply include a copy to you. You are required to account for this income, regardless of if you get a form or not.
You do not enter form 1099-k on your return.
In other words, you don't need to be concerned with if these companies are following the rules or not. Let me know if you have any questions.
