Why 1099k for me?

[SteveHuss]

I use Paypal's personal account to receive some reimbursements (not for income), that are under 5k USD and less than 100 transactions. Paypal has issued me a 1099k, although the threshold to issue 1099k is 20k USD and at least 200 transactions.
1- Why am I issues 1099k
2-Is it necessary for me to include it in my tax returns even though I am well below the threshold?

I have only 1800 $ and less than 50 transactions and they still sent me 1099 k, I also got the reimbursements or gifts from friends and family. Looking for answers just like you.

Do you live in any of the states with lower reporting thresholds? Like VA, MA, VT?

If so, you got the form because your sales exceeded the state's reporting threshold

I am in IL but these are not sales, it's not a business account. These are rebates and reimbursements for trying and reviewing products.
