New IRS regulations will require payments for services paid via services like Venmo, CashApp to be reported tonthe IRS on Form 1099-K.  So provider recipients will be subject to taxes on those payments. What is less clear is what information will be included in the Form 1099-K.  Some sources indicate that those forms, issued by the payment app, will include the true identity of each payor - so there will be a loss of anonymity for transactions where that is a concern. Still unclear, but probably wise to revert to good old paper cash for payments to providers.

Do you or anyone know what year this will start?  I think i heard this year ???   And how do they know any transfer is for a service.  

Good Qs. Still unanswered, AFAIK.

"... below certain amounts, how to do they know the difference between a 1099 payment and a "this is for my share of the bar tab" payment? "

Stated in Subject!   This is one of the many reasons the government wants to go cashless......

Cash is KING and always will be ,govt too invasive want to know where you spend your money,

Although I do agree to "Cash Is King". To an Extent that can get annoying. Like when it's busy in this business.
