Educating the client is key ... if they pay you thru a CC (which will issue you a 1099) they do not ALSO need to file a 1099 however if they do (to avoid IRS issues later ) you can report all the income from all the forms (even if it is a duplicate) then simply enter a misc expense to negate the duplicate income reported. Although this is not really the correct way to do this it will keep you from having to deal with an IRS CP2000 later.
Sadly the IRS did not take this situation into consideration in their well intentioned attempt to catch unreported income and now with the new requirement to issue them at only $600 it will cause millions of new taxpayers to deal with the unintentionaled consequense starting in 2022. There needs to be better instructions issued on how to handle this "duplicate income" situation. Until this happens all you can is play defense even it it is not 100% kosher.
