The team is working on collecting this information so that they may send you the 1099 form in February for your tax preparation purposes. For your second question, it's best to write to firstname.lastname@example.org.
@MariaG ... I'm a little concerned that the team is collecting this info. That wording makes it sound like it's some sort of manual process. I would think this is something that would have been automated.
1099 forms are still expected by mid-February. Since this is the first time we've used our automated withholding system to populate these forms, we've made use of the IRS' extension option to ensure everything is displaying correctly before we distribute. However, we're still moving as quickly as possible to deliver accurate 1099s in plenty of time for you to make your own tax preparations.
To be clear, you do not need a 1099 to report your income. Just look at your PayPal payouts from January to December and you have your 2020 income from Udemy. This will be the first year they have issued 1099s and we have reported our income every other year. Just be sure you add it up correctly so there is no significant discrepency with the amount reported to the IRS by Udemy.
