Project ID Number:
(Found on your project page, under the title.)

Extra Payment Amount: $
Note: This is the amount you were paid ABOVE your original bid.
These are some common scenarios:
-Your bid was $200, but you were paid $300 instead, then you would enter "100" here.
-Your bid was $50, but you received $200, then you would enter "100" here (you only need to report earnings received over $100).
-Your bid was $20, but you received $75, you do not need to report extra earnings (since the total amount received was under $100).
If you were paid in increments and already reported some of the extra payment, then you only need to enter the unreported amount.
For featured projects, if your total payments are greater than $2500, than all payments received over $2500 need to be reported.
