If your account previously has not received any payouts then your tax information may be in a pending state. The payout amount estimation may have to default to a 30% withholding rate if we don’t have a more accurate rate calculated for your account yet.
I understand it can be confusing, but at this time you will need to initiate a payout request to have our system calculate the finalized amount and trigger any tax calculations that may be pending on your account.
There are components of our payout and payment processing that may happen asynchronously, which is why we only provide estimates until you open a payout request where final calculations may be confirmed before the funds are marked as eligible for payout. The finalized breakdown is fully available on the payout page and it suitable for booking records once the payout has been paid. Payout request values may change if adjustments/refunds/etc. are generated during the review period.
If you want to see current line items for transactions on your account, both paid and unpaid, you can use the CSV export tool. It also provides an individual breakdown that you can use to calculate an estimate of payout yourself. You can find the link on your dashboard’s Paymanets page, or you can use this link here: https://itch.io/dashboard/export-purchases
