To add withholdings to a booking go to the Terms > Offer tab and click "Add Withholdings Group" at the bottom.
The first row will allow you to select who the income tax applies to (Agency or Artist) and who the withholding agent is (Agency, Buyer, or Artist).
You can also select if the withholding tax applies to the artist fee, booking fee, or expenses altogether or independently and if it applies before or after sales tax.
Note: If your commission (Booking Fee) is taken out of the Gross, you must leave the Artist Fee and Booking Fee check on.
Adding Deductions and Surcharges (i.e. Allowances, Soli Taxes, etc)
Many countries allow you to deduct a percentage of the fee before applying the withholding tax. This is often called "Allowance" or "Insurance" (Social Security Insurance).
Some countries also require a surcharge of the withholding amount, often called "Solidarity Tax."
To apply a deduction or allowance, click the three dots at the top right of the withholding box, then click Add Deduction.
To insert a surcharge, click "Add Surcharge" within the withholding tax row.
Saving Withholding Group Settings
If you find yourself using a withholding setting regularly, you can save this preset for future use by clicking "Save Setting" then naming the setting.
To implement the setting to future bookings, click "Load Settings" and a list of your saved presets will pop up.
To manage your Withholding Presets click the cogwheel at the bottom right of the pop-up window.
