This must be done once you complete your registration and before you place your first bid. If you fail to inform us of your tax exemption within that timeline, you could incur a $25 administrative fee (per lot) applied to your invoice/charged to your card to rectify the issue(s) if done afterwards. TNA does not guarantee that we can update your billing before automated payment charges are issued. In other words, if you fail to provide us your tax number, you may be charged taxes, as this may not be possible to reverse. Once invoices are issued and paid for, TNA cannot issue refunds.
