IOSS, VAT, and SKULabs

Many countries require a tax ID on international shipments, such as an IOSS number for low-value shipments to the EU, a VAT or EORI number, or a UK HMRC number. SKULabs can send these to the carrier with your labels and customs data. This article explains where to set them.

Your tax IDs (payer / shipper)

SKULabs uses your tax ID in this order:

  1. A tax ID imported with the order from the channel. For example, when Amazon or eBay collects VAT on an order, SKULabs imports the marketplace's IOSS or VAT number as the payer tax ID.

  2. Otherwise, the federal tax ID on your store's origin address. See How do I change my store's origin and return address?

For other tax IDs (IOSS, VAT, EORI, HMRC, VOEC and more), add them under Settings > Shipping > Tax identifiers, then apply them to the right shipments with the shipping rule action Set tax identifier. For example, a rule for orders shipping to EU countries under 150 EUR can set your IOSS number. See Tax Identifiers and How to create and use shipping rules.

Tip: depending on the destination and type of number, the carrier may need a prefix on the tax ID. For example, IOSS numbers may need an "IOSS" prefix, and shipments to the UK may need a "GB" prefix.

Buyer tax IDs

From some channels SKULabs imports the buyer's tax ID automatically. You can also enter or edit the buyer's tax ID when you create or edit an order in SKULabs. Carriers use it to identify who is importing the goods.

Which carriers receive tax IDs

Tax ID support depends on the carrier connection. For details on FedEx and UPS, see How to include federal tax ID on customs documents generated by FedEx and UPS. If your carrier doesn't accept a tax ID you need, contact support.
