Import One Stop Shop (IOSS) in Austria 2026 – Efficient EU VAT Handling for Non-EU Sellers

What is the Import One Stop Shop (IOSS)?

The Import One Stop Shop (IOSS) is a cen­tral com­po­nent of the EU VAT reform and has offered busi­ness­es from third coun­tries since July 1, 2021, a sim­pli­fied way to declare and remit VAT on cross-bor­der deliv­er­ies to pri­vate cus­tomers with­in the EU. Espe­cial­ly for online sell­ers ship­ping goods val­ued up to 150 euros to EU cus­tomers, IOSS opens up the pos­si­bil­i­ty to stan­dard­ize process­es and gain legal cer­tain­ty.

Before the intro­duc­tion of IOSS, com­pa­nies often had to car­ry out mul­ti­ple nation­al VAT reg­is­tra­tions and sub­mit local tax returns for ship­ments to var­i­ous EU mem­ber states. This was not only time-con­sum­ing but also error-prone and expen­sive. With IOSS, non-EU busi­ness­es can cen­tral­ly man­age their VAT oblig­a­tions through one EU coun­try. A fis­cal rep­re­sen­ta­tive is required for com­pa­nies based out­side the EU. In Aus­tria, this role can be tak­en on by Heinz Kobled­er – Tax Advi­sors, who spe­cial­ize in sup­port­ing for­eign busi­ness­es with their tax oblig­a­tions.

How does the Import One Stop Shop (IOSS) work in practice?

The IOSS process is rel­a­tive­ly effi­cient: the busi­ness reg­is­ters for IOSS via a rep­re­sen­ta­tive in Aus­tria using Finan­zOn­line. Once reg­is­tra­tion is com­plete, they receive an IOSS num­ber that must be used in all rel­e­vant sales process­es. This num­ber allows cus­toms author­i­ties to cor­rect­ly iden­ti­fy IOSS ship­ments and avoid addi­tion­al import VAT charges for cus­tomers.

IOSS registration and IOSS number

The sell­er col­lects VAT at the time of sale and remits it month­ly through an IOSS dec­la­ra­tion. The Aus­tri­an tax author­i­ty then dis­trib­utes the VAT amounts to the appro­pri­ate mem­ber states.

Monthly IOSS reporting and VAT remittance

This cen­tral­ized sys­tem brings sev­er­al ben­e­fits: end cus­tomers pay no addi­tion­al tax­es or fees upon receipt, which great­ly enhances cus­tomer sat­is­fac­tion. Deliv­ery speed also improves since there are no cus­toms delays due to unpaid duties. For the com­pa­ny, IOSS means less bureau­cra­cy, reduced risk of errors, and bet­ter pre­dictabil­i­ty in cross-bor­der trade.

Obligations, risks and the role of the fiscal representative

How­ev­er, par­tic­i­pat­ing in IOSS also entails oblig­a­tions. Sell­ers must ensure that each shipment’s val­ue does not exceed 150 euros and that excise goods such as alco­hol and tobac­co are exclud­ed from the process. They also need to apply the cor­rect VAT rate for each EU des­ti­na­tion coun­try, which can vary. Month­ly returns must be sub­mit­ted accu­rate­ly and on time, or penal­ties may apply.

Anoth­er key fac­tor is select­ing a qual­i­fied fis­cal rep­re­sen­ta­tive. This rep­re­sen­ta­tive han­dles the reg­is­tra­tion process and is joint­ly liable for prop­er VAT com­pli­ance. Choos­ing an expe­ri­enced and reli­able part­ner is cru­cial. Heinz Kobled­er – Tax Advi­sors offer tai­lored solu­tions for non-EU com­pa­nies, from ini­tial con­sul­ta­tion and reg­is­tra­tion to ongo­ing sup­port and full tax com­pli­ance.

Outlook: the future of the Import One Stop Shop (IOSS)

Look­ing ahead, IOSS is set to become even more impor­tant. The EU plans to intro­duce manda­to­ry VAT lia­bil­i­ty for online mar­ket­places start­ing July 2028, fur­ther sim­pli­fy­ing and reshap­ing the sys­tem. Com­pa­nies should famil­iar­ize them­selves with IOSS and con­sid­er a strate­gic EU part­ner. Heinz Kobled­er – Tax Advi­sors offer the exper­tise, expe­ri­ence, and ded­i­ca­tion to ensure a suc­cess­ful imple­men­ta­tion and long-term com­pli­ance.
