Online advertising is booming thanks to global digitization. In a number of recent German tax audits, tax inspectors have treated payments as withholding tax-inducing royalties if made by German companies to nonresidents offering online advertising services. According to these auditors, cross-border payments are made for the use of undisclosed know-how. Consequently, the auditors applied the withholding tax regime on these deemed royalties at a rate of up to 18.8%
German tax authorities officially reject recent tax audit trend. Significant impact on the tax position of nonresident companies offering online advertising services in Germany could be avoided.
