In 2005, Austria modified its group taxation regime and now provides an option for crossborder loss-offset. We analyse the combined impact of Austria's new group taxation and lossoffset limitations on cross-border investment decisions of domestic corporations. Monte Carlo simulations in an inter-temporal setting reveal that the impact on foreign real investment induced by the new group taxation is ambiguous. Whereas marginal investment projects with decreasing cash flows tend to benefit from group taxation, innovative projects with initial losses and increasing cash flows may be discriminated against. Investors should consider domestic income and repatriation policy simultaneously before opting for group taxation.
