Intertemporal Income Shifting and the Danish 2010 Tax Reform

Forskningsenhed: EPRU


Abstract:
In practice, decisions to change the tax system will almost always create unintended incentives for, socalled, intertemporal income shifting where tax payers earn some income in one year but report this income to the tax authorities in another year (legally or illegally). This was also the case for the recent Danish tax reform, which created large tax incentives to postpone wage payments from the end of 2009 to the beginning of 2010 and to move pension contributions forward to 2009. The main purpose of this project is to investigate the extent to which people use their employer to postpone the payment of their earnings to after the implementation of the 2010 tax reform, where the highest marginal tax rate on earned income was reduced from 59,0 to 51,5 percent (skatteloftet).
