Hi, I am a foreign investor, interested to buy some mlp (master limited partnership) units through a broker. I know that a distribution tax is withheld. Filing US taxes is difficult for a foreigner since no tax software is set up to handle both 1040NR and schedule K-1. Also, I cannot open an online account with the IRS to check my returns, since I don’t have a US phone number for example. My question is, what are the legal consequences if I decide to invest in US mlp’s, but don’t file US federal and state tax returns?
