We recently moved to United States from Canada due to work and my U.S. employer is offering a 401(k) plan. I have a Canadian RRSP that I contributed to but I have no idea how 401(k) plan can help me? What is the difference between 401(k) and RRSP?
Both the 401k and the Canadian RRSP provide monetary savings for retirement.
