Inherited money can be a complicated process if the money you are inheriting is located in a retirement account. IRAs, 401ks, etc. all have their own specific rules you must follow at the inheritor. The majority of the time, people will contact the custodian and request a check.
This can provide a lot of adverse tax consequences.
Instead of taking a lump sum in the form of a check, inheritors should consider starting and inherited IRA. This type of an account could help you save money on taxes over a longer period of time.
