If you are talking about tax deferred accounts, as in an IRA or 401K, then unless you can disclaim a portion of the accounts, whenever you take a distribution you will have "income" for tax purposes. So if you withdraw $80K, and pay $20k to each sister and keep $20K for you, you will owe tax on $80K. If oyu effective state and fed tax rate is, lets say, 14%, then if you just "short" your sisters 14%, and send them $17,200 rather than $20K, it comes out fair. Regarding a disclaimer, this bears some more research. It may be that you can disclaim 75% ownership in each account, such that they end up being owned by each of you equally. The only thing "I remember about disclaimers is that it has to be in writing, has to be done within 9 months of date of death and has to be done before you have taken/received any benefit from these accounts before you have taken any money out.
