Both traditional IRAs and Roth IRAs offer some benefits when it comes to taxes and estate planning, but a Roth IRA comes with one benefit the traditional retirement account doesn't. Both plans let you put money away for retirement while reducing your tax burden, and you can use them both to pass some assets on to heirs without going through probate.
Can you avoid the probate process?
Probate processes can be time consuming and expensive, especially when a dispute arises about a will. Probate is also a matter of public record, which isn't something everyone wants -- you might want to keep some information about your assets and your heirs out of the record, and you can do that. While you can't always avoid probate completely -- your estate itself will likely undergo the process -- you can keep certain assets out of probate.
