Passage of the SECURE Act, signed into law in December, means major changes to IRAs and retirement plans, as well as some important income tax changes. Most significant is the elimination of the “stretch” IRA in favor of the “10-year rule.” This change alone potentially impacts millions of taxpayers and could result in making many current estate plans irrelevant or outdated. Every tax professional dealing with IRA distribution, required minimum distributions and estate planning, as well as those about to prepare tax returns, needs to understand this new legislation and its implications for estate plans currently in place as well as for estate planning and estate tax planning generally.
