Two other aspects of the federal estate and gift tax system were also made permanent by the act just passed.

First, provisions allowing portability of the $5 million exemption between spouses remain in effect on a permanent basis.

How does this work? In the first instance, the marital deduction remains in place, meaning that spouses can inherit from one another in an unlimited amount (as long as the inheriting spouse is a U.S. citizen).

After the first spouse dies, the surviving or second-to-die spouse can add any unused exclusion of the first-to-die spouse to the surviving spouse’s exclusion. In 2013, this will allow spouses to transfer a total of about $10.5 million free of federal estate or gift tax.

It is important that after the death of the first spouse that the unused exclusion amount is transferred to the surviving spouse as part of the estate proceedings — by timely and properly filing of a federal estate tax return, even if no tax is owed.

The surviving spouse can use that unused exclusion amount plus their own exclusion to make lifetime gifts or pass assets through the estate of the second-to-die spouse. The surviving spouse should strongly consider filing the estate tax return even if the level of wealth does not appear to reach current exclusion levels since it is difficult to predict increases in estate values during the interim years.

As always, families and individuals should seek advice from their personal tax and legal professionals.

Second, the estate and gift tax system will remain “unified.” As noted previously, the $5 million exemption or “unified credit” (with inflation indexing) is applicable to both lifetime gifts and assets passed through an estate after death.

Estate planners should document gifts, maintain a cumulative total and report gifts to the IRS so that there is a record of lifetime gifts at the time of death. The total of taxable lifetime gifts is then deducted from the exclusion amount to determine the unused exclusion remaining available at death.

Remember, lifetime gifts within the annual exclusion amount ($14,000 in 2013) do not count against the lifetime basic exclusion (the $5 million inflation-adjusted amount).

As an example, a couple can give unlimited $28,000 gifts in 2013 to as many different individuals as desired — and these gifts would not count against the lifetime exclusion.

All farm families and individuals should obtain advice for their own personal situations from legal and tax professional retained by them for that purpose.
