NUA and 10-year averaging tax breaks also apply to beneficiaries (if decedent would have qualified, had he lived to take advantage of them).

IRA beneficiaries are generally unaware of the special tax breaks they are entitled to. As a result, they rarely take advantage of them and tend to overpay their taxes. Professional tax preparers miss these items, too, because they are either so buried with work during tax season when these beneficiaries often have their returns prepared, or because theydon’t think to ask about these little known items.

This is a big break for beneficiaries claiming the deduction. It is valuable to the beneficiary because it is usually about a 40% tax deduction (it will likely be less for beneficiaries who inherit in 2011 or later years since the federal estate tax exemption is larger. But the estate tax rate increased to 40% for 2013 and later years.) That’s 40% of the amount of the IRA withdrawal. If the beneficiary withdraws $100,000 from the inherited IRA, he could be entitled to a $40,000 tax deduction (40% of the $100,000 IRA withdrawal).

The deduction is claimed on the beneficiary’s personal tax return as a miscellaneous itemized deduction. It is not subject to the 2% adjusted gross income limitation and is not subject to alternative minimum tax. However, it is subject to the overall 3% itemized deduction limitation which is effective in 2013 and later years.

If the person who owned the IRA had basis, the beneficiary inherits that basis in the IRA. In an IRA, making nondeductible IRA contributions creates basis. When basis is withdrawn, there is no tax because no deduction was ever taken. But most beneficiaries do not even know to ask. To find out, a beneficiary will have to know if the person they inherited from ever made any nondeductible IRA contributions. They can discover that by looking for Form 8606 (Nondeductible IRAs) attached to any of the deceased IRA owner’s income tax returns. Form 8606 shows the basis (the amount of nondeductible IRA contributions made).

If there is basis, then as the beneficiary withdraws from the inherited IRA, that portion of the withdrawal that is a return of the basis is tax free, the same as it would have been for the person it was inherited from. It is rare that even a professional tax preparer thinks to ask if there were any nondeductible IRA contributions made by the deceased IRA owner.

If no Form 8606 is found, it does not automatically mean that no nondeductible IRA contributions were made. It may mean that the form was never filed. You can still find any nondeductible contributions by checking IRA statements to see when contributions were made. You may also be able to track down Form 5498 for prior years, which would also show if IRA contributions were made. Then you look at the tax return for the year of the contribution to see if a deduction was claimed for that IRA contribution. If not, then you can assume that a nondeductible contribution was made. Keep any documentation after the return is filed in case IRS asks you to show how you came up with the amountof nondeductible contributions. Nondeductible IRA contributions began in 1987, so do not bother checking returns for prior years.

For example, to qualify for 10-year averaging a plan participant must have been born before 1936. But if clients inherit from someone born before 1936 who would have qualified for 10-year averaging, then they also qualify, regardless of their age. The same is true if they want to take advantage of the NUA break. If there was company stock inthe plan, a beneficiary only pays tax on the cost of the stock when it is withdrawn in a lump-sum distribution. The difference between the cost and the current value of the stock when you withdraw it (the NUA) will not be taxed until you sell that stock. When a beneficiary sells the stock, they only pay capital gains tax rates at the current rates. The NUA is a big tax saver when stock has greatly appreciated since it was purchased in the plan.

As of 2010, plans must allow all non-spouse beneficiaries to do a direct rollover of the inherited plan funds to a properly titled inherited IRA or inherited Roth IRA. Non-spouse plan beneficiaries can lighten the tax burden of a distribution or conversion to an inherited Roth IRA by taking advantage of the NUA and 10-year averaging tax provisions that are available for qualifying lump-sum distributions (as long as the plan participant would have qualified).

There is also a special tax break if any of the lump-sum distribution is from plan participation before 1974. The provision is known as the “Capital Gain Election,” but the tax rate on the pre-1974 amount stays at 20%.
