How To Avoid Being Double Taxed On Your After-Tax IRA Contributions

Posted on

Tax Planning with CoinsThe primary goal of income tax planning is to pay the least amount of tax possible. Good tax planning should include avoiding paying tax on the same income twice. One of the primary sources of mistakenly paying tax twice is after-tax contributions trapped in an IRA.

The Economic Recovery Tax Act of 1981 made deductible IRA contributions available to everyone with earned income. All IRA contributions were pretax until the 1986 Tax Reform Act placed limits on the deduction for high-income workers who were also covered by an employer plan. High-income workers covered by an employer plan were still allowed to make IRA contributions, they just couldn’t deduct the contribution from their tax return. Thus began the comingling of after-tax funds (non-deductible contributions) with pretax funds.

Non-deductible contributions to an IRA are reported on IRS Form 8606. This informs the IRS that certain funds in the IRA have already been taxed. This is the process used to track this information so the funds do not get taxed again when they are withdrawn. Non-deductible IRA contributions are not the only way after-tax funds end up in an IRA. They can also be rolled over from an employer plan. The IRS recently ruled after-tax money in an employer plan can be rolled directly into a Roth IRA. The taxable amount of a withdrawal from an IRA containing both after-tax and pre-tax funds is determined using the pro-rata rule. This pro-rata calculation is also done on Form 8606.

A taxpayer must file Form 8606 each year they contribute after-tax money to an IRA. There is a $50 penalty for failing to file Form 8606 when required but it is in the taxpayer’s interest to file the form. Taxpayers who have been lax in filing the form should file a new 8606 to bring the IRS up to date. The taxpayer should indicate cumulative after-tax IRA funds on line 2 of the Form 8606. Be sure to keep any supporting documentation in case the IRS questions the newly discovered after-tax funds.

After-tax funds remaining in an IRA are passed on to the beneficiary when the owner dies. The after-tax funds are distributed to the beneficiary tax-free using the same pro-rata rule. The only difference for a beneficiary is the rule doesn’t factor in other IRAs that may belong to the beneficiary.

Most IRA beneficiaries aren’t aware of after-tax funds in the IRA and pay tax on their entire withdraw. Always ask about after-tax contributions to an IRA you inherit. You may need to talk to the deceased’s accountant to get this information. IRA custodians are not required to track after-tax funds in an IRA. To claim the tax-free portion of distributions from an inherited IRA, a beneficiary will also have to file Form 8606, just as the IRA owner did.

There is no guidance from the IRS for splitting IRA accounts with after-tax funds in a divorce. The consensus among accountants and attorneys is that the pro-rata rule applies when the IRAs are divided. The topic of an IRA’s after-tax funds could be addressed in the divorce agreement. There is no specific IRS guidance preventing the parties involved from deciding how to allocate after-tax funds in a partial transfer between spouses. After-tax IRA funds could be claimed by the spouse with the higher income. The spouse who is in a lower tax bracket might be willing to relinquish after-tax funds in return for a larger piece of the IRA.

Both spouses will need to file IRS Form 8606 when part or all of an IRA is transferred under a divorce or separation agreement and the transfer involves after-tax funds. This includes Roth IRAs, SEP or SIMPLE IRAs. Both parties must report the increase or decrease in after-tax balances for the applicable account. It would be a good idea to include a statement with Form 8606 explaining the reason for the adjustment. Remember, Form 8606 must be filed with a taxpayer’s tax return every year in which there is a change to the after-tax balance in the IRA – either additional contributions are made, withdrawals are taken, or a divorce settlement calls for an adjustment. Taxpayers should retain copies of Form 8606 among their permanent tax records.

Rick’s Tips:

  • You must track after-tax contributions to an IRA using IRS Form 8606.
  • Check with the deceased’s accountant for after-tax contributions on any IRAs you inherit.
  • After-tax funds in an IRA may be divided among spouses through a divorce agreement. Both parties will need to file Form 8606 with their tax return to document the change.
