Innocent Spouse Relief
Innocent Spouse Relief can only occur if you meet the following conditions. One, you filed jointly with your spouse. Two, there is an understated tax on the return that is due to erroneous items of your spouse or former spouse. Three, you can show that when you signed the joint return that you did not know, and had no reason to know, that the understated tax existed. Four, taking into account all the facts and circumstances, it would be unfair to hold you liable for the understated tax.
Understated tax is if the IRS determines that your total tax should be more than the amount that was actually shown on your return. An example of an understated tax is if your spouse had earned $120,000 for his income, but for his tax records, your spouse puts down $100,000 on his tax return. The IRS would deem that you and your spouse would have an understated tax of $20,000 for not filing in properly.
Erroneous items fall under one of the following. One, unreported income is any gross income item received by your spouse or former spouse that is not reported. Two, incorrect deduction, credit, or basis is where there has been any improper deduction, credit or property basis claimed by your spouse or former spouse. If you have any knowledge of the erroneous items, you and your spouse will be jointly liable for the understated tax.
