Most people do not know to ask the question how a 179 deduction impacts spousal benefits after a divorce. Let’s talk about this ever so briefly.

In 2018 the tax laws expanded the 179 deduction from $500,000 per year to $1,000,000 per year. This can provide a significant benefit for business owners who are going through a divorce. Let’s place this in context to a case study.

Imagine Mary and John have been married for 15 years. Mary owns a manufacturing business that generates over $10 million in revenue per year. The business is organized as a multi-member LLC (a limited liability company with more than one shareholder) where Mary has a 50% ownership interest in the business. In 2017, before the change in the tax laws, the business was eligible to deduct up to $500,000 of certain equipment that was purchased within any given calendar year. If the business incurred, say, $600,000 in equipment purchases throughout the calendar year, the additional $100,000 ($600,000-$500,000) could not be deducted on the tax return of the business. It had to be depreciated over the useful life of the equipment, assuming the equipment was not eligible for something special called bonus depreciation. The $100,000 may equate to an annual depreciation of ~$14,000 per year (i.e. a 7 year useful life). In other words, the business would not receive a tax benefit for the cash it spent over $500,000. It would receive the tax benefit over a 7 year period of time not immediately.

Let’s bring that 179 deduction into the personal tax return now. Since the business is organized as a multi-member LLC Mary would receive a K-1 from the business. The 179 deduction would be separately stated on her K-1. Assuming there were enough profits reported on the K-1 she would be able to reduce the profits by the amount of the 179 deduction reported through the K-1. The tax preparer would record $250,000 ($500,000 x 50% ownership interest reported on the K-1) on Schedule E. The $250,000 would directly reduce any taxable income reported on Mary and John’s joint tax return. Assuming the couple was in a 30% tax bracket this would translate into ~$75,000 in tax savings for that year. This also assumed they would file a joint tax return for the 2018 tax year.

Now let’s talk about the expanded 179 deduction created through the 2018 Tax Reform Act. The $500,000 179 deduction limitation has now grown to $1,000,000 (i.e. a $500,000 increase). But, let’s talk about this in context to a divorce. Mary and John decide they want to get a divorce. They start and finish their divorce in 2018. The divorce decree stipulates that Mary would keep the business and John would get other assets in the marital estate such as the vacation home, etc. They finalize and sign their divorce decree in 2018. Since they authorized their divorce decree before the end of 2018, they were not eligible to file married filing jointly or married filing separately. In essence, their tax profiles have now been separated. Unless the divorce proceeding is re-opened the terms of their financial settlement is what they will have to live with for the remainder of their lives.

Since they didn’t know what they didn’t know, they perceived the assets in their divorce were distributed in an equitable manner. Yet, as often is the case, there were a number of hidden assets that were not taken into account in their settlement structure. In context to this article we are only focused on the hidden marital asset created from the 179 deduction available to certain business owners. Now back to our story.

Later in life John finds out in 2018 the business incurred large equipment purchases that amounted to $900,000. Yet, during his divorce no one asked the question whether the business purchased any large pieces of equipment during the year. This placed John in a compromised negotiating position. Yet he didn’t know it. He left a lot of money off of the negotiating table. Let’s see what happened to his future wealth position as a result.

In 2019 John sees Mary driving a beautiful new car. She also moved into a much larger home and started to travel extensively too. He wondered to himself how could this be possible. He knew how much she made in terms of income. He also knew how the assets were divided according to their divorce decree. He said to himself that he could not afford to do what she was doing. So, how could this be possible?

Mary filed her tax return as a head of household. The tax benefit Mary received from the 179 deduction was not addressed in their divorce decree. This 179 deduction created a hidden asset on the marital estate that needed to be addressed in the settlement structure. In the case of Mary and John they never talked about who gets the tax benefit for the 179 deduction. How much did Mary benefit by not bringing this up in her negotiations? Let’s do the math.

The total amount of equipment the business purchased throughout the year was $900,000. She owned a 50% equity interest in the business. $900,000 x 50% = $450,000. This was the amount of the deduction that flowed through to her personal tax return. Since her share of the profits were higher than this amount she was able to deduct the full $450,000 on her tax return. This translated into $450,000 x 30% = $150,000 in tax savings on her personal return. In other words she didn’t have to pay the government that money. She could keep it for herself to use any way she wanted to as her discretionary earnings. John never benefited from that deduction and therefore lost at least $75,000 ($150,000 x 50%) in that silent negotiation.

The 179 deduction is one of many assets that hide in marital estates. These hidden assets are often not discussed during negotiations providing one spouse a benefit and the other one to lose that financial benefit. We call this hidden wealth-at-risk. Divorces involve a lot of hidden wealth-at-risk. It appears in many forms. Yet, it is often not discussed or managed during a divorce process.
