An overview of the new tax law

The Tax Reform Act of 2018 has limited the amount a taxpayer can deduct as itemized deductions on the federal tax return. Married couples are allowed up to $24,000 in itemized deductions. Taxpayers who have a filing status of single are allowed up to $12,000. 

The state and local tax deduction (SALT) has historically been the largest or second largest deduction claimed on Schedule A. The next itemized deduction that comes in either first or second place, depending on the size of the mortgage outstanding, was historically the mortgage interest deduction. Other popular itemized deductions on Schedule A were as follows: medical expenses which had to exceed the 7.5% or 10% AGI threshold before providing a financial benefit, charitable contributions subject to other thresholds and lastly what is commonly referred to as “other deductions” that had to exceed the 2% AGI floor.

Prior to this newly enacted tax law, a taxpayer who itemized deductions and was not subject to an alternative minimum tax (AMT) was allowed to deduct the state taxes & real estate taxes incurred and paid throughout the year on Schedule A. Assuming a taxpayer was not subject to AMT, if the resident state (or states that had nexus) imposed a high state tax rate and the taxpayer generated a reasonably high taxable income she or he would obtain a sizable tax benefit on their federal income tax return. In other words, if a couple generated say $300,000 in taxable income and was subject to a 6% state tax rate the couple was able to deduct $18,000 in state taxes on their federal return. If their real estate taxes were $20,000 they would receive a total benefit of $38,000 ($20,000 plus $18,000) in SALT deductions on Schedule A.

With this newly enacted tax law, Congress limited the SALT deduction to $10,000. Said differently $28,000 ($38,000 less $10,000) of former tax deductions that were available to the taxpayer is no longer available as a tax deduction for all future years. If the couple was in the 30% federal tax bracket, the taxpayers would have to pay an additional $8,400 in federal taxes going forward.

It is worthy to note, the $10,000 SALT limitation may be even further limited (depending on how you look at it) based on the $24,000 total itemized deduction available. In other words, if the mortgage interest exceeded $14,000 then either the mortgage interest or SALT deduction was automatically limited so the total itemized deduction would not exceed $24,000 for a married couple.

On the surface, without further analysis, the new tax law that imposes a SALT deduction appears to favor taxpayers who are not married (or no longer married) and who do not have large SALT or mortgage interest deductions.

How does this new tax law impact parties going through a divorce?

When it comes to a divorce these issues have to be closely analyzed to optimize the tax code for the divorcing party’s benefit. In context to a divorce and this new tax law, some questions that arise are:

  1. How will each spouse’s tax liability be impacted as a result of the separation?
  2. Would one or both parties benefit tax-wise moving to another state? If so, which state is the best state to live in and why? 
  3. Would nexus come into play if one or both parties moved?
  4. If multiple properties exist in a portfolio, how should the real estate be divided to optimize the real estate tax deduction available? 
  5. Are there ways to legally take deductions on one or both taxpayers returns to optimize the available SALT deduction? 
  6. What other ways exist to design the financial settlement structure to optimize the SALT deduction?

This new tax law will have a meaningful impact on future tax liabilities of divorcing parties.
