Under the pre-Act rules, you could deduct interest on up to a total of $1 million of mortgage debt used to acquire your principal residence and a second home, i.e., acquisition debt. For a married taxpayer filing separately, the limit was $500,000. You could also deduct interest on home equity debt, i.e., debt secured by the qualifying homes. Qualifying home equity debt was limited to the lesser of $100,000 ($50,000 for a married taxpayer filing separately), or the taxpayer’s equity in the home or homes (the excess of the value of the home over the acquisition debt). The funds obtained via a home equity loan did not have to be used to acquire or improve the homes. So you could use home equity debt to pay for education, travel, health care, etc.

Under the TCJA, starting in 2018, the limit on qualifying acquisition debt is reduced to $750,000 ($375,000 for a married taxpayer filing separately). However, for acquisition debt incurred before Dec. 15, 2017, the higher pre-Act limit applies. The higher pre-Act limit also applies to debt arising from refinancing pre-Dec. 15, 2017 acquisition debt, to the extent the debt resulting from the refinancing does not exceed the original debt amount. This means you can refinance up to $1 million of pre-Dec. 15, 2017 acquisition debt in the future and not be subject to the reduced limitation.

And, importantly, starting in 2018, there is no longer a deduction for interest on home equity debt. This applies regardless of when the home equity debt was incurred. Accordingly, if you are considering incurring home equity debt in the future, you should take this factor into consideration. And if you currently have outstanding home equity debt, be prepared to lose the interest deduction for it, starting in 2018. (You will still be able to deduct it on your 2017 tax return, filed in 2018.)

Lastly, both of these changes last for eight years, through 2025. In 2026, the pre-Act rules come back into effect. So beginning in 2026, interest on home equity loans will be deductible again, and the limit on qualifying acquisition debt will be raised back to $1 million ($500,000 for married separate filers).

A 529 plan distribution is tax-free if it is used to pay “qualified higher education expenses” of the beneficiary (student). Before the TCJA made these changes, tuition for elementary or secondary schools wasn’t a “qualified higher education expense,” so students/529 beneficiaries who had to pay such tuition couldn’t receive tax-free 529 plan distributions.

The TCJA provides that qualified higher education expenses now include expenses for tuition in connection with enrollment or attendance at an elementary or secondary public, private, or religious school. Thus, tax-free distributions from 529 plans can now be received by beneficiaries who pay these expenses, effective for distributions from 529 plans after 2017.

There is a limit to how much of a distribution can be taken from a 529 plan for these expenses. The amount of cash distributions from all 529 plans per single beneficiary during any tax year can’t, when combined, include more than $10,000 for elementary school and secondary school tuition incurred during the tax year.

Before Tax Rerfom changes were effective, individuals were permitted to claim the following types of taxes as itemized deductions, even if they were not business related:

Taxpayers could elect to deduct state and local general sales taxes in lieu of the itemized deduction for state and local income taxes.

New SALT Deduction Limits

For tax years 2018 through 2025, new tax reform laws limit deductions for taxes paid by individual taxpayers in the following ways:

 

Current rules

Under the current rules, an individual who pays alimony may deduct an amount equal to the alimony or separate maintenance payments paid during the year as an “above-the-line” deduction. (An “above-the-line” deduction, i.e., a deduction that a taxpayer need not itemize deductions to claim, is more valuable for the taxpayer than an itemized deduction.)

Under current rules, alimony and separate maintenance payments are taxable to the recipient spouse (includible in that spouse’s gross income).

TCJA rules

Under the TCJA rules, there is no deduction for alimony for the payer. Furthermore, alimony is not gross income to the recipient. So for divorces and legal separations that are executed (i.e., that come into legal existence due to a court order) after 2018, the alimony-paying spouse won’t be able to deduct the payments, and the alimony-receiving spouse does not include them in gross income or pay federal income tax on them.

TCJA rules don’t apply to existing divorces and separations. It’s important to emphasize that the current rules continue to apply to already-existing divorces and separations, as well as divorces and separations that are executed before 2019.

Some taxpayers may want the TCJA rules to apply to their existing divorce or separation. Under a special rule, if taxpayers have an existing (pre-2019) divorce or separation decree, and they have that agreement legally modified, then the new rules don’t apply to that modified decree, unless the modification expressly provides that the TCJA rules are to apply. There may be situations where applying the TCJA rules voluntarily is beneficial for the taxpayers, such as a change in the income levels of the alimony payer or the alimony recipient.

Under pre-Act law, the child tax credit was $1,000 per qualifying child, but it was reduced for married couples filing jointly by $50 for every $1,000 (or part of a $1,000) by which their adjusted gross income (AGI) exceeded $110,000. (The threshold was $55,000 for married couples filing separately, and $75,000 for unmarried taxpayers.) To the extent the $1,000-per-child credit exceeded your tax liability, it resulted in a refund up to 15% of your earned income (e.g., wages, or net self-employment income) above $3,000. For taxpayers with three or more qualifying children, the excess of the taxpayer’s social security taxes for the year over the taxpayer’s earned income credit for the year was refundable. In all cases the refund was limited to $1,000 per qualifying child.

Starting in 2018, the TCJA doubles the child tax credit to $2,000 per qualifying child under 17. It also allows a new $500 credit (per dependent) for any of your dependents who are not qualifying children under 17. There is no age limit for the $500 credit, but the tax tests for dependency must be met. Under the Act, the refundable portion of the credit is increased to a maximum of $1,400 per qualifying child. In addition, the earned threshold is decreased to $2,500 (from $3,000 under pre-Act law), which has the potential to result in a larger refund. The $500 credit for dependents other than qualifying children is nonrefundable.

The Act also substantially increases the “phase-out” thresholds for the credit. Starting in 2018, the total credit amount allowed to a married couple filing jointly is reduced by $50 for every $1,000 (or part of a $1,000) by which their AGI exceeds $400,000 (up from the pre-Act threshold of $110,000). The threshold is $200,000 for all other taxpayers. So, if you were previously prohibited from taking the credit because your AGI was too high, you may now be eligible to claim the credit.

In order to claim the credit for a qualifying child, you must include that child’s Social Security number (SSN) on your tax return. Under pre-Act law you could also use an individual taxpayer identification number (ITIN) or adoption taxpayer identification number (ATIN). If a qualifying child does not have an SSN, you will not be able to claim the $2,000 credit, but you can claim the $500 credit for that child using an ITIN or an ATIN. The SSN requirement does not apply for non-qualifying-child dependents, but you must provide an ITIN or ATIN for each dependent for whom you are claiming a $500 credit.

The changes made by the Act should make these credits more valuable and more widely available to many taxpayers.

Before the TCJA, individuals could claim as itemized deductions certain personal casualty losses, not compensated by insurance or otherwise, including losses arising from fire, storm, shipwreck, or other casualty, or from theft. There were two limitations to qualify for a deduction: (1) a loss had to exceed $100, and (2) aggregate losses could be deducted only to the extent they exceeded 10% of adjusted gross income.

Severe cutback. For tax years 2018 through 2025, the personal casualty and theft loss deduction is not available, except for casualty losses incurred in a federally declared disaster area. So a taxpayer who suffers a personal casualty loss from a disaster declared by the President under section 401 of the Robert T. Stafford Disaster Relief and Emergency Assistance Act, still will be able to claim a personal casualty loss as an itemized deduction, subject to the $100-per-casualty and 10%-of-AGI limitations mentioned above. Also, where a taxpayer has personal casualty gains, personal casualty losses can still be offset against those gains, even if the losses aren’t incurred in a federally declared disaster area.

Insurance policy review needed

The casualty loss deduction helped to lessen the financial impact of casualty and theft losses on individuals. Now that the deduction generally will not be allowed, except for federally-declared disasters, you may want to review your homeowner, flood, and auto insurance policies to determine if you need additional protection.

Starting in 2019, the TCJA has eliminated the shared responsibility payment, more commonly known as the “individual mandate,” that penalizes individuals who are not covered by a health care plan that provides at least minimum essential coverage, as outlined in the Affordable Care Act of 2010 (ACA). Since this penalty is only eliminated starting in 2019, you still need to take account of it in making your health care decisions for 2018.

For individuals who do not have the required health coverage in 2018, the minimum annual penalty is $695 per adult and $347.50 for each child under 18. The maximum annual penalty can be substantially higher based on household income. The penalty applies for each month for which the required coverage is not in place, and is based on 1/12 of the annual penalty amount. Certain individuals may be exempt based on household income or other factors.
