Reference guide on the major issues and how the TCJA impacts them

ACA individual mandate penalty – The TCJA permanently repeals the penalty for failure to obtain minimum essential health coverage, starting in 2019.

Alimony payments– The TCJA permanently eliminates deductions for alimony payments required by post 2018 divorce agreements and the requirement that individuals must report alimony payments as taxable income.

Alternative Minimum Tax
– The AMT is sticking around for individuals. The exemption amount and the exemption phase out thresholds have been raised. Check out our recent blog for more on this: Tax Reform FAQs: Is the AMT Repealed? .

Capital gains and qualified dividend rates-
The TCJA retains the prior maximum rates on net long term capital gains and qualified dividends, as well as the 3.8% net investment income tax (NIIT) for higher income earners.

Charitable contributions– Income based limits for individuals have increased from 50% to 60%. There is concern that larger standard deductions may remove the tax incentive to donate to charity.

Dependent exemption– The TCJA suspends this deduction.
Discharges for student loan debt- The rules have been modified to allow for the exclusion of student loan debt from income on account of death or disability.

Family and medical leave– The TCJA introduces a new credit (available only in 2018 and 2019) to motivate employers to offer up to 12 weeks of paid family and medical leave for eligible employees.

Federal estate tax– The TCJA increases the unified estate and gift tax exemption from $5 million to $10 million (indexed every year for inflation). This year the exemption, indexed for inflation, is $11.18 million (or $22.36 million for married filing jointly)

What about the GST? The generation skipping transfer tax exemption has been increased to the same amount as the unified estate and gift tax exemption. For more, read How does Tax Reform Impact Estate Planning?

Gambling related expense deductions– This TCJA adds limitations to this deduction—You can now only deduct losses up to the amount of your winnings. Any excess loss cannot offset other highly taxed income. Thus, those in the trade or business of gambling, may no longer deduct non-wagering expenses, such as travel expenses or fees, to the extent those expenses exceed gambling gains.

Hobby loss deductions– The TCJA suspends itemized deductions for hobby-related expenses.

Home equity loans– The TCJA suspends the deduction for interest paid on home equity debt, unless the proceeds are used to buy, build or substantially improve the primary residence secured by the debt.

Itemized deduction– There is no longer a tax benefit for itemizing deductions for many people since the standard deduction has been increased. The itemized deduction phaseout rule for high-income taxpayers has been suspended. Check out our blog, The New Tax Law and its Impact on Itemized Deductions for more.

Kiddie tax– These rules have been simplified by the TCJA. Earned income will now be taxed based on rates for single taxpayers and unearned income above the annual threshold will be taxed based on rates for trusts and estates.

Like kind exchanges– The TCJA eliminates favorable treatment under Section 1031 for exchanges of personal property. Real property exchanges still get favorable treatment.

Loan balances for former employees– Departing employees with outstanding 401(k) loan balances are now allowed until their tax return filing due date to repay them (or contribute the outstanding balance to an IRA or qualified retirement plan) to avoid taxes and penalties.

Medical expense deduction– The AGI (adjusted gross income) threshold for itemized medical expense deductions (previously 10%) has been reduced to 7.5%.
