2018 - Tax Cuts and Jobs Act - Summary of Individual Changes

Individual Income Tax Rates

The individual income tax rates and bracket amounts have been modified for tax years 2018 until they sunset after 2025. The temporary tax rates are outlined here. In addition, the “kiddie tax” is simplified for tax years beginning before 2026 by applying ordinary and capital gains rates applicable to trusts and estates to the net unearned income of a child. The tax treatment of capital gains and qualified dividends remains unchanged.

Alternative Minimum Tax (AMT)

Beginning in 2018, the AMT exemption amounts are $109,400 (imarried filing separately or surviving spouse), $70,300  (single or head of household), and $54,700 (married filing separately). The phaseout thresholds are also temporarily increased after 2017 to $1 million if married filing jointly or surviving spouse and $500,000 for all other individuals. 

Estate & Gift Tax

The exclusion amount for estates of decedents dying between 2018 & 2026 will be doubled to $10 million per individual.  This amount will be indexed for inflation.

Return Filing Thresholds

Tax returns will need to be filed for 2018 once the following thresholds are met:

Single $12,000
Married Filing Separately $0
Married Filing Jointly $24,000
Head of Household $18,000
Qualifying Widow(er) $24,000

Higher amounts apply to those over 65 years of age or if blind.

Tax preparers will have additional due diligence requirements imposed on paid return preparers to ensure that clients qualify for the child and education credits, and head of household status.  This should add time to the preparation of all returns beginning in 2018 (2017 tax filing season).

Child Tax Credit

The child tax credit is expanded to $2,000 per qualifying child with phaseout thresholds of $400,000 (married filing jointly) and $200,000 (others).  There will also be a $500 nonrefundable credit for a dependent who is not a qualifying child.  The additional child tax credit, which is refundable is limited to $1,400 per child whose income does not exceed $2,500.

Passthrough Deduction for Qualified Business Income

A deduction of 20% of domestic qualified business income is available to individuals with passthrough income from a partnership, S corporation or sole proprietorship.
