2018 Tax Law Changes

For tax years beginning after December 31, 2016 and before January 1, 2019, medical expenses, for all taxpayers, are deductible to the extent that they exceed 7.5% of AGI.

In addition, the AMT preference related to medical expenses is eliminated.

Personal casualty losses occurring in a tax year beginning after December 31, 2017 but before January 1, 2026 are not deductible, unless the loss is incurred as a result of a federally-declared disaster.

For contributions made in tax years beginning after December 31, 2017 and before January 1, 2026 the 50% limitation is increased to 60%. Any amounts in excess of the new limit can be carried forward and deducted for up to five years (as was allowed under prior law).

For any contribution made in a tax year beginning after December 31, 2016, the requirement of a charity to provide contemporaneous written acknowledgement as substantiation for any contribution of $250 or more is repealed.

Beginning in 2018, no charitable deduction is allowed for any payment to an institution of higher learning in exchange for which the contributor is given a right to purchase seats at an athletic event.

Prior to the enactment of the new law, charitable contributions were deductible with certain ceilings based upon a percentage of AGI. A 50% of AGI limit applied to cash contributions to public charities and certain private foundations.

The combination of residential property taxes and Income or sales taxes is capped at $10,000.

Property taxes remain fully deductible for taxpayers in a business or for-profit activity, so taxes paid on rental realty can be taken in full on Schedule E.

Pursuant to the Act, for tax years beginning after December 31, 2017 and before January 1, 2026, a deduction will only be allowed for interest on a debt that qualifies as Acquisition Indebtedness. No deduction will be allowed for Home Equity debt.

In addition, the Act reduces the amount of eligible Acquisition Indebtedness borrowing to $750,000 for any debt incurred on or after December 15, 2017.

A taxpayer who entered into a binding contract before December 15, 2017 to close on the purchase of a residence before January 1, 2018, and who actually closes on the acquisition before April 1, 2018, shall be considered to have incurred the Acquisition Indebtedness before December 15, 2017.

ii. The old Acquisition Indebtedness limits continue to apply to taxpayers who refinance existing Acquisition Indebtedness as long as the indebtedness resulting from the refinancing does not exceed the amount of the original debt.

For 2017, the deduction for Qualified Residence Interest was limited to interest paid on up to $1,000,000 of borrowing that qualified as “Acquisition Indebtedness” and up to $100,000 of borrowing that qualifies as “Home Equity Indebtedness”.
Acquisition Indebtedness being defined as debt incurred to acquire, construct or substantially improve a principal residence or a second home, with no restriction on the use of Home Equity Indebtedness.

For tax years beginning after December 31, 2017 and before January 1, 2026 all miscellaneous itemized deductions that were previously subject to a 2% AGI limitation are suspended.

Among the items included in this elimination are:
All unreimbursed employee business expenses;
Union dues
Brokerage fees
All expenses related to tax return preparation;
Appraisal fees for charitable contributions;
Investment expenses.

For tax years beginning after December 31, 2017 and before January 1, 2026, the overall itemized deduction limitation of 3% of the excess of AGI over the threshold amount (applicable to certain itemized deductions) is suspended.

For tax years 2018 through 2025 the deduction for personal and dependency exemptions is effectively suspended by the Act reducing those amounts to zero.

The Act increases the base standard deduction from the inflation adjusted levels that applied in 2017 to:

$12,000 for Single, Qualifying widower and Married filing separately taxpayers.

$24,000 for married taxpayers filing Joint returns,

$18,000 for taxpayers filing as Head of Household.

The additional standard deduction available to taxpayers who are age 65 or older and or blind remain unchanged.
For 2018 the additional amount is $1,300 for married taxpayers and $1,600 for unmarried taxpayers.
