When you file your 2018 income tax return, you’ll likely find that some big tax law changes affect you. Yes, individual income tax rates have decreased. But the Tax Cuts and Jobs Act (TCJA) has also made significant changes to personal exemptions, standard deductions, and the child credit. And it has limited or eliminated several itemized deductions that have been valuable to many individual taxpayers. The degree to which these changes will affect you depends on whether you have dependents and, if so, how many. It also depends on whether you typically itemize deductions.

No more personal exemptions

For 2017, taxpayers could claim a personal exemption of $4,050 each for themselves, their spouses and any dependents. For families with children and/or other dependents, such as elderly parents, these exemptions could really add up.

For 2018 through 2025, the TCJA suspends personal exemptions. This will substantially increase taxable income for large families. However, enhancements to the standard deduction and child credit, combined with lower tax rates and other changes, might mitigate this increase.

Nearly doubled standard deduction

Taxpayers can choose to itemize certain deductions or take the standard deduction based on their filing status. Itemizing deductions when the total will be larger than the standard deduction saves tax, but it makes filing more complicated.

For 2017, the standard deductions were $6,350 for singles and separate filers, $9,350 for head of household filers, and $12,700 for married couples filing jointly.

The TCJA nearly doubles the standard deductions for 2018 to $12,000 for singles and separate filers, $18,000 for heads of households, and $24,000 for joint filers. For 2019, they’re $12,200, $18,350 and $24,400, respectively. (These amounts will continue to be adjusted for inflation annually through 2025.)

For some taxpayers, the increased standard deduction could compensate for the elimination of the exemptions and perhaps provide some additional tax savings. But for those with many dependents or who itemize deductions, these changes might result in a higher tax bill — depending in part on the extent to which they can benefit from enhancements to the child credit.

Enhanced child credit

Credits can be more powerful than exemptions and deductions because they reduce taxes dollar-for-dollar, rather than just reducing the amount of income subject to tax. For 2018 through 2025, the TCJA doubles the child credit to $2,000 per child under age 17.

The TCJA also makes the child credit available to more families. For 2018 through 2025, the credit doesn’t begin to phase out until adjusted gross income exceeds $400,000 for joint filers or $200,000 for all other filers, compared with the 2017 phaseout thresholds of $110,000 and $75,000, respectively.

The TCJA also includes, for 2018 through 2025, a $500 credit for qualifying dependents other than qualifying children.

Changes to itemized deductions

State and local tax deduction. For 2018 through 2025, your total itemized deduction for all state and local taxes combined — including property tax — is limited to $10,000 ($5,000 if you’re married and filing separately). You still must choose between deducting income and sales tax; you can’t deduct both, even if your total state and local tax deduction wouldn’t exceed $10,000.

Mortgage interest deduction. You generally can claim an itemized deduction for interest on mortgage debt incurred to purchase, build or improve your principal residence and a second residence. Points paid related to your principal residence also may be deductible. For 2018 through 2025, the TCJA reduces the mortgage debt limit from $1 million to $750,000 for debt incurred after Dec. 15, 2017, with some limited exceptions.

Home equity debt interest deduction. Before the TCJA, an itemized deduction could be claimed for interest on up to $100,000 of home equity debt used for any purpose, such as to pay off credit cards (for which interest isn’t deductible). The TCJA effectively limits the home equity interest deduction for 2018 through 2025 to debt that would qualify for the home mortgage interest deduction.

Miscellaneous itemized deductions subject to the 2% floor. This deduction for expenses such as certain professional fees, investment expenses, and unreimbursed employee business expenses is suspended for 2018 through 2025. If you’re an employee and work from home, this includes the home office deduction. (Business owners and the self-employed may still be able to claim a home office deduction against their business or self-employment income.)

Personal casualty and theft loss deduction. For 2018 through 2025, this itemized deduction is suspended except if the loss was due to an event officially declared a disaster by the President.

Be aware that additional rules and limits apply to many of these deductions. The combination of a much larger standard deduction and the reduction or elimination of many itemized deductions means that, even if itemizing has typically benefited you in the past, you might be better off taking the standard deduction when you file your 2018 return.

Maximize your tax savings

These are just some of the TCJA changes that may affect you when you file your 2018 tax return and for the next several years. We can help ensure you claim all of the breaks available to you on your 2018 return and implement TCJA-smart tax-saving strategies for 2019.
