The American Tax Cuts and Jobs Acts (TCJA) continues to be the law of the land, and the still comparatively new law will affect your 2019 income tax return. But how has it changed since it went into effect, you ask? It namely affects your estimated tax payments, the money withheld from your paycheck, and your income tax return for 2019.

This means that you need to understand what changes have been made so you can file your 2019 return and make sure you’re paying in enough taxes to avoid getting hit with penalties and interest. Here are some of the major items of note  in this (relatively) new tax law that will likely affect you:

1. Increased Standard Deduction and Elimination of Exemptions

The new tax law has big changes when it comes to the standard deduction and exemptions. Exemptions were eliminated altogether, which can hurt some families substantially. That said, the standard deductions have almost doubled since 2017, which offers some relief. (See the table below for details.)

Filing Status 2017 Standard Deduction 2018 Standard Deduction 2019 Standard Deduction
Single $6,350 $12,000 $12,200
Married filing jointly $12,700 $24,000 $24,400
Married filing separately $6,350 $12,000 $12,200
Head of household $9,350 $18,000 $18,350

Because a personal exemption was worth $4,050 in 2017, single filers with no dependents taking the standard deduction will come out ahead. Where the total deduction would have been $10,400, the new law allows $12,200.

A married couple with no dependents filing the standard deduction will come out ahead, too. In 2017, prior to the tax law’s passing, the standard deduction and two exemptions were worth $20,800, but the 2019 standard deduction is $24,400.

Unfortunately, if you have dependents, the increased standard deduction probably won’t offset the loss of the exemptions you would have been able to claim in 2017. Other changes in the law may help lower your tax burden, though.

The major change that comes with the increased standard deduction is the effect on people who used to itemize deductions.

In the past, you could get both itemized deductions and exemptions, but now you can claim only itemized deductions. In addition, the increased standard deduction means that many people who used to itemize may no longer benefit from itemizing their deductions.

2. Changes in Income Tax Rates and Brackets

The income tax rates and brackets changed with the new tax law. While the brackets are different for each filing status, the rate structure remains the same across all four filing statuses (single, married filing jointly, married filing separately, and head of household). Below is a comparison of the 2017 tax rates and brackets and the 2019 tax rates and brackets for a single person.

2017 Brackets 2017 Rates 2019 Brackets 2019 Rates
$0 to $9,325 10% $0 to $9,700 10%
$9,326 to $37,950 15% $9,701 to $39,475 12%
$37,951 to $91,900 25% $39,476 to $84,200 22%
$91,901 to $191,650 28% $84,201 to $160,725 24%
$191,651 to $416,700 33% $160,726 to $204,100 32%
$416,701 to $418,400 35% $204,101 to $510,300 35%
$418,401 and up 39.6% $510,301 and up 37%

The big takeaway is that tax rates have generally decreased. While people in the 10-percent tax bracket won’t see a reduction in their rate, most everyone else up to the 24-percent tax bracket should see some relief. But if you were in the high end of the old 28-percent tax bracket, you might pay a bit more income tax on the marginal income in the new 32-percent tax bracket.

3. The New Child Tax Credit

The new child tax credit has gone through big changes since the law was introduced. The credit was only $1,000 per qualifying child in 2017 and was nonrefundable if you didn’t owe income tax. The 2018 credit is worth $2,000 per qualifying child and is refundable up to $1,400, even if you don’t owe a penny of taxes. The income limit at which the credit phases out has been increased to $200,000 for single filers and $400,000 for those who are married filing jointly.

This bigger credit and its refundability will help offset some of the loss of the exemptions. But as with any tax scenario, how these changes affect you depends on your personal situation.

4. Changes to Itemized Deductions

5 Ways the New Tax Law Will Affect You. Do you find yourself wondering, "How will the new tax law affect me?" Check out this breakdown of what the new rules mean for you. #tax #personalfinance #moneymatters

Itemized deductions have been significantly changed in 2019. As always, you should itemize your deductions only if the amount will be higher than the standard deduction. With the higher standard deductions in the new tax law, this level is harder to reach. Combined with some of the big changes below, itemizing deductions will probably become much less popular than in the past.

Medical and dental costs actually work out in your favor, as you can deduct expenses that exceed 7.5 percent of your adjusted gross income rather than the old 10 percent threshold, giving you 2.5 percent more to deduct.

State and local taxes are still itemized deductions, but they’re much more limited than in the past.

In previous years, you could deduct state income tax or state sales tax plus property taxes with no caps. In 2019, you’ll be able to deduct only a combined $10,000 of these taxes in your itemized deductions.

The new tax law will also significantly affect your situation if you own a home. How mortgage interest is treated has changed with the TCJA. You’ll no longer be able to deduct interest on home equity debt, and mortgage debt interest will be capped at a mortgage value of $750,000 rather than the previous $1 million limit.

Finally, many employment-related deductions for W-2 wage earners were eliminated by the TCJA — important to note if you were intended to deduct your expenses individually from your taxes.

If you are handling your own return, make sure you work with the product that’s best for your needs — ensure that the tax software you use is best suited for your employment classification, and can handle the breadth of your deductions.

As always, you should consult a tax professional with any concerns about your personal situation, and as a means of getting the most out of your return. Make sure to prepare ahead of time as much as possible to avoid the stress of a last-minute filing.
