Did you withhold enough money from your regular paychecks in 2018? If you withheld too little — or, didn’t pay enough estimated taxes if you’re self-employed — you could have an unpleasant surprise when you file your 2018 return.

Tax Law Changes

The Tax Cuts and Jobs Act (TCJA) has made several significant changes to the tax rules for individuals for 2018 through 2025. As a result, many taxpayers who previously itemized deductions are expected to claim the standard deduction, starting in 2018.

Specifically, the TCJA:

  • Almost doubles the standard deduction to $12,000 for single filers, $24,000 for joint filers, and $18,000 for heads of households.
  • Limits the itemized deduction for state and local taxes combined to $10,000 per year. This applies to any combination of 1) state and local property tax, and 2) state and local income tax (or state and local general sales taxes if you chose to deduct them instead of state and local income taxes). Previously, these amounts were fully deductible by most taxpayers who itemized deductions.
  • Potentially reduces the itemized deduction for mortgage interest. The interest deduction for new acquisition debt is limited to interest paid on the first $750,000 of debt, down from $1 million. (Pre-TCJA home acquisition debts of up to $1 million are grandfathered under prior law.) In addition, the deduction for interest paid on up to $100,000 of home equity debt is generally repealed (unless the home equity debt is used to buy, build or substantially improve the home secured by the debt, in which case it can be treated as acquisition debt subject to the $750,000 limit).
  • Eliminates itemized deductions for most miscellaneous expenses, such as investment advisory fees and unreimbursed employee business expenses.
  • Eliminates personal and dependent exemption deductions.
  • Increases the child tax credit — which generally applies to dependent children under age 17 — to $2,000, and the income phase-out thresholds to $200,000 for singles and heads of households and $400,000 for married couples who file jointly. So, many more households will be eligible for the increased credit.
  • Introduces a new $500 credit for other qualified dependents, including a qualifying 17- or 18-year-old, a full-time student under age 24, a disabled child of any age, and other qualifying (nonchild) relatives if all the requirements are met.
    Withholding Basics

Employers are required to withhold taxes from the paychecks of employees. Likewise, self-employed individuals and retirees and others with investment income or retirement account withdrawals must make quarterly estimated payments.

If you fail to comply with the requirements, you could be liable for an estimated tax underpayment penalty, in addition to the tax liability.

The due dates for the quarterly estimated payments for a tax year are:

  • April 15,
  • June 15,
  • September 15, and
  • January 15 of the following year.

These dates are adjusted for weekends and holidays.

Safe Harbors

You can avoid an estimated tax underpayment penalty using any one of these three safe harbor rules:

  1. You pay at least 90% of the current year’s tax liability. This requires you to make a calculated guess of your current tax situation.
  2. You pay at least 100% of the prior year’s tax liability. (Or you pay at least 110% of the prior year’s tax liability if your adjusted gross income for the prior year exceeded $150,000.) This safe harbor is usually the easiest one to use because you know the exact amount of your previous tax liability.
  3. You pay at least 90% of the current year’s “annualized income.” The annualization method often works well for certain individuals, such as independent contractors, who receive most of their income on a seasonal basis.

Possible Relief?

Senator Ron Wyden (D-OR) recently queried the IRS about possible penalty relief for underwithholding due to changes in the TCJA. Wyden cited a Government Accountability Office report that estimated that nearly 30 million taxpayers could be underwithheld in 2018. Although the IRS recommended throughout 2018 that taxpayers check their withholding, few actually went through the steps required on the IRS website to ensure they had paid in enough to fall within the IRS safe harbors.

Separately, the American Institute of CPAs (AICPA) and the National Conference of CPA Practitioners have asked the IRS to refrain from imposing underpayment and underwithholding penalties on taxpayers due to the TCJA. The AICPA specifically requested relief for taxpayers who are subject to the complex provisions of Section 965, which requires certain domestic shareholders to pay a transition tax on the untaxed foreign earnings of certain foreign corporations.

It’s unknown at this time whether these actions will result in any penalty relief for affected taxpayers.
