The U.S. Treasury and the IRS on Thursday put out new guidance and withholding tables for employers that incorporate changes from the new tax law.
Under those new tables, the Treasury estimates that 90% of people who get a paycheck are likely to see more in take-home pay, as soon as February. Employers will have until Feb. 15 to incorporate the changes in their payroll systems.
But for many taxpayers, they will need to assess whether the new tables really are withholding enough money so that they’re not saddled with a big bill when they file their taxes next year.
The major changes affecting individuals include new tax brackets, (mostly) lower income tax rates, a near-doubling of the standard deduction and the elimination of both personal exemptions as well as many itemized deductions.
The new tables are designed not only to best approximate the change in workers’ tax liability under the new law, but to do so in a way that “delivers benefits as soon as possible to as many people as possible with as little disruption as possible,” a senior Treasury official told reporters.
The IRS is not issuing new Form W-4s … yet. “We’ve constructed the tables so that most people should be accurately withheld if they leave their W-4 in place,” a senior IRS official noted.
The plan is to have new W-4s by 2019. Personal exemptions are a core feature of the current withholding system, but now that they are eliminated, “it’s necessary to build a new approach to withholding, which will take some time,” the senior IRS official said.
In the meantime, he urged filers who have complicated tax situations — i.e., anyone who is not single, childless and holding down just one job — to review the number of allowances they currently take on their W4s once the IRS puts out its new withholding calculator by the end of February.
Such a calculator will ask for anonymous inputs — for example, your income, number of dependents and other pieces of information that help determine whether you might be eligible for various tax breaks.
“We would encourage every taxpayer to run their information through the calculator. Then they can decide what they want to do,” the senior IRS official said.
That’s not bad advice for any year when there are big tax changes but it’s especially critical this year.
Most people fill out their W-4 form when they’re hired at a new job and don’t change it unless they get married, have kids, get divorced or experience other life-changing situations.
And roughly three-quarters of tax filers are overwithheld because they take too few allowances. And that results in a refund when they file their tax returns. The IRS doesn’t expect that to change much under the new tax law given the preference filers have shown for getting big refunds, rather than just breaking even or having to cut a new check to Uncle Sam when they file theirreturns.
Too good to be true?
Democrats are concerned the rushed withholding tables could leave many tax filers in a situation of potentially being underwithheld for tax year 2018 and thereforeleft owing money when they file their tax returns in early 2019.
“Republicans are using brute force and speed to implement a law that will deliver a financial blow to hardworking Americans all across the country,” Sen. Ron Wyden, the top Democrat on the Senate Finance Committee, said in a statement.
Earlier this week, Wyden and Rep. Richard Neal, the top Democrat on the House tax-writing committee, asked the Government Accountability Office to analyze the new IRS tables to see if they might lead to systematic underwithholding of federal taxes from paychecks.
“I look forward to GAO’s independent review of these tables, which will expose whether the Trump administration is tampering with Americans’ paychecks, resulting in a whopping tax bill next year,” Wyden said.
The GAO has said Wyden’s request must go through its usual review process before a decision to proceed is made.
Treasury Secretary Steven Mnuchin at the White House press briefing on Thursday dismissed suspicions that administration is “juicing” the tables as a “ridiculous charge.”
