The Internal Revenue Service’s targeting of conservative political groups has little if anything to do with most everyday taxpayers, but some lawmakers are hoping attention to the budding scandal will swell public and political support for rewriting and simplifying a federal tax code that has undergone some 5,000 changes in the past dozen years.

“The complexity of the law didn’t require the IRS to target people for their political beliefs,” said Rep. David Camp, the Michigan Republican who chairs the tax-writing House Ways and Means Committee. But, he added, “I think giving the IRS less discretion is going to be important, and that’s what a simplified code would do.”

Most taxpayers now pay someone to do their taxes or buy commercial software to help them file. In a report earlier this year, national taxpayer advocate Nina E. Olson ranked complexity as the most serious problem facing both taxpayers and the IRS. People simply trying to comply with the rules often make inadvertent errors and overpay or underpay, she said. Others, she added, “often find loopholes that enable them to reduce or eliminate their tax liabilities.”

Camp and his Democratic counterpart in the Senate, Finance Committee Chairman Max Baucus of Montana, have been working for months on what would be the first major tax overhaul since 1986. At nearly 4 million words, Camp likes to say the current code is “10 times the size of the Bible with none of the good news.”

Lawmakers in both parties say the current storm buffeting the IRS underscores how overly complex tax provisions have given the agency too much discretion in interpreting and enforcing the law.

“This is the perfect example of why we need tax reform,” said Rep. Tim Griffin, R-Ark., a member of the Ways and Means Committee. “If you want to diminish and limit the power of the IRS, you have got to reduce the complexity of the tax code and take them out of it.”

There are formidable obstacles to completing a major tax overhaul this year or next. Both parties say they want to cut overall tax rates by getting rid of tax breaks but they disagree on whether more revenues should be part of the equation. And for all the work Camp and Baucus have done, they have yet to answer hard questions about which tax breaks to scrap.

Americans like their credits, deductions and exemptions — the provisions that make the tax law so complicated in the first place. In exchange for lower tax rates, would workers be willing to pay taxes on employer-provided health benefits or on contributions to their retirement plans? How would homeowners feel about losing the mortgage interest deduction?

Those are among the three biggest tax breaks in the tax code, according to congressional estimates, together saving taxpayers nearly $300 billion this year.

The IRS scandal erupted a little over two weeks ago when the agency revealed that agents assigned to a special team in Cincinnati had targeted tea party and other conservative groups for additional, often burdensome scrutiny when they applied for tax-exempt status. The targeting lasted more than 18 months during the 2010 and 2012 election campaigns, hindering the groups’ ability to raise money, according to a report by the agency’s inspector general.

Since then, two top IRS have officials lost their jobs, and a third has been placed on paid administrative leave. Investigations by Congress and the Justice Department are under way.

The IRS was screening the groups’ applications because agents were trying to determine their level of political activity. IRS regulations say tax-exempt social welfare organizations may engage in some political activity but the activity may not be their primary mission. It is a vague standard that agents struggled to apply, according to the inspector general’s report. Lawmakers in both parties have complained for years that overtly political groups on the left and right have taken advantage of the rules to claim tax-exempt status and hide the identities of their donors.

“There are countless political organizations at both ends of the spectrum masquerading as social welfare groups in order to skirt the tax code,” Baucus said. “Once the smoke of the current controversy clears, we need to examine the root of this issue and reform the nation’s vague tax laws pertaining to these groups.”

Some Republicans hope to use an upcoming debate over increasing the federal government’s borrowing authority to trigger action on tax change. The government is expected to reach the borrowing limit by early fall, raising the possibility of another debt standoff like the one in 2011 that brought it to the brink of default.

Details are fluid, but congressional aides have been working on mechanisms to streamline the process of passing a tax package, in exchange for raising the debt ceiling, perhaps guaranteeing floor votes on bills approved by the tax-writing committees in the House and Senate.

President Barack Obama, however, has said he won’t negotiate over raising the debt ceiling.

Obama has called for an overhaul of corporate taxes, and he laid some groundwork to accomplish that in his latest budget proposal. He also has said he wants to do comprehensive tax reform as part of a broad budget deal that cuts spending and reformulates entitlement programs. Such a grand bargain has proven elusive.

Camp and Baucus say they are open to a process that links tax reform to the debt ceiling. But Baucus warns: “I don’t want to be part of something that’s political or partisan. But I do want to be part of something that’s practical and pragmatic that looks like it’s going to advance the ball.”

Baucus, who has been in the Senate since 1978, announced in April he won’t run for re-election in 2014. He said he will focus much of his remaining time in the Senate on trying to steer a tax package through Congress.

Camp says he is committed to passing a tax bill out of his committee by the end of the year. There is no guarantee the full House would take up the bill, but Speaker John Boehner, R-Ohio, has signaled his support for the effort by reserving the prestigious bill number HR 1 for a tax overhaul measure.

Lawmakers in both parties are convinced that simpler, easier-to-understand tax laws would spur economic activity. But there are significant partisan differences.

The Republican recipe calls for reducing or eliminating tax breaks that benefit targeted taxpayers, and using all the additional revenue to reduce overall rates for everyone. The tax system would raise about the same amount of money, but businesses could focus on being more efficient instead of trying to take advantage of targeted tax breaks, supporters say.

Obama and Democratic leaders in Congress also want to reduce or eliminate various tax breaks. Overall income tax rates would be lower, but the wealthy would pay more each year because they would lose certain exemptions, deductions and credits.
