Twelve States Offer Profitable Tax Shelter to Private School Voucher Donors; IRS Proposal Could Fix This

October 2, 2018 • By Carl Davis

A proposed IRS regulation would eliminate a tax shelter for private school donors in twelve states by making a commonsense improvement to the federal tax deduction for charitable gifts. For years, some affluent taxpayers who donate to private K-12 school voucher programs have managed to turn a profit by claiming state tax credits and federal tax deductions that, taken together, are worth more than the amount donated. This practice could soon come to an end under the IRS’s broader goal of ending misuse of the charitable deduction by people seeking to dodge the federal SALT deduction cap.

Tax Cuts 2.0 – South Carolina

September 26, 2018 • By ITEP Staff

The $2 trillion 2017 Tax Cuts and Jobs Act (TCJA) includes several provisions set to expire at the end of 2025. Now, GOP leaders have introduced a bill informally called “Tax Cuts 2.0” or “Tax Reform 2.0,” which would make the temporary provisions permanent. And they falsely claim that making these provisions permanent will benefit […]

Gas Taxes Rise in Seven States, Including an Historic Increase in Oklahoma

June 26, 2018 • By Carl Davis

A rare sight is coming to Oklahoma. The last time the Sooner State raised its gas tax rate, the Berlin Wall was still standing, and Congress was debating whether to ban smoking on flights shorter than two hours. Fast forward 31 years, and Oklahoma is finally at it again. On Sunday, the state’s gas tax rate will rise by 3 cents and its diesel tax rate by 6 cents. Both taxes will now stand at 19 cents per gallon—still among the lowest in the country. But Oklahoma isn’t the only state where gas taxes will soon rise.

June 22, 2018 • By Dylan Grundman O'Neill

South Carolina legislators will return next week to try to finalize a few issues before the end of their session and fiscal year on June 30th, including the question of how to respond to the federal Tax Cuts and Jobs Act (TCJA). That's a short timeframe with some important questions at stake, and some misinformation has been spread, so here's a quick guide to the facts, issues, and options.

Most States Have Raised Gas Taxes in Recent Years

May 22, 2018 • By Carl Davis

An updated version of this blog was published in April 2019. State tax policy can be a contentious topic, but in recent years there has been a remarkable level of agreement on one tax in particular: the gasoline tax. Increasingly, state lawmakers are deciding that outdated gas taxes need to be raised and reformed to fund infrastructure projects that are vital to their economies.

State Rundown 1/12: Tax Cut Tunnel Vision Threatens to Bore State Budget Holes Even Deeper

January 12, 2018 • By ITEP Staff

As states continue to sift through wreckage of the federal tax cut bill to try to determine how they will be affected, two things should be clear to everyone: the richest people in every state just got a massive federal tax cut, and federal funding for shared priorities like education and health care is certain to continue to decline. State leaders who care about those priorities should consider asking those wealthy beneficiaries of the federal cuts to pay more to the state in order to minimize the damage of the looming federal funding cuts, but so far policymakers in Idaho,…

How the Final GOP-Trump Tax Bill Would Affect South Carolina Residents’ Federal Taxes

December 16, 2017 • By ITEP Staff

The final tax bill that Republicans in Congress are poised to approve would provide most of its benefits to high-income households and foreign investors while raising taxes on many low- and middle-income Americans. The bill would go into effect in 2018 but the provisions directly affecting families and individuals would all expire after 2025, with […]

Private Schools Donors Likely to Win Big from Expanded Loophole in Tax Bill

December 14, 2017 • By Carl Davis

For years, private schools around the country have been making an unusual pitch to prospective donors: give us your money, and you’ll get so many state and federal tax breaks in return that you may end up turning a profit. Under tax legislation being considered in Congress right now, that pitch is about to become even more persuasive.

Tax Bill Would Increase Abuse of Charitable Giving Deduction, with Private K-12 Schools as the Biggest Winners

December 14, 2017 • By Carl Davis

In its rush to pass a major rewrite of the tax code before year’s end, Congress appears likely to enact a “tax reform” that creates, or expands, a significant number of tax loopholes.[1] One such loophole would reward some of the nation’s wealthiest individuals with a strategy for padding their own bank accounts by “donating” to support private K-12 schools. While a similar loophole exists under current law, its size and scope would be dramatically expanded by the legislation working its way through Congress.[2]

How the House and Senate Tax Bills Would Affect South Carolina Residents’ Federal Taxes

December 6, 2017 • By ITEP Staff

The House passed its “Tax Cuts and Jobs Act” November 16th and the Senate passed its version December 2nd. Both bills would raise taxes on many low- and middle-income families in every state and provide the wealthiest Americans and foreign investors substantial tax cuts, while adding more than $1.4 trillion to the deficit over ten years. The graph below shows that both bills are skewed to the richest 1 percent of South Carolina residents.

How the Revised Senate Tax Bill Would Affect South Carolina Residents’ Federal Taxes

November 14, 2017 • By ITEP Staff

The Senate tax bill released last week would raise taxes on some families while bestowing immense benefits on wealthy Americans and foreign investors. In South Carolina, 51 percent of the federal tax cuts would go to the richest 5 percent of residents, and 11 percent of households would face a tax increase, once the bill is fully implemented.

How the House Tax Proposal Would Affect South Carolina Residents’ Federal Taxes

November 6, 2017 • By ITEP Staff

The Tax Cuts and Jobs Act, which was introduced on November 2 in the House of Representatives, includes some provisions that raise taxes and some that cut taxes, so the net effect for any particular family’s federal tax bill depends on their situation. Some of the provisions that benefit the middle class — like lower tax rates, an increased standard deduction, and a $300 tax credit for each adult in a household — are designed to expire or become less generous over time. Some of the provisions that benefit the wealthy, such as the reduction and eventual repeal of the estate…

GOP-Trump Tax Framework Would Provide Richest One Percent in South Carolina with 57.1 Percent of the State’s Tax Cuts

October 4, 2017 • By ITEP Staff

The “tax reform framework” released by the Trump administration and congressional Republican leaders on September 27 would not benefit everyone in South Carolina equally. The richest one percent of South Carolina residents would receive 57.1 percent of the tax cuts within the state under the framework in 2018. These households are projected to have an income of at least $478,100 next year. The framework would provide them an average tax cut of $52,250 in 2018, which would increase their income by an average of 4.6 percent.

In South Carolina 25.8 Percent of Trump’s Proposed Tax Cuts Go to People Making More than $1 Million

August 17, 2017 • By ITEP Staff

A tiny fraction of the South Carolina population (0.2 percent) earns more than $1 million annually. But this elite group would receive 25.8 percent of the tax cuts that go to South Carolina residents under the tax proposals from the Trump administration. A much larger group, 49.4 percent of the state, earns less than $45,000, but would receive just 6.4 percent of the tax cuts.

Trump Tax Proposals Would Provide Richest One Percent in South Carolina with 49.5 Percent of the State’s Tax Cuts

Earlier this year, the Trump administration released some broadly outlined proposals to overhaul the federal tax code. Households in South Carolina would not benefit equally from these proposals. The richest one percent of the state’s taxpayers are projected to make an average income of $1,134,000 in 2018.
