California Can Preserve State and Local Tax Deduction, Even If Congress Ends It

Sacramento Bee  online


If Republicans’ tax overhaul passes next week, California taxpayers are likely to lose many of the state and local deductions that saved them more than $100 billion on their taxes in 2015. But legislative staffers and tax law experts are already gaming out ways to adjust the state’s tax code to offset the loss of those deductions and counter other changes to federal taxes...

The Hidden Costs of Cliff Effects in the Internal Revenue Code

University of Pennsylvania Law Review


Cliff effects in the Internal Revenue Code trigger a sudden increase of federal tax liability when some attribute of a taxpayer—most commonly income—exceeds a particular threshold value. As a result, two taxpayers in nearly identical economic situations can face considerably different tax liabilities depending on which side of the triggering criterion they fall. The magnitude of the equity and efficiency costs associated with cliff effects is significant: cliff effects are attached to tax provisions amounting to hundreds of billions of dollars, the majority of which are targeted at low- and moderate-income taxpayers...

Form 1023-EZ and the Streamlined Process for the Federal Income Tax Exemption: Is the IRS Slashing Red Tape or Opening Pandora's Box?

University of Pennsylvania Law Review Online


On July 1, 2014, the Internal Revenue Service (IRS) released Form 1023-EZ, a streamlined version of the application required of all organizations seeking federal tax-exempt status under section 501(c) of the Internal Revenue Code. By stripping away familiar elements like the narrative of specific activities, financial projections, and provision of organizing documents, Form 1023-EZ requires dramatically less time to complete and represents a radical change to a decades-old process...

From Business Tax Theory to Practice

Clinical Law Review

(with Alina Ball)


The past decade has seen a dramatic increase in the number of business law clinics in legal academia. This increase in clinical transactional courses has not, however, resulted in a congruent rise in transactional tax clinical offerings. Although tax issues, including federal, state, and local tax matters, are an integral consideration in nearly every business transaction, most business law clinics explicitly exclude tax representation from their client services...

How SALT Deduction Repeal Promotes State Capture of Federal Charitable Contributions

The Surly Subgroup


The current version of the GOP tax bill dramatically limits the deductibility of state and local taxes. For individuals, the deduction for state and local income taxes is eliminated entirely and the deduction for state and local property taxes is limited to the first $10,000. [fn.1] Though much has been said about the proposal, there has been little discussion about how eliminating the state and local tax deduction dramatically incentivizes (1) states to solicit charitable contributions in exchange for state tax credits and (2) taxpayers to make these charitable contributions.

Tax Compliance in a Decentralizing Economy

Georgia State law Review


Tax compliance in the United States has long relied on information from centralized intermediaries—the financial institutions,employers, and brokers that help ensure income is reported and taxes are paid. Yet while the IRS remains tied to these centralized entities,consumers and businesses are not. New technologies, such as sharing economy platforms (companies such as Airbnb, Uber, and Instacart)and the blockchain (the platform on which various cryptocurrencies are based) are providing new, decentralized options for exchanging goods and services...

State Responses to Federal Tax Reform: State Charitable Tax Credits

Special Report, Tax Notes

(with Joseph Bankman, David Gamage, Jacob Goldin, Daniel Hemel, Darien Shanske, Kirk J. Stark, and Dennis J. Ventry, Jr.)


Several states are considering new tax credits that would reduce tax liability based on donations made by a taxpayer in support of various state programs. In general, taxpayer contributions to qualifying organizations — including public charities and private foundations, as well as federal, state, local, and tribal governments — are eligible for the federal charitable contribution deduction under section 170. In our previous article, we explained how current law supports the view that qualifying charitable contributions are deductible under section 170, even when the donor derives some federal or state tax benefit by making the donation. We referred to this treatment as the “full deduction rule.”...

Many states provide tax incentives for charitable giving, typically to encourage private donations to targeted activities, such as natural resource preservation, private school tuition scholarships, college financial aid, shelters for victims of domestic violence, and various other state-supported programs. Under these programs, taxpayers receive state income tax credits for donations to governments, government-created funds, and nonprofits....

Hyperlocal Responses to the SALT Deduction Limitation

Stanford Law Review Online

Manoj Viswanathan

The Tax Cuts and Jobs Act, enacted in December 2017, places a $10,000 limit on the federal deduction for payments of state and local taxes (“SALT”). Several states with high numbers of adversely affected taxpayers have proposed or enacted legislative workarounds to this new cap. Much has been said about these state-level responses, but there has been little analysis of local-level effects or of how local governments could similarly respond. This essay addresses that gap by (1) statistically modeling the number of taxpayers affected by the SALT deduction limitation at a ZIP-code-by-ZIP-code (rather than state-by-state) level, and (2) proposing locality-based strategies relevant to taxpayers throughout the U.S., and not just those living in highly affected states. A hyperlocal analysis provides several key insights. First, although blue states are generally more affected by the SALT deduction limitation, many solidly red states contain high concentrations of affected taxpayers. Focusing on statewide effects masks the extent to which large numbers of affected taxpayers exist in seemingly unaffected areas. Second, although recent SALT workarounds have focused on state income taxes, there is ample opportunity for mitigating the effects of the SALT deduction limitation by focusing instead on property taxes. This would allow cities or counties, rather than states, to implement SALT workarounds tailored to their residents. This is especially relevant for taxpayers in states without a personal income tax. Third, SALT workarounds focusing on property taxes recoup more lost SALT deductions (on a percentage basis) for middle class taxpayers than for the wealthy, possibly giving these workarounds some bipartisan appeal.
