Tax Whistleblowing Legal Resources

Kirby McInerney advocates for harnessing the power of whistleblowers to report on tax violations. We have collected data on tax whistleblower programs to help legislators and regulators evaluate the programs and see the benefits they provide to their taxpayers.

Tax Whistleblowers Promote Tax Fairness and Help Close the Tax Gap

The federal government and state governments are increasingly realizing that giving incentives to whistleblowers to report on tax violations helps tax law enforcement promote fairness among taxpayers and ensure that everyone pays the taxes they are supposed to pay.

In April 2021, the IRS Commissioner estimated that $1 trillion in federal taxes go unpaid each year. That marks a striking increase over the last analysis of the "tax gap" between the amount of taxes paid and the amount owed.  The IRS analysis of 2011 to 2013 showed a $441 billion annual tax gap, with $381 billion of that unpaid even after tax audits and other enforcement efforts. States have large tax gaps of their own. In New York, for example, the annual tax gap is estimated to be about $10 billion.

The government needs new tools to close the tax gap, and whistleblowers can help. Tax whistleblowers often bring forward direct, specific evidence of tax violations and demonstrate how the claims can be proved. Whistleblowers and their counsel can provide ongoing assistance throughout a case by giving their insights and applying their expertise to help the case succeed.

Tax Whistleblowers Help Multiply the Government’s Tax Enforcement Resources

Government tax enforcement is always constrained by government budgets. Tax whistleblowers expand those resources with great returns for little cost.

The 10 years of experience with tax cases under the New York False Claims Act demonstrates that the government's return on investment is about 3,600%.
  • Recoveries in tax matters under the New York False Claims Act
  • Less Whistleblower awards
  • Less Estimated 10 yr. government enforcement costs
  • Net gains to New York
  • Return on Investment

The False Claims Act Model vs. the IRS Agency-Based Model

The IRS whistleblower program adds an access point to the IRS’ previously existing structure, which relies in large part on audits of certain taxpayers.

New York and Washington DC’s False Claims Acts explicitly invite tax whistleblowers to bring qui tam cases under their state False Claims Acts for violations of any types of taxes. The Illinois False Claims Act expressly permits cases about sales taxes and any type of taxes other than income taxes. Tax qui tams are also possible under the False Claims Acts of Indiana, Rhode Island, Delaware, Hawaii, Nevada, and New Hampshire.

Additional states have been exploring the creation of tax whistleblower programs using either the False Claims Act model or the agency-based model.

The table below compares features of these two models:
Issue IRS Whistleblower Program Tax False Claims Act Cases
Tax types All federal taxes State and local taxes for the relevant state (in NY & DC, any type of tax; the IL program excludes income taxes)
Violations addressed Any type of tax underpayment or violation, whether by fraud, mistake or otherwise Limited to knowing violations
Agency responsible for pursuing claims IRS The state Attorney General, but with certain involvement by the department of revenue
Damages that can be imposed Tax underpayments plus penalties and interest Treble damages plus False Claims Act penalties per violation
Thresholds for action No thresholds must be met before a claim can be made Varies by program: IL has no thresholds; NY requires that the defendant have net income or sales of at least $1 million in any tax year and that damages pled are at least $350,000; DC has thresholds similar to NY
Whistleblower award amounts 15-30% of government’s recovery; awards are mandatory for recoveries over $2 million and discretionary for smaller amounts 15-30% of government’s recovery
Anonymity of whistleblower Anonymity is largely assured Case is initially filed under seal, but whistleblower should not expect to remain anonymous forever
Opportunity for the whistleblower to proceed with case if government does not None Whistleblower can choose to proceed with the case if the government declines; if successful, whistleblower award will be 25% to 30% of government recovery
Process for starting action Submitting a Form 211 with supporting information Filing an under-seal lawsuit and serving the Attorney General (but not the defendant)
Penalty for bringing a frivolous action None Costs can be awarded to the defendant
Length of action Generally at least 7-10 years Varies widely, from one year to about 8
Whistleblower participation after initial filing Generally none after filing of Form 211, but whistleblower will sometimes be interviewed and asked for additional input Depending on the case, the whistleblower can be very involved in assisting with the government’s investigation; whistleblower can proceed with a declined case
Statute of limitations Generally 3 years; the period continues to run even after the whistleblower filing, and claims may expire while investigation is progressing Varies by program; in NY, 10 years; the period is stopped by the filing of the lawsuit, so existing claims do not expire during the investigation
Fee shifting for attorneys’ fees and costs None Whistleblower can recover reasonable attorneys’ fees and costs, in addition to whistleblower’s percentage award

Tax cases under the New York False Claims Act have, in the program’s ten years, resulted in recoveries of over $585.2 million from 24 cases that were either brought by whistleblowers or initiated by the government.  Nearly $111.9 million has been paid in whistleblower awards. To date, 46 whistleblower-initiated tax New York False Claims Act cases have been made public, of which 18 settled, 1 is pending after government intervention, 5 are pending after government declination, 8 were voluntarily discontinued, and 13 were dismissed.

In April 2020, the NY Attorney General's Office disclosed that in ten years there had been 204 tax-related matters under the New York False Claims Act, about 85% of which (or about 175) were brought by whistleblowers. The AG's Office declined to intervene in about 90 of those cases, about one-third of which were made public. (Under the NYFCA, relators can choose to keep a declined case under seal if they do not pursue it.) Roughly 70 tax qui tam cases remain under investigation by the AG's Office.
