[The audit is now mentioned in Tax Connections from, I think, a tax compliance perspective]
A commenter on Brock found this link to a recent September 28, 2020 TIGTA audit, a “review to determine the effectiveness of the Internal Revenue Service’s efforts in ensuring compliance with the expatriation tax provisions under Internal Revenue Code Sections 877 and 877A…”
Expatriation is a human right.
However the United States Congress and the U.S. Treasury Inspector General for Tax Administration (TIGTA) aim to discourage anyone who renounces because they don’t want the burden of annually filing those US tax forms — there must be disincentives for these persons.
TIGTA specifically argues that without a much better IRS “Centralized effort, Congress’s attempts to create disincentives for tax-motivated expatriation via I.R.C. § 877A will not be effective”. Of course, the disincentives would be applied also to “Accidental ‘Americans'”.
The audit concluded that IRS tax compliance efforts for expatriates is a mess and found, for example:
“TIGTA found that the IRS database of expatriates was incomplete for 16,798 expatriates who did not file Form 8854. In addition, TIGTA found instances of potential nonfiling, underreporting of income, and/or payment compliance issues by expatriates. From a sample of 26 expatriates who did not file a Form 8854, five had potential unreported income over $6 million. From a sample of 61 expatriates who filed a Form 8854, 15 had potential unreported income over $17 million. Lastly, TIGTA also found that expatriates with high net worth appear to not be paying their exit tax.”
… and TIGTA made some recommendations.
