IRS's sharply increased focus on international tax enforcement is taking place without adequate servicewide coordination or help for taxpayers trying to comply with myriad confusing rules, IRS Taxpayer Advocate Nina Olson says in a report. “The lack of coordination may undermine international enforcement initiatives and discourage future compliance by taxpayers dealing with the complexity and procedural burdens of the international tax rules,” the report says. It urges IRS to restore its International Planning and Operations Council (IPOC), “the only servicewide forum for addressing international taxpayer service issues,” and to create a new subgroup within IPOC.
