The Internal Revenue Service continues to assign delinquent tax debts to private collection agencies under a program Congress has repeatedly reauthorized, even as the Treasury Inspector General for Tax Administration has issued a series of public audits on how those contractors treat taxpayers and how the Service selects cases.

The private debt collection program, often abbreviated PDC, was revived in statute after earlier experiments. The Fixing America’s Surface Transportation Act of 2015 directed the Service to use private firms for certain inactive tax receivables. Later legislation and appropriations language kept the pipeline open. IRS budget justifications and procurement notices identify multiple award cycles to collection contractors that work inventories the government itself has not actively pursued.

TIGTA’s public reports do not allege a single smoking-gun conspiracy. They describe operational patterns. Audits have found that some accounts assigned to private agencies involved taxpayers who, according to the Inspector General’s sampling, should have been excluded under the Service’s own criteria—among them taxpayers in designated hardship categories, those already working with the Taxpayer Advocate Service, or accounts that did not meet the “inactive” definition as TIGTA applied it.

The Inspector General has also reported that complaint volumes and quality-control findings at contractors have not always been reconciled quickly with IRS oversight offices. TIGTA has recommended tighter filters before assignment, better monitoring of telephone and written contacts, and clearer paths for taxpayers to halt collection when they claim they cannot pay or that the debt is in dispute. The Service, in management responses published with those reports, has typically agreed in part, cited statutory collection requirements, and described process changes already underway.

Private firms are paid a commission on amounts they collect, a structure set in the authorizing statute and in the contracts. IRS and Treasury budget materials have shown collections attributed to the program alongside the commissions paid. Independent reviews, including TIGTA and the National Taxpayer Advocate’s annual reports to Congress, have questioned whether net proceeds, after commissions and IRS administrative cost, justify the rights risk—especially when some assigned inventory later proves uncollectible or wrongly placed.

The Taxpayer Advocate Service, an independent office inside the IRS, has for years told Congress that private collectors generate a disproportionate share of TAS cases relative to the size of the PDC inventory. Those reports, submitted under 26 U.S.C. § 7803, describe taxpayers who said they were contacted despite pending offers in compromise, installment agreements, or identity-theft indicators. TAS has asked for statutory or administrative carve-outs that the collection program, as written, does not fully provide.

Procurement records show the IRS has competed and awarded PDC work to a rotating set of firms under multiple-award vehicles. Public notices name companies that have held or hold such work; the awards are not classified. Contract clauses require compliance with the Fair Debt Collection Practices Act as applied to federal tax debts, IRS Publication 1 (Your Rights as a Taxpayer), and restrictions on contacting taxpayers at certain times or about certain account types. TIGTA’s fieldwork has tested whether those clauses are followed in sampled calls and letters.

Officials at the IRS have publicly described the program as a congressional mandate to collect tax that would otherwise go uncollected, and as a way to free IRS revenue officers for higher-priority work. That position appears in testimony before the House Ways and Means Committee and the Senate Finance Committee, and in the Service’s annual PDC reports to Congress. TIGTA has not disputed that some dollars are collected. It has disputed whether assignment rules, notice quality, and complaint handling meet the taxpayer-rights framework Congress also enacted in the IRS Restructuring and Reform Act of 1998 and subsequent taxpayer-bill-of-rights language.

The tension is therefore statutory as much as operational. One set of laws tells the Service to outsource inactive receivables. Another set, and TIGTA’s audit mandate, tells the same agency to protect against coercive or erroneous collection. Dockets and IG reports do not show TIGTA seeking to cancel the program outright in every instance; they show repeated recommendations that the IRS tighten the front-end filter and the back-end complaint process while contractors continue to work the remaining inventory.

GAO has also examined aspects of federal private collection and IRS enforcement resource allocation, generally in unclassified reports. Those reviews sit alongside TIGTA’s more tax-specific sampling. Together they form the public paper trail: awards continue, commissions are paid, and the Inspector General continues to publish findings that the assignment and contact process still produces cases that, in the auditors’ view, never should have left the government’s own files.

No classified document is required to see the mismatch. It is in the open: contract awards on SAM.gov and IRS procurement pages; TIGTA reports numbered and posted on tigta.gov; National Taxpayer Advocate purple books; IRS PDC reports to Congress; and hearing records in which members ask why complaint rates and exclusion errors persist after multiple “corrective action” letters.

Whether Congress will amend the mandate, or whether the Service will further narrow the inventory without new law, remains a legislative and administrative question. The record as it stands is that private-collection awards and TIGTA taxpayer-rights audits occupy the same policy space, year after year, without a full reconciliation in the published findings.
