TC 530: Currently Not Collectible

What the code actually does

TC 530 moves a balance-due account out of active collection. IRS Document 6209, Section 8A puts it plainly — "a balance due account is considered currently not collectible" — and records that the "Closing Code is 01-39." The IRM makes the closing code mandatory rather than decorative: IRM 5.16.1.2 states that "accounts may be reported CNC for a variety of reasons using transaction code (TC) 530" and that "it is a requirement that (TC) 530 be defined by the appropriate closing code (cc)."

Nothing is forgiven. The liability stays assessed, interest and any failure-to-pay penalty keep accruing, and the Service can return to the account. What changes is that active collection stops for now.

The closing code is the whole meaning

Two accounts can both show a TC 530 and be in completely different positions, because the closing codes describe unrelated situations. The IRM’s table separates them. Closing code 03 is "inability to locate the taxpayer or assets" and 12 is "inability to contact a taxpayer although the address is known and there is no means to enforce collection" — neither reflects any finding about the client’s finances. Closing codes 24 through 32 are the hardship band, where "collection of the liability would create a hardship for taxpayers by leaving them unable to meet necessary living expenses." Those are the ones that follow a financial statement.

Others are structural. Closing code 05 is "complete expiration of the statutory period for collection," which is not a hardship determination at all but a write-off of a dead statute. Code 07 covers a corporation, exempt organization or LLC "liquidated in bankruptcy," code 08 is "death of an individual with no collection potential," code 09 is "accounts below tolerance," and code 10 covers entities that "are inactive and defunct with no assets." The IRM also notes that codes 37 and 38 are used by Private Debt Collection to shelve cases and code 39 by the Inventory Delivery System — a TC 530 in that band means an account was set aside administratively, not that anyone assessed anything about the taxpayer.

So the first question on seeing a TC 530 is never "is the client in CNC?" It is "which closing code?" A hardship 24–32 supports a very different conversation from an unable-to-locate 03.

CNC does not stop the collection statute

This is the most costly misreading of the code, because it runs the wrong direction from the client’s interest. Time in currently-not-collectible status counts. IRM 5.1.19.3 sets out the case actions that suspend or extend a collection statute expiration date, and its table lists TC 468, TC 480, TC 488, TC 500, TC 520 with its suspending closing codes, TC 550, and two TC 971 action codes. TC 530 does not appear on it. The chapter names the code once, in an unrelated example about applying seizure proceeds.

The practical consequence is favourable and worth telling clients: a genuine hardship CNC on an aging liability can run out the clock. That makes the interaction between the CNC status and the statute worth calculating rather than assuming, which is what the collection statute calculator is for.

CNC does not keep a lien off the record

Clients frequently hear "not collectible" and infer "nothing further will happen." The IRM says close to the opposite. IRM 5.16.1.2 instructs that "in general, a Notice of Federal Tax Lien (NFTL) should be filed on accounts being reported CNC when the aggregate unpaid balance of assessments equals or exceeds $10,000.00." That figure is an administrative threshold set by the manual, not a statutory amount, and it is a filing guideline rather than a bar — the same subsection points to the lien-determination criteria and exceptions in IRM 5.12.2.

The sequencing is explicit too: the IRM tells revenue officers that "after the NFTL indicator (TC 582) is pending, the case can be closed as CNC." A lien indicator appearing shortly before a TC 530 is the normal order of events, not a sign that something went wrong.

What TC 530 gets confused with

It gets confused with an accepted offer or a closed account. It is neither. The balance remains, and the account can be reactivated — TC 531 returns it to active collection on a fresh determination, while TC 537 is the system-generated reversal that fires because a new liability appeared rather than because anyone reconsidered the hardship.

It is also confused with a statute write-off. Only closing code 05 means the statute expired, and even then the write-off code that removes an individual expired assessment inside a still-open module is a different transaction entirely. Reading any TC 530 as "the debt is gone" overstates what the code did; running the client’s actual numbers through the CNC eligibility calculator before advising on the status is the safer path.
