TC 694: Designated Payment of Fees and Collection Costs

What the code actually does

IRS Document 6209, Section 8A scopes TC 694 tightly: it is the "Designated Payment of Fees and Collection Costs," and it exists to pay down TC 360 lien-filing and levy/sale-cost assessments specifically, not tax, interest, or an ordinary penalty.

That narrow scope is enforced structurally, not just by convention: Doc 6209 states "the money amount must be equal to or less than the net amount of unreversed TC 360's excluding amount of previously applied TC 694's," and the transaction "will also go unpostable if there is no TC 360 present." A TC 694 has nothing to attach to on a module with no outstanding fee assessment.

Why the fee outlives the tax it secured

This code matters because TC 360 fees are a documented exception to the usual rule that resolving the tax resolves everything attached to it — the TC 360 page covers how lien and levy costs "can survive the tax it was securing." TC 694 is the specific tool for paying that surviving fee down once the rest of the liability is gone.

A practitioner closing out a case who assumes a zero tax balance means nothing is left owed should check specifically for an unreversed TC 360 — that balance does not disappear with the underlying assessment and needs its own designated payment to clear.

What happens when the math is wrong

Because the transaction is capped against the net unreversed TC 360 amount, an oversized TC 694 payment does not partially post and refund the excess — Doc 6209's unpostable condition means the entire transaction fails to post until the amount is corrected. Confirm the exact unreversed TC 360 balance before submitting a TC 694, rather than estimating from a balance-due notice that may bundle several liability types together.

An unpostable TC 694 does not simply vanish or bounce back to the taxpayer — a transaction that "goes unpostable" sits in the IRS's own unpostable inventory pending manual resolution, not an instant process. That is the actual answer to a client asking where their payment went: it is being held for correction, not lost and not yet applied anywhere on the account.

IRM 21.5.8.4.1 lists TC 694 alongside TC 640, 670, 680, and 690 as one of the misapplied-payment codes eligible for Designated Payment Code "00" when transferred without an original DPC — the standard credit-transfer fix if a TC 694 lands on the wrong module.

What TC 694 gets confused with

It gets confused with TC 690, the designated payment of a penalty assessment — a structurally similar but substantively different designation, since TC 694 is capped against fees specifically and TC 690 is not capped the same way.

It gets confused with an ordinary lien-release payment. Paying the TC 360 fee with a TC 694 does not itself release the IRC §6321 federal tax lien or its Notice of Federal Tax Lien filing; lien release follows its own procedure once the full liability, including fees, is satisfied.

It gets confused with a payment that simply "did not go through" when it actually went unpostable for exceeding the unreversed TC 360 balance — the fix is correcting the amount, not re-submitting the same payment.

The practitioner's actual next step

Confirm the exact unreversed TC 360 balance before submitting a TC 694 payment, since an oversized amount will go unpostable rather than partially apply.

Check specifically for outstanding lien or levy fees before telling a client their account is fully resolved once the tax balance reaches zero.

If a TC 694 lands on the wrong module, correct it through the standard credit-transfer process rather than submitting a duplicate payment.

Confirm lien release separately once fees are paid — TC 694 satisfies the fee, it does not itself trigger a release.
