Duty Accrual Reconciliation: Closing the Gap Between Accrued and Filed Duty

What is duty accrual reconciliation?

Duty accrual reconciliation is the month-end control that compares three numbers that should agree and almost never do: the duty finance accrued, the duty your entries actually filed at, and the duty your brokers billed. We call this the Accrual Triangle. When its sides diverge and nobody signs off on the spread, margin is misstated, inventory is valued wrong, and classification errors age quietly past their recovery windows.

Duty accrual reconciliation compares accrued, filed, and billed duty per entity, per month. The filed number is the truth; the other two drift from it. Under current volatility, 72 percent of trade professionals call U.S. tariffs their top risk per Thomson Reuters' 2026 Global Trade Report (November 2025), a duty accrual set annually is not an estimate, it is a guess that compounds monthly on every imported unit.

Why does accrued duty never match filed duty?

Each side of the Accrual Triangle is built by different people from different data at different times:

Side	Built by	From	Drift source
Accrued	Finance, at close	Last year's blended rate	Tariff actions, sourcing shifts, mix changes
Filed	Brokers, at entry	The live tariff stack per line	Misclassification, missed preferences
Billed	Broker invoicing, weeks later	Duty plus fees plus brokerage, bundled	Billing errors, timing, bundling

The structural problem is that finance usually reconciles accrued to billed, the two soft numbers, because the filed truth sits in broker ABI files and ACE where finance never looks. That is the Five-System Split doing its damage at close: the one number grounded in law is the one missing from the working papers. Billed-side drift is its own audit, covered in the freight invoice audit guide.

How do you build an accrual rate that tracks reality?

Derive it, do not inherit it. The rate should come from the live tariff stack of what you actually import, weighted by value: per product and origin, base duty plus Section 232, Section 301, Chapter 99, and Section 122 layers, as covered in how tariff stacking works. Then refresh it on Rate-Refresh Triggers rather than a calendar:

1. A tariff action touching any heading you import
2. A sourcing-country shift on a top-20 product
3. A product-mix change moving more than a few points of import value
4. A preference program qualification or expiry
5. Minimum quarterly, even if nothing above fired

GingerControl's Tariff Calculator covers the full U.S. tariff stack across 200+ countries, which is exactly the per-product rate truth a derived accrual model needs, and the same stack math your entries should be filing at, so accrual versus filed variance becomes a real signal instead of noise.

What should the close-week routine actually look like?

Quotable insight: The duty accrual is the only material cost estimate most multinationals never reconcile to its legal source document. Finance reconciles accrued to billed, two soft numbers, while the filed rate, the one grounded in the tariff schedule, never enters the working papers. In a regime where the top-risk item moves by proclamation, the Accrual Triangle's third side is not optional, it is the control.

The Close-Week Five, one entity at a time, biggest duty payer first:

1. Pull the month's entries and compute the blended filed rate per entity
2. Compare to the accrual rate; document the spread and who approved it
3. Sample the largest-spread lines against the modeled stack, persistent excess points to recoverable errors
4. Reconcile billed invoices to filed duty, fees separated from duty
5. Log triggers fired this month and whether the rate refreshes next close

Teams at Level 0 or 1 of the Four Levels of Import Financial Control should start with step 1 alone, it is the analyst-week that prices everything else.
