In short: Understanding the TTB monthly processing report (Form 5110.40) is essential for distilleries to maintain federal compliance. This report tracks all spirits entering the processing account, including blending, filtering, and bottling activities, ensuring accurate proof gallon calculations and tax liability tracking for the Alcohol and Tobacco Tax and Trade Bureau.
Understanding the TTB monthly processing report (Form 5110.40) is a fundamental part of running a compliant distilled spirits plant. This mandatory federal filing details every drop of alcohol that is blended, proofed, filtered, and bottled within your distillery during a calendar month. By accurately recording these operations, distillers ensure they pay the exact excise tax owed and maintain good standing with federal regulators.

What is the TTB processing account?
To make sense of the monthly reports, you first need to understand how federal regulators view the physical layout and operations of your distillery. A distilled spirits plant is generally divided into three distinct operational accounts: production, storage, and processing. The production account is where fermentation happens and mash is run through the still. The storage account is where bulk spirits rest in barrels or holding tanks to age.
The processing account is the final stage before your spirits reach the consumer. Active work happens here. When you dump a barrel of bourbon from the rickhouse to prepare it for a bottling run, that liquid physically and on paper moves out of the storage account and enters the processing account. Any modifications to the spirit, including diluting it with water, adding flavoring, passing it through filtration housings, and finally putting it into a bottle, are considered processing activities.
Understanding the TTB monthly processing report (Form 5110.40) mechanics
According to federal regulations outlined in 27 CFR Part 19, operators must file reports summarizing the activities in each of their operational accounts every month. The document specifically used to summarize the processing account is TTB Form 5110.40.
This form is divided into sections that track your bulk liquid, your non-alcoholic ingredients, and your finished packages. Regulators demand precision on this form. Every entry tracking the movement of spirits must be recorded in proof gallons, not simply liquid volume. The goal of the form is to provide regulators with a clear mathematical trail showing exactly what raw materials entered the processing area, what happened to them, and what finished goods left the bonded premises.
How do you track bulk spirits and ingredients?
Part I and Part II of the processing report handle the raw materials that go into your final product. Part I is strictly for tracking bulk spirits. In this section, you must record the proof gallons of spirits that were on hand on the first day of the month. You will also log spirits that were received from customs or transferred in bond from other distilleries.
Crucially, Part I is where you record spirits dumped from your own storage account. When you pull barrels from the rickhouse, a precise regauge is required. The amount of liquid coming out of a barrel will almost always be lower than what went in years prior due to evaporation. Your storage account absorbs that natural loss. However, once the spirit is dumped into a processing tank, a new gauge is taken. This new measurement sets the baseline for your processing account. From that moment on, any subsequent loss is considered a processing loss. If a hose leaks, a pump fails, or a filter pad absorbs a significant amount of whiskey, you must document those missing proof gallons in Part I. Regulators heavily scrutinize unexplained processing shortages because they represent lost tax revenue.
Part II of the form is dedicated to non-alcoholic ingredients. If you produce flavored whiskey, gin, or liqueurs, this is where you account for the sugar, botanical extracts, or other flavoring materials introduced during the processing phase.
What goes into Part III for bottled spirits?
Part III of the form is where bulk liquid officially becomes a finished good. When you fill bottles and seal them, the liquid leaves Part I and enters Part III.
In this section, you record the total proof gallons that were successfully bottled and packaged during the month. You must also account for how those finished bottles left the processing account. Most commonly, bottles are removed subject to tax determination, meaning they are leaving the bonded area to be sold. You will also use this section to record bottles removed for other approved purposes, such as export to another country or destruction. The physical inventory of the finished goods sitting in your bonded casing area at the end of the month must match the remaining balance on this section of the form exactly.
How do you calculate proof gallons for processing?
The math behind your monthly reporting is entirely dependent on the proof gallon. A proof gallon is defined as one liquid gallon of spirits at 100 proof, which equates to 50 percent alcohol by volume. Excise tax scales directly with the alcohol content of the liquid.
Calculating proof gallons requires multiplying your actual liquid volume, known as wine gallons, by the proof percentage. For example, if you have 100 wine gallons of whiskey resting in a processing tank at 120 proof, you multiply 100 by 1.2 to calculate your total as 120 proof gallons.
During processing, you will frequently add water to bring the spirit down to bottling strength. If you add 50 gallons of water to that same tank to lower the proof to 80, your liquid volume increases to 150 wine gallons. However, when you multiply 150 by 0.8, the result is still exactly 120 proof gallons. The total proof gallons remain mathematically identical. This constant metric is why regulators rely on proof gallons to ensure no taxable alcohol goes missing during dilution. Using an ABV to proof converter alongside precise temperature corrections is highly recommended to ensure your measurements are accurate.
What happens to spirits leaving the processing account?
When spirits finally leave the processing account, they usually enter taxpaid status. Once they are bottled and moved out of the bonded boundaries of your distilled spirits plant, the federal excise tax is officially triggered.
Many new distillery owners do not realize that federal rules prohibit serving taxpaid tasting samples inside the bonded production or processing areas. If you plan to sell bottles directly to consumers or offer tasting flights, you must designate a separate retail space. This tasting room must be physically separated from the bonded area, typically utilizing its own door and a separate point of sale system. Bottles must be officially recorded on your processing report as removed subject to tax and then physically carried over to the retail side before a single drop can be poured for a customer.
When calculating the tax owed on these removals, be aware of the Craft Beverage Modernization Act. Under current federal law, reduced excise rates apply to certain producers. The rate drops significantly to $2.70 per proof gallon on the first 100,000 proof gallons removed. Standard rates of $13.50 per proof gallon apply at higher tiers. Always check current guidance on the official TTB website to confirm your specific processing and bottling activities qualify for the reduced rate.
Why must you file a zero report if no activity occurred?
A common pitfall for new operators is ignoring their monthly reports while they wait for equipment to arrive or for their first batches to age. Realistically, the timeline from dreaming up a distillery to actually running the still can take 18 to 24 months.
However, the moment your federal basic permit is approved, your reporting obligations begin. If you have not yet produced, stored, or processed any alcohol, you are still legally required to file a zero report for the month. Submitting these blank forms communicates to the government that your business is active and you are maintaining your distillery compliance. Failing to file operations reports on time can trigger administrative audits or action against your basic permit.
Managing your tax liability and federal bonds
Your processing activities directly impact your required federal bond coverage. A distilled spirits plant must carry a bond sized to cover the potential federal tax liability of all the spirits it holds across the production, storage, and processing accounts.
The bond amount is computed by multiplying your maximum proof gallon inventory by the standard $13.50 tax rate. If your business model involves bringing in large amounts of bulk spirits from other distilleries to process and bottle, the total proof gallons on your premises will rise quickly. A surge in processing inventory could require you to increase your penal bond sum to remain compliant.
Common minimums for new operations include a $1,000 minimum withdrawal bond, while a combined unit bond covering all operations might start around $11,000 to $16,000 depending on your anticipated volume. The bond paperwork is one part of the application process that federal staff cannot correct on your behalf. Your legal company name, your employer identification number, and the penal sum must be exactly right, or your filings will be rejected.

Frequently asked questions
What is the penalty for filing Form 5110.40 late?
While specific penalties vary, failing to file your monthly operations reports on time can result in audits, financial fines, or administrative action against your basic permit.
Do I need to file Form 5110.40 if I did not bottle anything this month?
Yes, you must file a zero report every month your permit is active. Submitting a blank form keeps your permit in good standing even if no processing took place.
How does the processing account differ from the storage account?
The storage account tracks bulk spirits resting undisturbed in barrels or tanks. The processing account tracks spirits undergoing active changes like blending, proofing, filtering, or bottling.
How do I measure proof gallons for the TTB monthly processing report?
You must gauge the spirits by measuring the exact liquid volume and the true alcohol proof with temperature correction. You then multiply the wine gallons by the proof percentage to determine the total proof gallons.
