TTB Loss Reporting Requirements for Beer, Wine, and Distilled Spirits
TTB loss reporting requirements govern how breweries, wineries, and distilleries document product losses affecting federal excise tax obligations. Under 27 CFR Part 25 (beer), 27 CFR Part 24 (wine), and 27 CFR Part 19 (distilled spirits), producers must document losses from evaporation, spillage, theft, casualty, and other causes, with different treatment depending on the loss type and whether it exceeds TTB’s accepted parameters. Losses within accepted parameters generally don’t trigger federal excise tax; unusual losses may. This guide covers loss classification, documentation requirements, reporting on federal excise tax returns and operational reports, and when losses require immediate TTB notification versus routine reporting.
TTB loss reporting requirements apply to breweries, wineries, and distilleries under 27 CFR Parts 25, 24, and 19 respectively. Losses fall into several categories: evaporation losses (natural losses during aging, particularly relevant for distilled spirits and wine); spillage and processing losses during production; theft; casualty losses from fires, floods, or accidents; and other unusual losses. TTB categorizes losses as either within accepted parameters (routine losses that don’t trigger federal excise tax) or unusual losses (losses that may require federal excise tax payment if TTB determines the product would have otherwise been tax-determined). For distilled spirits under 27 CFR 19, the “angel’s share” — natural evaporation during barrel aging — is a well-recognized routine loss. For wine under 27 CFR 24, cellar losses during aging and processing follow analogous rules. For beer under 27 CFR 25, breweries document losses through their Brewer’s Report of Operations on TTB Form 5130.9. Immediate TTB notification is required for significant casualty losses, theft, and losses affecting tax determination. Written loss records under each part support routine reporting and TTB compliance visits.
The TTB Loss Reporting Framework for Beverage Alcohol
TTB loss reporting requirements exist because federal excise tax on beverage alcohol attaches at specific points in the production process (typically tax determination at bottling for spirits, first-tier removal for beer, and analogous points for wine). Losses of product that would otherwise have been subject to federal excise tax raise the question of whether tax is due on the lost product. TTB’s answer depends on how the loss occurred and whether it falls within accepted parameters.
For distilled spirits under 27 CFR Part 19, “angel’s share” — the natural evaporation of spirits during barrel aging — is a well-recognized routine loss. TTB has established parameters for expected evaporation losses that don’t trigger tax. Losses within those parameters are documented in DSP records and reported through TTB Form 5110.28 (Distilled Spirits Losses) or through the DSP’s routine operational reporting. Losses exceeding expected parameters may require federal excise tax payment.
For wine under 27 CFR Part 24, cellar losses during aging, processing, and bottling follow analogous rules. Bonded wine cellar losses within accepted parameters don’t trigger federal excise tax; unusual losses may. Wineries document losses through cellar records and report through the winery’s operational reporting. For beer under 27 CFR Part 25, breweries document losses through the Brewer’s Report of Operations on TTB Form 5130.9, with a specific loss line item on the report.
Casualty losses — from fires, floods, tornadoes, or other unexpected events — and theft require immediate TTB notification separate from routine loss reporting. TTB may provide relief from federal excise tax on casualty losses in specific circumstances, but the relief requires timely notification and documentation. Theft requires prompt reporting and law enforcement involvement. All losses affecting tax determination must be reconciled in the applicable federal excise tax return filings.
Evaporation (“Angel’s Share”)
Natural losses during aging with accepted parameters under 27 CFR 19 for spirits.
Processing Losses
Losses during production, bottling, and transfer within routine parameters.
Casualty and Theft
Losses from fires, floods, or theft requiring immediate TTB notification.
Documentation Required
Written loss records supporting routine reporting and TTB compliance visits.
The 8-Step TTB Loss Documentation and Reporting Workflow
Whether the loss is routine evaporation, spillage, or a casualty event, TTB loss documentation follows a consistent workflow.
Identify Loss Type and Cause
Categorize the loss — evaporation, spillage, transfer, casualty, theft, or unusual loss. Loss type drives reporting requirements and potential federal excise tax implications.
Measure or Estimate Loss Quantity
For quantifiable losses (spillage, casualty), measure the volume lost. For evaporation, calculate expected losses against actual measurements from gauging.
Document Loss in Production Records
Record loss details in DSP records (for spirits), cellar records (for wine), or brewery records (for beer) under the applicable 27 CFR part. Include date, quantity, cause, and witnessing personnel.
Assess Federal Excise Tax Implications
Determine whether the loss falls within accepted parameters (no federal excise tax) or represents an unusual loss (potentially triggering federal excise tax). Consult applicable 27 CFR guidance.
Immediate Notification for Casualty and Theft
Losses from fires, floods, or theft require prompt TTB notification. Contact the appropriate TTB office per current guidance. Law enforcement notification for theft.
Report Losses on Operational Reports
Beer losses on Brewer’s Report of Operations (Form 5130.9). Wine losses through winery operational reporting. Distilled spirits losses on TTB Form 5110.28 or through DSP operational reporting.
Reconcile Losses in Federal Excise Tax Filings
Losses affecting tax determination reconcile in federal excise tax return filings. Form 5000.24 for federal excise tax. Adjustments where losses affect prior period tax determinations.
Preserve Loss Documentation for TTB Compliance Visits
Written loss records preserved under recordkeeping requirements support TTB compliance visits and audit response. Documentation trail supports defense of loss classification.
TTB Loss Reporting Compliance Layers

Book a DemoWhere TTB Loss Reporting Compliance Fails
Loss reporting failures cluster around undocumented losses, missed casualty notification, and reconciliation errors between operational reports and federal excise tax returns.
Undocumented Losses
Product losses not recorded in production records. TTB compliance visit reconciliation surfaces the gap.
Missed Casualty Notification
Fire, flood, or other casualty not promptly reported to TTB. Federal excise tax relief unavailable; compliance action risk.
Theft Response Gap
Product theft not reported to TTB or law enforcement. Federal excise tax exposure and compliance risk.
Reconciliation Errors
Losses on operational reports don’t reconcile with federal excise tax return. TTB audit flags the discrepancy.
Late Reporting
Losses reported late — either on operational reports or in required notifications. Timing compliance risk.
Excessive Evaporation Undocumented
Evaporation exceeding expected parameters without corresponding documentation or explanation. Unusual loss designation and potential federal excise tax.

TTB Loss Reporting — Frequently Asked
The angel’s share is the natural evaporation of distilled spirits during barrel aging. TTB recognizes angel’s share evaporation as a routine loss within accepted parameters under 27 CFR Part 19. Angel’s share is documented in DSP records and typically doesn’t trigger federal excise tax when within expected parameters.
Casualty losses from fires, floods, tornadoes, or other unexpected events; theft; and unusual losses that may affect federal excise tax determination require prompt TTB notification separate from routine operational reporting. Consult current TTB guidance on notification procedures.
Beer losses are reported on the Brewer’s Report of Operations (TTB Form 5130.9), which has a specific loss line item. Losses must reconcile with the beginning inventory plus production minus removals equation. Significant losses may require additional documentation or notification.
Wine losses are documented in winery cellar records under 27 CFR Part 24 and reported through the winery’s operational reporting. Bonded wine cellar losses have specific documentation requirements. Unusual losses may require additional notification.
Distilled spirits losses are documented in DSP records under 27 CFR Part 19 and reported through TTB Form 5110.28 (Distilled Spirits Losses) or through the DSP’s operational reporting. Angel’s share evaporation is typically routine; unusual losses require additional documentation.
TTB may provide federal excise tax relief on casualty losses in specific circumstances, but the relief requires timely notification, documentation of the casualty event, and typically confirmation that the product would have otherwise been tax-determined. Consult qualified tax counsel for specific casualty scenarios.
Evaporation exceeding expected parameters may be designated as unusual loss potentially triggering federal excise tax. Documentation of contributing factors (unusual warehouse conditions, extended aging periods) supports defensibility of the loss.
Theft requires immediate TTB notification and law enforcement engagement. Federal excise tax on stolen product may be due depending on circumstances. Documentation of the theft, investigation, and any recovery supports federal excise tax analysis and potential insurance claims.
Routine losses within accepted parameters generally don’t trigger federal excise tax. The tax determination point is critical — losses of product that had not yet reached tax determination typically don’t require tax payment on the lost quantity, provided the losses are within TTB’s accepted parameters.
Production records, cellar records, gauging records, transfer records, and casualty documentation preserved under the applicable 27 CFR part recordkeeping requirements. Written loss reports with date, quantity, cause, and witnessing personnel support defensibility.
Routine loss reconciliation follows the operational reporting cadence — quarterly or monthly Brewer’s Report of Operations for beer, winery operational reports for wine, DSP operational reports for spirits. Federal excise tax return reconciliation happens on the tax filing cadence.
Loss classification affects federal excise tax exposure. Consult qualified tax counsel when losses approach or exceed expected parameters. Documentation of contributing factors supports classification defensibility. TTB may inquire about excessive losses during compliance visits.
