We’ve seen this pattern dozens of times.
A winery owner hands us their books. Everything looks clean. Sales tax is filed. Excise tax is paid. They’re confident they’re compliant.
Then we ask: “Where are you tracking use tax on your complimentary wine?”
Blank stare.
Most winery owners don’t realize that free tastings trigger tax obligations. When you pour wine without charging for it, you become the consumer of that bottle. And consumers pay tax.
The issue isn’t just the wine itself. It’s the bottles, corks, labels, and packaging materials that went into producing that “free” pour. According to California compliance guidance, wineries pay tax on free wine and taxable items purchased for resale that are given away without charge.
This is one of the most commonly overlooked tax obligations in the wine industry. And it’s expensive when you get it wrong.
Where Complimentary Wine Creates Tax Liability
Use tax obligations pop up in places most wineries never think to look.
Wine club tastings. You’re building loyalty and retention, but every complimentary bottle you open for members creates a use tax obligation on the packaging components.
Trade tastings and distributor events. When you send your sales team to pour at restaurants or retail shops, you’re giving away product. The state expects you to track it and pay use tax on the materials.
Staff consumption and samples. That bottle you opened for the tasting room team to taste before a shift? That’s taxable too.
Promotional giveaways. Buy-one-get-one offers are particularly tricky. Many wineries run these promotions without realizing they must pay use tax on the free item and remit it to the state. A simple wording change like “Buy 2 and get 50% off the total” can eliminate the exposure entirely.
The pattern we see is this: wineries focus on sales tax because it’s visible and direct. Use tax is invisible until an auditor shows up asking why you haven’t been paying it.
How to Calculate What You Actually Owe
Calculating use tax on complimentary wine isn’t complicated, but it requires tracking systems most wineries don’t have in place.
Here’s what you need to measure:
Cost of packaging materials per bottle. This includes bottles, corks, labels, capsules, and any chemicals incorporated into the wine. You’re not taxed on the wine itself when it’s complimentary, but you are taxed on everything that makes it a finished product.
Volume of complimentary wine distributed. How many bottles did you pour at tastings? How many did you give to trade partners? How many went to staff or were used for samples?
Your local use tax rate. This varies by jurisdiction, so you need to apply the correct rate for where the consumption occurred.
The formula is straightforward: packaging cost per bottle × number of complimentary bottles × applicable use tax rate.
The problem isn’t the math. The problem is that most wineries don’t have systems that capture this data in real time.
We recently worked with a winery that discovered it had been underreporting use tax for three years. They were pouring 200+ complimentary bottles per month at their tasting room and had no system to log them. When we built out the tracking and calculated their exposure, it was over $18,000 in back taxes.
That’s the cost of not having documentation practices in place.
Documentation Practices That Survive Audits
When CDTFA auditors show up, they’re looking for proof.
They want to see that you tracked every complimentary bottle, calculated use tax correctly, and remitted payment on time. If you can’t produce documentation, they’ll estimate your liability based on your sales volume. And their estimates are never in your favor.
Here’s what we recommend:
Create a complimentary wine log. This should capture the date, number of bottles, purpose (tasting room samples, trade event, staff consumption), and the packaging cost per bottle. Assign someone on your team to maintain this log daily.
Reconcile your log against inventory monthly. When your annual physical inventory reveals a shortage of bottled wine, the TTB requires you to report it and pay wine excise tax on the shortage. Missing bottles from tastings or shrinkage create real tax obligations.
Separate complimentary wine from sales in your accounting system. Don’t bury it in cost of goods sold or miscellaneous expenses. Create a dedicated account so you can track it clearly and calculate use tax accurately.
Keep receipts for all packaging materials. You need to prove what you paid for bottles, corks, and labels. If you didn’t pay sales tax at purchase, you owe use tax when you use those materials for complimentary wine.
Document the purpose of each distribution. California law presumes that all wine removed from a bonded winery has been sold in the state unless you can prove otherwise. That means the burden of proof is on you to show that complimentary distributions were legitimate and properly taxed.
We’ve seen wineries lose tens of thousands of dollars in audits because they couldn’t produce this documentation. The tax liability was real, but the penalties and interest made it worse.
Common Compliance Mistakes We See Repeatedly
Most compliance failures aren’t intentional. They’re the result of not understanding how the rules apply to your specific operations.
Assuming tasting room samples are exempt. Some wineries believe that samples poured on bonded premises don’t create tax obligations. That’s partially true for federal excise tax if you keep proper records, but it doesn’t eliminate state use tax on packaging materials.
Treating promotional displays as marketing expenses. If you create a display for a retail partner and don’t sell it to them, you’re the final consumer. If you didn’t pay sales tax when you purchased the display materials, you must report and pay use tax.
Failing to track trade tastings in other states. When you send sales reps to host tastings or participate in festivals outside California, you can create a physical nexus in those states. That means additional compliance obligations beyond just the California use tax.
Not adjusting for inventory shortages. Shrinkage happens. Bottles break. Staff consumes product. But if you can’t account for missing inventory, auditors will assume it was sold without tax being collected.
Using spreadsheets instead of integrated systems. We’ve worked with wineries tracking inventory in three different spreadsheets. They were missing cases, losing product, and had no idea why cash felt tight. When accounting, inventory, and production data live in separate systems, compliance gaps are inevitable.
What Happens When You Get It Wrong
The consequences of use tax noncompliance aren’t abstract.
Audits result in back taxes, penalties, and interest. Depending on how long the noncompliance went undetected, you could be looking at a six-figure liability.
But the financial cost isn’t the only risk. Not following tax rules and regulations can lead to the loss of your license. For wineries, compliance isn’t optional. It’s essential to continue operating.
We’ve seen auditors dig into three years of records, reconstruct complimentary wine distributions from tasting room logs and event calendars, and calculate use tax owed based on estimated packaging costs. The winery had no documentation to dispute the findings.
The bill was $73,000.
That’s what happens when you don’t have systems in place.
Building Systems That Keep You Compliant
Compliance doesn’t have to be complicated, but it does require intention.
You need systems that capture data at the point of distribution. You need processes that reconcile complimentary wine against inventory. And you need someone who understands winery-specific tax obligations to review your books regularly.
Here’s what that looks like in practice:
Integrate your tasting room POS with your accounting system. When staff log a complimentary tasting, it should automatically create a record that feeds into your use tax calculation.
Build use tax into your monthly close process. Don’t wait until year-end to calculate what you owe. Review complimentary distributions monthly, calculate use tax, and accrue the liability on your balance sheet.
Train your team on documentation requirements. Your tasting room staff and sales reps need to understand why tracking complimentary wine matters. If they don’t log it, you can’t calculate tax on it.
Work with someone who specializes in winery accounting. Generalist accountants don’t know the nuances of TTB regulations, CDTFA compliance, or how to structure wine costing. You need someone who speaks the language and understands the industry.
We work exclusively with wineries because the compliance requirements are specific and the stakes are high. When we rebuild a winery’s books, we’re not just cleaning up transactions. We’re building systems that capture the data you need to stay compliant and avoid expensive surprises.
What to Do Next
If you’re reading this and realizing you have gaps in your compliance, start here:
Audit your current practices. How are you tracking complimentary wine? Do you have documentation that would survive a CDTFA audit? Can you calculate the use tax owed for the past 12 months?
Build a complimentary wine log immediately. Even a simple spreadsheet is better than nothing. Start capturing the data today, so you’re not trying to reconstruct it later.
Review your accounting systems. Are complimentary distributions properly classified? Is the use tax being calculated and accrued? Are your books set up to support winery-specific compliance requirements?
Talk to someone who specializes in winery accounting. If you’re unsure whether you’re compliant, get a second opinion from someone who knows the regulations and has seen what auditors look for.
At Llamas Financial, we work with wineries to clean up their books, build compliant systems, and eliminate the kind of tax exposure that keeps owners up at night.
