You report every sale as business income on your federal return, whether the customer paid in cash, by card, or through an app. Farmers market vendor taxes are income tax and self-employment tax on your profit, quarterly payments once you expect to owe enough, and sales tax where your state taxes what you sell.

Do I have to report cash, card and app sales from the market?

Yes, you report all cash, card and app sales on your federal return, whether or not any form arrives. IRS Publication 334 says business income includes cash, checks and credit card charges, including income no payor reports to you on a 1099.

If customers pay you directly by credit, debit or gift card, the processor sends you a Form 1099-K, the form that reports card and app payments to you and the IRS, no matter how few payments you took or how small the total, per the IRS 1099-K page. A payment app sends a 1099-K for 2026 only if your payments for goods and services exceed $20,000 and come through more than 200 transactions. 1099-K card and app sales share the same gross receipts as cash, reported once. Money from friends and family as a gift or personal repayment is not income.

For cash, Publication 583 asks you to keep a daily summary of cash sales, deposit the day's receipts in your business account, and keep the deposit slips. A receipt book or a dated end-of-day cash count serves as that summary.

How is farmers market income taxed on my federal return?

A sole proprietor's market income is taxed as profit on Schedule C, the form for a one-owner business's profit or loss, per the Schedule C instructions. Gross receipts, meaning everything customers paid you before costs, go on line 1, and your costs come off to leave net profit. If your main income is raising crops, the Schedule F instructions put farm income on Schedule F instead of Schedule C.

You also pay self-employment tax, the Social Security and Medicare tax on your own business profit. Self-employment tax for 2026 is 15.3%, made up of 12.4% Social Security on earnings up to $184,500 and 2.9% Medicare, figured on 92.35% of your net profit, meaning your profit after costs, per the IRS self-employment tax page. It applies when that 92.35% figure, your net earnings from self-employment, is $400 or more, and half of it is deducted in figuring your adjusted gross income.

In this hypothetical, the $11,082 of net earnings (92.35% of $12,000) is over $400, so self-employment tax applies, and the 2026 tax comes to about $1,696.

What can I deduct for booth fees, ingredients and a canopy?

Booth fees, ingredients, packaging and small equipment are deductible when they are ordinary and necessary, meaning common in your line of work and helpful to it, per Publication 334. A booth or stall fee is deductible, and I treat it as rent of business property on Schedule C because rent is a payment for the use of property you do not own. The same guide lists licenses and regulatory fees as deductible. An expense that is partly personal has to be split, and only the business part counts.

Ingredients and packaging that go into what you sell are cost of goods sold, meaning what you spent making the items you sold, figured in Part III of Schedule C. For the canopy, table and cooler, the de minimis safe harbor is an IRS election to deduct items costing $2,500 or less per item or invoice in the year you buy them. You attach a statement titled "Section 1.263(a)-1(f) de minimis safe harbor election" to a timely filed return and deduct the amounts in Part V, Other Expenses, per the IRS tangible property FAQ and the Schedule C instructions. A cart or generator that costs more than $2,500 is not covered and is depreciated, or written off by a section 179 or bonus depreciation election, under the food cart equipment rules instead.

Do I have to charge sales tax at a farmers market?

It depends on your state and on what you sell, because sales tax is state law. The SBA's state tax page tells sellers to check their state's Department of Revenue, and the same check applies to pop-up vendor sales tax at fairs and events, so do it before the season starts.

On the federal return, sales tax imposed on you as the seller is a deductible tax on Schedule C line 23, per the Schedule C instructions. If you collected that tax from buyers, the amount collected also goes into gross receipts on line 1.

Do I need to pay quarterly estimated taxes?

Yes for 2026 if you expect to owe $1,000 or more after withholding and refundable credits. You are not required to pay if your withholding and credits cover at least 90% of your 2026 tax or 100% of your 2025 tax (110% if your 2025 adjusted gross income, or AGI, was over $150,000). Estimated tax is payments you send the IRS during the year when no tax is withheld, and the last 2026 payment on Form 1040-ES is due January 15, 2027.

You can skip the January 15, 2027 payment if you file your 2026 return by February 1, 2027 and pay the entire balance with the return. If a payment is short or late, the penalty runs on each underpayment for the number of days it stays unpaid.

If you live in California, do you need a seller's permit for a farmers market?

Yes if what you sell is taxable, because a seller's permit is a state registration to sell taxable items. In California, a vendor selling at one location for under 90 days needs a temporary seller's permit, per CDTFA's home-based business guide. Three or more swap meets, flea markets and special events in 12 months require an ongoing permit. The permit is free, per CDTFA Publication 73.

The permit depends on what’s taxable. CDTFA's guide treats hot prepared food as taxable, while cold food to go and baked goods sold to go are generally not taxable. A vendor selling only cold food to go needs no permit unless they sell where admission is charged, sell carbonated or alcoholic drinks, or provide tables and chairs, per CDTFA Publication 111. Craft sellers need the permit because crafts are ordinarily taxable goods.

"I work as vendor in San Bernardino CA. I don't have an tax ID but I do have a sellers permit what tax code do I use?"

That vendor, posting on the TurboTax Community in 2021, was asking about two separate systems. The seller's permit is the state sales tax registration, separate from the federal return. Federally the vendor still files Schedule C and enters on line B the six-digit code from the business activity code list in the Schedule C instructions that matches what they sell.
