Income Tax and Cottage Food: What You Need to Know

There is no cottage food exemption from federal income tax. The state laws that allow you to sell food made in your home kitchen govern food safety and permitting — they say nothing about your federal or state tax obligations. Every dollar of revenue from sales at farmers markets, online orders, or direct customer sales must be reported as business income on your federal return.

For most cottage food producers operating as sole proprietors — the default legal structure when you haven't formed a separate business entity — business income and expenses are reported on Schedule C, "Profit or Loss from Business," which is filed as part of your personal Form 1040. Your net profit (revenue minus allowable deductions) from Schedule C flows directly into your total taxable income for the year. If you've formed an LLC (limited liability company), the default tax treatment for a single-member LLC is also Schedule C; the LLC structure affects your legal liability exposure but doesn't change how you're taxed unless you've elected a different tax classification.

If you've formed a multi-member LLC or partnership with a co-owner, your business would file a separate partnership return (Form 1065), and each partner receives a Schedule K-1 showing their share of income and loss to report on their personal return. S-corporations and C-corporations are separate tax entities entirely and are rarely the right choice at the cottage food revenue level, but a tax professional can walk you through the options if your business is growing significantly.

Keep your business income separate from personal income to the greatest extent possible. Even if you haven't opened a dedicated business bank account, maintaining a separate tracking spreadsheet or simple accounting software entry for every sale and every business expense will make Schedule C preparation far less painful — and far more accurate.

The most straightforward deductions for cottage food businesses are direct product costs: the ingredients you purchase to make your products. Flour, butter, sugar, eggs, specialty chocolates, extracts, nuts — anything that goes into or onto your baked goods is a cost of goods sold (COGS) deduction. So is packaging: boxes, bags, clamshells, labels, stickers, twist ties, tissue paper.

Track every grocery run and packaging supplier order; save your receipts. The IRS requires substantiation for business deductions, and "I estimated how much I spent on flour" doesn't hold up in an audit.

Market and selling fees are fully deductible. Farmers market booth fees, annual market membership fees, online marketplace fees, credit card processing fees, and any commission you pay on sales all reduce your taxable income. If you pay for a market-specific permit or insurance certificate, those costs are deductible as well.

Business-related mileage is often one of the largest overlooked deductions for cottage food producers. Every trip to the grocery store specifically for business ingredients, every drive to the farmers market and back, every run to pick up packaging supplies — the miles driven for business purposes are deductible at the IRS standard mileage rate (which fluctuates annually; check the current rate on IRS.gov). Use a mileage tracking app on your phone or a dedicated logbook to record the date, destination, business purpose, and miles for every business trip. Don't rely on memory.

Other potentially deductible expenses include: business-specific equipment purchases (a stand mixer used exclusively for your cottage food business, for example), a portion of your internet cost if you use it to manage orders or market your business, advertising costs (social media ads, business cards, a website), professional fees (accounting or legal fees related to the business), and bank fees on a dedicated business account. If you take business-related classes or buy books on food safety, baking techniques, or business management, those education expenses may be deductible as well.

The home office deduction is one of the most valuable and most misunderstood deductions available to home-based business owners, and cottage food producers occupy a complicated position with respect to it. The IRS requires that to claim the home office deduction, you must use a specific portion of your home "regularly and exclusively" for business. For a home baker, this creates a genuine challenge: your kitchen is also used to prepare meals for your family.

The IRS has historically been strict about the "exclusive use" requirement for the kitchen itself. However, cottage food producers may be able to claim a home office deduction for a dedicated space used exclusively for business purposes — a home office where you manage orders, do bookkeeping, package products, or handle customer communications, for example — even if the kitchen doesn't qualify. If you have a basement area or a portion of a room used exclusively for business storage, packaging, or order management, document it carefully.

For the workspace that qualifies, you can calculate the deduction using either the simplified method ($5 per square foot of dedicated space, up to 300 square feet) or the regular method (the actual percentage of your home's square footage devoted to business use, applied against actual home expenses like mortgage interest or rent, utilities, insurance, and repairs). The regular method typically yields a larger deduction but requires more documentation. Your tax professional can help you determine which approach makes sense given your specific home and business situation.

Even if your kitchen doesn't qualify for the home office deduction, you may still be able to deduct a portion of utilities directly attributable to your baking production — particularly electricity and gas — under a different expense category, using usage logs to substantiate the business portion. This is an area where working with a tax professional who has experience with home-based food businesses can pay for itself many times over.

Self-employment tax is one of the most significant and surprising tax obligations for new cottage food producers. When you work as an employee, your employer withholds Social Security and Medicare taxes (together called FICA) from your paycheck and matches those contributions.

When you're self-employed, you pay both the employee and employer portions yourself — a combined rate of 15.3% on net self-employment income (12.4% for Social Security on income up to the annual wage base, plus 2.9% for Medicare with no cap). This is in addition to your regular federal and state income tax on the same income.

The self-employment tax is calculated on Schedule SE and added to your total tax liability for the year. One silver lining: you can deduct half of your self-employment tax as an adjustment to income on your Form 1040, which slightly reduces your taxable income. This deduction happens above the line, meaning you don't need to itemize to claim it.

Because self-employed individuals don't have an employer withholding taxes throughout the year, the IRS requires you to pay estimated taxes quarterly if you expect to owe $1,000 or more in federal taxes for the year. Estimated tax payments are due four times annually — typically in April, June, September, and January — and cover both income tax and self-employment tax. Missing or underpaying estimated taxes can result in a penalty when you file your annual return.

A simple approach: each time you make a sale deposit, set aside 25 to 30% of your net profit in a separate savings account earmarked for taxes. When quarterly payment dates arrive, send in what you've accumulated or consult your prior year's tax liability to calibrate the right payment amount. Most accounting software can calculate estimated tax payments automatically based on your income entries throughout the year.

Sales tax on food is a state-level issue with no uniform national rule, and the rules are more varied and complex than most cottage food producers realize. Many states exempt food products — including baked goods — from sales tax entirely, treating them as groceries.

Others tax prepared food or food sold for immediate consumption but exempt packaged shelf-stable items. A few states tax all food.

Some states have different rules depending on where you sell (at a farmers market vs. directly to a consumer vs. online). Your state's Department of Revenue or Taxation website is the authoritative source; look specifically for guidance on "food and food products" sales tax treatment in your state.

If your state requires you to collect sales tax on your cottage food sales, you'll need to register with the state tax authority, collect the appropriate rate from customers, file periodic sales tax returns, and remit the collected tax to the state. Failing to collect required sales tax doesn't relieve you of the liability — the state can hold you responsible for uncollected amounts. Most accounting software and point-of-sale systems designed for small businesses can handle sales tax collection and reporting automatically once you configure the correct rates.

State income tax on cottage food income follows roughly the same framework as federal income tax in most states: your net Schedule C profit is taxable income, subject to state income tax rates and subject to estimated payment requirements at the state level as well. A handful of states have no income tax, which simplifies things considerably.

As for when to hire an accountant: if your cottage food income exceeds $10,000 in a year, or if you're navigating home office deductions, significant equipment purchases, or the transition from sole proprietor to LLC, professional tax help almost always pays for itself. A CPA or enrolled agent with experience in small food businesses or self-employment can identify deductions you'd miss, help you avoid costly mistakes, and set up systems that make future years easier. Even a single session to review your tax situation and set up a tracking system can be worth the cost.
