You just finished your first year selling handmade goods. You have a shoebox of crumpled receipts, three different bank statements, and a vague sense of dread about filing taxes. Sound familiar?
Here's the good news: small business tax record-keeping isn't complicated. The IRS doesn't expect you to be an accountant. They expect you to keep reasonable records that support what you claim on your tax return. That's it.
Here's exactly what to keep, how long to keep it, and the simplest system for staying organized — even if you're running your business from a spare bedroom.
What the IRS Actually Requires
The IRS says you need to keep records that support your income and expenses. Specifically, they want to see:
- Gross receipts — proof of the money your business brought in (sales records, bank deposits, receipt books)
- Purchases — proof of what you bought to make or resell products (supplier invoices, credit card statements)
- Expenses — proof of costs you're deducting (rent, utilities, subscriptions, mileage)
- Assets — records for big purchases like equipment, computers, or vehicles used for business
The key word is proof. You need documentation that backs up every number on your Schedule C. A bank statement showing a $47 charge at Michaels isn't enough on its own — you also need the receipt showing what you bought, because not everything at Michaels is a business expense.
Receipts You Should Keep for Every Deductible Expense
If you're deducting it, you need a receipt for it. Here are the categories most small product-based businesses deal with:
Materials and Supplies
Every purchase of raw materials, packaging, labels, and shipping supplies. This is usually your biggest expense category. Save the receipt from every trip to your supplier, every online order confirmation, every wholesale invoice.
Shipping Costs
Postage, USPS receipts, UPS/FedEx invoices, shipping label purchases. If you use a service like Pirate Ship or Stamps.com, download your monthly or yearly reports — those count as records.
Platform and Software Fees
Etsy listing fees and transaction fees, Shopify subscription, payment processing fees, any order management or accounting software you use. Download your annual fee summary from each platform. Etsy, for example, provides a downloadable CSV of all fees charged in a given year.
Home Office
If you work from home, you can deduct a portion of your rent or mortgage interest, utilities, and internet. The simplified method lets you deduct $5 per square foot of your dedicated workspace, up to 300 square feet ($1,500 max). Keep a record of your workspace measurements and your lease or mortgage statement.
Vehicle and Mileage
Trips to the post office, craft store, and markets count. You have two options: track actual expenses (gas, maintenance, insurance — proportional to business use) or use the standard mileage rate ($0.70 per mile for 2025). Either way, keep a mileage log with the date, destination, purpose, and miles driven. A note on your phone calendar works fine.
Marketing and Advertising
Facebook and Instagram ad spend, business cards, market booth fees, website hosting. Save invoices and billing summaries.
Professional Services
If you pay someone to do your taxes, take product photos, or build your website, keep those invoices. Also save any business license or permit fees.
How Long to Keep Everything
The short answer: keep tax records for at least three years from the date you file the return. That's the standard IRS audit window.
But there are exceptions:
- Six years if you underreported income by more than 25% (you probably didn't, but why risk it)
- Seven years if you claimed a loss from worthless securities or bad debt
- Indefinitely if you didn't file a return or filed a fraudulent one
The practical advice: keep everything for seven years and do not think about it again. Digital storage is basically free. Set up a folder on your computer or Google Drive called "Tax Records" with subfolders for each year, and you're covered.
The Simplest Organization System
You don't need QuickBooks. You don't need a filing cabinet. Here's a system that takes about 10 minutes a week:
Step 1: Photograph Every Paper Receipt Immediately
The second you get a paper receipt, take a photo with your phone. Receipts fade. They get lost. They go through the wash. A phone photo taken in the parking lot of the craft store is worth more than a pristine receipt you can't find eight months later.
Save the photos to a dedicated folder on your phone or a cloud service. Name them with the date and store if you have time ("2026-01-15-Michaels.jpg"), but even unnamed photos in a "Receipts 2026" folder are better than nothing.
Step 2: Create Simple Folders
On your computer or Google Drive, create this structure:
- Tax Records 2026
- Materials & Supplies
- Shipping
- Software & Fees
- Home Office
- Mileage
- Marketing
- Other Expenses
- Income Records
Once a week — pick a day, maybe Sunday evening — move your receipt photos into the right folders. It takes five minutes.
Step 3: Track Income in One Place
Your income records should come from your sales platform (Etsy, Shopify, your own website) or your order management tool. If you're using something like OrderHelm to track orders, your sales data is already organized by date and amount — just export it at year-end. If you're tracking sales manually, a simple spreadsheet with columns for date, item, quantity, and amount works fine.
Step 4: Download Annual Summaries in January
Every January, download your yearly summaries from every platform you use: Etsy's annual CSV, Shopify's financial reports, PayPal's transaction history, your bank's annual statement. Save them in your Tax Records folder for that year. These are your backup if any individual receipt goes missing.
Common Mistakes That Cost You Money
Not Tracking Small Purchases
That $3.50 roll of packing tape at the dollar store is deductible. So is the $7 parking fee at the farmers market. These small expenses add up to hundreds of dollars over a year. If your business generates $30,000 in revenue and you miss $800 in small deductions, you're paying taxes on money you actually spent on the business. At a 22% tax bracket, that's $176 in extra taxes for no reason.
Mixing Personal and Business Spending
If you use one credit card for everything — groceries, business supplies, date nights, shipping labels — sorting out your business expenses at tax time becomes a nightmare. Open a separate bank account or credit card for business purchases. Many banks offer free business checking accounts. This single step cuts your tax prep time in half.
Forgetting About the Home Office Deduction
If you have a room or area in your home used regularly and exclusively for business, you qualify. A 10x12 foot spare bedroom used as your workshop is 120 square feet. At $5 per square foot, that's a $600 deduction you might be leaving on the table.
Waiting Until April
Spending 10 minutes a week on receipts is easy. Spending an entire weekend in April trying to reconstruct a year's worth of expenses from memory and bank statements is miserable and inaccurate. You'll miss deductions, make mistakes, and hate the whole process. The weekly habit is worth it.
When to Get Professional Help
If your business revenue is under $20,000 and your expenses are straightforward, you can probably handle your own taxes with software like TurboTax Self-Employed or FreeTaxUSA. Once you're above $30,000-$40,000, or if you have employees, inventory accounting questions, or multi-state sales tax obligations, hiring a CPA or enrolled agent is money well spent. Expect to pay $200-$500 for a small business tax return, and yes — that fee is deductible.
The most important thing is to start keeping records now, even imperfectly. A messy folder of receipt photos is infinitely better than nothing. You can always improve your system later. You can't go back in time and recreate receipts you threw away.
