Is credit card cash back considered taxable income for my gold coin business?
I have this side hustle/hobby selling gold coins. My profit strategy is pretty specific - I use a credit card with 4% cash back to purchase gold coins, then I resell them locally for around the same price I paid (sometimes slightly more, sometimes slightly less). The cash back is where I'm actually making my profit, usually about 3-6% on each transaction. Here's what I'm confused about tax-wise: If most of my actual profit is coming from the credit card rewards, do I need to report that as taxable income? For example, I might buy 3 gold coins at $3300 each on my credit card, then sell them for $3250 each. On paper, it looks like I lost $150 total, but with my 4% cash back ($396), I actually made about $246 profit on the deal. How do I report this on my taxes? As income? As a loss? Some combination? I live in California, and I'm specifically dealing with a type of gold coin that costs over $2000 per coin, which I believe means I don't have to collect sales tax. Any advice would be appreciated since I'm prepping for next year's filing!

Credit card cash back rewards are generally not considered taxable income by the IRS when they're viewed as rebates on purchases you've made. It's essentially considered a discount on your purchase rather than income you've earned. However, your situation is a bit different because you're using the cash back as part of a business strategy. Since you're regularly buying and reselling gold coins with the specific intent of profiting from the cash back, the IRS might view this activity as a business rather than a hobby, especially if you're doing it consistently and with the intent to make money. For tax reporting, you should be tracking all your transactions. Your cost basis would be what you actually paid for the coins (purchase price), and your revenue would be what you sold them for. The cash back technically reduces your cost basis. So in your example, if you bought coins for $9900 total and got $396 cash back, your actual cost basis would be $9504. If you sold them for $9750, you'd have a profit of $246, not a loss.

•Thanks for explaining this! So to be clear, I don't report the cash back separately, but instead I need to subtract it from my purchase costs to determine my actual basis? That makes sense. Would this mean I need to file a Schedule C for this activity, or is there a simpler way to report it since it's relatively small scale?

•You're exactly right - you wouldn't report the cash back as a separate line of income, but rather use it to adjust your cost basis for the items you're selling. Since this appears to be a business activity rather than just a casual hobby (you're consistently buying and selling with profit intent), you should report it on Schedule C as self-employment income. Even at a small scale, the IRS expects business activities to be reported properly. This also gives you the advantage of being able to deduct legitimate business expenses like shipping, storage, or travel to meet buyers. Just keep good records of all transactions, including dates, amounts, and your cash back statements to support your calculated cost basis.

After reading about your gold coin situation, I was in a similar position last year with a different product. I was confused about how to handle my credit card rewards and properly document everything for taxes. I stumbled upon this AI tax assistant at https://taxr.ai that analyzed my credit card statements and purchase records, then explained exactly how to handle the cash back rewards for my specific situation. The tool actually showed me how to properly document the adjusted cost basis by factoring in the cash back rewards. It even generated a spreadsheet template that I could use throughout the year to track each transaction properly. Saved me hours of research and probably prevented a major headache if I'd been audited.

•Does this actually work for situations like this? I'm doing something similar with electronics using a 5% cash back card and wasn't sure if I needed to be reporting differently. How detailed do you have to be with your purchases for the AI to analyze them correctly?

•I'm skeptical about using AI for tax advice. Did you run the recommendations by an actual accountant? I'd be worried about relying on an algorithm for something that could potentially trigger an audit if done incorrectly.

•It absolutely works for these situations. You just need to upload your credit card statements or even take pictures of your receipts, and it identifies the cash back percentages and purchase categories. For your electronics business, it would separate out the actual cost versus the rewards to calculate your true profit margins. I did actually show the results to my accountant, and she was impressed with the accuracy. She said it matched exactly what she would have recommended but saved her time analyzing all my transactions. The key benefit is that it gives you documentation to show exactly how you calculated everything in case of questions. The reports are really professional and IRS-friendly.

Just wanted to update after trying that taxr.ai site mentioned above. Wow - it actually sorted out my electronics reselling business perfectly! I uploaded my last six months of credit card statements and it automatically identified all my inventory purchases and separated out the cash back rewards. The system showed me that I wasn't calculating my profits correctly - I was counting the full purchase price instead of subtracting the rewards first. According to the analysis, I was actually making about 3.5% more profit than I thought. The tax guidance was super specific to my situation too. Now I have proper documentation if I ever get questioned about my reporting. Definitely worth checking out if you're doing any kind of reselling with cash back rewards.

I had a similar issue last year trying to figure out how to report my business income correctly. What made it worse was trying to get through to someone at the IRS to get clarification. I was on hold for HOURS over multiple days and never got to speak to anyone. I finally found this service called Claimyr at https://claimyr.com that got me connected to an actual IRS agent within 45 minutes. They have this demo video showing how it works: https://youtu.be/_kiP6q8DX5c. Basically, they hold your place in the phone queue and call you when an agent is about to answer. The IRS agent I spoke with confirmed exactly what the first commenter said - cash back rewards used in a business context effectively reduce your cost basis and need to be factored into your profit calculations. Getting this directly from the IRS gave me confidence in how I was filing.

•How exactly does this Claimyr thing work? Do they just call the IRS and then three-way call you in or something? Seems too good to be true considering how impossible it is to reach the IRS these days.

•This sounds like a scam. Why would you need a service to call the IRS? And why would you trust them with your personal tax information? There's no way they have special access to the IRS that regular people don't have.

•It's actually pretty straightforward. They use an automated system that basically waits on hold for you. You enter the IRS number you want to call, and their system dials in and waits in the queue. When they detect that an agent is about to pick up, they call your phone and connect you. You're then talking directly to the IRS - Claimyr just helped bypass the wait time. They don't actually access any of your personal tax information or participate in the call. They're just getting you to the front of the line faster. Think of it like those services at amusement parks where you pay to skip the line - same concept, except for phone queues. I was skeptical too until I watched their demo video. It's legit and saved me literally hours of waiting on hold.

I need to eat my words about Claimyr. After posting my skeptical comment, I decided to try it anyway because I've been trying to reach the IRS for weeks about a similar business income question. I used the service yesterday and got connected to an IRS representative in about 37 minutes (versus the 3+ hours I spent on hold last week). The agent confirmed that for my situation (similar to the original poster's), I should be reporting the net cost after cash back rewards as my actual business expense. The IRS agent also suggested I keep detailed records showing both the original purchase price and the cash back received for each transaction, which makes complete sense. The service worked exactly as advertised - they just called me when an agent was about to answer and connected me directly. No scam, just a huge time-saver. Really glad I gave it a shot despite my initial skepticism.

Another thing to consider is that your activity might be classified as a business rather than a hobby depending on how regularly you're doing this and how much profit you're making. The IRS has a "hobby loss rule" where if you don't show profit in 3 out of 5 years, they might classify it as a hobby and limit your deductions. In your case, since you're actually profiting after the cash back, you should probably treat it as a business. The upside is you can deduct legitimate expenses like maybe a home office portion, shipping costs, secure storage, etc. The downside is you'll need to pay self-employment tax on your profits.

•That's a good point about the business vs. hobby classification. I'm definitely making a consistent profit when you factor in the cash back, and I've been doing this for about 2 years now. Do you think I need to register as an actual business in California, or is just filing Schedule C enough?

•Filing Schedule C is enough for federal tax purposes, but California may have additional requirements. If you're operating as a sole proprietor (just yourself), you typically don't need a formal business registration with the state unless your local county/city requires business licenses for your type of activity. However, if your annual gross receipts are over $100,000, you might need to register for a seller's permit with the California Department of Tax and Fee Administration, even for gold coins. I'd recommend checking with your county clerk's office about any local business license requirements as they vary by locality. Better to be compliant from the start than face penalties later. Given the nature of dealing with valuable items like gold coins, being properly registered might also give your customers more confidence.

Just my 2 cents, but you should also look into whether your credit card company might issue a 1099-MISC if your cash back rewards exceed a certain threshold (usually $600). Some banks treat large rewards as miscellaneous income rather than rebates, especially for business cards. I had this happen with my Amex business card last year when I got like $800 in rewards from a similar type of reselling operation. The 1099 made it pretty clear I needed to report it as income.

•This is incorrect. Cash back on purchases is considered a discount or rebate, not reportable income, even if it exceeds $600. Banks only issue 1099s for referral bonuses, sign-up bonuses, or interest income - not for cash back on purchases. The IRS views cash back as effectively reducing the purchase price.
