3D Printing Taxes for US Sellers: What You Actually Need to Know (2026)
US tax for 3D print sellers has two main layers: sales tax (state-level, triggered by economic nexus) and self-employment/income tax (federal + state). This guide covers both without the accountant jargon. Link to free calculator for cost tracking.

| State income tax | You | 0–13.3% | Depends on state |

Self-employment tax — the one most sellers miss
When you sell as a sole trader/freelancer in the US, you pay both the employee AND employer share of Social Security and Medicare: 15.3% total on net profit. This is before income tax. On $20,000 net profit: ~$3,060 in SE tax alone. Budget for this from day one.
What counts as a deductible expense
Filament, printer purchase (depreciation or Section 179 expensing), electricity (home office %), packaging, Etsy fees, software subscriptions, shipping supplies, and a proportion of your internet bill if used for business. Keeping receipts and tracking costs with a tool like LayerMath directly reduces your taxable profit.
Sales tax and economic nexus
Most states require you to collect sales tax once you exceed $100,000 in sales OR 200 transactions in that state in a calendar year. If you only sell on Etsy, Etsy handles this automatically in 45+ states under Marketplace Facilitator laws — check your Etsy Payment account to see what Etsy has collected on your behalf.
Quarterly estimated taxes
If you expect to owe more than $1,000 in federal tax for the year, the IRS expects quarterly estimated payments (April, June, September, January). Missing these triggers an underpayment penalty. A rough rule: set aside 25–30% of every sale for taxes.
When to get an accountant
If your 3D printing income exceeds $10,000/year, an accountant who understands Schedule C filing is worth the cost. The deductions they find typically outweigh their fee.
The single most important habit: track every cost. Filament, electricity, packaging — all of it. Your taxable profit is revenue minus expenses. LayerMath calculates your costs per print; that data is also your tax record.
