Reseller tax planning after COGS, mileage, and self-employment tax
This calculator estimates reseller taxable income for the period you enter after revenue, buyer shipping, COGS, platform fees, seller-paid shipping, supplies, mileage, home office, phone/internet, SEP contribution, self-employment tax, and a selected income-tax bracket.
For 2026 mileage, the tool splits business miles between the IRS Jan. 1-June 30 business rate of 72.5 cents per mile and the July 1-Dec. 31 business rate of 76 cents per mile.
The 1099-K watch input uses the current IRS threshold of more than $20,000 and more than 200 transactions, but taxable business income still needs to be tracked whether a form arrives or not.
- Best for monthly reserves, per-flip tax planning, and deciding how much cash to set aside.
- Uses IRS self-employment tax structure, simplified home-office cap, split 2026 mileage rates, self-employed SEP effective-limit estimate, and 1099-K threshold checked on 2026-08-06.
- Planning estimate only; filing status, state tax, inventory accounting, wage-base limits, and mixed-use expenses can change the final return.

Frequently Asked Questions
How does the reseller tax deduction calculator work?
Enter one consistent period of gross sales, shipping charged to buyers, COGS, platform fees, shipping you paid, supplies, mileage, home-office, phone/internet, and optional retirement contributions. The calculator estimates Schedule C-style net income, self-employment tax using the IRS 15.3% Social Security and Medicare rate structure, income tax at your selected bracket, and an estimated quarterly set-aside when the inputs are annual totals.
What deductions can resellers claim on Schedule C?
Common reseller expenses include COGS, platform fees, payment processing, shipping labels, packing supplies, business mileage, storage, a qualifying home office, business-use phone and internet, software, and subscriptions. Keep receipts, mileage logs, and a clear business purpose for each deduction. Ask a tax professional before claiming ambiguous or mixed-use expenses.
How does Form 1099-K affect reseller tax reporting in 2026?
The IRS says Form 1099-K reporting has reverted to the more than $20,000 and more than 200 transaction threshold under current law, though processors can still send a form at lower volumes. A reseller must report taxable business income whether or not a 1099-K arrives, so use the form as a reconciliation document rather than the only source of truth.
How much is self-employment tax for resellers?
The IRS self-employment tax rate is 15.3%, made up of 12.4% Social Security and 2.9% Medicare, applied through the self-employment tax calculation on net earnings. This calculator estimates the common 92.35% net-earnings adjustment, but your final liability can change with filing status, other income, credits, and annual wage-base limits.
Can I deduct reselling tools and subscriptions on Schedule C?
Software, apps, subscriptions, pricing tools, photo tools, bookkeeping tools, and marketplace research services can be deductible when they are ordinary and necessary for the resale business. Keep the receipt, renewal date, and business-use explanation, especially if the tool is also used personally.
