1

Total gross sales (all platforms)

eBay + Etsy + Poshmark + other

$12,000 + $0 + $0 + $0

= $12,000

This is what your 1099-Ks will show in aggregate. Your taxable income is after deductions.

2

Platform fees

~13% estimated rate on gross sales

$12,000 × 13%

= $1,560

Use your actual seller hub fee reports for accuracy — the auto-estimate is a rough average across platforms.

3

Total deductions

COGS + platform fees + shipping/packaging + other expenses

$4,000 + fees + $800 + $400

= $6,760

IRC §162 (ordinary business expenses) + IRC §1221 (inventory/COGS)

4

Taxable reseller profit

total gross sales − total deductions

$12,000 − $6,760

= $5,240

5

Self-employment tax

profit × 0.9235 × 0.153

$5,240 × 0.9235 × 0.153

= $740

IRC §1401; IRS Schedule SE

6

AGI (adjusted gross income)

profit + W-2 + other income − SE deduction

$5,240 + $0 + $0 − $370

= $4,870

7

Federal income tax (on taxable income)

AGI − standard deduction → marginal brackets

$4,870 − $14,600 = $0 taxable

= $0

8

Net tax owed (after withholding)

federal income + SE + state − W-2 withholding

$0 + $740 + $0 − $0

= $740

9

Quarterly estimated payment

net owed ÷ 4

$740 ÷ 4

= $185

Due April 15, June 15, September 15, January 15.

IRS Form 1040-ES

10

Set-aside rate per dollar of gross sales

net owed ÷ total gross sales

$740 ÷ $12,000

= 6.2% of every dollar you collect

Transfer this percentage of each sale to a separate savings account. You will always have your tax payment ready.

Key insight

The most important number for a reseller isn't the tax bill — it's the set-aside rate per sale. Once you know what percentage of every transaction to save, quarterly taxes become automatic. Track your COGS as you buy, pull your fee reports quarterly, and you will never have a Hayden moment.
