Watch out for

Your 1099-K reports gross sales before cancellations, refunds and Poshmark's commission, so it will be higher than what you redeemed.
Secondhand items sold for less than you paid aren't taxable income, so keep records of what you originally paid to back out those sales.
Poshmark collects and remits sales tax on top of the buyer's price; it isn't taken from your earnings and isn't your income.
Several states have lower 1099-K thresholds than the federal rule, and the state list can change from year to year.

Federal rules for 2026

Entity choice changes your taxes

A single-member LLC is taxed like a sole proprietorship unless it elects S-corp status. The S-corp can lower payroll tax but adds payroll, a separate return and a reasonable-salary requirement.

Retirement as a tax lever

With no employees, a Solo 401(k) allows up to $72,000 in 2026. With employees, a SEP IRA or a 401(k) must generally cover eligible staff too.

Quarterly estimated taxes

No one withholds tax from self-employment income, so you generally pay estimates four times a year if you expect to owe $1,000 or more. For 2026 income the federal dates are April 15, June 15 and September 15, 2026, and January 15, 2027. Paying 100% of last year's tax (110% if your AGI was over $150,000) in four equal installments avoids the underpayment penalty.

Self-employment tax

On top of income tax, self-employed people pay 15.3% on 92.35% of net profit: 12.4% Social Security up to the 2026 wage base of $184,500, plus 2.9% Medicare with no cap. Half of it is deductible.

A worked example

A solo founder with $200,000 of profit in 2026
Self-employment tax as a sole proprietor	$28,234
Solo 401(k) maximum as a sole proprietor	$61,677
Payroll tax saved as an S-corp on a $100,000 salary	$12,934
Solo 401(k) maximum as that S-corp	$49,500
