Poshmark Taxes 2025: Do You Owe? What $400, $600, and $2,500 Actually Mean

Sold on Poshmark in 2025? Here is what you owe for the 2025 tax year, filed in 2026.

Amber Liu started selling on Poshmark to clear out her closet. By month four, she was driving to thrift stores on weekends, buying to resell. By month eight, she had $11,000 in gross sales and a spreadsheet she'd stopped updating in June.

January arrived with a 1099-K from Poshmark showing $11,000. She googled the threshold, found $600, found $2,500, found $400, and couldn't figure out which number actually applied to her.

She owed more than she expected. She also could have deducted more than she did.

Amber's situation reflects what many Poshmark sellers experience when their casual selling becomes something more. Details are illustrative.

Three different dollar thresholds apply to Poshmark income in 2025. They mean three different things. Here's what each number actually does — and whether you owe anything.

The Three Numbers That Confuse Every Poshmark Seller

These are three separate rules with no direct connection to each other.

The 1099-K threshold ($2,500 for 2025) only determines whether you receive a form. It has nothing to do with whether you owe taxes.

The $400 threshold is the SE tax trigger — but it only applies if you're running a business, not selling personal items.

The actual tax question comes down to one thing: are you selling personal items you already owned, or are you running a reselling business?

Personal Items vs Business Sales: The Rule That Changes Everything

Selling Personal Clothes and Items You Already Owned

If you're selling your own clothes, shoes, bags, or other personal property:

At a loss (sold for less than you paid): No tax, no reporting required. Keep a record of your original purchase price in case the IRS asks about a 1099-K.

At a gain (sold for more than you paid): Taxable as capital gains. Short-term gain (owned less than 1 year): taxed at your ordinary income rate. Long-term gain (owned over 1 year): taxed at preferential capital gains rate (0%, 15%, or 20% depending on income).

Most personal clothing and household items are sold at a loss — you paid more at retail than you received on Poshmark. In those cases, no taxes apply.

Example: Bought a jacket for $180. Sold it for $45 on Poshmark. No tax owed — you sold at a loss.

Running a Reselling Business

If you're buying items specifically to resell — thrift stores, liquidation lots, garage sales, wholesale — you're operating a business. That means:

• Schedule C income (not just capital gains)
• Self-employment tax: 15.3% on net profit
• Federal income tax on top of SE tax
• All business expenses deductible (fees, shipping, supplies, mileage to sourcing trips)
• SE tax applies if net profit exceeds $400

Amber crossed from personal selling to business when she started buying inventory to resell. That transition has real tax consequences.

What Poshmark's 1099-K Shows — and Why It's Not Your Taxable Income

For 2025, Poshmark sends a 1099-K if your gross sales through their payment system exceeded $2,500.

What the 1099-K shows: Gross sales processed — before Poshmark's fees, before your cost of goods, before shipping. It's the total that went through their system.

What you report as income: Your actual revenue after Poshmark's fee. Then you subtract your cost of goods and other expenses to get net profit — which is what gets taxed.

The 1099-K is a reporting document. It doesn't determine your tax — your profit does.

Poshmark's Fee Structure — What's Deductible

Poshmark's fee structure changed in 2022 and applies to 2025 sales:

For business sellers: Poshmark's fees are a deductible business expense. If you sold $11,000 gross and paid $2,200 in fees, you report $11,000 as income and deduct $2,200 as a platform fee — or just report $8,800 net. Either approach produces the same taxable income.

For personal sellers: The fees reduce your net proceeds, which effectively reduces your taxable gain. If you sold a bag for $200 (original cost $350), Poshmark took $40 in fees — your proceeds were $160, and your loss is $350 − $160 = $190. Still a loss, still no tax.

If You're a Business Seller: How to Calculate What You Owe

Amber's 2025 tax calculation (reselling business, single filer, no other income):

At Amber's income level with proper deductions, she owed SE tax only — no income tax, because the standard deduction eliminated the remaining taxable income.

Without tracking her COGS ($3,200 in inventory purchases), she would have shown $8,450 in net profit instead of $5,250 — and owed $519 more in SE tax.

The SE tax formula for Poshmark sellers:

1. Net Schedule C profit × 92.35% = SE tax base
2. SE tax base × 15.3% = SE tax owed
3. SE tax × 50% = deduction from gross income (reduces income tax)

What Business Poshmark Sellers Can Deduct

Cost of Goods Sold (COGS)

The biggest deduction most resellers miss or miscalculate. COGS is what you paid for the items you sold.

Beginning inventory (Jan 1)
+ Purchases during the year
− Ending inventory (Dec 31)
= Cost of Goods Sold

If you bought $3,200 in inventory and sold all of it, COGS is $3,200. If you have $400 worth sitting unsold at year-end, COGS is $2,800 — the items you actually sold.

Platform Fees

Poshmark's 20% fee (or $2.95 flat) on every sale — fully deductible as a business expense.

Shipping Costs

Poshmark provides prepaid labels and builds shipping into its pricing structure, but if you pay for additional packaging materials (poly mailers, tissue paper, boxes, tape), those are deductible.

Mileage

Trips to thrift stores, estate sales, liquidation centers, and the post office count as business miles. At $0.70/mile in 2025, 1,000 sourcing miles = $700 deduction.

Supplies

Label printers, scale, poly mailers, tissue paper, hangers, mannequins, lighting for photos, a backdrop — anything bought specifically for the business.

Phone (Business Percentage)

If you use your phone for Poshmark activity — photographing items, communicating with buyers, managing listings — the business-use percentage of your monthly bill is deductible.

Home Office

If you dedicate a space exclusively to your Poshmark business — a spare room used for photography, sorting, and shipping — the simplified method allows $5 per square foot, up to 300 sq ft.

The Hobby vs Business Distinction

What if you're somewhere in the middle — buying to resell, but inconsistently, and not sure if it's a "real" business?

The IRS presumes you're running a business if you earned a profit in at least 3 of the past 5 years. For newer sellers, that presumption doesn't apply automatically.

IRS factors for hobby vs business:

• Do you keep records?
• Do you depend on the income?
• Do you try to improve profitability?
• Have you made a profit in some years?
• Do you operate in a businesslike manner?

Why it matters:

• Hobby: Can't deduct losses against other income. Expenses limited to income amount. Report on Schedule 1, not Schedule C.
• Business (Schedule C): Full deduction of losses, expenses, COGS. SE tax applies on net profit.

Sellers who buy inventory specifically to resell are almost always operating a business, not a hobby.

What If You Received a 1099-K But Were Just Clearing Out Your Closet?

If you receive a 1099-K but you were selling personal items at a loss, you still need to address it on your return — the IRS receives a copy of the 1099-K and will notice if it doesn't appear on your return.

How to handle it:

1. Keep receipts or records showing your original purchase price for each item
2. Report the 1099-K gross amount as income on Schedule D
3. Subtract your cost basis (original purchase price) to show the loss
4. Net loss: no tax owed

If you don't have records for older items, estimate conservatively — a $40 shirt you wore for two years is worth less at resale than what you paid. The IRS expects personal items to be sold at a loss, and a documented loss is your protection.

Quarterly Taxes for Poshmark Resellers

If your Poshmark business is expected to produce $1,000 or more in annual tax, the IRS requires quarterly estimated payments.

2025 Quarterly Deadlines:

For Poshmark sellers with consistent monthly sales, set aside 25–30% of net profit (after fees and COGS) each month and pay quarterly. Sellers with seasonal peaks can adjust based on actual income each quarter.

Frequently Asked Questions

Do I owe taxes on Poshmark sales under $2,500?

Possibly. The $2,500 threshold only determines whether Poshmark sends you a 1099-K. If you're running a business and your net profit exceeds $400, SE tax applies regardless of whether you received a form. Personal item sales at a loss are generally not taxable at any amount.

What if I received a 1099-K for sales that were all personal items I sold at a loss?

You still need to account for the 1099-K on your return. Report the gross amount and then show your cost basis (what you paid originally) to demonstrate there was no gain. Keep purchase records. The loss should reduce your taxable income to zero on those sales.

Is Poshmark taxed differently than eBay or Mercari?

The tax treatment is the same — the platform doesn't change whether you owe taxes. What matters is whether you're selling personal items or running a business, and whether you made a profit. The 1099-K threshold is the same for all three platforms in 2025 ($2,500).

Can I deduct Poshmark sales that resulted in a refund or return?

Yes. If a buyer returned an item and you refunded them, that transaction shouldn't appear in your net sales. If it's included in your 1099-K gross, report it as income and deduct the refund as a business expense on Schedule C.

Do I need a business license to sell on Poshmark?

Poshmark doesn't require one. Tax treatment as a business doesn't require a formal business license either — the IRS classifies activity as a business based on intent and practice, not registration. That said, some states require a seller's permit for sales tax purposes; check your state's rules.

What's the best way to track inventory for Poshmark taxes?

A spreadsheet works for most sellers. Track each item: date purchased, cost, date sold, sale price, fees. This gives you COGS automatically and makes tax time straightforward. For higher-volume sellers, apps like Vendoo or List Perfectly include basic bookkeeping alongside listing management.

Amber now tracks every thrift store trip, every purchase price, every payout. January tax prep takes her an afternoon. Her COGS spreadsheet told her exactly what she paid for what she sold — and the deduction it produced was larger than the 1099-K stress that started her filing season.

The three thresholds still confuse people. The underlying question is simpler: did you make a profit, and was this a business? Answer those two, and the rest follows.
