Whatnot seller taxes: VAT, income tax & reporting (US, FR, UK, ES, IT…)

Direct answer: selling on Whatnot almost always creates two separate tax topics — (1) tax on the purchase (sales tax / VAT / GST, sometimes collected by Whatnot) and (2) tax on your profit (income tax, social contributions, CGT depending on country). A marketplace form (1099-K, DAC7) informs authorities; it does not replace your return or a licensed advisor.

This guide covers markets aligned with WhatCopilot (USD, EUR, GBP — Whatnot US & EU markets): United States, France, United Kingdom, Spain, Italy, Germany, plus Canada and Netherlands / Australia notes. Primary sources: Whatnot Help Center (country tax guides, tax collection, DAC7, 2025 1099-K), IRS, GOV.UK, French service-public / économie.gouv, European Commission. WhatCopilot is not affiliated with Whatnot and does not give personalised tax advice.

Buyer GMV, Whatnot net, taxable profit

Before countries, lock the vocabulary. On Whatnot, buyer_paid is what the buyer sees; transaction_amount in the Seller Weekly Orders Report is typically ledger net (commission, processing, and seller shipping usually already deducted). Neither is automatically “taxable profit”: you still need COGS, deductible expenses, and your local regime (Schedule C, micro-BIC, forfettario…).

What Whatnot collects at checkout (≠ your income tax)

Per Whatnot Help Center (“How tax is collected from purchases”), who collects tax at purchase depends on seller/buyer locations, shipment value, and the seller’s tax registration.

• US buyers: Whatnot generally charges applicable sales & use tax and remits it. Sellers (US or not) typically do not collect US sales tax on those orders.
• Canada: Whatnot collects applicable GST/HST/PST/QST on many sales into Canada (including elections for registered Canadian sellers).
• EU / UK (domestic sales): VAT-registered sellers are usually responsible for collecting and remitting VAT where registered. Prices are VAT-inclusive. Whatnot does not replace your registration duty.
• Import EU < €150 / UK < £135: Whatnot often collects import VAT at checkout; above threshold, VAT/duties are due on arrival.
• Australia / Japan: separate GST / JCT rules (local seller vs import) — see Help Center.

DAC7, UK & Canada: the platform reports your activity

Under DAC7 (EU Directive 2021/514), if you are an EU-resident seller and on Whatnot you exceed €2,000 in sales or 30 sales in a calendar year, Whatnot must report identity, TIN/VAT, quarterly totals, platform fees, etc. (via Whatnot Europe Limited / Ireland, then exchange). Annual cycle: year N data shared in January N+1. If you withhold required info, Whatnot may have to close the account or withhold payouts.

United Kingdom: UK seller data is reported to Irish authorities, then exchanged with HMRC. Canada (Part XX): excluded if < 30 sales and ≤ CAD 2,800; otherwise similar reporting (SIN / Business Number, totals, fees). Seller copy: Seller Hub → Finances → Statements & Reports → Digital Platform Reporting.

United States (USD): sales tax, 1099-K, Schedule C

Sales tax on the sale

For orders to US buyers, Whatnot generally collects and remits sales & use tax. That is not your federal income tax. Use Whatnot’s exemption flow if you hold a valid certificate.

Form 1099-K (tax year 2025+)

Per Whatnot (2025 1099-K article) and IRS 1099-K FAQs (post-OBBB): for third-party settlement organization payments, the federal reporting threshold is more than $20,000 in gross payments and more than 200 transactions. Both conditions apply federally. Whatnot issues via Stripe (connected Stripe account); forms are typically available by January 31 of the following year. Many states have lower thresholds (e.g. $600 in several states listed by Whatnot) — you may get a state-only 1099-K below the federal bar.

• Receiving a 1099-K ≠ “the whole amount is profit”: the form often reflects gross payments; deduct COGS, marketplace fees, shipping, etc. (e.g. Schedule C).
• No 1099-K ≠ tax-free: you still report taxable income from the first dollar of profit (IRC §61).
• Personal items sold at a loss: often no taxable income, but keep basis and sale evidence.

France (EUR): VAT, BIC / micro, capital gains

Whatnot’s France tax guide (January 2026) separates casual disposals vs professional activity, VAT, and social charges.

VAT and franchise en base

Standard rate commonly 20% (reduced rates by product). Goods franchise documented from 2025 / maintained in 2026: base threshold €85,000 (prior year), majoré €93,500 (current year) — service-public / économie.gouv and Whatnot guide. Services use lower thresholds (€37,500 / €41,250). Count all platforms.

• VAT-registered: VAT-inclusive prices, CA3 returns (often monthly; quarterly if annual VAT due < €4,000 per the guide).
• Add your French VAT number on Whatnot: reverse charge on Whatnot fees instead of Whatnot charging VAT on fees.
• B2C sales to other EU states > €10,000/year: buyer-country VAT, often via One Stop Shop (OSS).
• Second-hand margin scheme: VAT on the margin only — relevant for many collectors / resellers.

Income tax and social

Casual (not trading): movable capital gains (often exempt if sale price ≤ €5,000 per item, excluding precious metals and special cases) or flat tax on precious metals/objects. Regular resale: BIC (micro / actual / auto-entrepreneur — Whatnot cites ~€188,700 turnover caps for some micro rules as of January 2026). Register via Guichet unique; URSSAF for micro-social.

United Kingdom (GBP): VAT, Income Tax, NICs, CGT

VAT registration threshold (GOV.UK + Whatnot UK guide): taxable turnover more than £90,000 in 12 months, or you expect to exceed it in the next 30 days. Standard rate 20%. VAT-inclusive pricing when registered. Margin scheme (effective 16.67% on the margin) and Flat Rate Scheme (join if turnover ≤ £150,000 ex-VAT) exist for some profiles.

• Trading vs declutter: buying to resell is usually trading → Income Tax on profit + possible Class 4 NICs.
• £1,000 trading allowance: under that trading income, often no Self Assessment (exceptions exist).
• Personal allowance £12,570 (2024/25 and 2025/26 rates cited by Whatnot); tax year 6 April → 5 April; online Self Assessment typically due 31 January following.
• Outside trading: Capital Gains Tax may apply (£3,000 annual exempt amount for those years); rates/exemptions (e.g. items under £6,000) per HMRC.
• Northern Ireland: special VAT rules under the Protocol — Whatnot’s guide covers zero-rating / buyer import VAT.

Spain & Italy (EUR): IVA, autónomo / Partita IVA

Spain

Whatnot does not (as of writing) publish a Spain guide as detailed as FR/UK/DE, but EU rules apply: VAT-registered sellers collect/remit on domestic sales; VAT-inclusive EU prices; €10,000 distance-selling threshold + OSS; DAC7 if ≥ €2,000 or ≥ 30 sales. In practice many autónomos charge IVA from the first euro (no FR/DE-style SME franchise until local SME transposition is live — follow Agencia Tributaria). IRPF + autónomo social contributions on profit. E-invoicing / Verifactu rules are evolving — confirm with an asesor.

Italy

Same EU backbone (registration, OSS, DAC7). The forfettario regime (commonly cited ≤ €85,000 receipts, aligned with the EU SME cap) can simplify income tax and sometimes VAT handling — eligibility is strict (Agenzia delle Entrate). Partita IVA, codice fiscale, and compliant invoices remain central. For second-hand resale, check the margine (margin) scheme as elsewhere in the EU.

Germany, Netherlands, Canada (and other Whatnot markets)

Germany

Whatnot Germany guide + §19 UStG reform (2025): Kleinunternehmer if turnover ≤ €25,000 prior year and ≤ €100,000 current year (all platforms). No customer VAT under the scheme (reverse charge on Whatnot fees may still apply). Above: standard USt (often 19%), advance returns, annual return. Progressive income tax + possible trade tax (Gewerbesteuer) depending on activity.

Netherlands

Whatnot NL guide: same EU logic (€10,000 distance selling, OSS, reverse charge on fees). Small business: KOR (low national threshold, often cited around €20,000 — confirm with Belastingdienst). VAT returns often quarterly.

Canada

Whatnot Canada guide: for many deliveries into Canada, Whatnot collects and remits GST/HST/QST/PST. Federal + provincial income tax (Québec: two returns). Part XX reporting above CAD 2,800 or 30 sales.

Practical checklist before / during tax season

1. 1

   Clarify your status

   Casual declutter vs regular resale. That binary drives income tax, VAT, and social rules in almost every country above.

2. 2

   Complete Whatnot tax profile

   TIN / VAT / SIREN / NI number as required. Avoid DAC7 blocks and enable reverse charge on fees if registered.

3. 3

   Archive the ledger

   Seller Weekly Orders Report + Digital Platform Reporting. Keep buyer_paid, transaction_amount, refunds, COGS.

4. 4

   Watch thresholds in real time

   Franchise / VAT / Kleinunternehmer / 1099-K / DAC7 are annual (sometimes rolling). Do not look at Whatnot alone.

5. 5

   Separate checkout tax from profit tax

   Sales tax / VAT collected by Whatnot ≠ your personal or corporate income tax bill.

6. 6

   Get it validated

   CPA / tax advisor / asesor / commercialista — especially cross-border, metals, margin schemes, or multi-shop setups.
