The Illusion of Gross Profit

Michael, an investment banker in New York, proudly sold his Rolex Submariner for $38,000 after purchasing it for $18,000 three years ago. On paper: a clean $20,000 profit. His actual take-home after the 28% collectibles tax, sales platform fees, authentication costs, and currency exchange? Just $6,300.

Three months later, Michael rolled his next piece into an S-Corp, harvested equity losses, and cleared $12,400—double the after-tax profit on a smaller headline gain.

Jurisdiction-by-Jurisdiction Tax Treatment

The tax bite varies dramatically depending on where you sell

United States

Luxury watches are taxed as “collectibles” at 28% for long-term capital gains (IRS Code § 408(m))

Plus 3.8% Net Investment Income Tax for high earners

Plus state taxes (California’s top 13.3% applies on top slice of income)

Online platforms must report gross watch sales exceeding $5,000 in 2024, dropping to $2,500 in 2025

According to KPMG partner Elizabeth Chen, “We’re seeing a 300% increase in collectibles audits as the 1099-K thresholds drop and automated matching improves.”

Canada

Watches are “Listed Personal Property” (jewellery category)

50% of the gain is included in income and taxed at your marginal rate

The $1,000 “floor rule” deems both cost and proceeds ≥ $1,000, eliminating small gains/losses

Canada Revenue Agency treats watches differently from standard capital property

United Kingdom

Watches qualify as “chattels”

Sales with gross proceeds ≤ £6,000 are exempt from capital gains tax

Above that threshold, gains are taxed at 10%/20% or 18%/24%, depending on income bracket

The CGT annual allowance has dropped to £3,000 for 2024/25

HMRC guidelines specify special rules for valuable chattels

EU-resident sellers

National CGT rates vary (0–34%)

Sale is taxed where you are a resident

DAC7 now forces platforms to share seller data with all EU tax authorities

Three Border Surprises No One Mentions

1. VAT/Sales Tax Recapture Issues

When purchasing in Switzerland or France (20–22% VAT), EU residents cannot reclaim it. Tourists can theoretically get ~12% back at export, but the paperwork and border controls often negate this benefit.

2. Import Duty Traps

U.S. residents enjoy a duty-free allowance up to $800, with a flat 4% from $800 to $1,800. UK residents re-importing a watch purchased abroad face 20% VAT plus 2–4% duty if the watch was not “in free circulation” when it left.

3. Cross-Border Resale Requirements

Selling a Daytona to a buyer in another country now classifies you as a “merchant” under various reporting regimes. Without proper VAT/EORI numbers, your shipment risks being impounded.

Cross-border transactions trigger reporting in both jurisdictions—plan accordingly.

Five Structuring Moves That Work in 2025

Corporate or Trust Ownership

In Canada, a Canadian-controlled private Corporation can flow the non-taxable half of capital gains out as a capital dividend. U.S. collectors using an S-Corp may avoid the 3.8% NIIT if owners materially participate.

Equity Loss Harvesting

U.S. collectors should consider offsetting 28% collectible gains with stock losses, as these losses aren’t “quarantined” to specific asset classes.

Cost Basis Optimization

Regular qualified appraisals and meticulous record-keeping of all service invoices can establish a higher cost basis, reducing taxable gain.

Ownership Splitting

In the UK, inter-spouse gifts are CGT-free. Two separate £6,000 sales can effectively double the low-value exemption.

Digital Provenance Files

Maintain comprehensive digital records: purchase invoice, customs entry, service records, and timestamped photos.

Strategic planning before purchase can double your after-tax return.

Collector’s Quick Checklist

✔️ Document everything: date, cost, taxes, FX rate, servicing, transport

✔️ Insure and formally appraise every three years

✔️ Obtain export documentation when buying abroad

✔️ Verify marketplace tax settings—update your taxpayer ID

✔️ Budget realistically: 12–18% of sale price for costs in the U.S.; 18–25% in Canada, UK, and most EU states

✔️ Consult a cross-border tax adviser before your first five-figure transaction

1099-K Threshold Timeline

Year 1099-K Reporting Threshold Trend

2024 $5,000 ↓

2025 $2,500 ↓

2026 $600 ⚠️

Virtually all online watch transactions will be visible to tax authorities by 2026. The IRS has confirmed these thresholds are now locked in per the Tax Reporting Modernization Act.

Looking Forward: 2025–2027

1099-K threshold drops to $2,500 in 2025 already law.

The EU VAT-rate directive implementation may increase standard rates in multiple countries, with Slovakia already raising VAT from 20% to 23% in 2025.

Phillips Auctions’ latest fee schedule confirms seller’s premiums now average 12% on watches over $100,000, up from 10% in 2023—another quiet cost increase.
