If you trade across the 49th parallel, these are the questions Quinn answers and others ignore.
Cross-Border Arb Engine
FX-adjusted spread monitoring on 30+ MJDS dual-listed pairs (SHOP.TO/SHOP, RY.TO/RY, ABX.TO/GOLD). Get notified when spreads exceed 40 basis points so you can execute the trade.
W-8BEN Withholding Calculator
Quinn tells you exactly where to hold US-listed dividend payers: RRSP (0% withheld, treaty-exempt) vs TFSA (15% withheld, permanently lost). One toggle, instant guidance per ticker.
Superficial Loss Tracker
Canadian wash-sale equivalent (ITA s.54). Quinn warns when your repurchase falls inside the 30-day window so you don't accidentally lose a tax-loss harvest claim.
US Wash Sale Rule Check
For Canadian residents trading US-listed securities, Quinn applies IRC §1091 logic and flags wash sales before you trip them.
30 MJDS Cross-Listings
The Canadian-HQ issuers that file under the Multijurisdictional Disclosure System (most accessible TSX→US migration path) — Quinn keeps the live list curated.
Canadian Flow-Through Share Engine
CMETC, mining exploration deduction, METC stacking — Quinn calculates your true after-tax return on TSX-V mining juniors using flow-through-share treatment in your specific province.
RRSP vs TFSA Optimizer
Quinn analyzes ticker characteristics (US vs CA listing, dividend yield, expected capital gain) and recommends the most tax-efficient account in seconds.
T-Slip / 1099 Estimator
Predicts your T3, T5, T5008 (Canadian) AND 1099-DIV, 1099-INT, 1099-B (US) — useful for year-end tax-loss harvesting and capital gain crystallization.
One real scenario where Quinn saves you $1,500/year
You hold $50,000 of MSFT in your TFSA at 2.5% dividend yield.
That's $1,250/year in dividends. Most Canadians don't know:
❌ MSFT in TFSA
15% withheld by IRS at source. Permanently lost — TFSAs aren't recognized as pension accounts under the Canada-US tax treaty.
Net dividend: $1,062 instead of $1,250.
Annual leakage: $187.50 every year, forever.
✅ MSFT in RRSP (Quinn's recommendation)
0% withheld — treaty-exempt because IRS recognizes RRSP as a qualifying pension account.
Net dividend: $1,250.
Quinn saves you $187.50/year × 25 years compounding = $14,400+.
Multiply across all your US dividend holdings. Quinn pays for itself in the first month.
