Free tools for the arithmetic that sits behind the most common cross-border tax questions. Each one runs the published rules on inputs you enter, cites its sources, and tells you what it doesn't cover. None of them are tax advice.
Estimate the deemed-disposition tax you would owe on leaving Canada. Enter your assets, see which ones are excluded (principal residence, RRSPs, pensions), and whether Form T1161 applies to your file.
Leaving CanadaCount your US days under the IRS weighted formula (current year + 1/3 prior + 1/6 the year before). See whether you meet the test and whether the Form 8840 closer connection exception keeps you a nonresident.
US residencyCompare the 25% Canadian withholding on a lump-sum RRSP withdrawal against the 15% treaty rate on periodic RRIF payments. Enter the plan value and see the yearly ceiling that keeps you at 15%.
RRSP drawdownFive questions, no dollar figures. Check which US catch-up path the published IRS criteria put you on: late FBARs only, delinquent information returns, Streamlined Foreign, Streamlined Domestic, or a conversation.
Catch-up filingEstimate the one-time 5% miscellaneous offshore penalty on Form 14654. Enter year-end foreign account balances for each covered year, see which year sets the base, and what the penalty would be.
Catch-up filingEvery calculator links to the full guide that explains the rules behind it. If you want the arithmetic run on your actual file rather than on round numbers, that is what the assessment is for.
The Cross-Border Assessment is a fixed $250. A dual-licensed CPA reads your specific situation and puts the answer in writing before you commit to anything bigger.
