Looking for International Tax Accountant for US/Canada Dual Citizen - Recommendations?
Title: Looking for International Tax Accountant for US/Canada Dual Citizen - Recommendations? 1 I'm planning a move from Toronto to Seattle in a couple of months and need to find a good tax accountant who understands both US and Canadian tax systems. As a dual citizen, I'm already struggling with filing taxes in both countries every year, and now with this cross-border move coming up, I'm completely lost. I've been researching online and found firms like Thompson & Associates and McMillan Tax Services that specialize in cross-border situations, but reviews are really mixed. Some people love them, others say they're overpriced and not responsive. I'd especially appreciate someone who can advise on my retirement accounts (I have a 401(k) from when I previously worked in the US and a growing RRSP here in Canada) and help me understand the tax implications of moving assets between countries. Has anyone worked with a good cross-border tax specialist that they would recommend? Personal experiences would be super helpful!

7 I've been handling US/Canada dual taxation for about 8 years now, and it's definitely complicated! A good cross-border accountant is worth their weight in gold. I worked with Fitzgerald International Tax when I moved from Vancouver to Boston. Their specialty is exactly this kind of situation - they have experts licensed in both countries who understand all the cross-border implications. They helped me navigate the departure tax in Canada, foreign tax credits, and how to properly report my Canadian retirement accounts to the IRS. For your retirement accounts specifically, be careful - there are special reporting requirements for foreign accounts (FBAR and FATCA), and there are specific treaties that affect how RRSPs are taxed by the US. A mistake here can be costly! Make sure whoever you choose has specific experience with US/Canada situations, not just "international" tax - the treaties between our countries have unique provisions that general international tax people sometimes miss.

•12 Do you know approximately how much they charged for their services? I've heard these cross-border specialists can be really expensive. Also, did they help with state taxes too? I'm moving to California which I've heard has its own complications.

•7 Fitzgerald charged me about $1,200 for the first year which included all the extra forms for the move itself. Subsequent years have been around $800 annually. It's definitely more than a simple return would cost, but considering the complexity and potential penalties for mistakes, I've found it worthwhile. Yes, they handled my state taxes too. Each state has different rules, and California does have some unique tax situations. Make sure you ask specifically about state-level issues when interviewing potential accountants. Many people focus on the federal/country level and forget that states can have their own complex rules.

15 After struggling with cross-border tax issues for years, I finally found help through taxr.ai (https://taxr.ai) and it's been a game-changer for my situation. I'm also a dual US/Canadian citizen who moved from Montreal to Chicago a few years ago. What I love about their service is they did a complete analysis of my previous filings and found several cross-border deductions I'd been missing. They also helped me understand how the US-Canada tax treaty actually works in practical terms - turns out I was double-paying on some income unnecessarily! They specialize in analyzing complex tax situations like yours where you have retirement accounts in both countries. Their document review tool was especially helpful for making sense of all the paperwork from both countries. Saved me hours of sorting through statements.

•18 I'm in a similar situation but moving from Boston to Toronto. How do they handle the complexity of Canadian provincial taxes alongside US state taxes? And did they give you guidance on timing your move to minimize tax impact? I've heard the date you officially become a resident can make a huge difference.

•4 I've seen a few of these AI tax services popping up lately. Do they have actual CPAs who understand the US-Canada tax treaty? My situation involves property in both countries plus retirement accounts, and I'm worried an automated system might miss something important.

•15 They handle provincial and state taxes really well actually. They have specialists who know the specific rules for each province and major US states. For my Quebec-to-Illinois move, they outlined exactly how the different provincial and state credits worked together. And yes, they gave me specific advice on timing my move - suggested moving in January rather than November as it would simplify my tax year. They're not just an automated system - they have actual accountants with cross-border expertise who review everything. The AI part helps organize and identify issues, but real CPAs who specialize in US-Canada situations do the analysis and provide recommendations. For my property and investment accounts, they had specific strategies I hadn't considered.

18 Just wanted to follow up that I decided to try taxr.ai after our conversation, and I'm really glad I did. They identified that my previous accountant had been incorrectly reporting my RRSP contributions on my US returns, which could have caused problems down the road. They also showed me how to properly time exchanging currency to minimize tax impacts when moving funds between countries. The best part was their clear explanation of how the foreign tax credit works between US and Canada - I finally understand how to avoid double taxation! They provided a detailed document explaining my specific situation that I can reference whenever questions come up. Definitely recommend them for anyone dealing with cross-border tax issues.

9 If you're dealing with the IRS for any past filing issues (which often happens with dual citizens), I highly recommend using Claimyr (https://claimyr.com) to actually get someone on the phone. When I moved back to the US from Toronto, I had some FBAR filing issues I needed to resolve quickly. After wasting days trying to get through to the IRS myself, Claimyr got me connected to an actual IRS agent in under 45 minutes. You can see how it works in their demo video: https://youtu.be/_kiP6q8DX5c. My issue required talking to a specific international tax department at the IRS that was nearly impossible to reach directly. Their service navigated the phone tree and wait times, then called me when an agent was on the line. Saved me literally hours of hold music and frustration.

•3 How exactly does this work? Do they just sit on hold for you? I've been trying to reach the IRS about my FBAR forms for weeks with no luck. Seems too good to be true that someone could actually get through when the lines are always "experiencing higher than normal call volume.

•21 I'm skeptical. The IRS international taxpayer line is notoriously understaffed. I spent 3+ hours on hold last month and still got disconnected. If this actually works, it would be worth almost any price, but I have a hard time believing anyone has some magic solution to the IRS phone system.

•9 Yes, they essentially wait on hold so you don't have to. They have a system that monitors the hold and navigates the phone menus, then calls you when a real person answers. You don't need to keep your phone line open or sit there listening to hold music. I understand the skepticism - I felt the same way! The IRS international line is absolutely terrible. What I think happens is they're calling continuously throughout the day and have figured out the patterns of when calls are more likely to get through. When they get someone, they connect you. It's not magic, just clever use of technology and persistence. They can't guarantee a specific wait time, but in my experience and from what I've heard from others, it's consistently much faster than trying yourself.

21 I have to eat my words here. After my skeptical comment, I decided to try Claimyr out of desperation since I needed to resolve my foreign account reporting issue before a deadline. I was connected to an IRS international tax specialist in about 57 minutes, which is miraculous compared to my previous attempts. The agent was able to help me sort out confusion about reporting requirements for my Canadian TFSA account on US tax forms. Got confirmation that my approach was correct and now have peace of mind that I won't face penalties. Never thought I'd be recommending a service for calling the IRS, but if you're struggling with international tax issues and need to actually speak to someone, it's absolutely worth it.

5 One specific thing to consider: if you're moving to Ottawa, find someone who understands Ontario provincial tax alongside federal Canadian tax. I made the mistake of using a US-based "international" accountant who didn't fully understand provincial differences and ended up having to file amendments. Also, don't forget about the exit tax implications when you leave the US. Depending on your assets, there could be deemed disposition rules that apply. My accountant caught this and saved me a significant amount by planning the timing of my move and certain asset sales.

•14 What's this about an exit tax? I'm planning to move to Vancouver next year and nobody mentioned anything about this. I thought I just needed to file a final US return and then start filing Canadian returns. Is there something else I need to be aware of?

•5 The exit tax primarily affects US citizens who are renouncing citizenship, or green card holders who are giving up permanent residence. If you're maintaining your US citizenship, you'll still need to file US tax returns even after moving to Canada - the US taxes based on citizenship, not residency. What I was referring to are the tax implications of changing residency. When you become a Canadian resident, Canada considers you to have "acquired" your existing assets at fair market value, which establishes your cost basis for future Canadian tax purposes. The US has different rules that can apply when you move investments or retirement accounts across the border.

11 Having gone through this exact situation (moving from California to British Columbia), my advice is to interview at least 3 different cross-border specialists before deciding. Ask these specific questions: 1. How do they handle FBAR and FATCA reporting requirements? 2. What strategies do they recommend for RRSPs and 401(k)s in a cross-border situation? 3. What's their experience with the foreign earned income exclusion and foreign tax credits? 4. How do they stay current with changes to the US-Canada tax treaty? I ended up going with a smaller firm that specializes exclusively in US-Canada situations rather than a big international firm that does all countries. The specialized knowledge made a huge difference.

•23 Do you think it's even possible to DIY this stuff with tax software? I've been using TurboTax for my US returns and SimpleTax for Canadian, but I'm moving to the US next month and wondering if I should just bite the bullet and pay for a professional.

•I wouldn't recommend DIY for cross-border situations, especially in your first year of moving. The tax software you mentioned (TurboTax and SimpleTax) aren't designed to handle the complexities of dual filing requirements, foreign tax credits, and treaty provisions between the US and Canada. I tried to do it myself initially and made several costly mistakes - missed foreign tax credit opportunities, incorrectly reported my Canadian retirement accounts, and didn't properly handle the timing of my residency change. The penalties for errors on international forms can be severe, and the IRS is particularly strict about foreign account reporting. For your first year, I'd strongly recommend getting professional help to establish the proper framework. Once you understand how everything works together, you might be able to handle simpler years yourself, but that initial transition year is just too complex to risk doing wrong.

I went through a similar cross-border move (Toronto to Denver) about 3 years ago and can share some hard-learned lessons. The biggest mistake I made was waiting until tax season to find an accountant - by then, all the good cross-border specialists were swamped and I ended up with someone who wasn't as experienced. Start your search now, even before you move! A good cross-border accountant can actually help you plan the timing and structure of your move to minimize tax implications. For example, they might recommend which month to establish residency, how to handle any stock options or bonuses, and whether to liquidate certain accounts before or after the move. Also, ask about their fee structure upfront. Some charge a flat fee for cross-border moves, others bill hourly. I found that firms charging flat fees were more motivated to be efficient, while hourly billing sometimes led to unnecessarily complex approaches. One more tip: make sure they can handle both your final Canadian return (with departure tax calculations) AND your partial-year US resident return for the same tax year. Not all international tax preparers are comfortable with both sides of this equation.

•This is excellent advice about starting early! I'm actually in the planning phase right now (move isn't until spring) so this timing tip is really valuable. Can you elaborate on what you mean by "departure tax calculations"? I keep seeing references to various tax implications when leaving Canada but I'm not clear on what specific calculations or forms are involved. Also, did your accountant help you with any pre-move planning around timing of income or asset sales? I'm definitely going to start interviewing specialists now rather than waiting. The flat fee vs hourly billing insight is particularly helpful - I hadn't thought about how that might affect their approach to the complexity of the situation.

•Great question about departure tax! When you cease to be a Canadian resident, Canada treats it as if you've sold all your assets at fair market value on your departure date - this creates a "deemed disposition" for capital gains purposes. You don't actually sell anything, but you may owe tax on any unrealized gains. There are some exemptions (like your principal residence and certain retirement accounts), but things like non-registered investment accounts, rental properties, etc. can trigger significant tax bills. The good news is you get a "step-up" in cost basis for Canadian tax purposes if you ever return. My accountant definitely helped with pre-move planning. We timed my departure for early January to keep my high-income year fully in the US (better tax rates), and I sold some losing positions before leaving Canada to offset gains from the deemed disposition. We also looked at whether to contribute to my RRSP before leaving (spoiler: we didn't, as it would complicate US reporting). The planning aspect is where a good cross-border specialist really earns their fee - the actual tax return preparation is just documenting decisions you should have made months earlier!
