High earners moving between US and Canada get blindsided by double taxation, foreign buyer taxes, RRSP contribution rules, and cross-border tax filing complexity — often losing $200K+ before realizing the financial impact
A web app where users input their income, assets (RSUs, investments, property), and destination province to get a personalized financial impact report showing effective tax rates, double-taxation exposure, hidden fees (foreign buyer tax, sales tax non-deductions), and estimated total cost of relocation vs. staying

The Reddit post describes losing $200K+ and 80+ hours of research. This is hair-on-fire pain with real dollar amounts. People don't lose $200K and shrug — they tell everyone. CRA fines for RRSP mistakes, foreign buyer taxes, departure tax surprises — these are financially devastating and emotionally scarring. The pain is acute, quantifiable, and occurs at a single decision point (the move), making it perfect for a one-time tool.
Narrow but deep. Roughly 300K-400K people cross the US-Canada border for work annually, but only a fraction are high earners with complex situations (RSUs, property, investments). Realistic addressable market is maybe 20K-50K people per year who would pay for this. At $99-299 average, that's $2M-$15M TAM. Not venture-scale, but excellent for a bootstrapped or small-team business. The niche is the feature, not the bug.
People currently pay $1,500-$10,000 for the same information from CPAs. A $99-299 digital report is 95% cheaper than the alternative. The pain signals show people losing $200K+ — paying $299 to avoid even 10% of that is a no-brainer. This is insurance-style pricing against a known, large financial risk. The anchor price (CPA consultation) makes your pricing look like a steal.
The UI and report generation are straightforward. The hard part is encoding accurate, up-to-date tax rules for 50 US states + 13 Canadian provinces, plus federal rules, treaty provisions, departure tax calculations, RSU vesting scenarios, and RRSP/401k cross-border treatment. A solo dev can build the MVP in 6-8 weeks IF they scope aggressively (e.g., start with CA/WA/NY → Ontario/BC only, W-2 income + RSUs only). The tax logic must be reviewed by a cross-border CPA — building this without one is a liability risk. Ongoing maintenance as tax law changes is non-trivial.
There is literally no self-serve, interactive tool that models the full tax impact of relocating between the US and Canada. The market is split between expensive advisory firms ($1,500+) with zero digital tools and tax filing software that cannot do planning or projections. The gap is enormous and obvious. Nobody has built a TurboTax-meets-NerdWallet for cross-border relocation. Every competitor is either too expensive, too generic, or too focused on filing rather than planning.
The core use case is a one-time decision (should I move? what will it cost?). Once someone moves and understands their situation, they don't need the calculator again. You could bolt on recurring value via annual cross-border tax optimization updates, ongoing filing coordination, or a community/advisory subscription — but the natural usage pattern is transactional. The $499 CPA-reviewed tier helps with revenue per user but doesn't create recurring revenue. This is more of a high-margin info product than a SaaS.
- +Extreme willingness to pay: people currently spend $1,500-$10,000 for this information, making $99-299 feel like a gift
- +Wide-open competitive gap: zero self-serve tools exist in this space despite clear, quantifiable demand
- +Pain is acute, specific, and has a natural viral loop (everyone who gets burned tells their friends/coworkers)
- +Content marketing goldmine: every tax pitfall is a blog post that ranks for high-intent search queries
- +CPA-reviewed tier ($499+) creates a high-margin upsell with defensible value
- !Regulatory/liability risk: if your calculator gives wrong advice and someone loses money, you could face lawsuits. Must have bulletproof disclaimers and CPA review for paid tiers
- !Tax law changes annually in both countries — ongoing maintenance burden to keep calculations accurate is real and non-negotiable
- !Market is niche: ceiling on growth without expanding to other country pairs (US-UK, US-Australia, etc.)
- !Seasonal demand spikes around tax season and corporate relocation cycles — uneven revenue
- !Building trust is critical: users are making six-figure decisions based on your output. Brand credibility takes time to build in financial services
