Who we are
Larivco & Cie was built to solve a recurring cross-border challenge: unexpected Canadian withholding tax that disrupts projects, payroll, and cash flow. Too often, non-residents from the US, UK, France, and Germany discover late in the process that Canada may require withholding on services (Regulation 105), employment income (Regulation 102), or certain Canada-source payments (Part XIII / NR4)—and that compliance can quickly become complex.
We’re a boutique firm dedicated to making Canadian withholding rules practical and manageable. We combine 15+ years of experience with tax advisory leadership, bringing both technical depth and real-world execution. We support companies and individuals with withholding exposure reviews, compliant withholding and remittance workflows, waiver and reduction requests (R105, R102-R), RC473 non-resident employer certification, NR4/Part XIII compliance, and, where relevant, NR5/NR6 withholding reduction filings—always with an audit-ready mindset.
