Pay-Sidekick
Built for what actually goes wrong
Generic salary calculators that gloss over province-specific brackets, CPP/EI ceilings, and partial-year deductions.
Multi-jurisdictional Canadian tax math kept up-to-date through 2024–2026 — Federal, provincial, and territorial brackets included.
Modelling variable pay (commissions, bonuses, overtime) and seeing how a one-time RRSP top-up actually moves your bottom line.
CRA-method RRSP planner and variable-pay simulator project month-by-month cashflow with payoff snowballing for installment debts.
What ships in the box
Multi-Jurisdictional Tax Engine
Federal, provincial, and territorial brackets through 2024–2026, with CPP and EI ceilings, basic personal amount, and provincial credits handled automatically.
CRA-Method RRSP Planner
Models contribution limits, carry-forward room, and the marginal-rate refund of a top-up so you can compare a payroll deduction vs. a lump-sum at year-end.
Variable Pay & Cheque Snowballing
Project commissions, bonuses, and overtime cheque-by-cheque, then snowball CRA installments and consumer debt against the resulting cashflow.
Built on enterprise-grade infrastructure
Pay-Sidekick is built around a private workspace — only you see your salary, deductions, and projected cashflow. Identity runs on Clerk (SOC 2 Type II, GDPR). All numerical data lives in a tenant-isolated D1 partition on Cloudflare's global network; no third-party analytics on the calculator pages.
Cloudflare global edge — innate DDoS protection, zero cold-starts.
Clerk (SOC 2 Type II, GDPR) for multi-tenant fleets; PBKDF2 for single-tenant apps.
