See the engine in action

Real numbers, not screenshots

These widgets call the same engine our paying customers use — federally accurate tax tables, all 13 provinces and territories, current to 2026.

SSAG + INDI

Tax-aware spousal support range with full Net Disposable Income split

Retroactive Arrears

Period-by-period chart that auto-splits at every CSG table version + min-wage transition

Numbers you can prove

The law, shown — not a black box you trust.

Every support number comes with the rule it came from. When a judge asks “why that number?”, you point at the page.

It shows its work
Every figure expands to the full line-by-line build-up — income, tax, child support, benefits — with the SSAG or Guidelines section printed beside each step. Nothing happens inside a box you can’t see.
Accurate where it’s math
Where the Guidelines give one right answer, it gives it — to the dollar, in every province and territory. The arithmetic is settled, and you can trace every cent of it.
Honest where it’s judgment
Where the law calls for judgment — high incomes, the ceilings and floors — it doesn’t pretend it’s arithmetic. It flags the call, cites the rule, and hands the decision to you.

Accurate to the dollar across all 13 provinces and territories — and every number cited to the published Guidelines, so you can explain it and defend it.

Built to keep the truth.

The system is filling up with confident, plausible, wrong answers — self-represented litigants run their facts through general AI and it invents case law and makes up numbers. You are the line that holds. Every figure here is grounded in the published Guidelines, cited to the section, and traceable end to end — not a guess dressed up as an answer, but the law, with the receipts.
