Every company, key relationship, tax-program registration, and ownership structure in one place.
TaxDesk for multi-entity businesses
Five companies shouldn’t mean five tax systems.
TaxDesk gives Canadian corporate groups one permanent record of every entity, tax return, CRA obligation, tax balance, and ownership relationship — with external advisors working from the same information.

One corporation is manageable. Seven create a system problem.
The compounding problem
You started with one corporation.
Then came another location, a property company, a holding company, or an acquisition. The legal structure grew. The system underneath it stayed as folders, spreadsheets, inboxes, and memory.

One maintained record
The company owns the tax workspace.
Your finance team and the external advisors you invite work from the same group record. TaxDesk does not file returns or replace your accountant; it keeps the underlying corporate tax information connected and usable.
Know what’s due
See filings, payments, and upcoming tax obligations across the group.
Keep the tax history
Returns, CRA notices, tax attributes, and important facts remain attached to each entity year after year.
Work with your accountant
Invite external advisors to work from the same corporate tax record. Your company retains the workspace when people change.
Know what needs attention
Surface missing information, upcoming deadlines, unresolved records, and inconsistencies without reconstructing the group.
Corporate memory
Your tax record gets more valuable every year.
TaxDesk maintains a structured, source-backed history — not just a folder of PDFs. Facts remain connected to the return, notice, or document they came from, ready for human review.
