Karbon vs TaxCycle (2026): which should you pick?

Pick Karbon if

• Fits if you run an accounting firm and want shared client email and workflow in one place
• Makes sense if your firm already works in Gmail and Google Calendar

Look elsewhere if

• Not for you if you want software for your own books, as it's built for firms
• Skip it if you want to try it yourself first, because there's no self-serve trial
• Pricey if you want automation: reminders and task automation need Business at $89 a user
• Watch out: monthly billing is open only to teams of 4 or more users

Pick TaxCycle if

• Fits if your firm prepares Canadian T1 and T2 returns on Windows machines
• Makes sense if you are moving a practice over from ProFile, Cantax, Taxprep or DT Max

Look elsewhere if

• Skip it if you use a Mac or work in a browser, as it is Windows only
• Pricey if you need several modules, since each is licensed per user per tax year and extra users cost $238 to $944 each
• Watch out: the Suite prices on the page are sale prices until about December 17, and the page does not name the currency
• Watch out: refunds apply to first purchases of the current-year product and may be prorated or declined after February 28

Karbon

Shared email triage

Team members can share, assign and comment on client emails, with comments and @mentions on emails, tasks and notes.

Workflow templates

Work is created from templates with statuses and types. Limits rise by plan: 35, 50 or unlimited statuses and 40, 75 or unlimited templates.

Client requests and portal

Clients get requests, file uploads and comments through a portal. Automatic client reminders need the Business plan.

Carry forward from other software

The trial page says returns from Intuit ProFile, Cantax, Taxprep and DT Max can be carried forward into TaxCycle.

TaxFolder client portal

TaxFolder adds e-signatures and a client portal. It is licensed until the end of 2027 and sold on its own or bundled with the suite.

DoxCycle document management

DoxCycle handles scanned and captured client documents and extracts data from them. It needs a TWAIN or WIA scanner for scanning.

Client Manager and Template Editor

Included in the Complete Tax Suite and Tax Basics bundles: a client list for the practice and an editor for letter and engagement templates.
