Both are strong products used by thousands of firms. They just solve different problems. Here is a plain-English side-by-side, with current pricing, and a third option worth knowing about if you run a small firm in the US or Canada.
The short answer
Pick TaxDome if the client-facing side is your bottleneck: portal, document collection, e-signatures, proposals, and payments in one suite. It costs about $83 to $100 per user per month and most seats need an annual term.
Pick Karbon if the inside of your firm is the bottleneck: shared email triage, team workflow, and task automation are its core strengths. It runs $59 to $99 per user per month, and automatic client reminders need the Business plan.
Look at MyCPACRM if you are a small US or Canadian firm and per-user pricing bothers you: one flat price per firm from $59/month, add-ons priced per firm instead of per user, and IRS + CRA filing deadlines calculated automatically.

Every major IRS and CRA filing type is built in, and deadlines are calculated from each client's year-end. Cross-border firms run both countries in one system.
The core platform covers clients, IRS and CRA filing tracking, automatic email and SMS reminders, documents, and the workflow board. Optional add-ons like the client portal bundle and e-signatures are $29 to $39 per month for the whole firm, never per user.
Solo $59, Team $99 (3 users), Team Plus $149 (5 users), in USD or CAD. Monthly billing is available too. See full pricing.
Karbon starts lower: Team is $59 per user per month billed annually. TaxDome Pro works out to about $83 per user per month on an annual term, or $100 monthly. For a 3-person firm that is roughly $177/month on Karbon Team versus about $250/month on TaxDome Pro. Both grow with every hire because both charge per user.
TaxDome is strongest on the client-facing side: portal, document collection, e-signatures, proposals, and payments. Karbon is strongest on the inside of the firm: shared email triage, workflow, and task automation. Decide which side of your practice hurts more today.
TaxDome standard seats run on 1 to 3 year terms, with monthly seats only on the Pro plan at a premium. Karbon offers monthly billing at a higher per-user rate. If you want to avoid a commitment, check the monthly math carefully on both.
Three reasons firms tell us: flat per-firm pricing instead of per-user seats, native support for both IRS and CRA filings with deadlines calculated automatically, and add-ons that cost one flat amount for the whole firm instead of multiplying by headcount. If that sounds like your firm, watch the demo.
