What a team of each size pays in a year
Annual list-price totals: Karbon billed annually, and TaxDome on a one-year commitment. TaxDome Essentials is a single-seat plan, so it appears only for one user. Karbon’s monthly billing, which is more expensive per user, is offered only to teams of four or more.
| Plan | 1 user | 2 users | 5 users | 10 users | 20 users |
|---|---|---|---|---|---|
| Karbon Team | $708 | $1,416 | $3,540 | $7,080 | $14,160 |

Billing and commitment
- Karbon shows two prices per plan: a lower per-user price when paid annually and a higher one when paid monthly. Monthly billing is offered only to teams of four or more; annual billing has no minimum team size.
- TaxDome shows three per-seat prices at once, for a one-, two- or three-year commitment. The lowest figures need the longest commitment. The one-year price is the like-for-like figure against a month-to-month tool.
Price history
The one dated increase we have documented across the two: TaxDome Pro $600 to $800 on February 13, 2023.
TaxDome restructured its plans in 2025 (see the plan and policy changes in the price history), so compare Pro before and after 2025 with care: the plan kept its name while firms were moved between plans. Full detail is on the Karbon price history and TaxDome price history pages. Karbon’s page has been read on 45 days since September 12, 2026, and its listed prices have not changed in that time.
What to check on each vendor’s page
TaxDome
- The price depends on the commitment length. All three prices appear on the page at once; the lowest figures need a three-year commitment. When comparing with month-to-month tools, use the one-year price.
- The savings calculator quotes other vendors, not TaxDome. The pricing page embeds a savings calculator that lists competitors’ prices as plain text. Those figures are not TaxDome prices, so check the heading around any number.
- Large teams and seasonal staff are priced separately. Teams of 25 or more seats need a custom quote. A TaxDome help-center article lists short-term seasonal seats separately, for example $500 per seat per four-month term on Business.
- Other regions may differ. TaxDome publishes pricing pages for other locales that can carry different prices. Use taxdome.com/pricing for US dollar prices.
Karbon
- Monthly billing needs four or more users. The line on the plan cards is a condition on paying monthly, not a minimum number of users needed to buy the plan.
- Calculator figures are examples. The page’s return-on-investment calculator prints dollar figures that are worked examples, not prices.
- eSignature bundles and payment-processing fees are extras. They are priced separately from the plans.
