TaxCalc vs TaxDome (2026): which should you pick?

TaxCalc

• UK accountancy practices filing returns for clients
• Small practices starting at 12 clients

TaxDome

• Tax and accounting firms that want one system for clients and work
• Firms that exchange documents and signatures with clients online
• Firms that bill clients in QuickBooks Online

TaxCalc

• Prices are in pounds, UK only, banded by client numbers; practices above 1,000 clients are sold through sales.
• The pricing page does not say whether prices include VAT; the product page says 'per year'.
• Mixed tax return bundles are sold through sales; accounts production, VAT and MTD filers are separate products.
• CloudConnect cloud hosting is a paid add-on; Windows, Mac and Linux support comes from the page's structured data, not a visible requirements page.

TaxDome

• Pricing could not be read: the vendor's site answered with a bot check, so no plans or prices are listed here.
• Clients need their accountant to sign up for TaxDome before they can use the client portal app.
• The mobile apps listed here are for iPhone and iPad; no Android listing was read.
