How to Switch from TaxDome (2026 Migration Guide)

If you're an accounting firm using TaxDome and considering switching, this guide covers everything — what to export, how to migrate clients, and how to avoid the common mistakes that turn a 1-week migration into a 3-month nightmare.

Why firms typically leave TaxDome

TaxDome is a powerful platform with deep features, but it's built primarily for mid-sized US accounting firms. The most common reasons smaller firms switch away:

Cost scales aggressively with team size. Per-user pricing of ~€55/month means a 5-person firm pays €3,300/year. As you grow, the bill grows linearly.

Complexity overwhelms small firms. TaxDome was designed for firms with dedicated admin staff who can configure workflows, manage permissions, and maintain integrations. Solo and small firms often use 20-30% of the available features — while paying for 100%.

US-centric design. Tax organizers, IRS transcript integration, and US-format documents are excellent for American firms, but irrelevant for UK and EU practices that need GDPR-native infrastructure and EU-format invoices.

Steep onboarding curve. Most firms report 4-8 weeks of setup before they're fully running on TaxDome. That's expensive in lost time.

If these resonate, see our FirmFlow vs TaxDome comparison for a side-by-side breakdown.

What you can export from TaxDome

Before you switch, understand what data is portable and what isn't:

Easily exportable: Client list (CSV), contact details, invoices (PDF and CSV), time entries (CSV), documents (bulk download as ZIP).

Exportable with effort: Custom workflow templates (need to be recreated manually in the new platform), engagement letter templates (export as PDF, recreate as templates).

Not directly exportable: Email history (re-link to your email provider), task automation rules (must be recreated), client communication threads (download as PDF for archive).

The good news: for most small firms, the "not exportable" data isn't critical for daily operations. Email history lives in your email client. Task rules can be recreated in 30 minutes.

The 4-week migration plan

Don't try to migrate overnight. The lowest-risk path is a phased switch:

Week 1: Setup and validation. Sign up for the new platform's free trial. Add your branding (logo, colors, firm details). Export your TaxDome client list to CSV. Import to the new platform. Test the full workflow with 2-3 internal "dummy" clients — send an engagement letter, get it signed, send an invoice, get it paid.

Week 2: New clients only. Send all NEW client engagements through the new platform. Continue running existing clients on TaxDome. This proves the new workflow without disrupting in-progress work.

Week 3: Migrate active clients. Move active clients in batches of 10. Start with longest-tenured clients — they'll tolerate the change best. Send a friendly "we've upgraded our tools" email with the new portal link. Most clients adapt within one email.

Week 4: Cancel TaxDome. Once all active clients are migrated and you've confirmed nothing is broken, cancel your TaxDome subscription. Keep the account in read-only mode for 30 days as backup, then close it permanently.

Common migration mistakes to avoid

Mistake 1: Migrating everything at once. Trying to move 200 clients in one day creates client confusion, missed signatures, and stressful weekends. Phased migration over 4 weeks is always smoother.

Mistake 2: Not telling clients what's happening. Clients receiving emails from a new platform without context will assume phishing. Send a brief notice 1 week before they're migrated, then a friendly intro email when their account is ready.

Mistake 3: Cancelling TaxDome too early. Wait until you've completed at least one full billing cycle on the new platform before cancelling. There's usually a small workflow you forgot to migrate.

Mistake 4: Not exporting historical data. Even after switching, you'll occasionally need to reference old documents. Download a complete archive of TaxDome data before closing the account — you can't get it back later.

Where to switch to

The best alternative depends on your firm size and needs:

For solo and small firms (1-5 people): FirmFlow at €29-89/month flat. Built for firms that need everything TaxDome does but without per-user pricing or complexity. See the full comparison.

For mid-size firms (10+ people): Karbon if you need workflow automation, or staying on TaxDome may actually be the right call — the per-user economics work better at scale.

For law firms: Clio if you need trust accounting and LEDES billing. See FirmFlow vs Clio.
