Frequently asked questions

How do I export data from QuickBooks?

In QuickBooks, navigate to Reports or Settings and look for "Export" options. We support both CSV transaction exports and full Excel data exports where available.

Is my financial data secure?

Yes. Taxilax runs entirely on your local machine via MCP. Your QuickBooks exports are processed locally and never sent to external servers.

What UK tax calculations are supported?

We support corporation tax estimates, dividend tax calculations, personal allowance tracking, and expense categorization aligned with HMRC requirements.

Can I use this for Self Assessment?

Yes! Ask Claude Code to summarize your income, expenses, and dividends in the format needed for your Self Assessment tax return.

Does it work offline?

The MCP server runs locally, but Claude Code typically requires an internet connection for AI processing.
