Frequently Asked Questions
Which invoice platforms do you support?
TaxWithhold integrates with QuickBooks, FreshBooks, and Wave. We sync your invoices automatically and recalculate your quarterly estimates whenever new income is recorded.
How accurate are the tax estimates?
We use official IRS safe harbor formulas (90% of current year or 100% of prior year tax). Estimates are updated in real time as invoices come in, minimizing underpayment penalties.
Is my financial data secure?
Yes. All data is encrypted in transit and at rest. We use read-only OAuth connections to your invoice platforms and never store raw credentials.
