Taxdoo is an automated financial compliance platform developing a sales-tax automation software to manage sales tax in online retail.

Taxdoo builds API-based tools to help e-commerce companies with tax compliance and other accounting needs.

Taxdoo was co-founded in 2016 by Matthias Allmendinger, Roger Gothmann and Christian Königsheim. The company is headquartered in Hamburg, Germany.


Taxdoo uses automation to meet the tax and compliance burden faced by cross-border e-commerce companies that sell on various marketplaces and platforms such as Amazon, eBay and Shopify.


Taxdoo allows companies to automatically query and pull out transaction data needed to calculate VAT. Its APIs now include, in addition to a wider set of VAT calculators, tools to manage accounting and invoicing.


Taxdoo currently works with over 1,700 marketplaces, online merchants, and enterprises, integrating with the platforms that they use in turn to sell online. Markeplaces include Amazon, eBay, Xentral, Shopify, and Afterbuy.


Taxdoo is backed by Tiger Global, Accel, Visionaries Club, 20VC, HTGF, and others. The company raised $64M in Series B round on Dec 16, 2021. This brings Taxdoo's total funding to $85.7M to date. The latest round valued the company at just over $350M post-money.
