Sales tax automation for US e-commerce; acquired by Stripe (2021) and integrated into Stripe Tax; previously served tens of thousands of merchants across all 50 states post-Wayfair ruling.
TaxJar is a Portland, Oregon-based sales tax automation platform that was acquired by Stripe in 2021 and subsequently integrated into Stripe Tax, Stripe's native sales tax and VAT calculation product. Founded in 2013, TaxJar built one of the most widely adopted sales tax compliance platforms for e-commerce businesses in the United States, automating the calculation, collection, reporting, and filing of sales tax across all 50 states. Before the Stripe acquisition, TaxJar served tens of thousands of online merchants, marketplaces, and SaaS companies that faced the complex and rapidly evolving U.S. sales tax landscape following the 2018 South Dakota v. Wayfair Supreme Court ruling, which enabled states to impose sales tax collection requirements on out-of-state sellers.\n\nTaxJar's pre-acquisition product addressed the fragmented state-by-state sales tax compliance problem comprehensively: it connected to e-commerce platforms including Shopify, WooCommerce, Magento, and Amazon, automatically calculating the correct sales tax rate for every transaction based on origin and destination addresses and product taxability rules. The platform aggregated sales data into state-by-state reports and automatically filed returns directly with state tax authorities, eliminating the manual monthly filing burden that required hours of staff time for merchants with sales in many states. Economic nexus threshold monitoring—tracking whether a merchant had crossed each state's revenue threshold triggering collection obligations—was a key capability given the rapidly changing post-Wayfair compliance landscape.\n\nFollowing the Stripe acquisition, TaxJar's technology forms the foundation of Stripe Tax, which provides real-time tax calculation embedded directly in Stripe's payment processing API. This integration means that any business accepting payments through Stripe can enable automatic sales tax, VAT, and GST calculation and collection without a separate tax software implementation. TaxJar continues as a brand for its AutoFile and reporting services for merchants on platforms outside the core Stripe ecosystem.
Global payments infrastructure founded by Patrick and John Collison (YC W10); $1.4T payments volume in 2024; $18B+ revenue; $106.7B valuation as of Sept 2025; powers everything from startups to Fortune 500 companies with developer-first API design.
Stripe is a global payments infrastructure company founded in 2010 by Irish brothers Patrick and John Collison, headquartered in San Francisco, California and Dublin, Ireland. Stripe was born from the insight that accepting payments online was unnecessarily complex for developers, and that a well-designed API could unlock an entire generation of internet businesses. The company went through Y Combinator's Winter 2010 batch and grew to become the defining payments infrastructure layer of the modern internet economy, processing payments for businesses in virtually every industry worldwide.\n\nStripe's platform provides payment processing, fraud prevention via Stripe Radar, subscription billing, revenue recognition, banking-as-a-service through Stripe Treasury, corporate card issuance, identity verification, and tax compliance tools. It serves a spectrum from early-stage startups to publicly traded enterprises including Amazon, Google, Salesforce, and Shopify. Stripe's developer-first philosophy — comprehensive documentation, SDKs in every major language, and a sandbox testing environment — created an ecosystem of millions of businesses built entirely on its infrastructure.\n\nStripe processed $1.4 trillion in total payment volume in 2024 and generates over $18 billion in annual revenue, with a valuation of $106.7 billion as of September 2025. The company has remained private longer than most comparably sized technology companies, giving it flexibility to invest in long-term product expansion. An April 2024 partnership with Apple Pay extended Stripe's reach further into mobile and in-store commerce. Stripe competes with Adyen, Braintree (PayPal), and Square, but its developer ecosystem depth and global infrastructure make it the default payments platform for a generation of technology companies.
