Taxwire is a tax compliance software company founded in 2023 and headquartered in New York. Its product, the Taxwire Compliance Platform, is an AI-native tax engine that calculates, registers and files sales tax and global VAT on behalf of finance and accounting teams, paired with a managed service team that handles judgment calls and reviews results. The platform covers the full compliance lifecycle, including nexus studies and nexus analysis, registration and filing automation, backfilings, tax calculation automation and multi-line invoice tax handling.
The engineering work spans thousands of tax jurisdictions across US states and international markets. Technical domains include the AI-native tax engine itself, sales tax compliance automation, global VAT compliance and the automation of calculations, registrations and filings. The company serves hundreds of customers, principally mid-market B2B software companies, e-commerce brands and accounting firms selling across state lines or internationally.
The company was founded by Andrew Rea, co-founder and CEO, who was previously head of finance at the fastest-growing school lunch company in America; Taxwire originated from his frustration with existing sales tax compliance tools. The stated approach combines an AI-native engine with a human managed service layer that stands behind every result. Taxwire has raised $27.7 million in total capital.
