To address these challenges, companies are increasingly leveraging India as a centralized delivery location for managing multi-state tax compliance. India’s combination of skilled tax professionals, mature delivery models, advanced technology adoption, and cost efficiency has positioned it as a strategic partner in global tax operations.
Unlike federal taxation, state and local taxes in the U.S. are governed by more than 50 jurisdictions, each with distinct rules. Key complexities include:
State income and franchise taxes, each with unique tax bases, add-backs, and credits
Sales and use taxes administered at both state and local levels, with thousands of tax rates
Economic nexus standards following the South Dakota v. Wayfair decision
Apportionment methodologies, including single-sales factor, three-factor, and market-based sourcing rules
Local taxes, such as city, county, and special district levies
Managing multi-state tax compliance requires:
Collecting and validating large volumes of transactional data
Monitoring nexus thresholds across jurisdictions
Preparing and filing hundreds of tax returns annually
Responding to state notices, audits, and information requests
