Schedule nowWhy do online businesses need an accountant for sales tax?
Since the 2018 Wayfair decision, you can owe sales tax in a state just by crossing a sales threshold there — typically $100,000 or 200 transactions a year — even with no physical presence. Tracking 50 states' rules and deadlines by hand is exactly where e-commerce and SaaS businesses get into trouble. A small business accountant runs a nexus study, registers you where you owe, files monthly or quarterly returns, and handles voluntary disclosure if you're behind — often waiving penalties. Dushyant Hirwani Accounting manages multi-state sales tax for Shopify, Amazon, and SaaS sellers across all 50 states, remotely, with clear per-state filing pricing.
Sales Tax Compliance is one part of full-service small business accounting. Most clients pair it with monthly bookkeeping and year-round tax planning so their books, payroll, and taxes all stay in sync with one accountant.
