Multi-state tax problems are usually one of three patterns: someone moved mid-year and owes part-year returns in two states, someone works remotely for a company in a different state, or a business has employees or customers in several states. The right CPA matches the pattern. For movers, the right filings preserve residency credits and avoid double taxation. For remote workers, convenience-of-employer rules in New York, Pennsylvania, and a few other states can override your physical location. For businesses, nexus thresholds vary by state and by tax type (income, sales, franchise), and registering proactively is usually cheaper than waiting for a notice.
