Sales tax nexus rules, economic and physical nexus thresholds, and multi-state compliance requirements
Hawaii has no sales tax — the GET taxes your gross receipts at 4.5% including county surcharges, and 4.712% is the most you may legally show a customer.
Three ways to move an LLC across state lines — domestication keeps your EIN, contracts, and tax elections when both states allow it; foreign qualification suits businesses staying active in both states; dissolve-and-reform means a new EIN and a new S election — plus a 7-item tax and paperwork checklist for the transition year.
Chicago's amusement tax runs on three tracks in 2026 — 9% on live admissions, 10.25% on streaming and paid TV, 3% on registered ticket resales — plus a new 10.25% sports wagering tax and a $0.50 per-user monthly social media levy above 100,000 Chicago consumers. Here are the rates, the limits of the 1,500-seat exemption, the $100,000 remote-seller safe harbor, and the filing deadlines that trigger assessments.
Seventeen states run back-to-school sales tax holidays in summer 2026, from Florida's 32-day window to Iowa's Friday-Saturday weekend, each with its own price caps — $75 clothing in Ohio, $300 in Connecticut, $40 on Maryland backpacks. Participation is mandatory for most registered retailers, and destination sourcing means online sellers with nexus must honor the holiday of the delivery state.
A throwback rule can push a home-state sales factor from 20% to 60% on the same revenue by adding untaxed 'nowhere' sales back to the numerator; throwout, which shrinks the denominator instead, takes it to 33%. About 20 states plus D.C. still throw back tangible sales, five repealed their rules since 2019, and P.L. 86-272 protects none of your SaaS receipts.
Gusto's acquisition of compliance-automation platform Mosey signals that multi-state registration is becoming a payroll-provider feature. Small businesses under 50 employees spend about $14,700 per employee per year on regulatory compliance, and a first hire in a new state triggers foreign qualification, withholding and SUTA accounts, workers' comp, and new-hire reporting — each with its own agency, deadline, and penalties.
Effective January 1, 2026, Illinois eliminated the 200-transaction economic nexus threshold, leaving a single $100,000 trailing-12-month revenue test for remote sellers. Here's who gains or loses nexus, how the August–October 2026 amnesty program works, and how to structure your books to answer state-by-state sales questions on demand.
Washington, D.C.'s general sales tax rate rises from 6% to 7% on October 1, 2026, and the District taxes digital goods and SaaS at the full rate with no B2B exemption. This guide covers the delayed Budget Support Act increase, D.C.'s $100,000/200-transaction economic nexus thresholds, and a five-step compliance checklist for invoices that straddle the rate change.
Envato's July 1, 2026 move to a flat 50% author revenue share replaces tiered rates that ran as high as 87.5%, and it exposes a deeper bookkeeping gap for WordPress plugin and theme businesses selling across Envato, Freemius, and direct Stripe checkout — gross revenue, marketplace fees, and license-renewal deferred revenue all need separate tracking, not one blended bank-deposit number.
Kentucky HB 757 eliminates the state's 200-transaction economic nexus threshold effective August 1, 2026, leaving a $100,000 revenue-only test — joining Alaska, Utah, and Illinois in a broader multi-state shift away from transaction-count triggers.
Maine now applies its 5.5% sales tax to streaming video, music, audiobook, and podcast subscriptions as of January 1, 2026, with economic nexus triggered at $100,000 in revenue from Maine customers.
Canada's GST/HST small-supplier exemption is based on worldwide taxable sales, not Canadian-only revenue, so a US seller with zero Canadian sales can already owe registration once global sales pass CA$30,000 in a quarter or over four trailing quarters.
