Verdict: Washington wins for most businesses
For most Washington-based businesses, forming locally in Washington is the smarter choice. You avoid paying fees in two states and managing compliance in both. South Carolina only makes sense if your business genuinely operates there, and even then the total costs deserve a hard look.

Compare LLC Costs: Washington vs South Carolina
Washington
South Carolina
Costs include every mandatory state charge: the filing fee, the report fee (annualised where a state files biennially), any state entity-level tax shown in its own row above, a one-time publication cost where a state requires publication, and any one-time registration charge a state requires before the LLC may trade. Annualising makes the 1, 3 and 5 year rows a cost of ownership rather than a payment schedule: a biennial state charges its whole report fee in the years it falls due and nothing in between. Entity-level taxes that only apply after a corporate election, or above an owner or income threshold, are excluded and flagged on the state's own cost page. New York's publication cost is carried at a $250 floor, roughly $200 of newspaper cost in a low-cost county plus the $50 Certificate of Publication fee. No county-clerk-designated New York City newspaper publishes a rate card, so the four-figure NYC estimates in wide circulation cannot be traced to a primary source and are not asserted here; budget for materially more than the floor if you file in a NYC county. Montana's annual report is free when filed by April 15 and $35 after, a waiver the Secretary of State applies at its discretion. Every fee was verified against the state's own fee schedule, statute, or revenue authority on 29 July 2026. Excludes registered agent and legal fees.

Filing Fees & Formation Costs
Washington charges $180 to form an LLC, while South Carolina charges $110. South Carolina is $70 cheaper upfront. The cost that usually gets overlooked: if you form in South Carolina but operate in Washington, you must also register as a foreign LLC in Washington (a $200 filing) and maintain a registered agent in South Carolina (typically around $150 per year). That puts the realistic first-year cost of the South Carolina route at roughly $460, versus $180 for simply forming in Washington. Only one side of this comparison is knowable: Washington publishes within 15 business days (paper), while South Carolina publishes no standard processing time, so the two can't be ranked against each other on speed.
Taxes: Washington vs South Carolina
Washington has no personal income tax, while South Carolina taxes individual income. Since pass-through LLC profits are taxed where you live and operate, a Washington-based owner keeps Washington's no-income-tax benefit either way. Forming in South Carolina adds no tax advantage. Washington imposes the Business & Occupation (B&O) tax on gross receipts.
Privacy & Asset Protection
Neither Washington nor South Carolina offers anonymous LLC formation: both states require owner or manager information on public filings. South Carolina requires managers to be listed on the Articles of Organization when the LLC is manager-managed, a public record. Business owners who prioritize privacy typically form a holding company in a state like Wyoming or New Mexico instead. Both states provide charging-order protection for LLC members, and for most small businesses the practical difference in asset protection between the two is minimal.
Annual Maintenance Costs
Washington LLCs file an annual report ($70, due in the anniversary month), and South Carolina LLCs file no annual report at all. If you form in South Carolina while operating in Washington, you maintain filings in both states, South Carolina's report plus Washington's equivalent for your foreign registration, and pay a South Carolina registered agent roughly $150 per year. That brings ongoing costs of the South Carolina route to roughly $220 per year, versus about $70 to keep a domestic Washington LLC in good standing. One more recurring cost to budget for: Washington imposes the Business & Occupation (B&O) tax on gross receipts.
When South Carolina Actually Makes Sense
Forming in South Carolina makes sense in a few specific situations: your business genuinely operates in South Carolina, with a real office, employees, or property there, or you're relocating to South Carolina in the near future and accept taking on South Carolina's personal income tax, which Washington doesn't levy. For a typical small business based in Washington, none of these usually apply. Registering a South Carolina LLC to do business back home means $200 in Washington foreign-registration fees, on top of South Carolina's $110 formation fee, while Washington's own annual report runs $70 a year and is due in the anniversary month. When in doubt, form where you actually do business.
