State tax planning is one of the most overlooked areas of business tax strategy, yet the difference in state tax costs can exceed the difference in federal tax treatment between entity types. A business with $500,000 in net income will pay $0 in state income tax in Wyoming but approximately $66,500 in California (13.3% top rate). That spread is larger than the difference between S-Corp and C-Corp federal treatment for many businesses. The common misconception is that incorporating in a low-tax state eliminates state tax exposure, but this isn’t how state taxation works: a business pays state income tax in every state where it has nexus (a sufficient connection to the state), regardless of where it is incorporated. After the Supreme Court’s decision in South Dakota v. Wayfair (2018), economic nexus (based on sales into a state) can trigger state income tax obligations even without any physical presence. For multi-state businesses, the key planning tool is the apportionment formula, which determines how much of the business’s total income is taxable in each state. Most states now use a single-sales-factor formula (only sales are weighted), which means a business with operations in a high-tax state but sales primarily in low-tax states can significantly reduce its overall state tax burden.

✓Key takeaway

State income tax rates (2025, selected states):

State	Top Corporate Rate	Top Individual/Pass-Through Rate	Other Taxes
California	8.84%	13.3%	$800 minimum franchise tax
New York	7.25% (6.5% general + 0.75% MTA surcharge for NYC area)	10.9% (+ 3.876% NYC)	Fixed dollar minimum
Texas	No income tax	No income tax	Franchise (margin) tax: 0.375-0.75% of revenue
Florida	5.5%	No income tax
Wyoming	No income tax	No income tax	No franchise tax
Nevada	No income tax	No income tax	Commerce tax (0.051% on gross revenue over $4M)
Delaware	8.7%	6.6%	Franchise fee ($400-$200,000+ based on authorized shares)
South Dakota	No income tax	No income tax	No franchise tax
Washington	No income tax	No income tax (7% on capital gains over $262,000)	B&O tax (0.138-3.3% of gross revenue)
New Jersey	11.5% (over $10M) / 9% (over $1M) / 6.5% (under $1M)	10.75%

Common misconceptions about state of incorporation:

Misconception	Reality
”Incorporate in Delaware to avoid state tax”	Delaware has an 8.7% corporate tax rate; you still owe tax in states where you have nexus
”Incorporate in Wyoming/Nevada for no state tax”	You still owe tax in your home state and any state where you have nexus
”Work from home in a no-tax state to avoid state tax”	If your business has employees, property, or sales in other states, you have nexus there
”Only physical presence creates nexus”	After Wayfair, economic nexus (sales thresholds) creates nexus in most states

How do you structure to minimize state taxes?

Hypothetical example

Round numbers. For current guidance, see IRS state government websites. A business owner lives in California and is considering where to incorporate an online service business that sells to customers nationwide. The business has $1,000,000 in net income and no employees or offices outside California.

Option 1: California LLC (domestic filing)

Tax	Amount
California income tax (13.3% on pass-through income)	$133,000
California LLC fee (based on gross receipts)	$6,000 (assuming $1M-$5M gross receipts)
Total California tax	$139,000

Option 2: Delaware LLC (foreign-qualified in California)

Tax	Amount
Delaware: No income tax on LLCs with no Delaware operations	$0 (annual $300 franchise tax only)
California: Still owes full California income tax (has nexus through the owner’s California residence)	$133,000
California LLC fee	$6,000
Delaware annual report / franchise tax	$300
Registered agent fee (Delaware)	$200
Total tax	$139,500

Result: incorporating in Delaware does NOT save any California tax. The owner has nexus in California through their residence and operations, so California taxes 100% of the income regardless of where the LLC is formed. Delaware adds $500 in annual fees with no tax benefit.

When incorporating outside your home state DOES help:

Multi-state scenario: Same business, but the owner moves from California to Florida (no income tax) and has no remaining California nexus (no employees, property, or sales into California).

Tax	California LLC	Florida LLC
State income tax	$133,000 (CA)	$0 (FL has no individual income tax)
Entity fees	$6,000 (CA LLC fee)	$150 (FL annual report)
Total	$139,000	$150

Savings from the move: $138,850/year. The incorporation state matters less than WHERE the owner lives and WHERE the business operates.

Multi-state apportionment example: A business with $2,000,000 in net income has operations in 3 states:

State	Sales in State	% of Total Sales	Apportioned Income	Tax Rate	Tax
California (single-sales factor)	$3,000,000	30%	$600,000	13.3%	$79,800
Texas (no income tax)	$4,000,000	40%	$800,000	0%	$0
New York (single-sales factor, with adjustments)	$3,000,000	30%	$600,000	6.5%	$39,000
Total	$10,000,000	100%	$2,000,000		$118,800

Effective combined state rate: $118,800 / $2,000,000 = 5.94%

If the business could shift sales from California to Texas (through a Texas-based fulfillment center or marketplace), the apportionment would change:

State	Sales in State	% of Total Sales	Apportioned Income	Tax Rate	Tax
California	$2,000,000	20%	$400,000	13.3%	$53,200
Texas	$5,000,000	50%	$1,000,000	0%	$0
New York	$3,000,000	30%	$600,000	6.5%	$39,000
Total	$10,000,000	100%	$2,000,000		$92,200

Savings from sales shift: $26,600/year.

State entity choice considerations:

Factor	Best Entity Choice
California resident, single-state business	S-Corp (avoids $800 LLC min + LLC fee; QBI deduction available)
Multi-state service business	S-Corp or multi-member LLC (simplifies withholding and composite returns)
Venture-backed startup expecting acquisition	Delaware C-Corp (Court of Chancery, predictable corporate law, investor expectations)
Asset protection priority	Wyoming LLC (strong charging order protection)
Privacy priority	Wyoming or Nevada LLC (no public disclosure of members)
Real estate holding	LLC in the state where the property is located (simplest nexus)

State-specific traps:

State	Trap
California	$800 minimum franchise tax applies to LLCs and corporations even if no income; first-year exemption available for new LLCs
California	LLC fee based on gross receipts (not income); a money-losing business with high revenue still pays $6,000+
New York	Publication requirement for LLCs (ads in two newspapers for 6 weeks, costs $1,000-$2,000 in NYC counties)
Delaware	Franchise tax can be high based on authorized shares (use the assumed par value method to minimize)
Texas	Franchise (margin) tax is based on revenue, not profit; businesses with thin margins pay tax even when losing money
Washington	B&O tax is based on gross receipts; no deduction for COGS or expenses
Ohio	Commercial Activity Tax (0.26% on gross receipts over $1M) on top of individual income tax on pass-through income
