LLC vs S Corp Tax Calculator - SE Tax Savings
LLC vs S Corp Tax Calculator - SE Tax Savings
Compare LLC taxed as sole proprietor versus S Corp election for USA. Estimate SE tax savings, reasonable salary impact, and net benefit after payroll and CPA costs.
Why LLC vs S Corp Choice Feels Different In Texas California And Florida Homes
A consultant in Austin Texas ZIP 78701 with net business income 100000 dollars and reasonable salary 60000 dollars sees a different total cost picture than same consultant in San Francisco California ZIP 94102 and Miami Florida ZIP 33101. Federal SE tax math is identical in all three states. LLC taxed as sole proprietor pays SE tax on full net income adjusted by 0.9235 factor. S Corp pays SE tax only on W2 salary. Distribution portion avoids SE tax. That creates gross savings of about 5646 dollars on 100000 income with 60000 salary example.
What changes is state level friction. Texas LLC annual cost is low, no state income tax, S Corp extra costs mainly CPA for Form 1120S and payroll service around 800 to 1500 dollars per cycle. California adds 800 dollars minimum franchise tax for LLC and S Corp, plus S Corp 1.5 percent tax on net income with 800 minimum. For 100000 income, California S Corp tax adds about 1500 dollars, which reduces net benefit. Florida has no individual income tax, LLC annual report about 138 dollars, S Corp similar, so net savings remain close to Texas level. New York adds publication costs and higher CPA fees, Illinois has flat income tax plus replacement tax for S Corp, Ohio has commercial activity tax thresholds.
Take same 100000 income 60000 salary example. Texas net after 1200 extra costs equals about 4446 dollars annual benefit. Florida similar about 4446 dollars. California with 800 minimum plus 1500 S Corp tax plus 1200 extra costs total about 3500 extra, net drops to about 2146 dollars. If income rises to 150000 with salary 80000, gross savings about 8470 dollars, Texas net about 7270 dollars, California net about 4970 dollars after state S Corp tax. If income is only 50000 with salary 40000, gross savings about 1411 dollars, net after 1200 costs only about 211 dollars, often not worth complexity.
Reasonable salary drives outcome more than state. Austin consultant who tries 20000 salary on 100000 income to inflate savings risks IRS reasonable compensation challenge. Market rate for same role in Austin might be 55000 to 70000 dollars. Los Angeles market rate higher due to cost of living, often 65000 to 85000 for same duties. Using defensible salary makes comparison honest and keeps estimate useful for planning discussion with CPA.
What Drives Your LLC vs S Corp Savings Inside Real Formula
First driver is net business income. This is profit after ordinary business expenses, before self employment tax and income tax. Higher profit creates larger base for SE tax under LLC and larger potential savings if portion can shift to distribution.
Second driver is reasonable salary. IRS requires S Corp shareholder who works in business to take reasonable W2 salary before distributions. Salary is subject to FICA. Distribution is not subject to SE tax. Lower salary within reasonable range increases SE tax savings, but must be defensible based on duties, hours, qualifications, location and industry data.
Third driver is SE tax rate and wage base. SE tax is 15.3 percent on first portion up to Social Security wage base set by SSA, then 2.9 percent Medicare on remainder plus 0.9 percent additional Medicare tax above threshold for single or joint filers. Factor 0.9235 adjusts net earnings. Latest wage base is around 176100 dollars. This calculator applies wage base limit to avoid overstating SE tax at high incomes.
Fourth driver is S Corp additional costs. Payroll service about 300 to 600 dollars per cycle, CPA for 1120S about 500 to 1200 dollars, state fees vary. These are deductible for income tax but still reduce SE tax net benefit. Enter actual quotes for your state to see true net.
Fifth driver is QBI deduction interaction. Both LLC and S Corp may qualify for up to 20 percent qualified business income deduction under Section 199A subject to thresholds and W2 wage limits. Salary level can affect QBI wage limit calculation. This calculator focuses on SE tax only and notes QBI as separate consideration to discuss with CPA.
How To Use Calculator Without Mistake
First, enter net business income. Use profit after expenses from your books for latest cycle. If income varies, use average expected for coming cycle or run low and high scenarios.
Second, enter reasonable salary if S Corp. Research market salary for your role in your ZIP. For Texas service business, check Bureau of Labor Statistics and local job postings. For California, include higher cost of living adjustment. Use 60 percent of net as starting point only if it matches market data.
Third, enter annual S Corp extra costs. Include payroll software, CPA for 1120S, state S Corp filing or franchise tax if applicable. Texas example 1200 dollars, California example 2300 to 3500 dollars including franchise and 1.5 percent tax, Florida example 1000 dollars.
Fourth, select state where you file. State does not change federal SE math but helps you remember local fee impact and prompts you to enter correct extra costs.
Fifth, review monthly and annual net. Calculator shows LLC SE tax, S Corp SE tax, distribution amount, gross savings, net savings after costs, and ten cycle projection. Use net savings to decide if complexity is worth it.

Distribution No SE Tax: Portion of income not subject to SE tax under S Corp. Income minus salary. Example 100000 minus 60000 equals 40000 dollars distribution.
10 Year Gross Savings: Gross savings times ten cycles before extra costs. Shows long term SE tax avoided. Example 5652 times ten equals 56520 dollars. Net ten year equals gross ten year minus costs times ten.

Austin Texas 78701 Income 100000 Salary 60000 Costs 1200: LLC SE about 14130, S Corp SE about 8478, Distribution 40000, Gross savings about 5652, Net about 4452 per cycle, Ten year gross about 56520.

Mistakes That Break LLC vs S Corp Math
- Setting salary too low to inflate savings: IRS requires reasonable compensation. Too low salary risks reclassification, penalties and interest. Use market data for your role and ZIP.
- Ignoring wage base limit: Above wage base about 176100 dollars, Social Security portion stops, SE rate drops to 2.9 percent. Ignoring overstates savings at high incomes.
- Forgetting extra costs: Payroll, CPA 1120S, state fees reduce net benefit. Include all recurring costs to see true net.
- Thinking S Corp saves income tax: S Corp saves SE tax, not federal income tax on same net. Income tax applies to both salary and distribution in S Corp, and to full net in LLC.
- Ignoring QBI and state S Corp tax: California charges 1.5 percent on S Corp net, minimum 800 dollars. QBI deduction limits may change with W2 wages. Include these in full planning.
How To Budget After Estimate
Use net annual savings to compare with formation and compliance effort. If net is 4000 dollars per cycle in Texas after 1200 costs, that equals about 333 dollars per month extra cash flow before income tax. Set aside salary payroll taxes monthly, pay quarterly estimated income tax on both salary and distribution, keep separate bookkeeping for reasonable salary documentation. If net is under 1000 dollars, consider staying LLC for simplicity and revisit when income grows. For California residents, add 800 minimum plus 1.5 percent to extra costs field to see realistic net. For New York, include publication and higher CPA fees.
Important Limitations To Remember
