Understand your result
What the self-employment tax result means
Self-employment tax is only one part of the contractor tax picture. This page leads with that number and keeps the broader income-tax details optional.
Social Security + Medicare
The main result estimates the self-employment tax generated by modeled net earnings from the business.
Revenue minus business expenses
Self-employment tax is driven by net business profit rather than simply multiplying gross 1099 revenue by 15.3%.
Income tax is separate
Open the full breakdown to inspect federal income tax, state income tax and other modeled components.
How it works
Three steps, with the complexity kept underneath.
Enter income and state
Start with the simple annual business amount and state.
Add deductible costs
Optional business expenses reduce modeled net profit before the self-employment-tax calculation.
Review the broader picture
Use the detailed section when you also need income-tax and take-home context.
Why Analyze My Income
Built for the decision, not just the arithmetic.
Many quick calculators apply a generic percentage or stop at one federal tax estimate. Analyze My Income is designed to answer a practical compensation question while keeping the assumptions visible.
Scenario-specific, not a fixed markup
The engine uses the numbers you enter instead of assuming every contractor should simply add 20% or 30%.
2026 federal + state model
The standard model uses the documented 2026 federal path and a separate state-income-tax path for all 50 states.
Simple first, advanced when needed
The first screen asks for the minimum useful inputs. Expenses, insurance, withholding, benefits and other details stay optional.
Methodology you can inspect
Key formulas, assumptions, limitations and primary-source references are published rather than hidden behind the result.
Important limits
When the estimate may need more context
Entity elections such as S-corporation treatment, multiple businesses, unusual wage-base interactions and other special circumstances may require a different calculation path. Read the full model scope and methodology →

Frequently asked questions
Questions people ask before using the result
Is self-employment tax always 15.3% of my 1099 revenue?
No. The standard calculation applies the Schedule SE framework to net earnings from self-employment, not simply 15.3% of gross revenue.
Do business expenses reduce self-employment tax?
Eligible business expenses reduce modeled net business profit, which can reduce the net earnings subject to self-employment tax.
Does this include federal income tax?
The main answer focuses on self-employment tax. The broader breakdown also shows the supported federal and state income-tax estimates.
Calculation transparency
Tax year 2026 · Last reviewed August 18, 2026
Federal parameters are checked against IRS and Social Security Administration material; state parameters are checked against official state tax authorities. Current standard scope is primarily a single filer, resident ordinary income, one sole-proprietor 1099 business and the standard deduction. Local taxes and special situations can differ.
How this estimate works
The calculator starts with 1099 income, subtracts entered business costs, applies the documented 2026 federal self-employment and income-tax model for the selected filing status, then adds the selected state path when that filing-status/state combination is validated.
When this may not apply
Local taxes, credits, itemized deductions, plan-specific retirement contribution limits, multiple businesses, spouse-specific deductions, entity elections and special state rules can materially change the result. Non-single state-tax rules are not yet modeled for every state, and quarterly state rules are not modeled here.
