How the 2018 Consultant Tax Calculator Works
The 2018 Consultant Salary Tax Calculator estimates your total tax liability for the 2018 tax year based on your gross income and state of residence. The calculation includes:
- Federal income tax
- State income tax (if applicable)
- Social Security tax (6.2%)
- Medicare tax (1.45%)
- Additional Medicare tax (0.9%) for high earners
This calculator uses the 2018 tax brackets and rates established by the IRS and individual state tax authorities. The results are estimates and should be used as a guide rather than definitive tax advice.
Tax Calculation Formula
The total tax is calculated as the sum of federal tax, state tax, and FICA taxes:
Total Tax = Federal Tax + State Tax + FICA Taxes
Where FICA taxes include Social Security (6.2%) and Medicare (1.45%) plus the additional Medicare tax (0.9%) for income over $200,000.
Federal Tax Rates for 2018
The federal tax rates for the 2018 tax year were as follows:
| Tax Bracket | Tax Rate |
|---|---|
| $0 - $9,525 | 10% |
| $9,526 - $38,700 | 12% |
| $38,701 - $82,500 | 22% |
| $82,501 - $157,500 | 24% |
| $157,501 - $200,000 | 32% |
| $200,001 - $500,000 | 35% |
| $500,001+ | 37% |
Standard deductions applied to these brackets. For example, single filers could deduct $6,350, while married filing jointly could deduct $12,700.
State Tax Rates for 2018
State income tax rates varied significantly in 2018. Some states had no income tax, while others had rates ranging from 1% to 13.3%. The calculator uses the standard rates for each state, which may differ slightly based on your specific situation.
For example:
- California: 1% to 13.3%

- Washington: No income tax
Note: Some states have exemptions or deductions that may reduce your taxable income. This calculator uses standard rates and does not account for all possible exemptions.
Example Calculation
Let's calculate the taxes for a consultant earning $120,000 in 2018 in California:
- Federal tax: $22,200 (using the 22% bracket for $120,000 - $38,700)
- California state tax: $4,800 (using the 13.3% rate)
- FICA taxes: $7,440 (6.2% Social Security + 1.45% Medicare)

This example shows how state tax rates can significantly impact your total tax liability.
