Formula Used

The calculation follows these steps:

1. Calculate taxable income after health insurance premiums:

Taxable Income = Total Income - Health Insurance Premiums

2. Determine tax liability based on tax brackets:

Tax Liability = Sum of (Taxable Income × Tax Rate for each bracket)

3. Calculate deductible health insurance premiums:

Deductible Premiums = Health Insurance Premiums × 0.75 (for self-employed) or 1.00 (for employees)

Note: The actual tax calculation is more complex and may vary based on your specific circumstances. This calculator provides an estimate based on standard tax brackets for 2018.

Worked Example

Let's calculate the tax liability for a single filer with $75,000 total income and $5,000 in health insurance premiums.

Taxable Income = $75,000 - $5,000 = $70,000
Tax Liability:
- $9,325 × 10% = $932.50
- ($37,950 - $9,325) × 15% = $4,343.75
- ($70,000 - $37,950) × 25% = $8,318.75
- Total = $932.50 + $4,343.75 + $8,318.75 = $13,595.00
Deductible Premiums = $5,000 × 0.75 = $3,750

The estimated tax liability is $13,595, with $3,750 in deductible health insurance premiums.

Interpreting Your Results

The calculator provides three key pieces of information:

Taxable Income: Your income after accounting for health insurance premiums
Tax Liability: The amount of tax you owe based on your taxable income
Deductible Premiums: The portion of your health insurance premiums that can be deducted from your taxable income

Use these results to complete your tax return accurately. Remember that this is an estimate and your actual tax liability may differ based on your specific circumstances.
