Surcharge Taxable Income (STI) is a crucial concept in the United States tax system. It represents the portion of your taxable income that is subject to the additional Medicare tax, which is levied at a rate of 0.9%. STI is calculated by adding your regular taxable income to certain other amounts, such as net investment income and depreciation recapture. The purpose of STI is to ensure that high-income earners pay a proportionate share of Medicare expenses, which are primarily used to fund healthcare services for seniors and people with disabilities. By including additional income sources in the calculation of STI, the tax system aims to achieve greater fairness in the distribution of Medicare costs.
Taxable Income Calculation
Surcharge taxable income is a specific type of taxable income that is subject to an additional tax, known as a surcharge. It is calculated by making certain adjustments to the regular taxable income.
To calculate taxable income:
- Start with the gross income, which includes all taxable income sources, such as wages, salaries, business profits, and investments.
- Subtract eligible deductions and exemptions from the gross income, such as business expenses, charitable contributions, and the standard deduction.
- The result is the taxable income, which is then subject to the regular tax rates.
For surcharge taxable income, additional adjustments may be required, depending on specific tax laws and circumstances. These adjustments can include:
- Adding back certain previously deducted items, such as depreciation recapture
- Excluding specific income amounts, such as qualified dividends
- Making specific adjustments for certain types of businesses or investments
| Income Type | Surcharge Taxable Income Adjustment |
|---|---|
| Depreciation Recapture | Add back to taxable income |
| Qualified Dividends | Exclude from taxable income |
Once the surcharge taxable income has been calculated, it is subject to the applicable surcharge tax rate. The surcharge rate is typically a percentage that is added to the regular tax rate. The total tax liability is then the sum of the regular tax and the surcharge tax.
Surcharge Taxable Income
Surcharge taxable income (STI) is a modified taxable income used to calculate the amount of surtax owed by individuals and businesses.
Flat Surcharge
Individuals and business with STI over certain thresholds are subject to a flat surcharge of 3%. The thresholds are as follows:
- Single individuals: $250,000
- Married couples filing jointly: $500,000
- Married couples filing separately: $250,000
- Trusts and estates: $12,500
| Filing Status | STI Threshold | Surcharge Rate |
|---|---|---|
| Single | $250,000 | 3% |
| Married, filing jointly | $500,000 | 3% |
| Married, filing separately | $250,000 | 3% |
| Trusts and estates | $12,500 | 3% |
Surcharge Taxable Income
Surcharge taxable income is a special category of taxable income used to calculate the surcharge tax. Surcharge tax is an additional amount of income tax levied on high-income earners.
Progressive Surcharge
The surcharge is a progressive tax, meaning that the rate of taxation increases as the surcharge taxable income increases. Progressive taxation is designed to make the tax system more equitable by ensuring that high-income earners pay a higher proportion of their income in taxes.
Specific income levels (called “thresholds”) determine the progressive surcharge tax rates. Here’s how the rates are applied:
- Between $180,001 and $216,000: 15%
- Between $216,001 and $300,000: 25%
- Over $300,000: 30%
The surcharge is calculated as a percentage of the surcharge taxable income, which is calculated by subtracting a specific allowance from the individual’s taxable income.
| Filing Status | Allowance |
|---|---|
| Single | $56,800 |
| Married filing jointly | $113,600 |
| Married filing separately | $56,800 |
| Head of household | $85,000 |
Implications for Taxpayers
Understanding surcharge taxable income has significant implications for taxpayers, affecting their tax liabilities and financial planning.
- Higher Tax Rates: Taxpayers with surcharge taxable income are subject to higher federal income tax rates. The rates for 2023 range from 32% to 37%.
- Reduced Tax Savings: Deductions and credits that reduce taxable income become less effective for taxpayers with surcharge taxable income, as they do not apply to the amount subject to the surcharge.
- Increased Tax Burden: The additional tax liability imposed by the surcharge can increase the overall tax burden for taxpayers, potentially impacting their cash flow and investments.
Therefore, it is crucial for taxpayers to be aware of the surcharge and its potential implications to minimize their tax liability and plan their finances effectively.
| Filing Status | Threshold |

| Single | $57,876 |
| Married filing jointly | $115,752 |
