A married couple in Alabama with $120,000 of other income and a $250,000 long-term gain pays $35,835 of federal income tax, $4,560 of the 3.8% tax and $12,500 of Alabama tax, and keeps $197,105.

How the total tax breaks down

The key figures above show the final amount kept after all taxes. This result comes from three distinct layers. First, federal income tax applies to the gain. Second, a separate investment income tax adds to the bill. Third, Alabama imposes its own state tax. Each layer calculates independently based on the couple's filing status and income levels. The table below lists these amounts clearly. It separates the federal burden from the state obligation. The calculation assumes standard joint filing rules for this tax year. No special deductions or credits are included in this basic example. The figures reflect typical rates applied to the stated income levels. Use the calculator to test different scenarios.

Federal income tax calculation

Federal tax on long-term gains depends on the couple's other income. With substantial other income, the gain pushes into higher brackets. The table above shows the resulting federal income tax amount. This tax is not flat; it scales with total taxable income. The investment income tax adds a fixed percentage on top. This surtax applies when income exceeds certain thresholds. For a married couple filing jointly, these thresholds are higher than for singles. The combination of income tax and surtax forms the total federal liability. This amount reduces the net proceeds from the sale. The federal portion is usually the largest component of the total tax bill. It reflects the progressive nature of the federal tax system.

Alabama state tax treatment

Alabama treats capital gains as ordinary income. This means the state applies its standard bracket rates to the gain. There is no separate preferential rate for long-term holdings at the state level. The key figures above show the Alabama tax amount. This amount is calculated after federal taxes are determined. The state tax is deductible on the federal return in some cases, but this example shows the gross amounts. Alabama's tax is a flat percentage of taxable income within certain bands. For this example, the state tax is significant but smaller than the federal portion. The state does not offer additional breaks for long-term gains. The treatment is consistent regardless of how long the asset was held. See the Alabama page for specific bracket details.

Short-term versus long-term impact

Alabama taxes short-term gains identically to long-term gains. The state does not distinguish between holding periods. The key figures show the same state tax amount for both scenarios. This contrasts with federal rules, where holding periods affect rates. For the couple in this example, the state tax remains constant. The difference lies only in the federal calculation. Long-term gains often face lower federal rates if other income is low. However, with high other income, the difference may be minimal. The table above helps compare these outcomes. Readers should note that state rules are uniform across holding periods. This consistency simplifies planning for Alabama residents. The focus shifts to managing federal tax exposure through timing and income levels.
