The 2018 Federal Allowance Calculator helps you determine your federal tax allowance based on the official 2018 tax brackets and rates. This calculator provides a quick and accurate way to understand how much of your income is taxed and how much is left as take-home pay.
What is Federal Allowance?
The federal allowance refers to the portion of your income that is exempt from federal income tax. In the United States, the federal government sets standard deduction amounts that reduce your taxable income. These allowances are adjusted annually based on inflation and other economic factors.
Federal allowance amounts are different from state allowances. While federal allowances are set by the IRS, state allowances vary by state and are typically lower than federal amounts.
Understanding your federal allowance is crucial for effective tax planning. It helps you determine how much of your income will be subject to federal income tax and how much will be left as take-home pay.
2018 Federal Allowance Rates
In 2018, the federal government established specific standard deduction amounts for different filing statuses. These amounts were adjusted for inflation from previous years. Here are the 2018 federal allowance amounts:
- Single filers: $12,000
- Married filing jointly: $24,000
- Married filing separately: $12,000
- Head of household: $18,000
The federal allowance amounts are based on the following formula:
Federal Allowance = Base Amount + Inflation Adjustment
The base amounts were last set in 2017, and the inflation adjustment was applied to bring them up to date for 2018.
These amounts are crucial for determining your taxable income. Any income above these amounts will be subject to federal income tax.
How to Calculate Federal Allowance
Calculating your federal allowance involves several steps. Here's a step-by-step guide:
- Determine your filing status (single, married filing jointly, married filing separately, or head of household).
- Identify the base federal allowance amount for your filing status from the 2018 table.
- Calculate your taxable income by subtracting your federal allowance from your total income.
- Apply the appropriate federal income tax rate to your taxable income.
- Subtract the resulting tax from your total income to determine your take-home pay.
The formula for calculating federal allowance is:
Federal Allowance = Base Amount - (Total Income - Federal Allowance)
This formula helps you determine how much of your income is exempt from federal income tax.
Using the calculator on this page, you can quickly and accurately determine your federal allowance based on your income and filing status.
Federal Allowance vs State Allowance
While federal allowance amounts are set by the IRS, state allowances vary by state and are typically lower than federal amounts. Here's a comparison of federal and state allowances:
| Filing Status | Federal Allowance (2018) | State Allowance (Example: California) |
|---|---|---|
| Single | $12,000 | $4,300 |
| Married Filing Jointly | $24,000 | $8,600 |
| Married Filing Separately | $12,000 | $4,300 |
| Head of Household | $18,000 | $8,600 |
As you can see, federal allowances are significantly higher than state allowances. This means that more of your income is exempt from federal income tax compared to state income tax.
State allowances can vary widely by state. The example above shows California's state allowances, but other states may have different amounts.
