**TAXTABLE_TAXYEAR_DEFINITION**
Wages, salaries, tips, etc.
This is your total taxable income for the year after deductions for retirement contributions such as 401(k)s, IRAs, etc. For tax filing purposes this would be the same as your Adjusted Gross Income (however the calculator is unable to take lower capital gains taxes into consideration).
Filing status
Choose your filing status. Your filing status determines the income levels for your Federal tax bracket. It is also important for calculating your standard deduction, personal exemptions, and deduction phase out incomes. The table below summarizes the five possible filing status choices. It is important to understand that your marital status as of the last day of the year determines your filing status.

Filing Status
Married Filing Jointly If you are married, you are able to file a joint return with your spouse. If your spouse died during the tax year, you are still able to file a joint return for that year. You may also choose to file separately under the status "Married Filing Separately".
Qualified Widow(er) Generally, you qualify for this status if your spouse died during the previous tax year (not the current tax year) and you and your spouse filed a joint tax return in the year immediately prior to their death. You are also required to have at least one dependent child or stepchild for whom you are the primary provider.
Single If you are divorced, legally separated or unmarried as of the last day of the year you should use this status.
Head of Household This is the status for unmarried individuals that pay for more than half of the cost to keep up a home. This home needs to be the main home for the income tax filer and at least one qualifying relative. You can also choose this status if you are married, but didn't live with your spouse at anytime during the last six months of the year. You also need to provide more than half of the cost to keep up your home and have at least one dependent child living with you.
Married Filing Separately If you are married, you have the choice to file separate returns. The filing status for this option is "Married Filing Separately".
Are you someone's dependent?
Choose 'no' if no one can claim you or your spouse as a dependent. Choose 'yes' if someone can claim you as a dependent. Choose 'both you and your spouse if you both are dependents. (You are a dependent if someone supports you and can claim a dependency exemption for you.)
Dependents qualifying for child tax credit
You may be entitled to a child tax credit for each qualifying child who was under age 17 at the end of the year if you claimed an exemption for that child. The credit is, however, phased out at higher incomes.
Standard deduction
Your standard deduction is used to reduce your taxable income if you do not use Schedule A to itemize your deductions, or if your Schedule A itemized deduction is less than your standard deduction. Your standard deduction is based on your filing status. For 2018, the standard deductions are: **STANDARDDEDUCTION_TAXYEAR_DEFINITION**
