1040 Tax Calculator
1040 Tax Calculator Definitions
- Federal Income Tax Rates:
- Filing status
- Choose your filing status. Your filing status determines the income levels for your Federal tax rates. It is also used to determine your standard deduction, personal exemptions, and many deduction or credit phaseout income ranges. 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 for two years after the year of your spouse's death, as long as 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 any time 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
- Enter the number of dependent children that qualify for the child tax credit. In 2020, for each qualifying child you can receive up to a $2,000 tax credit. To qualify a child must be under age 17 at the end of the year. They must be either your child, one of your siblings or your foster child or a child of any of them (for example your grandchild). In addition, they must have lived with you for more than half of the year, not provide more than half of their own support and must be claimed as a dependent on your tax return.
- Wages, salaries, tips, etc.
- Enter your total of all wages, salaries, tips, etc. For this entry only enter the amount for the primary taxpayer, do not include your spouse. This is normally the amount shown on your W-2 form(s) in box 1 provided by your employer. You should also include any wages received as a household employee not reported on a W-2 (a W-2 may not have been provided if the amount was less than $2,000). It should also include any tips not reported to your employer - including allocated tips that appear on your W-2 form(s) box 8.
- Spouse wages, salaries, tips, etc.
- Enter your spouse's total of all wages, salaries, tips, etc. For this entry, only enter the amount for your spouse. This is normally the amount shown on your spouse's W-2 form(s) in box 1 provided by your spouse's employer. You should also include any wages received as a household employee not reported on a W-2 (a W-2 may not have been provided if the amount was less than $2,000). It should also include any tips not reported to your spouse's employer - including allocated tips that appear on your spouse's W-2 form(s) box 8.
- Taxable interest
- Enter your total taxable interest. This should also include your spouse's taxable interest if you are married filing jointly. This is normally reported to you either form 1099-INT or form 1099-OID.
- Tax-exempt interest
- This amount is only used to calculate taxable Social Security Benefits and Earned Income credit. If these are not part of your return, this entry will not change your results. Enter your (and your spouse's if married filing jointly) total tax-exempt interest reported to you (and your spouse if you are married filing jointly) on form 1099-INT or form 1099-OID. Also include any amounts on 1099-DIV reported as exempt interest dividends. Don't include any interest earned in an IRA, Health Savings Account, MSA or Coverdell education savings account. Tax exempt interest you enter here will not be included in the calculation of the Alternative Minimum Tax (AMT). If any of your tax-exempt interest is subject to AMT please enter it in the "Alternative minimum tax (AMT) income adjustments" entry field.
- Ordinary dividends (this includes any qualified dividends)
- Enter your (and your spouse's if married filing jointly) total dividends for the year. This amount is normally reported to you on form 1099-DIV. Note that your total ordinary dividends for the year will include as part of the total any qualified dividends received.
- Qualified dividends
- Enter your (and your spouse's if married filing jointly) total qualified dividends for the year. This amount is normally reported to you on form 1099-DIV. Qualified dividends are the portion of your total ordinary dividends subject to the lower capital gains tax rate. Qualified dividends are typically dividends paid by a corporation in which you own stock (or a mutual fund that owns stock in the corporation).
Qualified dividends also have a minimum holding period of the underlying stock. For common stock dividends to be considered qualified dividends, you need to have owned the stock for at least 60 days during a 121 day period that starts 60 days before the ex-dividend date. The same rule applies for preferred stock but the holding period is 90 days during a 181-day period starting 90 days before the ex-dividend date.
Stock you own directly, not through a mutual fund or exchange traded fund, will report qualified dividends without regard to your holding period. If you bought or sold the stock during the year, you will need to determine if your ownership of the underlying stock meets the holding requirement.
Mutual funds and exchange traded funds will report qualified dividends with regard to their holding period of a stock owned by the fund. However, if you bought or sold fund shares during the year you will need to apply the same holding requirements to fund shares you own (or owned) as you would to a common stock. If you do not meet the holding requirement, qualified dividends reported to you by your fund should not be included as qualified dividends on your tax return.
- Taxable refunds of state and local income taxes
- If you did not itemize your deductions in the previous year, or you itemized deductions but elected to include sales taxes (instead of income taxes) this amount will be $0 regardless of any refund you received. Otherwise, the amount of your refund is taxable to the extent in which the over payment decreased your taxable income in previous year.
- Alimony received
- Enter the amount you received as spousal maintenance or alimony. Please note that a divorce or separation agreement executed after December 31st, 2018 is not considered income by the spouse receiving the payment. An amount should be entered only if the agreement was executed on or before December 31st, 2018.

- Taxable IRA distributions
- Enter any IRA distributions that are taxable. This would normally include distributions from a Traditional IRA, simplified employee pension (SEP) IRA, or a SIMPLE IRA. This also includes conversions of any of these IRA accounts to a ROTH IRA. If in previous years you made any contributions to your Traditional, SEP, or SIMPLE IRA that were not tax-deductible, some of your distribution may not be subject to tax. See form 8606 and its instructions for tax treatment in any of these situations.
Do not include any SEP, SIMPLE or Traditional IRA distributions that were rolled over to a Traditional IRA account. Do not include Roth to Roth rollovers or qualified ROTH IRA distributions.
- Taxable pensions and annuity distributions
- This is the taxable portion of payment made by a pension or an annuity. This also includes distributions from Traditional 401(k), 403(b) and governmental 457(b) plans. Generally speaking, if you did not pay for an annuity or pension yourself, or if all contributions were made with pre-tax money, then all distributions will be fully taxable. If you purchased an annuity with after-tax money (for example from your personal savings NOT a retirement account), distributions from the annuity will have the taxable portion reduced by the amount paid for the annuity. This reduction in taxability is spread out over the remaining projected lifetime of the annuity owner. See 1040 instruct.

This is automatically calculated based on all income entered as wages, salaries, tips, etc., all income entered as Business income or loss (Schedule C & E subject to self-employment taxes) and Farm income (Schedule F).
- Net Investment Income Tax (NIIT) (Form 8960)
- Investment income is subject to the Net Investment Income Tax (NIIT) when you have net positive investment income. Net investment income is total of all investment income, subject to the tax, where losses can offset gains in any given year. Any business income or loss that is subject to Self-Employment taxes is never considered investment income neither is business income from organizations where you actively participate (such as many S Corporations and Partnerships). The tax is 3.8% for all amounts above income thresholds for your filing type.

- Total of all Federal income taxes withheld for the year. This would typically be reported to you on form W-2 for employment wages and form 1099 for other income.
- Additional child tax credit (Form 8812)
- If you qualify for the child tax credit and were limited on taking the full credit, you may be eligible for this additional refundable credit. This additional credit is considered refundable because it is 'refunded' or paid to you even if you don't have enough income taxes to offset the credit (it will result in a total income tax bill for the year that is negative). In 2020 the refundable credit is limited to $1400 per child.
- Earned Income Credit (EIC)
- Earned Income Credit (EIC) is a tax credit available to low income earners. In some cases the EIC can be greater than the total income taxes owed for the year. This provides an income tax refund to families that may have little or no income tax withheld from their paychecks. This calculator will determine if you qualify for the Earned Income Credit, and if so, how much.
- Number of qualifying children
- Enter the number of children in your family that qualify for the Earned Income Credit (EIC). The IRS has a set of three requirements that must be met to have a child considered qualified.
- Your relationship to the child must be:
- Son, daughter, stepchild, eligible foster child, or a descendant (for example, your grandchild) of any of them, or
- Brother, sister, half brother, half sister, stepbrother, stepsister, or a descendant of any of them (for example, your niece or nephew).
- Age of your child must be:
- Under age 19 at the end of 2020
- A full-time student under age 24 at the end of 2020, or
- Permanently and totally disabled at any time during 2020, regardless of age.
- Be younger than the person claiming the child
- Not have filed a joint return other than to claim a refund
- Your child must have lived with you in the United States for more than half of 2020.
- Your relationship to the child must be:
- Earned income
- This is any income from wages, salaries, tips or any other earned income that is taxable. Do not include any non-taxable benefits in this total. Also include any earnings from farms, farm partnerships or businesses that did not require payment of self-employment taxes. Do not include any scholarships, penal income, annuity or pension income.
- Scholarships, penal & retirement income
- If you received income from any of these sources, it does not qualify for the Earned Income Credit. Your eligible Earned Income is reduced by this amount.
- Non-taxable combat pay
- If you received any non-taxable combat pay, the IRS allows you choose whether to figure your EIC with or without this pay included. This calculator will automatically choose the option that produces the highest EIC.
- Are you (or spouse if married) between the ages of 25 and 65?
- Check this box if you or your spouse will be 25 to 65 years old at the end of the year. To qualify for the Earned Income Credit, either you or your spouse (if you are married) must be at least 25 years old and no greater than 65 years old at the end of the year. This rule only applies to people without any children. Your response is not used if you have 1 or more qualified children.
- Can you (or spouse if married) be claimed as a qualifying child of someone else?
- You cannot be a qualifying child of another person and receive Earned Income Credit. If you meet the requirements to be a qualifying child of your parents based on the EIC rules, you are unable to claim any EIC for yourself. This is the case even if your parent or parents do not qualify for EIC and whether or not you have any qualifying children of your own.
- Have you (and spouse if married) lived in the U.S. for at least six months?
- Check this box if you (and your spouse if married) lived in the United States for more than six months of the year. You must have lived in the U.S. for at least six months and one day during the current year. This only applies if you do not have any qualified children. For military personnel, you are able to include any time spent on extended deployment as living in the U.S.
