The calculators and tools on this page help you prepare and mail in your 2021 Taxes on paper before you print and mail them to the IRS and or State. Any of these tax calculators or estimators below can assist you in completing 2021 returns.

Tax Tip: If you owe taxes, prepare and file your current Tax Year even if you can't pay on time, as the IRS penalties to file late are higher than to pay late. Or, to put it simply: file your returns even if you can't pay anything! If you expect a tax refund with your 2021 return, you have until April 2025 to file your 2021 return; after that date, your 2021 tax refund will expire.

Are you supporting a parent, relative, girlfriend, boyfriend, or other person? Find out who your qualifying relative or dependent is on your 2021 Return. A qualifying relative does not necessarily have to be related to you, but you can never claim your spouse as your dependent.
Child and Dependent Care Tax Credit: If you have a child or another dependent on your tax return, find out if you are eligible for this credit. This credit can offset the costs of childcare of daycare.
To file a 2021 Tax Return or not, is that your question? You may be surprised! Filing a return might be beneficial for you even if you do not have to. Keep in mind you must file a 2021 Return by April 15, 2025, to claim your tax refund! After that, it's gone.
Were you single with one or more dependents or qualifying relatives during 2021? The head of household filing status might just be for you. This unique filing status comes with a higher standard deduction and other benefits if you qualify for it.
If your 2021 taxable income was at a certain level and you are at least 19, let the Earned Income Tax Credit work for you! For 2021, you can use your 2019 income if it was higher than your 2021 income. The credit may be increased if you have at least one qualified child. This is one of many tax credits eFile will calculate for you when you file your current year's taxes.
When preparing a tax return, you must choose which filing status to use. The "STATucator" tool will help you determine which filing status is for you: married jointly or separately, single, or head of household.
The "CHILDucator" tax tool will help you determine if your child or dependent qualifies you to claim the Child Tax Credit on your tax return.
