Income Tax Calculator
Tax Amount Owe for 2017: $1
* The purpose of our Income Tax Calculator is to try to bridge the gap between the complexity of U.S. tax law, while providing a relatively simple to use calculator that attempts to condense a large assortment of complex tax paperwork. As a result, many assumptions are made, and though our calculators are developed with care in an attempt to reach the highest standards of quality possible, calculations should be considered estimates, and not perfect representations for all given situations.
In order to find an estimated tax refund or due, it is first necessary to determine a proper taxable income. It is possible to use the W-2 forms to help fill out the inputs. Relevant W-2 boxes are displayed to the side if they can be taken from the form. Taking gross income, subtract deductions and exemptions such as contributions to a 401(k) or pension plan. The resulting figure should be the taxable income amount.
Other Taxable Income
Interest Income—Most interest will be taxed as ordinary income, including interest earned on checking and savings accounts, CDs, and income tax refunds. However, there are certain exceptions such as municipal bond interest, and private-activity bonds.
Short Term Capital Gains/Losses—profit or loss from the sale of assets held for less than one year. Taxed as normal income.
Long Term Capital Gains/Losses—profit or loss from the sale of assets held for one year or longer. Taxation rules applied are determined by ordinary income marginal tax rate.
Ordinary Dividends—All dividends should be considered ordinary unless specifically classified as qualified instead. Ordinary dividends are taxed as normal income.
Qualified Dividends—there are many stringent measures in place for dividends to be legally defined as qualified in order for them to be taxed at lower rates than ordinary dividends. The range of taxation can be as high as 23.8% for the highest tax bracket to tax-free for the lowest tax bracket.
Passive Incomes—Making the distinction between passive and active income is important because taxpayers can claim passive losses. Passive income generally comes from two places, rental properties or businesses that don't require material participation. Any excessive passive income loss can be accrued until used or deducted in the year the taxpayer disposes of the passive activity in a taxable transaction.
Broadly speaking, exemptions aim to reduce or even eliminate tax liability. For instance, charities and religious organizations are generally exempt from taxation. On a more personal level, starting in 2018, personal and dependent exemption deductions are eliminated.
Tax deductions arise from expenses and help lower tax bills by reducing how much of gross income is subject to taxes. The following descriptions are basic summaries, please consult the official IRS website for more detailed information regarding precise calculations of tax deductions.
Examples of deductions include:
State and local tax—Federal deductions of state and local tax can be either income tax or sales tax, but not both. Taxpayers in states that don't have income tax are probably better off using their sales tax for deduction.
Mortgage interest—This can apply to a regular mortgage up to a certain limit, which is $750,000 (or $375,000 if married filing separately), for a main residency, a second mortgage, a line of credit, or a home equity loan. Loans that aren't secured debt on a home are considered personal loans, which are not deductible. The IRS defines a "home" as anything from a house, condo, co-op, mobile home, boat, or RV.
Charitable donations—Only donations to qualified charities can qualify as tax deductions. Handouts to the homeless or payments to local organizations that aren't classified as a nonprofit by the IRS cannot be tax deductible.
Business expenses—These involve many different rules and are a bit complex. As a result, it may be a good idea to consult official IRS rules relating to the deduction of business expenses. To summarize, any cost that is associated with carrying on a business or trade can usually be deductible if the business operates to make a profit; however, it must be both ordinary and necessary. Try to make the distinction of business expenses from other capital or personal expenses, and expenses used to determine the cost of goods sold.
Medical expenses—Any expense paid for the prevention, diagnosis, or medical treatment of physical or mental illness or any amounts paid to treat or modify parts or functions of the body for health can be deducted. Medical expenses for cosmetic purposes do not qualify.
If premiums are paid with after-tax dollars, deductions are limited only to the expenses that exceed 10% of adjusted gross income, and 7.5% for anyone 65 and older.
Standard vs. Itemized Deductions
Instead of painstakingly itemizing many of the possible deductions listed above, there is an option for all taxpayers to choose the simpler standard deduction - which 70% of the population opts to do. The annual standard deduction is a static amount determined by Congress, usually to best keep up with inflation. In 2018, it is $12,000 for single taxpayers and $24,000 for married taxpayers filing jointly. The calculator automatically determines whether the standard or itemized deduction (based on inputs) will result in the largest tax savings and uses the larger of the two values in the estimated calculation of tax due or owed.
Congress formulates and hands out tax credits to taxpayers they deem are making decisions that are beneficial to society. For taxpayers, they help to lower tax bills by directly reducing the amount of tax owed. For instance, a $1,000 tax credit will reduce a certain tax liability of $12,000 to $11,000. It is important to make the distinction between nonrefundable and refundable tax credits. Nonrefundable credits can reduce total tax liability to $0, but not beyond $0. Any unused nonrefundable tax credits will expire and cannot be carried over to the next year. On the other hand, refundable tax credit amounts give taxpayers entitlement to the full amount, whether their tax liability drops all the way down to below $0 or not. If below $0, the difference will be given as a tax refund. Refundable tax credits are less common than nonrefundable ones.
Due to the complexity of income tax calculations, our Income Tax Calculator only includes input fields for certain tax credits for the sake of simplicity. However, it is possible to enter these manually in the "Other" field. Just be sure to arrive at correct figures for each tax credit using IRS rules. Also, the following descriptions are basic summaries. Please consult the official IRS website for more detailed information regarding precise calculations of tax credits.
Examples of some common tax credits are separated into the four categories below.
Earned Income Tax Credit—This is one of the most prominent refundable tax credits around and is generally only available to low or moderate-income households making up to around $50,000 depending on situations. For the most part, these are refundable.
Foreign Tax Credit—This is a non-refundable credit reduces the double tax burden for taxpayers earning income outside the U.S.
Child Tax Credit—It is possible to worth up to $2,000 per child for 2018, within which $1,400 is refundable. The child tax credit start to phase out once the income reach $200,000 ($400,000 for joint filers).
Child and Dependent Care—About 20% to 35% of allowable expenses up to $3,000 for each child under 13, a disabled spouse or parent, or another dependent care cost can also be used as a tax credit. Like many other tax credits, this one is also based on income level.
Adoption Credit—The non-refundable tax credit for qualified expenses to certain level for each child adopted, whether via public foster care, domestic private adoption, or international adoption.
