As a business owner, it is important to understand your tax obligations at the federal, state, and local levels. Doing so will help ensure you file your taxes accurately and make required payments on time. Importantly, the business entity structure (e.g., LLC, S-Corp, Corporation) you choose when starting a business will determine what taxes you will pay and how you pay them.
All businesses, except partnerships, must file an annual income tax return. Partnerships file an annual information return (IRS Form 1065) to report income, gains, losses, and other important tax information. The specific type of return required to be filed depends on your business entity structure For more information about the tax consequences associated with the various business entity structures, see the Business Entities category in the FAQs below.
Additionally, almost every state imposes a business or corporate income tax, though each state and locality has its own unique tax laws. Check out the Small Business Administration's state-by-state lookup tool to find out the business income tax requirements in your state or territory.

Review the IRS chart below to determine whether you are required to file a federal income tax return. Remember, you may want to consider filing even if you are not required to do so. Why? Because you may be entitled to receive a refund due to tax credits such as the Earned Income Tax Credit.

The 2018 Tax Cuts and Jobs Act overhauled the Internal Revenue Code and set forth the following seven tax brackets for ordinary income: 10%, 12%, 22%, 24%, 32%, 35% and 37%. The U.S. follows a progressive tax system, which means a taxpayer's tax rate increases as his or her income increases.
For tax year 2021, the top ordinary income tax rate remains 37% for single taxpayers with incomes greater than $518,400 ($622,050 for married couples filing jointly). The other rates are:
Single Filers
Married, Filing Jointly
Marginal Rates
The term "marginal tax rate" refers to the rate you pay at each level (or bracket) of income. Increments of your income are taxed at different rates. For example, if you're a single taxpayer with taxable income of $90,000 in 2019, then the first $9,875 you made is taxed at the 10% rate, the income between $9,876 and $40,124 is taxed at 12%, the income between $40,125 and $85,524 is taxed at 22%, and the remaining income between $85,525 and $90,000 is taxed at 24%. Thus, even though a portion of your income is subject to the higher 24% marginal tax bracket, your effective tax rate is approximately 17.5%.
Marginal vs. Effective Tax Rate
The marginal tax rate is the statutory rate, as listed above, while the effective tax rate (which will generally be lower) is the actual rate you pay on your taxable income after accounting for deductions and certain tax credits. Check out TaxAct's 2019 Tax Bracket Calculator to quickly determine your marginal and effective tax rates.

Capital gains are the profits received from the sale of certain investment assets (e.g., stocks, land, a business). There are two types of capital gains: long-term and short-term.
Long-term capital gains occur when you make a profit from the sale or transfer of an asset that you've held for more than a year. The profits are taxable, but at a very preferential rate---see the chart below for the 2020 capital gain tax rates for single filers and those who are married filing jointly.
Single Filers
Married, Filing Jointly
Short-term capital gains occur when you sell or transfer an asset that you have held for one year or less. Short-term capital gains are taxed at ordinary income rates, so no preferential tax treatment applies.
Key Takeaway: It can be extremely beneficial from a tax standpoint to invest in assets and hold them for at least a year and one day before selling or disposing of them to take advantage of the long-term capital gains tax rates.

According to the IRS, you must keep records such as receipts, canceled checks, and other documents (W-2s, 1099s, invoices, etc.) that support an item of income, a deduction, or a credit appearing on a tax return for as long as those records may become material in the administration of any provision of the Internal Revenue Code. Basically, you are required to keep all records that support the amounts reported on your tax return until the time limitations for that return expires (usually 3 years).
Generally, records must be kept for at least 3 years, but there are certain situations that require they be kept for longer.
Also, if you need information from a previously filed tax return, you may either:
Request a copy of your tax transcript by submitting a Form 4506-T (Request for Trascript of Tax Return); or
Create an account on IRS.gov to view a history of your account transcipts (visit https://www.irs.gov/payments/view-your-tax-account).
For more information, see MyTaxRights's Recordkeeping topic and IRS Topic No. 305 (Recordkeeping).

It is important to file your tax return on time even if you are unable to fully pay your tax debt because the IRS assesses penalties for late filing.
First, determine how much you can pay. Second, choose the payment option that best fits your situation. Common payment scenarios are listed below.
(A) If you can pay the full amount immediately:
You can pay with an electronic funds transfer or with a credit or debit card, or with a check by mailing it to the address listed on your bill or bringing it to your local IRS office.
(B) If you cannot pay the full amount immediately, but can pay it within 120 days:
If you cannot pay in full immediately, the IRS offers additional time (up to 120 days) to pay in full. It is not a formal payment option, so there is no application and no fee, but interest and any penalties continue to accrue until the tax debt is paid in full. For information about this option, call the IRS toll-free at 1-800-829-1040 (individuals) or 1-800-829-4933 (businesses).
(C) If you want to make monthly payments to pay off your tax debt:
You can ask for an Installment Agreement, which is a fixed monthly payment. This is a formal agreement with the IRS, and involves an application process and fees. For more information on IRS Installment Agreements, visit the IRS's Additional Information on Payment Plans page.
(D) If you are unable to pay off the full tax debt:
An Offer in Compromise allows you to pay less than the full amount you owe.
For the IRS to consider an Offer in Compromise, you must apply, and must generally pay certain fees and a portion of the debt. You must then file tax returns and make payments on time for five years after the IRS accepts your offer.
(E) If you are unable to make any sort of payment:
The IRS understands there may be times when you cannot pay a tax debt due to your current financial situation. If the IRS agrees that you cannot pay your taxes and pay your reasonable living expenses, it may place your account in a status called Currently Not Collectible. The IRS will not try to collect payment from you while your account is in Currently Not Collectible status, but the debt does not go away, and penalties and interest continue to grow.

Estimated tax payments refer to the process by which certain indiviudals and businesses periodically pay their share of taxes on the income they receive or earn.
Taxpayers are generally required to pay taxes on their income as its received or earned. For most employees, these taxes are paid automatically through what is known as tax withholding---the process by which an employer withholds a prefixed amount from an employee's wages to cover the employee's payroll tax obligations (e.g., income tax, social security tax, and Medicare tax). However, if you are self-employed or an independent contractor, then you will generally need to make estimated tax payments to the IRS because you are not subject to employee tax withholding. Sole proprietors, partners, and S corporation shareholders may also need to make estimated tax payments.
Who is Required to make Estimated Tax Payments?
Taxpayers generally must make estimated tax payments throughout the year if they expect to owe $1,000 or more in taxes when they file their next tax return. Corporations generally must make these payments throughout the year if they expect to owe $500 or more on their next tax return.
Estimated Tax Payment Schedule
Estimated tax payments are due at four different periods throughout the year:
April 15th (for the period January 1st - March 31st);
July 15th (for the period April 1st - May 31st);
October 15th (for the period June 1st - August 31st); and
January 15th (for the period September 1st - December 31st).
Note, If you do not pay enough tax by the due date of each payment period, you may be charged a penalty even if you are due a refund when you file your income tax return.
For more information on estimated tax payments, including how to make the payments, see MyTaxRights's article entitled Some taxpayers may be required to make estimated tax payments.

You can use the IRS Withholding Calculator to help determine the right amount of tax that should be withheld from your paycheck. The amount of income tax your employer withholds from your regular pay depends on the following two things:
The amount you earn; and
The information you give your employer on IRS Form W–4 (Employee’s Withholding Allowance Certificate).
If your employer is not withholding the proper amount to cover your annual tax obligation, you may need to complete a new IRS Form W–4 to change the amount being withheld.
- 08
Federal law requires that an employer issue a Form W-2 to each of its employees no later than January 31st. If you have not received a Form W-2 by January 31st, the IRS advises that you first contact your employer to try to resolve the issue. If your attempts to resolve the issue have not worked by the end of February, consider contacting the IRS to initiate a Form W-2 complaint. You can call the IRS toll free at (800) 829-1040 or make an appointment to visit an IRS Taxpayer Assistance Center (TAC).

The Internal Revenue Code defines gross income as all income from whatever source derived, including (but not limited to) the following items:
Compensation for services, including fees, commissions, fringe benefits, and similar items;
Gross income derived from business;
Gains derived from dealings in property;
Interest;
Rents;
Royalties;
Dividends;
Annuities;
Income from life insurance and endowment contracts;
Pensions;

Constructively-received income
Generally, any income that is available to you is subject to tax regardless of whether the income is actually in your possession. Income is considered "constructively-received" when an amount is credited to your account or made available to you without restriction. You do not need to have possession of it. If you authorize someone as your agent to receive income for you, you are considered to have received it when your agent receives it. Income is not considered constructively-received if your access to it is subject to substantial restrictions or limitations.
Assignment of income
An assignment of income occurs when you agree (through a contract) that a third-party can receive income for you. If you assign all or part of your income to a third-party, you must include the assigned amount as part of your gross income when the third-party receives it. For example, if you and your employer agree that part of your salary is to be paid directly to your former spouse, then you must include that amount in your income when your former spouse receives it.
Prepaid income
Prepaid income, such as compensation for future services, is generally included as part of your gross income in the year you receive it. However, if you use an accrual method of accounting, you can defer prepaid income you receive for services to be performed before the end of the next tax year. In this case, you include the payment as part of your gross income as you earn it by performing the services.

Yes.
Generally, income received from any source is taxable. Thus, tips received by taxpayers are considered income and subject to federal income tax. Some taxpayers mistakenly believe they are not required to report their cash tips to the IRS, which can lead to a lot of trouble during tax time.
For more information on the tip income reporting requirements, see MyTaxRights's article entitled Taxpayers must report tip income to the IRS, including cash tips and the IRS's Tip Recordkeeping & Reporting page.

Yes. Taxpayers should be aware of the following common penalties.
Failure-to-File Tax Return
The IRS may impose an addition to tax penalty against a taxpayer for the failure to file a required tax return, unless the taxpayer can show that the failure was due to reasonable cause and not willful neglect. The initial penalty amount is 5% of the tax liability shown on the return plus an additional 5% for each month the failure to file continues, up to a total penalty amount of 25% of the tax liability. 26 U.S.C. § 6651(a)(1). The 5% monthly penalty amount is reduced by the amount of the failure-to-pay penalty amount (0.5%) for any month that both penalties apply simultaneously; thus, the maximum penalty amount when these two penalties apply cannot exceed 5% per month.
Failure-to-Pay Tax
The IRS may impose an addition to tax penalty against a taxpayer for the failure to pay the amount shown on a tax return, unless the taxpayer can show that the failure was due to reasonable cause and not willful neglect. The initial penalty amount is 0.5% of the tax liability shown on the return plus an additional 0.5% for each month the failure to pay continues, up to a total penalty amount of 25% of the tax liability. 26 U.S.C. § 6651(a)(2).
Failure-to-Pay Estimated Income Tax
The IRS may impose an addition to tax penalty against a taxpayer for the failure to pay estimated income tax. 26 U.S.C. 6654(a). The penalty is determined by applying the applicable interest rate (known as the “underpayment rate”) to the tax amount that should have been paid (known as the “underpayment of estimated tax”) for the duration of the underpayment period. The applicable interest rate is determined on a quarterly basis and can be found in 26 U.S.C. § 6621. Note, though, the penalty does not apply if a taxpayer: (1) retired after reaching age 62, or became disabled, in the taxable year or the preceding taxable year; and (2) the underpayment was due to reasonable cause and not willful neglect. See 26 U.S.C. 6654(e)(3)(B).
