I'm concerned because my check payment to the IRS has not been cashed yet. What should I do?

You can call (800) 829-1040 and ask an IRS representative if the payment has been credited to your account. If it has not and the check has not cleared your financial institution, you may choose to place a stop-payment on the original check and send another payment.

The partners may need to pay Estimated Tax Payments using Form 1040-ES.

How do I know if I have to file quarterly individual estimated tax payments?

Estimated tax payments can be used to pay Federal income tax, self-employment tax, and household employment tax. To estimate if you need to pay tax on income not subject to withholding or on other income from which not enough tax is withheld, you need to calculate if the total tax you'll owe on your annual income tax return will be covered by the amount of tax you have already had either:

Do self-employment taxes need to be paid quarterly or yearly?

Self-employment tax is paid by making quarterly estimated tax payments which include both income tax and social security tax.

When are the quarterly estimated tax returns due?

Your first estimated tax payment is usually due the 15th of April. You may pay the entire year's estimated tax at that time, or you may pay your estimated tax in four payments. The four payments are due April 15th, June 15th, September 15, and January 15th of the following year.

If the due date for making an estimated tax payment falls on a Saturday, Sunday, or legal holiday, the payment will be on time if you make it on the next day that is not a Saturday, Sunday, or legal holiday. For example, a payment due Saturday, January 15, 2005 will be on time if you make it by Tuesday January 18, 2005. Note: Monday January 17, 2005 is a legal holiday.

If I anticipate a sizable capital gain on the sale of an investment during the year, do I need to make a quarterly estimated tax payment during the tax year?

If you first receive income subject to estimated tax during a period other than the first quarter, you must make your first payment by the due date for the period the income is received. You can pay your entire estimated tax by the due date for the period the income is received, or you can pay it in installments by the due date for that period and the due dates for the remaining periods.

If you are making estimated tax payments you can increase your quarterly estimated tax payments or increase your Federal income tax withholding to cover the tax liability. If you have the proper amount withheld you may not be required to make estimated tax payments nor have to file Form 2210 (PDF), Underpayment of Estimated Tax by Individuals, Estates and Trusts, with your tax return (as you would if you just increased the remaining estimated tax payments). If you wait and make increased estimated tax payments in the later quarters, you would have to file Form 2210 with your tax return because we do not know when you received the income. Since you really did not receive the income evenly throughout the year, you have to tell us when the income was received by filing Form 2210.

I am self-employed. How do I report my income and how do I pay Medicare and social security taxes?

Your self-employment income is reported on Form 1040, Schedule C (PDF), Profit or Loss from Business, or on Form 1040, Schedule C-EZ (PDF), Net Profit from Business.

Your Medicare and social security taxes are reported on Form 1040, Schedule SE (PDF), Self-Employment Tax.

As a self-employed person, you pay your Medicare and social security taxes the same way you pay your income taxes. If you expect to owe less than $1,000 in total taxes, you can pay them when you file your income tax return. If you expect to owe $1,000 or more in total taxes, you will need to make estimated tax payments. These payments are made quarterly using Form 1040-ES (PDF), Estimated Tax for Individuals. You will need to figure these taxes at the beginning of the year. To learn about figuring and making estimated tax payments, please refer to Publication 505, Tax Withholding and Estimated Tax.

I just started a small business and want to know if I have to file my income taxes quarterly or at the end of the year?

The Federal Income Tax return is filed annually. As a self-employed individual, if after deducting withholding and credits you expect to owe $1,000.00 at the end of the year, you should make estimated tax payments on a quarterly basis. Form 1040-ES (PDF), Estimated Tax for Individuals, will assist you in determining if estimated tax payments are due and how they are paid.

When you file the income tax return at the end of the year, you include the income from the business on the return. The forms to be filed are Form 1040 (PDF), U.S. Individual Income Tax Return, Form 1040, Schedule C (PDF), Profit or Loss from Business Form 1040, Schedule SE (PDF), Self-Employment Tax. If estimated tax payments where made during the year, they will be claimed on the individual income tax return as payments. See Form 1040, Line 57.
