Individuals and corporations must pay estimated taxes on income that is not subject to withholding, which includes income from self-employment, interest, dividends, alimony, rent, gains from the sale of assets, prizes, and awards. Estimated taxes are paid in installments (usually quarterly) and if left unpaid, or paid late, you or your business will face interest and penalties.

What forms report this information?

For individuals, Form 1040ES is where estimated taxes are reported and paid, and for C corporations, Form 1120W (generally paid electronically using the Federal EFTPS system)

Do the due dates change periodically?

Not exactly. The only reason the first estimated tax payment is due April 18th for individuals this year is because of Emancipation Day celebrated in the District of Columbia (falls on April 15th this year). Normally, the first individual due date would be April 15th, in line with the due date of form 1040. Similarly, fourth quarter payments are due January 17th this year because the 15th falls on a Sunday, and is followed by Martin Luther King Jr. Day on Monday, January 16th.

It is important to comply with your tax obligations; you do not want to be tacked with unwanted penalties that will affect your payments at the time of filing.
