Many taxpayers are required to pay taxes throughout the year instead of waiting until the annual tax return is filed. The IRS requires taxes to be paid as income is earned or received through either payroll withholding or estimated tax payments. If not enough taxes are withheld, taxpayers may owe penalties and interest even if they later receive a refund.
At Z Tax & Accounting, we assist individuals, self-employed professionals, business owners, landlords, investors, freelancers, farmers, and retirees with estimated tax planning and IRS Form 1040-ES calculations in Irving, Las Colinas, Dallas, Plano, Arlington, Fort Worth, Coppell, Grand Prairie, Richardson, Carrollton, Euless, Bedford, Grapevine, Farmers Branch, and across the United States.
IRS Form 1040-ES is used to calculate and submit estimated tax payments to the IRS during the year. Estimated taxes generally apply when income is received without sufficient federal tax withholding.
Estimated tax payments may cover:
Federal income tax
Self-employment tax
Alternative minimum tax (AMT)
Tax on investment income
Other applicable federal taxes
Proper estimated tax planning can help taxpayers avoid large tax balances and IRS underpayment penalties.
Taxpayers who receive income without automatic withholding may need to make quarterly estimated tax payments. Common examples include:
Self-employed individuals
Independent contractors and freelancers
Realtors® and brokers
Landlords and real estate investors
Investors receiving dividends or capital gains
Retirees with insufficient withholding
Taxpayers receiving alimony or other taxable income
Business owners and side-hustle operators
Farmers and fishermen
If you operate a business or receive significant non-payroll income, estimated taxes may be required.
Self-employed individuals generally must pay both income tax and self-employment tax throughout the year. Self-employment tax covers:
Social Security tax
Medicare tax
Because taxes are not automatically withheld from self-employment income, proactive planning is important to avoid IRS penalties and cash flow issues.
Estimated tax payments are due as follows:
January 1 to March 31 – April 15
April 1 to May 31 – June 15
June 1 to August 31 - September 15
September 1 to December 31 – January 15 of the following year
Note: If these due dates fall on a Saturday, Sunday or legal holiday, the payments are due the next business day.
You may not need to pay estimated taxes if all of the following apply:
You had no tax liability in the prior year
You were a U.S. citizen or resident alien for the entire year
Your prior tax year covered a full 12-month period
However, many taxpayers with self-employment or investment income still need quarterly tax planning and payment calculations.
The IRS may assess penalties if enough tax is not paid during the year through withholding or estimated payments. Penalties may apply if:
Quarterly payments are late
Not enough taxes are paid during the year
Estimated tax obligations are ignored
Generally, taxpayers may avoid penalties if they:
Owe less than $1,000 after credits and withholding, or
Pay at least 90% of the current year’s tax liability, or
Pay 100% of the prior year’s tax liability, whichever requirement applies
Special rules may apply for higher-income taxpayers, farmers, and fishermen.
Estimated taxes can be paid using several IRS-approved methods, including:
IRS Direct Pay
Electronic Federal Tax Payment System (EFTPS)
IRS Online Account
IRS2Go Mobile App
Mailing Form 1040-ES payment vouchers
Many taxpayers prefer EFTPS because it allows easy online payments and access to payment history.
