A Guide to Quarterly Taxes and 2023 Deadlines

Updated: Jun 15, 2023

As a small business owner, it's essential to understand what quarterly taxes are, who has to pay them, and what the deadlines are. The income tax system is a pay-as-you-go system. This means that taxes are paid as income is earned. Most individuals pay taxes as they earn income by having their employers withhold taxes from their paychecks and sending the payments directly to the IRS on their behalf. However, for self-employed individuals, freelancers, and business owners who are not subject to regular payroll tax withholdings, quarterly tax payments are required by the IRS.



Who Needs to Make Quarterly Tax Payments?

If you are self-employed, a freelancer, a contractor, or a small business owner, and you expect to owe $1,000 or more in taxes for the year, you are generally required to make estimated quarterly tax payments. If you are a salaried employee, you do not need to make quarterly tax payments because your employer withholds taxes from your paycheck throughout the year.


How Much Do You Need to Pay?

To calculate your quarterly taxes, you need to estimate your income and deductions for the year. You can use last year's tax return as a guide or estimate your income based on your current earnings. Then, subtract any deductions or credits you expect to qualify for to arrive at your taxable income. In short, the amount you need to pay depends on your income, deductions, and credits. You can use the IRS Form 1040-ES to calculate your estimated tax liability for the year and determine your quarterly payments. You can also contact us at CPA by Choice for assistance.
