Learn moreVery few people look forward to Tax Day. Once April rolls around, taxpayers frantically pull out W-9s and other tax forms to determine whether they owe taxes or will be paid a refund. If you’re an independent contractor or are self-employed, filing your taxes will look a little different. You might have to partake in this event four times a year. Learn the ins-and-outs of filing quarterly taxes, who they apply to, and how to estimate your tax payments.
Estimated quarterly taxes are payments that are made four times a year for individuals who haven’t had withholdings taken by an employer. This means they earned their income from being self-employed. Normally, taxes are paid as you get paid. When you receive a paycheck, taxes are deducted from your gross income. You’re then paid the remainder. When you’re self-employed, this isn’t the case. You must deduct their taxes on their own accord. You’ll have to estimate your tax liability and pay it over the year, instead of one full payment before Tax Day.
Quarterly taxes fall under two categories:
After the final payment is due at the end of year, you’ll still receive a tax return. The return will show the total payments made against the final tax liability. If the tax liability has been paid in full or overpaid, you’ll receive a refund. If money is owed against the tax liability, you’ll have to pay the remaining balance.
Quarterly taxes typically apply to people who are self-employed or earn a substantial amount of income outside of their employer. The IRS specifies that you need to pay estimated tax payments if you match the following criteria:
Individuals who are self-employed include freelancers, independent contractors, business owners, seasonal staff, and temporary workers. If you fall under any of these categories, review your withholding and refundable credits and estimate your federal income taxes to determine if you need to estimate quarterly tax payments. Individuals exempt from estimated quarterly tax payments include U.S. citizens and resident aliens who had no tax liability in the previous year.
To calculate your quarterly payments, you first need to calculate your tax liability for this year. Include your individual income tax, self-employment tax, and any additional taxes. Then you need to divide it by four to separate your liability into four payments. Estimated taxes can be calculated using the IRS’ Estimate Tax Worksheet. Individual filers use Form 1040-ES. Corporations use Form 1120-W.
For example, let’s say Marianne owns an eyebrow threading business and she estimates she will make $100,000 this year. After estimating her total income, Marianne considers the deductions she plans to claim, which total to $15,000. This brings her Adjusted Gross Income (AGI) to $85,000. Now that she knows her AGI, she can calculate her income and self-employment tax. The tax rate for single filers making $85,000 a year is 22%. You multiply her income by the tax rate (85,000 x 0.22), which brings her income tax liability to $18,700. The self-employment tax is 15.3%. You multiply this by Marianne’s income ($85,000 x .153) which brings her self-employment tax to $13,005. You add both tax estimates together, which equals $31,705, and divide it by four to calculate each estimated quarterly tax payment. For Marianne, this means making four payments of $7,926.25.
Quarterly deadlines for tax payments change year to year. For 2023-2024, the tax due dates are:
