How To Calculate Estimated Quarterly Taxes

A big tax day is coming up. How to calculate estimated quarterly taxes? It’s tax day again. I think. You may know how to do it, but it’s really difficult to calculate estimated quarterly taxes.

The formula for estimated quarterly taxes is quite different from that of quarterly taxes. You may know the calculation of annual taxes, but you don’t know how to calculate estimated quarterly taxes. You may calculate them easily, but there are still some mistakes. So you’re thinking of calculating estimated quarterly taxes again?

What Are Estimated Tax Payments

Estimated tax payments are due on April 15 each year and are calculated based on your income and deductions for the year.

For instance, let’s say that your adjusted gross income is $50,000. That means that your taxable income is $48,500. However, the government has granted you a $10,000 tax break. So, if you are single, you will owe $3,865 in income tax.

If you do not pay your estimated tax payments, you will need to pay $4,700 to the IRS to make up for the difference between the $3,865 you already paid and the $10,000 tax break you still owe.

The IRS will use your information to calculate your estimated tax payments. The amount you will be taxed is determined by the percentage of your adjusted gross income greater than the standard deduction. So, if you are married, you can claim two exemptions. Each exemption reduces your taxable income by $2,200.

That means that your tax rate will be the amount left over after subtracting your standard deduction from your taxable income. So if you are married, your tax rate is 50%.

If you are single, your tax rate is 28.5% of your taxable income.

You will get a refund for the tax you paid if you have no dependents. If you do have children, they will be considered dependents. If this applies to you, you will get an additional refund for the amount you paid in estimated tax payments.

How To Calculate Estimated Quarterly Taxes

When it comes to planning your taxes, you need to do two things:

Prepare your quarterly taxes (also known as estimated quarterly taxes) and file your taxes.

Estimated quarterly taxes are used to estimate your total tax liability for the entire year, which is then used to file your final tax return. If you are self-employed, this is your estimated tax payment.

If you are a contractor, this is the same thing. You can use this amount to estimate the amount of money you will need to pay for taxes at the end of the year.

This is done by multiplying your monthly sales by the number of months in the year.

For example, if your monthly income is $3,000 and you are an employee, then your estimated tax payment for the year will be $54,000.

But if you are self-employed, your estimated tax payment for the year will be $78,000.

Your quarterly tax is calculated by adding your estimated tax payment for the year, along with any deductions you have taken.

For example, if your business has been deducting 30% of your income for rent, then you will also have 30% of your total tax liability deducted.

To figure out how much you will have to pay in quarterly taxes, add your total estimated tax payment for the year, along with any deductions you have taken, to your total income.

Let’s say you make $50,000, and your business has taken a $12,000 deduction. Then your total estimated quarterly tax payment will be $1,200.

In order to calculate your estimated quarterly taxes, add your total estimated quarterly tax payment to your total income.

How To Calculate Your Income Taxes

It’s quite easy to understand. But you need to pay attention to all details because, in most cases, the tax is not included in the price of goods and services.

The following calculation takes place every year on April 15, when you must file your income tax return.

Step 1. Calculate Your Earnings

Calculate your net monthly income using the following formula:

Net income = Gross monthly income – (Total deductions)

Gross monthly income = Total gross monthly income

Total gross monthly income = Monthly payment + Interest income + Other income

If the total monthly income is negative, set the value to zero.

Monthly payment = Interest + Other income

Interest income = (Number of interest payments) x (Interest rate)

Other income = (Other income) x (Proportion of total income)

Step 2. Calculate The Number Of Interest Payments

Calculate the number of interest payments you made during the current period based on the following formulas:

N = (12 * M) / 12


N = number of interest payments

M = Months from January 1 to April 15

Step 3. Calculate The Interest Rate

Multiply the average annual percentage rate of interest by the number of interest payments to get the monthly interest rate.

Step 4. Calculate The Total Annual Interest

Calculate the total annual interest by multiplying the monthly interest rate by the total number of months or by using the formula below.

Total annual interest = (12 * N) / 12


N = number of interest payments

Step 5. Calculate The Amount Of Interest Paid

Add the total annual interest to the total monthly payment to calculate the amount of interest paid.

Income taxes should be calculated separately for each individual income category, e.g., wage income, interest income, dividends, and capital gains.

In addition, you should subtract personal expenses that have been deducted from your monthly income. Personal expenses include items such as mortgage interest, rent, car, telephone bills, household expenses, education, and health care.

Personal expenses can be deducted only if they have been written off as a business expense on your tax return.

Finally, multiply the total income by your tax rate to calculate your income taxes.

To calculate your federal income tax, use IRS Tax Tables or software such as TurboTax, which includes a pre-filled form.

If you don’t have a tax professional to help you, you can also use a tax calculator online, such as the free tax calculator.

Step 6. Calculate Your Income Tax

Calculate your income tax liability by subtracting the income taxes you paid from your income.

Understanding The Difference Between Withholding And Estimated Quarterly Tax:

The IRS requires individuals to make estimated quarterly tax payments (QTIP) at the beginning of each calendar quarter to avoid the possibility of being assessed a penalty.

While most employers provide an estimate of the amount they expect to withhold from employees’ wages, the QTIP amounts are adjusted based on actual withholdings.

In addition to the quarterly QTIP payments, individuals who owe taxes must make estimated quarterly payments during each calendar year.

How To Calculate Estimated Quarterly Taxes In More Complicated Cases

Calculating and paying your quarterly estimated tax payments (EET) on time is important to avoid penalties and fines.

If you receive any of the following income sources and want to calculate your estimated tax payments, you should know how to do it.

1. Taxable Wages

Taxable wages are income you received during the year that you are required to pay taxes on. For example, you can have a taxable wage of $10,000 if you received this amount in one month, which was in April.

2. Business Income

Business income is money you earn from your business activity during the year. Your business must be active for the entire year to qualify for this income.

3. Capital Gains

Capital gains are the profits you make on selling a capital asset. Capital assets include real estate, stock, bonds, and other financial assets.

4. Long-Term Capital Gains

Long-term capital gains are any capital gains that you make from the sale of an asset that has been held longer than 12 months.

5. Passive Income

Passive income is any income that you do not actively work to earn. It includes investments such as stocks, bonds, mutual funds, annuities, rental property, royalties, and partnership distributions.

6. SBA Loans

Small Business Administration loans are loans you can apply for if you are self-employed or own a small business.

7. Investment Interest

Investment interest is any income you earn on your investments, such as bank accounts, certificates of deposit, bonds, and real estate.

8. Rental Income

Rental income is any income you earned from leasing out your personal property such as a car, apartment, or vacation home.

9. Social Security Benefits

Social security benefits are payments that you received in exchange for your past labor. They are paid out to you when you turn 65 or older or when you are disabled.

10. Unemployment

Unemployment is income you earned from a job that you were no longer working at because of unemployment.


It is possible to pay too much, it is possible to pay too little, but it is almost impossible to pay exactly right all of the time. The best you can do is to plan ahead and know that your estimated quarterly taxes are not guaranteed to be accurate. Calculating your quarterly estimates is a good place to start, but it’s important to factor in adjustments as you go along.
