How An Estimated Tax Calculator Can Help Calculate Quarterly Taxes?

Q: Should I pay self-employment taxes quarterly or yearly?

Usually, if you anticipate owing the IRS over $1,000 in self-employment tax, you pay these taxes quarterly.

Q: Who has to pay quarterly taxes?

Any 1099 earner—be it a freelancer, gig worker, or small business owner—owing more than $400 in a tax year faces SECA taxes. If the total tax exceeds $1,000, quarterly payments apply.

Q: How much is quarterly taxes?

Your quarterly tax amount is determined by your net income (gross income minus deductions). Using a quarterly tax calculator simplifies finding the exact figure.

Q: What form should I use to pay quarterly taxes?

You should fill out Form 1040-ES for making estimated quarterly tax payments. While the payments have to be made every quarter, you only need to fill out this form once.

Q: What safe harbor percentage should I pay for estimated taxes?

If you’re a single filer with an adjusted gross income (AGI) below $150,000, you should pay 90% of the current year’s tax amount. If you think your AGI will be over $150,000, you should pay 110% of last year’s tax amount.

Q: Is there a penalty for not paying estimated quarterly taxes?

You can get hit with a late penalty or the underpayment penalty if you fail to make quarterly tax payments on time. You can use a tax penalty calculator to calculate your total penalty fees.

Q: How to request a reduction of the tax penalty?

If you’re trying to waive your tax penalty, you can fill out Form 843. But you can only get these penalty fees waived if you already paid most of your tax payments earlier in the year, changed your filing status from or to married filing jointly, generated a lot more income in the later part of the year, or made all your federal estimated tax payments on time.

Q: How to increase W-2 withholding for estimated taxes?

After using a 1099 quarterly tax calculator to calculate your estimated taxes, you can actually avoid paying these taxes if you already have W-2 income. Simply fill out Form W-4 to ask your employer to increase your income tax withholding to cover your SECA tax liability.

Q: How to calculate my IRS payment plan?

You can get in touch with the IRS to extend your deadline to pay taxes. You should only request an extension if you think you can make the full payment within the agreed-upon timeframe.

Q: How to pay quarterly taxes?

You can make IRS estimated tax payments online, by mail, or wire transfer.

Who has to pay estimated taxes?

Self-employment tax (or SECA tax) needs to be paid by every 1099 employee who makes over $400 in income every year. The SECA tax is set at a rate of 15.3%, with 12.4% towards Social Security, and 2.9% for Medicare. However, SECA tax isn’t paid once a year like the federal income tax. The IRS taxes this income as it is earned, so this isn’t a problem for W-2 employees. Self-employed individuals are in charge of paying their own taxes, so they have to make these tax payments themselves. The IRS knows that self-employed income isn’t always the same every year. That’s why they allow taxpayers to make estimated payments every quarter. These payments will only have to be made if the tax owed crosses $1,000. This is also why freelancers, small business owners, gig workers and independent contractors use an estimated taxes calculator to find their earned income for the year rather than try to calculate it themselves.

How to calculate quarterly taxes?

So you know that estimated taxes have to be paid if the tax amount is over $1,000. But you might be wondering, “How much are estimated quarterly taxes?”, and if there’s a limit to how much tax you’ll have to pay. Unfortunately, there is not. If your income is over the threshold limit, you’ll have to pay SECA tax. And if you think you’ll make enough to owe over $1,000, you have to make the estimated tax payments. Apart from just calculating your owed tax, an estimated tax calculator can also find deductions you can claim. To calculate estimated tax, you’ll need to either enter the number of business expenses you’re writing off or choose what you are eligible to write off from a list of deductions.

A 1099 quarterly tax calculator can find deductions like health insurance premiums, advertising costs and internet expenses. To make the most of your tax savings, it's crucial to know which deductions apply to you as a 1099 employee. Explore a detailed breakdown below of deductible expenses across key categories such as Medical Deductions, Personal Vehicle Deductions, and Home Office Deductions to ensure you're not leaving any money on the table.

For example, you’re a part-time photographer who earned $8,000 in the months of January to April 2024, and expect to earn this amount each quarter throughout the year. You also spent $2,500 on travel expenses, equipment and vehicle mileage. This means your taxable income is $5,500 for the first quarter of 2024. You decide to use an estimated taxes calculator and find that your income for the whole year is approximately $27,500. Your total owed tax for 2024 is $4,208, or so you have to make estimated tax payments of $1,052 for 2024. Using your tax deductions has saved you $778. That’s the power of a quarterly tax calculator!

Infographic entitled How an Estimated Quarterly Tax Calculator Identifies Nine Tax-Deductible Business Expenses to Reduce Quarterly Taxes.

How to use an estimated tax calculator?

A quarterly tax calculator only needs a few pieces of information from you to estimate your tax amount. Think tax info like the state you live in, your filing status, your job, all the business expenses you want to write off and your income for the year. Certain estimated tax calculators (like FlyFin) can even find your tax deductions for you (like retirement contributions), making that step so much easier. If you live in New Jersey all year but are moving to another state at the end of the year, you should still enter your state as New Jersey because that is where all your income comes from. If you’re a full-time 1099 employee, you’ll need to total all your income sources to get your gross income. This means any money earned from gig work, freelancing, operating as a small business or an independent contractor. So, how do you find your estimated tax payments 2024? Use a quarterly tax calculator, enter all the basic tax information required and get a tax breakdown of your total liability and quarterly payments. Then, you just fill out Form 1040-ES and make your payments. If you’re paying estimated taxes online, you don’t need to file this form.

When is the deadline to pay quarterly taxes?

Usually, estimated taxes are paid on a quarterly basis. The payment deadline for each quarter falls on the 15th of the month (or the next working day). If you can't pay your taxes by the deadline, you will be fined by the IRS. You can face two types of penalties: the late penalty and/or the underpayment penalty. It’s pretty easy to avoid the late penalty fees. All you need to do is just pay your taxes on time. To avoid the underpayment penalty, you can do a couple of things. The first option is to use a quarterly tax calculator to pay 100% of the tax you owed last year. This is an easy way to avoid penalty fees, especially useful if your income does not fluctuate as often. The second option is to pay at least 90% of your tax liability for this year if you think you’ll make less than you did last year. As this is an estimated payment, you can pay a little over 90% as a safety net to avoid an underpayment penalty. This is known as the “safe harbor” rule. If your AGI (adjusted gross income) was over $75,000 as a single filer, you’d need to pay 110% of last year’s tax liability to fulfill the safe harbor rule. The last option is to pay 100% of your current year’s tax liability if you think your income is going to be more than what you made last year. A tax penalty calculator is a good tool to check whether you owe the IRS any penalties. You can also use this to calculate IRS payment plans. The penalties usually get higher the longer you put off paying your tax liability, so it’s a good idea to pay them off as soon as you can.

Consider the situation of Emma, a freelance copywriter who missed the deadline to file her returns and did not complete the required quarterly payments on time.

How to make estimated quarterly tax payments?

So you now know how to use an estimated tax calculator to make estimated tax payments 2024. Now let’s talk about how to pay estimated taxes. The easiest way to do this is to pay directly on the website. You can also use the IRS app, in both Spanish and English, IRS2Go to make your estimated tax payment. Another way to use the information you got from a quarterly tax calculator is to pay using the EFTPS. Also known as the “Electronic Federal Tax Payment System,” this method allows you to view all your previous tax payments and tax returns. You’ll need to make an account to register (don’t worry, it’s free), and you can start making your payments. If you’re looking to make these payments the old-fashioned way, you can still send the IRS checks. All you have to do is attach them to Form 1040-ES, which you’ll use to make these quarterly payments. Make sure to add your social security number or tax ID, mention the year of payment on the check and send it in without stapling it to the form. If you’re really old school, you can even call in and pay the IRS over the phone. You’ll need an EFTPS account to do this, and you’ll also have to pay them a small fee. If you don’t have an EFTPS account, you can still pay over the phone, but you’ll have to call a third-party provider. The last way to pay the IRS after calculating quarterly taxes is to increase your W-2 withholding amount. Now obviously, this will require you to already have W-2 income. So, W-2 employees have their income tax withheld from their employer. You can ask to have this amount increased to cover your quarterly tax payments with the help of Form W-4.
