Form 1040-ES: Estimated Tax for Individuals (2016)

What Form 1040-ES Is For

Form 1040-ES is the IRS form used to calculate and pay your estimated taxes throughout the year if you earn income that doesn't have taxes automatically withheld. Think of it as a way to pay your taxes in installments rather than facing a large bill when you file your annual return.

The form is specifically designed for income that doesn't have taxes taken out before you receive it. This includes money from self-employment (such as freelancing, consulting, or running your own business), rental property income, interest and dividends from investments, alimony payments, and similar sources. If you're receiving unemployment benefits or Social Security and choose not to have taxes withheld, you'll also need to use this form to make estimated payments.

The United States operates on a "pay-as-you-go" tax system, which means the government expects you to pay taxes throughout the year as you earn income, not just once a year when you file your return. Most employees never think about this because their employer handles it through paycheck withholding, but if you're self-employed or have significant income from other sources, you become responsible for managing these payments yourself.

When You’d Use Form 1040-ES

You need to use Form 1040-ES if you expect to owe at least $1,000 in taxes when you file your 2016 return, after subtracting any withholding and refundable credits. Additionally, you must make estimated payments if you expect your withholding and credits to be less than either 90% of your 2016 tax liability or 100% of what you owed in 2015 (whichever is smaller).

There are important exceptions to these rules. If you're a higher-income taxpayer—meaning your adjusted gross income for 2015 exceeded $150,000 ($75,000 if married filing separately)—you need to pay 110% of your prior year's tax to avoid penalties, not just 100%. Farmers and fishermen have different thresholds: they only need to pay two-thirds (about 66.7%) of their current year's estimated tax.

You don't need to make estimated tax payments if you had no tax liability for the full 12 months of 2015, were a U.S. citizen or resident alien all year, and your 2015 return covered a full year. Having "no tax liability" means your total tax was zero or you didn't need to file a return at all. IRS.gov

If you want to avoid making quarterly estimated payments altogether, you can increase the withholding from your paycheck, pension, or annuity by filing a new Form W-4 with your employer or Form W-4P for pensions. This strategy works well if you have both wage income and self-employment income.

Key Rules or Details for 2016

Estimated tax payments for 2016 are due on four specific dates: April 18, 2016 (for income earned January through March), June 15, 2016 (April through May income), September 15, 2016 (June through August income), and January 17, 2017 (September through December income). You don't have to make the January payment if you file your complete 2016 tax return and pay any balance due by January 31, 2017.

The IRS divides the year into payment periods, and you must pay enough during each period to avoid penalties. However, you have flexibility in how often you actually make payments—you can pay weekly, monthly, or any schedule you prefer, as long as you've paid enough by each quarterly deadline.

When mailing payments, the postmark date determines whether your payment is on time. If a due date falls on a weekend or federal holiday, the deadline moves to the next business day. You should make checks payable to "United States Treasury" and write "2016 Form 1040-ES" along with your Social Security number on the check. IRS.gov

Special rules apply to farmers and fishermen. If at least two-thirds of your gross income comes from farming or fishing, you can either pay all your estimated tax by January 17, 2017, or file your entire 2016 return by March 1, 2017, and pay the full balance. These taxpayers use 66.7% instead of 90% when calculating required payments.

If your name has changed due to marriage, divorce, or another reason, and you made estimated tax payments under your former name, you must attach a statement to your 2016 return explaining this. The statement should show all payments made and the names and Social Security numbers used. Be sure to notify the Social Security Administration of your name change before filing your return to prevent processing delays.

Step-by-Step (High Level)

Start by gathering your 2015 tax return to use as a reference point. The form includes a worksheet that guides you through estimating your 2016 income, deductions, credits, and tax liability.

Step One: Estimate your 2016 adjusted gross income

First, estimate your adjusted gross income for 2016. This includes all your expected income from all sources—wages, self-employment, interest, dividends, rental income, and anything else. If you're self-employed, you'll need to calculate your self-employment tax separately using the Self-Employment Tax and Deduction Worksheet included in the form. Remember to account for the deduction for self-employment tax when figuring your adjusted gross income.

Step Two: Subtract deductions and exemptions

Next, subtract either your itemized deductions or the standard deduction (whichever you plan to use). For 2016, the standard deduction is $6,300 for single filers or married filing separately, $12,600 for married filing jointly or qualifying widow(er), and $9,300 for head of household. These amounts increase if you're 65 or older or blind. Then subtract your personal exemptions—$4,050 per exemption for 2016.

Step Three: Figure your tax and other taxes

Use the Tax Rate Schedules included in Form 1040-ES to calculate your tax on the remaining income. Add any other taxes you expect to owe, such as self-employment tax or Alternative Minimum Tax. Subtract any tax credits you're eligible for, such as the child tax credit or education credits.

Step Four: Determine if you need estimated payments

The result is your total estimated tax for 2016. If you have any tax withholding from wages or other income, subtract that amount. What remains gets divided by four (or adjusted if you're starting payments mid-year) to determine your quarterly payment amounts.

Step Five: Complete vouchers and make your payments

Complete the payment voucher by printing your name, address, and Social Security number. Enter only the amount you're paying with that particular voucher—don't include any prior year overpayment you've applied. Detach the voucher and mail it with your check to the address listed for your state. IRS.gov

Common Mistakes and How to Avoid Them

One of the most frequent errors is underestimating your income, especially if you're self-employed and your income fluctuates. While it's impossible to predict exactly what you'll earn, make your best estimate and be prepared to adjust. The IRS allows you to recalculate and change your payments for upcoming quarters if your situation changes significantly. Complete a new worksheet and adjust your remaining payments accordingly.

Many taxpayers forget to account for self-employment tax when calculating their estimated payments. Self-employment tax covers Social Security and Medicare taxes that employers normally pay half of. For 2016, you owe 15.3% on net self-employment income up to $118,500, plus 2.9% on amounts above that. Don't overlook this substantial tax when making your calculations.

Another mistake is failing to make payments on time. Even if you're expecting a refund when you file your annual return, late estimated payments can still trigger penalties. Each payment period stands alone—you can't make up a missed payment by paying extra in the next quarter without potentially owing a penalty for the earlier period.

Taxpayers sometimes put the wrong amount in the payment box on the voucher. If you're applying a prior year overpayment to your estimated taxes, don't include that amount in the payment box—only enter the actual amount you're sending with that voucher. The IRS already knows about your overpayment from your previous return.

Using incorrect mailing addresses causes delays. The IRS has different processing centers for different regions, and estimated tax payments go to different addresses than annual returns. Always check the current form for the correct address based on where you live. Sending payments to a P.O. box requires using the U.S. Postal Service; private delivery services can't deliver to P.O. boxes.

If you receive income unevenly throughout the year—perhaps you're a seasonal business or receive large capital gains late in the year—you might unnecessarily overpay estimated taxes in early quarters. The IRS offers an "annualized income installment method" that lets you match payments more closely to when you actually earn income, potentially lowering or eliminating penalties. This requires filing Form 2210 with your return, but it can save money if your income is genuinely uneven.

What Happens After You File

The IRS processes your estimated tax payments and credits them to your account under your Social Security number. You'll report the total of all your estimated payments on your 2016 Form 1040 when you file your annual return in 2017. These payments reduce the amount you owe or increase your refund.

If you underpay your estimated taxes, you may owe an underpayment penalty when you file your return. This penalty is essentially interest on the amount you should have paid but didn't, calculated from when the payment was due until you actually paid it. The IRS typically calculates this penalty for you and sends a bill. The penalty applies separately to each payment period based on how much you underpaid and for how long. IRS.gov

The penalty can be waived under certain circumstances. If you retired after age 62 or became disabled during 2015 or 2016, and your underpayment was due to reasonable cause rather than willful neglect, you may qualify for penalty relief. The penalty may also be waived if the underpayment resulted from a casualty, disaster, or other unusual circumstance that would make imposing the penalty unfair.

If you overpay your estimated taxes, you'll receive a refund when you file your 2016 return. Alternatively, you can apply some or all of that overpayment to your 2017 estimated taxes. This decision is made on your 2016 Form 1040, and once you make the choice to apply an overpayment forward, you cannot change your mind and request a refund instead.

Making estimated payments doesn't exempt you from filing your annual return. You still must file Form 1040 by the regular deadline and reconcile your actual income and deductions with what you estimated. Your estimated payments are simply prepayments of your final tax bill.

FAQs

Can I make my estimated tax payments online instead of mailing checks?

Yes, the IRS offers several electronic payment options that are often more convenient than mailing vouchers. You can pay directly from your bank account through IRS Direct Pay at no charge, or use a debit or credit card through authorized service providers (though they charge convenience fees). You can also pay by phone through the Electronic Federal Tax Payment System (EFTPS) after enrolling. Electronic payments let you schedule payments in advance and receive immediate confirmation. IRS.gov

What if I realize my estimated payment is too high or too low after I've already made some payments?

You can adjust your remaining payments for the year at any time. Simply complete a new Estimated Tax Worksheet using your updated income projections, and calculate new payment amounts for the remaining quarters. You don't need to amend vouchers you've already submitted—just change the amounts going forward. If you significantly underestimated, you might still owe a penalty for earlier quarters, but adjusting now prevents the penalty from growing larger. If you overestimated, you'll simply get a larger refund or credit when you file your annual return.

I have both W-2 wages and self-employment income. Do I still need to make estimated payments?

It depends on how much tax is being withheld from your wages compared to your total expected tax liability. You might be able to avoid estimated payments by increasing the withholding on your W-2 income to cover the tax on your self-employment income. File a new Form W-4 with your employer, requesting additional withholding on line 6. This approach is often simpler than making quarterly estimated payments. Use the Tax Withholding Estimator tool on IRS.gov to determine if your current withholding is sufficient or if you need to make estimated payments.

Do estimated tax payments apply only to federal taxes, or do I also need to make state estimated payments?

Form 1040-ES covers only your federal estimated taxes. Most states have separate estimated tax requirements if you have income that isn't subject to withholding. You'll need to check with your state tax agency about their estimated payment rules, deadlines, and forms. State estimated tax requirements often mirror the federal rules but with different payment amounts and sometimes different due dates.

What happens if my spouse and I file jointly but only one of us has self-employment income?

You can make joint estimated tax payments if you're married and plan to file a joint return. Both names and Social Security numbers go on the voucher, and you pay estimated taxes as a couple. However, if either spouse is a nonresident alien, you're separated under a divorce decree, or you have different tax years, you cannot make joint estimated payments. Each person must make separate payments in those situations. If you make joint estimated payments but then decide to file separately, things become complicated—generally, whoever made the payments gets credit for them unless you can prove otherwise.

I'm self-employed and just started my business mid-year. How do I handle estimated taxes?

You only need to make estimated payments for the quarters during which you had income. If you started your business in July, for example, your first payment would be due September 15, covering July and August income. Use the annualized income installment method to calculate payments based on when you actually earned income rather than dividing the year into equal quarters. This prevents penalties for periods before you had any business income. Complete a Form 1040-ES worksheet based on your expected income from your start date through December 31, and divide the result by the number of remaining payments.

Will I owe a penalty if I pay all my estimated tax with my annual return instead of making quarterly payments?

Generally, yes. The IRS requires estimated taxes to be paid throughout the year, not all at once when you file your return. Even if you pay everything you owe by the April filing deadline, you may still face an underpayment penalty for not paying quarterly. The penalty is calculated based on how much you should have paid in each quarter and how long those amounts went unpaid. The only way to avoid this is if you meet one of the exceptions (owing less than $1,000, having no prior year tax liability, or paying at least 90% of current year or 100%/110% of prior year tax).
