If you have self-employment or other income outside of your W-2 paycheck this year, you may need to send the IRS some money before the usual tax-filing time. Here are the due dates for paying quarterly estimated taxes in 2016; they are supposed to be in four equal installments. This is for federal taxes only, state and local tax due dates may be different.
IRS Estimated Tax Payment Calendar for Individuals
| Tax Year / Quarter | Due Date |
| 2016 First Quarter | April 18, 2016 (Monday) |
| 2016 Second Quarter | June 15, 2016 (Wednesday) |
| 2016 Third Quarter | September 15, 2016 (Thursday) |
| 2016 Fourth Quarter | January 17, 2017* (Tuesday) |
* You do not have to make the Q4 payment due January 17, 2017, if you file your 2016 tax return by January 31, 2017 and pay the entire balance due with your return.
Who needs to pay estimated taxes?
In general, you must pay estimated tax for 2016 if both of the following apply:
- You expect to owe at least $1,000 in tax for 2016, after subtracting your withholding and refundable credits.
- You expect your withholding and credits to be less than the smaller of
- 90% of the tax to be shown on your 2016 tax return, or
- 100% of the tax shown on your 2015 tax return. Your 2015 tax return must cover all 12 months.
If you forget to pay (like I’ve done before), then you should make a payment as soon as possible even though it is late. This will minimize any penalty assessed.
How do I pay? When does the payment count?
- By check. Fill out the appropriate IRS Form 1040-ES voucher (last page of the PDF) and snail mail to the indicated address. The date of the U.S. postmark is considered the date of payment. No fees besides postage.
- By online bank transfer. You can store your bank account information and pay via electronic funds transfer at EFTPS.gov or call 1-800-555-4477. It takes a little while to set up an online account initially, so you’ll need to plan ahead. For a quick one-time payment, you can also use IRS Direct Pay (just introduced in 2014) which does not require a sign-up but it also doesn’t store your bank account information for future payments. Both are free, there are no convenience fees. The date of payment will be noted online.
- By debit or credit card. Here is page of IRS-approved payment processors. Pay by phone or online. Fees will apply, but the payment will count as paid as soon as you charge the card. You may also earn rewards on your credit card. Check if there is a discounted fee available via limited-time promotion.
How much should you pay in estimated taxes? You’ll need to come up with an expected gross income and then estimate your taxes, deductions, and credits for the year. The PDF of Form 1040-ES includes a paper worksheet to calculate how much in quarterly estimated taxes you should pay. You can also try online tax calculators like this one from H&R Block to estimate your 2016 tax liability, and divide by four quarters.
Did you as a small business pay another person or unincorporated business more than $600 total in the last year? You may have to provide them a 1099-MISC form.
What is success? Perhaps you think of a new idea, get some venture capital, grow and scale like crazy, and then you sell it after a few years for mega-millions. More traditionally, you work your way up the corporate ranks, become a manager/executive, and make good money that way. Or perhaps you start a small business and expand it over decades. All are good and fine.
While procrastinating today, I of course ran across a couple of tips on productivity and success that both powerful and very different.
