Paid on a 1099 with no withholding: how quarterly estimated taxes actually work

Yes, in most cases, and here is the rule

If you are self-employed or paid on a 1099 and nobody withholds tax from your income, you generally need to make quarterly estimated tax payments. According to the IRS, individuals, including sole proprietors, partners and S corporation shareholders, generally must pay estimated tax if they expect to owe $1,000 or more when they file. The payments cover both income tax and self-employment tax, and they are due four times a year rather than all at once in April.

We at Hockaday CPA work with a lot of people who are paid this way: real estate agents, insurance brokers, sales professionals, landscapers, consultants and owners of family businesses. The first year on a 1099 is often the year someone discovers estimated taxes, usually through a large balance due and a penalty. This guide explains how the system works, how to size the payments, and the habits that keep April from being a shock. It is general information; a licensed CPA can calculate the right amounts for your situation.

Why the IRS wants its money during the year

The federal tax system is pay as you go. For employees, the employer withholds tax from each paycheck and sends it in, so by April most of the year's tax has already been paid. When you work for yourself, no one does that for you, so the IRS expects you to send payments as you earn. Estimated payments are simply your version of withholding.

Two pieces surprise new self-employed people. The first is self-employment tax, which covers Social Security and Medicare. An employee splits those taxes with the employer; when you are self-employed, you pay both halves yourself. The second is that the obligation exists even if you end up owing nothing extra in April. The IRS notes that a penalty for underpaying during the year can apply even if you are due a refund when you file, because the question is whether you paid on time, not only whether you paid enough in total.

The four due dates, and why they are uneven

The IRS divides the year into four payment periods, and they are not equal quarters. According to the IRS, the payment for income earned January 1 through March 31 is due April 15; April 1 through May 31 is due June 15; June 1 through August 31 is due September 15; and September 1 through December 31 is due January 15 of the following year. If a due date falls on a weekend or legal holiday, the payment is on time if made on the next business day.

The uneven periods catch people out. The second payment comes only two months after the first, and the fourth payment is due after the year has ended, right when holiday spending is on everyone's mind. Put all four dates on your calendar now, with a reminder a week ahead of each.

• January 1 to March 31: due April 15
• April 1 to May 31: due June 15
• June 1 to August 31: due September 15
• September 1 to December 31: due January 15 of the next year

The safe harbors that keep you out of penalty

You do not have to predict your income perfectly. The IRS provides safe harbor rules, and meeting one of them generally means no underpayment penalty even if you owe more when you file. According to the IRS, most taxpayers avoid the penalty if they owe less than $1,000 after subtracting withholding and credits, or if they paid at least 90 percent of the current year's tax, or 100 percent of the prior year's tax, whichever is smaller.

There is an important adjustment for higher earners. The IRS states that if your adjusted gross income for the prior year was more than $150,000, or $75,000 if married filing separately, the prior-year test becomes 110 percent of last year's tax rather than 100 percent. For a household whose income is rising quickly, paying based on last year's tax under the right percentage is often the simplest way to stay safe, with the balance settled in April.

Sizing your payments without guessing

There are two common ways to decide what to pay. The first is the prior-year method: take last year's total tax, apply the 100 or 110 percent rule, and divide by four. It is simple, predictable and protects you from the penalty, but it can leave a large balance due if this year is much better than last. The second is the current-year method: estimate this year's profit as you go and pay enough to cover roughly 90 percent of this year's tax. It tracks reality more closely, but it only works if your books are current.

In practice, I usually recommend starting with the prior-year method for safety and then checking actual profit midyear. If the business is well ahead of last year, raising the third and fourth payments avoids an April surprise. If income has dropped, you may be able to reduce later payments. Either way, the calculation depends on knowing your profit, which is one more reason to keep the books current all year. Our guide on which records to keep and for how long explains what supports those numbers.

Behind on payments this year?

If you have skipped a payment or two, the best time to catch up is now. Paying sooner reduces the underpayment penalty, which is calculated based on how long the shortfall lasts. Bring us your year-to-date numbers and last year's return, and we can calculate what to pay for the remaining periods and whether you can still meet a safe harbor. The first consultation is free.

How to actually send the money

According to the IRS, you can mail payments with Form 1040-ES vouchers, pay online, by phone or through the IRS app, or pay through your IRS online account. Businesses can use their business tax account or Direct Pay, and some payments must go through the Electronic Federal Tax Payment System. Whichever method you choose, keep the confirmation for every payment with its date and amount, because your preparer will need the total when the return is filed.

Texas has no state income tax, so for most people here there is no separate state estimated payment to make. If you earn income in another state, or you moved to Texas partway through the year, the other state may expect its own estimated payments; our guide on what changes when you move to Texas covers that situation.

If you also have a paycheck

Many people have a salaried job and a side business, or a spouse with a W-2. In that case there may be an easier route. The IRS notes that salaried workers can avoid estimated payments by asking their employer to withhold more tax, by filing a new Form W-4 and entering an extra amount on the special line. For a two-income household, that one form can replace four separate payments and the calendar reminders that go with them.

The IRS also offers a Tax Withholding Estimator to check whether enough is being withheld. For a household with both wage and self-employment income, adjusting withholding is often less work than tracking four separate payments, though a CPA can help you decide which approach is cleaner for your family.

The mistakes behind most penalties, and the habits that prevent them

The most common mistake is not knowing the payments exist until the first 1099 year is over. The second is paying the wrong amount because the books are months behind. The third is forgetting self-employment tax and planning only for income tax. The fourth is treating January's payment as optional because it lands after year end. Each of these leads to the same outcome: a balance due plus a penalty.

The IRS may waive the underpayment penalty in limited cases, such as when it resulted from a casualty, disaster or other unusual circumstance, or for certain people who retired after age 62 or became disabled and had reasonable cause. Form 2210 is used to figure whether a penalty applies. For most people, though, the better strategy is prevention. If you are close to the deadline and unsure whether you will have the full amount, our guide on extensions and filing on time explains what an extension does and does not change.

The people who never struggle with estimated taxes are not the ones with the highest incomes. They are the ones who treat tax as money that was never theirs to spend.

• Open a separate savings account for taxes and move a set percentage of every deposit into it
• Keep your books current monthly so you know your actual profit before each due date
• Calendar all four due dates with a reminder a week ahead
• Save every payment confirmation with its date and amount
• Revisit the amount midyear if income has risen or fallen sharply
• Talk to your CPA before the fourth payment, when there is still time to plan for the year
