Quarterly pay is any money paid or owed four times a year, once per calendar quarter. In everyday use it covers three very different things: performance bonuses and sales commissions that employers hand out every three months, stock dividends that companies distribute to shareholders, and the estimated federal income tax payments that self-employed workers and others without paycheck withholding send to the IRS. Each type runs on its own schedule and its own rules.
The Four Quarters
The calendar year breaks into four three-month blocks:
- Q1: January 1 through March 31
- Q2: April 1 through June 30
- Q3: July 1 through September 30
- Q4: October 1 through December 31
Each quarter runs about 13 weeks, which is why businesses use it as a natural unit for sales targets, financial reporting, and pay cycles.1Internal Revenue Service. Publication 509 (2026), Tax Calendars Some companies use a fiscal year that starts in a month other than January, but they still divide their year into four three-month segments for reporting and compensation.
The Common Forms of Quarterly Pay
Bonuses and Sales Commissions
Many employers tie bonuses to quarterly targets — revenue goals, client retention, production quotas, or other benchmarks written into an employment contract. Sales commissions often follow the same schedule because deals take weeks or months to close and verify. For tax purposes, both count as supplemental wages, which changes how they are withheld (covered further down).
Stock Dividends
Shareholders in publicly traded companies may receive dividends, a portion of company profits, on a quarterly schedule. A company’s board of directors decides whether to pay a dividend and how much per share. Not every company pays dividends, and those that do can cut or eliminate them at any time.
Qualified dividends are taxed at lower federal rates than ordinary income: 0%, 15%, or 20%, depending on your taxable income and filing status. Any entity that pays you $10 or more in dividends during the year must send you a Form 1099-DIV by January 31 of the following year.2Internal Revenue Service. Publication 1099 General Instructions for Certain Information Returns – 2026
Estimated Tax Payments
If you earn income the IRS doesn’t see through paycheck withholding — freelance work, self-employment, rental income, investment gains, dividends — you generally have to pay federal income tax in four installments through the year rather than as a single check next April. This is the most rule-heavy form of quarterly pay, so it gets its own sections below.
Who Has to Pay Estimated Tax
You generally owe quarterly estimated tax if you expect your federal tax bill for the year to run $1,000 or more after subtracting withholding and refundable credits.3Internal Revenue Service. Form 1040-ES – 2026 That sweeps in sole proprietors, freelancers, partners, S corporation shareholders, and anyone with meaningful income from interest, dividends, capital gains, alimony, or prizes.4Internal Revenue Service. Estimated Taxes
There is a second condition. You must also expect your withholding and refundable credits to fall below the smaller of 90% of your current-year tax or 100% of the tax on your prior-year return. If your prior-year adjusted gross income exceeded $150,000 ($75,000 if married filing separately), that 100% figure rises to 110%.5Internal Revenue Service. Estimated Tax – FAQs
You work out each installment on Form 1040-ES, which walks through projecting annual income, deductions, and credits, then splitting the result into four payments. The form includes the year’s tax rate schedules by filing status.3Internal Revenue Service. Form 1040-ES – 2026
Estimated Tax Deadlines
The IRS splits the year into four payment periods, and they are not evenly spaced. The periods and the deadlines that go with them:
- Period 1 (January 1 – March 31): payment due April 15
- Period 2 (April 1 – May 31): payment due June 15
- Period 3 (June 1 – August 31): payment due September 15
- Period 4 (September 1 – December 31): payment due January 15 of the following year
The second period covers only two months, the fourth covers four. Most people ignore the unevenness and pay equal quarterly amounts. When a deadline falls on a Saturday, Sunday, or federal holiday, it shifts to the next business day.5Internal Revenue Service. Estimated Tax – FAQs
You control the timing of your payments. The IRS accepts them electronically through IRS Direct Pay or the Electronic Federal Tax Payment System (EFTPS), and they are credited on the date you submit.
Avoiding the Underpayment Penalty
If you underpay or miss an installment, the IRS charges a penalty based on the shortfall for that period, multiplied by the federal underpayment interest rate for the time the shortfall lasted.6Office of the Law Revision Counsel. 26 USC 6654 – Failure by Individual to Pay Estimated Income Tax You can avoid the penalty entirely by hitting one of three safe harbors:
- Total payments equal at least 90% of the tax you owe for the current year.
- Total payments equal at least 100% of the tax on your prior-year return (which must have covered a full 12 months).
- If your prior-year adjusted gross income exceeded $150,000 ($75,000 if married filing separately), total payments equal at least 110% of that prior-year tax.7Office of the Law Revision Counsel. 26 USC 6654 – Failure by Individual to Pay Estimated Income Tax
Meeting any one of these protects you, even if your actual bill turns out higher than you paid in.5Internal Revenue Service. Estimated Tax – FAQs
If your income arrives unevenly through the year — a seasonal business, say, or a large investment sale in December — you can lower earlier installments using the annualized income installment method, which sizes each payment to what you actually earned in that period. You report it on Schedule AI of Form 2210.8Internal Revenue Service. Instructions for Form 2210 – Underpayment of Estimated Tax by Individuals, Estates, and Trusts
The IRS may waive all or part of the penalty if you retired after reaching age 62 or became disabled during the current or prior tax year and the underpayment was due to reasonable cause. It may also waive the penalty when a casualty, disaster, or other unusual circumstance made the underpayment happen and charging the penalty would be unfair.9Internal Revenue Service. Instructions for Form 2210 – Underpayment of Estimated Tax by Individuals, Estates, and Trusts
How Bonuses Are Withheld and Overtime Recalculated
Federal Withholding on Bonuses
A quarterly bonus counts as supplemental wages. If your total supplemental wages for the year stay at or below $1 million, your employer can withhold a flat 22% for federal income tax. Anything above $1 million is withheld at 37%.10Internal Revenue Service. Publication 15 (Circular E), Employer’s Tax Guide Those rates only cover federal income tax. Social Security and Medicare taxes still come out on top.
Overtime and Nondiscretionary Bonuses
If your quarterly bonus is nondiscretionary — meaning it is based on preset criteria like a sales target or production quota rather than an unexpected reward decided after the fact — federal law requires your employer to fold it into your regular rate of pay when calculating overtime.11Office of the Law Revision Counsel. 29 USC 207 – Maximum Hours A bonus is discretionary only when both the decision to pay and the amount rest solely with the employer at or near the end of the period, with no prior agreement or promise.
Practically, that means your employer has to go back through every week in the quarter when you worked more than 40 hours, add the bonus into your total pay for those weeks, calculate a new hourly rate, and pay you an extra half-time premium on each overtime hour at the adjusted rate.12U.S. Department of Labor. Fact Sheet 56C: Bonuses Under the Fair Labor Standards Act (FLSA) If your employer skips that recalculation, you may be owed back wages.
When the Money Actually Shows Up
Waiting on a quarterly bonus or commission? Don’t expect it on the last day of the quarter. Employers usually need time after a quarter closes to verify sales figures, reconcile records, and finalize performance reviews. Payouts commonly land two to four weeks into the following month.
Dividends run on a similar lag. After a company’s board declares a dividend, it sets a record date (you have to own the stock by then to qualify) and a payment date, which typically sits a few weeks out. Part of the gap between quarter-end and the check reflects the time companies need to finalize the earnings figures they report to the Securities and Exchange Commission on Form 10-Q, due 40 or 45 days after the quarter ends depending on company size.13U.S. Securities and Exchange Commission. Form 10-Q General Instructions
Estimated tax is the one payment you set the timing on yourself. Send it by the deadline for each period, meet one of the safe harbors, and there is no penalty to worry about.
