Self-Employed Quarterly Tax Payments: What CEOs Must Know

Self-Employed Quarterly Tax Payments: What CEOs Must Know
Updated October 20, 2026

If you are self-employed the tax year does not end in April. Freelancers, small business owners and gig workers pay estimated tax every three months, and a missed payment draws a penalty that runs from its own due date rather than from the filing deadline.

‍

Missing estimated payments is one of the most common and most expensive mistakes self-employed people make, because the IRS charges a penalty on every quarter you come up short, figured separately for each due date (Instructions for Form 2210). But with the right strategy, you can stay compliant, maximize deductions, and avoid financial stress. Here’s what you need to know.

Why CEOs & Business Owners Should Pay Attention to Self-Employed Quarterly Tax Payments

If you’re a CEO, founder, or business leader, your own return is only part of the exposure. Your employees and contractors also rely on you to ensure compliance and avoid financial missteps. Mismanaging estimated tax payments can lead to:

  • Employee misclassification penalties (if workers are incorrectly labeled as independent contractors)
  • IRS audits for non-compliance
  • Cash flow disruptions due to unexpected tax liabilities
  • Increased tax burden if estimated payments are miscalculated

CEOs should implement tax planning strategies to ensure both their own and their company’s financial health. Our tax planning work covers payroll taxes, deductions and the compliance side together, because a change in one moves the others.

Who Needs to Make Self-Employed Quarterly Tax Payments?

If you’re self-employed and expect to owe at least $1,000 in taxes after deductions and credits, the IRS requires you to make estimated tax payments. This includes:

  • Freelancers & Contractors (writers, designers, consultants, etc.)
  • Small Business Owners & LLCs
  • Gig Workers (Uber, DoorDash, Airbnb hosts, etc.)
  • Side Hustlers & Content Creators (Etsy sellers, influencers, YouTubers)
  • CEOs & Business Owners Paying Themselves (via draws or distributions)

Key Deadlines for 2026 Self-Employed Quarterly Tax Payments

Mark these IRS due dates in your calendar to stay ahead:

  • April 15, 2026: Covers income earned Jan 1–Mar 31
  • June 15, 2026: Covers income earned Apr 1–May 31
  • Sept 15, 2026: Covers income earned Jun 1–Aug 31
  • Jan 15, 2027: Covers income earned Sept 1–Dec 31

If you overpay, you’ll get a refund. Underpay? You could owe penalties, even if you settle by April 15.

How to Calculate Your Self-Employed Quarterly Taxes

Your estimated tax payments include:

  • Income Tax: Based on your total earnings and tax bracket
  • Self-Employment Tax (15.3%): Social Security at 12.4% on net earnings up to $184,500 for 2026, then Medicare at 2.9% with no ceiling (IRS Topic 751). Past the cap the marginal rate falls from 15.3% to 2.9%, which is the part that matters on a founder’s own draws. Above $200,000 of earnings for a single filer, the 0.9% Additional Medicare Tax takes it to 3.8% (IRS Topic 560).

You can deduct half of this on your tax return, and the example below does.

Example calculation for $80,000 of net freelance earnings in 2026:

  • Self-employment tax: only 92.35% of net earnings is subject to it (Schedule SE, line 4a), so $80,000 × 0.9235 = $73,880, and $73,880 × 15.3% = $11,304.
  • Half of that is deductible: $5,652 comes off adjusted gross income, leaving $74,348.
  • Income tax: the rates are graduated, not one flat bracket. After the 2026 standard deduction of $16,100 (Rev. Proc. 2025-32) and an $11,650 QBI deduction, taxable income is $46,598 and the tax is $5,344. The top bracket actually reached is 12%, not 22%.
  • Total: $16,648, or about $4,162 per quarter.

Those figures assume a single filer with no other income and no state tax. The shape matters more than the total: apply 15.3% to gross and skip the deductions and you will overpay by thousands.

Self-employment tax, step by step2026Net earnings from self-employment$80,000× 92.35%, Schedule SE line 4aAmount subject to the tax$73,880× 15.3%Self-employment tax$11,304half comes back as a deductionDeducted from adjusted gross income$5,652The two halves stop at different places12.4% Social Security ends at $184,500 of earnings.The 2.9% Medicare part never does.
Figure 1The 92.35% step is the one everybody drops. Applying 15.3% straight to gross earnings overstates the tax by about 8%, and forgetting that half of it is deductible overstates the income tax on top of that. Both mistakes push the quarterly payment up, so the money sits with the IRS until you file.

Deadlines vary by state and business situation. Use IRS Form 1040-ES or trusted tax software for accuracy. Our tax solutions page covers the filing side.

Avoid These Costly Mistakes

  • Skipping Payments: The IRS charges penalties if you don’t pay at least 90% of this year’s tax or 100% of last year’s tax, whichever is smaller, rising to 110% if last year’s adjusted gross income was above $150,000 (Form 1040-ES, 2026).
  • Underestimating Your Income: If you land a big project, adjust your payments so you don’t owe a lump sum in April.
  • Ignoring Deductions: Every missed deduction means you overpay, and the fix is record-keeping rather than a better calculator. Keep receipts for:
    • Home office expenses
    • Internet & software costs
    • Mileage & travel
    • Business meals & Education

Why CEOs & Business Owners Need Tax Experts

  • Get the entity election right: above a certain profit level an S corporation election splits earnings between a reasonable salary and distributions, and only the salary carries the 15.3%.
  • Reduce IRS audit risk with accurate filings.
  • Maximize deductions and keep more of your hard-earned income.
  • Ensure tax compliance for employees & independent contractors to avoid legal trouble.

Frequently asked

Questions, answered

How do I calculate my quarterly estimated tax payment if my income varies?

Estimate your full-year net income, total tax (income plus self-employment tax), then divide by four. If income is uneven, use the annualized income installment method on Form 2210 so you pay more in high-earning quarters and less in slow ones, instead of equal installments. Recalculate after any large invoice, sale, or expense shift. Many self-employed people simply set aside 25-30% of each payment received into a separate account to fund the estimates.

What is the safe harbor rule for avoiding underpayment penalties?

You generally avoid the penalty if your withholding plus estimated payments equal at least 90% of this year's tax or 100% of last year's tax, whichever is smaller. If your prior-year adjusted gross income exceeded $150,000, the prior-year threshold rises to 110%. Paying based on last year's known number is the safer play when this year's income is hard to predict, since it locks in protection regardless of how much you ultimately earn.

How much is self-employment tax and can I reduce it?

Self-employment tax is 15.3%: 12.4% Social Security on earnings up to the annual wage base ($184,500 in 2026) plus 2.9% Medicare on all net earnings, with no cap. You deduct the employer-equivalent half when figuring adjusted gross income. The main lever to reduce it is electing S-corp status, which lets you split income between a reasonable salary (subject to the tax) and distributions (not subject to it). This only makes sense above a certain profit level.
