Estimated Tax Payments: Are You Required to Make Them?
In recent months, both the Massachusetts Department of Revenue and the Internal Revenue Service (IRS) have noticeably increased enforcement of estimated tax payment penalties, sending out more notices than usual. Many of my clients have been surprised by these penalties—especially those who typically file their taxes without issue. Because of this uptick in enforcement, I felt it was important to clarify the rules around estimated tax payments and help you understand whether they apply to you.
💡 What Are Estimated Tax Payments?
Estimated tax payments are periodic advance payments of income tax made throughout the year on income that isn’t subject to automatic withholding—such as income from self-employment, side gigs, rental income, interest, dividends, or capital gains.
But even W-2 wage earners can be affected if their employer doesn’t withhold enough based on their actual tax liability. That’s where many people get caught off guard.
⚠️ Who Is Subject to Estimated Tax Penalties?
The IRS generally requires you to make estimated tax payments if both of the following apply:
• You expect to owe at least $1,000 in tax for the current year after subtracting withholding and credits, and
• You expect your withholding and refundable credits to be less than the smaller of:
• 90% of the tax you owe for the current year, or
• 100% of the tax you owed last year (or 110% if your adjusted gross income was over $150,000).
(These are the 2024 figures, and Massachusetts follows a similar guideline for state income taxes.)
So even if you’re a W-2 employee, if your employer isn’t withholding enough tax—and you don’t adjust your withholdings during the year—you could be subject to a penalty for underpayment.
🧾 Common Situations That Trigger Estimated Tax Issues
• You started a side business (Schedule C income)
• You sold stocks, real estate, or crypto with capital gains
• You collected rental income or freelance income
• You or your spouse received a bonus or unexpected income
• You claimed fewer withholdings on your W-4 or didn’t update it after a life change (marriage, divorce, new job)

💼 Estimated Tax Payments for the Self-Employed: What You Need to Know
If you’re self-employed, whether as a sole proprietor, freelancer, gig worker, or independent contractor, you are responsible for paying your own taxes throughout the year—including both income tax and self-employment (SE) tax. This is very different from traditional employees whose taxes are automatically withheld from their paychecks.
Since the IRS requires taxes to be paid as income is earned, you’re expected to make four estimated tax payments per year, usually due:
• April 15
• June 15
• September 15
• January 15 (of the following year)
Failure to make these payments in full and on time can result in underpayment penalties and interest charges, even if you end up paying the full amount by tax season.
📊 How to Calculate Your Quarterly Payments
Your estimated tax payments are based on your expected income, deductions, and credits for the year. You generally have two options:
✅ Safe Harbor Method
To avoid penalties, pay the lesser of:
• 90% of your current-year tax liability, or
• 100% of your prior-year tax liability (or 110% if your AGI was over $150,000)
✅ Annualized Income Method
If your income is seasonal or uneven, we can help you calculate each quarter based on actual income earned so you’re not overpaying early in the year.
🧾 What Income Triggers Estimated Taxes?
Here’s a list of income types that typically require quarterly estimated payments:
• Self-employment (Schedule C income)
• 1099 income (consulting, freelance, gig work)
• Rental income
• Business income through LLCs or partnerships
• Cryptocurrency sales
• Stock sales and capital gains
• Dividend or interest income
