📉 What Is the Underpayment Penalty?

The IRS runs on a pay-as-you-go system. If you earn income without withholding—like from freelancing, self-employment, or investments—you’re required to pay estimated taxes throughout the year. If you underpay and owe more than $1,000 when you file, the IRS may charge an underpayment penalty, calculated quarterly using Form 2210. It applies even if you pay the full tax by April. What matters is when during the year you paid it.

âś… Ways to Avoid the Penalty

  • Follow Safe Harbor Rules:
    • Pay 90% of your current year’s tax, OR
    • Pay 100% of last year’s tax (or 110% if you earned over $150,000)
  • Pay On Time: Estimated taxes are due quarterly:
    • April 15
    • June 15
    • September 15
    • January 15 (of the following year)
  • Increase Withholding: If you’re employed and earn side income, increasing paycheck withholding can help avoid quarterly penalties.

🧾 Track and Prove Payments with Zoho Expense

The best way to protect yourself from penalties—and defend against IRS audits—is to track estimated payments clearly in Zoho Expense:
  • Log each IRS payment as a separate expense (e.g., “IRS Q2 Payment”)
  • Upload proof of payment—bank receipts, check copies, or IRS confirmations
  • Use tags or notes to label quarters and tax year
  • Create custom reports to verify safe harbor thresholds
  • Store Form 2210 in your Zoho WorkDrive folder
💡 Tip: This gives you a clean, timestamped audit trail—exactly what the IRS wants if you’re ever questioned.

đźš« What If You Already Owe a Penalty?

You may still qualify for penalty relief:
  1. Reasonable Cause Relief: Illness, natural disasters, or other hardships can excuse late payments
  2. First-Time Abatement: If you filed on time for the last three years, the IRS may waive your penalty once
Keep detailed documentation in Zoho WorkDrive if you plan to request abatement.
