According to the IRS, nearly 20% of small businesses fail to meet their quarterly tax deadline, incurring fines and interest charges (IRS, 2024). To maintain financial health and avoid unnecessary tax burdens, businesses must stay ahead of their estimated tax payments.

What Are Quarterly Tax Payments, and Why Do They Matter?

Quarterly tax payments are required for businesses and self-employed individuals who anticipate owing at least $1,000 in taxes annually after withholding and credits. The IRS mandates these payments to prevent year-end tax surprises and ensure the government collects revenue evenly throughout the year.For businesses like campgrounds, marinas, and short-term rental operations, fluctuating income can make quarterly tax calculations challenging. Without proper planning, companies might underpay their taxes, leading to penalties.

Meeting the quarterly tax deadline ensures businesses avoid costly penalties. The next payment dates are:

• April 15, 2025 – Q1 Payment Due
• June 15, 2025 – Q2 Payment Due

Common Mistakes When Filing

1. Misclassifying Business Expenses

Failing to correctly categorize deductible expenses can lead to lost tax benefits. For instance, multifamily property owners may overlook depreciation deductions, while SaaS companies might miscategorize research and development costs. Keeping detailed records and consulting a tax professional can prevent these errors.

2. Underpaying Estimated Taxes

Industries with seasonal revenue cycles—such as RV parks and self-storage businesses—often struggle with estimating their quarterly tax obligations. The IRS imposes penalties for underpayments, even if businesses pay the full amount by the end of the year. Using IRS Form 1040-ES or 1120-W helps determine the correct payment amounts (Investopedia, 2024).

3. Missing the Quarterly Tax Deadline

The IRS sets quarterly tax deadlines on April 15, June 15, September 15, and January 15. Late payments result in interest and penalties that accumulate over time.

4. Failing to Track Tax Law Changes

New IRS regulations, including digital asset reporting and updates for cryptocurrency investors, impact how transactions must be reported (IRS, 2025). Many businesses investing in crypto unknowingly underreport taxable income, leading to compliance issues.

5. Combining Personal and Business Finances

Mixing personal and business finances creates confusion and can trigger IRS audits. Businesses, including private equity funds and short-term rental owners, should maintain separate accounts to track income and expenses properly.
