Frequently Asked Questions
The 2026 calculator estimates your refund for the 2025 tax year — the income you earned from January 1 through December 31, 2025. You file this return in 2026, which is why it is called the 2026 calculator. The tax brackets and deductions used are the confirmed 2025 values.
The standard deduction for the 2025 tax year is $15,000 for single filers, $30,000 for married filing jointly, $15,000 for married filing separately, and $22,500 for head of household. These amounts reflect the One Big Beautiful Bill Act framework with inflation adjustments.
The federal filing deadline for 2025 tax returns is April 15, 2026. You can request an automatic six-month extension by filing Form 4868, which moves the deadline to October 15, 2026. However, any tax owed must still be paid by April 15 to avoid penalties and interest.
The 2026 calculator is pre-configured for the 2025 tax year with confirmed IRS brackets and deductions. The main calculator allows you to toggle between tax years. Both use identical calculation logic — the difference is just the default year setting and the content focused on current-year filing.
The 2025 brackets reflect inflation adjustments to the One Big Beautiful Bill Act framework. The standard deduction increased from approximately $14,600 (2024) to $15,000 (2025) for single filers.
