Today marks the federal income tax filing deadline for 2025 returns, and taxpayers are navigating several notable changes to deduction and credit rules. The standard deduction has increased to $15,000 for single filers and $30,000 for married couples filing jointly.

The expanded child tax credit, which provides up to $2,500 per qualifying child, has proven popular but also introduced complexity for families with shared custody arrangements. Tax preparers report an increase in amended return filings related to credit allocation disputes.

The IRS reminds taxpayers that filing an extension grants additional time to submit returns but does not extend the deadline for payment. Estimated tax penalties apply to underpayments regardless of extension status.
