What is the standard deduction for a single filer for the 2025 tax year?

For tax year 2025, the standard deduction for single filers is $15,000, up from $14,600 in 2024 due to inflation adjustments. Married couples filing jointly receive a $30,000 standard deduction, and heads of household receive $22,500. The standard deduction reduces your taxable income dollar for dollar, and the vast majority of Americans — approximately 90% — claim the standard deduction rather than itemizing because it is simpler and often more beneficial.
