Keep in mind

This is a simplified federal estimate using 2025 tax brackets and standard deductions ($15,000 single, $30,000 married filing jointly). It ignores state tax, payroll tax, credits, itemized deductions, and other adjustments — and it isn't tax advice. For decisions, check current IRS figures or a tax professional.
