Standard Deduction

What is Standard Deduction?

The standard deduction is a specific dollar amount set by the IRS each year that taxpayers can subtract from their adjusted gross income before calculating the tax they owe. It is available to most filers and eliminates the need to itemise individual deductions such as mortgage interest, charitable contributions, or medical expenses.

Why Standard Deduction Matters

The standard deduction amount varies based on filing status, age, and whether the taxpayer is blind. For many employees, choosing the standard deduction simplifies tax filing and results in a lower tax burden compared to itemising, especially after the increases introduced by the Tax Cuts and Jobs Act of 2017.

Payroll and HR professionals should understand how the standard deduction affects employee tax withholding and be prepared to guide employees during W-4 completion, even though the deduction itself is claimed when filing an annual return.
