On $40,000 with $4,800 withheld, you would get back $2,824. Your total federal tax is $2,620 — the refund is just the difference.
A refund is not a bonus and it is not based on your salary. It is the gap between what you actually owed and what your employer already sent to the IRS on your behalf. On $40,000 as a single filer taking the standard deduction, the federal tax owed is $2,620. If $4,800 was withheld across the year, the result is a refund of $2,824 — the money was always yours, it just went early.
That is why the same salary produces wildly different refunds for different people. Change the number on your W-4 and the refund changes without your tax bill moving a cent. The table below runs $40,000 across the withholding levels people actually have, and the calculator underneath lets you put in the real figure from your last payslip along with credits, dependants and your state.
