How the aggregate method was worked out
| Federal withholding on one regular paycheck · $2,307.69 gross | $193.08 |
| Federal withholding on that paycheck plus the bonus · $7,307.69 treated as one paycheck | $1,320.54 |
| Difference: withheld from the bonus | $1,127.46 |
IRS Publication 15 (2026), section 7: add the bonus to a regular paycheck, work out withholding on the total as if it were one paycheck, and subtract what the regular paycheck alone has withheld. In the aggregate column the South Dakota figure uses the state's regular withholding formula the same way. State payroll programs (disability, paid leave, local taxes) are included in both columns.
