How we compute your Delaware take-home

1. Start with your annual gross wage income.
2. Subtract pre-tax deductions (401(k), HSA, pre-tax insurance premiums).
3. Apply federal income tax using the 2026 projected IRS brackets + standard deduction.
4. Apply FICA: 6.2% Social Security up to $184,500 wage base, 1.45% Medicare on all wages plus 0.9% additional Medicare above the filing-status threshold.
5. Apply Delaware state tax per the rules above.
6. Divide by your pay frequency (weekly / bi-weekly / semi-monthly / monthly) for per-paycheck take-home.

For estimation only — state tax has nuances (local city taxes, tax credits, itemized deductions) we don't model. Always confirm with a CPA or your state's revenue department for filing.
