What filing status changes in Delaware
- Delaware does not widen its tax bands for married couples. All 7 stay exactly the same whether you file alone or jointly, so two incomes stack straight into them.
- Head of household gets no special schedule in Delaware — it uses the same bands as a single filer. The federal return may treat you differently, but the state one will not.
- Delaware shelters your first $3,250 from tax when you file alone. Filing together doubles it, to $6,500.
- The Delaware schedule does not double, or otherwise widen, for married-filing-jointly: all 7 thresholds are shared with the single schedule and the top rate remains about 6.6%. Whether this is deliberate policy or legislative inertia varies by state; the effect on a dual-income household is the same either way.
- Delaware applies the single-filer schedule to head-of-household returns rather than publishing a separate table. The status can still matter federally, and can still affect the state's own deduction, but it moves no bracket threshold here. Assuming the federal treatment carries across is a common and costly inference.
- Standard deduction in Delaware: $3,250 single, $6,500 joint. The precise doubling matters more to low earners than to high ones, since a fixed-dollar shelter is a larger share of a smaller income — which is where a shortfall in doubling would bite hardest.

Questions people ask
If I earn more, does the higher rate apply to everything?
No. Each band charges only the money inside it, so income is taxed in slices. That is why the share actually leaving at a typical income is about 4.96% rather than the top rate of about 6.6%.
Is there an amount this state does not tax at all?
Yes. The first $5,250 of a single filer's income is out of reach — the standard deduction plus any opening band charged at nothing. Tax only starts above that line.
Do the brackets change at all when we file together?
They do not move. Delaware uses the same thresholds for both, so a joint return meets each band at the single-filer point.
Does the tax-free allowance double when we file together?
It does. A joint return gets $6,500 against $3,250 for one person — exactly twice, so the allowance itself neither rewards nor penalizes marrying, whatever the brackets above it do.
How do this state's marginal rates apply across income?
Delaware applies each marginal rate only to income within its bracket. The top marginal rate is about 6.6%; measured effective liability at this project's representative income is about 4.96%. Crossing a threshold cannot reduce net income.
Where does state income tax liability begin here?
Liability commences above $5,250 for a single filer, comprising the standard deduction and any zero-rate opening bracket. Filers below that threshold owe no state income tax, though a return may still be required.
Why are joint and single thresholds identical here?
Delaware applies identical bracket thresholds to single and joint filers. Combined income therefore reaches each marginal rate at the single-filer threshold, which is the strongest form of marriage penalty a graduated schedule can produce.
How does the standard deduction scale for joint filers here?
The standard deduction doubles exactly for joint filers — $3,250 to $6,500 — so the deduction component is marriage-neutral. Bracket thresholds scale independently and may not be.
