Alimony is not taxable in Delaware for divorces finalized after December 31, 2018. Under the Tax Cuts and Jobs Act of 2017, spousal support payments are neither deductible by the paying spouse nor counted as taxable income for the receiving spouse. Delaware fully conforms to federal tax treatment, meaning this rule applies to both your federal return and Delaware state income tax. For the approximately 4,500 Delaware divorces finalized annually since 2019, the tax-neutral treatment simplifies financial planning but eliminates the strategic deduction that higher-earning spouses previously used to reduce their tax burden.

How the Tax Cuts and Jobs Act Changed Delaware Alimony Taxation
The Tax Cuts and Jobs Act of 2017 permanently eliminated the federal alimony tax deduction for divorce agreements executed after December 31, 2018. Under the previous tax regime, the paying spouse could deduct alimony payments from taxable income, while the receiving spouse reported those payments as income. This arrangement typically benefited couples because the higher-earning payer saved more in tax deductions than the lower-earning recipient paid in additional taxes. Congress eliminated this benefit as part of broader tax reform, shifting approximately $6.9 billion in tax liability from recipients to payers over a 10-year period according to Congressional Budget Office estimates.
Delaware conforms to federal income tax treatment for alimony under 13 Del.C. § 1512. The state uses federal adjusted gross income as the starting point for calculating Delaware taxable income, which means the federal alimony rules flow through directly to state taxes. Delaware Family Court judges consider these tax implications when determining alimony awards, potentially adjusting payment amounts to account for the payer's inability to deduct support payments.
The critical date determining which tax rules apply is December 31, 2018. Divorces finalized by this date follow the old rules permanently, meaning the payer continues to deduct alimony and the recipient reports it as income. Divorces finalized January 1, 2019 or later follow the new rules permanently, with no deduction and no taxable income. This distinction remains relevant in 2026 because many long-term alimony orders from pre-2019 divorces continue to be paid under the old tax treatment.
Delaware Alimony Laws Under 13 Del.C. § 1512
Delaware courts award alimony based on judicial discretion rather than a fixed formula, considering at least 13 statutory factors under 13 Del.C. § 1512. The dependent spouse must prove three elements: (1) dependence on the other spouse for support, (2) insufficient property to meet reasonable needs, and (3) inability to support themselves through employment or responsibility as custodian of a child whose condition makes employment inappropriate. Judges weigh factors including the standard of living during marriage, each spouse's earning capacity, contributions to the other's education or career, and the time needed to acquire job skills. Notably, Delaware statute 13 Del.C. § 1512(c) explicitly prohibits consideration of marital misconduct when awarding alimony.
Delaware caps alimony duration at 50% of the marriage length for marriages under 20 years. A 10-year marriage, for example, limits alimony eligibility to a maximum of 5 years. Marriages lasting 20 years or longer have no statutory time limit, allowing courts to award permanent alimony when circumstances warrant. The three types of alimony available in Delaware are interim (temporary support during divorce proceedings), rehabilitative (funding education or job training), and permanent alimony for long-term marriages where self-sufficiency is unlikely.
Tax Treatment by Divorce Date: A Comparison
| Divorce Finalized | Payer Tax Treatment | Recipient Tax Treatment | IRS Form Required |
|---|---|---|---|
| Before Jan 1, 2019 | Deductible from gross income | Taxable as ordinary income | Schedule 1 (Form 1040) |
| After Dec 31, 2018 | Not deductible | Not taxable | None required |
| Pre-2019 modified to new rules | Not deductible | Not taxable | None required |
For divorces finalized before 2019, the paying spouse deducts alimony on Schedule 1 of Form 1040 and must include the recipient's Social Security number. Failure to include the SSN results in disallowance of the deduction plus a $50 IRS penalty. The recipient reports the same amount as income on their Form 1040. For post-2018 divorces, neither party reports alimony payments to the IRS because the payments have no tax consequence for either spouse.
How Courts Calculate Delaware Alimony Awards
Delaware Family Court judges exercise substantial discretion in setting alimony amounts, but they must consider all 13 statutory factors listed in 13 Del.C. § 1512. The court examines the financial resources available to the requesting spouse, including marital property awards. Judges evaluate the time and expense needed for education or training to become employable at an appropriate level. The standard of living established during the marriage serves as a benchmark, though courts do not guarantee that both spouses will maintain it post-divorce.
Courts also consider any financial contributions one spouse made to the other's education or career development. A spouse who supported a partner through medical school or law school, for example, may receive credit for that investment. The paying spouse's ability to meet their own needs while paying alimony is another factor, ensuring orders do not impoverish the payer. Delaware courts may consider any other factor deemed just and appropriate, giving judges flexibility to address unique circumstances.
Alimony modification requires a real and substantial change of circumstances under 13 Del.C. § 1519. Job loss, significant income changes, or serious illness may justify modification. The party requesting modification bears the burden of proving changed circumstances. Alimony terminates automatically upon the death of either party, remarriage of the recipient, or cohabitation of the recipient with another adult in a relationship where they hold themselves out as a couple.
Filing for Divorce in Delaware: Requirements and Costs
Delaware requires at least one spouse to have resided in the state continuously for 6 months before filing under 13 Del.C. § 1504(a). Military members stationed in Delaware satisfy this requirement even if domiciled elsewhere. There is no separate county residency requirement. The petition must be filed in the county where either the petitioner or respondent resides. Delaware has three counties (New Castle, Kent, and Sussex), each with a Family Court location.
The total filing fee is $175, consisting of a $165 petition fee plus a $10 mandatory court security fee as of March 2026. Each additional issue requested (property division, alimony, child custody) adds $50 to filing costs. Service of process costs $10 to $100 depending on the method. Couples with minor children must complete mandatory parent education courses costing $100 to $200. An uncontested divorce in Delaware costs $300 to $2,000 total, while contested divorces average $10,000 to $20,000 and can exceed $50,000 for complex cases involving custody disputes or business valuations.
Delaware offers fee waivers through In Forma Pauperis applications for individuals with income at or below 150% of the federal poverty level (approximately $23,895 for a single-person household in 2026). Applicants submit an Affidavit in Support of Application to Proceed in Forma Pauperis. If approved, court fees are waived entirely.
Impact of Tax Reform on Delaware Alimony Awards
The elimination of the alimony tax deduction affects divorce negotiations and court awards in Delaware. Under the old rules, a $3,000 monthly alimony payment from a payer in the 32% federal tax bracket cost approximately $2,040 after the tax deduction. The same payment under post-2018 rules costs the full $3,000. This 47% increase in the effective after-tax cost of alimony has led to lower negotiated alimony amounts in many cases.
Delaware courts recognize this shift. Under 13 Del.C. § 1512(c), judges consider the financial consequences to each party, including tax implications. Some Delaware Family Court judges have adjusted awards to reflect the payer's increased after-tax burden, while others maintain that the statutory factors should control regardless of tax treatment. The lack of a fixed formula in Delaware means outcomes vary significantly based on the specific judge and facts of each case.
For divorcing couples, the tax change eliminates one negotiation tool. Previously, couples could structure settlements to maximize the combined tax benefit, with the higher-earning spouse paying more alimony but deducting it. That flexibility no longer exists for post-2018 divorces. Financial planning now focuses on property division strategies, retirement account splits, and qualified domestic relations orders (QDROs) to optimize tax outcomes.
Alimony vs. Child Support: Different Tax Treatment
Child support remains completely tax-neutral regardless of divorce date. The paying parent cannot deduct child support payments, and the receiving parent does not report them as income. This has been the rule since 1942 and was unchanged by the Tax Cuts and Jobs Act. The key distinction between alimony and child support matters for tax reporting and IRS compliance.
In Delaware, child support is calculated using the Melson Formula, a three-step calculation that considers each parent's income, the child's needs, and standard of living adjustments. Unlike alimony, child support follows a mathematical formula rather than judicial discretion. Child support in Delaware typically continues until the child reaches 18 or graduates high school (whichever is later), but courts may order support through college under certain circumstances.
Payments that terminate upon a child reaching majority or that are contingent on events related to the child (such as graduation or marriage) are treated as child support rather than alimony for tax purposes, even if labeled differently in the divorce decree. The IRS looks at substance over form, so parties cannot recharacterize child support as alimony to gain tax benefits in pre-2019 divorces.
Reporting Requirements for Pre-2019 Delaware Divorces
Spouses with divorce agreements finalized before January 1, 2019 must continue following the old tax rules through 2026 and beyond. The paying spouse deducts alimony on Schedule 1 (Form 1040), Line 19a, and must enter the recipient's Social Security number on Line 19b. The recipient reports alimony received on Schedule 1, Line 2a, and must provide the payer's SSN on Line 2b. The IRS cross-references these entries to ensure both parties report consistently.
Failure to include the Social Security number results in a $50 penalty and potential disallowance of the deduction. If the amounts reported by payer and recipient do not match, the IRS will audit one or both parties. Maintaining accurate records of all alimony payments, including canceled checks, bank statements, and court orders, protects both parties during an audit.
Pre-2019 agreements may be modified to adopt the new tax treatment, but only if the modification specifically states that the Tax Cuts and Jobs Act rules will apply. General modifications that change payment amounts do not automatically trigger the new rules. Both parties must agree to opt into the new tax treatment, which may benefit lower-income payers but harm higher-income payers who lose the deduction.
Cohabitation and Remarriage: Alimony Termination Rules
Delaware alimony automatically terminates upon remarriage of the recipient under 13 Del.C. § 1512(f). The obligation also ends if the recipient begins cohabiting with another adult in a relationship where they hold themselves out as a couple, regardless of whether the arrangement provides financial benefit. This definition captures both romantic partnerships and arrangements that functionally resemble marriage without legal formalization.
Cohabitation must involve regularly residing together, not occasional overnight stays. Delaware courts examine factors such as shared finances, joint accounts, shared household responsibilities, and public acknowledgment of the relationship. The payer bears the burden of proving cohabitation to terminate alimony. Courts have terminated alimony when recipients shared residences with partners for extended periods, even when the recipient denied the romantic nature of the relationship.
Parties may contractually agree to different termination provisions. A separation agreement might provide that alimony continues for a fixed term regardless of remarriage or cohabitation, or it might expand termination triggers. These agreements are enforceable unless the court finds them unconscionable at the time of execution.
