Types of Alimony in Iowa
Iowa courts may award the following types of alimony:
- Iowa recognizes three primary types of spousal support plus temporary support: (1) Traditional spousal support — long-term or indefinite support for spouses who cannot become self-supporting due to age
- health
- or extended absence from the workforce; typically reserved for long-duration marriages. (2) Rehabilitative spousal support — temporary support to help a spouse acquire education
- training
- or skills to become self-supporting; the court usually requires the recipient to submit an employment plan. (3) Reimbursement spousal support — compensates a spouse who financially supported the other’s education or career development during the marriage (e.g.
- working while the other attended professional school). (4) Temporary (pendente lite) spousal support — awarded while the divorce is pending to maintain the status quo until the decree is finalized. Iowa does not use the terms “bridge-the-gap” or “durational” as formal categories.
How Iowa Calculates Alimony
Iowa does not have a fixed formula for calculating alimony. Courts use judicial discretion, weighing multiple factors to determine a fair amount and duration.
Iowa courts consider these factors when determining alimony:
- Under Iowa Code § 598.21A
- the court considers ALL of the following factors: (a) The length of the marriage. (b) The age and physical and emotional health of the parties. (c) The distribution of property made pursuant to § 598.21. (d) The educational level of each party at the time of the marriage and at the time the action is commenced. (e) The earning capacity of the party seeking maintenance
- including educational background
- training
- employment skills
- work experience
- length of absence from the job market
- responsibilities for children under either an award of custody or physical care
- and the time and expense necessary to acquire sufficient education or training to enable the party to find appropriate employment. (f) The feasibility of the party seeking maintenance becoming self-supporting at a standard of living reasonably comparable to that enjoyed during the marriage
- and the length of time necessary to achieve this goal. (g) The tax consequences to each party. (h) Any mutual agreement made by the parties concerning financial or service contributions by one party with the expectation of future reciprocation or compensation by the other party. (i) The provisions of an antenuptial agreement. (j) Other factors the court may determine to be relevant in an individual case.
Income disparity: YES. Iowa requires a showing of financial need and the other party’s ability to pay. Under § 598.21A, the court examines the earning capacity of the party seeking support, their ability to become self-supporting at a standard of living reasonably comparable to that enjoyed during the marriage, and the distribution of property. If both spouses have comparable incomes and resources post-divorce, spousal support is unlikely to be awarded.
Vocational evaluation: YES. Iowa courts may use vocational evaluations to assess a spouse’s earning capacity when determining spousal support. Courts focus on what a spouse can earn, not just what they currently earn. A vocational evaluation examines educational background, transferable skills, work history, labor market conditions, and physical/mental limitations. Courts may impute income based on vocational findings, and support may be structured with step-downs if the evaluation shows the recipient can gradually increase their earning capacity.
Iowa Alimony Duration Guidelines
Iowa has no statutory duration guidelines or formula tied to length of marriage. Duration is entirely within judicial discretion. In practice, rehabilitative support typically lasts 1 to 3 years. Traditional support after long marriages (20+ years) may continue indefinitely until death of either party or remarriage of the recipient. However, these are case-law patterns, not codified thresholds.
| Marriage Length | Typical Alimony Duration |
|---|---|
| Short-term (under UNVERIFIED — Iowa statute does not define a short marriage threshold. No codified number of years.) | Rehabilitative or bridge-the-gap; limited duration |
| Moderate-term | Durational alimony; set period based on marriage length |
| Long-term (UNVERIFIED — Iowa statute does not define a specific long-term marriage threshold. Case law generally treats marriages of 20+ years as long-term for purposes of traditional (potentially permanent) support, but this is not codified.+) | May qualify for permanent or indefinite alimony |
Permanent alimony: YES. Iowa allows traditional spousal support for an indefinite duration. Courts typically award permanent/indefinite support in long-duration marriages where one spouse is unlikely to become self-supporting due to age, health, or extended absence from the workforce. Traditional support continues until the death of either party or the remarriage of the recipient, unless otherwise modified.
Modifying & Terminating Iowa Alimony
Modification: YES. Under Iowa Code § 598.21C, spousal support orders may be modified when there is a substantial change in circumstances. The court considers: changes in employment, earning capacity, income, or resources of a party; remarriage of a party; receipt of assistance under government programs; changes in the medical expenses of a party; changes in the number or needs of dependents; changes in the residence of a party; possible support of a party by another person; and other relevant factors. The party seeking modification bears the burden of proving the substantial change. Modification is initiated by filing a petition with the court that issued the original divorce decree.

Cohabitation: Cohabitation by the recipient does NOT automatically terminate spousal support in Iowa. However, under Iowa Code § 598.21C, “possible support of a party by another person” is a factor the court considers in modification proceedings. A recipient’s cohabitation with a new partner can justify a petition to reduce or terminate support, but the payor must file a modification petition and demonstrate a substantial change in circumstances. Cohabitation alone is not an automatic trigger.
Remarriage: Remarriage of the recipient spouse automatically terminates spousal support in Iowa under Iowa Code § 598.21C. No court petition is required — termination is automatic upon the recipient’s remarriage. The paying spouse’s remarriage does NOT automatically terminate the obligation, though it may serve as grounds for a modification petition.
Retirement: The payor’s retirement can constitute a substantial change in circumstances warranting modification of spousal support under Iowa Code § 598.21C. Courts recognize that retirement typically reduces the payor’s income (even with Social Security, pensions, or 401(k) distributions). A retired payor may petition for reduction or termination of alimony. Courts evaluate whether the retirement was voluntary or mandatory, whether it was made in good faith (not solely to avoid alimony), and the payor’s remaining financial resources. There is no automatic termination upon retirement — it requires a modification petition.
Tax Implications of Iowa Alimony
Under the Tax Cuts and Jobs Act (2017), for divorce agreements executed after December 31, 2018, alimony payments are not deductible by the paying spouse and not taxable income for the receiving spouse at the federal level. This applies to all Iowa divorces finalized after that date.
For divorces finalized before 2019, the old rules still apply unless the agreement is modified to adopt the new tax treatment.
Impact of Misconduct on Iowa Alimony
Adultery: Adultery has NO direct impact on alimony awards in Iowa. Iowa is a pure no-fault divorce state — the only ground for divorce is that the marriage is irretrievably broken. Courts have explicitly held that fault, including adultery, is not a factor in spousal support determinations. The purpose of alimony is financial support, not punishment. However, if a spouse dissipated marital assets on an extramarital relationship (e.g., spending marital funds on trips, gifts, or jewelry for a paramour), the court may consider that economic waste in the property division, which can indirectly affect the overall financial picture.
Other marital misconduct: NO. As a pure no-fault state, Iowa does not consider marital misconduct of any kind (adultery, cruelty, abandonment, substance abuse, etc.) when determining spousal support. The statutory factors in § 598.21A are exclusively financial and practical in nature. Fault-based conduct is irrelevant to alimony awards. The only exception is economic misconduct (dissipation of marital assets), which can affect property division under § 598.21.
Additional Iowa rules: (1) Iowa is a pure no-fault state — fault and misconduct are completely irrelevant to alimony. (2) There is no statutory formula, guideline chart, or duration cap — everything is judicial discretion. (3) The 2025 Iowa Acts, Chapter 57, amended subsection 8 of the modification statute (§ 598.21C), effective for support orders entered or pending on or after July 1, 2025; the specific details of this amendment relate to support modification procedures. (4) Either spouse may receive spousal support regardless of gender. (5) Iowa courts strongly favor rehabilitative support over traditional support, encouraging self-sufficiency. (6) Reimbursement alimony is non-modifiable once awarded, unlike traditional and rehabilitative support. (7) Temporary support during the divorce proceeding is separate from the final support award and ends when the decree is entered.
