Alimony in Iowa.

Whether the state sets a formula or leaves it to the judge, what the court has to weigh, how long it runs, and what brings it to an end.

Does Iowa have an alimony formula?
No. The judge decides it on the factors.

No formula, cap or presumptive amount for spousal support, in the Code or in any statewide court rule found on the Iowa Judicial Branch's own site. Iowa's child support guidelines are statutory and presumptive under Iowa Code s. 598.21B, and s. 598.21C(2)(a) makes a ten per cent variance from them a substantial change of circumstances by operation of law; s. 598.21A creates no equivalent for spousal support and names no number of any kind.

Use the state’s own words

Iowa calls it spousal support. Iowa Code s. 598.21A is captioned 'Orders for spousal support'; the body of the section calls the claimant 'the party seeking maintenance' and the modification section, s. 598.21C, is captioned 'Modification of child, spousal, or medical support orders'. Iowa also recognizes a separate action for 'separate maintenance' (s. 598.28).. Using the state’s own term matters when you are searching for forms or reading an order — the words are not interchangeable across state lines, and some of them mean different things in different places.

What the law actually says

Iowa Code s. 598.21A(2): 'Necessary content of order. Orders made pursuant to this section need mention only those factors relevant to the particular case for which the orders are made but shall contain the names, birth dates, addresses, and counties of residence of the petitioner and respondent.' Temporary support, Iowa Code s. 598.10(1)(a): 'The court may order either party to pay the clerk a sum of money for the separate support and maintenance of the other party and the children and to enable such party to prosecute or defend the action. …'.

What the judge has to weigh

Iowa Code s. 598.21A (orders for spousal support); s. 598.21C (modification); s. 598.10 (temporary orders); s. 598.11 (how temporary order made); s. 598.28 (separate maintenance and annulment) — the factorsIowa Code s. 598.21A(1): '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 section 598.21. d. The educational level of each party at the time of 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.'

How long it lasts

Duration

No. Iowa Code s. 598.21A(1) authorizes support 'for a limited or indefinite length of time'. 'The length of the marriage' is factor (a), but no bracket, presumption or maximum is keyed to it. The commonly used Iowa vocabulary of traditional, rehabilitative and reimbursement spousal support does not appear in the statute at all; those categories come from decisions of the Iowa appellate courts.

Does behavior matter?

Marital misconduct

Not addressed. Iowa Code ss. 598.21A and 598.21C contain no fault factor and no fault bar, and neither mentions adultery or desertion. The only nearby fault provision points the other way and concerns the dissolution itself: Iowa Code s. 598.18 is captioned 'Recrimination not a bar to dissolution of marriage'.

When it ends, and when it can change

What brings it to an end

Not addressed. Iowa Code chapter 598 contains no provision terminating spousal support on death, remarriage, cohabitation or retirement. The chapter's full section list was read, and the sections that might have carried such a rule were read in full: s. 598.20, captioned 'Forfeiture of marital rights', provides only that 'When a dissolution of marriage is decreed the parties shall forfeit all rights acquired by marriage which are not specifically preserved in the decree', and expressly does not disturb the support sections; ss. 598.20A and 598.20B are beneficiary-revocation provisions for life insurance and retirement accounts, not support provisions. Iowa instead routes remarriage and support by a new partner through modification, as factors: Iowa Code s. 598.21C(1)(g), 'Remarriage of a party', and s. 598.21C(1)(h), 'Possible support of a party by another person'. Neither terminates anything of itself. A temporary order has its own end point, Iowa Code s. 598.11(2): 'If the order is not so modified, it shall continue in force and effect until the action is dismissed or a decree is entered dissolving the marriage.'

Changing it later

Iowa Code s. 598.21C(1): 'Criteria for modification. Subject to 28 U.S.C. s. 1738B, the court may subsequently modify child, spousal, or medical support orders when there is a substantial change in circumstances. In determining whether there is a substantial change in circumstances, the court shall consider the following: a. Changes in the employment, earning capacity, income, or resources of a party. b. Receipt by a party of an inheritance, pension, or other gift. c. Changes in the medical expenses of a party. d. Changes in the number or needs of dependents of a party. e. Changes in the physical, mental, or emotional health of a party. f. Changes in the residence of a party. g. Remarriage of a party. h. Possible support of a party by another person. i. Changes in the physical, emotional, or educational needs of a child whose support is governed by the order. j. Contempt by a party of existing orders of court. k. Entry of a dispositional or permanency order in juvenile court pursuant to chapter 232 placing custody or physical care of a child with a party who is obligated to pay support for a child. … l. Other factors the court determines to be relevant in an individual case.' Whether the parties may agree that spousal support is non-modifiable is not addressed by the statute.

Worth knowing about Iowa

Two things. First, Iowa is one of the few states to make an antenuptial agreement an express factor in the spousal support award itself rather than a separate contractual question: s. 598.21A(1)(i), 'The provisions of an antenuptial agreement.' Second, s. 598.21A(1)(h) makes a factor of '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' — the classic put-a-spouse-through-school bargain, written into the statute as a factor rather than left to a reimbursement doctrine.

The tax rule changed, and most guides still describe the old one

For a divorce or separation instrument executed after 31 December 2018, alimony is not deductible by the person paying it and not taxable to the person receiving it. The Tax Cuts and Jobs Act repealed the provisions that made it otherwise. For an instrument executed on or before that date the old treatment continues — deductible to the payer, taxable to the recipient — unless it is later modified and the modification expressly adopts the new rule.

This is not a detail. Under the old rule a higher-rate payer could transfer income to a lower-rate recipient and the two of them shared the saving. That saving no longer exists, which changes what a given number is worth to each side. New Hampshire wrote the point into its own statute: its 23 per cent figure assumes non-deductibility, and reverts to 30 per cent if the federal treatment is ever restored.

Alongside the federal rule, Iowa’s own income tax follows the federal treatment. That means the federal answer above is the whole answer here — no state adjustment for alimony either way. Four states do not — Arkansas, California, New Jersey and New York — so this is worth knowing rather than assuming. The fifty-state table.

A straight answer about money is more useful than most advice, and it costs nothing to pass along. Nothing here asks for their real name, and nobody finds out they looked.
