Starting March 1, 2026, New York uses its maintenance formula on the first $241,000 of the income of the spouse who has the obligation to pay maintenance. For income above $241,000, courts determine maintenance by balancing the maintenance factors set out in the maintenance statute. The cap applies only to the income of the spouse who pays maintenance, and the formula still takes the other spouse’s income into account.
Some states that use formula-driven approaches to alimony also set an income limit. Formulas add structure and transparency for incomes near the middle of the range, but judges typically exercise greater discretion once income passes the formula’s cap. That discretion can make outcomes less predictable and litigation more costly.
New York Runs a Formula Until It Does Not
For paying spouse income under the threshold, two potential formulas apply. One of the formulas is for paying spouses who also pay child support to the receiving spouse. This formula calculates 20% of the paying spouse’s income, subtracting 25% of the receiving spouse’s income. The other formula applies when no child support is paid and subtracts 20% of the payee’s income from 30% of the payor’s income.
In both cases, the result is compared to 40% of the combined income minus the payee’s income, and the lower figure is used. The duration of post-divorce spousal maintenance is dependent on how long the spouses were married.
If the marriage lasted up to fifteen years, maintenance could be ordered for between 15% and 30% of the marriage duration. For marriages lasting between fifteen and twenty years, spousal maintenance is expected to run for 30% to 40% of the duration. For marriages with a duration of more than twenty years, maintenance may run for 35% to 50% of the marriage duration. The periods mentioned above are just guides. Court decisions are guided by factors that include, but are not limited to, the ones listed in the statutes.
The statutory formula and the $241,000 cap apply statewide, so a high-income maintenance case in Manhattan follows the same framework as one filed elsewhere in New York. Litigants there may retain a Manhattan spousal support lawyer from a firm that lists high-asset divorce, property division, and appeals alongside spousal support.
California Runs No Long-Term Formula at All
The West Coast version works differently. Temporary support is commonly set by guideline software, but temporary support orders usually differ from permanent support orders. Permanent support is based on California’s statutory factors, which courts weigh without a set formula. In any event, most formulas posted online provide guidance on setting temporary support orders and not final support orders.
How judges calculate alimony in high-income divorces depends on the factors a court considers. These factors vary between cases, so most of these cases involve substantial evidentiary preparation by both parties. California State Bar certification as a family law specialist is one of the few objective markers of experience in this field.
The Tax Answer Depends Entirely on the State
Federal treatment has been settled since the 2017 overhaul. For agreements executed after December 31, 2018, the payor deducts nothing and the recipient reports nothing. States then went their own directions. New York did not follow the federal change, so for agreements executed after December 31, 2018, a payor subtracts the payments from federal adjusted gross income for state purposes, and a recipient adds them back.
California moved the opposite way in 2026. For orders made on or after January 1, 2026, a payor there can no longer deduct spousal support on a state return and a recipient no longer reports it, closing a gap that had run since the federal repeal. Two of the highest-cost states in the country now treat the same payment in opposite ways, which matters enormously at high income.
What Drives the Number Above the Cap
These considerations often come down to the court’s discretion, which the court exercises after the parties have argued them. They may include the standard of living established during the marriage, the length of the marriage, the recipient’s earning capacity, the time needed to reach it, one spouse’s contributions to the other’s career or credentials, and the payor’s ability to pay.
The payor’s ability to pay can take the most time. A salary is straightforward to establish. Partnership distributions, deferred compensation, restricted stock vesting over several years, carried interest, and personal expenses paid through a closely held company are harder to pin down. In high-income cases, the dispute over the payor’s actual earnings can run longer than the dispute over the recipient’s needs.
Why Predictions Keep Failing
Two households reporting identical income can land far apart. Take, for example, a situation in which one marriage lasted twenty-two years, with a spouse who left a career at year three. Another marriage ran six years with two earners and no gap. The statutory factors carry no assigned weights, so a judge’s sense of which ones matter most becomes the outcome rather than an input to it.
In any litigation, because factors aren’t valued uniformly, evidence must be introduced in order to achieve the desired result. The evidence used to defend any position in any forum will be guided by an already established framework, such as an income ceiling or other applicable formulas.
