Imputed income: when a court uses earnings a parent could have.

Imputation means using an income figure other than what a parent is currently earning, usually because the court finds the parent is voluntarily unemployed or underemployed. It is one of the most disputed parts of a support case, and federal law now limits how it can be done.

What federal law requires

States may authorize imputation, but under 45 CFR 302.56(c)(1)(iii) the guideline must take into account the specific circumstances of the parent, to the extent known. The regulation lists those circumstances:

• assets and residence
• employment and earnings history
• job skills, educational attainment and literacy
• age and health
• criminal record and other employment barriers
• record of seeking work
• the local job market, the availability of employers willing to hire the parent, and prevailing earnings levels in the community

The same regulation, at 302.56(c)(3), provides that incarceration may not be treated as voluntary unemployment when an order is established or modified. A court therefore cannot impute pre-incarceration earnings simply because a parent is in jail or prison.

Common situations that lead to imputation

A parent leaves a job during the case

Courts look closely at a resignation or a move to lower-paid work shortly before or during a support case. The South Carolina guide on this site notes that imputation is common when a parent leaves the workforce during a case.

Seasonal or irregular work

North Dakota disputes often involve seasonal earnings, where the question is whether to average a full year rather than use an off-season month.

Underemployment

New Mexico, Oklahoma and other states allow imputation when a parent is working below their demonstrated earning capacity without a good reason.

Income from assets

Some states, such as Vermont, can impute a reasonable return on assets that are not producing income.

Reasons that often weigh against imputation

The specific facts matter. Courts commonly consider a documented disability or health condition, caring for a young child or a child with special needs, full-time education that is expected to raise earnings, a layoff with a record of job applications, and local labor-market conditions. Keep the evidence: medical records, termination letters, application logs and school enrollment.

How to model imputation with a calculator

A calculator cannot decide whether income should be imputed. That is a finding for the court or agency. What you can do is run two scenarios side by side: one with actual current income, and one with the figure the other parent proposes, such as prior earnings or full-time work at a stated wage. Label each scenario clearly in the printed report so no one mistakes an assumption for a documented amount.

If the dispute is over a minimum-wage figure, check whether your state guideline names a specific number of hours. Many use full-time hours at the applicable minimum wage, while others leave the hours to the court.

Records to gather

• Three or more years of tax returns, W-2s and 1099s to show earnings history.
• Termination, layoff or resignation documents and the reasons given.
• Job search records with dates, employers and responses.
• Medical documentation of any condition that limits work.
• Local wage data for the occupation, if the proposed imputed figure is disputed.
