Tax Summary for Spousal Support

Extracts income sources, deductions, tax liabilities, and multi-year trends from tax records to assess financial capacity, ability to pay, or need for support.

Prerequisites

Tax returns — Federal (1040) and state for 2–3 most recent years minimum
Income documents — W-2s, 1099s (all types), K-1s, Schedules C/E/F
Business returns — 1065, 1120-S, or 1120 if party owns business interests
Party identification — Petitioner, respondent, or both
Jurisdiction — State governing support calculation (affects income definitions)

Quick Start

Collect all available tax documents and identify gaps
Determine party and jurisdiction
Follow the output structure below, citing form and line for every figure
Flag support-relevant adjustments where tax income diverges from economic income

Output Structure

1. Executive Overview

Multi-year table with: gross income, AGI, taxable income, total tax liability (fed + state), effective tax rate, net after-tax income, and trend direction (↑/↓/→) for each metric.

2. Income Source Breakdown

Per year, itemize each source with amount, percentage of total, and form/line reference:

Wages (W-2), self-employment (Sch C), business distributions (K-1), rental (Sch E), interest/dividends (Sch B), capital gains (Sch D), retirement distributions, other

3. Tax Liability Analysis

Federal and state obligations separately
Effective vs. marginal rates
Significant credits (child tax, earned income, etc.)
Withholding and estimated payment patterns
AMT exposure if applicable

4. Deductions and Adjustments

Flag support-relevance for each deduction:

Retirement contributions — reduces cash but builds assets
Health insurance (self-employed) — mandatory expense
Business expenses — review for personal benefit
Mortgage interest — lifestyle indicator
Charitable contributions — discretionary capacity
Depreciation — not actual cash outflow; courts often add back

5. Business Income Reconciliation

If self-employed or business owner, reconcile reported taxable income vs. actual economic benefit:

Add back: depreciation, amortization, one-time write-offs, personal expenses through business
Identify owner perks: vehicle, travel, meals, insurance, entity-funded retirement
Compare retained earnings + distributions vs. salary
Determine cash flow available vs. tax-reported income

6. Multi-Year Trend Analysis

Income trajectory (growth, decline, volatility)
Filing status changes and tax impact
Income composition shifts (e.g., W-2 to 1099)
Marital standard of living indicators from expenditure patterns

7. Observations and Flags

Income/lifestyle inconsistencies
Unusual or suddenly changed deduction patterns
Underreported income indicators
Hidden income through entity structures
Need for forensic accounting or expert testimony
Documentation gaps

Pitfalls and Checks

Tax income ≠ support income — Depreciation, accelerated deductions, and pre-tax retirement may be added back for support calculations. Flag explicitly.
Source attribution — Cite tax year, form, and line for every figure (e.g., "2024 Form 1040, Line 9: $185,000").
Filing status transitions — Quantify tax liability difference from MFJ to MFS/Single/HoH; directly affects disposable income post-separation.
Imputed income — If voluntarily underemployed or income appears suppressed, note basis but do not calculate; flag for attorney review.
Limitations — State unavailable documents and how gaps affect analysis. Recommend specific documents that would strengthen the summary.
Neutral tone — Present findings objectively. Advocacy framing is counsel's role.
