If you are going through a divorce or legal separation in California, you will almost certainly need to complete an Income and Expense Declaration. This financial disclosure form — officially known as California Judicial Council Form FL-150 — is one of the most important documents in your entire case.
Judges rely on the information you provide to calculate child support, spousal support (alimony), and attorney fee awards. Getting it wrong can directly cost you money.
This guide explains what the Income and Expense Declaration is, how it connects to the FL-150 form, what documents you need to gather, and the most common mistakes that cause problems in court.
California’s Income and Expense Declaration (Form FL-150) is a mandatory financial disclosure that reports your income, expenses, assets, and debts to the family court. Judges use it to calculate child support and spousal support using California’s guideline formula. Every party in a divorce or family law case involving financial support must file one.
What Is the Income and Expense Declaration?
The Income and Expense Declaration is California’s standardized form for financial disclosure in family law cases. When you hear attorneys or court clerks refer to the “FL-150,” they are talking about this form.
The form captures four main categories of financial information:
- Income — wages, salary, self-employment earnings, investment returns, government benefits, and any other source of money you receive
- Expenses — your monthly cost of living including housing, food, transportation, healthcare, childcare, and debt payments
- Assets — a summary of what you own (bank accounts, retirement accounts, real estate, vehicles)
- Debts — what you owe (mortgage, car loans, credit cards, student loans)
The court uses this information to run California’s guideline support calculation. Without a properly completed FL-150, the judge cannot determine the correct support amount. For a comprehensive overview of the FL-150 — including its history, filing triggers, and how it affects support — see our complete FL-150 guide. For detailed instructions on completing each section of the form, see our step-by-step FL-150 form instructions.
Why the Income and Expense Declaration Matters
The FL-150 is not just paperwork — it directly affects your financial outcome. Here is why it matters:
Child Support Calculation
California uses a mathematical formula (the “guideline calculation”) that takes each parent’s income, time-share percentage, tax filing status, and certain deductions to produce a presumptively correct child support amount. The numbers you put on your FL-150 feed directly into this formula.
Spousal Support Determination
For temporary spousal support, most counties use a formula similar to the child support guideline. For long-term spousal support after trial, judges consider the factors listed in Family Code Section 4320, many of which depend on the financial information disclosed in your FL-150.
Attorney Fee Awards
Under Family Code Section 2030, the court can order one party to pay the other’s attorney fees based on the relative financial positions disclosed in the FL-150. If your declaration shows significantly more income and assets than the other party, you may be ordered to contribute to their legal costs.
Credibility with the Judge
Family law judges review hundreds of FL-150s. They can spot inconsistencies, inflated expenses, and unreported income. Filing an honest, thorough, and accurate declaration establishes your credibility — which matters for every ruling the judge makes in your case.
What Documents You Need
Before you sit down to complete the Income and Expense Declaration, gather these documents. Having everything in front of you will make the process faster and reduce errors.
Required Attachments (Mandatory)
California Family Code Section 2104 requires these attachments:
- Two most recent pay stubs — prove your current income
- Most recent federal tax return — all pages, including W-2s and all schedules
- Most recent California state tax return — Form 540 or 540NR
Missing these attachments can result in the court rejecting your FL-150 or continuing your hearing.
Additional Documents You Should Have Ready
- Proof of non-employment income — Social Security award letters, disability statements, rental income records, investment account statements, pension statements
- Monthly bills and statements — mortgage/rent, utilities, insurance premiums, car payments, credit card statements
- Childcare receipts — daycare, after-school care, summer camp
- Health insurance premium statements — especially if you cover your children
- Business profit and loss statement — if self-employed (last 12 months)
- Bank statements — last 2 months for all accounts
Income Reporting: The #1 Mistake People Make
The single most common error on the Income and Expense Declaration is reporting net income instead of gross income.
Gross income means your total pay before any taxes, retirement contributions, health insurance premiums, or other deductions are taken out. Net income (take-home pay) is what actually hits your bank account.
The FL-150 asks for gross income. The court’s guideline calculation handles deductions separately. If you report your take-home pay, the calculation will understate your income and produce an incorrect support number.
How to Convert Non-Monthly Income to Monthly
The FL-150 requires monthly figures. Here is how to convert:
| Pay Frequency | Conversion |
|---|---|
| Weekly | Multiply by 4.333 |
| Biweekly (every 2 weeks) | Multiply by 2.167 |
| Semi-monthly (twice a month) | Multiply by 2 |
| Annual | Divide by 12 |
| Quarterly | Divide by 3 |
Income Sources You Must Report
Many people forget to include non-employment income. The FL-150 requires disclosure of all income sources:
- Wages, salary, overtime, commissions, bonuses, tips
- Self-employment and freelance income (1099 income, gig work)
- Rental property income
- Dividends, interest, and capital gains
- Social Security, disability (SSDI/SSI), workers’ compensation
- Unemployment benefits
- Pension and retirement distributions
- Trust income and royalties
- Spousal support received (from this or another case)
Expense Reporting: Be Thorough and Honest
The expense section of the FL-150 asks you to itemize your monthly living costs. The court uses this information to assess your financial needs and ability to pay support.
Tips for Accurate Expense Reporting
- Use actual amounts, not guesses. Review your bank and credit card statements for the last 3 months and average them.
- Don’t inflate expenses. Judges see hundreds of these forms. Claiming $2,500 a month in groceries for one person will damage your credibility.
- Don’t forget irregular expenses. Annual car registration, insurance premiums paid quarterly, and holiday costs should be divided by 12 and included as a monthly average.
- Include new expenses if you have separated. If you recently moved out, your housing and utility costs have likely changed. Report your current situation, not your pre-separation costs.
Common Expense Categories
- Housing: Rent or mortgage, property tax, homeowner’s insurance, HOA dues, maintenance
- Utilities: Electric, gas, water, trash, internet, phone
- Food: Groceries, dining out, household supplies
- Transportation: Car payment, gas, insurance, registration, maintenance, parking
- Healthcare: Insurance premiums, co-pays, prescriptions, dental, vision
- Childcare: Daycare, babysitter, after-school programs
- Insurance: Life, disability (if not payroll-deducted)
- Debt payments: Credit card minimums, student loans, personal loans
The FL-150 vs. the FL-155: Which Do You Need?
California offers a simplified financial statement on Form FL-155 for cases that meet specific criteria. The FL-155 is shorter and simpler, but it is only available when:
- Your total annual gross income is under $184,000 (2026 threshold)
- There are no complex financial issues (no business ownership, significant investments, or disputes about income)
- Both parties agree to use the simplified form
If your situation involves self-employment income, business valuations, stock options, or any contested financial issues, you must file the full FL-150. When in doubt, file the FL-150 — it is always accepted.
Filing Timeline and Service Requirements
When to File
You must file the FL-150 in these situations:
- Initial divorce filing — when child support or spousal support is at issue
- Request for Order (RFO) hearings — served at least 16 court days before the hearing
- Domestic violence restraining orders — when requesting financial support
- Post-judgment modifications — when either party seeks to change an existing support order
- Default judgments — even if your spouse never responds, you must file the FL-150
How to Serve Your FL-150
Your completed FL-150 must be served on the other party (or their attorney) at least 16 court days before any hearing where support will be discussed.
Acceptable service methods:
- Personal delivery — by someone other than you (not by mail)
- Mail service — add 5 calendar days for mailing time
- Electronic service — if both parties have consented to e-service
After serving, file a Proof of Service (Form FL-330 or POS-040) with the court.
What Happens If You Don’t File or File Late?
Failing to file the Income and Expense Declaration has real consequences:
- Hearing continuance — the judge may postpone your hearing until you file
- Default income findings — the court may use the other party’s estimate of your income, which is usually unfavorable to you
- Sanctions — the court can impose monetary penalties under Family Code Section 271 for failure to cooperate in the discovery process
- Imputed income — if the court believes you are voluntarily underemployed or hiding income, it can assign you an earning capacity higher than what you actually earn

Frequently Asked Questions
What is the Income and Expense Declaration in California?
The Income and Expense Declaration is California Judicial Council Form FL-150. It is a mandatory financial disclosure form used in divorce, legal separation, and other family law cases. The form requires you to report all income sources, monthly living expenses, assets, and debts so the court can determine child support, spousal support, and attorney fee awards.
When do I need to file an Income and Expense Declaration?
You must file Form FL-150 whenever child support, spousal support, or attorney fees are at issue in your California family law case. This includes initial divorce filings, Request for Order hearings (served 16 court days before the hearing), domestic violence restraining orders with support requests, and post-judgment modification hearings.
What documents do I need for my Income and Expense Declaration?
You need your two most recent pay stubs, your most recent federal and state tax returns (including all schedules and W-2s), proof of any non-employment income (Social Security letters, rental income records, investment statements), monthly bills and statements, and a profit and loss statement if you are self-employed.
Do I report gross income or net income on the FL-150?
You must report gross income (before taxes and deductions), not net or take-home pay. This is the single most common mistake on the FL-150. The court uses California’s guideline formula to calculate deductions separately, so reporting net income will result in an inaccurate support calculation.
What happens if I don’t file my Income and Expense Declaration?
Failing to file the FL-150 can result in your hearing being continued (postponed), the court making support decisions without your input using the other party’s information, sanctions for non-compliance, or the court imputing income based on your earning capacity.
Can I use the simplified FL-155 instead of the FL-150?
The FL-155 (Simplified Financial Statement) is only available when your total annual gross income is under $184,000 (updated 2026 threshold), there are no complex financial issues like business ownership or significant investments, and both parties agree to use it. If any of these conditions are not met, you must file the full FL-150.
