FTB Publication 1005: California Pension and Annuity Guidelines Explained

FTB Publication 1005 is a guidance document issued by the California Franchise Tax Board that explains how pension and annuity income should be reported on a California state income tax return. Unlike a standard fillable tax form, this publication works as a reference tool packed with worksheets, examples, and instructions to help taxpayers and preparers figure out the taxable portion of retirement distributions under California law, which doesn’t always match federal rules.

If you receive income from a pension plan, an annuity, an IRA, or certain other retirement arrangements, this publication walks you through how California treats that income differently from the IRS in specific situations. This matters because some contributions or distributions that are fully taxable federally may have a different basis calculation for state purposes, especially for people who contributed to a plan before certain tax law changes, or who moved to California after establishing a retirement account elsewhere.

Who Needs This Publication

FTB Publication 1005 is mainly useful for:

• Retirees receiving pension or annuity payments who need to determine the taxable amount for their California return.
• Taxpayers who made after-tax contributions to a retirement plan and need to calculate their cost basis.
• People who moved into or out of California and need to understand how residency affects the taxability of retirement income.
• Tax preparers and accountants who handle California returns involving distributions from pensions, annuities, IRAs, or similar plans.

Because retirement income rules can get complicated when contributions were made across multiple states or under different tax treatments, this publication is often used alongside other state schedules and worksheets during return preparation, similar to how taxpayers reference detailed instructions when claiming specialized credits, such as those explained in guides for Form IT-241 or Form IT-237, where following the worksheet order carefully makes a real difference in the final calculation.

When Is It Used

You’ll typically turn to FTB Publication 1005 when preparing your annual California income tax return, particularly if you’ve started receiving retirement distributions for the first time, if you rolled funds into a new plan, or if you’re unsure whether the taxable amount reported on your federal 1099-R matches what California expects. It’s also relevant for taxpayers going through an audit or amending a prior return where pension income was reported incorrectly.

The guidelines cover various types of plans, including private employer pensions, government pensions, military retirement pay, and commercial annuities. Because tax treatment can vary depending on the plan type and contribution history, the publication breaks down separate worksheets for different scenarios rather than offering a single generic formula.

How to Get and Use the Publication

FTB Publication 1005 is available directly from the California Franchise Tax Board’s website as a PDF document. The version applicable to your filing year should be used since the FTB updates the guidance periodically to reflect current law and contribution limits. The document includes fillable digital fields (AcroForm), meaning you can complete relevant worksheets directly on your computer before printing or saving your calculations for your records.

To use it effectively, start by identifying which category best describes your retirement income source, then follow the corresponding worksheet step by step. You’ll need supporting information such as your 1099-R, records of any after-tax contributions, and details about when you established the plan. Once you’ve calculated the taxable portion under California rules, that figure gets transferred to the appropriate line on your California resident or nonresident tax return.

Taxpayers who also claim state-specific credits, like those detailed in resources covering conservation easement tax credits, often find that keeping organized documentation for each calculation, whether it’s a credit claim or a pension basis worksheet, makes the entire filing process smoother and reduces the chance of errors that could trigger a follow-up notice from the FTB.

Because this is a reference publication rather than a form you submit with your return, there’s no separate filing requirement. You keep your completed worksheets for your own records and simply report the calculated taxable amount on your state tax return, ready to provide documentation if the FTB ever requests it.
