California Homeowner Tax Planning: Questions Before You Borrow

Budget the payment before estimating a tax benefit

A mortgage payment is due on its own schedule. A possible tax deduction does not reduce that monthly obligation automatically. Build a budget you can carry before any expected refund, then ask a qualified tax professional whether the loan changes your federal or California tax position.

Bring the tax year, filing status, intended use of the home and use of borrowed funds to that discussion. ECHL can supply loan estimates and explain financing terms. Tax advice and return preparation belong with your tax professional.

Separate the taxes involved

Property tax concerns the parcel and its assessed value. Income tax concerns taxable income and the rules for the relevant filing year. Sales and use tax may affect furnishings or purchases associated with a move or renovation. These are different systems; a county property-tax average tells you little about the others.

Use the California Department of Tax and Fee Administration's address-based lookup and effective-date information for applicable sales and use tax rates. City names alone can be misleading where district boundaries differ. CDTFA: Current tax-rate lookup.

Ask what is actually deductible

Mortgage-interest deductions depend on the applicable debt rules, qualified home, itemization and use of proceeds. Interest on equity borrowing does not become deductible simply because the home secures the debt. Keep records that trace funds to their use and have your tax professional apply the rules for the return being prepared. IRS Publication 936.

California does not conform to every federal itemized-deduction rule. Avoid carrying a federal answer directly onto a state return or assuming an old state-and-local-tax limit remains current. Have your adviser use the applicable year's instructions, filing status and income limitations. FTB: California deductions.

Plan before a sale, transfer or refinance

California generally taxes capital gains as ordinary income rather than applying a separate lower capital-gains rate. The taxable amount still depends on basis, exclusions and the transaction. A home sale, rental sale and qualifying exchange can have different consequences. Obtain a transaction-specific review before treating proceeds as fully available for the next purchase. FTB: Capital gains and losses.

Property-tax reassessment is another question. Proposition 19 relief has eligibility and filing conditions; inherited property does not automatically retain the former owner's assessment. Coordinate ownership changes with the appropriate legal and tax advisers before recording documents.

Build a useful document packet

• Loan Estimate or Closing Disclosure and the note.
• Purchase and sale settlement statements.
• Mortgage-interest statements and property-tax bills.
• Records of refinance or equity-loan proceeds.
• Improvement invoices, permits and dates.
• Any exemption, reassessment or ownership-transfer notices.

Compare financing on its borrowing cost and payment risk first. Then add only the tax effects your adviser can support. Paying more interest solely to obtain a deduction can leave you with a larger after-tax cost.
