California Adjusted Basis in a 1031 Exchange

Confirm legal owner, tax owner, acquisition date, ownership percentage, entity classification, parcels, buildings, and personal property. Separate property not included in the exchange.

A basis schedule for one entity cannot be borrowed by another merely because management is shared.

Gather closing statements, purchase agreement, assumed liabilities, legal, title, recording, commissions, and capitalized acquisition costs. Allocate land, buildings, and other assets.

Use supported allocations consistent with depreciation and prior returns.

Track additions, remodels, roofs, systems, site work, tenant improvements, fees, permits, and construction-period costs. Link invoices, dates, and placed-in-service records.

Repairs deducted currently should not be added again. Review classification with tax advisers.

Reconcile federal and California depreciation schedules, methods, lives, conventions, and prior adjustments. Include assets removed or replaced.

Basis and recapture can be affected by depreciation that should have been claimed even if records are incomplete. Obtain professional analysis.

Review casualty losses, insurance proceeds, restoration, involuntary conversions, basis reductions, and replacement property. Reconcile tax returns and fixed assets.

Do not add rebuilding cost without accounting for proceeds and prior adjustments.

Review condemnations, easements, parcel splits, air rights, mineral rights, conservation restrictions, partial sales, and property received. Allocate basis to the interest disposed.

One parcel number can contain several tax assets after years of transactions.

Obtain earlier Forms 8824, closing statements, recognized gain, boot, replacement basis, debt, and later improvements. Reconstruct the chain.

A low current basis may originate in property sold decades earlier. Preserve that history for California source reporting.

Review date-of-death appraisals, estate returns, trust distributions, gift-tax records, donor basis, prior depreciation, community property, and entity ownership with advisers.

Do not assume purchase price when the owner acquired property by gift or death. California and federal results require the actual history.

Separate inside property basis, partner outside basis, capital accounts, Section 704(c), Section 754 or 743 adjustments, liabilities, and the taxpayer that completes the exchange.

A partnership's property exchange cannot be modeled from one partner's outside basis, and a partner's interest sale is not the same asset.

Review energy, rehabilitation, low-income housing, grants, reimbursements, cancellation, and other items that may alter basis. Reconcile forms and depreciation schedules.

Gross construction cost can overstate basis when public or insurance funding changes the amount capitalized.

For improvement exchanges, track land, work completed while held by the accommodation titleholder, invoices, deadlines, value, and taxpayer ownership. Coordinate with exchange counsel.

Costs paid or work completed after the taxpayer receives property may not enter exchange value the same way.

For every unsupported amount, state the assumed range, evidence searched, adviser conclusion, and effect on gain and reinvestment. Do not hide uncertainty inside one precise basis number.

Use sensitivity to decide whether further records, amended returns, or conservative reporting are needed.

County assessments, transfer declarations, and property-tax values can help identify parcels and changes, but they do not automatically establish federal or California income-tax basis.

Use them as corroborating records, explain differences, and preserve the evidence supporting the tax allocation actually used.

Compare depreciation, conformity, credits, elections, personal-property history, and entity adjustments. Use current California forms and professional advice.

One federal basis schedule may not answer every California return line.

Reconcile sales price, liabilities, closing costs, commissions, basis, and property transferred. Separate cash, notes, services, and other property.

The realized gain establishes the ceiling; recognized gain depends on exchange consideration and applicable rules.

Use the supported federal exchange calculation for basis in property received, including deferred gain and recognized amounts. Reconcile to Form 8824 and FTB 3840 where applicable.

Replacement cost and tax basis are different numbers. Both should be visible.

Document values, consideration, debt, classes, ownership, and allocation method for each replacement asset. Maintain separate depreciation schedules.

An unsupported equal allocation can distort later sale, depreciation, and California deferred-gain tracking.

Obtain appraisal, county assessment, cost, and other defensible evidence. Coordinate with depreciation and purchase accounting.

Do not assign minimal land merely to increase depreciation. The allocation should survive future review.

Identify retained cash, notes, debt relief, non-like-kind property, and transaction costs. Calculate recognized gain and resulting basis with advisers.

Spending more cash does not automatically cure every debt or boot issue. Use the full formula.

When California property is exchanged for out-of-state property, reconcile initial and annual FTB 3840 records to basis, deferred California gain, later improvements, and dispositions.

Moving property or taxpayer does not erase the need for a continuous schedule.

Retain deeds, closings, invoices, depreciation, returns, exchanges, casualties, partial sales, and allocations by asset. Reconcile annually.

Do not wait for a sale to discover that old records were discarded under a shorter bookkeeping policy.

Show beginning cost, each addition, each reduction, current adjusted basis, realized gain, recognized gain, deferred gain, and replacement basis. Cite source records.

List unresolved assumptions and sensitivity. A clean bridge turns a tax estimate into a defensible exchange input.
