What Cost-Basis Records Should You Keep for Assets Received in Divorce?
The divorce settlement may list the house at $800,000 and a brokerage account at $600,000. Those values helped divide property. They do not necessarily tell you what gain or loss you will report when an asset is sold.
That later calculation may depend on purchases, reinvestments, improvements, depreciation, and tax lots created years before the divorce. The practical job now is to preserve the history while former account access, shared files, and professional relationships are still available.
Why does the settlement value not become your tax basis?
For a qualifying transfer between spouses or former spouses incident to divorce, federal law generally does not recognize gain or loss at the transfer. The recipient generally takes the transferor’s adjusted basis and holding period. The IRS also says the transferring spouse must provide enough records to determine both.[1]
This carryover treatment preserves the asset’s earlier tax history. If investments worth $300,000 have an adjusted basis of $180,000, receiving them at a $300,000 settlement value generally does not erase the $120,000 embedded gain. A later sale is based on the carried basis, adjusted for events occurring after the transfer—not the negotiated value.[2]
One asset can carry two valid numbers with different jobs
DIVORCE VALUE
Helps compare and divide property at the settlement date.
ADJUSTED TAX BASIS
Carries acquisition history and later adjustments into the future sale calculation.
The settlement can be economically fair while the assets still carry unequal future tax consequences.
Which investment records preserve the missing history?
Ask for the final transfer statement and a tax-lot schedule showing each security, quantity, acquisition date, original cost, adjusted basis, and whether the lot is covered or noncovered. Keep trade confirmations, prior year-end statements, records of stock splits and reorganizations, and evidence of return-of-capital adjustments. Reinvested dividends and capital-gain distributions generally add to investment basis, so preserve the statements that trace those purchases.[3]
Do not assume the receiving custodian has everything. An unknown basis can result when shares move between accounts, and some displayed basis information may omit adjustments.[4] For noncovered shares, the investor remains responsible for reporting basis even when a broker does not report it to the IRS.[5] Compare the received lots with the settlement schedule before the former account is closed. Resolve missing or mismatched lots with the transferring firm, receiving firm, and tax professional, and retain the evidence supporting any customer-provided correction.
Dovetail Principle: Information Should Show What Changes for You
A settlement value explains how property was divided. Basis records explain how a future sale may affect your taxes. Keeping those two jobs separate turns a folder of old documents into usable decision information.
What should remain with real estate and other property?
For a home or other real estate, keep the original purchase closing statement, deed and title history, settlement agreement, transfer documents, and records of costs that affected basis. Preserve invoices and proof of payment for capital improvements—not merely a list or an appraisal. Home-sale guidance specifically calls for records supporting adjusted basis.[6]
If the property was ever rented or used for business, collect depreciation schedules, prior returns, dates placed in and removed from service, and records of improvements and casualty adjustments. Depreciation allowed or allowable can reduce basis even if the deduction was overlooked, which makes prior tax-return support especially important.[7]
For closely held business interests, collectibles, stock compensation, partnerships, or property with debt, request an asset-specific basis analysis. These assets may involve contribution history, prior income allocations, depreciation, compensation income, or other adjustments that an account statement cannot reconstruct. Keep the divorce decree and property-settlement schedules as the bridge showing why ownership changed, but do not treat them as the full tax ledger.
When is the record set complete enough?
Build one basis file for each material asset. Start with the transferred interest’s acquisition date and basis immediately before the transfer. Add documents for every later increase or decrease. Tie the total to the quantity, ownership percentage, or legal description you actually received. Then ask your tax professional whether the file can support a future Form 8949, a home-sale calculation, a depreciation schedule, or another applicable return.
Keep basis records for as long as you own the property and through the applicable limitations period after the return reporting its sale. Digital copies should be complete, readable, securely backed up, and named so the asset and date can be found.[8] The decision is not how much paper to retain. It is whether someone can reproduce the asset’s tax history before a sale turns that history into a required number.
