Investment and pass-through taxation
Tax records for investments, crypto, and Schedule K-1
Brokerage statements, crypto exports, and Schedule K-1 report different kinds of tax information. None is a substitute for the acquisition, basis, transfer, distribution, and carryover records that explain the return.
Create separate ledgers for securities, digital assets, and pass-through interests, then reconcile the year-end forms to those ledgers before combining anything on the individual return.
The short version
- Preserve basis from acquisition through disposition, including transfers between brokers, exchanges, wallets, or accounts.
- Separate a digital-asset disposition from a transfer between accounts you control and account for fees paid in digital assets.
- Do not treat a Schedule K-1 allocation as cash received or a distribution as proof of taxable income; maintain basis and loss-limit records.
In this guide
Reconcile brokerage proceeds and cost basis
For securities sales, match each Form 1099-B line or brokerage summary to acquisition confirmations, reinvested dividends, corporate-action notices, transfer records, and sale confirmations. Note whether basis was reported to the IRS and whether the holding period and lot are correct. A transfer between brokers can leave the receiving broker without complete historical basis.
Form 8949 reconciles reported proceeds and basis with any necessary return adjustments. Keep a worksheet for inherited or gifted assets, employee stock, wash-sale adjustments, return of capital, mergers, and securities acquired in multiple lots. The required basis depends on how the property was acquired, so a blank or estimated broker field should trigger research rather than a zero-basis assumption.
Classify digital-asset receipts and dispositions
The IRS treats digital assets as property. Record each purchase, receipt, sale, exchange, or other disposition with date and time, units, U.S.-dollar value, fees, account or wallet, transaction identifier, and basis. Exchanging one digital asset for another, spending it on goods or services, or paying a transaction fee with digital assets can create reportable activity even when no dollars return to a bank account.
Receiving digital assets for services, staking, mining, rewards, or another transaction may begin with ordinary-income questions before later disposition reporting. Keep the record of how and when each unit was acquired so the later basis is not reconstructed from a current market value.
Separate self-transfers from changes in ownership
Moving digital assets between wallets or accounts that you own or control is generally distinct from selling or exchanging them. Preserve both sides of the transfer, wallet addresses, transaction identifier, units sent and received, timestamp, and fee. If the fee was paid with digital assets, that payment can itself be a transaction even when the principal moved between your own accounts.
A missing receiving record can make a self-transfer look like a disposal and can break the basis trail. Build a transfer-matching schedule before importing transaction software totals. Transfers to another owner, payments for property or services, exchanges, gifts, and lost access involve different facts and should not be grouped under a generic “transfer” label.
Use Forms 1099-B and 1099-DA as reconciliation inputs
Form 1099-B reports broker information for securities and other covered transactions. Form 1099-DA reports digital-asset proceeds from broker transactions. Neither means that unreported transactions disappear, and a proceeds amount does not by itself state taxable gain. Compare payer, account, asset, proceeds, dates, and basis status with the ledger and request corrections for issuer errors.
Broker digital-asset reporting is evolving, so use the instructions for the specific filing year. Form 8949 instructions distinguish transaction categories based on form and basis reporting. Preserve every form, substitute statement, and exchange export, then document return adjustments rather than changing a source form or forcing an unsupported match.
Separate Schedule K-1 tax items from distributions
A partnership Schedule K-1 reports the partner’s share of income, deductions, credits, and other items whether or not the same amount was distributed in cash. A cash or property distribution affects the partner’s outside basis and can have a different tax result; it is not automatically the year’s taxable income. Keep the complete K-1, every attached statement, contribution and distribution records, ownership changes, and prior-year return workpapers.
The capital account shown on a K-1 may not equal outside tax basis because partner-level items and shares of liabilities can differ. Maintain an annual outside-basis schedule using acquisition or contribution documents, allocated income and loss, distributions, liability changes, and other adjustments. A sale or redemption of the interest requires the same history, not just the final K-1.
Carry forward the records behind limited K-1 losses
A loss reported on Schedule K-1 is not automatically deductible. Partner-basis, at-risk, passive-activity, and excess-business-loss rules can apply at the owner level in the order described by current instructions. Different records support each limitation, and released losses can depend on later income, basis changes, participation, or disposition facts.
Keep the basis worksheet, Forms 6198 and 8582 when applicable, suspended-loss schedules, debt and guarantee documents, participation records, and prior K-1s. Reconcile the allowed amount to the individual return and preserve the remainder by activity and limitation. For North Carolina, start with the federal result and review current state adjustments rather than assuming every federal basis or loss item carries over identically.
