What a useful comparison should surface
Compare filing status, dependents, addresses, states, forms, businesses, rentals, carryovers, withholding, estimated payments, and major income categories. The comparison should direct attention; it should not automatically carry a conclusion into the current return.
Drake publicly describes LookBack and LinkBacks as prior-year and source-tracing tools. Firms should confirm how those features appear in their licensed product and pair them with a documented review procedure.
Classify every meaningful variance
Use categories such as expected life event, missing document, data-entry issue, tax-law change, one-time item, or unresolved client question. Classification makes the next action obvious and produces a better review trail than a generic note saying 'different from prior year.'
Set materiality and risk rules at the firm level. A small numerical difference may still be important when it changes eligibility, filing status, basis, or a carryforward.
Prevent blind rollover
Reconfirm facts that affect elections, dependents, residency, business use, and recurring deductions. Prior-year software data can accelerate setup, but the client or source document remains the current-year evidence.
Require a reviewer to clear unexplained disappearances and new items before final approval. The clearance note should state the evidence or client response used.
Turn findings into next year's intake
After filing, feed recurring issuers and known carryovers into next year's organizer while labeling them as expected, not guaranteed. This turns review work into a more precise document request without pre-answering the client.
Retain the comparison and resolution notes according to the firm's record policy and applicable professional requirements.
