CPA of Denver · Tax planning guide
Tax preparation reports a completed tax year. Tax planning considers decisions while there is still time to act, and a tax projection estimates the result using current information. A household may need all three, but they should be clearly identified in the engagement.
Tax Planning vs. Tax Preparation: What’s the Difference?
On a small screen, scroll the table sideways to view all columns.
| Work | Main question | Typical inputs |
|---|---|---|
| Return preparation | What must be reported for the completed year? | Final tax forms, statements and supporting records. |
| Tax projection | What might the current-year tax and remaining payment look like? | Year-to-date information, expected income and payments, and stated assumptions. |
| Tax planning | Which available decisions should we evaluate before acting? | A projection, goals, deadlines and the facts for each scenario. |
What Return Preparation Covers
Preparation brings together the records needed to complete the applicable federal and state returns. It includes the review and filing steps agreed in the engagement. Finding a planning issue while preparing a return does not mean that year-round projections or additional meetings were included in the original fee.
What a Year-End Projection Can Help You Evaluate
A projection can combine both spouses’ wages, expected bonuses, investment activity and known equity events. The review compares expected tax with withholding and estimated payments, identifies missing information and establishes which assumptions could change. Federal and Colorado work should be identified separately in the scope.
Income tax is paid during the year through withholding or estimated payments; a balance due and an underpayment penalty are different questions. See the IRS underpayment guidance. The IRS Tax Withholding Estimator is an available federal resource; a household projection may require additional review of investment, equity and state information.
When to Revisit the Plan
Consider a discussion when compensation changes, a large investment transaction is contemplated, stock awards vest or options may be exercised, a move affects state filings, or another material change occurs. Provide enough lead time to obtain records and evaluate choices before their relevant deadlines.
A Household Example
Suppose both spouses have W-2 income, one expects a bonus and stock vest, and the household anticipates selling investments. Preparation will later report the completed year’s events. A current-year projection brings the expected amounts and withholding together. Planning evaluates the decisions still available using that projection and the household’s goals. The events and assumptions need updating if compensation or transactions change.

Frequently Asked Questions
Does preparing a tax return include proactive planning?
Not automatically. Preparation reports the completed year; projections and planning meetings should be expressly included in the engagement or separately scoped.
Can W-2 employees benefit from tax planning?
Yes. Two earners, variable bonuses, investment activity, equity compensation and changing deductions can create questions that are useful to review before year end.
Does a projection guarantee what I will owe?
No. A projection uses available information and assumptions. Changes in income, transactions, records or applicable rules can change the final result.
