The April filing is accurate. That is a true thing and also a limited thing.
Your CPA receives the documents in February. The 1099s, the K-1s, the brokerage statements. They organize what arrived. They report what occurred. They file correctly. If there was a loss to harvest, it arrived in the documents. If there was a gain to offset, it arrived in the documents. If there was an opportunity that existed in October and closed in December, it arrived nowhere, because nobody captured it.
Tax preparation is a reporting job. Tax planning is a different job.
What reporting looks like
A return preparer’s year looks like this: February and March, documents arrive. April, the return is filed. The rest of the year, other things. What happened in the portfolio in September, what the insurance agent did in November, what the business generated in Q3: the CPA learns about all of it when the forms arrive in February.
This is not incompetence. It is how the engagement is structured. A return preparer is hired to file accurately. They do. The result is an accurate picture of what happened. Not a picture of what could have happened if someone had acted earlier.
What planning looks like
Tax planning is forward-looking. It requires knowing about decisions before they become taxable events.
A Roth conversion made in November, when income is lower than projected, reduces the balance in a pre-tax account before required distributions begin. That decision has to be made in November, with knowledge of that year’s income picture. A return preparer who receives documents in February cannot make that decision in November.
Loss harvesting that offsets a significant capital gain has to happen before the gain is recognized, with enough coordination to sequence the two correctly. A return preparer who receives the 1099 in February cannot sequence what happened in October and December.
An installment sale that spreads gain across two or three tax years has to be structured before the sale closes. A return preparer who receives the closing documents in February cannot restructure a completed transaction.
The decisions that reduce taxes are made before the tax year ends. The documents that record those decisions arrive months later. There is a structural lag between when planning happens and when a return preparer sees any of it.
Where the gap lives
The CPA’s structural limitation is not a question of qualification. Many CPAs are excellent planners. The limitation is that planning requires real-time visibility into what the other advisors are doing, and the traditional engagement model does not provide it.
Your wealth manager rebalances in September. They execute. Your insurance agent recommends a policy change in October. They complete it. Your CPA learns what both of them did in February.
If the September rebalancing generated a capital gain, and the October policy change generated additional taxable income, and there was a loss harvesting opportunity in the portfolio that went untouched because nobody flagged it: the CPA reports the combined result accurately in April.
The window closed in October. The documents arrived in February. The return was filed in April.
The question worth asking
Most people with a CPA they trust have accurate returns. They do not have tax planning. They have a record of what happened to them financially, competently organized and correctly filed. That record tells them what they owed. It does not tell them what they could have paid instead.
Whether any of that applies to your situation requires knowing what your advisors actually communicated to each other last year, and when.
