CPA TCP Tax Planning Simulations: Organize Facts by Year (2027 Prep)

Organize a tax-planning simulation by the period and status of each fact before using it in a calculation. A forecast, a completed transaction and a legal effective date can all appear in the same file while supporting different conclusions.

Our original teaching file follows a projected customer payment into a later recorded receipt, then keeps an entirely separate invented law change on its own date track. Keep both records. No actual exam exhibit, taxpayer file or enacted amendment is reproduced here.

Keep the forecast visible when the record changes

Fictional Crescent Map Studio is an individual proprietor's calendar-year service business, validly using the cash method throughout 2026 and 2027. Assume ordinary taxable service receipts, no special recognition method and no agent or other recipient receiving this payment earlier on the proprietor's behalf. We hold the stated receipt rules constant for this educational model, without verifying future law.

An invented planning note dated October 12, 2026 forecasts a $5,000 customer payment on December 28, 2026, while a separate invented completion record later states that the actual amount is $4,700, received January 4, 2027. The full model expressly supplies no actual or constructive receipt before that January date.

Preserve the October estimate. It can explain why an earlier plan expected 2026 cash, but it cannot establish a 2026 receipt after the completed facts differ. All later dates are author-created future events for the lesson, not observed business history.

Record the date that supports the recognition rule

Paragraph (a) of 26 CFR 1.451-1 in the eCFR ties cash-method service income to actual or constructive receipt. Under the model's explicit absence of either kind of receipt in 2026, this particular $4,700 payment belongs in the 2027 income track under the held-constant rules.

That is one payment's treatment. We have not calculated total business income, deductions, self-employment tax or an owner's tax bill. The $300 difference between forecast and completed amount is a forecast variance, not an assumed deductible loss or a tax saving.

The original year-by-year fact map (CSV) preserves the October planning date, the expected December payment date and the supplied January receipt date. Each has its own field. Replacing all three with the document's most recent date would remove the evidence needed to explain why the original plan changed.

Change availability before changing the year

A January bank entry alone would leave an important question open: was the money already available in December? 26 CFR 1.451-2 in the eCFR covers income credited, set apart or otherwise available to draw, with a boundary for substantial limitations or restrictions. Physical possession is therefore not the only fact that can matter.

Here, availability is settled. In a real file, a statement showing only the deposit date would not settle every constructive-receipt question, and a forecast would supply even less evidence. Record availability and restrictions before choosing a year.

If those facts change, rebuild the analysis. A different case with unrestricted availability in December cannot inherit our January conclusion merely because the learner postponed depositing a payment. This article supplies no specific payment instrument or restriction facts from which to decide that alternative.

Give legal dates a separate track

Now consider a wholly invented federal tax amendment, unrelated to Crescent's receipt, with enactment on May 12, 2026 and an effective date of January 1, 2027. We invent no substantive deduction, rate or eligibility provision, so the dates support only a timing demonstration.

Record enactment separately. The effective date identifies the assumed start of the hypothetical change, while neither date establishes what a particular taxpayer qualifies for or what will appear on a future exam.

A draft planning note saying a change is expected remains a projection, even after someone files it in the 2027 folder. Actual work requires the real source and applicable provisions, including any transition rules that could change the result.

Check exam eligibility against the right policy category

The AICPA tested-law policy treats federal tax changes separately from accounting and auditing pronouncements, using for tax the calendar quarter beginning six months after the later effective or enactment date. The invented law-date comparison (CSV) applies that category only to our invented tax amendment.

January 1, 2027 is later than May 12, 2026. Six calendar months after January 1 is July 1, 2027. July starts a quarter. Under this general policy demonstration, the invented change would first become eligible on July 1, rather than becoming eligible merely because its effective date falls in January.

A March 10, 2027 study target is before that modeled date, while an August 10 target is after it. Both targets are invented, not booked appointments. Being after the date establishes general eligibility in this hypothetical calculation, without verifying detailed TCP task coverage or an actual tested-law announcement.

Check the tax category. Applying the accounting-pronouncement formula to every tax change would replace the policy we actually checked. The landing page lists a separate H.R. 1 announcement, but its instructions were not inspected here and no H.R. 1 cutoff is asserted.

Carry the source status into the next study session

The blank fact-and-authority record (CSV) separates the period, document date, fact status, accounting method, receipt evidence, authority version and exam target. Qualified review remains blank. Add a source location beside the year assignment so you can find the passage that supports it later.

For Crescent, the completed receipt replaces the forecast in the recognition analysis while the forecast remains part of the planning history. For the invented amendment, the legal and exam dates stay on their own track. Neither example supplies a real tax-planning recommendation.

When a year assignment remains uncertain, identify the missing fact or authority before recalculating. Qualified tax review is required before publication, along with matching TCP hub coverage, detailed future alignment and fresh current-source checks. The editorial reviewers' scores do not supply that professional approval.

2027 preparation edition. All Crescent transactions, forecasts, later completion records, study targets and amendment dates are author-created fiction. Model holds stated receipt rules constant, not a verification of future law. Public AICPA and eCFR HTML checked October 12, 2026. The eCFR identifies its text as authoritative but unofficial, Title 26 current through October 8, 2026. No actual H.R. 1 instructions, detailed future tasks, taxpayer liability or professional tax approval verified. Qualified tax review, matching hub and fresh release checks required. No linked form, PDF, worksheet or assessment inspected.
