Tax Planning Before April: A Practical Action Calendar

By AE Tax Advisors Team | Published November 6, 2026

This original AE Tax Advisors guide accompanies Tax Planning Should Happen Before April, Not During It.

Start with a forecast you can actually use

Tax preparation reports what happened. Tax planning helps determine what to do while decisions are still available. A useful forecast combines year-to-date income, expected remaining income, payroll, investment activity and deductions supported by records. It should show both estimated liability and expected payments, because a lower balance due can result from higher withholding without any reduction in total tax.

For a business owner, begin with reconciled books and separate company profit from owner distributions. For an employee, gather recent pay statements, bonus expectations, equity compensation details and household income. A plan based on last year alone can miss a business acquisition, a property sale or a significant change in compensation.

Use the middle of the year to make structural decisions

Entity classification, owner compensation and retirement plan design deserve time for analysis and implementation. Review the full cost of a proposed change, including payroll, state taxes, administration and future exit consequences. An LLC or corporate election does not create a deduction simply because paperwork was filed.

Ask for a written decision record: the proposed action, eligibility requirements, expected tax effect, cash required, responsible person and deadline. Some elections and contributions have deadlines after year-end, while other actions must occur during the tax year. The calendar should identify the actual rule for each item.

Make year-end a completion checkpoint

Before December ends, confirm that planned actions occurred and collect the evidence. An equipment purchase may require the asset to be ready and available for business use before depreciation begins. A retirement strategy may require coordination with a plan administrator and payroll provider. Business reimbursements require a valid policy and substantiation.

Avoid spending a dollar solely to obtain a deduction worth a fraction of that dollar. Compare the after-tax cost with the business benefit and cash reserves. Tax savings should support a sound financial decision.

Use filing season to reconcile the plan

When information returns arrive, compare them with the forecast. Reconcile estimated payments, withholding, carryforwards and entity returns before finalizing the individual return. Document differences so the next forecast starts from accurate information.

Bring your prior returns, current financials, pay statements and a list of upcoming transactions to an AE Tax Advisors discovery call. The goal is a practical implementation sequence with evidence and deadlines, rather than a list of strategies that never reaches the return.
