Most tax advisory engagements begin with a forward look. The advisor evaluates the client’s current situation, identifies upcoming opportunities, and develops a plan for the year ahead. The approach is reasonable but structurally incomplete; it ignores the years already behind, where missed opportunities have already accumulated and where structural problems have already taken their toll.

AE Tax Advisors operates a different model. Every client engagement at the Billings, Montana tax advisory firm begins with a proprietary 3-Year Tax Lookback, a structured backward review of the client’s three most recent tax returns conducted by the firm’s team of IRS Enrolled Agents and licensed CPAs. The lookback is not optional and not separately priced; it is built into the foundation of the engagement.

The reasoning is structural. Most business owners and high-income professionals are sitting on tax recovery opportunities they don’t know exist. The Internal Revenue Code allows recovery of many missed deductions, unused credits, and structural inefficiencies through specific procedures, but only if the recovery is identified, documented, and executed correctly. Forward planning without the backward review leaves the recovery opportunities on the table.

The 3-Year Tax Lookback at AE Tax Advisors covers several specific dimensions.

The first dimension is missed deductions. The lookback reviews each prior return for deductions that should have been claimed but weren’t. Common examples include vehicle expenses incorrectly classified, home office expenses missed entirely, business-related travel that was treated as personal, equipment purchases that qualified for Section 179 but were depreciated under standard methods, retirement plan contributions that weren’t optimized for the prior year, and educational expenses that qualified for deduction or credit but were missed.

The second dimension is incorrectly classified expenses. Many expenses produce dramatically different tax outcomes depending on classification. The lookback identifies expenses that were classified suboptimally, a property improvement treated as a repair (or vice versa), a business expense classified as personal (or vice versa), an equipment purchase treated as supplies expense (or vice versa), and quantifies the tax difference between the correct and the incorrect treatment.

The third dimension is unused credits. The tax code includes specific credits that many business owners and high-income professionals are eligible for but never claim. The Research and Development credit. The Work Opportunity Tax Credit. Energy efficiency

credits. Retirement plan startup credits for small businesses. Various state-specific credits. The lookback evaluates each credit against the client’s actual operations and identifies the credits that should have been claimed in prior years.

The fourth dimension is structural inefficiencies. The lookback evaluates the broader structural setup of the client’s tax position, entity structure, retirement plan design, depreciation methods, multi-state apportionment, equity compensation handling, and identifies whether the structural elements have been optimal across the prior period. Where structural problems are identified, the lookback recommends corrections going forward and identifies any catch-up positioning that should be executed.

Once the missed opportunities are identified, AE Tax Advisors executes the recovery through specific procedures.

Form 1040-X is used to file amended individual returns where the recovery requires amending prior-year filings. The three-year statute of limitations from the original filing date applies, which means most missed deductions and credits from the prior three years are recoverable through amendment.

Form 1120-X serves the same function for amended corporate returns where the entity is a C-Corporation.

Form 3115 is used for changes in accounting method, particularly for depreciation method changes including cost segregation catch-up. The Form 3115 procedure has the significant advantage of allowing the entire catch-up adjustment to be claimed in the current year without amending prior returns.

The recovery mechanisms have specific procedural requirements that AE Tax Advisors handles. Statute of limitations analysis. Documentation requirements. Specific filing procedures. The firm’s team, IRS Enrolled Agents and licensed CPAs led by Christina Nortman, has the technical expertise to execute the recovery procedures correctly and integrate the recovery with the forward-looking strategic tax plan that follows.

The combination, backward recovery plus forward strategy, produces results that pure forward-looking advisory cannot match. Clients arriving at AE Tax Advisors often discover that they have unclaimed tax recovery sitting in their prior returns that exceeds the firm’s annual $7,800 advisory engagement fee several times over. The lookback essentially funds the engagement from recoveries the client did not know existed.

The 3-Year Tax Lookback is also an audit preparedness review. The lookback identifies positions on prior returns that may be vulnerable to challenge and either corrects them or strengthens the supporting documentation. By the end of the lookback process, the client’s tax position is significantly more defensible than it was at engagement start.

For business owners and high-income professionals who have not had a structured review

of their prior tax returns, the AE Tax Advisors 3-Year Tax Lookback is one of the more valuable initial conversations available. The recovery is real. The work is built into the engagement. And the team has the specific expertise to execute the procedures correctly.
