MHP Tax Planning for the Year You Buy: First-Year Strategies

The year you acquire a mobile home park is the single highest-leverage year for tax planning in the entire ownership lifecycle. The decisions made in the acquisition year — some of which must be made before closing or before the first return is filed — set the foundation for every year that follows. Decisions that were not made correctly in year one often cannot be corrected without cost and complexity. Decisions made well in year one compound into years of tax efficiency.

This guide covers the five most important decisions MHP owners face in their acquisition year, what can and cannot be fixed retroactively, and why the year-one relationship with your MHP accountant is worth more than any other year of service.

Why the Acquisition Year Is Different

In every subsequent year of MHP ownership, tax planning is largely optimization within an established structure. You are managing depreciation on a set schedule, allocating income and loss within a framework set by your operating agreement, and making annual elections within the parameters established at acquisition.

In the acquisition year, the structure itself is being established. Entity selection, depreciation methodology, passive activity classification, and bonus depreciation elections are all made for the first time — and the choices you make control the entire forward picture. Getting these decisions right before they become permanent is the opportunity that the acquisition year presents.

Decision 1: Confirm the Correct Entity Held the Acquisition

Before closing, you should have confirmed with your MHP accountant that the purchasing entity is the right structure for your tax goals. The entity choice — single-member LLC (disregarded entity), multi-member LLC (partnership), S-Corp, or other structure — determines how income and loss are taxed, whether the passive activity rules apply and at what level, and how the eventual sale is structured.

Once closing occurs in a particular entity, the entity structure is established. Restructuring after closing — contributing the park to a different entity, changing the tax classification of the entity — has potential tax consequences, including recognition events that could trigger gain. This is not impossible to change, but it is far more expensive and complex than making the right decision before closing.

If you are acquiring with partners, the partnership agreement must also be reviewed before closing for the tax provisions that matter — capital accounts, special allocations, the 754 election, and guaranteed payment treatment. As discussed in our guide on MHP partnership agreement tax provisions, these provisions control your tax outcome for the life of the partnership.

Decision 2: Complete a Cost Segregation Study Before the First Return Is Filed

The ideal time to commission a cost segregation study is immediately after closing, while the property inspection is fresh and the acquisition-year return has not yet been filed. Having the study complete before the first return is the cleanest path — the asset classifications flow directly into the depreciation schedule and there is no need for an accounting method change.

If the first return is filed without cost segregation and you later want to reclassify assets, the correction requires IRS Form 3115 (Change in Accounting Method) and a Section 481(a) catch-up adjustment — valid, but adds complexity and professional fees. Filing with cost segregation from day one is simpler, cheaper overall, and produces the same or better tax result.

The cost segregation study identifies assets that qualify as 5-year personal property, 7-year property, and 15-year land improvements rather than the standard 39-year non-residential real property classification. The amount reclassified — and the resulting additional depreciation — depends on the park’s mix of improvements, infrastructure, and POH units.

Decision 3: Make the Bonus Depreciation Election — or Affirmatively Opt Out

Bonus depreciation under IRC Section 168(k) allows qualifying property — the 5-year and 15-year property identified by cost segregation — to be deducted immediately in the year placed in service, rather than depreciated over the MACRS life. This is an extremely powerful first-year deduction.

Bonus depreciation is automatic — you do not need to elect into it. You need to affirmatively elect out if you do not want it. The question to model before filing is: does taking maximum bonus depreciation in year one produce the best after-tax outcome, or is there a scenario where spreading depreciation over several years is more valuable?

Relevant considerations include: whether you have enough passive income (or other income) to absorb the deduction currently; whether the deduction creates a large net operating loss (NOL) that will carry forward; whether you are in a state that does not conform to federal bonus depreciation (if so, the state tax benefit is reduced); and whether maximizing year-one deductions reduces basis below zero for some partners, creating suspended loss issues.

In most MHP acquisitions where the operator has material participation or passive income to absorb losses, maximizing bonus depreciation produces the best net present value outcome. But “most” is not “all,” and the election should be modeled with actual numbers for your specific situation — not defaulted to without analysis.

Decision 4: Establish the Depreciation Schedule With Correct POH Classification

Park-owned homes (POH) are generally classified as personal property for depreciation purposes — typically 5-year or 7-year MACRS depending on the specific asset and the period the home was placed in service. This is a shorter life than real property components of the park, and the correct classification produces more accelerated depreciation on POH units.

However, POH classification must be established correctly from the first year. If POH units are misclassified as part of the 39-year real property structure, the error understates depreciation and overstates taxable income. Correcting it later requires a Form 3115. Getting it right in year one is the no-cost option.

Beyond the POH classification, the entire depreciation schedule for the park — land versus improvements, infrastructure versus structures, personal property versus real property — should be reviewed at acquisition with your MHP accountant. The cost segregation study provides the asset-level analysis; your accountant converts it into the depreciation schedule on the return.

Decision 5: Determine Passive vs. Non-Passive Status From Day One

How the park’s income and loss flow to your individual tax return depends on whether you materially participate in the park’s operations or whether your investment is passive. This determination — active versus passive — must be made for the first year and applied consistently going forward.

Material participation is determined by a seven-factor test under IRC Section 469 and the related Treasury Regulations. The most commonly used tests are: you participated in the activity for more than 500 hours during the year, or your participation was substantially all of the participation of all individuals in the activity. For MHP operators who are actively involved in day-to-day operations, material participation is often achievable.

The real estate professional exception — which requires 750 hours in real property trades or businesses with real estate as your primary activity — is the path to making MHP losses non-passive and usable against ordinary income. But this status cannot be applied retroactively to prior years and must be documented with contemporaneous time logs in the first year it is claimed.

For MHP operators who also have W-2 income, the passive activity question is especially important. Read our detailed guide on MHP taxes for operators with W-2 income to understand how the passive activity wall affects operators who also work other jobs.

What You Can Fix Retroactively — and What You Cannot

Why Acquisition-Year CPA Involvement Is Worth More Than Any Other Year

Many MHP operators engage an accountant after the first year’s return is due — when they have already filed, already made (or missed) critical elections, and already established depreciation schedules that may not be optimal. By that point, the accountant is filing returns within a framework that was set, often by default, without professional guidance.

Engaging an MHP-specific accountant before closing — or at minimum before the first return is filed — is the highest-value professional relationship in the ownership lifecycle. The incremental cost of acquisition-year planning is small relative to the additional depreciation that is correctly captured, the entity structures that are optimized from day one, and the elections that are made intentionally rather than by default.

The tax savings from a well-executed acquisition-year plan — correct cost segregation, properly elected bonus depreciation, correctly established passive activity status — typically exceed the cost of the planning engagement many times over in the first year alone, before the compounding benefit of correct structures in subsequent years is considered.
