MHP Insurance Costs: What’s Deductible and What Isn’t

Insurance is one of the largest non-debt expenses a mobile home park owner carries. Between property and casualty coverage, general liability, flood, umbrella policies, and workers’ compensation, annual premiums can run well into five figures — and for larger parks, six.

Yet most MHP owners don’t have a clear picture of which premiums belong on their tax return, how to categorize them correctly, and what the IRS actually requires. Getting this wrong doesn’t just cost you money at filing time — it can create problems with lenders reviewing your operating statement.

This guide breaks down every major insurance type an MHP owner carries, what the IRS says about deductibility, and how to present insurance costs cleanly on your financials.

The IRS Standard: Ordinary and Necessary

The foundational rule for any business deduction is IRC §162 — the expense must be “ordinary and necessary” in carrying on your trade or business. For insurance, this means two things: (1) the coverage must be commonly carried by businesses in your industry, and (2) it must be appropriate and helpful for your specific MHP operation.

Every insurance policy you carry on your park — assuming it protects your business operations — meets this standard. The IRS does not require you to prove the coverage was “worth it.” You just need to show it was a legitimate business insurance cost paid or accrued in the tax year.

For cash-basis taxpayers, you deduct insurance premiums in the year paid. For accrual-basis taxpayers, you deduct them in the year the coverage period applies. Prepaid premiums that extend more than 12 months beyond the payment date are generally not fully deductible in the year paid — they must be spread over the coverage period.

Types of MHP Insurance and Their Deductibility

General Liability Insurance

This covers bodily injury and property damage claims arising from your park operations — a resident slips on a common area, a visitor is injured near the mailbox kiosk, a contractor damages a neighboring property. General liability is 100% deductible as an ordinary business expense.

This is not optional coverage for any operating MHP, and the IRS will never question its necessity. Deduct it in full.

Property and Casualty Insurance

Property and casualty coverage protects your physical assets — the park-owned homes (POHs), the clubhouse, the office, common area structures, and sometimes the utility infrastructure depending on the policy. All of this is deductible.

An important distinction: property insurance on a POH that you own and rent or lease to a resident is a legitimate business expense because the POH is a business asset. The fact that someone lives in it doesn’t change the character of the deduction — you own the property, you bear the risk of loss, and you’re running a business.

Flood Insurance

If your park sits in or near a FEMA flood zone, flood insurance is both required by most lenders and deductible as a business expense. Even if it’s not required, flood coverage on an MHP in a vulnerable area is ordinary and necessary — parks have significant infrastructure below grade (utility lines, septic, drainage) that flood damage can devastate.

Deduct flood insurance premiums in full. Keep the policy declarations page in your records.

Umbrella and Excess Liability Insurance

An umbrella policy extends your liability limits beyond what your general liability and property policies cover. MHP owners frequently carry umbrella coverage because the exposure profile — dozens or hundreds of residents, common areas, aging infrastructure — is significant.

Umbrella premiums are fully deductible as a business expense. There is no IRS limitation on the amount of liability coverage you can insure or deduct.

Workers’ Compensation Insurance

If you have employees — maintenance staff, park managers, office personnel — workers’ compensation coverage is required in most states and fully deductible as a business expense. Even in states where coverage for sole proprietors or very small employers is not mandated, if you carry it, it’s deductible.

If you use independent contractors exclusively and have no employees, you may not need workers’ comp. But be careful: misclassifying an employee as a contractor creates far bigger problems than the cost of coverage.

Directors and Officers (D&O) Insurance

If your MHP is owned through a multi-member LLC or partnership with active partners, a D&O or management liability policy protects the individuals making decisions on behalf of the entity. This is particularly relevant when you have outside investors or limited partners.

D&O premiums are deductible as ordinary business expenses when the coverage protects the business entity and its officers in the conduct of business affairs.

What Is NOT Deductible

Personal Life Insurance on the Owner (When Business Is Not the Beneficiary)

This is the most common mistake MHP owners make. Life insurance on your own life, where your spouse or personal estate is the beneficiary, is not a business deduction. It doesn’t matter that you’re the key person operating the park — if the business is not the named beneficiary, it’s personal insurance.

Key-person life insurance — where the business entity or a buy-sell agreement is the beneficiary — follows different rules. In most cases, it is still not deductible under IRC §264(a)(1) when the business is directly or indirectly the beneficiary. This is a nuanced area you should review with a tax professional before assuming deductibility.

Self-Insured Reserves

Some MHP owners set aside funds in a “reserve account” to self-insure against losses. Unless you’ve actually paid a loss or purchased coverage from a licensed insurer, the funded reserve is not deductible. The IRS requires that the insurance expense be paid or accrued — a reserve you’ve set aside but haven’t spent is neither.

If you experience an actual uninsured loss, you may be able to deduct the casualty loss under IRC §165. But the reserve itself is not a deduction.

Insurance on Non-Business Assets

If you own a vehicle, property, or other asset personally (not inside your MHP entity) and you deduct the insurance through the park, that’s a problem. The deduction must match the entity that owns the asset.

Insurance Documentation Requirements

The IRS expects you to substantiate every deduction. For insurance, that means keeping the following for each policy year:

• Declarations page showing coverage type, limits, and premium
• Proof of payment (bank statement, cancelled check, or credit card record)
• The policy itself, or at minimum the summary of coverage
• Evidence that the coverage applies to the tax year in question

This documentation also serves a second purpose: when lenders underwrite a refinance or a buyer conducts due diligence, they will want to see your trailing insurance costs to normalize your NOI. Clean records make that process faster.

How to Present Insurance on MHP Financial Statements

When presenting financials to a lender or potential buyer, separate your insurance line items. A single “Insurance — $47,000” line raises questions. A breakdown that clearly shows property, liability, flood, and umbrella gives underwriters confidence in your numbers.

Insurance and Your MHP Tax Return

On Schedule E (for pass-through entities) or Form 1065 (partnership), insurance premiums are reported as a deductible expense on the line labeled “Insurance (other than health).” If you operate through an S-Corp, the same applies on Form 1120-S.

Health insurance for employees and owners is reported separately and follows different rules — don’t lump it with your property and liability premiums.

If you pay insurance for POHs under a blanket property policy that also covers personal property (furniture, appliances), you may want to allocate the premium between the business portion and any personal use. For most MHP operators, all coverage is 100% business, making this a non-issue.
