Turning your former home into a rental changes how the IRS treats the property. Rent becomes taxable income, many ownership costs become rental expenses, and the building may become depreciable.
The most important tax decisions begin before your first tenant moves in. You need a defensible value for the property on the conversion date, records of what you originally paid, and receipts for improvements made while it was your home.
If you are still comparing your options, start with our guide on whether you should sell or rent your house. If renting is the plan, this guide explains the federal tax implications of renting out your house.
| Tax issue | What changes after conversion | Record to keep |
|---|---|---|
| Rental income | Rent and certain tenant-paid costs generally become reportable income | Leases, deposits, payment records, and bank statements |
| Operating expenses | Eligible costs may become rental deductions | Invoices, receipts, canceled checks, and mileage records |
| Depreciation | The building may be depreciated once it is ready and available for rent | Conversion date, adjusted basis, fair market value, and land allocation |
| Future sale | Depreciation and rental use can affect taxable gain | Prior tax returns, depreciation schedules, and improvement records |
| Home-sale exclusion | IRC Section 121 may still protect some gain if you meet its tests | Dates you owned, occupied, rented, and sold the home |
What Changes the Day Your Home Becomes a Rental
For tax purposes, the key date is generally when the home is ready and available to rent. It does not always depend on when a tenant signs a lease or pays the first month’s rent.
For example, suppose you move out, complete repairs, and list the home for rent on October 1. A tenant does not move in until December. If the property was ready and genuinely available to tenants on October 1, that may be its placed-in-service date. The IRS explains this rule in Publication 527, Residential Rental Property.
That date affects when depreciation begins and how you divide annual costs between personal and rental use. If you convert the home during the year, expenses such as property taxes and insurance generally must be split between the personal-use period and the rental period. Depreciation and rental insurance are not deductible for the months when the home was held for personal use.
You must also report rental income. This normally includes rent you receive, advance rent, lease-cancellation payments, and some expenses a tenant pays for you. A refundable security deposit generally is not rental income when received if you plan to return it. If you later keep part of it because the tenant broke the lease or caused damage, the amount you keep may become income.
Keep the conversion date in writing. Save the rental listing, dated photographs, repair completion records, insurance change, and correspondence with a leasing agent. Together, those records can show when the home became ready for tenants.
Your New Depreciation Basis
When converting primary residence to rental property, you cannot automatically depreciate the home’s current market value or the amount you originally paid. A special conversion rule applies.
According to IRS Publication 551, Basis of Assets, the depreciation basis of property changed from personal use to rental use is generally the lesser of:
- The property’s fair market value on the conversion date; or
- Its adjusted basis on that date.
Your adjusted basis usually starts with what you paid for the property, including eligible acquisition costs. You then increase it for qualifying capital improvements, such as an addition, a major remodel, or a new roof. Certain credits, insurance payments, casualty deductions, and other adjustments may reduce basis.
Fair market value is the price an informed buyer and seller would agree to when neither is being forced to complete the deal. A professional appraisal made near the conversion date can be helpful. Comparable sales and a property tax assessment may also support an allocation, but an online estimate alone may not provide enough detail if the IRS questions your return.
Land must be separated from the building
Land is not depreciable. After determining the applicable conversion basis, you must allocate it between land and the building. Only the building portion is depreciated.
You may be able to use a qualified appraisal or the relative assessed values shown on a property tax bill to support the allocation. Keep the source and calculation with your permanent tax records.
A simple basis example
Assume your adjusted basis immediately before conversion is $280,000. The home’s fair market value on the conversion date is $320,000. Because adjusted basis is lower, $280,000 is the starting point for the depreciation calculation. You would then remove the portion assigned to land.
If the fair market value were only $250,000, that lower amount would generally control the depreciation calculation. This rule prevents a decline in value during personal use from creating extra rental depreciation.
Residential rental buildings are generally depreciated under the Modified Accelerated Cost Recovery System using the rules described in Publication 527. For most residential rental property under the general depreciation system, the building is depreciated using the straight-line method over 27.5 years. The first and last years are partial years under the applicable convention, so dividing the building basis by 27.5 will not necessarily give the exact first-year deduction.
Deductions That Open Up After Conversion
Before conversion, many routine ownership costs are personal expenses. Once the property is held for rental use, ordinary and necessary rental expenses may be deductible against rental income.
Publication 527 identifies common rental expenses, including:
- Advertising and tenant-placement costs;
- Cleaning and maintenance;
- Insurance for the rental property;
- Legal, accounting, and other professional fees;
- Mortgage interest attributable to the rental period;
- Property management or leasing fees;
- Repairs that keep the property in ordinary operating condition;
- Real estate taxes attributable to the rental period;
- Utilities you pay for the tenant; and
- Depreciation on the building and eligible assets.
A repair and an improvement do not receive the same treatment. Fixing a small leak or replacing a broken component may be a currently deductible repair when it simply keeps the property in normal condition. A project that adds value, extends useful life, or adapts the property to a new use may need to be capitalized and recovered over time.
Timing also matters. Work completed while you are preparing the property for rental may be treated differently depending on whether it is a repair, improvement, or cost of placing the property in service. Do not assume every dollar spent before the listing date is immediately deductible.
Rental deductions are generally reported with rental income on Schedule E. Losses may be limited by the passive activity, at-risk, or other federal tax rules. A deduction can be valid without being fully usable in the current year, so keep records of any amount carried forward.
To see how these deductions fit into your full ownership picture, review the true cost of being a landlord.

The Section 121 Exclusion and the 2-of-5-Year Rule
Converting your home to a rental does not immediately erase the federal home-sale exclusion. Internal Revenue Code Section 121 may allow you to exclude qualifying gain if you meet its ownership and use tests.
In general, you must have owned the home and used it as your main home for at least two years during the five-year period ending on the sale date. The two years do not necessarily have to be continuous. Other requirements apply, including limits involving a home-sale exclusion used for another property.
The maximum exclusion is generally $250,000 for a qualifying individual or $500,000 for certain married couples filing jointly. Meeting the basic ownership and use tests does not guarantee that every dollar of gain will qualify.
How long can you rent the former home?
If you live in the home for at least two years and then move out and rent it, you may continue to satisfy the use test for roughly three years. Once your qualifying residence period falls outside the five-year lookback window, you may no longer meet the full use test unless an exception or reduced exclusion applies.
A rental period after the last date you used the property as your main home and before its sale is generally excluded from the definition of nonqualified use under Section 121. That means renting your former home after moving out does not automatically reduce the otherwise eligible gain on a year-for-year basis.
However, waiting too long can cause you to fail the two-of-five-year use test entirely. Keep the exact move-out and planned sale dates in view rather than relying on calendar years.
When rental use can shrink the exclusion
Certain periods of nonqualified use can reduce the portion of gain eligible for exclusion. This issue commonly appears when a property is first used as a rental and later becomes the owner’s main home. In that situation, part of the gain may be allocated to the earlier rental period and remain taxable even if the owner later satisfies the basic two-year residence test.
The nonqualified-use calculation has exceptions and special rules. It also applies separately from depreciation-related gain. Ask a tax professional to model the sale before you change the property’s use again or choose a sale date.
Depreciation When You Eventually Sell
Depreciation lowers taxable rental income while you own the property, but it also reduces the property’s adjusted basis. A lower basis usually creates a larger gain when you sell.
The portion of gain tied to depreciation deductions generally cannot be excluded under Section 121. This is true for depreciation allowed or allowable after May 6, 1997. In plain English, skipping the deduction usually does not avoid the later tax calculation. The IRS can still require you to reduce basis by depreciation you were entitled to claim.
Landlords often call this result depreciation recapture. For residential rental real estate depreciated using the straight-line method, the federal return may treat the depreciation-related portion as unrecaptured Section 1250 gain, potentially subject to a maximum 25% federal rate. The exact treatment depends on your gain, income, depreciation history, and other facts.
Consider a simplified example. You convert a home, claim depreciation during the rental years, and later sell while still qualifying for a Section 121 exclusion. The exclusion may protect some appreciation, but it generally will not protect the gain attributable to allowable depreciation. Taxable gain above the available exclusion may also remain.
Do not estimate this result from the sale price alone. The calculation can involve selling costs, capital improvements, depreciation, prior personal use, nonqualified use, and the Section 121 limits. Our guide to capital gains tax on real estate explains the larger sale calculation.
Records to Start Keeping Now
The best time to build your tax file is before the first tenant moves in. Years later, it can be difficult to reconstruct what you paid for an old kitchen renovation or prove the home’s value on the conversion date.
Create a permanent property file containing:
- The purchase closing statement and deed;
- Records supporting your original cost basis;
- Receipts, permits, contracts, and photographs for capital improvements;
- A conversion-date appraisal or other fair-market-value evidence;
- The calculation separating land from the building;
- Proof of the placed-in-service date;
- Leases and tenant payment histories;
- Invoices and receipts for repairs, insurance, taxes, utilities, and professional fees;
- Annual Schedule E filings and depreciation schedules;
- Records of personal use after conversion; and
- The dates you bought, occupied, moved out of, rented, and sold the home.
Use separate categories for repairs and improvements. Repairs may affect the current return, while improvements generally affect basis and depreciation over multiple years. Also separate the refundable security deposit from rent so you do not accidentally count the same money as both income and a liability.
A dedicated rental bank account can make this easier, even when federal tax law does not require one for your ownership structure. Avoid mixing grocery purchases, personal mortgage transfers, tenant payments, and rental repairs in one unmarked account.
If you are not ready for software, download a landlord spreadsheet template and update it consistently. Save the supporting receipt as well; a spreadsheet entry by itself does not prove the expense.
A Practical Conversion Checklist
- Choose and document the date the property is ready and available for rent.
- Collect your original closing documents and improvement receipts.
- Establish fair market value near the conversion date.
- Calculate adjusted basis and use the lower value for depreciation.
- Separate the value of the land from the depreciable building.
- Change to appropriate landlord insurance and review local requirements.
- Track rental income, deposits, expenses, and personal use separately.
- Have depreciation calculated correctly from the first year.
- Review the Section 121 timeline before deciding how long to rent.
- Ask a tax professional to review unusual facts, prior credits, mixed use, or a planned sale.
These steps will not remove every tax complication, but they give you the records needed to answer the important questions. They also reduce the chance that a missed receipt or unsupported conversion value creates trouble years later.

Frequently Asked Questions
What happens tax-wise when I convert my primary residence to a rental?
Rental income becomes reportable, eligible rental expenses may become deductible, and depreciation may begin when the property is ready and available for rent. You must divide certain annual expenses between the personal-use and rental periods during the conversion year.
How do I determine the depreciation basis of a converted home?
Under IRS Publication 551, the depreciation basis is generally the lower of the property’s fair market value or adjusted basis on the conversion date. You must then separate land from the building because land cannot be depreciated.
Can I rent my house and still use the Section 121 exclusion?
Possibly. You generally must have owned and used the property as your main home for at least two years during the five years before the sale. Rental use, nonqualified use, depreciation, and prior use of the exclusion can limit the result.
Do I owe depreciation recapture if I qualify for the home-sale exclusion?
You generally cannot use Section 121 to exclude gain attributable to depreciation allowed or allowable for rental use after May 6, 1997. That portion may be treated as unrecaptured Section 1250 gain even when another part of the gain qualifies for exclusion.
Should I get an appraisal before renting out my house?
An appraisal is not automatically required in every conversion, but a qualified appraisal near the conversion date can provide valuable evidence of fair market value and the allocation between land and the building. Discuss the appropriate valuation support with your tax professional.
