Most filers struggle with the same four tasks: identifying the right assets, reconstructing the old and new methods, calculating the Section 481(a) adjustment, and keeping the filing consistent with the tax return. For Australian businesses with U.S. tax obligations, an unfamiliar system adds another layer of difficulty.
This guide covers what Schedule E captures, how to complete it, how the adjustment works with examples, and how to file. All figures are in U.S. dollars.
Key Takeaways
- Schedule E ties a depreciation or amortisation method change to specific assets and calculations.
- Form 3115 Schedule E is not Schedule E of Form 1040.
- Accurate placed-in-service dates, recovery periods and conventions make a filing defensible.
- Current IRS instructions and revenue procedures control eligibility and filing mechanics.
What Form 3115 Schedule E Is and When It Applies
Form 3115 requests a change in an overall accounting method or in the accounting treatment of a particular item. Schedule E is required when the change involves depreciation or amortisation.
What Schedule E is designed to capture
Schedule E identifies the affected property and gives the factual basis for the new method. It asks for:
- Asset type and placed-in-service year
- Use, credits or basis adjustments
- Present and proposed method, recovery period and convention
It is easy to confuse with the other Schedule E. Form 1040 Schedule E reports rental real estate, royalty, partnership, S corporation, estate and trust income and loss. Form 3115 Schedule E reports nothing of the sort. It supports a method change request.
When Schedule E is generally relevant
Typical triggers include:
- Missed or impermissible depreciation claimed over several returns
- An incorrect recovery period or convention
- A look-back cost segregation study on an asset already in service
Under Treas. Reg. 1.446-1, a treatment repeated on two or more consecutive returns is generally an adopted method. Mathematical or posting errors are not method changes and may be fixed by amended return.
A correction to the placed-in-service date generally is not a method change either, and it produces no Section 481 adjustment.
The IRS gives a published example. A taxpayer placed a copier in service in August 2003 and used seven-year recovery, 200% declining balance and the half-year convention on two returns. The correct period was five years, and the regulation treats the correction as a method change with a Section 481 adjustment.
Why classification matters before completing the form
Your facts decide whether the change is automatic or non-automatic, whether Schedule E is required, and whether an adjustment applies.
Rev. Proc. 2015-13 (as modified) sets the general procedures. Rev. Proc. 2025-23 (as modified) holds the automatic-change list, and its section 6.01 covers qualifying impermissible-to-permissible depreciation changes. Older change-number lists are not current authority, so check the live instructions before relying on any number.
How to Complete Schedule E: Information and Supporting Attachments
What to gather first
For each affected asset, collect:
- Description, ownership and business or income-producing use
- Placed-in-service date and original basis
- Improvements, credits, grants and basis adjustments
- Depreciation claimed and depreciation that should have been claimed
- Old versus proposed recovery period, method, convention and elections
Completing the asset-level information
The December 2022 form asks for the following:
| Schedule E item | What to provide |
|---|---|
| Line 1 | Whether depreciation uses the class-life asset depreciation range system |
| Line 2 | Whether depreciation must be capitalised, such as under section 263A |
| Line 3 | Depreciation, amortisation, expensing or disposition elections made |
| Line 4 | Property description, placed-in-service year, use, credits and basis adjustments |
| Lines 5-6 | Present treatment and facts supporting the proposed change |
| Line 7 | Present and proposed Code provisions, class, method, life and convention, plus special depreciation |
Line labels can change between versions, so work from the latest form. Where assets differ in dates, classes, methods or conventions, attach a schedule rather than cramming them into the printed lines.
Preparing the supporting statement
The statement should cover:
- Property description and its use
- Prior method and proposed permissible method
- Legal authority for the change
- Why the taxpayer qualifies for the requested procedure
Part IV line 26 also needs the Section 481(a) amount, whether it increases or decreases income, and a summary of the computation and methodology.
Reconciling with the rest of the filing
Asset details must agree with:
- The Section 481(a) workpaper
- Form 4562 and the depreciation schedules
- The general ledger and the return
Form 4562 calculates the deduction, while Form 3115 requests the method change. A reviewer should be able to trace every Schedule E asset from acquisition records through the calculation to the reported adjustment.
How the Section 481(a) Adjustment Works: Examples and Key Insights
Understanding the adjustment
IRC 481(a) prevents amounts from being duplicated or omitted solely because of a method change. Publication 946 describes the depreciation adjustment as total depreciation actually deducted minus total allowable depreciation, both measured before the year of change.
Under Rev. Proc. 2015-13, the general timing rules are:
| Adjustment | General treatment |
|---|---|
| Negative (reduces income) | Entire amount in year of change |
| Positive (increases income) | Ratably over four years |
| Positive under $50,000 | One-year election available |
| Positive requested under examination | Generally two years, with exceptions |
Procedural exceptions exist, so confirm the current rules for your change.
Example 1: one asset with missed depreciation
Suppose a business placed a $100,000 five-year asset in service and claimed nothing on two filed returns. Using Table A-1 percentages, allowable depreciation was 20.00% in year one and 32.00% in year two, or $20,000 and $32,000. That is $52,000 allowable against $0 claimed.
The adjustment is -$52,000, a negative adjustment deducted in the year of change. Schedule E describes the asset, its placed-in-service year and the move from no depreciation to MACRS.
The supporting statement shows the computation. Year-three depreciation (19.20%) belongs in the year of change, not the adjustment.
Missing depreciation never preserves higher basis. Under IRC 1016(a)(2), basis is reduced by at least the allowable amount.
Example 2: several assets or a wrong recovery period
Take a building purchase followed by a look-back cost segregation study. Land stays non-depreciable. Components reclassified to five-year property need their own placed-in-service dates, classes and calculations.
The IRS Cost Segregation guide says changing an adopted method after a later study generally requires Form 3115 and Section 481(a), not amended returns.
Several inputs can change the result materially:
- Bonus depreciation: 100% for qualified property acquired and placed in service after 19 January 2025 (P.L. 119-21), unless elected out. Earlier 2025 acquisitions generally get 40%
- Section 179 limits: $2,500,000 for 2025, with phase-out starting at $4,000,000
- Credits, basis adjustments and prior claims
The ordering is Section 179, then special depreciation, then regular MACRS.
Common calculation safeguards
- Reconcile tax depreciation to book records, prior returns, asset ledgers and disposals
- Treat a missed election, wrong placed-in-service date or arithmetic slip as a possible non-method issue
How the Mid-Month Convention Affects Schedule E Calculations
Under IRC 168(d), residential rental property (27.5 years), nonresidential real property (39 years), and railroad grading or tunnel bores (50 years) use the mid-month convention. Property placed in service or disposed of during a month is treated as placed or disposed of at the midpoint of that month.
Contrast with other conventions
The half-year convention is the general default. Mid-quarter generally applies when more than 40% of the relevant property's aggregate basis is placed in service in the last three months. Real property is excluded from that test.
Mini-example
Using Publication 946 (2025) tables, July placement gives these first-year and second-year percentages:
| Property | Convention | Year 1 | Year 2 |
|---|---|---|---|
| Five-year (Table A-1) | Half-year | 20.00% | 32.00% |
| Residential rental (A-6) | Mid-month | 1.667% | 3.636% |
| Nonresidential real (A-7a) | Mid-month | 1.175% | 2.564% |
On a $500,000 nonresidential building placed in service in July, Year 1 depreciation is about $5,875. Applying the wrong convention or table changes every pre-change year, and with it the adjustment.
Do not pick a convention from the acquisition date or book treatment alone. Match it to the property type and tax classification.
Filing Form 3115 Correctly: Timing, E-Filing, and Review Checklist
Filing mechanics
For automatic changes, attach the original to the timely filed return (including extensions) for the year of change. A separate signed duplicate goes to the IRS no earlier than the first day of the year of change and no later than the date the original is filed.
The December 2022 instructions give the duplicate address as Internal Revenue Service, Ogden, UT 84201, Attn: M/S 6111. Confirm it on the IRS filing page before sending.
The instructions recognise an e-filed Form 3115, but the signed duplicate is still required separately. Non-automatic requests are generally filed during the tax year of change and carry a $13,225 user fee under Rev. Proc. 2026-1. Automatic requests have no fee.
Common mistakes to avoid
- Confusing the two Schedule E forms
- Omitting asset-level descriptions
- Using an outdated form version
- Leaving out the legal-basis statement
- Reporting a Section 481(a) amount that does not reconcile to depreciation schedules
Final review checklist
- Eligibility, including same-item changes in the prior five years
- Automatic or non-automatic status
- Examination status, with a copy to the agent if applicable
- Year-of-change timing and required duplicates

Frequently Asked Questions
What is Form 3115 used for?
It requests or reports a change in accounting method, including certain depreciation, amortisation, inventory or income-recognition changes.
Can Form 3115 be filed with my tax return or e-filed?
The original attaches to a timely filed return, and a signed duplicate goes separately. E-filing is recognised, but confirm current IRS and software rules.
What does the mid-month convention mean?
Qualifying real property is treated as placed in service or disposed of at the middle of the month for depreciation purposes.
What information goes on Schedule E of Form 3115?
It covers the property, its use, placed-in-service year, present and proposed methods, and supporting calculations or statements.
Is Schedule E of Form 3115 the same as Schedule E on Form 1040?
No. Form 3115 Schedule E supports a depreciation method change. Form 1040 Schedule E reports rental, royalty, partnership, estate or trust income.
When should I use Form 3115 instead of amending a return?
Use Form 3115 for an adopted method. Amend for one-year mathematical or posting errors and cases where no method was adopted.
