Missing Depreciation Schedule: Rebuild Your Form 4562 Asset List

Why does Form 4562 show zero depreciation, or the assets vanish, after a new preparer or new software?

Depreciation runs off an asset schedule: each asset's cost, date placed in service, method and depreciation already taken. A new preparer or new software that starts without it has nothing to depreciate, so the year shows zero. Zero is sometimes correct, so find the reason first.

The case is not simple if earlier returns skipped or misstated depreciation, a partnership or corporation must tie its return to a balance sheet, assets were sold or the business changed hands, the numbers will not reconcile, or an IRS notice is open. "Different for you?" at the end of this page covers those cases. Gather:

• Copies of the last three or more returns, with every Form 4562 (not only transcripts)
• Purchase invoices and the bank or card statements that paid them
• Records of anything sold, traded in or scrapped, and mileage logs for vehicles
• The old preparer's depreciation report, or an export from the old software

Do I file Form 4562 every year, and which assets does it list?

No. A return needs Form 4562 only in a year it claims one of these (Form 4562 instructions):

• Depreciation on property placed in service that year
• A section 179 deduction, including a carryover
• Depreciation on a vehicle or other listed property, whatever year it was placed in service
• A deduction for a vehicle reported on a form other than Schedule C
• Amortization that begins that year
• Any depreciation on a corporate return other than Form 1120-S

In other years, earlier assets appear only as one total, on the line for assets placed in service in earlier years (line 17 on the latest published form). The IRS does not ask for asset-by-asset detail for those years, but basis, method and the other inputs must stay in permanent records. Listed property is the exception. A Schedule C filer who claims only the mileage rate or actual vehicle costs without depreciation, and has no other reason to file Form 4562, uses Schedule C, Part IV instead. Any other return that claims the mileage rate, actual vehicle expenses including depreciation, or depreciation on other listed property gives the Part V detail every year (Form 4562 instructions; Schedule C instructions).

What does the depreciation schedule (fixed asset register) need for each asset?

Each asset needs the facts on the Depreciation Worksheet in the Form 4562 instructions. Keep one row per asset so a sale removes the right one. MACRS is the IRS's standard depreciation system. The recovery period is how many years the cost is spread over, and the convention is how the first and last years are prorated.

The IRS worksheet covers federal tax only, so add a column where state rules differ. California, for example, caps its section 179 deduction at $25,000 (FTB Form 3885 instructions). Keep the finished list until the period of limitations ends for the year the asset is disposed of (IRS record-keeping).

How do I get my depreciation schedule from my old preparer or old tax software?

Start with the earlier returns' Form 4562 pages, then the depreciation report the old preparer or software produced, then the IRS.

1. Your own file of filed returns. Pull every Form 4562 and any asset-by-asset report stored with it.
2. The former preparer. Ask in writing for the returns and for the depreciation or fixed asset report from their software. If they are not responding, see taking over books from a former accountant.
3. The old software. Export the fixed asset or depreciation report, and the ledger detail for the asset and accumulated depreciation accounts, before access ends.
4. The IRS. Form 4506 requests a copy of the return with all attachments as filed. It costs $30 per return, can take up to 75 calendar days, and copies of Form 1040-series returns are generally available for 7 years from filing (Form 4506). A corporation or partnership shows the signer's authority by attaching the authorization document.

A transcript is not a photocopy of the return. The IRS offers an individual tax return transcript for the current and three prior tax years (IRS transcript types). Use a transcript for a quick check of line items; order a copy when the Form 4562 pages as filed matter.

What if there is no old depreciation schedule at all?

Rebuild from the documents that prove each purchase, then compare the result with what each return claimed. The first return that showed an asset is the anchor, because it records the class, method and any election.

1. Find every purchase. Start with assets still owned or still in the books; an asset that was fully recovered and is long gone does not need a row. Scan the ledger and the bank and card statements for equipment, vehicles, computers, furniture, tools and improvements. Leave out items expensed as ordinary repairs or under the de minimis safe harbor, an annual election made by a statement with that year's timely original return, so look for the statement (IRS tangible property regulations; see small purchases).
2. Set the date placed in service, the business-use share, the class and the convention. For the date, use when the asset was ready and available for use: delivery if it worked on arrival, otherwise installation. That is not always the first day of use (Publication 946). Use mileage logs for vehicles. For gear a sole proprietor owned before the business began, start from the lower of its value or adjusted basis on the day it entered the business. If no return shows the asset, set the class and convention from the rules in Publication 946: most vehicles and office machinery are 5-year property, office furniture is 7-year, residential rental property is 27.5 years and nonresidential real property is 39 years. For equipment, use the half-year convention unless more than 40% of the year's equipment basis went into service in the last three months, which forces mid-quarter for all of that year's equipment. Figure that test on business cost less any section 179 but before bonus depreciation, and leave out buildings and anything placed in service and disposed of in the same year (Publication 946). Buildings use mid-month.
3. Read each earlier return for elections. The entity that owns the asset makes each one, so a partnership or S corporation elects for itself, not through its owners. A section 179 election is made on Form 4562 with the original return for that year, or with an amended return filed in time. An election out of bonus depreciation covers a whole class of property for that year and is a statement attached to the timely filed return; if the return was timely filed without it, an amended return within 6 months of the due date (extensions not counted) can still make it (Form 4562 instructions). Do not assume either was made because it would have been allowed. Form 3115 cannot be used to make an election (Form 3115 instructions).
4. Work out what was allowable each year and compare it with what each return claimed. Allowable depreciation includes bonus depreciation on qualifying property unless a timely election out was made for that class (Rev. Proc. 2025-23). The bonus rate depends on when the asset was acquired and placed in service, so look it up for each asset's year in section 179, bonus and regular depreciation. An asset where the rate or the election is unclear goes on the list for a professional.

Every gap between the depreciation allowable and the depreciation each return claimed is handled under "What if the rebuilt list shows earlier years were skipped or wrong?" further down.

Why does depreciation I never claimed still lower an asset's basis?

Tax basis falls by the depreciation allowed or allowable, whichever is greater. Allowed depreciation is what was actually deducted and gave a tax benefit. Allowable depreciation is what the owner was entitled to deduct. If allowable depreciation was never claimed, basis still falls by the full allowable amount; if too much was claimed, basis falls by the amount allowed (Publication 946).

This matters at sale. Gain is figured from the reduced basis, and gain on depreciated business equipment is generally taxed as ordinary income up to the depreciation allowed or allowable. Real property follows different rules (Publication 946). Whether the missed deduction can still be claimed is the question in the next section. For a rental, see missed depreciation on a rental property and, for a sale, depreciation recapture when selling a rental.

What if the rebuilt list shows earlier years were skipped or wrong?

The fix is an amended return or a Form 3115 accounting method change, depending on whether the wrong treatment became the business's method. Which row below applies is fact-dependent, and the guidance has exceptions and eligibility limits.

What is the two-year rule?

A business adopts a depreciation method by using a permissible method on its first return for an asset, or by using the same impermissible method on two or more consecutively filed returns (Publication 946). One wrong return can be amended. The same wrong treatment on a second consecutive return makes it a method, and an amended return generally stops being the way to fix it. A math or posting error is different: Publication 946 allows an amended return for one made in any year. Leaving out depreciation entirely counts: the method-change rules cover unclaimed allowable depreciation (Publication 946).

How does a Form 3115 fix work?

The rebuilt list is the calculation. For each asset, compare the depreciation actually deducted with the depreciation allowable before the year of change. The difference is the section 481(a) adjustment; if nothing was deducted, it is the total allowable (Publication 946).

• Negative adjustment (more was allowable): taken in the year of change, and it lowers income.
• Positive adjustment (too much was deducted): generally taken over 4 tax years, or in one year by election if the total is less than $50,000. If the filer is under examination, a positive adjustment is generally taken over 2 tax years instead, subject to the exceptions in the Form 3115 instructions.
• Filing: the original goes with the return for the year of change, filed on time including extensions, and a signed copy goes to the IRS National Office no later than the day the original is filed. Attachments and signatures follow the Form 3115 instructions; the steps are in missed depreciation on a rental property.

Whether a case is an amended return or a method change, how far back it reaches and what the adjustment is can turn on facts the list alone does not show. That is the point to bring in a professional, before anything is filed.

How do cars and other listed property differ?

Cars and other listed property are the assets the IRS asks about every year, and they need business-use records that invoices cannot supply. Listed property includes passenger automobiles weighing 6,000 pounds or less, other transportation property that lends itself to personal use (pickup trucks, SUVs), and property used for entertainment or recreation. Vehicles used for hire and trucks or vans modified so they are unlikely to be used personally are excluded (Form 4562 instructions).

• Business-use test: property used more than 50% in qualified business use can use regular MACRS. At 50% or less it uses straight line, and a later drop to that level can mean recapture, which adds the excess earlier depreciation back to income, figured on Form 4797.
• Records: depreciation and section 179 are not allowed on listed property unless business use is proven with adequate records or sufficient evidence, kept as long as recapture can occur. No daily log is required; a weekly log counts as made at or near the time of use. Reasonable reconstruction is allowed when records were lost to fire, flood or another casualty beyond the owner's control. A log that was never kept is weaker ground: business use must then be shown by a detailed statement and other evidence (Publication 946). Flag those years.
• Standard mileage years: depreciation is built into the rate, and basis falls by a set amount per business mile for each such year, using the yearly table in Publication 463. A car that used the standard mileage rate in its first year of business use and later switches to actual expenses cannot use MACRS; it uses straight line over its remaining estimated life.

For each vehicle and year, the list needs the method (standard mileage or actual), business miles and total miles. To choose between methods, see standard mileage or actual car expenses.

How do I book the depreciation entry so the books tie to the return?

Bring the ledger to the list: fixed assets at cost, accumulated depreciation through last year-end, then the current year's depreciation entry. The ledger needs a fixed asset account, an accumulated depreciation account, a depreciation expense account and a gain or loss on sale account.

1. Opening balances. Make the fixed asset accounts equal the list's total cost and the accumulated depreciation account equal the list's total through last year-end, section 179 and bonus included, posting only the difference. The other side usually goes to equity (retained earnings, partner capital or owner's equity) rather than this year's expense, because it corrects earlier years. If an earlier year's books expensed a purchase that the return capitalized, reverse that expense in the same entry so it is not counted twice. See opening balances after changing accountants and retained earnings that do not match last year's return.
2. The year's depreciation entry. Debit depreciation expense and credit accumulated depreciation for the amount on the return.
3. Disposals. Remove the asset's cost and accumulated depreciation and record the gain or loss.

Then check three totals:

If the books follow a separate book method, keep a tax column and a book column on the list. After a Form 3115 fix, the catch-up enters the return in the year of change, so that year's tie includes the adjustment.

What changes for a partnership, an S corporation or a C corporation?

The asset list belongs to the entity, not the owners, and the return's depreciation line and balance sheet must agree with it.

• Section 179 and basis: a partnership or S corporation lowers the asset's basis by any section 179 it elected, even if an owner cannot use the deduction that year. The part allocated to a trust or estate is the exception (Form 1065 instructions; Form 1120-S instructions).
• Balance sheet: Schedule L on Forms 1065, 1120-S and 1120 is the balance sheet per books, and the instructions say it should agree with the books and records. Small entities that meet the instructions' tests may skip it.
• Fixing a skipped year: the corporation or partnership is the applicant on Form 3115. Where an amended return fits, Rev. Proc. 2025-23 names an amended return or, as applicable, an administrative adjustment request; which one a partnership uses depends on the partnership.

Example

These examples are illustrative. All amounts are in US dollars.

A delivery business whose new software starts with no assets

A single-owner delivery LLC, taxed as a sole proprietorship, bought a $40,000 van (5-year property; assume it is not subject to the passenger-automobile caps) and $6,000 of office equipment (7-year property) in year 1, both before the last quarter. Assume no section 179, bonus depreciation elected out, and the half-year convention. New software starts in year 3 with no assets, so year 3 shows $0.

The fix is to read the year 1 and year 2 Forms 4562, enter both assets with their class, method and convention, and let year 3 continue with the rates in Publication 946, Table A-1:

Accumulated depreciation is $23,126 after year 2 and $31,855 after year 3, leaving $14,145 of the $46,000 cost. Had the year 1 Form 4562 shown the van fully deducted under section 179, a year 3 zero for the van would be correct. Whether the van is listed property depends on the exclusion for vehicles used for hire or other nonpersonal use; if it is, Part V mileage detail is required each year.

A sole proprietor with no copies of old returns

A photographer bought $8,000 of camera gear and $12,000 of shop equipment, both used only in the business, and a $30,000 truck used 80% for business, all in year 1. Invoices and bank statements give each cost and date. The rebuilt list starts like this:

These amounts come before any section 179, bonus depreciation or passenger-automobile cap. Copies of the year 1 and year 2 returns, ordered on Form 4506, show no depreciation on any of the three assets. That is the same treatment on two consecutive returns. Under the two-year rule it may have become a method, which is the kind of case generally fixed with Form 3115 rather than two amended returns; exceptions and eligibility limits are checked before anything is filed. The allowable depreciation for year 1, and so the catch-up, depends on whether bonus depreciation applied and was not elected out. The truck's 80% needs a mileage log; if none exists for year 1, that year goes to a professional.

An S corporation after a new bookkeeper

The ledger shows $50,000 of equipment and $0 of accumulated depreciation, but earlier returns deducted $35,000 of depreciation in total. The rebuilt list confirms $50,000 of cost and $35,000 of depreciation through last year-end.

The opening entry debits retained earnings $35,000 and credits accumulated depreciation $35,000, after checking that none of it was already booked as an expense elsewhere. This year's return claims $5,000, so the year's entry debits depreciation expense and credits accumulated depreciation $5,000. The balance sheet then shows equipment of $50,000 less accumulated depreciation of $40,000, which is what the books would show on Schedule L if the entity completes it. Had the list shown $40,000 allowable through last year-end against $35,000 claimed, the gap would be treated as skipped or wrong depreciation, as described under the heading about skipped or wrong years.

Different for you?

• The asset is a rental property: follow missed depreciation on a rental property; for a sale, see depreciation recapture when selling a rental.
• You are buying equipment this year: see section 179, bonus and regular depreciation.
• Your equity does not match the return, or the old accountant will not respond: see retained earnings that do not match last year's return and taking over books from a former accountant.
• You moved your own equipment into a new LLC, or the LLC became an S corporation: where the asset list starts and at what value depends on how the property moved. See putting personal assets into your LLC and books after an S corporation election.
• You bought the business: whether the old schedule carries over depends on whether the buyer took the assets or the shares. See buying a business.
• The rebuilt list shows depreciation skipped, doubled or wrong in earlier returns; a partnership, S corporation or C corporation return must tie to its balance sheet; assets were sold or the business changed hands; or an IRS notice is open: whether the fix is an amended return or a method change, which years it reaches, and who rebuilds the books to match are decisions for a professional.
