Behind on Rental Property Books: How to Catch Up and File

Rebuild the oldest missing year first, one property at a time, from bank and card statements, the closing statement, loan statements and tax bills. Sort every deposit and payment, rebuild basis and depreciation, then file; a multi-member LLC's Form 1065 goes before its owners' returns. Each year starts from the one before, so one mistake changes every later year.

Where do I start when my rental books are years behind?

Start with the oldest missing year and work forward, one property at a time. Two problems are mixed together: paperwork (books and records that are missing or wrong) and filing (returns never filed). The IRS says to file every past due return, even if you cannot pay in full. How many missing years the IRS expects is covered in catching up on unfiled returns.

Order matters because each year starts from the one before it: basis (what you paid for the property, adjusted each year), depreciation taken and any suspended passive loss (a rental loss the rules do not let you use yet, carried to a later year) all roll forward. The steps:

  1. List every property, who holds title (you, an LLC, a trust, co-owners) and the dates it was rented.
  2. Find out which returns the IRS has, using transcripts.
  3. Gather the documents for the oldest missing year.
  4. Rebuild that year property by property, file it, then carry its ending balances into the next year.

Gather for each property: bank and card statements, the closing statement, Form 1098 or lender statements, tax bills, leases and rent records, property manager statements, and your last filed return and IRS transcripts. Ask each bank, card issuer and lender for statements you no longer have; how far back they can supply them varies. The size of the job is properties times entities times accounts times months, so each added year, entity or unreconciled account adds work.

The case is not simple when two or more years are missing, there is more than one property, an LLC or trust holds title, a former bookkeeper left books you cannot trust, an IRS letter has arrived, or a lender, court or new preparer is waiting on a date. See "Different for you?" at the end.

Which returns are missing: my Form 1040s, an LLC's Form 1065, or both?

The return generally depends on who holds title to the property, not on who collected the rent.

Who holds the rentalReturn that reports itWhere the rental goes
You alone, or you and a spouseForm 1040Schedule E, Part I, one column per property (instructions)
A domestic LLC with one member and no electionThe owner's Form 1040Schedule E, Part I; the LLC is generally not a separate entity for federal tax (instructions)
A domestic LLC with two or more members and no electionForm 1065 and a Schedule K-1 for each memberForm 8825 on the 1065; each member's share goes on Schedule E, Part II of their own Form 1040 (instructions)
A trustA revocable living trust is treated as a grantor-type trust, not a separate taxable entity, so its owner reports its rental items, and the trust may be able to skip a separate Form 1041 under the optional filing methods; other trusts may need Form 1041See the Form 1041 instructions

A domestic partnership must file Form 1065 unless it neither received income nor had deductions, and an LLC with at least two members and no election is classified as a partnership (Form 1065 instructions). An LLC that elected corporate treatment files a corporate return, which this page does not cover. An LLC owned only by a married couple as community property may be treated either as a disregarded entity or as a partnership, and the IRS accepts the couple's treatment (Revenue Procedure 2002-69); changing that treatment counts as a conversion of the entity. An LLC's classification also follows its members: a one-member LLC that adds a second owner becomes a partnership from that date, and a partnership ends when one person buys all the other interests, so one LLC can have Schedule E years and Form 1065 years (Revenue Rulings 99-5 and 99-6). List the date each owner joined or left.

File the partnership's returns first, oldest year first: each partner's personal return needs the K-1. For an LLC that never filed, see unfiled business returns. For co-owners who hold title directly, see Schedule E or partnership return. For the partners' capital accounts and K-1s, see rebuilding partnership capital accounts. Money moving between an LLC, a trust and you personally is usually a loan, a contribution or a distribution, not rental income or expense: see books for an LLC per rental and mixed funds.

How do I get my old returns and the income forms the IRS already has?

Order transcripts for every missing year and for the last year you filed. They show what the IRS holds, the first check on your rebuild (IRS transcript types).

What you needWhere it comes fromHow far back
Forms the IRS received from payers, including Forms 1098 and 1099Wage and income transcriptCurrent and nine prior years
Payments and changes on your accountAccount transcriptCurrent and nine prior years online; older with Form 4506-T
Your return as originally filedReturn transcriptCurrent and three prior years
A full copy of a filed returnForm 4506, fee $30 per returnGenerally 7 years from filing
Proof that no return was processedVerification of non-filing letterPrior three years; older with Form 4506-T

The wage and income transcript shows only forms filed with the IRS, which may not be every form issued to you. Online it is limited to about 85 documents; past that, the IRS directs you to Form 4506-T. A non-filing letter does not say whether you were required to file. A property manager reports rent paid over to an owner on Form 1099-MISC when it meets the form's reporting threshold (instructions); match any such form to the manager's statements and your deposits.

Your last filed return holds the numbers the rebuild starts from: depreciation to date, any suspended passive loss and each property's basis. If an old preparer or software holds them, ask now; see rebuilding a missing depreciation schedule.

What can I rebuild from bank statements, and what must I get from others?

Bank and card statements rebuild what moved and when. They do not show what a payment was for or what a property cost. A statement can prove payment if it shows the payee, amount and date (and the check number for a check), but proof of payment alone does not establish a deduction; keep the invoice or receipt (Publication 583).

ItemWhere it comes from
Rent receivedBank deposits matched to leases and a rent ledger; property manager statements; any Form 1099-MISC
Mortgage interestThe lender's Form 1098, sent when an individual borrower pays $600 or more of interest on one mortgage (Publication 527). A lender need not send one when an LLC, partnership or trust is the borrower, so the interest then comes from the lender's statements (Form 1098 instructions)
Property tax and insuranceTax bills, insurance statements, the lender's escrow statement
Purchase price and closing costsThe closing statement (Publication 583 lists real estate closing statements as asset records)
Land versus buildingThe property tax assessment from the county assessor
Repairs and improvementsInvoices, contractor statements, card statements
Depreciation and carryovers to dateThe last filed return and its worksheets

The title or escrow company, the lender and the county assessor can supply copies; the IRS names them in its guidance on reconstructing records after a disaster, which is written for casualty losses but points to the same offices (IRS). For the closing statement, see entering it in the books. To work from bank statements alone, see rebuilding books from bank statements.

What if the books exist but a former bookkeeper left them wrong?

Do not start from the old totals. Reconcile every bank, card and loan account to its statements, month by month, then check how the old books handled:

  • uncategorized or suspense balances;
  • deposits booked as rent that were security deposits, loan proceeds or transfers between your own accounts;
  • mortgage principal booked as an expense;
  • improvements booked as repairs;
  • personal spending mixed in;
  • depreciation never booked.

Compare each year's rent total with the wage and income transcript, the filed return and the leases. A figure that no statement or document supports is one to question, not to carry forward. If a filed return used wrong figures, see amending for income left off past returns.

How do I sort each deposit and payment into rent, deposits, loan principal, interest, repairs, improvements and personal?

Sort every line before totaling anything. A deposit, a loan payment or a personal payment in the wrong place changes the year's income (Publication 527).

Deposit or paymentHow it is treated
Rent, including rent paid in advanceIncome when received under the cash method; advance rent is income in the year received, whatever period it covers
Rent a manager collects for youGross rent when the manager receives it, because an agent's receipt is yours; the manager's fees and costs are separate expenses, and the net payout is not rent (Publication 538)
An expense your tenant pays for youRental income; deduct the expense if it is a deductible rental expense
Security deposit you plan to returnNot income when received; income in the year you keep part of it
Deposit used as the last month's rentAdvance rent: income when received
Mortgage payment: interestDeductible rental expense
Mortgage payment: principalNot deductible; it reduces the loan
Points on the closing statementPrepaid interest: generally deducted over the term of the loan, not in the year paid; points left when the loan ends may be deductible then (Publication 527)
Loan or refinance proceedsA loan, not income; interest on the part not used for the rental generally is not deductible as rental interest
Repair or maintenanceDeductible unless it must be capitalized
Improvement (a betterment, restoration or adaptation)Capitalize and depreciate
Personal spending and transfers between your own accountsNot rental income or expense; keep out of the rental ledger

A mortgage payment that includes escrow is interest, principal and a deposit. The deposit is not an expense: use the escrow statement to record property tax and insurance when the lender pays them; for taxes, only what the lender actually paid is deductible (Publication 530). For each bucket, see security deposits, repair or improvement, property manager statements and, if rental and personal money share an account, mixed funds.

What do I do about repairs paid in cash or with no receipt?

Assemble every other record that shows who was paid, how much, when and for what, and write dated notes now. The IRS says that when a cash payment has no receipt, you should make an adequate explanation in your records at the time of payment (Publication 583). For past years that moment has passed, so date anything you write as written today and never make a document look older than it is.

Whether a cost with no record at all can be estimated depends on the facts, and an unsupported cost may be disallowed on examination. What counts as support is covered in rental property records and receipts.

How do I rebuild each property's basis, land share and depreciation?

For each property bought for rental, start from cost, take out land, start depreciation on the date the property was ready for rent, and reduce basis by the depreciation allowed or allowable. A residential rental building is generally depreciated straight-line over 27.5 years under the general depreciation system, with a mid-month convention, and the first year counts only the months in service (Publication 527).

StepRule
Purchase costThe price plus settlement costs that belong to basis: title insurance, legal fees, recording fees, surveys, transfer taxes. Loan costs such as points and the lender's appraisal fee do not
A former home, an inheritance or a giftA former home: the lesser of adjusted basis or fair market value on the date it became a rental; keep that date and a record of the value (Publication 527). Inherited property generally starts at its value at the date of death; a gift follows rules based on the donor's basis (Publication 551)
Land shareLand is not depreciable. Divide cost between land and building by fair market value; if you are not certain of those, use the assessed values on the property tax bill
Start dateWhen the property is ready and available for rent, even before the first tenant
ImprovementsAdd each with its own date and depreciate it separately; appliances, carpeting and furniture are 5-year property, apart from the building (Publication 527)
Adjusted basisCost plus improvements, minus depreciation you took or could have taken. If you never took any, basis is reduced by the full amount you could have taken (Publication 551)

If earlier years skipped depreciation, see missed depreciation on a rental.

How do passive losses and depreciation carry from one year to the next, and why does one wrong year change the rest?

Each year's ending balances are the next year's opening balances, so a figure wrong in one year is wrong in every year after it.

What carries forwardWhat it sets next yearWhere to find it
Adjusted basis of each propertyDepreciation, and any gain or loss on a later saleThe last filed return's depreciation records
Depreciation allowed or allowableLowers basis whether or not it was claimedThe same records
Suspended passive lossCarried forward until allowed against passive income, the rental loss allowance described below, or a fully taxable sale of the whole interest to an unrelated party (instructions)Form 8582 and its worksheets
A loss disallowed by the at-risk rulesTreated as a deduction of the same activity next year (Publication 527)Form 6198
A partner's basis in the partnership interestLimits the partnership loss the partner can deduct each year; a loss over basis is carried forward until basis allows itThe partner's own records, figured with the worksheet in the Partner's Instructions for Schedule K-1 (Schedule E instructions)

Rental losses are generally passive, except for certain real estate professionals. A landlord who actively participated, which means owning at least 10% and making management decisions such as approving tenants and repairs, may deduct up to $25,000 of rental loss against other income. The allowance phases out between $100,000 and $150,000 of modified adjusted gross income for a single or joint filer, so a higher-income landlord's loss is suspended instead (Publication 527). A married person filing separately has no allowance if they lived with their spouse at any time during the year, and has $12,500 (phasing out between $50,000 and $75,000) if they lived apart all year (Publication 501, Publication 527). A partnership keeps no record of a partner's suspended losses; the partner tracks them (Form 8582 instructions).

A missed depreciation year, a wrong land share or a repair booked as an improvement does not stay in its own year. For years never filed, file them with the right balances. For a year already filed, an amended return may correct a wrong depreciation amount, but the same wrong treatment, even none, on two or more consecutively filed returns becomes your method, and changing a method generally takes Form 3115 (Publication 527, Publication 946); see missed depreciation on a rental. That is why the rebuild runs oldest year first.

What will filing late cost, and what if I am owed a refund?

Late filing and late payment each add a percentage of the unpaid tax for each month or part of a month, up to 25% and 25% (filing, payment), and interest runs on unpaid tax and on penalties. Personal-return detail is in catching up on unfiled returns. Because the penalties are percentages of unpaid tax, a year in which withholding and payments covered the tax may have no percentage penalty.

A late Form 1065 is different: a set amount per partner for each month or part of a month, up to 12 months, whether or not tax is owed. The amount is indexed each year; the base rate for each return due date is in the table on the failure to file penalty page. For relief, see the late partnership return penalty and small-partnership relief guides.

For a year never filed, the IRS can assess tax at any time; filing your own return starts the usual three-year assessment limit, which is six years if the return leaves out more than 25% of the gross income it shows (IRS, 26 U.S.C. 6501). If withholding or estimated payments exceeded a year's tax, the refund generally must be claimed by filing within three years of that return's due date, plus the length of any filing extension you had; a Presidentially declared disaster can add time (IRS). The IRS holds a current refund while an earlier return is past due (IRS).

What if an IRS letter, a lender, a divorce or a new preparer is waiting on a date?

Read the date on the letter or the lender's request first. The work order stays the same, oldest year first, and only the pace changes; a legal deadline, such as a Tax Court petition date, is met on its own date.

Who is waitingWhat they needWhat must come first
The IRSA filed return, sent to the address on the letterRead the response date. After a substitute return, a CP3219N notice of deficiency gives 90 days from its date (150 days if it is addressed outside the US) to petition the Tax Court. A past due return answers the notice but does not extend the petition date, and no extension is available for the notice (CP3219N, past due returns)
A lenderCopies of filed returns, which lenders require for a purchase or refinanceRebuilt books, then filed returns. The IRS says an accurately completed past due return takes approximately 6 weeks to process (IRS); a return transcript usually meets a mortgage lender's needs (IRS)
A divorce or courtReturns for specific years, each with a filing statusThe joint-or-separate choice, before filing: spouses on a joint return may be held responsible, jointly and individually, for its tax, interest and penalties, and after the due date you cannot switch a filed joint return to separate returns (Publication 501); see responsibility on a joint return. Filing separately also changes the rental loss allowance, described above
A new preparerTotals per property, basis and depreciation to date, the suspended passive lossThe year-by-year rebuild above

When the stakes are a refinance, a court date or an IRS deadline, the order of years and entities and what is realistic by the date are judgment calls. See "Different for you?" below.

Do I need software to catch up, or is a spreadsheet enough?

In most cases the law does not require any specific kind of records; any system that clearly shows your income and expenses will do (Publication 583). A catch-up needs one ledger per property that ties to the Schedule E lines, keeps repairs and improvements apart, and carries basis and depreciation forward. For the trade-offs, see spreadsheet or software for rentals.

How do I keep the books current once they are caught up?

Close each month, and keep what proves each entry:

  1. Record every deposit and payment monthly, by property, using the buckets above.
  2. Reconcile each account to its statement so a missing or duplicate entry shows up while it is small (Publication 583).
  3. Book a repair or improvement correctly when it is paid and keep the invoice; you need the cost of improvements to depreciate and to sell (Publication 527).
  4. Keep rental money in accounts used for the rental: a separate bank account for each rental.
  5. Keep property records until the limits run for the year you dispose of the property, and indefinitely for any year never filed (IRS).

Example

These examples are illustrative; amounts are in US dollars.

Two condos, three years unfiled

A landlord owns two condos in their own name and has not filed for three years, called Year 1 to Year 3. Rent is about $36,000 a year in total, cash expenses (interest, property tax, insurance, repairs) about $28,000, and depreciation about $10,000, worked out from each closing statement and land share. Assume both condos were rented all year in all three years, the landlord has no income from other passive activities, no suspended loss from an earlier year and no at-risk limit, and nothing is sold. Modified adjusted gross income is at least $150,000, so the rental loss allowance is zero (see the carry-forward section) and each year's loss is suspended: held and carried to a later year instead of deducted.

Year 1Year 2Year 3
Rent$36,000$36,000$36,000
Cash expenses$28,000$28,000$28,000
Depreciation$10,000$10,000$10,000
Loss for the year$(2,000)$(2,000)$(2,000)
Suspended loss carried forward$2,000$4,000$6,000

The landlord rebuilds Year 1 first, files a Schedule E with a column for each condo, then starts Year 2 from Year 1's ending basis and suspended loss. Had Year 1 left out depreciation, it would show $8,000 of income instead of a $2,000 loss, and Years 2 and 3 would start from the wrong basis and the wrong carryover.

A refinance waits on two years of returns

A landlord plans to refinance a $400,000 loan on a rental. The lender wants the last two years of returns. Both are unfiled; the year before them was filed. The lender's date sets the schedule, not the order: the older of the two years is rebuilt first, from the last filed return's basis and carryovers, then filed, then the newer year. The IRS says processing takes approximately 6 weeks, so the schedule counts back from the lender's date by that time plus the time to rebuild each year. If the date is closer than that, the lender needs to be asked what it will accept.

Two partners and a rental LLC

Two people own a rental LLC 50-50, with no entity election. No Form 1065 or K-1s were filed for two years. The LLC files a Form 1065 for each year, oldest first, and each partner's own return takes its rental figures from the K-1. The late-filing penalty runs per partner per month: 2 partners times up to 12 months is up to 24 partner-months for each year, at that year's amount, unless relief applies. The partners' personal returns for those years wait on the K-1s.
