Two siblings buy an eight-unit apartment building inside an LLC. The building grosses $180,000 a year, depreciation eats up $48,000, repairs and property taxes eat the rest, and the entity shows a $22,000 paper loss. They expect the loss to flow to their personal returns and offset their W-2 income. It doesn't. The K-1 arrives, the loss lands on a passive activity worksheet, gets suspended, and produces exactly zero tax savings for the year.
This story plays out every spring inside thousands of partnership and S-corporation returns. The form in the middle of it is Form 8825, the worksheet pass-through landlords use to consolidate rental income and expenses before pushing the net number out to owners on Schedule K-1. Understanding how Form 8825 works — and how it interacts with the passive activity rules, real estate professional status, depreciation, and the new Schedule A introduced for the December 2025 revision — is the difference between getting the deduction you earned and watching it disappear into a carryforward column.
What Form 8825 Actually Does
Form 8825 is the rental real estate counterpart to Schedule E. Where an individual landlord reports rents and expenses directly on Schedule E of Form 1040, a partnership filing Form 1065 or an S-corp filing Form 1120-S strips rental real estate activity out of the main return and pushes it onto Form 8825. The bottom line — net rental real estate income or loss from line 21 — then flows back to Schedule K, line 2, where it becomes a separately stated item allocated to each partner or shareholder.
The reason for the split is the passive activity loss rules under Section 469. Rental real estate is presumptively passive regardless of how many hours the owners put in. Congress wanted that passive character to survive the pass-through, so the pass-through return segregates rental activity from operating business activity, and owners apply the passive loss limits at the individual level using their own facts.
A partnership or S-corp must attach Form 8825 if it:
- Owns rental real estate directly (apartment buildings, single-family rentals, commercial leases, vacation rentals with mostly long-term tenants).
- Receives a Schedule K-1 from another partnership, estate, or trust reporting rental real estate activity that flows through to the upper-tier entity.
Hotels, parking lots, and short-term rentals with substantial personal services don't belong on Form 8825 — those are operating businesses, not rental real estate, and they go on the main return.
How the Numbers Flow From Building to Owner
Walk one dollar of rental income through the chain and the mechanics become much easier to internalize:
- The tenant pays rent. It hits the partnership's bank account and posts to the rental income ledger.
- The bookkeeper records expenses. Mortgage interest, property taxes, insurance, repairs, utilities, advertising, management fees, and depreciation each post to property-specific expense accounts.
- Form 8825 consolidates by property. Columns A, B, C, and D on the form let the entity report up to four properties side by side; additional properties spill onto continuation pages. Each property gets its own gross rents (now split between line 2a gross rents and line 2b other rental income in the December 2025 revision), its own expense breakdown, and its own net result.
- Line 21 sums all properties. This is the entity-level net rental real estate income or loss.
- Line 21 lands on Schedule K, line 2. From there, it allocates to partners or shareholders pro rata based on ownership percentages (or special allocations, for partnerships with substantial-economic-effect allocations).
- Each owner receives Schedule K-1. Box 2 of the K-1 reports the partner's or shareholder's share of net rental real estate income or loss.
- The owner reports on Schedule E, Part II. And then immediately runs the figure through Form 8582 to apply the passive activity loss limits before any of it shows up on Form 1040.
Notice what is not on Form 8825: portfolio income (interest, dividends), Section 179 expense, guaranteed payments, gain on sale of rental property (that goes on Form 4797 and flows separately through K-1), and non-rental business activity. Each of these has its own line on the main partnership or S-corp return.
The Depreciation Trap That Eats Returns
Depreciation is the single largest deduction on most Form 8825 filings, and it is also where most amateur preparers either lose money or generate an audit-magnet return.
The mechanics are straightforward: residential rental real estate depreciates straight-line over 27.5 years, commercial rental over 39 years, land improvements over 15 years, and personal property used in the rental (appliances, carpeting, furniture) over 5 or 7 years. Land never depreciates. The entity claims depreciation on Form 4562 and reports the total on line 14 of Form 8825.
Three failure modes show up in audits over and over:
- Forgetting depreciation entirely. Self-prepared entity returns sometimes skip depreciation because the cash didn't move. The IRS doesn't care. Under the "allowed or allowable" rule, when the property is eventually sold the recapture is calculated as if depreciation had been claimed every year. Skipping it just gives up the deduction without escaping the recapture.
- Depreciating land. A purchase price gets allocated between land and building based on the most defensible source — usually the county assessor's ratio, sometimes an appraisal. Land sitting in the depreciable base inflates current deductions and creates an exposure the IRS finds quickly.
- Failing to capitalize improvements. A new roof, an HVAC replacement, a parking lot resurfacing — these are not repairs. They are improvements that must be capitalized and depreciated. The tangible property regulations and the de minimis safe harbor (up to $2,500 per invoice or item, or $5,000 for entities with applicable financial statements) draw the line.
When the entity placed property in service during the year or claimed depreciation on listed property, Form 4562 must be attached. The total depreciation amount flows to Form 8825 line 14, and improvements added mid-year start their depreciation clock on the date placed in service, not the date of purchase.
The Passive Activity Rules That Quietly Kill Losses
Here is the rule that surprises new pass-through landlords: rental real estate is automatically passive under Section 469, regardless of whether the partners spend ten hours a year or ten thousand. That passive character survives the K-1 and reaches the owner's Form 1040, where it bumps into Form 8582 and the passive activity loss (PAL) rules.
Passive losses can offset only passive income. They cannot reduce W-2 wages, active business income, interest, dividends, or capital gains. A partner whose K-1 box 2 shows a $40,000 loss but who has no other passive income gets exactly zero current-year deduction. The loss isn't gone — it becomes a suspended PAL that carries forward indefinitely and unlocks when (a) the partner generates passive income, (b) the partner disposes of the entire activity in a fully taxable transaction, or (c) the partner's situation changes in a way that converts the loss to non-passive.
Two escape hatches exist:
The $25,000 special allowance. Active participants in rental real estate — meaning the partner makes management decisions like approving tenants, setting rent, and approving capital improvements — can deduct up to $25,000 of rental losses against non-passive income. The allowance phases out between $100,000 and $150,000 of modified AGI, so by $150,000 it is fully gone. Limited partners and most S-corp shareholders don't qualify for active participation; general partners and members of an LLC who participate in management generally do.
Real estate professional status (REPS). This is the bigger lever. A taxpayer who qualifies as a real estate professional under Section 469(c)(7) escapes the per-se passive treatment of rental real estate and can deduct losses against any income — provided they also materially participate in each rental activity. Qualification requires three things:
- More than 50% of personal services for the year performed in real property trades or businesses in which the taxpayer materially participates.
- More than 750 hours of services performed in real property trades or businesses during the year.
- Material participation in each rental activity, applied separately unless the taxpayer makes the Section 469(c)(7)(A) election to aggregate all rental real estate as a single activity.
The 750 hours and the more-than-50% test apply per taxpayer, not per couple. Real property trades and businesses include development, construction, acquisition, conversion, rental, operation, management, leasing, and brokerage. A full-time W-2 employee almost always fails the more-than-50% test because their other job consumes too many hours, which is why REPS frequently shows up on the spouse's side of a joint return.
Documentation matters. Courts have rejected REPS claims based on "approximately" or round-numbered after-the-fact estimates. Calendars, appointment books, contemporaneous logs, and even reasonable summaries reconstructed from emails and texts have been accepted; ballpark guesses have not.
The New Schedule A for 2025 and Larger Entities
For tax years beginning in 2025, the IRS revised Form 8825 and added Schedule A (Form 8825) for partnerships and S-corps required to file Schedule M-3. Schedule M-3 generally applies to entities with $10 million or more in total assets at year-end, along with a handful of other triggering thresholds.
For those filers, the old "Other expenses" line on Form 8825 — historically attached as a free-form taxpayer schedule — gets replaced by twenty named expense categories on Schedule A, one Schedule A per property. The categories cover items like asset management fees, building maintenance, common area charges, contract services, prepayment penalties, Section 481(a) adjustments, and similar specifics. Column (c) is also new and required only for Schedule M-3 filers — it asks for property type codes and other supplemental information.
The December 2025 revision of Form 8825 itself also splits line 2 into 2a (gross rents) and 2b (other rental income such as parking and laundry), reflecting the IRS's appetite for cleaner segmentation between core rent and ancillary income streams.
If the entity is below the Schedule M-3 threshold — which covers the vast majority of small partnerships and S-corp landlords — none of this changes anything. Smaller filers keep using the existing Form 8825 expense lines without the new Schedule A.
How to Allocate Income, Loss, and Depreciation to Owners
The default rule in a partnership is allocation based on partnership interest. A 60/40 partnership reports 60% of Form 8825 net result to one partner and 40% to the other on their K-1s. S-corps are stricter: allocations must follow stock ownership pro rata, with no special allocations permitted.
Partnerships, however, can use special allocations if they have substantial economic effect under Section 704(b). A common pattern in real estate joint ventures is a preferred return waterfall — Partner A puts up 90% of the capital and gets 90% of depreciation and losses until a stated hurdle is met, then the split shifts. Substantial economic effect requires capital account maintenance under the 704(b) regulations, qualified income offset language in the operating agreement, and an actual economic deal that matches the tax allocation. Half-baked special allocations get reallocated by the IRS to the partners' interests in the partnership, which usually disappoints whichever partner thought the agreement saved them tax.
A few related allocation items that touch Form 8825:
- Section 754 elections step up the inside basis of property when a partnership interest is sold or a partner dies, which affects the depreciation deduction allocated to the specific partner — increasing the deduction the new partner sees on Schedule K-1 without changing what other partners see.
- At-risk rules under Section 465 apply at the partner level before passive activity rules. Partners can only deduct losses up to their amount at risk in the activity, which generally means cash and recourse debt contributions, plus their share of qualified nonrecourse financing in the case of real estate. Excess losses suspend at the at-risk level.
- Basis limits under Section 704(d) or 1366 apply even before at-risk rules. A partner whose adjusted basis in the partnership interest is zero cannot deduct rental losses, period — they suspend at the basis level.
The cascade — basis, then at-risk, then passive, then the rest — means owners can hit three different walls before a Form 8825 loss touches their 1040.
Common Mistakes That Trigger IRS Scrutiny
Five errors show up disproportionately in IRS examinations of Form 8825:
1. Mixing personal use without proper accounting. If a partner or shareholder uses the rental property personally for more than 14 days or 10% of the rental days, whichever is greater, the property converts to a mixed-use property and the loss deduction gets capped at rental income. The personal-use days must be tracked and reported, and expenses get allocated by ratio.
2. Reporting non-rental activity on Form 8825. Hotels and motels, B&Bs with substantial personal services, short-term rentals with average customer stays of seven days or fewer, and parking facilities with attendants are operating businesses, not rentals. They go on the main partnership or S-corp return, not Form 8825. The distinction matters because operating business income/loss is non-passive and follows different rules entirely.
3. Not attaching Form 4562 when required. If property was placed in service during the year, or any listed property (vehicles, etc.) is involved, Form 4562 is required. Missing it generates a correspondence letter from the IRS.
4. Failing to disclose grouping elections. Section 1.469-4 lets taxpayers group rental and non-rental activities for material participation purposes if they form an "appropriate economic unit." The grouping must be disclosed in the year of election. Retroactive groupings invented during an audit do not generally hold up.
5. Allocating expenses inconsistently across years. Auditors compare year-over-year on the same property. Wild swings in maintenance, advertising, or "other" expenses without an explanation invite questions. Consistency wins.
Bookkeeping Habits That Make Form 8825 Filings Easier
Reading the line items on Form 8825 backwards, you can design the entity's chart of accounts to feed the form directly. The line items the form expects, per property:
- Gross rents (2a) and other rental income (2b)
- Advertising, auto and travel, cleaning and maintenance, commissions, insurance, legal and other professional fees, interest, repairs, taxes, utilities, wages and salaries, depreciation, and other
A clean chart of accounts uses one account per line item per property, so that a year-end report runs straight into the Form 8825 columns without a reclassification project in April. Separate sub-accounts for capital improvements (which capitalize and depreciate) versus repairs (which expense currently) save hours of cleanup.
Three habits compound over time:
- Track basis from day one. Closing costs, title insurance, transfer taxes, and improvements all roll into basis. Reconstructing this five years later from a stack of HUD-1s is painful.
- Log time contemporaneously. If anyone is pursuing REPS, the calendar entries are the proof. After-the-fact reconstruction is much weaker.
- Reconcile bank accounts monthly. Rental real estate is full of timing items — security deposits, prepaid rents, late fees, mid-month closings — that grow into reconciliation horror stories if left for year-end.
The entity-level bookkeeping is also where audit defense lives. Receipts, invoices, lease agreements, depreciation schedules, and improvement logs need to be preserved at the partnership or S-corp, not scattered across individual partner files.
A Worked Example to Pin It Down
Consider an LLC taxed as a partnership owned 70/30 by Anna and Ben. The LLC owns two residential rental buildings:
- Property A: $120,000 gross rents, $35,000 depreciation, $55,000 other expenses → $30,000 net income
- Property B: $90,000 gross rents, $42,000 depreciation, $80,000 other expenses → $32,000 net loss
Form 8825 totals: $210,000 gross rents, $77,000 depreciation, $135,000 other expenses, net loss of $2,000. That $2,000 net loss flows to Schedule K, line 2, and gets allocated $1,400 to Anna (70%) and $600 to Ben (30%) on their K-1s in box 2.
Anna is a full-time software engineer with $180,000 of W-2 income. She doesn't qualify as a real estate professional, and her modified AGI is over $150,000, so the $25,000 special allowance phases out completely. Her $1,400 loss suspends as a passive activity loss and carries forward.
Ben is a licensed real estate broker who spent over 1,400 hours managing properties and brokering deals during the year — well over both the 750-hour and 50% tests. He elected to aggregate his rental activities and materially participates in both. His $600 loss is non-passive and deducts against his other ordinary income with no limit.
Same K-1, same activity, completely different outcomes — because the passive activity analysis runs at the owner level, not the entity level.
Keep Your Pass-Through Books Audit-Ready From Day One
Pass-through rental real estate is one of the most paperwork-heavy areas of the tax code. Between Form 8825, Form 4562, Form 8582, Form 8995, Section 704(b) capital accounts, basis tracking, at-risk worksheets, and per-property records, the difference between a smooth filing and a six-figure adjustment is usually bookkeeping discipline.
