Schedule E (Form 1040): Supplemental Income and Loss – 2010 Tax Year Guide
What the Form Is For
Schedule E (Form 1040) is the IRS form used to report supplemental income or loss—money you earn beyond your regular wages. If you own rental property, receive royalties, or have income from a partnership, S corporation, estate, or trust, this is the form to use.
Specifically, Schedule E covers income and losses from:
- Rental real estate (houses, apartments, commercial buildings, etc.)
- Royalties (copyrights, patents, oil, gas, and mineral rights)
- Partnerships and S corporations (your share of pass-through business income)
- Estates and trusts (income you receive as a beneficiary)
- REMICs (Real Estate Mortgage Investment Conduits)
Schedule E has multiple parts:
- Part I – Rental properties and royalties
- Part II – Partnerships and S corporations
- Parts III–IV – Estates, trusts, and REMICs
You attach Schedule E to your Form 1040. The net income or loss flows through to your overall taxable income.
Think of Schedule E as the place to report passive or investment income—the money you make from properties you own or ventures you invest in, not from active work.
When You’d Use It (Including Late or Amended Filings)
Standard Filing
For the 2010 tax year, Schedule E was due with Form 1040 by April 18, 2011 (April 15 was a federal holiday that year). Farmers and fishermen could file by March 1, 2011 to avoid estimated tax penalties.
Late Filing
If you missed the deadline, file as soon as possible. The IRS charges a 5% per month penalty (up to 25%) for late filing, plus interest. Filing—even without full payment—reduces penalties.
Amended Returns
You must file Form 1040-X if you need to correct Schedule E after filing. Common reasons include:
- Forgetting to report rental income
- Missing deductible expenses
- Receiving a corrected Schedule K-1
- Incorrectly applying passive activity loss or at-risk rules
Attach your corrected Schedule E and explain the changes. You generally have three years from your original filing to amend and claim a refund.
Key Rules for the 2010 Tax Year
Section 179 Expensing
You could immediately deduct up to $500,000 of qualifying business property instead of depreciating it. For 2010, this applied to tangible property (like appliances or equipment in rentals). The deduction phased out after $2,000,000 in purchases.
Bonus Depreciation
Property placed in service during 2010 qualified for 50% bonus depreciation, allowing faster write-offs.
Passive Activity Loss Rules
Rental real estate is generally passive—you can only use its losses to offset other passive income. However, if you actively participated (e.g., approved tenants, made management decisions) and your MAGI was under $100,000, you could deduct up to $25,000 of rental losses against other income. This phased out between $100,000–$150,000 MAGI.
For married filing separately, the max deduction was $12,500, phased out between $50,000–$75,000.
Real Estate Professional Exception
If you spent 750+ hours and more than half your working time in real estate trades or businesses where you materially participated, your rental activities weren’t passive—allowing full loss deductions.
At-Risk Rules
Losses were limited to the amount you had “at risk”—the money you could actually lose. Qualified nonrecourse financing (like certain real estate loans) counted as at risk.
Vacation Home Rules
If you used your rental property personally for more than 14 days or 10% of rental days, you had to allocate expenses between personal and rental use.

Step-by-Step (High Level)
Part I – Rental Real Estate and Royalties
- List Each Property (columns A–C): Include the address, type of property, and your ownership share.
- Report Income (lines 3–4):
- Rentals → all rent received (cash or in-kind).
- Royalties → total royalties before deductions.
- Deduct Expenses (lines 5–19):
Include items like advertising, cleaning, insurance, repairs, mortgage interest, property taxes, depreciation, and utilities. - Depreciation (line 20):
- Residential buildings → 27.5 years
- Commercial → 39 years
Attach Form 4562 for property placed in service in 2010.
- Calculate Net Income/Loss (line 21–22):
Subtract expenses from income. Total in the “Totals” column.
Part II – Partnerships and S Corporations
- Use each Schedule K-1 you received.
- Report your share of income or loss (line 28).
- Distinguish passive vs. non-passive income.
- Apply limits using Form 6198 (at-risk) and Form 8582 (passive loss).
- Carry totals to Form 1040.
Common Mistakes and How to Avoid Them
1. Poor Recordkeeping
Failing to keep receipts or rental records can lead to disallowed deductions.
Fix: Keep receipts, invoices, lease agreements, and bank records for at least 3 years after filing.
2. Confusing Repairs vs. Improvements
- Repairs (fixing leaks, painting) → deductible now.
- Improvements (new roof, remodel) → depreciate over time.
Fix: Only deduct immediate repairs.
3. Wrong Form for Activity
If you provide substantial services (like daily cleaning or meals), report on Schedule C, not E.
Fix: Check IRS Pub. 527 for correct form usage.
4. Ignoring Passive Loss Limits
Rental losses can’t offset wages unless you meet the active participation or real estate professional tests.
Fix: Always file Form 8582 when rental losses exist.
5. Incorrect Personal-Use Allocation
Deducting 100% of expenses for a vacation home you also used personally is incorrect.
Fix: Allocate based on rental vs. personal days.
6. Missing Required Forms
Forgetting to attach Form 4562, 6198, or 8582 delays processing.
Fix: Review your forms checklist before filing.
7. Depreciating Land
Land is not depreciable.
Fix: Allocate cost between land and building using appraised or assessed values.
What Happens After You File
IRS Processing
E-filed returns process in about 3 weeks; paper returns take 6–8 weeks.
IRS Matching
The IRS matches your Schedule E with:
- 1099-MISC (royalties)
- Schedule K-1 (partnerships/S corps)
- Form 1098 (mortgage interest)
Discrepancies trigger notices or audits.
Passive Loss Carryforwards
Disallowed passive losses carry forward indefinitely until you have passive income or sell the property.
Audit Triggers
The IRS often reviews:
- Large deductions for repairs/improvements
- Unusually high travel or auto expenses
- Misclassified rental vs. business income
Penalties
Errors can result in 20% understatement penalties or more for negligence or fraud. Honest corrections through amended returns reduce penalties.
Future Impact
Depreciation methods chosen for 2010 continue in future years. Keep records for consistency.
FAQs
Q1: Do I have to report rental income if I rented for only a few weeks?
If you rented it fewer than 15 days, you don’t report the income or deduct rental expenses. Rent for 15+ days, and you must report all rental income.
Q2: Can I deduct rental losses against my salary?
Yes, if you actively participated and your MAGI is under $100,000. You can deduct up to $25,000 of losses. Above that, losses become passive and carry forward.
Q3: What’s the difference between a repair and an improvement?
Repairs maintain; improvements add value. Repairs are deductible now; improvements are capitalized and depreciated.
Q4: I received a Schedule K-1. Do I attach it to my return?
No. Keep it for your records—the IRS already has a copy. Use it to complete Part II of Schedule E.
Q5: I forgot to include rental income. What should I do?
File Form 1040-X with a corrected Schedule E. Attach documentation for expenses and pay any tax due with interest.
Q6: Can I deduct furniture and appliances for my rental?
Yes. For 2010, you could expense up to $500,000 under Section 179, or depreciate them over 5–7 years using Form 4562.
Q7: What happens to suspended passive losses?
They carry forward until you have passive income or sell the property in a taxable transaction, at which point they become fully deductible.
