To report sublease income on your tax return, add up every dollar your subtenant paid you during the year, subtract the rent you paid your own landlord along with other allowable expenses, and report the net figure on Schedule E of your Form 1040. If you provided hotel-style services or ran the sublet through a short-term rental platform, the income belongs on Schedule C instead, and it will also be hit with self-employment tax. Either way, the IRS treats sublease rent as taxable rental income for the year you received it.
What Counts as Income
Your gross sublease income is everything the subtenant paid you for the right to occupy the space: monthly rent, late fees, and any non-refundable charges. Advance rent counts in the year the money reaches you, even if it covers a future period. Rent paid in December for January and February is December income.
Refundable security deposits are not income when you receive them. A deposit becomes income only in the year you decide to keep some or all of it because the subtenant broke the lease. Watch the label though. If a “security deposit” is really the last month’s rent under a different name, it’s advance rent and taxable right away.
The 14-Day Exception
If the property is your residence and you sublease it for fewer than 15 days during the year, you report none of the income and deduct none of the expenses. The dollar amount doesn’t matter. Someone who rents out a spare room for two weeks at $500 a night keeps the $7,000 tax-free under this rule.
The property has to qualify as your residence, which means you personally used it more than the greater of 14 days or 10 percent of the days it was rented at a fair price.
Expenses You Can Subtract
You pay tax on net profit, not gross rent. For most sublessors, the largest single deduction is the rent paid to your own landlord under the master lease. Other ordinary and necessary expenses include utilities you cover for the subtenant, minor repairs, cleaning between tenants, renter’s insurance covering the rental activity, and advertising to find a subtenant.
Proportional Allocation for Partial Sublets
If you sublease only part of your home, or sublease for only part of the year, shared expenses have to be split. Use two fractions. The space fraction is the subleased area divided by total living area: 200 square feet in a 1,000-square-foot apartment is 20 percent. The time fraction is fair rental days divided by days in the year: 120 rental days is roughly 33 percent. Multiply them, and apply the result to shared costs like the master lease payment and utilities. In this example, you could deduct about 6.6 percent of those shared annual costs.
Expenses tied only to the rental space, like repainting the subtenant’s room, are fully deductible without any allocation. Keep receipts and the square footage measurements; the burden of justifying your method falls on you.
Schedule E or Schedule C
The form depends on what you’re actually running. This isn’t cosmetic; the wrong choice changes what you owe.
Schedule E (Form 1040) is the right form for a standard sublease where you provide the space and the subtenant handles their own daily life. Long-term residential sublets almost always land here.
Schedule C applies when you provide substantial services primarily for the subtenant’s convenience. The IRS points to regular cleaning, changing linens, and maid service as examples. If your sublease looks more like a hotel stay than a landlord-tenant relationship, use Schedule C. Short-term rentals through platforms like Airbnb often qualify because hosts typically furnish the space, stock toiletries, set up Wi-Fi, coordinate check-in, and clean between guests. There’s no bright-line rule; the determination turns on the overall character of what you provide.
Why the Choice Matters
Schedule C net income above $400 for the year is subject to self-employment tax at 15.3 percent (12.4 percent Social Security, 2.9 percent Medicare). For 2026, the Social Security portion applies to the first $184,500 of combined wages and self-employment earnings; the Medicare portion has no cap.
A sublessor who nets $10,000 on Schedule E pays only income tax on that profit. The same $10,000 on Schedule C also draws roughly $1,530 in self-employment tax. Half the self-employment tax is deductible as an adjustment to income, which softens the hit but doesn’t erase it.
How the Numbers Flow onto Schedule E
For a passive sublease past the 14-day threshold, the entries on Schedule E, Part I are:
- Line 2, rental days: the number of fair rental days and personal use days. The IRS uses these to check your expense allocation.
- Line 3, rents received: total gross sublease income before any expenses.
- Line 14, repairs: the proportional cost of repairs attributable to the rental use.
- Line 17, utilities: the proportional share of utility costs tied to the sublease.
- Line 19, other expenses: the rent you pay your primary landlord goes here. Add a short description like “master lease rent” next to the amount.
Schedule E subtracts total expenses from gross rents and produces your net rental income or loss. The result flows to Schedule 1 and then onto Form 1040 with the rest of your taxable income.
When Expenses Exceed Income
If your deductions come out higher than your rent, you have a rental loss. Rental activities are generally passive, so losses only offset other passive income. One exception rescues most individual sublessors: if you actively participate, you can deduct up to $25,000 of rental losses against non-passive income each year.
Active participation means making meaningful management decisions: approving the subtenant, setting rent, authorizing repairs. Most hands-on sublessors clear that bar. You also need at least a 10 percent interest in the activity.
The $25,000 allowance phases out as modified adjusted gross income rises above $100,000, dropping 50 cents for every dollar over, and disappearing at $150,000. If you’re married filing separately and lived with your spouse at any point during the year, the allowance is zero.
Losses you can’t use now carry forward to future years, or you can deduct them in full when you dispose of the entire activity. Report the limitation on Form 8582 and attach it to your return.
If You Got a 1099-K
Platforms like Airbnb, VRBO, and payment apps like Venmo may send you a Form 1099-K reporting the gross payments they processed. For 2026, a 1099-K is required when payments exceed $20,000 and you have more than 200 transactions during the year.
The form doesn’t change what’s taxable. All sublease income has to be reported whether or not a 1099-K arrives. When one does arrive, the gross number usually won’t match your taxable income because it doesn’t subtract your expenses or separate out non-taxable amounts that ran through the same account.
A common problem: platforms sometimes mix personal reimbursements (a roommate paying you back for groceries) into the same payment stream as rent. If your 1099-K includes those, reconcile the amounts so you only report actual sublease income. Marking personal payments as non-business inside the app helps at tax time.
Quarterly Estimated Tax
Sublease rent arrives with no withholding. If you expect to owe $1,000 or more in total tax after withholding and credits, the IRS expects quarterly estimated payments, typically due April 15, June 15, September 15, and January 15 of the following year. You avoid the underpayment penalty by paying at least 90 percent of the current year’s tax through withholding and estimated payments, or 100 percent of the prior year’s.
State and Local Occupancy Taxes
Federal income tax isn’t the whole picture. Many cities and counties charge occupancy or transient lodging taxes on short-term rentals, generally stays under 30 days. Combined rates range from zero to over 20 percent depending on the jurisdiction. Some platforms collect and remit these on your behalf, but platform collection doesn’t always cover every local layer. Check with your local tax authority. Occupancy taxes you pay are generally deductible on your federal return.
Records to Keep
The burden of proof for every deduction sits with you. Keep the sublease agreement, bank statements showing rent in and rent out, receipts for each deductible expense, and a log of fair rental days and personal use days. If you allocate proportionally, document the square footage and your calculation.
Failing to report sublease income, or underreporting it, can trigger a 20 percent accuracy-related penalty on the underpaid tax plus interest. The risk climbs when a platform already reported your gross receipts on a 1099-K, because the IRS matching system will flag the gap automatically.
