Carrying charges are the recurring costs you pay to hold an asset over time, and the tax code splits them into two buckets: charges you can deduct in the year you pay them, and charges you must add to the asset’s cost basis. Which bucket applies depends on what the asset is, whether it produces income, and in some cases a yearly election you make on your return. Property taxes, interest on acquisition debt, insurance premiums, storage fees, and regulatory compliance costs are the usual examples, and they accumulate whether or not the asset produces any revenue.
Getting the classification right matters because every carrying dollar reduces your real return. A parcel that appreciates $20,000 over five years but costs $25,000 to hold is a net loss regardless of the sale price.
Real Estate Holding Costs
Undeveloped or non-income-producing real estate generates the most visible carrying charges. You pay property taxes each year based on assessed value, with effective rates ranging from under half a percent to more than two percent of market value depending on jurisdiction. On top of that, you pay mortgage interest on any acquisition financing and premiums for liability insurance. None of these costs stop while the property sits empty.
Treatment differs sharply from actively managed rental property. Operating expenses on a rental are straightforward deductions against rental income. On land or property producing no income, you face a choice each year: deduct the carrying charges against your other income, or capitalize them into the property’s cost basis. That choice is governed by Section 266.
The Section 266 Election
Section 266 lets you elect to capitalize carrying charges that would otherwise be deductible, adding them to the property’s basis instead of claiming a current-year deduction.1eCFR. 26 CFR 1.266-1 – Taxes and Carrying Charges Chargeable to Capital Account and Treated as Capital Items For unimproved and unproductive real property, eligible charges include annual property taxes, mortgage interest, and other carrying charges. The election has to be made each year for this type of property; it does not automatically carry forward.
Why give up a current deduction? Usually because it isn’t worth much right now. If you’re in a low-income year or already showing a loss, the deduction saves little in tax. Capitalizing the charges builds up your basis, which reduces the taxable gain when you eventually sell. If you expect to be in a higher bracket at sale or the property is appreciating quickly, the deferred benefit through a smaller capital gain can outweigh the immediate write-off.
How to Make the Election
You elect by attaching a statement to your original tax return for the year, filed by the due date including extensions. The statement identifies the property, describes each charge being capitalized, and lists the dollar amounts. You then do not claim those charges as deductions on the same return. There is no special IRS form; the statement plus consistent treatment on the return is the election.1eCFR. 26 CFR 1.266-1 – Taxes and Carrying Charges Chargeable to Capital Account and Treated as Capital Items
The election works differently depending on the type of property. For unimproved and unproductive real property, you decide year by year. For property under development or construction, the election locks in until the project is completed. For personal property, it applies until the property is installed or first put to use, whichever is later. You cannot switch midway through a construction project and start deducting charges you previously elected to capitalize.
Investment Carrying Charges
Financial assets carry their own holding costs, and the tax treatment varies by category.
Margin Interest
Margin interest paid to a broker for borrowed funds used to buy securities qualifies as investment interest expense under Section 163(d). It is deductible, but only up to your net investment income for the year, which generally means interest, ordinary dividends, and certain other investment income minus investment expenses.2Office of the Law Revision Counsel. 26 U.S. Code 163 – Interest
You calculate the deduction on IRS Form 4952. Any excess over net investment income carries forward and is treated as investment interest paid in the following year, with no expiration on the carryforward.3Internal Revenue Service. About Form 4952, Investment Interest Expense Deduction
Advisory and Custodial Fees
Fees charged by brokerages, trust companies, or investment advisors to manage and safeguard your assets are carrying charges, but they produce no current tax benefit for most individual investors. These fees were formerly miscellaneous itemized deductions subject to a 2% floor. The Tax Cuts and Jobs Act suspended that deduction starting in 2018, and the One Big Beautiful Bill Act of 2025 made the elimination permanent.
Brokerage Commissions
Commissions paid to buy or sell securities are not recurring carrying charges. A purchase commission is added to the security’s cost basis, and a selling commission reduces the amount realized on sale.4Internal Revenue Service. Topic No. 703, Basis of Assets
Physical Commodities
Investors holding physical gold, silver, or other commodities face tangible costs paper investments avoid. Storage at a secure depository typically runs 0.30% to 0.50% of the metal’s market value per year, and insurance may be bundled in or charged separately. These are ordinary carrying costs on an asset that produces no income, so every dollar in vault fees is a dollar the commodity’s price must appreciate before you break even.
Inventory Carrying Charges and UNICAP
Businesses that hold physical goods face warehousing rent, utilities for climate control, insurance against fire, theft, and damage, plus interest on any inventory financing. Whether you can deduct these costs currently or must fold them into inventory value depends on your size.
Under the Uniform Capitalization rules in Section 263A, businesses that produce property or acquire goods for resale must capitalize both direct costs and a share of indirect costs, including taxes, into the cost of their inventory.5Office of the Law Revision Counsel. 26 U.S. Code 263A – Capitalization and Inclusion in Inventory Costs of Certain Expenses The tax benefit is deferred until the inventory sells and is recovered through cost of goods sold. UNICAP is a timing rule, not a disallowance rule.6Internal Revenue Service. Section 263A Costs for Self-Constructed Assets
Small Business Exemption
The Tax Cuts and Jobs Act created an exemption for small business taxpayers, defined as businesses other than tax shelters whose average annual gross receipts for the three prior tax years do not exceed a threshold indexed for inflation. For taxable years beginning in 2025, that threshold is $31 million.7Internal Revenue Service. Rev. Proc. 2024-40 Businesses below the line can deduct inventory-related carrying charges in the year incurred rather than capitalizing them. The figure adjusts upward each year.
Construction Period Interest
When you are building or producing real property, the rules stop being elective. Under Section 263A(f), interest incurred during the production period must be capitalized when the property has a long useful life, when the estimated production period exceeds two years, or when the production period exceeds one year and the project costs more than $1 million.5Office of the Law Revision Counsel. 26 U.S. Code 263A – Capitalization and Inclusion in Inventory Costs of Certain Expenses
The production period starts with the first physical activity on the project, such as clearing land, demolition, or breaking ground on infrastructure. From that point until completion, interest on debt allocable to the project gets folded into the property’s basis rather than deducted currently. The small business gross-receipts exemption also applies here.
What Capitalization Means at Sale
Every capitalized carrying charge increases your cost basis. When you sell, your taxable gain equals the sale price minus that basis, so a higher basis means a smaller gain and less tax. The capitalize-or-deduct decision is fundamentally a timing question about when the tax benefit lands.
You report the sale of a capital asset on Form 8949, listing the proceeds, your adjusted basis including any capitalized carrying charges, and the resulting gain or loss. Totals flow to Schedule D of Form 1040, where the tax on capital gains is calculated.8Internal Revenue Service. About Form 8949, Sales and Other Dispositions of Capital Assets
Records matter. If the IRS questions your basis, you need documentation showing each charge, the year it was incurred, and the election statement you filed for that year. Without that paper trail, you risk losing the basis adjustment and paying tax on a larger gain than you actually realized.
Fixing a Prior Misclassification
If you have been deducting carrying charges that should have been capitalized, or capitalizing charges that qualified for an immediate deduction, correcting the error generally requires Form 3115, Application for Change in Accounting Method.9Internal Revenue Service. About Form 3115, Application for Change in Accounting Method This is not an amended-return situation. A change in classification of carrying charges is treated as a change in accounting method, which means following the IRS’s formal procedures and calculating a Section 481(a) adjustment for the cumulative difference. Professional help on this filing is worth the cost; errors in the adjustment can invite additional scrutiny.
