What Are IRS Allowable Expenses? National and Local Standards

IRS allowable expenses are the monthly living costs the IRS lets you keep for yourself before deciding how much you can pay toward back taxes. The agency publishes Collection Financial Standards that cap what counts as reasonable spending on food, clothing, personal care, out-of-pocket health care, housing, and transportation, and then treats whatever income remains after those allowances as available to pay down your balance.¹ These rules are separate from the “ordinary and necessary” test that governs business deductions on a tax return; they only come into play once you owe money you cannot fully pay.

When the Standards Actually Apply

If you are current on your returns and your balance is paid, none of this matters. The Collection Financial Standards come out when you are asking the IRS for something: an installment agreement you cannot fully cover within the standard timeframe, an Offer in Compromise, or Currently Not Collectible status on your account.

Straightforward installment agreements often skip financial analysis entirely. When analysis is required, the IRS compares your income and assets against your allowable expenses to calculate disposable income, and that number drives the monthly payment or lump-sum offer the agency will accept.¹

One rule reshapes the whole calculation. Under the six-year rule, if you can pay your entire liability including penalties and interest within six years, the IRS generally allows your actual living expenses even when they exceed the published standards, and may also allow other payments such as minimum student loan or credit card obligations.¹ If you cannot pay within six years, the standards apply strictly.

National Standards for Food, Clothing, and Personal Items

The IRS sets flat monthly allowances for five categories of personal spending: food (groceries and dining out), housekeeping supplies, clothing and footwear, personal care products and services, and a miscellaneous category.² These amounts are the same everywhere in the country.

The standards published in April 2025 remain in effect through June 2026 because of delayed data from the Bureau of Labor Statistics and Census Bureau. The current monthly totals are:²

One person: $839
Two persons: $1,481
Three persons: $1,753
Four persons: $2,129

You get the full national standard amount for your household size without submitting receipts, even if you actually spend less. It is one of the few areas where the IRS does not demand proof of every dollar.¹ Claiming more than the standard is possible, but you have to document that the higher spending is necessary for basic living expenses.³

Out-of-Pocket Health Care

Health care has its own national standard, separate from food and clothing. The IRS recognizes that older taxpayers face higher medical costs, so the allowance is age-tiered:

Under 65: $84 per person per month
65 and older: $149 per person per month

These figures cover co-pays, prescription medications, dental work, vision care, and other medical costs not paid by insurance. Each household member gets the full amount without substantiation. If your actual costs run higher, common when someone in the household manages a chronic condition, you can claim more, but the expenses must be medically necessary and documented. Elective procedures such as cosmetic surgery do not qualify.⁴

Local Standards for Housing and Transportation

Housing and transportation costs swing too widely by region for a single national number, so the IRS publishes caps by county and household size using Census Bureau and Bureau of Labor Statistics data.³

The housing standard covers rent or mortgage payments, property taxes, homeowner’s or renter’s insurance, homeowner association dues, and utilities including electricity, gas, water, trash, and phone service. Unlike the national standards, the local standard is a ceiling, not a guaranteed amount. You receive the lesser of your actual documented costs or the published limit. If your county’s cap for a family of three is $2,672 and you pay $2,400, the IRS allows $2,400. If you pay $3,100, you are capped at $2,672 unless you can justify a deviation.

Transportation splits into two pieces. The ownership allowance covers a vehicle loan or lease payment. The operating allowance covers maintenance, repairs, insurance, fuel, registration, parking, and tolls, but not personal property taxes on the vehicle.⁵ If you have no car payment, you still receive the operating allowance for what it takes to keep your vehicle running. If you rely on public transit instead of owning a car, you receive an allowance for those costs.

Other Necessary and Conditional Expenses

Beyond the standard categories, the IRS treats certain other costs as allowable when they are required for health, welfare, or income production.³ Health insurance premiums are typically the largest item. Court-ordered child support and alimony come off your income before the affordability calculation, because you face legal consequences for skipping them. Involuntary payroll deductions like union dues and mandatory retirement contributions count for the same reason: you cannot opt out. Current-year federal, state, and local taxes are treated as necessary so you do not fall behind on new obligations while paying off old ones.

A separate category of conditional expenses may be allowed depending on your situation. Charitable contributions can qualify when tithing or donating is a condition of employment; the IRS uses the example of a minister whose contract requires tithing. Education expenses are conditional when they are required for a physically or mentally challenged child with no adequate public option, or when a professional needs continuing education to maintain a license, such as an attorney’s bar requirements or a teacher’s certification credits.³ Term life insurance premiums are sometimes allowed; investment-heavy whole life policies generally are not.

The six-year rule shapes conditional expenses too. If you can fully pay your liability within six years including accruals, conditional expenses are more likely to go through. If you cannot, the IRS may give you up to one year to reduce or eliminate certain conditional costs before recalculating what you can afford.³

Going Above the Standard Amounts

The published caps are not absolute. The IRS can approve higher amounts when the standard is genuinely inadequate, but every deviation has to be verified, reasonable, and documented.

Situations that commonly justify higher spending include:

A prescribed medical diet, such as gluten-free or diabetic-specific foods, supporting food expenses above the national standard.⁶
A physical disability requiring accessible housing, or a household with more members than the standard tables accommodate.⁶
No cheaper housing alternative — if the IRS determines you could not rent comparable housing for less than your current mortgage payment, the full mortgage may be allowed even above the local standard.⁶
Long commutes for work, when documented by mileage, supporting operating costs above the transportation standard.⁶
Reasonable costs associated with relocating to more affordable housing, allowed on a temporary basis.

The operative word in every deviation request is substantiate. The IRS will not take your word for it. Bring medical documentation, employment records showing commute distance, comparable rental listings, whatever proves the higher cost is real and unavoidable.

The Form and the Paper Trail

The primary document in a collection case is Form 433-A, the Collection Information Statement, which lays out your income, assets, and monthly expenses in detail.⁷ After reviewing the form, the IRS may request supporting documents including bank statements, pay stubs, loan agreements, insurance policies, and utility bills.

If you are self-employed, Form 433-A asks you to calculate average monthly business income and expenses using a prior period of three, six, nine, or twelve months.⁷ The IRS picks whichever period best reflects typical earnings, so seasonal businesses often need a full year of records to show the real picture.

Organize by category. One folder for housing costs, another for medical expenses, another for court-ordered payments. The taxpayers who run into trouble are almost never the ones with unusual expenses. They are the ones who cannot prove the ordinary ones.
