If you owe the IRS more than you can comfortably pay, your financial information can be one of the most significant elements in debt resolution. IRS forms 433-A and 433-F are designed to give the IRS an idea of your income, assets, liabilities, and needed living costs for the assessment of your ability to pay.

The initial error is to round the expenses on these forms. In fact, the current Form 433-A (OIC) actually asks taxpayers to round applicable amounts to the nearest dollar. The greater issue is making an unsound estimate of costs, whether it be under- or over-estimating, without adhering to the guidelines provided in the form.

You can better prepare and defend a financial statement if you know the difference.

If your monthly budget is a well-thought-out savings plan, and you have calculated the average monthly expense to be $1,247.63. If the form requires a number to be rounded to the nearest dollar, then enter $1,248.

That’s not like you’re looking at your finances and saying, “Let’s put in $1,200 because it’s simple.

The IRS currently uses Form 433-A (OIC), which requires the average monthly expenses and rounding to the nearest dollar. It also identifies the difference between expenses that would be subject to the allowable standard and expenses that would be subject to actual expenses.

Thus, the actual rule is:

Round when instructed to round, but don’t approximate an accurate calculation with a guess.

The purpose of the 433-A and the 433-F is to allow the IRS to determine whether you have money available to meet an outstanding tax liability.

For instance, Form 433-F gathers data on monthly essential expenditures, such as food, travel, housing, medical expenses, kid care, taxes, student loans, and some other payments.

The amount of income reported and allowable expenses can impact the amount of money that you have available each month for the IRS to consider.

Try an example that is simplified:

• Monthly household income: $7,000
• Actual allowable expenses: $5,800
• Remaining amount: $1,200

If it is reported as a casual expense, though, of $5,300, the remaining amount seems to be $1,700.

In isolation, that $500 may not seem like a tremendous amount, but over time it could make a significant difference in what financial picture the IRS sees.

Do not take for granted that all financial statements are prepared exactly in the same way.

Collection Information Statement 433-A is for Wage Earners and Self-Employed Individuals. There’s also a special 433-A (OIC) version of the current 2026 version for Offer in Compromise applications.

Form 433-F is a Collection Information Statement to get current financial details concerning an individual’s capacity to meet a current tax debt.

Caution needs to be taken with financial reporting for both types, but directions and intent may vary. Please use the current worksheet and the associated instructions for every assignment and not an old one or an example on the internet.

Another big problem is that people are not separating their real expenses from their IRS allowable expenses.

Taxpayers’ ability to pay delinquent taxes is determined through the use of the IRS Collection Financial Standards. The standards apply to items including food, clothing, healthcare, housing, utilities, and transportation.

The IRS applies a fixed amount, or standard allowance, to certain costs instead of the actual dollar amount that the person reports paying.

This includes, for instance, food, housekeeping materials, clothing, personal care, and other costs. Household size, location, and circumstances may affect the type of housing and transport available.

Just because you can enter a specific amount in each category, it doesn’t necessarily mean you’re better off doing so in order to improve your finances.

Some costs are variable, depending on the amount you pay.

The current Form 433-A (OIC) guides how taxpayers should report their actual expenses, unless in certain circumstances. Specifically defines food, clothes, and other expenditures and some out-of-pocket health care costs as categories where the standard can be used even if the actual expenditure is less than the standard.

Form 433-F also requests actual monthly expenses and gives directions on how to convert expenses that are not paid monthly into monthly expenses.

Payments on a bill made quarterly, for instance, are to be divided into three monthly payments on Form 433-F. There are different conversion methods for weekly and biweekly expenses.

This is sounder than just estimating what your monthly expense is “probably”.

Collect multiple months’ worth of financial statements prior to completing your form.

Useful documents might be:

• Bank statements
• Credit-card statements
• Utility bills
• Rent/Mortgage Statements
• Insurance bills
• Medical receipts
• Child-care invoices
• Vehicle expenses
• Loan statements
• Tax payment records
• Other recurring bills

The IRS might ask for proof of income and expenses, such as pay statements, bank and investment statements, loan statements, and recurring bills.

After you have taken the records, work out the underlying expense first. Afterwards, use the rounding instruction in the form.

Being understated can make expenses look lower than they actually are.

If your typical vehicle operating costs are:

1. Fuel: $230
2. Insurance: $145
3. Maintenance: $85
4. The monthly average for the registration and other fees: $40
5. The base rate that you already pay is $500 per month.

The catch to this is that entering $450 for the sake of convenience is not a good representation of the cost.

This is the same for housing, utilities, medical expenses, child care, and any category that it fits into.

There is a two-way street to accuracy.

Some taxpayers may find themselves tempted to spend more so that they appear to be paying less. This can also be a challenge if the IRS requests documentation to support the claim.

An expense should be:

• Genuine
• Properly categorized
• In line with your financial records
• Permitted under the IRS rules that apply.
• Supported if information is needed

The objective isn’t to make your expenses as high as possible. It’s intended to share an honest financial portrait.

Changes to the IRS’ Collection Financial Standards were effective beginning June 29, 2026. These standards may be subject to change, and the IRS points out that taxpayers should use the most current figures and not a table from an old printout.

The standards include:

• Food, Clothing and Other Items

The food, housekeeping supplies, apparel and services, personal care products and services, and miscellaneous expenses are included in the national standards.

• Health Care

The IRS prescribes national standards for some out-of-pocket medical care costs. These include medical services, prescription drugs, and medical supplies. This standard is in addition to the cost of health insurance.

• Housing and Utilities

There are differences in housing quality across locations and household types. These may cover rent or mortgage-related expenses, utilities, insurance, maintenance, and some communications costs.

• Transportation

Transportation standards include ownership and operating costs. Operating expenses can involve fuel, insurance, maintenance, repairs, registration, licenses, parking, and tolls.

It is frequently more significant to grasp these categories rather than to fret over whether an amount is $00 or $01.

Don’t simply alter the number to fit the standard.

If actual expenses exceed applicable standards, the IRS says they must be documented and substantiated. In certain cases, the IRS will take into account expenses in excess of the standards if the facts show that the standards are not satisfactory for basic living costs.

It is particularly important to have documentation if your situation is atypical.

For instance, other expenses may be incurred due to situations including:

1. The medical treatment necessary to achieve significant results.
2. Special transportation requirements
3. Certain family circumstances
4. Cost of earning income – the expenses required to generate income.
5. Other scenarios which require conventional allowances to be insufficient to meet the requirements.

Treatment will depend on the facts and the IRS rules.

1. Apply Old IRS Standards

Collection standards change. According to the IRS, the new 2026 standards are effective June 29, 2026.

2. Estimating rather than calculating

Avoid estimating when a record is available to determine an average of your bank account.

3. Tackling all expenses the same way

Some categories have standards and others have special rules or actual expenses.

4. Double-Counting Expenses

Care should be taken not to double-count the same costs.

5. Inadequate record-keeping or bookkeeping.

Self-employed taxpayers need to distinguish business expenses from household expenses properly. For instance, on Form 433-F, the self-employment income is reported after the ordinary and necessary business expenses.

6. Ignoring Irregular Expenses

Monthly costs may have to be calculated instead of being discounted by the year, quarter, week, or biweekly.

7. Not keeping documentation

The IRS may request documentation of your expenses.

Use this checklist:

• Get the latest IRS form.
• Review the existing Collection Financial Standards.
• Collect up-to-date financial statements and bills.
• Make careful calculations of the average monthly expense.
• Follow the form’s instructions to convert non-monthly bills.
• Distinguish the actual cost from the standard allowances.
• Round answers as directed.
• Double-check your work!
• Ensure that income and expenditure are balanced.
• Make copies of the completed form and supporting documents.
• Have an explanation for some odd expenses.

When you have a tax liability, you can be tempted to make the documentation easy and easy. Forms 433-A and 433-F are not casual budgeting worksheets, but financial statements.

The information will be used by the IRS in considering collection options, and the IRS may seek documentation as needed. Financial information may also be needed for financial hardship and collection alternatives like Currently Not Collectible status, the IRS also adds.

A minor rounding error that conforms to the form of the directions is normally not an issue. If there are unexplained estimates, figures that fluctuate from one year to the next, or supporting expenses that are not justified, this can cause significant issues.

The big words on the headline deserve a big qualification: “Don’t round your expenses” is not to be taken literally in the sense that the IRS does not round its expenses. The current Form 433-A (OIC), for instance, clearly instructs you to round to the nearest whole dollar applicable amounts.

It’s important to avoid arbitrary rounding, unsupported estimates, or inflating or deflating expenses to make your finances look different.

1. Why shouldn’t I round expenses arbitrarily on IRS Forms 433-A or 433-F?

You should report expenses accurately and round numbers according to the instructions in the form you are filling out. If you do not follow the rounding instructions, the IRS may think a person cannot afford to pay taxes.

2. Can I use IRS standard expenses instead of my actual expenses?

In some expense categories, the taxpayer is instructed or allowed, at the IRS’s discretion, to use a particular Collection Financial Standard. In the other categories, expenses should be estimated as of their actual amount. Always follow the instructions for the forms and categories.

3. What documents should I keep for expenses reported on Form 433-A or 433-F?

It is essential to save all the documents that back up the information provided in the forms, including bills, bank receipts, loan statements, paychecks, insurance claims, and any other documents that can represent the income or expenses of the taxpayer. The IRS may request to review the documents to verify reported information.
