The short answer: Form 1040EZ is a discontinued historical form, not a current alternative. The IRS retired it, along with Form 1040A, after the 2017 tax year. Current filers start with Form 1040.
The distinction matters because the wrong form, or outdated eligibility rules, can lead to unreported income or missed deductions and credits. This guide sets out a simple framework: identify the tax year first, then match the form to your circumstances. It is especially relevant for Australians with US income, US-source investments, or US filing obligations.
Key Takeaways
- Form 1040 is the main US federal individual return, with schedules added when needed.
- 1040EZ was discontinued for tax years after 2017; simple returns now use Form 1040.
- A shorter form is not better if it blocks income reporting or eligible credits.
- Taxpayers aged 65+ may use Form 1040-SR; nonresident aliens may need Form 1040-NR.
- Complex returns warrant current IRS instructions or a qualified tax professional.
IRS Form 1040 vs 1040EZ: Quick Comparison
| Feature | Form 1040 | Form 1040EZ |
|---|---|---|
| Availability | Current main individual return | Final year was 2017; historical only |
| Purpose | Reports income, adjustments, deductions, credits, tax, payments, refund or balance due | Simplified return for narrow filing situations |
| Eligibility | Depends on filing status, income, residency, dependents and other facts | Strict 2017 limits (below) |
| Deductions and credits | Accommodated through the form and schedules | No adjustments to income; only the earned income credit |
| Complexity | Can be short or involve many schedules | Always short, always restricted |
| Current path | Form 1040, 1040-SR or 1040-NR | None; there is no "upgrade" from 1040EZ |
The 2017 1040EZ instructions required taxable income below $100,000, single or joint status, no dependents, and filers under 65 and not blind. Those are historical rules for that year only.
What Are Forms 1040 and 1040EZ?
What Is Form 1040?
Form 1040 is the US Individual Income Tax Return. It calculates federal taxable income, tax, payments, and any refund or balance due.
The current return is modular. A two-page core form is supplemented by schedules only when relevant:
- Schedule 1: additional income and adjustments to income
- Schedule 2: additional taxes, such as self-employment tax
- Schedule 3: additional credits and payments
- Schedules A, B, C, D, E, F and SE: itemised deductions, interest and dividends, business income, capital gains, rentals, farm income, and self-employment tax
Two variants exist. Form 1040-SR is an optional version for taxpayers aged 65+, and it still allows itemising. Form 1040-NR is for certain nonresident aliens. Form 1040 does not apply to every person with a US tax obligation, so residency matters.
What Was Form 1040EZ?
It was the shortest, most restrictive return, built for uncomplicated income. Its 2017 version permitted wages, tips, taxable scholarships, unemployment compensation and taxable interest of no more than $1,500. It allowed no dependents and no adjustments to income, and its only credit was the earned income credit.
How Did the Filing Process Change?
For tax year 2018, the redesigned Form 1040 replaced the 1040, 1040A and 1040EZ. The IRS called it a "building block" approach: simple returns may need no extra schedules, while complicated ones add several.
So the correct form depends first on the tax year, then on your facts. A current filing, an older original return, an amended return, and a request for a historical copy each follow different paths. Amendments use Form 1040-X.
Form 1040 vs 1040EZ: What Is Better?
For current years there is no choice. The practical question is which current return and schedules apply.
Current-Year Returns
Start with Form 1040, then check whether you need:
- Form 1040-SR, if you are 65 or older and prefer it
- Form 1040-NR, if you are a nonresident alien with a filing obligation
- Extra schedules, based on income, deductions, credits and filing status
Residency drives the first split. Residents generally file 1040 or 1040-SR; nonresidents with filing obligations generally file 1040-NR.
Prior-Year Returns
Use the forms and instructions for that specific year. The IRS keeps a prior-year archive that pairs each year's form with its instructions. Don't substitute a current form without IRS or professional guidance.
Decision Checklist
Ask whether you have any of the following:
- W-2 wages or Form 1099 income
- Self-employment or gig income
- Dependents
- Itemised deductions
- Education or family credits
- Investments, rental income or foreign income
- Additional taxes
Each "yes" points toward added schedules. Choosing a simpler historical form to cut paperwork risks omitted income and missed benefits. Compare the full tax outcome, not page count.
Real-World Examples and Case Studies
A Simple Current-Year Return
Picture a taxpayer with only wage income who takes the standard deduction. They still file Form 1040. The return may need no schedules, so it stays short, but the form is the same one everyone uses.
For the 2026 tax year, the base standard deduction is $16,100 for single filers and $32,200 for married filing jointly, per Form 1040-ES.
A Historical 2017 Example
The 2017 Form 1040EZ included a worksheet for filers who could be claimed as someone else's dependent. That worksheet:
- Started with earned income plus $350
- Applied a minimum standard deduction of $1,050
- Capped the deduction at $6,350 (single) or $12,700 (married filing jointly)
That shows how narrow EZ was: dependents, age and income all affected eligibility. These figures apply to 2017 only.
When a Return Gets Complicated
Cross-border situations are where form choice gets tricky. Residency tests, treaty positions and nonresident rules can all change the answer.

Conclusion
Form 1040EZ is a former simplified return. Most people filing a current US federal individual return should evaluate Form 1040 and the schedules or alternative forms that match their circumstances.
The rule is practical: identify the tax year first, then review income, filing status, deductions, credits, residency and additional taxes. Where the return isn't straightforward, rely on current IRS instructions or qualified professional guidance.
Frequently Asked Questions
Should I use Form 1040 or 1040EZ?
Form 1040EZ is discontinued for current tax years. Current filers generally begin with Form 1040 or another applicable current return, while older returns require the form for that tax year.
Is the 1040EZ still a thing?
Not for current years. It may still appear in prior-year returns, historical records, or older amendments.
What is the point of a 1040 form?
It reports an individual's income and calculates federal tax, payments, and any refund or balance due. Schedules support more complex items.
What are the differences between the 1040 and 1040A tax forms?
Form 1040A was a simplified form for prior years. It barred itemised deductions and allowed fewer income types and credits. The current Form 1040 replaced both 1040A and 1040EZ.
What is a Form 1040A?
It was a former simplified return with fewer allowable income types, deductions and credits than the full Form 1040. It is not used for current tax years.
What is Form 1099-INT?
It reports taxable interest paid by financial institutions. Payers generally report amounts of $10 or more, but IRS Topic 403 says you must report interest even without the form. Reconcile it with your records.
