For readers in Australia, there is an extra wrinkle. A US citizen or resident alien living here may still owe a US return, and that filing is separate from your Australian one. This guide covers choosing the right version and tax year, getting the official form, completing it, and finding a return already on record.
Key Takeaways
- Download the correct year's Form 1040 and instructions from IRS.gov only.
- A Form 1040 is not a W-2, 1099, transcript or Australian tax return.
- If you already filed, don't file again; check IRS records, your software or your preparer.
- Confirm your US tax status before choosing Form 1040 or 1040-NR.
What Is Form 1040, and Do You Need It?
What Form 1040 does
Form 1040 is the US federal individual income tax return. You use it to report income, calculate tax, claim deductions and credits, and work out a refund or balance due. It pulls together figures from wage statements, investment records, business schedules and foreign-income forms.
Which version applies to you?
| Form | Purpose |
|---|---|
| 1040 | Standard individual return |
| 1040-SR | Optional version for taxpayers 65 or older; same schedules and instructions |
| 1040-NR | Nonresident alien return |
| 1040-X | Corrects a previously filed 1040, 1040-SR or 1040-NR, one form per year |
Living overseas does not by itself decide which return applies. Check your tax residency and filing status first.
A note for taxpayers in Australia
US citizens and resident aliens are taxed on worldwide income, so living in Australia doesn't end US filing duties. An Australian resident with only certain US-source income may need to look at Form 1040-NR instead.
The two filings are separate. The Australian Taxation Office (ATO) requires residents to declare foreign income in their Australian return, and filing in one country does not satisfy the other.
The calendars also differ: Australia's income year runs 1 July to 30 June, while the standard US year is 1 January to 31 December.
How to Get a Blank Form 1040
Find the form on the IRS website
Use only official IRS pages:
- Forms, instructions and publications: irs.gov/forms-instructions-and-publications
- Form 1040 page: irs.gov/forms-pubs/about-form-1040
- Current blank form (2025): irs.gov/pub/irs-pdf/f1040.pdf
- Matching instructions: irs.gov/instructions/i1040gi
- Prior-year archive: irs.gov/prior-year-forms-and-instructions
Match the form to the tax year
Select the year you are filing for, not the newest form by default. Line numbers, schedules, thresholds and instructions change. Check the year printed on both the form and the instructions before entering anything.
Choose how to access or generate it
- Download and print a blank PDF if you want to complete it by hand.
- Use tax software that generates the form automatically. This suits simple returns but may not support every foreign-income, foreign-asset, business or amended-return situation.
- Hire a professional to prepare the completed return. VJM Global, for example, prepares Form 1040 and 1040-NR returns, with pricing quoted by service scope.
Get a prior-year form when necessary
For a late return, an IRS notice or a review of an old filing, use the prior-year archive. The IRS provides these for past-due returns and says to file all returns due even if you can't pay in full. Don't use a current-year form for an earlier year unless the IRS tells you to.
Avoid unofficial forms and privacy risks
The IRS's March 2026 warnings cover fake refund and account-verification messages. Create IRS accounts directly through IRS.gov, and don't open unexpected links or attachments. Walk away from any site that asks for your Social Security number, bank details or payment before handing over a basic form.

How to Complete Form 1040: Step-by-Step
Gather your information first
Build a checklist:
- Identification, filing-status details and dependant information
- W-2s, 1099s, retirement statements and investment records
- Business records, deduction receipts and credit documentation
- Your prior-year return
Add foreign income statements, foreign tax records, currency-conversion support, foreign-account details, and travel or residency records. If you also earn salary, interest, capital gains or rent in India, keep those records too.
Complete personal information and filing status
Enter names, Social Security numbers or ITINs, addresses, spouse and dependant details exactly as official records show them. Anyone ineligible for an SSN must apply for an ITIN. The five filing statuses are Single, Married Filing Jointly, Married Filing Separately, Head of Household and Qualifying Surviving Spouse.
Common problems:
- Name mismatches with Social Security records
- Wrong taxpayer identification numbers
- Incomplete foreign addresses
- Choosing a filing status without checking eligibility
Report income from the right documents
Work from wages, interest, dividends, retirement income, self-employment, rental income and capital gains to the matching lines or schedules.
Report everything in US dollars. Use the exchange rate for the date income is received or an expense is paid. An annual average may apply when income arrives evenly through the year. The IRS has no official rate but accepts consistently used posted rates.
Apply adjustments, deductions and credits
Adjustments reduce adjusted gross income. You then take the standard or itemised deduction. Credits reduce tax directly.
Basic standard deductions for 2025 are US$15,750 (Single), US$31,500 (Married Filing Jointly) and US$23,625 (Head of Household). Nonresident aliens generally can't claim the standard deduction.
Always check current-year IRS rules rather than carrying forward old amounts. For 2025, the Child Tax Credit is up to US$2,200 per qualifying child under 17.
Australia-based filers should look at the Foreign Earned Income Exclusion (Form 2555, up to US$130,000 for 2025) and the Foreign Tax Credit (Form 1116). Taxes tied to excluded income can't also generate a credit.
Add schedules only when triggered
| Schedule | Use |
|---|---|
| 1 | Additional income and adjustments |
| 1-A | Qualified tips, overtime, vehicle-loan interest and senior deductions (new for 2025) |
| 2 | Additional taxes |
| 3 | Additional credits and payments |
| A | Itemised deductions |
| B | Interest and ordinary dividends |
| C | Sole-proprietor income or loss |
| D | Capital gains and losses |
| E | Rentals and royalties |
| SE | Self-employment tax |
Review, sign and submit
Reconcile totals between Form 1040 and each schedule. Confirm withholding and estimated payments, and check refund and bank details. Both spouses sign a joint return. Paper signatures must be handwritten. E-filed returns use PIN procedures, and Form 8879 authorises the practitioner method.
Australian filers should also check separate reporting thresholds:
- FBAR: foreign accounts exceeding US$10,000 in aggregate at any time
- Form 8938: for qualifying taxpayers abroad filing singly, assets over US$200,000 at year-end or US$300,000 at any time
How to Find a 1040 You Already Filed
Decide what record you need
- Return transcript: most original line items and schedules, excluding later changes
- Account transcript: basic return data, payments and later adjustments
- Record of account: the two combined
- Full copy: a photocopy of the filed return, which is not the same as a transcript
A transcript often suffices for mortgages, loans and tax preparation. Ask the requesting organisation whether it needs a full copy.
Check your IRS online account
Your IRS Online Account shows return information, transcripts, digital notices, balances by year and up to five years of payment history, after identity verification. Transcripts are free. Return transcripts cover the current and three prior years. Account transcripts are generally available online for the current and nine prior years.
Check your software or preparer
Sign in to the software account you used to e-file, or contact your preparer. Look for the e-file acceptance email, submission ID, signed Form 8879 and final PDF before requesting anything else.
Request an official copy
When a transcript won't do, file Form 4506. The fee is US$30 per return, copies are generally available for seven years from filing, and processing can take up to 75 days. Confirm the current form, fee and mailing address on IRS.gov before sending.
Already filed, or need older returns?
Don't file the same return twice because you can't find your copy. Confirm acceptance first. If you need changes, use an amended return.
Three periods get confused:
- Taxpayer record retention: generally 3 years, 6 years if unreported income exceeds 25% of gross income shown, and indefinitely if no return was filed
- Refund claims: generally the later of 3 years after filing or 2 years after payment
- Enforcement: IRS procedures use a six-year period for delinquent returns, which is not a refund window
How to Submit, Amend and Keep Your Return
E-file or paper
About 93.7% of individual returns were e-filed in fiscal year 2025. E-filing gives you an acceptance acknowledgement, and the IRS generally processes electronic Forms 1040 within 21 days. Mailed returns take six or more weeks for refunds.
If you mail from Australia, use these overseas addresses for Form 1040:
- No payment: Department of the Treasury, Internal Revenue Service, Austin, TX 73301-0215, USA
- With payment: Internal Revenue Service, P.O. Box 1303, Charlotte, NC 28201-1303, USA
Check the IRS address table first. These addresses do not apply to every related form.
If you have foreign income, foreign accounts or business activity, confirm your software or preparer supports every attachment.
Extensions and payments
An extension to file is not an extension to pay. For the 2025 return:
- Regular deadline: 15 April 2026
- Automatic abroad extension: 15 June 2026 for qualifying US citizens and resident aliens living abroad, but interest runs from 15 April
- Form 4868: generally to 15 October 2026, with no extra time to pay
Estimate and pay what you expect to owe. Failure to file costs generally 5% of unpaid tax per month (maximum 25%), and failure to pay generally 0.5% per month. Interest on underpayments is 7% annually from October to December 2026.
Correct errors and get help
Use Form 1040-X only after confirming the original return was processed. Amendments generally take 8 to 12 weeks, and sometimes up to 16 weeks.
If you have foreign income, prior-year gaps, business interests or complex US reporting, VJM Global's US tax compliance team, including CPAs and professionals trained in IRS rules, can help.
Keep these records in a secure file:
- Final return and schedules
- Source records
- Acceptance confirmation
- Payment evidence
- IRS correspondence
Frequently Asked Questions
How can I find my 1040?
A blank form comes from IRS.gov. A previously filed return comes from your IRS Online Account, your tax software or your preparer.
How can I check if I filed my taxes?
Look for the e-file acceptance notice, check your IRS account transcript, or confirm with your software provider or preparer.
What do I do if I already filed my taxes?
Don't submit a duplicate. Confirm processing status, and use Form 1040-X only if a genuine correction is needed.
How many years back can you file taxes?
The IRS says to file all returns due. Internal procedures generally look back six years, but refund claims follow separate limits of 3 years from filing or 2 years from payment.
How long does the IRS keep old tax returns?
Form 1040 copies are generally available for seven years from filing. Transcript availability is shorter, and your own retention duty is usually at least three years.
What is the Schedule 1 form?
Schedule 1 reports additional income and adjustments to income. You attach it to Form 1040 only if your circumstances require it.
