IRS Form 1040 vs 1040-NR for Bangladeshi Founders: Which Return Do You File?

IRS Form 1040 vs 1040-NR for Bangladeshi Founders comes down to one question: does the IRS treat you as a US resident or as a nonresident alien? Form 1040 is the standard individual income tax return for US citizens and resident aliens, who are taxed on their worldwide income. Form 1040-NR is the return for nonresident aliens, who are taxed only on income from US sources or income connected to a US business. A Bangladeshi founder who lives in Bangladesh and owns a US LLC is almost always a nonresident alien, so Form 1040 is the wrong form, and Form 1040-NR applies only when the owner has US-connected income. Many foreign-owned LLCs also have a separate annual filing, Form 5472 with a pro forma Form 1120, which has nothing to do with either personal return. This guide explains the difference, who files what, the deadlines, the penalties, and how Finset Formation can support you.

What is IRS Form 1040?

Form 1040 of the Internal Revenue Service (IRS) is an individual income tax form in the USA. It is used by US citizens, those who have green cards, and other individuals whom the IRS considers resident aliens to report their income on an annual basis. The most significant aspect of Form 1040 is that it reports worldwide income, meaning that income received from any part of the world is reported regardless of its place of origin.

When filling out Form 1040, a taxpayer has the right to use the standard deduction, select a filing status, and file together with a spouse. Furthermore, the IRS prepares instructions for Form 1040 and schedules covering business income, investments, and credits.

For Bangladeshi founders, it is essential to understand that Form 1040 is a form used by individuals who are considered US tax residents. Owning a US LLC does not make one a US tax resident and therefore does not imply filing Form 1040.

What Is IRS Form 1040-NR?

The IRS Form 1040-NR is used by nonresident aliens to file their US income taxes. This form covers the income that is subject to taxation under the nonresident rules, which include income sourced within the US and the income that is effectively connected with a US trade or business.

There are numerous practical differences between Form 1040 and Form 1040-NR. First, a nonresident alien cannot use the standard deduction, cannot file the joint return along with his/her spouse, and reports only the income taxable in the US. The US government issued specific instructions and schedules related to the form, which include schedules for income that is not effectively connected with a US business.

A nonresident alien has to file the Form 1040-NR in some cases, but may choose to do so in other cases, for example, to claim a refund of tax or treaty benefit. Whether filing the form is mandatory for you does not depend on whether you have a US business.

Form 1040 vs 1040-NR: Key Differences

The two forms look similar at first glance, but they apply to different taxpayers and cover different income.

Feature	Form 1040	Form 1040-NR
Taxpayer Type	US citizens and resident aliens	Nonresident aliens
Income reported	Worldwide income	US-source income and income connected with a US business
Standard deduction	Generally applicable	Usually not applicable
Joint tax return with spouse	Possible	Not possible
Common Bangladeshi entrepreneur	Unlikely to apply	Applicable only if you have income connected with the US
Taxpayer ID required	SSN or ITIN	SSN or ITIN

The most common mistake is assuming that every foreign founder with a US LLC files one of these forms every year. In practice, many Bangladeshi founders file neither personal return, because their income is earned abroad and falls outside the US tax net.

Are Founders from Bangladesh Resident or Nonresident Aliens?

An individual not being a US citizen would be considered a resident alien or nonresident alien by IRS according to some criteria. There are two main criteria for the IRS to classify a person as a resident alien or nonresident alien. These criteria are:

1. The green card test. An individual has the status of a lawful permanent resident of the US during the year.
2. The substantial presence test. An individual is physically present in the United States for at least 31 days during the year and over 183 weighted days within a period of three years. The weight is counted as all days of presence in the current year, one third of the days of presence in the previous year, and one sixth of the days of presence in the year prior to the previous one.

An entrepreneur of Bangladesh nationality who resides in Bangladesh, lacks a green card, and does not make frequent trips to the US is a non-resident alien. If you live for an extended period of time in the US, such as with a long visa or multiple extended visits, be careful with counting your days, since substantial presence test will affect your status. There are special exemptions and treaty provisions, so consult a US tax expert if you travel frequently.

Does a Bangladeshi LLC Owner Need to File Form 1040-NR?

Not necessarily. A single-member LLC owned by a nonresident alien is generally disregarded as a separate entity for US income taxation purposes, so the IRS ignores the LLC and looks behind it. Whether or not the owner has to file something depends on the source of income.

It would generally not be necessary to file Form 1040-NR if:

• Your services are performed abroad, such as being a freelancer operating from Dhaka to serve foreign clients, since the income is likely to be considered foreign source
• Your LLC does not conduct any business in the US and has no US source income that is not subject to tax
• There is no business operation conducted by your LLC during the year

It would generally be required to file Form 1040-NR if:

• Your LLC operates a US trade or business and earns effectively connected income
• Your LLC has US source income that has not been entirely subjected to withholding
• You would like to get a tax refund or take a treaty based position
• Your LLC has earned US rental income from its properties

Since this depends largely on the particular circumstances, for example whether your activities are conducted abroad, where the inventory is located, and who your clientele are, this is something that you should ask a tax professional about.

Effectively Connected Income vs FDAP Income

Income received by non-residents is broadly classified into two categories by the IRS, and each category is taxed differently. The knowledge of the category to which your income belongs will help you determine what form to file.

Category	What It Means	How It Is Taxed
Effectively Connected Income (ECI)	Income from a US trade or business	Graduated tax rates, reported on Form 1040-NR
FDAP income	Fixed, determinable, annual, or periodical US-source income such as certain dividends, interest, and royalties	A flat 30% rate, or a lower treaty rate, usually collected by withholding

For instance, non-resident aliens who have earned ECI would use Form 1040-NR. Non-residents whose income consists solely of FDAP income that has already been entirely withheld from their pay may have nothing to file; nevertheless, there are advantages in filing a tax return in order to receive any refunds or treaty benefits.

There is a tax treaty between the United States and Bangladesh. Whether the treaty will reduce your withholding is dependent on the nature of the income and the stipulations of the treaty. In most cases, the payer will request you to complete Form W-8BEN.

Form 5472 and Pro Forma Form 1120: The Filing Most Founders Actually Need

Here is the filing that catches most Bangladeshi LLC owners by surprise. A US single-member LLC owned by a foreign person has no income tax return of its own, but the IRS requires it to file a pro forma Form 1120 with Form 5472 attached for any year in which it had a reportable transaction with its foreign owner or a related party.

Transactions to be reported are broader than most founders would expect. Transactions that include depositing cash to the LLC’s bank account, withdrawing cash from the LLC’s bank account, and paying the LLC’s bills on behalf of the owner may be included. For this reason, almost every foreign-owned LLC that engages in business activities during the year will need to file Form 5472.

The key points to remember:

• Form 5472 is an information return, not a tax return. It discloses the transactions made between the LLC and its foreign owner to the IRS.
• It is filed by the LLC, which is why it uses the LLC’s EIN, explaining the importance of obtaining an EIN.
• It is separate from Form 1040-NR. The filing of one form does not cover the filing of the other.
• It is required irrespective of whether the LLC earned any income as long as there were reportable transactions.
• The failure to file the Form 5472 comes with huge penalties, which makes it much more costly to neglect than filing a tax return personally.

For many Bangladeshis, Form 5472 with the pro forma Form 1120 is the only annual filing requirement to US federal authorities.

Situations When Founders from Bangladesh Should File Forms

Different business models generate different results. This is an illustration and should not be used as specific advice on your situation.

Freelancer or agency providing services from Bangladesh. Service performed in Bangladesh to clients globally is usually considered foreign sourced income. The founder typically does not have a Form 1040-NR obligation but the LLC will need to file Form 5472 along with the pro forma Form 1120.

E-commerce business having inventory in US. Holding inventory in US warehouses and serving customers in US may be considered a US trade or business and thus, result in effectively connected income and Form 1040-NR filing obligation among other issues.

SaaS or other software products. Depends on where the service is being provided, customers located, income characterization and other factors. Digital income needs analysis before drawing a conclusion.

Dropshipper. It will depend on the jurisdiction where the goods are kept, the target customers, and the company structure. Evaluate each scenario rather than making assumptions.

Founder frequently visiting the US. Visiting the US can lead to US source income if you provide services there; multiple visits may even impact your residency.

Founder with US rental and investment income. These types of income fall under specific categories that include FDAP and other tax regulations.

Important Tax Deadlines to Consider

Deadlines differ between the personal return and the LLC’s information return, so track them separately.

Filing	Who Files	Typical Deadline	Extension
Form 1040-NR	The nonresident owner	April 15 if wages were subject to US withholding or the owner has a US office, otherwise June 15	Available through the IRS extension process
Form 5472 with pro forma Form 1120	The foreign-owned LLC	April 15 for a calendar-year LLC	Six months through Form 7004

Since IRS requirements may vary from year to year, please consult the updated filing instructions for each specific form. Late filing of Form 1040-NR will also limit your tax benefits since this type of return should usually be filed during the limited period after the tax filing deadline for allowing deductions and credits.

Documents Required to File Form 1040-NR

Here is the list of items needed for completing your nonresident tax return:

• A Taxpayer Identification Number: This document should include either an SSN or ITIN, depending on the case. It is quite hard for a typical Bangladesh founder to obtain the SSN, so he applies for the ITIN by completing Form W-7 along with his first tax return
• Passport and other identification documents used to complete Form W-7
• Evidence of income from the U.S., e.g. invoices, bank statements and Forms 1042-S or 1099, if you got any
• Detailed business-related expenses connected with income from the U.S
• The LLC’s EIN and formation documents.
• Evidence of presence in the U.S. during the tax period, if you traveled to the U.S.
• Treaty documentation: Form W-8BEN or statements supporting this form.

Apply for the ITIN as soon as possible because it will take some time for IRS to process your application and the time frame may influence your deadline for filing taxes.

Penalties and Consequences of Filing the Wrong Form

The main mistakes made by the foreign LLC owners during tax filing include.

• Failure to submit the Form 5472. The IRS fine for not filing this form begins from a significant fee per form per year and may be increased in case of continued violation after the notice was sent.
• Not filing the required Form 1040-NR. You will pay the penalties and interests as well as will be deprived of the deductions.
• Sending Form 1040 while being a nonresident. You might declare worldwide income of the entity that does not fall into US taxing jurisdiction.
• Incorrect taxpayer ID.

Because of these risks, it is better to confirm your filing position early than to fix it after an IRS notice arrives.

Common Errors Made by Founders from Bangladesh

1. Assuming that a US LLC requires a filing of Form 1040. Nonresident aliens usually file Form 1040-NR upon need to file, rather than Form 1040.
2. Neglecting Form 5472 since the LLC did not generate any income. Form 5472 filing requirement depends on the reportable transaction, and not profit.
3. Confusion between the two deadlines for filing of tax returns for the LLC and for the owner.
4. Filing foreign income in Form 1040-NR. Non-residents usually file US-source and effectively connected income in Form 1040-NR, not total income.
5. Starting the ITIN application too late, then failing to meet filing deadlines.
6. Assuming that income earned in Bangladesh is never subject to US taxation. Whether work was performed is just one aspect of the test, which may change depending on whether there is US inventory or US office.
7. Assuming that the EIN is used in lieu of your taxpayer number. The EIN is for the business while ITIN/SSN is for you personally.
8. Relying on online resources without a professional’s review.

Frequently Asked Questions

Final Words

It is not a choice to go for either IRS Form 1040 or 1040-NR. Rather, it is about the tax status in the eyes of the IRS as a resident or nonresident alien and the type of income you receive. A Bangladeshi founder residing in Bangladesh can be a nonresident, use Form 1040-NR due to a specific requirement and does not even have any need for a personal return.

While the founders will have no choice but to prepare the annual return for the LLC, which consists of Form 5472 with the pro forma Form 1120, independent of their personal tax return. Just ensure that you have the EIN number, maintain record of your US days and get yourself familiarized with the tax filing requirements annually, as there may be changes every year. Finset Formation is here to assist you to form your US company.
