FAQs

Do I need to file a Delaware Franchise Tax & Annual Report?

If you have a Delaware C-Corp which was in existence during any calendar tax year (1st January to 31st December), then yes you must file the Annual Report and pay the Delaware Franchise Tax. This is going to cost you a minimum of $400 tax + $50 government filing fee, and possibly much more if you've raised in the millions.

Do I need to file a Form 7004?

Your chosen tax year dates are normally Jan-Dec unless you specific asked for it to be something else in your EIN application (SS-4). - for example Apr-Mar is common for those with Indian subsidiaries to match the underlying India tax year. You can check your chosen US dates in your SS-4 (field 12)or your EIN issuance letter (paragraph 3). Depending on your chosen tax year dates, and only if you want a 6-month extension to your corporate tax deadline, you will need to file the Form 7004 either by 15th April (if your tax year is Jan-Dec) or 15th Jul (if your tax year is Mar-Apr). This buys you a 6 month breather.

When is the deadline to file Form 7004 for C Corporations?

C Corporations must file Form 7004 on or before the original deadline of their tax return Form 1120, which is by the 15th day of the 4th month after the taxable year ends.

The deadline for C-Corporations following the calendar tax year is April 18, 2023.

What are the penalties for filing Form 7004 Late?

Suppose you fail to file a 7004 tax extension or tax return within the appropriate deadline (March 15, 2023, for S-corporations and partnerships and April 18, 2023, for corporations and other businesses). In that case, the IRS will charge interest and penalties on any unpaid Federal taxes.

If you do not file and owe taxes, the failure-to-file penalty is 5% per month (up to 5 months) of the amount due. If your return is over 60 days late, you may be subject to a $135 minimum penalty. The IRS will also impose a failure-to-pay penalty of 0.5% per month (up to 25%) of the amount due if you file a return or extension but don’t pay all your taxes on time.

What is Delaware Franchise Tax?

The Delaware Franchise Tax is an annual tax imposed on businesses incorporated in Delaware or have a presence there. It is not a tax on income but on the privilege of conducting business in Delaware.

What is a Form 1120 in Delaware?

Form 1120 is a crucial tax document utilized by corporations in the United States to disclose their income, gains, losses, deductions, and credits for federal income tax goals. In Delaware, corporations are expected to submit Form 1120 if they are operating within the state or have obtained income from sources within its boundaries.

What does Delaware C Corp mean?

A Delaware C Corporation (C Corp) is a type of business entity formed under the laws of Delaware and is taxed separately from its owners. A C Corp is considered a separate legal entity from its shareholders, meaning it can enter into contracts, own assets, and conduct business in its name.

What is Delaware C corporation tax?

How can I get IRS Form 1099?

Can I e-file Form 1099 with the IRS?

Who is required to submit Tax Form 1120?

Regardless of taxable income, every US-based domestic corporation must file tax Form 1120. 

The following entities fall under the obligation to file tax Form 1120:

  1. Businesses opting for corporate taxation. These businesses must also complete Form 8832 and include a copy of Form 1120.
  2. Limited liability companies (LLCs). LLCs file Form 1120 only if they've chosen corporate taxation. Partnership LLCs use Form 1065, while single-member LLCs typically file taxes through the owner's personal federal tax return.
  3. Farming corporations. They are required to file Form 1120 to report their income/losses.
  4. Corporations with an ownership interest in a FASIT (Financial Asset Securitization Investment Trust).
  5. Foreign-owned domestic disregarded entities. If a foreign entity owns 100 percent of a domestic disregarded entity (D.E.), the D.E. is treated as separate from its foreign owner. The foreign entity must file Form 1120 and attach Form 5472.

Additionally, some types of corporations may need to complete additional forms, such as Form 1120 (Schedule N), for foreign operations in the U.S. Small corporations might not be required to fill out these additional forms. You can locate them by searching for "Form 1120" using the IRS Forms and Publications tool.

What sets apart a 1040 from an 1120?

Individuals employ Form 1040 to file personal income taxes, whereas C corporations utilise Form 1120 for corporate tax returns. The primary distinction lies in the taxpayer type: 1040 is for individuals, and 1120 is for corporations.

Which organisations are exempt?

The IRS grants tax-exempt status to specific organisations, such as:

  1. Charitable organisations
  2. Social welfare organisations
  3. Social clubs
  4. Trade associations
  5. Labor organisations
  6. Veterans' organisations
  7. Political organisations

The IRS maintains a comprehensive list of tax-exempt organisations, available here. These organisations are required to submit an information return, which may include Form 990, Form 990-EZ, and Form 990-PF.

What happens if errors are made during the completion of Form 1120?

In such cases, you need to rectify the mistake by amending the form. Utilise Form 1120X, the Amended U.S. Corporation Income Tax Return, for this purpose. Form 1120X must be submitted within three years from the original return.

To complete Form 1120X, you'll need the following information:

  1. Business name
  2. Explanation of changes
  3. Business address
  4. Details on payments and credits
  5. Data on income and deductions
  6. Tax amount due or overpayment
  7. Employer Identification Number (EIN)
  8. Signature
What are the penalties for a business that doesn't e-file IRS forms in 2024?

If a business fails to e-file information returns like Forms W-2 and 1099-series when required, it may face penalties as outlined in IRC Section 6721. These penalties can be imposed for not filing electronically and for late filing or submitting returns with incorrect information.

In 2023, the potential penalty can reach up to $310 for each return, with a yearly cap of $3,783,000. However, for smaller businesses with annual gross receipts not exceeding $5 million, the maximum penalty is limited to $1,261,000. These penalty amounts are subject to annual adjustments based on indexing.

Additionally, hardship waivers are available for those who would encounter significant difficulties meeting the e-filing requirements.

What is the IRS electronic mandate?

The Internal Revenue Service (IRS) has introduced a significant update to its electronic filing requirements, effective for the 2023 tax year and onwards (to be filed in 2024). This new mandate stipulates that businesses filing ten or more information returns within a calendar year are obliged to submit these returns electronically. This marks a substantial change from the previous regulation, which set the electronic filing requirement at over 250 annual information returns.

Issued in February 2023, the updated IRS regulations encompass various information return types, including forms such as 1099s and W-2s. Under this new rule, businesses are required to aggregate the total number of all return types to determine if they meet or exceed the ten-return threshold. For instance, a company that needs to file two Form W-2s and eight Form 1099-NECs would have to file all of these returns electronically, as the combined total crosses the ten-return limit.

The mandate is quite inclusive, with few exceptions. It applies to almost all returns if their cumulative number exceeds ten. This regulation significantly impacts how businesses manage and file their information returns, especially those dealing with independent contractors' payments.

How will your company adapt its processes for managing and filing 1099-NEC forms to comply with the new requirements?

The updated IRS electronic filing mandate has significant implications for businesses employing independent contractors. While many companies are accustomed to electronically filing W-2 forms, the inclusion of 1099-NEC forms, typically used for freelancers and 1099 workers, into this process is a new requirement. Businesses with many independent contractors must now develop standardized procedures for filing 1099-NEC forms to maintain organized records, including tax verifications and invoices, for smooth filing at year-end.

The change from a 250-return threshold to just ten is considerable, affecting many businesses that previously relied on manual filing methods.

This oversight can lead to compliance risks and unregulated spending. With the new mandate, it becomes crucial for businesses working with independent contractors to maintain a comprehensive overview of all 1099-NEC forms required for end-of-year filing.

To adapt, companies may need to assign specific roles, possibly within human resources, to manage independent contractor engagements. This would ensure consistent onboarding and payment processes across the organization, facilitating accurate reporting at the end of the year.

Additionally, implementing automated and centralized systems could significantly reduce administrative workload and the likelihood of manual errors.
