tfn

A Tax File Number (TFN) is essential for making your new business capable of legally functioning. Starting a new business is a great experience, but it does consist of numerous mandatory actions.

One of the first things you will need to obtain on your business journey is a Tax File Number (TFN). This is a unique tax identification number that the Australian Taxation Office (ATO) issues so that your business can be appropriately identified for tax purposes. 

But what is a TFN, and why is it so important? If you’re a sole trader, a partnership, or in the process of creating a company, understanding your TFN role is vital.  

Securing your TFN in advance is one of the first things that you should do when beginning a new venture. It’s not just about complying with the law; it’s a means of setting up your business for success from the very start. So, let’s discuss everything that you need to know about your Tax File Number and how it is a fundamental part of your business experience!

What is a Tax File Number (TFN)?

A Tax File Number (TFN) is a nine-digit number assigned by the Australian Taxation Office (ATO) to individuals, businesses, and other organisations like companies, trusts, and superannuation funds. An identification number that simply serves as a marker for either your company or your private tax business. TFN exists solely for tax monitoring purposes which restrict any possible action you could take with it.

Key Features of a TFN:

  • Uniqueness: The Tax File Number operates independently for each person or business it issues because it remains personal to their identity. This prevents mixing up records with other taxpayers. The one-of-a-kind TFN system enables the ATO to manage appropriate records and monitor tax obligations effectively.
  • Nine-Digit Format: The TFN consists of nine digits that are assigned in a random pattern, and it is formatted as “nnn nnn nnn.”
  • Permanent: A TFN is permanent, so once issued, it’s yours for life (no matter if you change businesses, jobs, or personal details). You TFN registration is a critical step toward keeping legality and financial compliance in line, keeping financial management intact, and achieving long-term success. Only need to apply for a new TFN if you change your legal entity or structure (for instance, if you dissolve a company and establish a new one).

Why do New Businesses Require a TFN?

The Tax File Number functions as an essential element within your Australian taxation system. The Tax File Number functions as a critical tool for Australian fiscal management of new business in new enterprises.

A TFN maintains vital importance as a new business requirement as described below:

  1. Tax Compliance

One of the first requirements for any Australian firm or person is to obtain a Tax File Number (TFN). This number is needed by the Australian Taxation Office (ATO) in order to pay taxes, file tax returns, and record income. Without a TFN, businesses can face large fines and extra charges from the ATO.

  • Income Reporting: Every business must report its income to the ATO so it can be taxed. Your TFN is linked to your business’s tax profile, against which income tax assessments are made.
  • Tax Returns: At the conclusion of a fiscal year, businesses must file a tax return and a Business Activity Statement (BAS). To guarantee that the return is correctly connected to your business’s ATO account, it must be accompanied by the TFN.
  1. Business Growth

A Tax File Number (TFN) is essential for filing taxes and running your business smoothly. It is also needed when dealing with banks and financial institutions.

  • Creating a Bank Account for Your Business: Many banks will require your business TFN to open a business bank account. Banks require this because they must use the TFN to report any interest or earnings realised on your account. They also use it for tax purposes. Without a TFN for your business, it may have difficulty opening an account or face higher withholding taxes on any interest income.
  • Financial Transactions: In addition to the bank account, your TFN will be used in other financial transactions, including income from investments and applications for loans and financing.
  1. Employee Payroll and Superannuation

If your business hires employees, a TFN will be important to deal with employee payroll, tax, and superannuation payments. This is how:

  • PAYG Withholding: If you have staff, you are required to withhold Pay-As-You-Go (PAYG) tax from their wages. This involves withholding tax from their salary and paying it to the ATO. In order to do this right, you need to be aware of the TFN of each employee. Without this, you would not be able to withhold the right amount of tax.
  • Reporting to the ATO: You are required to report wages paid to employees, withholding tax, and superannuation contributions to the ATO on a regular basis. This necessitates having your TFN associated with your business in the ATO system.
  • Superannuation Contributions: Your TFN is required to manage superannuation (super) contributions for your employees. All super funds of employees use their TFN to account for contributions and ensure they are properly credited to their super fund. Without your employees’ TFNs, it could delay or complicate their super contributions.
  1. Claiming Tax Benefits, Deductions, and GST Registration

A TFN is needed for a new business to seek a range of tax concessions, offsets, and rebates from the ATO. It is also needed for the issue of Goods and Services Tax (GST) registration.

  • Tax Offsets and Deductions: All businesses qualify to claim tax offsets and deductions against certain expenses, such as equipment, office, or research and development. The TFN links your business to the claims so that all deductions are correctly processed and according to tax legislation.
  • GST Registration: If your turnover over the year exceeds the GST threshold (presently $75,000), you must register for GST. You will require a TFN for registration purposes. GST registration enables your business to reclaim GST on business purchases and charge GST on sales, which can help reduce costs and enhance cash flow.
  • Tax Refunds: If your business is entitled to a tax refund, the ATO will pay the amount using the TFN of the business.  
  1. Protecting Your Enterprise and Preventing Higher Withholding Taxes

In addition to ensuring the smoothest running of your company and simplifying taxes, a tax file number guarantees that your company does not pay more in taxes than it should. 

  • Higher Withholding Tax Without TFN: If you do not give your TFN when requested, banks and other financial institutions will withhold a higher rate of tax on dividends or interest your business has made. This is normally around 47%, much more than the usual rate. 
  • Privacy and Security: A TFN (Tax File Number) links your business’s tax records directly to the business, keeping everything separate from your personal tax matters and ensuring that your personal finances don’t interfere with your business operations.

What Are The Steps To Apply TFN for New Business?

Applying for a Tax File Number (TFN) for your new business is a significant step towards legalising it and keeping it in line with Australian taxation legislation.  It’s simple to apply and can be done online or on paper.

Here’s a simple, step-by-step guide to applying for a TFN:

Step 1: Check if You Require a TFN

Check if you require solo TFN or company TFN and apply according to it. Here are the features of TFN. 

  • Sole Traders & Partnerships: Depending upon whether you are a sole trader or partnership, you may be capable of utilising your own personal TFN in relation to reporting for tax purposes. 
  • Companies, Trusts, or Other Entities:There is different TFN for companies, trusts or other businesses.   

Step 2: Check required documents

  • Proof of Identity: This includes documents like your Australian passport, birth certificate, or driver’s license. These are required to verify your identity when applying for the TFN.
  • Business Registration Information: If so, ensure that your business is registered with the Australian Business Number (ABN) and Business Name Registration if you have a business operating under a special name. ABN and TFN are connected, so you will require an ABN for further processing.
  • Company Information: You might need to enter your Australian Company Number (ACN) and documents specific to your business.

Having the documents that are required at hand will prevent any delay and make the process easier.

Step 3: Lodge Online from the ATO Website

The easiest way to apply for a TFN for your business is through the Australian Taxation Office (ATO) website. Their online system is simple to use and works well for most businesses.

  • Sole Traders and Partnerships: If you’re a sole trader or in a partnership, you can apply for a TFN online through the ATO website. The process is simple—it will ask for your personal and business details and guide you through each step.
  • Companies and Other Organisations: When registering a company or other organisations, you can request a TFN at the time of registration and gaining your ABN. 

The best way to apply is on the ATO website, but a paper form is also available.

Step 4: Wait for Approval

After that, the ATO will process your application and assign your TFN within 28 days after receipt. While doing so, the ATO will check your details and assign a separate TFN for your company. Your TFN will then be sent to your nominated contact method e.g. post or email when it has been allocated.

Important Notes:

  • Keep your TFN confidential: After your TFN has been assigned, beware of to whom you provide it. Your TFN is confidential and should only be provided to authorised persons such as your accountant, the ATO, or your bank.
  • Record Keeping: Store your TFN securely in your business records. It is important for your future tax compliance and future business filings.

Connecting Your TFN with Your ABN

When establishing your business, it is also a good idea to register for an Australian Business Number (ABN). The ABN is required for the carrying out of business activities like invoicing and transacting with other businesses.

  • Linking TFN and ABN: As you go through registering for your ABN, you will be given the opportunity to link your TFN to your ABN. This simplifies your tax obligation because the ATO can then easily match your business’s tax information with your ABN and TFN.

Having an ABN and TFN is important to the success of your business in Australia and maintains your business current with tax legislation. It also allows you to lodge for GST and claim other tax deductions where appropriate.
