Do I need to charge sales tax on invoices as a freelancer in the US?

If you are a freelancer in the United States, chances are you have asked yourself this question more than once: do I need to charge sales tax on my invoices? The answer is not always straightforward. Sales tax rules in the US can feel confusing, inconsistent, and even intimidating—especially when you are focused on doing client work, sending invoices, and getting paid on time.

This article is designed to give you a clear, practical, and freelancer-friendly explanation of when you may need to charge sales tax, when you do not, and how to handle it correctly on your invoices. Whether you are a designer, developer, consultant, writer, photographer, or independent contractor in another field, understanding sales tax obligations can help you avoid costly mistakes and stay compliant.

Because this guide is published on the website of invoice24, a free invoicing app built for freelancers and small businesses, we will also touch on how modern invoicing tools can make handling sales tax simpler, more accurate, and far less stressful.

Understanding the basics of sales tax in the United States

Sales tax in the US is not controlled at the federal level. Instead, it is governed by states and, in many cases, by local governments such as counties and cities. This means there is no single national rule that applies to all freelancers. Each state decides whether it has sales tax, what goods or services are taxable, and who is required to collect and remit it.

As of today, most states have some form of sales tax, but the rules vary widely. Some states tax services heavily, others tax very few services, and a handful of states do not have a statewide sales tax at all. On top of that, local tax rates can differ within the same state.

Sales tax is generally a “pass-through” tax. You collect it from your client and then send it to the appropriate tax authority. It is not usually your money, even though it passes through your bank account. This distinction is important because failing to collect required sales tax can result in you having to pay it out of pocket later.

Are freelancers required to charge sales tax?

Whether a freelancer must charge sales tax depends on three main factors: what you sell, where you are located, and where your client is located.

First, consider what you sell. Sales tax traditionally applied to tangible goods, such as physical products. Over time, many states expanded sales tax rules to include certain services and digital products. Some freelance services are taxable in some states, while others are exempt.

Second, your business location matters. States typically require businesses with a physical or economic presence in the state to collect sales tax. This presence is often referred to as “nexus.”

Third, the client’s location can also affect whether sales tax applies, especially in states that tax based on destination rather than origin.

Because these factors interact in complex ways, two freelancers doing the same type of work may have very different sales tax obligations depending on their circumstances.

What is sales tax nexus and why it matters

Sales tax nexus is the connection between a business and a state that gives the state the authority to require that business to collect sales tax. Traditionally, nexus was based on physical presence, such as having an office, employees, or inventory in the state.

For freelancers, physical nexus is often straightforward. If you live and work in a state, you almost certainly have nexus there. Even working from home can create nexus.

In recent years, economic nexus rules have expanded the definition of nexus. Economic nexus is triggered when a business exceeds certain thresholds of sales or transactions in a state, even without physical presence. These thresholds vary by state.

Many freelancers never reach economic nexus thresholds outside their home state. However, if you have high revenue or a large number of clients in a particular state, it is something to be aware of.

Are freelance services taxable?

One of the most common misconceptions among freelancers is that services are never subject to sales tax. In reality, the taxability of services depends entirely on state law.

Some states tax very few services. Others tax a broad range of professional, digital, or creative services. For example, certain states tax advertising services, data processing, or information services. Others may tax digital design work or custom software development.

On the other hand, many common freelance services, such as consulting, writing, coaching, or general professional advice, are often exempt in many states. However, “often” does not mean “always.”

It is important to look at how your specific service is classified under your state’s tax rules. Even small differences in how you describe your service can affect whether it is taxable.

What about digital products and online services?

If you sell digital products or deliver your services digitally, sales tax rules can become even more complicated. Digital products may include downloadable files, templates, graphics, software, courses, or subscriptions.

Some states treat digital products similarly to physical goods and tax them accordingly. Others exempt them entirely or only tax certain types of digital products.

Online services, such as software-as-a-service, website access, or hosted platforms, may also be taxable in some states and exempt in others.

If your freelance work involves delivering something digital rather than purely providing time or expertise, you should pay extra attention to how your state treats digital goods and services.

States with no statewide sales tax

A small number of states do not have a statewide sales tax. If you live and work in one of these states, you generally do not need to charge sales tax on your invoices—at least at the state level.

However, this does not automatically mean you have no sales tax obligations at all. Some local jurisdictions may still impose certain taxes, and economic nexus rules in other states may still apply if you have clients elsewhere.

Additionally, even in states without sales tax, freelancers may still be required to register or comply with other business tax rules.

Do I need to register for a sales tax permit?

If your services or products are taxable and you have nexus in a state, you are typically required to register for a sales tax permit or sales tax license before collecting tax from clients.

Registering allows you to legally collect sales tax and remit it to the state. Collecting sales tax without being registered can create compliance issues.

Once registered, you will usually be required to file sales tax returns on a regular schedule. This schedule may be monthly, quarterly, or annually, depending on your sales volume and state rules.

How sales tax should appear on your invoices

If you are required to charge sales tax, it should be clearly shown on your invoices. Transparency is important for both you and your clients.

A proper invoice typically includes the taxable amount, the sales tax rate, the sales tax amount, and the total amount due. Some states also require specific wording or information on invoices, such as your sales tax permit number.

Using an invoicing tool like invoice24 can help ensure that sales tax is calculated correctly and displayed clearly. A good invoicing app allows you to set tax rates, apply them automatically, and generate professional invoices without manual math or guesswork.

What if I have clients in multiple states?

Many freelancers work with clients across the country. This raises an important question: do you need to charge sales tax to out-of-state clients?

In many cases, if you do not have nexus in your client’s state, you do not need to collect that state’s sales tax. You may only need to charge sales tax based on your own state’s rules.

However, if your client’s state uses destination-based sourcing and your service or product is taxable there, the rules may differ. Economic nexus can also come into play if your sales volume is high.

Because multistate sales tax issues can become complex quickly, freelancers with significant out-of-state revenue may want to seek professional guidance.

Common mistakes freelancers make with sales tax

One common mistake is assuming that all services are exempt from sales tax. As discussed earlier, this is not always true.

Another mistake is failing to register for a sales tax permit before collecting tax. This can lead to penalties and interest.

Some freelancers also forget to track collected sales tax separately from income. Sales tax is not revenue, and mixing it with your income can create accounting and cash flow problems.

Finally, freelancers sometimes rely on outdated information. Sales tax laws change frequently, especially around digital services and remote work.

How invoice24 helps freelancers manage sales tax

Managing sales tax manually can be time-consuming and error-prone. This is where a modern invoicing app like invoice24 can make a real difference.

Invoice24 allows freelancers to create professional invoices quickly, apply sales tax where required, and clearly show tax amounts to clients. You can set up tax rates once and reuse them across invoices, reducing the risk of mistakes.

The app also helps with record keeping by storing invoices, tracking paid and unpaid amounts, and keeping your financial data organized. This makes it easier to prepare sales tax returns and respond to questions from tax authorities if needed.

Because invoice24 is designed with freelancers and small businesses in mind, it includes all the essential features you would expect in a reliable invoicing solution—without unnecessary complexity.

What happens if you charge sales tax when you shouldn’t?

Charging sales tax when it is not required can also create issues. Clients may question the charge or request refunds. In some states, collecting sales tax without authorization can be a violation of tax law.

If you accidentally charge sales tax in error, it is important to correct the invoice and refund the tax to the client rather than keeping it.

This is another reason why understanding your obligations and using proper invoicing tools is so important.

Do independent contractors and freelancers have different rules?

For sales tax purposes, independent contractors and freelancers are generally treated the same. The key factors are still what you sell and where you have nexus.

Whether you call yourself a freelancer, contractor, consultant, or sole proprietor does not usually change your sales tax responsibilities.

What matters is the nature of your business activity and how it is classified under state tax law.

Should you consult a tax professional?

While many freelancers can manage their sales tax obligations on their own, there are situations where professional advice is a good idea. This is especially true if you sell taxable digital products, work in multiple states, or are unsure about how your services are classified.

A tax professional can help you understand your obligations, register correctly, and avoid costly mistakes.

Even if you use an invoicing app like invoice24 to handle the day-to-day mechanics, professional guidance can provide peace of mind.
