Whether you are brand new to freelancing or have been sending invoices for years, tax questions come up constantly. Do you add a tax line? Which rate? What if your client is in a different country?
The short answer depends on where you live, what you sell, and who your client is. Our free invoice generator handles tax lines automatically — no signup, 100% in your browser — so you can stop guessing and start getting paid correctly.
This guide unpacks the most common freelance tax scenarios in plain language, with links to the official sources so you can verify everything yourself.
The Two Types of Tax Freelancers Confuse
Most freelancers are actually thinking about two completely different taxes when they ask this question:
-
Sales tax / VAT / GST — a tax you collect from your client on behalf of the government, then remit. You are acting as the tax collector. It appears as a line item on your invoice.
-
Self-employment tax — a tax you pay yourself on your net profit at the end of the year. Your clients never see or pay this. It does not appear on invoices.
Understanding which is which changes everything about how you handle your invoicing.
Sales Tax on Freelance Services in the United States
The General Rule: Most Services Are Not Taxed
In most US states, sales tax applies to physical goods, not services. If you are a freelance writer, developer, designer, consultant, or photographer, you generally do not add sales tax to your invoices.
There are meaningful exceptions.
States That Tax Some Services
A handful of states impose tax on certain services:
- Hawaii taxes nearly all services under its General Excise Tax
- New Mexico imposes a Gross Receipts Tax on services
- South Dakota taxes a broad range of professional services
- Texas taxes certain data processing and digital services
- New York taxes some digital services and certain professional services
The rules are also different if you sell digital products — templates, fonts, stock photos, software licenses. Many states that exempt pure services still tax digital goods. Check your state's department of revenue for the specific rules that apply to your work.
Nexus: Why Your Location Matters
Sales tax is governed by the concept of nexus — your economic or physical connection to a state. For most solo freelancers, you only have nexus in your home state. That means you generally only need to worry about one set of rules unless you have significant operations in multiple states.
If you are unsure whether your specific services are taxable in your state, your state's department of revenue website is the authoritative source. A CPA who works with freelancers is worth consulting if your situation is complex.
Self-Employment Tax: What You Pay, Not What You Collect
Self-employment tax is entirely separate from what you charge clients. It is not a line on your invoice — it comes out of your earnings when you file your annual tax return.
The IRS sets the self-employment tax rate at 15.3% of your net self-employment income — 12.4% for Social Security and 2.9% for Medicare. You can deduct half of self-employment tax when calculating your adjusted gross income, which reduces the effective cost somewhat.
The key point: never add self-employment tax to a client invoice. It is your tax liability, not theirs.
VAT for Freelancers in the UK and EU
If you are based in the UK or EU, Value Added Tax (VAT) replaces sales tax.
United Kingdom
In the UK, you are not required to register for VAT until your taxable turnover crosses the registration threshold set by HMRC. Until you cross that threshold, you do not charge VAT and cannot reclaim VAT on purchases.
Once registered, the standard VAT rate is currently 20%, and you must:
- Add a VAT line to every qualifying invoice
- Include your VAT registration number on every invoice
- Submit regular VAT returns to HMRC
Some freelancers choose to register voluntarily before hitting the threshold if they have significant VAT-able expenses — it lets you reclaim that VAT back.
European Union
In the EU, each member state sets its own VAT rate (typically 19–25%). The rules for when you must register vary by country, so check your local tax authority.
For cross-border B2B work (freelancer in one EU country invoicing a VAT-registered business in another), the reverse charge mechanism often applies. This means the client — not you — accounts for the VAT. You still need to include specific wording on the invoice such as "VAT: Reverse charge applies" and your EU VAT number.
For cross-border B2C work (invoicing individual consumers in other EU countries), the rules are more complex and depend on your total EU sales volume.
GST for Freelancers in Canada and Australia
Canada
The Canada Revenue Agency (CRA) requires you to register for GST/HST once your total taxable revenues exceed CAD $30,000 in a single calendar quarter, or in four consecutive calendar quarters.
Below that threshold you are a "small supplier" — registration is optional. Once you register, you must charge GST (or HST depending on your province), include your Business Number on invoices, and file regular returns.
Australia
The Australian Taxation Office (ATO) requires GST registration when your annual turnover reaches AUD $75,000 or more (AUD $150,000 for non-profit organisations).
The standard GST rate is 10%. Once registered, add GST to your invoices, include your ABN, and lodge regular Business Activity Statements.
B2B vs. B2C: Why Your Client Type Changes the Rules
US: Tax-Exempt Certificates
Many US businesses will provide a resale certificate or tax-exempt certificate if your services would otherwise be taxable in your state. When a client provides this documentation, you do not charge them sales tax even if the service is normally taxable. Always request the certificate in writing and keep it on file.
UK/EU: Reverse Charge
When invoicing VAT-registered businesses in other EU countries or the UK (cross-border B2B), the reverse charge mechanism shifts the VAT obligation to your client. Your invoice shows the net amount with a note that reverse charge applies — you do not collect or remit VAT on that transaction.
All Regions: Get It in Writing
Whether it is a tax-exempt certificate, a VAT number, or a GST business number, document your client's tax status before you start work. It protects you if questions arise later.
How to Add a Tax Line to Your Invoice
Regardless of which tax applies, adding it to your invoice is straightforward. Every professional invoice that involves tax should show:
- Net amount — the price before tax
- Tax rate and amount — for example, "GST 10% — $45.00"
- Gross total — the amount the client actually pays
- Your tax registration number (required outside the US once registered)
Our free invoice generator handles all of this automatically. Set a tax percentage, and the tool calculates the tax amount and gross total instantly. Download a clean PDF in seconds — no account required, no data sent to any server.

Frequently Asked Questions
Do I charge tax if my client is in a different US state?
For most freelancers selling services, no. Sales tax nexus for solo service providers typically only applies in your home state. If you sell software, digital products, or physical goods to clients in other states, the rules are more complex — consult a CPA.
Should I register for VAT or GST before I hit the threshold?
Not necessarily. Voluntary registration adds compliance overhead (regular returns, record-keeping). It makes financial sense if you have significant VAT-able expenses you want to reclaim. Most freelancers wait until they are close to the mandatory threshold.
Can I retroactively add tax to an invoice I already sent?
No. Once issued, do not alter an existing invoice. If you discover you should have been charging tax, issue a corrected invoice and discuss the adjustment with your client. Getting professional advice in this situation is worthwhile.
Do I need a tax number on my invoice?
In the US, no federal requirement applies. In the UK, EU, Canada, and Australia, once you are registered for VAT or GST, your registration number must appear on every invoice you issue. It is a legal requirement, not optional.
What is the difference between tax-exclusive and tax-inclusive pricing?
- Tax-exclusive: The stated price does not include tax. Tax is added on top. Example: $500 net + 20% VAT = $600 total.
- Tax-inclusive: The stated price already includes tax. You must calculate the tax portion. Example: $600 total at 20% VAT contains $100 of VAT.
Most B2B invoices use tax-exclusive pricing because it makes the tax amount transparent.
I'm a US freelancer — why does my invoice template have a tax field if I probably don't need it?
Because some US freelancers do need it — those in states that tax services, those selling digital products, and those working with international clients. The field is there when you need it and invisible when you don't.
