If you run an online business, you may have to deal with W-9 forms from your clients or vendors. A W-9 form is a request for your taxpayer identification number (TIN) and certification that you are not subject to backup withholding. You need to provide a W-9 form to any person or entity that pays you more than $600 in a calendar year for services or goods.
But what if you operate your online business in different states? Do you need to fill out a separate W-9 form for each state? How do you handle the tax implications of working remotely across state lines? Here are some tips and guidelines to help you navigate this situation.
Do You Need a Separate W-9 Form for Each State?
The short answer is no. You only need to fill out one W-9 form for your online business, regardless of how many states you work in or sell to. The W-9 form is a federal form, not a state form, so it does not vary by state. You can use the same W-9 form for all your clients and vendors, as long as your information does not change.
However, you may need to provide additional information or forms to some states, depending on their tax rules and requirements. For example, some states may require you to register as a foreign entity, obtain a sales tax permit, or file a nonresident income tax return if you have economic nexus in that state. Economic nexus is a term that refers to having a certain amount of sales or transactions in a state, which creates a tax obligation for your online business.
To determine if you have economic nexus in a state, you need to check the specific thresholds and criteria for each state where you do business. These vary widely by state, and some states do not have economic nexus laws at all. You can use this online sales tax guide to find out the rules for each state.
How to Handle Sales Tax for Online Business in Different States
Sales tax is a tax imposed by state and local governments on the sale of goods and services. As an online business owner, you may have to collect and remit sales tax to the states where you have sales tax nexus. Sales tax nexus is similar to economic nexus, but it also includes other factors that create a physical presence or connection to a state, such as having employees, inventory, or affiliates in that state.
The first step to handle sales tax for your online business is to determine where you have sales tax nexus. You can use this sales tax nexus quiz to help you with this. The next step is to register for a sales tax permit in each state where you have nexus. You can find the links to each state’s registration page here. The third step is to collect sales tax from your customers based on the origin or destination of the sale. Origin-based sales tax means you charge the sales tax rate of your location, while destination-based sales tax means you charge the sales tax rate of your customer’s location. The final step is to file and pay sales tax to each state where you have nexus, according to their filing frequency and deadlines.
Here is an example of how to handle sales tax for online business in different states:
| State | Sales Tax Nexus | Sales Tax Permit | Sales Tax Rate | Sales Tax Filing |
|---|---|---|---|---|
| California | Yes, because you have inventory in a warehouse in California | Yes, you need to register with the California Department of Tax and Fee Administration | Destination-based, you need to charge the sales tax rate of your customer’s location in California | Quarterly, you need to file and pay sales tax by the last day of the month following the end of the quarter |
| New York | Yes, because you have more than $500,000 of sales and 100 transactions in New York in the previous four quarters | Yes, you need to register with the New York Department of Taxation and Finance | Destination-based, you need to charge the sales tax rate of your customer’s location in New York | Monthly, you need to file and pay sales tax by the 20th day of the month following the end of the month |
| Texas | No, because you do not have any physical presence or economic nexus in Texas | No, you do not need to register or collect sales tax in Texas | N/A | N/A |
How to Handle Income Tax for Online Business in Different States
Income tax is a tax imposed by federal, state, and local governments on your income from your online business. As an online business owner, you have to file and pay income tax to the federal government and your home state, where your business is based. You may also have to file and pay income tax to other states where you have income tax nexus. Income tax nexus is similar to sales tax nexus, but it also includes other factors that create a source of income or connection to a state, such as having customers, contracts, or employees in that state.
The first step to handle income tax for your online business is to determine where you have income tax nexus. You can use this guide to help you with this. The next step is to allocate your income to each state where you have nexus, based on their apportionment formulas. Apportionment formulas are methods that states use to divide your income among the states where you do business, based on factors such as sales, payroll, or property. The third step is to file and pay income tax to each state where you have nexus, according to their filing frequency and deadlines.
Here is an example of how to handle income tax for online business in different states:
| State | Income Tax Nexus | Income Allocation | Income Tax Rate | Income Tax Filing |
|---|---|---|---|---|
| California | Yes, because your business is based in California | 100% of your income is allocated to California | 8.84% for corporations, or 13.3% for individuals | Annually, you need to file and pay income tax by April 15 |
| New York | Yes, because you have more than $1 million of sales in New York in the previous year | 10% of your income is allocated to New York, based on the sales factor | 6.5% for corporations, or 8.82% for individuals | Annually, you need to file and pay income tax by April 15 |
| Texas | No, because Texas does not have an income tax | N/A | N/A | N/A |
