Illinois Sales Tax: Small Business Guide on What You Need to Know

The practical guide for sellers, virtual businesses and bookkeepers

It is important for business owners, executives and other professionals to have a general understanding of when Illinois sales tax might apply to their business transactions. This guide gives an overview of the tax and its fundamental principles, who needs to register and collect it as well as common deductions, how jurisdictional rates impact the total amount of money collected, and what you should do in order to remain in compliance. Whether you work in a physical store, from a distance or oversee accounts for multiple locations, the following four principles will be useful to define responsibilities and reduce risk.

How Illinois sales taxes are calculated

Illinois has a state sales tax that is applies other towards the cost of things an Illinois than most States sale are transported to keep retail store. Counties, cities and special districts also may add sales taxes on top of the state base rate. The outcome is a combined rate that differs by location. And for merchants, the important thing to remember is that the full rate applied at the point of sale will be equal to the state rate plus any local rates due based on where the customer is.

What is taxable

Retail sales of tangible personal property are usually subject to tax. There are still many services that aren’t subject to sales tax, but some services are taxable based on the nature of the service and how it is sold. Examples of items that are usually taxrated include food served for consumption on the premises, some applicability to digital products and sales of tangible personal property. Hundreds of staple grocery items and most prescription medications are often exempt, however. Since categories differ, sellers should determine that each item or service they sell is taxable.

Nexus and remote sellers

Historically, a physical presence in a state (a store, warehouse or employees) created sales tax nexus. Indeed, in this day and age, business activities that give rise to tax obligations now extend beyond the doors of physical facilities: sellers without a physical presence but who have some sort of economic nexus (such as volume of sales or number of transactions) required by a state are often mandated to register, collect and remit tax. Monitor Sales Into Illinois If you sell across the border into Illinois, monitor sales into the state so that you can see if you exceed any economic nexus threshold and have a collection responsibility.

Registration and collection responsibilities

Every business that needs to collect sales tax in Texas must first get a sales tax permit by registering with the TX Comptroller of Public Accounts before selling taxable goods or services. Registration results in an account number and filing periodicity. From there, you need to collect the correct total sales tax at checkout, provide required receipts when your customers ask for them, and keep up with transaction details and exemption certificates.

Filing and remittance schedules

The frequency at which you file returns and pay tax will normally be based on the amount of tax that you collect. Large volume collectors generally have to file on a monthly basis, mid-level ones quarterly and there is an annual filing available for smaller retailers. You are assigned a filing frequency & due date when you register, it is possible for your tax filing frequency to change if you have an increase in collections. Penalties and interest are typically assessed on late returns and payments, so keeping up with filing deadlines is critical.

Exemptions and certificates

Tax-free sales are those that the seller is able to keep appropriate documentation (i.e., resale certificates or exemption certificates from buyers). Receipt and retention of a valid certificate can provide a seller the benefit of not having to charge tax on a otherwise taxable transaction. But if the certificate is incorrect or unvalid, the seller could be held responsible for any unpaid tax. Design workflows for proofing, saving, and defensibly leveraging exemption documentation.

Rates of local and special district taxes

Additional taxes are imposed by local governments and special districts for addresses in some areas, and the combined sales tax rate can reach nearly 10 percent in parts of the state. This also means two storefronts near each other might have different combined rates. Setting the right rate can be a matter of customer location — in many cases, this will be the point-of-delivery for shipped merchandise or the point-of-sale for face-to-face sales. Stay updated on changes to local rates, special assessments that might impact your total tax bill.

Marketplace sales and intermediaries

Marketplace facilitator In many cases, tax may be collected and remitted by the marketplace facilitator on behalf of third-party sellers. Marketplace providers, check now to see whether marketplace is the collector and keep records in case of auditSubsequent periodic collectionEither party may start collecting at any time….Sellers using marketplaces should confirm if the marketplace collects and also maintain documentation supporting their tax reporting and remittance, even if someone else is doing that.

Recordkeeping and audit readiness

Accurate, complete records are a seller’s best protection in an audit. Retain sales invoices, exemption certificates, return filings, payment confirmations and supporting calculations for the rate used. Compare point of sale total to returns and remittances on an ongoing basis. Implement checks and balances to maintain a reliable collection process and filing procedure.

Typical traps and how to avoid them
