Homepage Blank St 556 Illinois Form
Outline

The ST-556 form, officially known as the Sales Tax Transaction Return, is a crucial document for businesses operating within Illinois that engage in the retail sale of certain items that require state titling or registration. This includes vehicles, watercraft, aircraft, trailers, and mobile homes. Any retailer selling these items must file the ST-556, even if no tax is due, to avoid potential penalties for unreported transactions. The form must be completed accurately, detailing the purchaser's information, the item sold, and any applicable exemptions or trade-ins. Notably, if an item is sold for lease, the seller must use a different form, specifically the ST-556-LSE. Filing can be done electronically through MyTax Illinois or via preprinted paper forms, which can be requested from the Illinois Department of Revenue. If errors occur while completing the form, sellers should void the incorrect document and retain it for their records rather than submitting it. The ST-556 form serves not only as a tax reporting tool but also as a means to ensure compliance with state regulations governing the sale of high-value items.

ST-556 Sales Tax Transaction Return Instructions (1) for Sales from Illinois Locations

General Information

Who must file Form ST-556?

If you sell items at retail in Illinois that are of the type that must be titled or registered by an agency of Illinois state government (i.e., vehicles, watercraft, aircraft, trailers, and mobile homes), you must report these sales on Form ST‑556, Sales Tax Transaction Return. Do not file Form ST‑556 if the item is being sold for lease. Instead, use Form ST‑556‑LSE, Transaction Return for Leases. Note, however, that you also must file Form ST‑556 if you are a leasing company selling such items at the end of a lease, but use the Form ST‑556 instructions for leasing companies selling at retail (ST‑556[2]) to assist you in completing the return properly.

Do I need to file Form ST-556 if no tax is due?

Yes. Anytime you sell an item at retail in Illinois that is of the type that must be titled or registered by an agency of Illinois state government, you must report the sale on Form ST‑556, regardless of whether you are reporting tax due. Failure to file Form ST‑556 as required subjects you to possible penalties for each transaction that goes unreported.

How can I file Form ST-556?

Form ST‑556 can be filed electronically using MyTax Illinois at mytax.illinois.gov. The Illinois Department of Revenue also issues preprinted paper forms in limited quantities. You can request preprinted returns by calling our Central Registration Division at 217 785-3707. You can also request preprinted returns using MyTax Illinois. Note that preprinted forms display information for each of your business locations. Related sales and use tax forms are available on our website at tax.illinois.gov.

What if I make a mistake while filling out a preprinted paper form?

If you make a mistake on a preprinted paper Form ST‑556, write “VOID” across the form. Keep the voided return in your records for at least 42 months. Do not send the form to us.

Specific Instructions

1 Enter the purchaser’s name and address

The purchaser’s name and address must be the same as the name and address on the application for title or registration. If there is more than one purchaser, be sure to enter each name.

2 Describe the item sold

Check the correct box (A – E) to show the type of item sold. If the type of item sold is not identified in boxes A – E, check box F and enter the type of item sold.

Check the correct box to show whether the item sold is new or used.

Next, enter the appropriate identification number for the item sold, such as a vehicle identification number (VIN) for vehicles, trailers, and mobile homes, a hull identification number (HIN) for watercraft, or (N) number for aircraft.

Finally, enter the year, make, body style, and model of the item sold.

Note: If you sold more than one type of item (e.g., a watercraft and a trailer) or more than one item of the same type (e.g., three motor vehicles) you generally must complete a separate Form ST‑556 for each item sold. If, however, you wish to report sales for resale or sales for use as rolling stock of more than one of the same type of item to the same purchaser with the same date of delivery, you may file Form ST‑556‑R, Resale and Rolling Stock Fleet Exemption Schedule, with a single Form ST‑556.

3 Enter the date of delivery

Enter the month, day, and year in which the purchaser took possession of the item.

Note: This return is due no later than 20 calendar days after the date of delivery.

4 Describe the trade-in, if any

If you did not claim a qualified trade‑in, skip this section and go to Section 5.

If you claimed a qualified trade‑in, enter the type of item traded in (e.g., automobile, truck, airplane, boat, trailer). Next, enter the appropriate identification number, year, make, body style, and model of the trade‑in.

What is a qualified trade-in? A qualified trade‑in is an item

that the purchaser gives you to reduce the selling price (in part or in full) of the item sold;

that you are allowed to subtract from the selling price; and

that you are in the business of selling.

You are “in the business of selling” a particular kind of item if you hold yourself out to the public as being engaged in (or habitually engage in) selling such items.

Example: You may claim the trade‑in of a boat on an auto if you are in the business of selling both boats and autos.

However, you may not claim the trade‑in of a boat on an auto if you are in the business of selling only autos.

Note: For sales made on or after January 1, 2020, up to and including December 31, 2021, for purposes of calculating your Sales Tax due, you cannot claim trade‑in credit exceeding $10,000 for any first division motor vehicle that was traded in during the sale being reported on Form ST‑556. For sales made on or after January 1, 2022, the $10,000 trade‑in credit limit no longer applies.

A. Sold to a nonresident purchaser

Check this box if you sold an item to a nonresident purchaser who is not an out‑of‑state dealer, and who took possession of the item in Illinois, and either

the purchaser transferred out‑of‑state license plates to the item sold.

If you issued a drive‑away permit, enter the drive‑away permit number and the two-letter state abbreviation of the purchaser’s state of residence in the space provided. If the purchaser transferred current out‑of‑state license plates to the item sold, enter the out‑of‑state license plate number and the two-letter state abbreviation in the space provided.

Non-Reciprocal Buyer

Exemption is determined by whether the purchaser’s state gives Illinois residents a nonresident purchaser exemption on their purchases of items that will be titled in Illinois. See ST‑58, Reciprocal ‑ Non‑Reciprocal Vehicle Tax Rate Chart, available on our website at tax.illinois.gov, and the instructions for Section 6, Line 4 below for more information.

Note: If you claim the nonresident purchaser exemption, keep a copy of the purchaser’s valid out‑of‑state driver’s license in your records as proof of nonresidency. You also are responsible for obtaining a signed certification documenting the purchaser’s eligibility for the nonresident purchaser exemption. As a condition of claiming this exemption, nonresident purchasers must certify that they are not residents of Illinois. See ST‑588, Nonresidency Exemption Certification for Sales and Leases of Motor Vehicles and Trailers, available on our website at tax.illinois.gov. Retain this certification in your records as proof that no tax was due on the sale of the specified item.

Indiana Purchaser of an RV or Cargo Trailer

You must check Section 5, box F, “Other” and enter “recreational vehicle” or “cargo trailer” on the line provided.

B. Sold for resale to a DEALER

Note: When completing Section 6, round to the nearest dollar by dropping amounts of less than 50 cents and increasing amounts of 50 cents or more to the next higher dollar.

ST‑556 (1) Instructions (R‑12/21)

Page 2 of 4

Line 1 Enter the selling price, including accessories, federal excise taxes, freight and labor, dealer preparation, documentary fees, and any rebates or incentives for which you as a dealer receive reimbursement. Do not subtract the value of any rebate made directly to the customer. In general, any cost passed on to the customer as part of the sale of an item and for which gross receipts are received should be included in the selling price. Note: If you are selling a new truck weighing 33,000 pounds

or more or a new trailer or semitrailer chassis weighing 26,000 pounds or more, you may exclude the federal excise tax from the selling price.

Line 2 If you claimed a qualified trade‑in (see Section 4), enter the total trade‑in credit or value (see Note below). You must identify the traded‑in item in the spaces provided in Section 4. If you claimed an exemption in Section 5 and no tax is due, you do not need to complete the remaining Lines 3 – 14 of Section 6. Remember that you and all purchasers must sign the return.

Note: For sales made on or after January 1, 2020, up to and including December 31, 2021, for purposes of calculating your Sales Tax due, you cannot claim trade‑in credit exceeding $10,000 for any first division motor vehicle that was traded in during the sale being reported on Form ST‑556. For sales made on or after January 1, 2022, the $10,000 trade‑in credit limit no longer applies.

Line 3 Subtract Line 2 from Line 1.

Line 4 Calculate your tax due using the following to determine the appropriate rate:

If you made this sale at your standard business location (i.e., the location printed on the front of the paper

Form ST‑556 returns the Department issues to you), multiply Line 3 by the tax rate printed on your return.

If you made this sale at an off‑site location (e.g., a tent sale), follow the instructions on ST‑23, How to Report Off‑Site Sales on Form ST‑556, Sales Tax Transaction Return, or Form ST‑556‑LSE, Transaction Return for Leases, available on our website at tax.illinois.gov.

If you made this sale to a nonresident who is taking delivery of the item in Illinois but who will title it in a state that does not have a reciprocal nonresident purchaser exemption

for Illinois residents, multiply Line 3 by the nonresident’s state sales tax rate, up to 6.25 percent. See ST‑58, Reciprocal ‑ Non‑Reciprocal Vehicle Tax Rate Chart, available on our website at tax.illinois.gov.

Note for business locations in Cook, DuPage, Kane, Lake, McHenry, or Will County when the customer’s address is in Chicago:

If your sales location is in Cook, DuPage, Kane, Lake, McHenry, or Will County and the purchaser’s address on Form ST‑556, Section 1, is within the corporate limits of the city of Chicago, you must collect an additional 1.25 percent (.0125) Chicago Home Rule Use Tax. To help you calculate the tax due on one of these sales, we preprint a combined rate below Line 4 on the paper Form ST‑556 returns the Department issues to you. This combined rate includes your tax rate, plus the additional 1.25 percent Chicago Home Rule Use Tax. To figure the correct tax due, multiply the amount subject to tax on Line 3 by the combined rate. Enter the result on Line 4.

Line 5 - Read these instructions if your buyer’s address is in Cook, DuPage, Kane, Lake, McHenry, Will, Madison, or St. Clair County.

If the item will be titled or registered in an area in which tax has been imposed by the Regional Transportation Authority or Metro‑East Transit District, the purchaser may owe additional tax. If your sales location is within the boundaries of one of these areas, the additional tax is already included in your combined tax rate. If, however, your sales location falls outside these boundaries, you are not required to collect any additional use tax, but you may do your purchaser the courtesy of collecting the additional tax so that the purchaser will not be billed for it later.

If you have determined that the purchaser is subject to the additional use tax and you have decided to collect and remit that additional tax on the purchaser’s behalf, multiply the amount on Line 3 by any difference in rates (expressed as a decimal), and enter the result on Line 5. Finally, enter the name of the Illinois county in which the purchaser’s address is located. If the purchaser’s address falls within the limits of an Illinois city or village, enter the name of the city or village. If the purchaser’s address falls within Madison or St. Clair County, enter the name of the township in which the address is located.

Do not report municipal or county home rule use tax on Line 5. Line 6 Add Lines 4 and 5.

Line 7 If you are filing this return and paying the tax due within 20 days of the date of delivery entered in Section 3, multiply Line 6 by the rate printed on your return.

Note: Line 7a is preprinted only if you have a business location in the Metro-East Mass Transit District portion of St. Clair County.

Line 7a The Illinois Department of Revenue is responsible for collecting and administering the fee imposed in the Metro‑East Mass Transit District on items that are required to be titled or registered in Illinois. Multiply Line 3 by 0.5 percent (0.005).

If the result is less than $20, enter the result on Line 7a.

If the result is $20 or more, enter $20 on Line 7a.

Line 8 Subtract Line 7 from Line 6. If you calculated an amount on Line 7a according to the above instruction, subtract Line 7 from Line 6, and then add to that total the amount on Line 7a.

Line 9 If we have notified you that you have an overpayment credit on your account, you may use this overpayment credit to pay some or all of the tax due on this return. Enter the amount you wish to use.

Line 10 This credit is applicable only to lessors selling previously leased items at the expiration of the lease term. See Form ST‑556 instructions for leasing companies selling at retail (ST‑556[2]) for instructions on how to claim a credit for tax paid on an item you are now selling at the end of a lease.

Line 11 If you collected more tax than is due on this sale, enter the amount you overcollected.

Line 12 Subtract Lines 9 and 10 from Line 8 and add Line 11.

Line 13 If you have a credit memorandum and you wish to use it towards what you owe, enter the amount you are using on Line 13.

Line 14 Subtract Line 13 from Line 12, and enter the amount due. Also, enter the identifying number from the remittance you are sending to pay the tax due on this return. If you are filing more than one Form ST‑556, enclose a separate remittance for each return.

Obtain Answers on St 556 Illinois

  1. Who must file Form ST-556?

    If you are engaged in retail sales in Illinois of items that require titling or registration by a state agency, you must file Form ST-556. This includes vehicles, watercraft, aircraft, trailers, and mobile homes. However, if the item is being sold for lease, you should use Form ST-556-LSE instead. Leasing companies must also file Form ST-556 when selling items at the end of a lease, following specific instructions for leasing companies.

  2. Do I need to file Form ST-556 if no tax is due?

    Yes, you are required to file Form ST-556 even if there is no tax due on the sale. It is essential to report all retail sales of items that must be titled or registered. Failing to file this form can result in penalties for each unreported transaction.

  3. How can I file Form ST-556?

    You can file Form ST-556 electronically through MyTax Illinois at mytax.illinois.gov. If you prefer a paper form, the Illinois Department of Revenue provides preprinted forms in limited quantities. You can request these by calling the Central Registration Division at 217-785-3707 or through MyTax Illinois. Preprinted forms will include information specific to your business locations.

  4. What should I do if I make a mistake on a preprinted paper form?

    If you notice an error on your preprinted Form ST-556, write "VOID" across the form and keep it in your records for at least 42 months. Do not send the voided form back to the Illinois Department of Revenue.

Common mistakes

Filling out the ST-556 Illinois form can be a straightforward process, but many people make common mistakes that can lead to complications. One frequent error is failing to provide the correct purchaser's name and address. The information must match the details on the title or registration application. If there are multiple purchasers, all names should be included. Omitting or incorrectly entering this information can result in delays or penalties.

Another mistake involves misidentifying the item sold. It is crucial to check the appropriate box that corresponds to the type of item. If the item does not fit into the predefined categories, selecting "Other" and providing a description is necessary. Additionally, not entering the identification number, such as a Vehicle Identification Number (VIN), can lead to issues during processing.

Many individuals also neglect to accurately record the date of delivery. This date is significant as the form must be filed within 20 calendar days after the item is delivered. Missing this deadline can result in late fees and penalties, so it is vital to be precise.

Some people mistakenly skip the section on trade-ins. If a trade-in is claimed, it must be described accurately, including the identification number and details of the traded item. Failing to do so can lead to incorrect tax calculations and potential audits.

Another common error occurs when individuals miscalculate the sales tax due. Properly calculating the tax requires understanding the applicable rates, especially if the sale occurs in areas with additional taxes, such as Chicago. Rounding errors can also affect the final amount, so it’s essential to follow the instructions carefully.

Lastly, individuals often forget to sign the return. Both the seller and all purchasers must provide their signatures. Without these, the form may be considered incomplete, leading to processing delays. Ensuring that all required signatures are present is crucial for a smooth filing process.

Documents used along the form

When dealing with the ST-556 Illinois form, several other documents may be necessary to ensure compliance with state regulations. These forms facilitate various aspects of sales tax reporting and exemptions. Below is a list of related forms and documents often used in conjunction with the ST-556.

  • ST-556-LSE: This form is used for reporting transactions related to leases. If you are leasing an item that requires registration, this form is essential instead of the ST-556.
  • ST-556(2): Specifically designed for leasing companies, this form provides instructions for those selling items at retail after a lease has ended.
  • ST-588: This is the Nonresidency Exemption Certification form. It certifies that a purchaser is not a resident of Illinois, allowing for tax exemptions on qualifying sales.
  • CRT-61: The Certificate of Resale is necessary when selling items to dealers for resale. It serves as proof that the purchase is for resale purposes, exempting it from sales tax.
  • RUT-7: This Rolling Stock Certification form is for sales to interstate carriers for hire. It documents that the item will be used for hauling in interstate commerce, qualifying for tax exemptions.
  • ST-23: This document provides guidelines on how to report off-site sales. It is crucial when sales occur outside the standard business location.
  • ST-58: This form outlines the Reciprocal - Non-Reciprocal Vehicle Tax Rate Chart. It helps determine tax rates applicable to nonresident purchasers based on their home state.
  • ST-4: This form is used to claim a sales tax exemption for purchases made by exempt organizations, such as government bodies or charities.

  • Form IL-1040: This is the Illinois Individual Income Tax Return. It may be required for individuals who report income from the sale of items requiring the ST-556 form.

Using these forms alongside the ST-556 ensures accurate reporting and compliance with Illinois tax regulations. Each document plays a crucial role in various sales transactions, helping both sellers and buyers navigate the complexities of sales tax obligations.

Key takeaways

Understanding the ST-556 Illinois form is crucial for anyone involved in selling items that require state registration. Here are some key takeaways to keep in mind:

  • Mandatory Filing: You must file Form ST-556 if you sell items that need to be titled or registered in Illinois, such as vehicles and trailers, even if no tax is due.
  • Electronic Filing: You can easily file Form ST-556 online through MyTax Illinois, making the process more efficient.
  • Voiding Mistakes: If you make a mistake on a preprinted form, write "VOID" across it and keep it for your records. Do not submit the voided form.
  • Accurate Information: Ensure that the purchaser's name and address match those on the title application. If there are multiple purchasers, list them all.
  • Item Description: Clearly describe the item sold and provide its identification number, such as a VIN for vehicles. This is essential for accurate record-keeping.
  • Trade-Ins: If applicable, you can claim a qualified trade-in, but remember that the trade-in credit for certain vehicles is capped at $10,000.
  • Exemptions: If the sale is exempt from tax, check the appropriate box and provide the necessary details to support the exemption.
  • Timely Submission: The return is due within 20 calendar days of the delivery date. Late filings can result in penalties.
  • Signatures Required: Both the seller and the purchaser must sign the return. This step is crucial for validating the transaction.
  • Keep Records: Maintain all documentation related to the sale, including any exemption certifications and voided forms, for at least 42 months.

Filling out the ST-556 form correctly can save you time and potential headaches down the road. Always double-check your entries and stay informed about any updates to the filing process.
