Fill out Form ST-120 Online in 2026

Form ST-120, also known as the Resale Certificate, is important for businesses purchasing items they intend to resell. This form allows buyers to avoid paying sales tax upfront on those items. By completing and providing this certificate to the seller, the buyer certifies that they will resell the goods rather than use them. It helps maintain accurate tax records and ensures that sales tax is collected only when the item is sold to the final consumer. Proper use of this form is essential for compliance with tax laws.

Form ST-120 is used in New York to buy goods without paying sales tax. It is important for businesses:

• to claim tax exemption on purchases.
• to provide proof of resale to suppliers.
• to ensure compliance with tax regulations.

Form ST-120 is completed by registered New York State sales tax vendors, out-of-state vendors, purchasers buying tangible personal property or services for resale, wholesalers, online sellers from New York, and temporary vendors at trade shows.

After completing the form, it is used by sellers to validate tax exemptions for sales to eligible purchasers.

When purchasing items for personal use rather than for resale, Form ST-120 is not needed. Additionally, if you claim exemptions that aren't related to resale, different forms should be used.

If sales tax is collected at the time of purchase or if you aren't engaged in reselling the items or services bought, you do not need to provide this resale certificate.

The deadline for Form ST-120 is flexible. It should be submitted within 90 days of the purchase, preferably at the time of the sale.

If you are using a blanket certificate for multiple purchases from the same seller, submit it before or at the time of purchase. Always keep records of your transactions to avoid any issues.
