What New York Form ST-125 (2011) Is For
New York Form ST-125 (2011) is a sales and use tax exemption certificate that allows farmers and commercial horse boarding operators to purchase certain property and services without paying New York State and local sales taxes. This certificate serves as official documentation presented to sellers proving that specific purchases qualify for tax exemption under New York tax law. The form enables eligible agricultural businesses to reduce their operating costs by eliminating sales tax on qualifying items used predominantly in farm production or commercial horse boarding operations.
The certificate can be used either as a single-purchase document for one transaction or as a blanket certificate covering multiple purchases of the same general type of property or service from the same seller. To qualify for exemption, the property or service must be used more than 50% of the time in eligible farm production activities or commercial horse boarding operations. The form covers a wide range of exempt purchases including farm machinery, equipment, building materials, installation and repair services, utilities, and veterinary drugs for livestock and poultry, though it cannot be used for motor fuel (gasoline) or highway diesel motor fuel purchases.
When You’d Use New York Form ST-125 (2011)
Timing Requirements
You must provide Form ST-125 (2011) to the seller within 90 days after the delivery of property or performance of service to claim the exemption. The New York Department of Taxation and Finance allows this 90-day window to ensure proper documentation exists for tax-exempt transactions. If you fail to provide the certificate within this timeframe, both you and the seller could face liability for the uncollected sales tax.
Corrections and Refund Situations
While the form itself is not "amended" in the traditional sense of correcting previous filings, you may need to issue a new or corrected certificate if information changes or if the original certificate contained errors.
If you paid sales tax on a purchase that should have been exempt, you cannot retroactively use Form ST-125 (2011). Instead:
- File Form AU-11, Application for Credit or Refund of Sales and Use Tax
- Use Form FT-500 for motor fuel refunds

FAQs
Can I use Form ST-125 (2011) if I only farm part-time or have a small hobby farm?
Yes, as long as you produce goods for sale. There is no minimum size or revenue requirement. The key is that your activity qualifies as farm production and the purchased items are used predominantly (more than 50%) in that production. Hobby activities without sales do not qualify.
What is the difference between requirements for farmers and commercial horse boarding operators?
Farmers have no minimum size or revenue requirements and do not need a Certificate of Authority. Horse boarding operations must meet acreage, horse count, and revenue thresholds, and must register with the Tax Department.
Can I use this certificate to buy a pickup truck or tractor without paying sales tax?
Yes, if the vehicle is used more than 50% in qualifying activities. Keep usage records to support the exemption.
Why can't I use Form ST-125 (2011) to buy gasoline or diesel fuel?
State law prohibits it. You must pay tax upfront and request refunds using the appropriate forms.
What happens if I provide the exemption certificate after 90 days?
Both you and the seller may be liable for the tax. Late certificates remove seller protection, so always submit promptly.
Can contractors and repairmen use Form ST-125 (2011) for farm projects?
Yes, but Form ST-120.1 is usually more appropriate. Materials must become part of qualifying structures.
If I make a mistake on the certificate, how do I correct it?
Provide a corrected certificate to the seller immediately. Replace the incorrect version and resolve any tax issues if necessary.
