RV and Cargo Trailer Sales - Nonresident Sales Tax Exemption

Beginning with the July 2017 tax period, recreational vehicle and cargo trailer dealers should no longer use the current ST-103 return. A different Indiana sales tax return, ST-103CAR, should now be used by recreational vehicle and cargo trailer retailers. You should begin using this return, either through INtax or another approved filing method, beginning with the July 2017 tax period. To update your return template to the ST-103CAR form, contact us via the INtax message center, mail, or fax to (317) 232-1021. Instructions for this return are available on the department website.
