Who is required to file
Airline Companies that have regularly scheduled flights into the state of South Carolina are required to file for airline property tax.
Filing a Late Return
If a return is filed after the due date of April 30, then a 10% penalty will be added to the tax amount due.
An amended return may be filed within three years from the date the original return was filed or due to be filed, whichever is later. A letter of explanation and any supporting documentation should be attached to the amended return for review.
Bills and Payments
There is no payment due at the time of filing a PT-418. A bill will be mailed to the taxpayer at the end of September or beginning of October. The payment is due by December 31.
