- Claiming the credit without a DRS voucher. The credit may be claimed only if DRS has issued a tax credit voucher.
- Exceeding the employee limits. Part II says not to enter more than $5,250 in principal payments for any employee. The credit cannot exceed $2,625 per qualified employee for an income year.
- Leaving out required attachments. Include the voucher copy, proof of payment to the servicer and detailed employee qualification schedule.
Questions people ask
How much is the credit?
The credit equals 50% of qualified payments the employer makes toward outstanding student loan principal during the income year. It is limited to $2,625 per qualified employee for that income year.
Can a small business receive the credit as a refund?
Certain small businesses can elect to receive the credit as a refund. The form defines a small business as a qualified employer with gross receipts of $5 million or less in the applicable calendar or income year.
What if an employee worked and lived in Connecticut for only part of the year?
The employer may claim the credit for a payment made during the part of the income year when the qualified employee worked and resided in Connecticut. An employee who worked and resided in the state for any part of a month is treated as having done so for the entire month.
