Kentucky Form 740NP-WH-EXT is the official document used to request a six-month extension of time to file the “Kentucky Nonresident Income Tax Withholding on Distributive Share Income Report” (Form 740NP-WH). Under Kentucky statutes (KRS 131.081, 131.170, 141.170), pass-through entities such as partnerships and S-corporations can gain extra time to prepare their withholding returns without facing failure-to-file penalties, provided they file this request properly. Importantly, this extension applies only to the filing of the return, not the payment of any tax due; estimated tax liabilities must still be paid by the original deadline to avoid interest and late payment penalties. Submitting this form effectively bridges the gap between the standard due date and the extended deadline, ensuring your business stays compliant with state regulations while gathering necessary financial data.
Ways To Obtain An Extension
You do not necessarily have to file this specific paper form to get an extension. The Department of Revenue accepts three valid methods:
- File Form 740NP-WH-EXT: Submit this specific extension voucher before the original due date of the return.
- Use Other State Extensions: If you file a Kentucky Corporation/LLET Extension (Form 720 EXT) or an Extension for Individual/General Partnership returns (Form 40A102), simply attach a copy of that approved extension to your Form 740NP-WH when you eventually file it.
- Use Federal Extension: If you have filed for a federal extension using Form 7004, you can attach a copy of that federal form to your Kentucky return when you file by the extended deadline.
Electronic Payment Requirement
For tax years beginning on or after October 1, 2021, most corporations and pass-through entities are legally required to file and pay electronically.
