The payroll withholding and unemployment tax system is in-house SQL server based software that tracks the payments of payroll withholding and unemployment tax liabilities for your federal, state, and local jurisdictions. LT Tax is designed to receive data from any source payroll system. Payments are made via EFTPS, NACHA, and feeds to your accounts payable or other financial systems. Signature-ready federal schedule 941, 941-X, 940, 944, 945 and 1042, state and local withholding recaps and SUTA forms are all generated from the system. LT Tax is a compliance tool under your control!
