Voluntary Contribution Additional monies paid into an employer experience rated SUI account, other than quarterly payments. A voluntary contribution can allow the employer to obtain a more favorable tax rate. In most states the contribution will increase the reserve balance of the account while other states credit the contribution to erase previous charges. Nearly half of the states allow employers to make a voluntary contribution payment to their experience rated account. From year to year, additional states may also allow a voluntary contribution.

Voluntary Contribution Analysis This analysis determines if a voluntary contribution is profitable for the employer. ADP-UCS prepares a report for our clients detailing the contribution amount required to reduce the SUI tax rate. If the contribution amount exceeds the net savings, our recommendation will be to not make the contribution. If the net saving exceeds the contribution amount, detailed instruction will be supplied on how to make the contribution payment to the state agency. Many states will print on the tax rate notice the amount an employer can pay as a voluntary contribution. Most states will not outline if the payment represents net savings or a net loss to the employer. A substantial change in taxable payroll can affect the contribution analysis, if your business expects a change of this nature, please notify your UCS Client Service Representative.
