large credit?

You might request a variation if, for example, the regular rate of withholding would lead to a large credit at the end of the income year because your tax deductible expenses are higher than normal.



I'd like to know what 'large credit' means?
Please help me.

A large credit -- money the gov't owes YOU. A big tax refund, in other words.

In financial terms, credit = money that comes INTO your account, or is available for you to spend; debit = money that is being withdrawn from your account, that you pay to someone else.
