Greg has one employer, and his only source of income is wages. In 2019, he claimed the standard deduction and no other deductions or credits. He received a large refund after filing his 2019 tax return. In 2020, Greg expects no changes to his tax situation. He would like to pay less in taxes throughout the year, even if that means a lower refund when he files his 2020 return. Which of the following is most likely to help Greg achieve this goal?

A. Complete only Steps 1 and 5 of the 2020 Form W-4, entering personal information and filing status and signing the form. Tax will be computed only on the standard deduction amount and tax rates for Greg's filing status.

B. Select the "married, but withhold at higher single rate" option.

C.Complete Step 2 and use the IRS tax estimator to determine the amount to enter.

d. Enter a negative amount of withholding in Step 4(c).
