Add the payroll register, the wage reconciliation, the benefits statement, the state allocation and the employee’s records. Fyllyo fills the W-2’s copies on your Mac and shows the lines behind each answer for you to check.
A W-2 is a page of boxes, but the amounts come from a payroll register, a year-end reconciliation and a benefits statement that each show several wage totals, codes and addresses. Software has to put each number in its own box. These are the common places AI tools and autofill get it wrong. What the form requires is for the IRS to say. Follow its instructions. IRS instructions for Form W-2.
Boxes 1, 3 and 5 often hold different amounts, because some pre-tax deductions come out of one and not the others. Payroll records also show gross pay. Software can copy gross pay into every wage box, or one total into all three.
Payroll registers are printed on the provider’s letterhead, with the employer named as a client. Software can take the provider’s name and address as the employer’s.
An employee who moved during the year still has the old address on early records, and the payroll provider may not have caught up. Software can copy the first address it sees.
After a move, wages are split between two states, each with its own employer ID. Software can report all wages to the home state, use last year’s allocation, or mix one state’s ID with the other’s amounts.
Statutory employee is a narrow category the form’s instructions define. Software can mark it because the job title says sales, or mark every box 13 checkbox that has a benefit behind it.
