Common confusion points
Should I use the online estimator or complete Step 2(b)?
The choice depends on whether the filer has other income sources besides the job associated with Form W-4 (sp). Use the estimator if they have side work or want greater accuracy.
→ Check which situation applies to determine if using the estimator at www.irs.gov/W4AppSP is best.
How do I handle having two jobs?
The filer can use a specific box on Page 1, or complete Step 2(b) for both jobs and enter the results in Step 4(c).
→ Check if one job's pay is more than half of the other job's pay to decide between using the box method or Step 2(b).
What does 'other income sources' mean for Steps 2(c) and 4(a)?
It refers to income received from sources besides the work covered by this Form W-4 (sp), such as self-employment.

→ Check Page 1 (Step 2(c)) versus Page 4 (Step 4(a)) to see which information is required.
When should I use the estimator at www.irs.gov/W4AppSP?
The filer should consider using it if they are filing after the start of the year, expect to work part of the year, or have self-employment income and want to pay those taxes via withholding.
→ Verify these three conditions on Page 2.
What is the purpose of Step 1(c)?
It requires marking the filer's expected marital status for filing purposes, which determines the standard deduction and tax rates used in calculating withholding.
