Common confusion points
Should I use Step 2 if I have more than one job?
This step determines how additional tax is calculated when there are multiple jobs.
→ Check Step 2; submit a separate Form W-4 for each job.
What is the threshold for entering deductions on Line 6a (State and local taxes)?
The limit depends on filing status: $505,000 total income generally allows up to $40,400 paid (or $20,200 if married filing separately).
→ Check your total income against the limits provided in Step 4(b).
When claiming exemption from withholding, do I still need to fill out all steps?
No; if exempt, the filer checks the box and completes only Steps 1(a), 1(b), and Step 5.
→ Verify that no other steps are completed on Form W-4.
What is the income limit for entering qualified tips (Line 4a)?
The limit is $25,000, unless married filing jointly, in which case it is $300,000 total income.
→ Check your total income against the limits listed next to Line 4a.
If I am married filing separately and have two jobs, how do I handle Step 2?
You must use Step 2; you cannot simply check Option (c) box without following the instructions for multiple jobs.
→ Ensure a separate Form W-4 is submitted for each job if using Step 2.
What should I enter on Line 5 (Other adjustments)?
Enter an estimate of student loan interest, deductible IRA contributions, educator expenses, alimony paid, and certain other adjustments from Schedule 1 (Form 1040), Part II.
