TL;DR
- ✅ To get more back: enter extra withholding in Step 4(c) (extra refund ÷ paychecks left)
- ✅ To owe less: claim every credit and deduction at filing
- ✅ Allowances no longer exist; “claim 0” is now Step 4(c)
- ✅ A refund is your own money back, with no interest
Way 1: withhold more during the year
Add a flat dollar amount to Step 4(c) of your W-4. Your employer takes it out of every paycheck on top of the normal withholding, and the total comes back as a larger refund. The formula is the extra refund you want divided by the paychecks you have left.
$1,000 more, paid biweekly, 26 paychecks left
$1,000 ÷ 26 = about $39 per paycheck in Step 4(c).
$1,200 more, paid monthly, 12 paychecks left
$1,200 ÷ 12 = $100 per paycheck in Step 4(c).
$1,200 more, but only 3 monthly paychecks left
$1,200 ÷ 3 = $400 per paycheck. Starting late costs more per paycheck.
The full explanation, with more examples, is in the Step 4(c) guide. Leaving Steps 2 to 4 blank, or checking the Step 2 box when you have two jobs, also pushes withholding up.

Open the W-4 Calculator →Way 2: owe less on your return
This is the way that creates a real refund rather than returning your own money. It happens at filing time, not on the W-4.
- Claim every credit you qualify for: child tax credit ($2,200 per child under 17), the credit for other dependents ($500), the earned income credit, education credits.
- Use the new 2026 deductions if they apply: tips, overtime, seniors, car loan interest. See how the 2025 tax law changes your W-4 and tips and overtime.
- Compare the standard deduction with itemizing, especially with a mortgage, large medical costs or state tax.
- Contribute to a retirement account or HSA before the deadline if it reduces taxable income.
⚠️ A big refund is not free
The average refund is thousands of dollars that you could have had in each paycheck all year. Before you add extra withholding, read refund vs. adjusting your W-4, and if you ever owe, use how much to withhold to check where you stand.
What does not work
- Writing a false filing status or dependents on the W-4 to inflate your refund. The IRS can penalize incorrect withholding certificates.
- Claiming exempt. That stops all withholding and usually creates a bill. See W-4 exempt.
- Looking for “allowances to claim”. There are none; see what replaced allowances.
Frequently asked questions
How can I get a bigger refund?
Two ways. During the year, ask your employer to withhold more by entering a flat amount in Step 4(c) of your W-4. At filing, claim every credit and deduction you qualify for. The first only returns your own money; the second can actually lower your tax.
How much should I put in Step 4(c) for a refund?
Take the extra refund you want and divide it by the paychecks left in the year. For a $1,200 larger refund with 24 paychecks left, enter $50.
Can I still claim 0 on my W-4 to get a bigger refund?
No. Allowances were removed in 2020. The equivalent today is extra withholding in Step 4(c), and leaving Steps 2 to 4 otherwise blank.
Is a bigger refund good?
A refund is your own money returned without interest. It is a forced savings habit for some people and a lost opportunity for others. Whether it is better than keeping more in each paycheck depends on your discipline and whether you carry high-interest debt.
What if I get less back than expected?
Common reasons are a second income, side income with no tax withheld, a lost credit such as a child who aged out, or a W-4 that did not change after a life event. Compare year-to-date withholding with your return to find the gap.
