How to Fill Out a G-4 Form for Dummies: Allowances, Exempt, and Filing

To fill out a G-4 form, download the current version from the Georgia Department of Revenue, enter your name, address, and Social Security number, pick the filing status letter that matches your household, count your dependents, add any extra allowances or flat-dollar withholding you want, sign under penalty of perjury, and hand it to your employer. The whole form fits on two pages, and most people never need the second one.

The G-4 tells your Georgia employer how much state income tax to take out of each paycheck. Getting it right keeps you from owing a surprise bill in April or lending the state too much of your money all year. Here is how each part works.

Get the Current Form

Download the G-4 from the Department of Revenue’s “G-4 Employee Withholding” page.1Department of Revenue. G-4 Employee Withholding It is a fillable PDF you can complete on screen or print and fill in by hand. Use the version hosted on the Department’s site, since it reflects the current flat income tax rate of 5.19%.2Department of Revenue. Important Tax Updates

Lines 1 and 2: Your Name, SSN, and Address

Line 1a is your full legal name. Line 1b is your Social Security number. Line 2a is your street address, and Line 2b is your city, state, and ZIP.3Georgia Department of Revenue. Employee’s Withholding Allowance Certificate Form G-4 These fields link your withholding to your account with the Department, so match your tax records exactly.

Line 3: Pick Your Filing Status Letter

Line 3 wants a single letter that stands for your household situation. Each letter carries a different standard deduction, and your employer’s payroll system uses it to calculate the withholding rate.3Georgia Department of Revenue. Employee’s Withholding Allowance Certificate Form G-4

  • A — Single: unmarried, divorced, or legally separated.
  • B — Married filing separate, or married filing joint with both spouses working.
  • C — Married filing joint with only one spouse working.
  • D — Head of household: unmarried and paying more than half the cost of keeping up a home for a qualifying dependent.

Choosing the wrong letter is the most common G-4 mistake. If you and your spouse both work but you pick C, your employer will withhold too little and you may owe at tax time. Dual-income couples should generally choose B.

Line 4: Count Your Dependents

Enter the number of dependents you can claim. Georgia uses the federal Internal Revenue Code definition, with one addition: an unborn child with a detectable human heartbeat qualifies as a dependent under Georgia law.3Georgia Department of Revenue. Employee’s Withholding Allowance Certificate Form G-4 The Department confirmed this after the 2022 Dobbs ruling. No Social Security number is required for the unborn dependent; the only condition is a heartbeat detected at or after six weeks of gestation.4Department of Revenue. Life Act Guidance

Line 5: Extra Allowances (Only If You Use the Worksheet)

Line 5 is optional. Skip it if you take the standard deduction and have no unusual Georgia adjustments, which is true for most filers. If you do have itemized deductions or Georgia-specific adjustments like the retirement income exclusion, flip to the page-two worksheet and work through it in order:

  • Line 1: If you or your spouse are 65 or older or legally blind, check the applicable boxes and multiply the total by $1,300.
  • Line A: Enter your estimated federal itemized deductions.
  • Line B: Subtract the Georgia standard deduction shown on the form.
  • Line C: If the result is zero or less, enter zero.
  • Line D: Add any Georgia-specific income adjustments. The IT-511 tax booklet lists what qualifies.
  • Lines E through G: Add Lines C and D, then subtract any taxable income you receive that is not subject to employer withholding, such as freelance or investment earnings.
  • Line H: Divide the Line G result by $4,000. That number goes on Line 5. If the remainder is more than $1,500, round up.3Georgia Department of Revenue. Employee’s Withholding Allowance Certificate Form G-4

If you write a number on Line 5 without completing the worksheet, the Department of Revenue will automatically deny the claim. Leave it blank if you don’t need it.

Line 6: Ask for Extra Withholding

Line 6 lets you request a flat dollar amount to be withheld from every paycheck on top of the regular calculation.3Georgia Department of Revenue. Employee’s Withholding Allowance Certificate Form G-4 It is entirely voluntary. Use it if you have significant side income or if you know your allowance count will leave you short at filing time.

Line 7: Totals

Line 7 is a summary. Write the letter from Line 3 and the combined total of Lines 4 and 5. This is the figure your employer’s payroll system actually reads.

Sign and Date

Sign and date the bottom of page one. The form includes a certification that you are entitled to the allowances or exemption you’ve claimed, and you sign under penalty of perjury.3Georgia Department of Revenue. Employee’s Withholding Allowance Certificate Form G-4

Claiming Exempt on Line 8

If you expect to owe zero Georgia income tax this year, you can skip Lines 3 through 7 and use Line 8 instead. The general exemption (the first checkbox) requires both of these to be true:

Two things trip people up here. Getting a refund last year does not mean you qualify; a refund just means you overpaid. And you cannot claim exempt if you did not file a Georgia return at all last year.

The second Line 8 checkbox is for military spouses. You qualify if the servicemember is stationed in Georgia under military orders, you are in the state solely to be with them, and both of you keep legal residence in another state under the Servicemembers Civil Relief Act.

An exempt G-4 expires on February 15 of the following year. If you still qualify, submit a new one before that date. If you don’t, your employer must revert to withholding as though you are single with zero allowances.3Georgia Department of Revenue. Employee’s Withholding Allowance Certificate Form G-4

Submit It to Your Employer

Hand the signed G-4 to payroll or human resources. Your employer keeps it on file and uses it to set your state withholding. Georgia law requires employers to withhold state income tax based on the information you provide.5Justia Law. Georgia Code Title 48 – Section 48-7-101

If you never submit a G-4, your employer does not skip withholding. They must withhold as though you are single with zero allowances, the most aggressive setting.3Georgia Department of Revenue. Employee’s Withholding Allowance Certificate Form G-4 The same default applies if your employer knows your form contains errors.

One extra rule: if you claim more than 14 allowances or claim exempt on Line 8, your employer must mail a copy of the form to the Department of Revenue for review. The employer honors the form as submitted unless the Department says otherwise.3Georgia Department of Revenue. Employee’s Withholding Allowance Certificate Form G-4

Keep a copy of every G-4 you submit. If a paycheck looks wrong, your copy tells you whether the error is on the form or in payroll.

When to File a New G-4

Your G-4 stays on file indefinitely until you replace it, except for exempt claims, which expire each February 15. File a new one whenever something changes that would affect your withholding:

  • Marriage or divorce, which changes your filing status letter.
  • A new child or dependent, which raises your Line 4 count.
  • A spouse starting or stopping work, which may shift you between status B and status C.
  • A meaningful change in non-wage income, such as investment gains, freelance work, or rental income, which may call for extra withholding on Line 6.
  • Expecting to owe tax next year after owing nothing this year. In that case, you must give your employer a new G-4 by December 1.

A good habit is to review your G-4 each year when you file your Georgia return. If you owed more than a few hundred dollars or received a very large refund, adjusting now prevents a repeat.

The G-4 Is Not the Federal W-4

The federal W-4 was redesigned in 2020 and no longer uses numbered allowances. Georgia’s G-4 still does. Your W-4 choices do not carry over to your state withholding, so you have to submit both forms separately, and getting one right does not guarantee the other is right.

Penalties for False Information

The G-4 is signed under penalty of perjury. Under O.C.G.A. § 48-7-127, willfully providing false or fraudulent information on a withholding certificate, or intentionally failing to supply information that would increase the tax withheld, is a misdemeanor.6Justia Law. Georgia Code Title 48 – Section 48-7-127 A misdemeanor conviction in Georgia can carry a fine of up to $1,000, up to 12 months in jail, or both.7Justia Law. Georgia Code Title 17 – Section 17-10-3

Honest mistakes are not the target. The statute requires the false information to be willful. But claiming exempt when you clearly expect to owe, or inflating allowances to zero out your withholding, could cross that line.

If Your Withholding Turns Out Wrong Mid-Year

Submit a corrected G-4 as soon as you notice. If too much has already been withheld, you cannot recover it through your employer mid-year; you claim the overpayment as a refund on your Georgia return. If too little has been withheld, a corrected G-4 stops the shortfall going forward, but you will still owe the difference at filing. Adding a flat dollar amount on Line 6 for the rest of the year can help you catch up and avoid an underpayment penalty.
