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

To fill out a G-4 form, enter your name, Social Security number, and Georgia address at the top; choose a filing status letter A through D from Line 3; count your dependents on Line 4; complete the Line 5 worksheet if Georgia-specific adjustments apply; write your chosen letter and the sum of Lines 4 and 5 on Line 7; add any extra dollar amount you want withheld on Line 6; then sign and date. Give the completed form to your employer’s payroll department before your first paycheck.¹

Before You Start

The G-4 is Georgia’s version of the federal W-4. It tells your employer how much state income tax to withhold from each paycheck. Georgia law requires you to submit one to every new employer before your first check goes out, and you should file a new one any time your circumstances shift, such as marriage, divorce, a new child, a second job, or a spouse leaving the workforce.² There’s no cap on how many times you can update it during the year.

Skipping the form doesn’t save you anything. If you never turn one in, your employer must withhold at the highest rate, treating you as single with zero allowances, which pulls more from your paycheck than most people actually owe.²

Have this ready before you sit down with the form:

Your Social Security number and current Georgia address.
Your marital status and whether your spouse also earns wages.
A list of your dependents under federal tax rules.
Records of any Georgia-specific deductions or adjustments (retirement income exclusion, interest from U.S. government obligations, itemized deduction estimates) if you plan to use Line 5.
Last year’s Georgia return if you’re considering exempt status.

Line-by-Line Walkthrough

Here is what belongs in each field on the form itself.³

Lines 1a and 1b: Name and Social Security Number

Your full legal name and SSN. Match what’s on your Social Security card.

Lines 2a and 2b: Address

Home address, city, state, and zip. This establishes Georgia residency for withholding purposes.

Line 3: Filing Status Options

Line 3 shows the four filing status choices (A, B, C, and D). Read them and decide which letter fits. You don’t write anything on Line 3 itself; your choice goes on Line 7.

Line 4: Dependent Allowances

Enter the number of people who qualify as your dependents under federal tax rules. That generally covers children under 19 (under 24 if full-time students) and other relatives you financially support who pass the IRS dependency tests. Georgia also recognizes an unborn child with a detectable heartbeat as a qualifying dependent under O.C.G.A. § 1-2-1, so you can add an allowance during pregnancy. Be ready to support the claim if the Department of Revenue asks.

Line 5: Georgia Adjustments Allowances

Line 5 captures allowances tied to Georgia-specific deductions and adjustments. You cannot estimate this number. The form’s second page has a required worksheet that walks you through your federal itemized deductions (if you itemize), the Georgia personal exemption for your filing status, and any Georgia-specific adjustments, then divides the total by $4,000 to produce the allowance figure. Skip the worksheet but enter a number here, and the claim will be denied automatically.³

Most people with straightforward W-2 income end up with zero on Line 5, and that’s fine. Leave it blank or write 0.

Line 6: Additional Withholding

An optional flat dollar amount you want taken from every paycheck on top of the calculated withholding. Use it if you have side income, investment gains, or other earnings that aren’t subject to payroll withholding, or if you’ve owed money at tax time in the past and want a simple fix.

Line 7: Your Letter and Your Total

Two entries. First, write the filing status letter (A, B, C, or D) you picked from Line 3. Second, write the sum of Lines 4 and 5. Your employer uses both to look up the correct withholding in the state’s tax tables.

Line 8: Exempt Status

Only for people claiming complete exemption from Georgia withholding. If you fill in Line 8, skip Lines 4 through 7 entirely. Details on who qualifies are below.

Signature and Date

Sign and date at the bottom. The signature line carries a penalty-of-perjury statement, so you’re certifying that every entry is truthful. Filing false information on a G-4 is a misdemeanor under Georgia law.⁴

Picking the Right Filing Status Letter

The G-4 uses four letters where a federal return uses five statuses, and the groupings don’t line up with what you’re used to. This is the choice that most often gets people in trouble, so read carefully.³

A — Single. You’re unmarried, or you’re married filing a separate return and your spouse doesn’t work.
B — Married Filing Separately, or Married Filing Jointly With Both Spouses Working. One letter covers two situations because the withholding math is the same. If both spouses earn wages, you use B whether you plan to file jointly or separately.
C — Married Filing Jointly, One Spouse Working. Only one spouse earns wages. Withholding is lightest here because the full joint exemption applies to a single income.
D — Head of Household. You’re unmarried (or considered unmarried) and pay more than half the cost of keeping up a home for a qualifying dependent.

The most expensive mistake is a two-income married couple picking C. Letter C assumes one paycheck supports the household, so it withholds too little. If both spouses work and both check C, you’ll almost certainly owe at tax time.

How Allowances Work

Each allowance reduces the wages your employer treats as taxable for withholding purposes. More allowances mean less tax withheld per check. Line 4 handles dependents; Line 5 handles Georgia-specific adjustments through the worksheet. Add them together for the total you report on Line 7.

If both spouses work, don’t double-count dependents. Claim them on one spouse’s G-4 and zero on the other’s. This keeps the arithmetic honest and avoids a shortfall at filing.

When You Can Claim Exempt on Line 8

Line 8 tells your employer to withhold no Georgia income tax at all. You qualify only if both of these are true:

You filed a Georgia return last year and your tax liability was $0 (Line 4 of Form 500EZ or Line 16 of Form 500).
You expect to file a Georgia return this year and again owe nothing.

Getting a refund last year does not mean your liability was zero. A refund only means you overpaid. And if you didn’t file a Georgia return at all last year, you cannot claim exempt, even if you had no income.³

Exempt status expires on February 15 of the following year. To keep it, submit a fresh G-4 before that date. Miss the deadline and your employer reverts to withholding as single with zero allowances.⁵

Military Spouse Box

The second box under Line 8 is for spouses of active-duty servicemembers claiming exemption under the federal Military Spouses Residency Relief Act. All four conditions must be true:

The servicemember is stationed in Georgia under military orders.
You are in Georgia solely to be with the servicemember.
The servicemember’s legal domicile is in another state.
Your domicile matches the servicemember’s, or you’ve elected to use the same residence for tax purposes.

Check the box, return the form to your employer, and be prepared to provide the servicemember’s orders and a DD Form 2058 showing their permanent state of residency if the Department of Revenue asks.⁶

Common Mistakes That Cost Money

A few patterns show up over and over:

Two-income couples choosing C instead of B, then owing at tax time.
Writing the filing status letter on Line 3 instead of Line 7.
Entering an allowance number on Line 5 without completing the required worksheet, which voids the claim.
Claiming exempt because last year produced a refund, without checking whether the actual tax liability was $0.
Forgetting to file a new G-4 by February 15 to renew exempt status.
Ignoring side income; Georgia doesn’t automatically withhold on freelance work, rental income, or investment gains. Either add a flat amount on Line 6 or make quarterly estimated payments on Form 500-ES.

Submitting the Form and Checking Your Pay Stub

Give the completed G-4 to your employer’s payroll or HR department. Most companies accept it through an internal portal with a digital signature; some still want paper. You do not mail the form to the Georgia Department of Revenue yourself.¹

One exception: if you claim more than 14 allowances or claim exempt status, your employer must mail a copy of the form to the Department of Revenue for review. If the department finds the form erroneous, the employer will be told to disregard it and withhold at the single-zero rate until you submit a corrected version.³

Updated withholding usually appears within one or two pay cycles. Check your pay stub after that window to confirm the filing status letter and allowance count match what you turned in. If anything looks off, submit a corrected G-4 immediately rather than waiting for tax season. And review the form once a year, ideally in January, when exempt claims expire and Georgia’s withholding tables may have shifted.
