Georgia Counts Part-Days: How the 183-Day Test Reads Your Calendar

Most people picture a 183-day test as whole days: nights slept, weeks spent, months ticked off. Georgia's statute does not count that way. Its residency definition adds up "days or part-days". The Georgia part of a day trip, a layover or an afternoon meeting in Atlanta goes into the same total as a full week at home.

That one phrase changes how a year of travel adds up, and a mental tally gets it wrong more easily than any other part of Georgia's rules. This post is about the count itself: what goes into it, when it is read, and where it stops deciding anything.

What Georgia's statute says

Georgia defines a resident in O.C.G.A. §48-7-1(10), and the test is applied on "income tax day", which is December 31 for calendar-year taxpayers. On that day, a person is a Georgia resident if any one of three things is true:

1. They are a legal resident (domiciliary) of Georgia.
2. They live in Georgia "on a more or less regular or permanent basis and not on the temporary or transitory basis of a visitor or sojourner".
3. They have been residing in Georgia for "183 days or part-days or longer, in the aggregate, out of the immediately preceding 365-day period".

The third test is the day count, and it is the subject of this post. The other two are not counts at all, and they come back below. Our Georgia tax residency guide sets out the full definition, together with the 4.99% flat rate for 2026, Form 500 and Schedule 3, and the retirement income exclusion.

Three phrases that do most of the work

"Part-days." The statute counts a partial day the same as a full one. An afternoon in Georgia is a Georgia day. The definition has no fraction to work out and no minimum number of hours.

"In the aggregate." Days do not need to be consecutive. Scattered days across the period add together, so twenty separate short visits count exactly as much as one twenty-day stay.

"Preceding 365-day period." The count covers the 365 days ending on income tax day, not whatever period feels natural to the person counting.

What the definition leaves out matters as much. It has no statutory exception for travel days or medical days, so there is no category of days to subtract from the total.

How common days count

Day in the record	Counts toward Georgia's 183?
A full day spent in Georgia	Yes
An afternoon in Georgia, with the rest of the day elsewhere	Yes, as a part-day
A connection through Hartsfield with a night downtown	Yes
A day in Georgia for travel or medical reasons	No exception appears in the definition
Twenty separate visits across the period	Yes, all twenty, added together

The table covers only how the day count treats a day. Whether a given total makes someone a resident also depends on the two tests that are not counts.

Why part-days break mental arithmetic

For the same year, a count of whole days and a count that includes part-days can come out far apart. The gap is widest in the situations the guide says catch people out:

• Commuters into Atlanta from a neighbouring state. A workday that starts and ends at home across the state line still includes hours in Georgia. Each of those workdays is a Georgia part-day.
• People splitting the year between Georgia and Florida, Tennessee or the Carolinas. Leaving the Georgia home and arriving back at it each make a Georgia part-day, whatever else happens that day. A year described as "mostly in Florida" is not what the statute measures. It measures the total of days and part-days.
• Remote workers and travelling employees. Scattered Georgia work days rarely feel like a residency question, because no single trip is long. The statute adds them up anyway.
• Frequent flyers through Atlanta. A connection with a night downtown is one of the guide's own examples of a day that counts.

In each case, the intuitive estimate comes from where someone felt they were based. The statute's figure comes from every day Georgia appears in the calendar at all. For how years split between two homes get documented, see our snowbird's guide to managing dual-state residency.

When the count is read

All three tests in Georgia's definition are applied on December 31 for calendar-year filers. That has two consequences for anyone keeping a running count.

First, the number that matters is the total on that date, over the 365 days before it. A count taken in June is a forecast of that figure, not the figure itself.

Second, the day count is not the only way to become a resident on that date. The "regular or permanent basis" test can apply before 183 days are reached. The guide's examples of presence that looks settled rather than temporary by December 31 are a family that has relocated, a job with no end date, and a year-round home. A total below 183 answers the day-count test and nothing else.

Where the count stops deciding

Two parts of Georgia's rules are not day counts, and a day log cannot settle either of them alone.

Domicile. The first test asks about legal residence: where someone's true, fixed home is. That home stays their domicile until they establish a new one somewhere else. The factors the guide lists describe the shape of a life rather than a tally:

• where the home and household are
• driver's licence, voter registration and vehicle registration
• the address on the federal return
• where the job or business operates
• where the person's time actually went

Days are one input among several.

The continuation rule. Once someone is a Georgia resident, the statute treats them as remaining one until they show the revenue commissioner that they have become a legal resident or domiciliary of another state. Moving day does not end residency automatically. The person who left carries the burden of proof, and the guide says this rule does most of the work in disputes over whether someone really left.

Whether a move has been proven depends on domicile and evidence, not on a day count. What a day count can show is where the time went, which is one of the things Georgia looks at. For how residency audits generally run, see what to expect from a tax residency audit.

A separate number for nonresidents

Nonresidents face a different threshold, and it is not measured in days. Georgia's de minimis exception for nonresident employees depends on pay. If Georgia work pay is not more than the lesser of 5% of total income or $5,000, no return is required. Above that, wages for work done in Georgia require Form 500 with Schedule 3.

Days matter again on Schedule 3. It splits income between Georgia and everywhere else, and the guide says the split of work days between Georgia and other places is among the numbers most often challenged for part-year and nonresident filers. A nonresident can be nowhere near 183 Georgia days and still need an accurate count of Georgia work days.

What a record has to show

The day-count test is pure arithmetic, so the guide's point is that records made at the time decide it. A reconstruction put together in December has to recover every afternoon, every layover night and every commuting day, and short part-days are the easiest to forget. The guide pairs an automatic day log with flight, card and toll records as the evidence a count like this needs.

iReside records which country and state its user was in on each calendar day, using the iPhone's location in the background. It keeps a running day count for each rule the user tracks, so the figure exists throughout the year instead of being rebuilt in December. The day-by-day record exports as CSV or PDF, and each day is labelled with where it came from: GPS, manual entry, or a planned future day. In an export, a day entered by hand can be told apart from a day recorded from location. Flight, card and toll records remain the supporting evidence for days spent partly in more than one place. For a general method, see how to track tax residency days.

The short version

• Georgia's day-count test is 183 days or part-days, added together, over the 365 days ending December 31.
• An afternoon counts. Days do not need to be consecutive. The definition has no travel or medical exception.
• A total under 183 does not answer the domicile test or the "regular or permanent basis" test.
• Leaving does not end residency automatically. Under the continuation rule, the person who left has to prove it.
• Whether a nonresident has to file depends on pay, not days. The Schedule 3 split of work days is still one of the most often challenged numbers.
