The Cumberland and Galleria corridor is full of companies that are local in address and national in reach: distributors shipping from warehouses in three states, IT and staffing firms with employees working remotely across the Southeast, regional headquarters for groups with operating subsidiaries elsewhere, and professional firms billing clients from Florida to Texas.
For these businesses, the federal return is rarely the hard part. The hard part is everything that happens when a Georgia company earns income, hires people or sells into other states. Each state has its own rules for when it can tax you, how much of your income it can claim, and what it expects you to file. This guide covers the corporate and multi-state tax questions Cumberland companies run into most often.
Where the federal and Georgia calculations start
A C corporation generally pays federal income tax at a flat 21% rate. Georgia adds its own corporate income tax, and the state has tied the corporate rate to its flat individual rate, which drops to 4.99% for tax years beginning on or after January 1, 2026. Georgia also imposes a separate, graduated net worth tax on corporations. Corporations with net worth of $100,000 or less are exempt, and for most others the amount is small, but it still requires attention on every return.
The Georgia return does not simply copy the federal one. Georgia has not adopted federal bonus depreciation, so a company that expensed equipment federally will usually depreciate the same assets more slowly on the Georgia return. Georgia adopts the Internal Revenue Code as of a fixed date, currently federal law enacted on or before January 1, 2026, with specific exceptions, so later federal changes do not automatically flow through. Keeping a separate Georgia depreciation schedule is not optional for companies with meaningful capital spending.
Nexus: when another state can tax you
Nexus is the connection that allows a state to impose its tax on your business. Physical presence still creates it: an office, a warehouse, inventory, or employees working in the state, including remote employees working from home. A single employee in Tennessee or North Carolina can be enough.
Physical presence is no longer required, however. Since the Supreme Court’s 2018 decision in South Dakota v. Wayfair, states can require sales tax collection based on substantial economic or virtual contacts without physical presence, and many states apply similar economic presence standards to income or franchise taxes. A Cumberland company that has never set foot in a state can still owe tax there once its sales cross that state’s threshold.
One federal law limits this. Public Law 86-272 prevents a state from imposing a net income tax on a business whose only activity in the state is soliciting orders for tangible personal property, where orders are approved and shipped from outside the state. Its protection is narrower than many owners assume:
- It does not apply to services, software as a service, or other intangibles.
- It does not apply to gross receipts taxes or franchise taxes measured by something other than net income.
- Activities beyond solicitation, such as installation, repairs or some types of customer-facing online interaction, can remove the protection.
Apportionment: how much of your income each state gets
Once a company has nexus in more than one state, each state uses a formula to decide what share of total income it can tax. Georgia apportions most corporate income using a single factor based on gross receipts, so the share of your sales sourced to Georgia drives the share of your income Georgia taxes.
The complication is that states do not agree on how to source sales. For services and intangibles, many states now use market-based sourcing, assigning the receipt to where the customer receives the benefit, while others still look to where the work is performed. Differences in formulas and sourcing rules between states can leave part of a company’s income taxed twice, or not at all. Neither outcome is safe to ignore: double taxation is a cost, and untaxed income is often a sign of an unfiled return somewhere.
Sales tax is a separate question
Income tax nexus and sales tax nexus follow different rules. Georgia requires remote sellers to collect sales tax once they have more than $100,000 in gross revenue from, or 200 or more separate retail sales into, Georgia in the current or previous calendar year, and every other state with a sales tax has its own threshold. Marketplace facilitators collect on sales made through their platforms, but that does not cover sales through your own website or sales reps.
What is taxable also varies. Software as a service, digital products and many services are taxed in some states and exempt in others. Uncollected sales tax does not disappear. It becomes a liability of the business, usually discovered during an acquisition, a financing or a state audit, with interest and penalties attached. Our sales and use tax team handles registration and filing once exposure is identified.
Pass-through entities and the Georgia PTE election
Many companies in the corridor are S corporations or partnerships rather than C corporations. For them, the income is taxed on the owners’ returns, which means multistate activity creates filing obligations for the owners as well as the entity. States often require withholding or composite returns for nonresident owners.
Georgia allows eligible partnerships and S corporations, with ownership requirements for S corporations, to make an annual election to pay Georgia income tax at the entity level. The election was designed as a workaround to the federal limit on deducting state and local taxes. The 2025 federal tax law raised that limit to $40,000 for 2025 and $40,400 for 2026, with 1% annual increases through 2029, but the higher limit phases down for taxpayers with modified adjusted gross income above $500,000 for 2025, or $505,000 for 2026, and cannot fall below $10,000. It returns to $10,000 after 2029. For many owners of profitable companies, the entity-level election still produces a meaningful federal deduction. It is an annual decision, and it should be modeled with the owners’ full tax picture rather than made by default.
Is the entity still the right one?
Growth across state lines is often the moment to revisit entity choice. A flat 21% federal corporate rate can be attractive for a business that reinvests its earnings, but profits distributed as dividends are taxed again at the shareholder level. Pass-through status avoids that second layer but pushes multistate complexity onto every owner. There is no universal answer, and changing entity status has its own tax consequences, so the analysis belongs in a tax planning engagement rather than a filing season conversation.
Signs your company needs a multistate review
- Employees working remotely in states where the company has never filed.
- Sales into another state that have grown past a few hundred thousand dollars.
- Inventory held in a third-party warehouse or fulfillment center outside Georgia.
- A new service line, subscription product or software offering.
- Owners who live outside Georgia.
- A sale of the business, an outside investment or a bank refinancing on the horizon.
A nexus and multistate tax review identifies where filing obligations exist, estimates any exposure from past years, and sets out the cleanest way to come into compliance, which in some states can include voluntary disclosure programs that limit look-back periods and penalties.

Frequently asked questions
What is Georgia’s corporate income tax rate for 2026?
Georgia’s corporate income tax rate is tied to the state’s flat individual income tax rate, which is 4.99% for tax years beginning on or after January 1, 2026. Corporations may also owe Georgia’s separate net worth tax.
Does P.L. 86-272 protect a service company from state income tax?
No. Public Law 86-272 only protects businesses whose in-state activity is limited to soliciting orders for tangible personal property that are approved and shipped from outside the state. Services, software as a service and other intangibles are not covered.
How does Georgia apportion corporate income?
Georgia generally uses a single-factor formula based on gross receipts. The percentage of a company’s gross receipts sourced to Georgia determines the percentage of its apportionable income that Georgia taxes.
Is the Georgia pass-through entity tax election still worth making?
Often, yes. The federal deduction limit for state and local taxes increased under the 2025 tax law, but it phases down for higher-income taxpayers. For many owners of profitable S corporations and partnerships, paying Georgia tax at the entity level still produces a federal deduction that would otherwise be limited. The election should be modeled each year.
