CPA & Tax Services in Charleston, SC
Haigler CPA Group is a Charleston CPA firm. The office is on Wappoo Drive on James Island, a few minutes from downtown across the Wappoo Cut, and the practice serves business owners, property investors and families across the Charleston area.
A local firm, and what that is worth
Being local is not, by itself, a tax qualification. What it does mean is that the person who prepares your return files South Carolina returns constantly, has seen how the Charleston rental market shows up on a Schedule E, and can meet you without a flight being involved.
Matthew Haigler grew up in Mount Pleasant and is a Certified Public Accountant, licensed in South Carolina since 2022 under license number 10843, with a Master of Professional Accountancy (MPAcc) from Clemson University. His background is in corporate tax, real estate partnerships and high-net-worth individuals — the sort of work that teaches you where multi-state exposure hides.
What Charleston clients most often bring us
Owner-operated businesses
Charleston runs on small businesses — hospitality, trades, professional services, marine and tourism-adjacent companies. Most are pass-through entities where the business return and the owner's personal return are one tax picture split across two forms, and where entity choice quietly decides the self-employment tax bill.
Rental and short-term rental property
Charleston's rental market brings tax questions that a general preparer meets rarely: passive activity limits, depreciation, the short-term rental participation rules, and 1031 exchanges when a property turns over. Short-term rentals here also sit inside a local regulatory layer — the City of Charleston, Folly Beach, Isle of Palms and Charleston County each set their own permit rules and accommodations levies, and those rules change. Confirm the current requirements for your specific address before you rely on them.
People who moved here
Relocation years are the ones that go wrong quietly. A part-year return in two states, income earned before and after the move, and a former state that takes an active interest in when residency actually changed — it is worth filing that year correctly rather than cheaply.
IRS notices and back taxes
Audits, penalty notices and unfiled years get handled directly with the IRS on your behalf, along with South Carolina Department of Revenue matters, which run their own process and are not resolved by settling federally.
South Carolina, specifically
- South Carolina levies a state income tax; the rate schedule has been reduced in recent years, so plan against the current year's schedule rather than a remembered rate.
- Property held as a rental is assessed differently from an owner-occupied residence in South Carolina, which affects the carrying cost of an investment property.
- Accommodations taxes and short-term rental permits are set locally and vary between the City of Charleston, the beach municipalities and unincorporated Charleston County.
Where we work
Charleston is the only office. Mount Pleasant and Summerville are service areas rather than second locations, and clients there are served from here — in person by appointment, or virtually. Documents move through the secure client portal, so most engagements never require a drive.

South Carolina and the Charleston area
State filings, local licenses, property tax and what is different about doing business here.
Does South Carolina have a state income tax?
Yes, with graduated rates and its own return, and residents report income from all sources while non-residents report income sourced here. Rates and brackets are set by the state and adjust over time, so we apply the current year rather than a remembered figure. Charleston.
Do I need a South Carolina business license?
Business licenses in South Carolina are generally municipal or county rather than state, so the answer depends on where you operate — and a business working across jurisdictions can need more than one. See Summerville, where the address does not tell you the jurisdiction.
How do I know which jurisdiction I am in near Summerville?
You often cannot tell from the mailing address. Summerville spans more than one county and many addresses sit outside the town limits, which changes the licensing, the millage and who you file with. That is set out on the Summerville page.
What is the 4 percent legal residence rate?
South Carolina assesses an owner-occupied legal residence at a lower ratio than other property, and it must be applied for rather than granted automatically. Missing the application is a quiet and recurring overpayment — see Summerville.
Do I pay property tax on business equipment in South Carolina?
Business personal property is generally subject to local property tax, with an annual return listing what you own. It is easy to overlook when the business has no real estate, and it is not forgiven for having been forgotten.
Do I need a permit for a short-term rental in Mount Pleasant?
Mount Pleasant regulates short-term rentals with a permit alongside a business license and a certificate, and the number available has been capped and waitlisted. It is a local question with real limits — Mount Pleasant.
What is the long-term rental licensing trap in Mount Pleasant?
Owners renting several units long-term can fall into a licensing requirement they did not expect, separate from short-term rental rules. The threshold catches ordinary landlords — the detail is on the Mount Pleasant page.
Do you have an office in Mount Pleasant or Summerville?
No. Charleston is the only office, at 2012 Wappoo Drive on James Island, and both areas are served from there in person or virtually. Mount Pleasant and Summerville explain what that means in practice.
Which areas do you serve?
Charleston, Mount Pleasant and Summerville, with the office in Charleston. Federal work is not geographically limited, and remote meetings make the practical radius wider than the list — Charleston, and the areas we serve page sets out which is an office and which is a service area.
Does South Carolina tax pass-through business income?
Income flows to owners and is reported on their South Carolina returns, and the state has its own entity-level filings and an elective regime that can change where the tax is paid. Whether the election helps depends on the facts — business tax.
How do I register a business with the state?
Registration with the Secretary of State for the entity, with the Department of Revenue for tax accounts, and separately with your municipality for a license. They are three different steps and doing only the first is the most common gap we see.
What is MyDORWAY?
The South Carolina Department of Revenue's online system for filing and paying state taxes. Most state accounts are managed through it, and access is worth setting up before a deadline rather than during one.
Does South Carolina follow federal tax law?
It conforms to the federal code in many respects with its own modifications, and the conformity date and the adjustments change. A federal change is therefore not automatically a state change, which is one reason a state return is not just a copy.
I moved to South Carolina this year. How do I file?
Generally a part-year return here and one in the state you left, with income allocated by residency period and by source. Retirees and remote workers meet this constantly, and the date residency changed does real work — personal tax.
I live in South Carolina but work in another state. Who taxes me?
Usually the state where the work is performed taxes the income and your resident state gives a credit, but the rules are not uniform and remote work has complicated them. It is worth checking rather than assuming your employer set it up correctly.
Does South Carolina have a sales tax on services?
South Carolina taxes tangible personal property broadly and certain enumerated services rather than services generally, which is why the retail-versus-real-property question matters so much for the trades — see construction.
What are accommodations taxes in Charleston County?
Short-term accommodations attract state charges plus county and municipal layers, and platforms collect some of it but not always all of it. The gap is the owner's problem, not the platform's — real estate investors.
Is South Carolina a good state for a small business tax-wise?
It has its own rate structure, its own credits and a local licensing layer that surprises people arriving from states without one. Whether it is favorable depends on the business; what matters more is that the local obligations are actually met. Small business.
Do I need to file a South Carolina return if I only have rental property here?
Income from property located here is generally taxable here, which usually means a non-resident return, with your home state typically giving a credit. Out-of-state owners of Charleston-area rentals face this every year — rental real estate.
What is the Charleston-area tax question you get most often?
Short-term rentals — the interaction of permits, business licenses, accommodations taxes and the federal treatment of a property with a short average stay. It is four separate rule sets that people meet as one problem. Real estate investors.
Are hurricane or storm losses deductible?
Personal casualty losses are limited to federally declared disaster areas under current rules, with their own calculation and election as to which year to claim them. Business property is treated differently. It is one to work through rather than assume.
Do you understand the local business license process?
It is one of the recurring reasons Charleston-area businesses come in — the municipal layer is real, the thresholds are local, and it is separate from state registration. See Charleston, Mount Pleasant and Summerville.
Can you help a business relocating to Charleston?
Yes — registration, the local license layer, state accounts, and the multi-state questions that follow a move rather than end with it. The first conversation is the place to map it: schedule one.
Where can I read more about your work in the Charleston area?
The Charleston page covers the office and what South Carolina changes, and the news section carries longer pieces on entity choice, exchanges, audit letters and monthly bookkeeping.
Does my business have to collect South Carolina sales tax?
If you make retail sales in South Carolina, almost certainly — including online-only sales, and it starts on the first sale rather than at some level of profit. It needs a Retail License, and the rate you charge is the rate for the delivery address, because counties add local option taxes by referendum. Out-of-state sellers get pulled in once their revenue into the state passes the threshold: what a small business actually has to do.
