How SARS treats US LLCs
South African Revenue Service (SARS) generally treats US single-member LLCs as transparent for SA tax purposes. LLC operating income flows through to your annual SA income tax return and is taxed at progressive SA rates.
SA exchange control rules (SARB) apply to outward and inward USD flows. Consult an SA tax/exchange specialist for clean structure, especially for ongoing LLC operations across the SA-US borders.
