Small companies’ income tax obligations differ substantially from large corporation requirements across four key dimensions. Specifically, C-corporations with total assets under $10 million qualify for the IRS’s correspondence examination program rather than in-person field audits. Additionally, small businesses may use the cash basis accounting method under IRC §448 if average annual gross receipts remain below the $29 million 2026 indexed threshold. Furthermore, small corporations can immediately expense up to $1,220,000 in qualifying property under §179 — a larger proportional deduction than the 20% bonus depreciation rate delivers for modest capital budgets. Conversely, small corporations completely avoid CAMT exposure, Pillar Two obligations, and transfer pricing complexity — making their compliance burden substantially lower per dollar of revenue despite the identical statutory rate.
