Holding dual CTEC tax-preparer and NACPB bookkeeper certifications, Cardiff Tax Pros in Encinitas operates year-round from Encinitas Boulevard near the Interstate 5 corridor. The firm's small-business bookkeeping runs on QuickBooks Online at Gold-level ProAdvisor certification, a cloud-based platform that freelancers and startup tenants at coworking spaces such as Kiln use to maintain audit-ready records between tax cycles. Return preparation spans 1040 individual filings, 1120S S-Corporation returns, and Schedule C sole-proprietorship schedules, with year-round availability rather than seasonal-only filing windows. Nonprofit clients receive Form 990, 990-EZ, California Form 199, and RRF-1 preparation — a filing combination specific to California charitable organizations maintaining state and federal tax-exempt status. Payroll management covers quarterly EDD filings, year-end W-2 and 1099 distribution, and California sales-tax compliance, with the same quarterly withholding cadence that drives payroll schedules at production operations including Avid Studios. Highest-complexity engagements include multi-state sales-tax nexus analysis, S-Corporation reasonable-compensation determinations, and retroactive bookkeeping cleanup for businesses transitioning from cash-basis to accrual-basis accounting.
