CPA Heather F. Austin has operated an accounting practice on La Mesa Boulevard since 2003, specializing in tax preparation for nonprofit organizations and small businesses. Form 990 preparation for nonprofits — including Schedule A public-support tests and functional-expense allocations — requires the same clean monthly financials that bookkeeping operations at Tavai Bookkeeping LLC produce for shared clients. The CPA credential from the California Board of Accountancy authorizes financial-statement reviews and compilations, supporting grant-compliance requirements under OMB Uniform Guidance for federally funded organizations. Individual tax services cover Form 1040 preparation with California Schedule CA adjustments, including state-specific treatments for retirement-income exclusions and capital-gain deferrals. The firm also prepares financials for businesses undergoing operational restructuring, producing accrual-basis statements and cash-flow analyses that inform the strategic recommendations delivered by Ranta Consulting, Inc.. Highest-tier nonprofit engagements involve Form 990 preparation with unrelated business income tax calculations on Form 990-T and compliance testing for Section 501(c)(3) private-foundation excise taxes.
