Running a small business is a daunting task, especially if your entrepreneurial strengths lie more towards designing modernist furniture than writing up a balance sheet. If you're ready to retire as a full-time CPA or corporate accountant, there are ample opportunities for a freelance career as a bookkeeper or a seasonal tax preparer.
Bookkeepers can bounce around between several small businesses, depending on their needs. Maybe one company only needs help handling payroll for 10 employees, but another company needs the whole package: accounts payable/receivable, creating financial reports, tracking investments and the like. The bulk of bookkeeping work is usually in the middle and the end of the month, leaving some time to pursue other retirement hobbies [source: Hannon].
Tax preparation is terrific work if you'd rather squeeze all of your income (and stress) into the four-month window from January through April. You can offer your services to businesses and individuals alike, charging by the hour or by the service. Keep in mind that you'll need to acquire a Preparer Tax Identification Number from the Internal Revenue Service (IRS) [source: Hannon]. You don't want to cross those guys.
