Roth Wizards helps parents employ their children, track real work, and fund custodial Roth IRAs. Every dollar your child earns can grow tax-free for decades, potentially reaching millions by retirement. Why Parents Love Roth Wizards: Save on Taxes — Deduct your child's wages as a business expense (if you have a business) Build Wealth — Every dollar earned can go into their Roth IRA, growing tax-free Stay Compliant — Built on IRS Publication 15 and IRC Section 3121(b)(3)(A) CPA-Ready — Generate W-2 and W-3 forms, plus year-end audit binders Track Everything — Log jobs, hours, photos, and payments in one place Perfect For: Business Owners — Hire your kids for real business tasks (marketing, photography, data entry) and deduct wages Household Work — Pay for legitimate household projects (yard work, photo organization, tutoring siblings) even without a business Tax-Smart Families — Turn "helping out" into documented earned income Key Features: Job Logging — Log real work with photos, hours, and pay rates Photo Documentation — Attach before/after photos to prove work was substantial Payment Tracking — Track which jobs are paid and how much you owe Roth Contribution Limits — See exactly how much you can contribute each year (up to $7,500 for 2026) Tax Forms — Generate W-2 and W-3 forms automatically CPA Exports — One-click downloads with all documentation your accountant needs EIN Support — Get help applying for your Employer Identification Number Smart Suggestions — Age-appropriate job ideas with fair market rates How It Works: Pick a job your child can help with (business or household) Log the time and pay them Match that income with a custodial Roth contribution Relax—Roth Wizards stores every detail for tax time Real Example: Pay your teen $3,000 for product photography. If you're in a 30% tax bracket, you save ~$900 in taxes. That same $3,000 goes into their Roth IRA and can grow to over $3M by age 65—all tax-free. Compliance Built-In: Every workflow aligns with IRS guidance on hiring your own children. We help you: Document real work (not routine chores) Track earned income for Roth IRA eligibility Generate proper payroll documentation Stay within contribution limits No Business? No Problem. Even without a business, your kids can earn real income for legitimate household work. Every dollar they earn can go toward a Roth IRA—building the same tax-free wealth. The only difference? You won't get a tax deduction, but your child still gets a financial future. Simple Pricing: Choose the plan that fits your family. Many parents save hundreds in taxes each year—often covering the cost in one weekend of documented work. Important: Roth Wizards is a record-keeping tool and does not provide tax, legal, or financial advice. Consult a qualified CPA or tax professional for guidance specific to your situation.
