Locksmith Business Estimated Taxes: Emergency Calls, Cash Payments, and Quarterly Planning

Estimated tax planning for locksmiths:

• All revenue is taxable. Cash, check, Venmo, Zelle, credit card, PayPal. Emergency lockout calls paid in $100 bills at 2 AM are taxable income. The IRS cross-references 1099-K reports from Square, Stripe, and other processors with the business’s reported gross receipts.
• Set-aside rate: 25-30% of net profit (after all deductible expenses). For a sole proprietor earning $80,000 net, this means approximately $20,000-$24,000 in annual tax.
• Quarterly due dates: April 15, June 15, September 15, January 15.
• Tracking cash. Use a daily cash log (date, job description, amount received, customer name). Deposit all cash within 1-2 days. Avoid the temptation to spend cash without recording it. The IRS uses bank deposit analysis to identify unreported cash income during audits.
• 1099-K threshold. Payment processors report on 1099-K when aggregate payments exceed $600 (current threshold). If Square reports $70,000 and the locksmith reports $72,000 total, the IRS won’t flag it. If Square reports $70,000 and the locksmith reports $55,000, an audit is coming.

Per-job set-aside approach:

• Standard residential call ($120): set aside $35
• Automotive lockout ($150): set aside $45
• Transponder key ($200): set aside $60
• After-hours emergency ($300): set aside $100
• This automatically scales with revenue

Seasonal patterns: Locksmith revenue is less seasonal than outdoor services but has patterns (monthly variance typically 10-20%). Emergency lockouts spike during holidays (people locked out of homes, car lockouts after parties), and commercial lock changes spike in January (new year, new tenants, security updates). Equal quarterly payments work for most locksmiths. Equipment replacement years (new transponder programmer, key machine upgrade) create recurring deductions that lower payments in upgrade years.
