INDIVIDUAL MCP TOOL

analyze_estimated_taxes

Estimated / quarterly tax & safe-harbor planner (IRC §6654) for the self-employed and S-corp owners: "How much should I send the IRS each quarter so I never owe an underpayment penalty?" From your projected self-employment / S-corp income it projects the current-year tax (self-employment tax on 92.35% net earnings, federal income tax with the optional §199A QBI deduction, NIIT, and an optional flat state tax), then computes the §6654 required annual payment — the LESSER of 90% of the projected current-year tax and the 100%/110%-of-prior-year safe harbor (110% when prior-year AGI exceeds $150,000).
