Input all income sources - W-2 wages, business income (Schedule C self-employment), long-term capital gains (0/15/20% preferential rates), qualified dividends (same rates as LTCG), and other income (interest, rental, royalties) to model complete tax picture. Calculate adjusted gross income (AGI) by applying above-the-line deductions (reduce AGI directly): Traditional IRA/401(k) contributions ($23,000 limit 2024, $7,500 catch-up 50+), HSA contributions ($4,150 individual/$8,300 family, $1,000 catch-up 55+), self-employed health insurance premiums (100% deductible), student loan interest deduction ($2,500 max, phaseout $75k-90k single/$155k-185k MFJ), educator expenses ($300), and self-employment tax deduction (50% of SE tax = 7.65% effective reduction). Model standard deduction vs itemized deductions (below-the-line, reduce taxable income): 2024 standard deduction $14,600 single/$29,200 married filing jointly/$21,900 head of household/$14,600 married filing separately, compared to itemized deductions total (mortgage interest on $750k-1M loans up to $10k-12k deductible, state and local taxes SALT cap $10,000 combined property+income/sales, charitable contributions 60% AGI limit cash/30% appreciated assets, medical expenses exceeding 7.5% AGI, unreimbursed employee expenses subject to 2% AGI floor). Compare 2024 federal tax brackets across filing statuses - Single ($11,600 10% / $47,150 12% / $100,525 22% / $191,950 24% / $243,725 32% / $609,350 35% / over 37%), Married Filing Jointly ($23,200 10% / $94,300 12% / $201,050 22% / $383,900 24% / $487,450 32% / $731,200 35% / over 37%), calculate federal tax liability in each bracket (example: $100,000 single taxable = $11,600×10% $1,160 + $35,550×12% $4,266 + $52,850×22% $11,627 = $17,053 federal, but after standard deduction $14,600, actual taxable = $85,400, actual tax = $14,605 = 14.6% effective on $100k gross), then apply tax credits (reduce tax dollar-for-dollar, more valuable than deductions): refundable credits (Child Tax Credit $2,000 per child under 17, phaseout $200k/$400k, up to $1,700 refundable; Earned Income Tax Credit $600-$7,430 based on income/children, phaseout $17k-$63k; American Opportunity Credit $2,500 education, 40% refundable = $1,000; Additional Child Tax Credit refundable portion) vs non-refundable credits (Lifetime Learning Credit $2,000 education, Child and Dependent Care Credit $600-$2,100, Retirement Savings Contributions Credit Saver's Credit 10-50% up to $2,000/$4,000, phaseout $38k/$76k, Energy Efficiency Credit 30% solar/geothermal up to limits). Calculate marginal tax rate (tax rate on next/last dollar earned) vs effective tax rate (total taxes / total income) - example: $100,000 income single filer, marginal rate = 22-24% (top bracket), effective rate = 15-18% (average across all brackets + FICA + state). Model true tax burden across income levels (2025 estimates): $50,000 single = 8-12% federal ETR + 7.65% FICA + 3-5% state = 18-25% total ETR; $100,000 = 14-16% federal + 7.65% FICA + 5-7% state = 26-31% total; $200,000 = 18-20% federal + 4.8% FICA (Medicare only on $31,400 excess) + 7-9% state = 29-34% total; $500,000 = 24-26% federal + 2.2% FICA (Medicare 1.45% + NIIT 3.8% on investment income) + 9-11% state = 35-40% total; $1,000,000+ = 26-28% federal (lower if mostly LTCG at 20%) + 2.35% FICA (Medicare + NIIT) + 10-13% state = 38-43% total. Analyze self-employment tax impact (Schedule SE): Self-employed pay both employee + employer FICA = 15.3% total (12.4% Social Security on first $168,600 + 2.9% Medicare unlimited), but can deduct 50% of SE tax above-the-line = net 14.13% effective SE tax, plus 0.9% Additional Medicare Tax on earnings above $200k/$250k = 15.03% total on high earners (example: $150,000 net business income = $21,195 SE tax, $10,597 deductible, net burden $10,598 = 7.07% effective after deduction, plus 15-22% federal income tax = 22-29% combined vs W-2 employee 15-22% federal only). Compare Additional Medicare Tax (0.9% on wages/SE income above $200k single/$250k MFJ, no employer match) + Net Investment Income Tax NIIT (3.8% on investment income dividends/interest/capital gains/rental/royalties for MAGI above same thresholds, total 4.7% Medicare surtax on high earners). Model Alternative Minimum Tax AMT interaction (26-28% flat tax on AMT income AMTI, exemption $85,700 single/$133,300 MFJ phaseout $609,350/$1,218,700, add-backs for SALT/mortgage/depreciation, parallel calculation, pay higher of regular tax or AMT, can increase effective rate 2-5% for $200k-$1M earners with large deductions). Project tax savings strategies to reduce ETR: Max 401(k) $23,000 = save $5,060-$8,510 federal tax at 22-37% bracket + $1,760 FICA + $1,150-$3,013 state = $7,970-$13,283 total savings (34.7-57.8% effective reduction on contribution); HSA $8,300 family = save $1,826-$3,071 federal + $636 FICA + $415-$1,079 state = $2,877-$4,786 (34.7-57.7%); Harvest tax losses to offset gains $3,000/year ordinary income = save $660-$1,110 federal + $150-$390 state = $810-$1,500; Bunch itemized deductions alternating years (2-year $20k charitable vs annual $10k, cross $29,200 MFJ standard in year 1 only = save $2,200-$3,700 extra); Qualified Business Income QBI deduction 20% pass-through income up to $191,950/$383,900 limits = save 20% × 22-37% = 4.4-7.4% ETR reduction on business income; Roth conversions in low-income years (retire early, between jobs, fill 12-22% brackets before RMDs push to 24-32% = 2-10% arbitrage). Calculate state tax impact by jurisdiction (2024 rates): 9 no-income-tax states (AK/FL/NV/NH/SD/TN/TX/WA/WY = 0% ETR boost), low-tax states (AZ 2.5%, CO 4.4%, NC 4.5%, UT 4.65% = 2-5% total ETR), medium-tax (GA 5.75%, IL 4.95%, MA 5%, VA 5.75% = 4-6% total ETR), high-tax (CA 1-13.3% progressive, NY 4-10.9%, NJ 1.4-10.75%, OR 4.75-9.9% = 6-13% total ETR for high earners), plus local taxes (NYC 3.078-3.876%, San Francisco 0.38-1.5%, Philadelphia 3.79% = add 1-4% to state ETR). Model tax bracket progression (2024 federal): 10% bracket $0-$11,600 single / $0-$23,200 MFJ (effective max 10%), 12% bracket $11,600-$47,150 / $23,200-$94,300 (effective max 11.5%), 22% bracket $47,150-$100,525 / $94,300-$201,050 (effective max 17.1%), 24% bracket $100,525-$191,950 / $201,050-$383,900 (effective max 20.4%), 32% bracket $191,950-$243,725 / $383,900-$487,450 (effective max 21.9%), 35% bracket $243,725-$609,350 / $487,450-$731,200 (effective max 26.9%), 37% bracket $609,350+ / $731,200+ (effective approaches 37% for $10M+ income). Real-world ETR examples (2024): Single $75,000 gross (W-2 only, standard deduction, no kids) = $8,990 federal (after $14,600 deduction on $60,400 taxable) + $5,738 FICA + $3,750 state (5%) = $18,478 total / $75,000 = **24.6% total ETR** (12% marginal, 12.0% federal ETR, 7.7% FICA ETR, 5.0% state ETR); Married $150,000 gross (dual income, 2 kids, standard deduction, $4,000 Child Tax Credit) = $13,058 federal (after $29,200 deduction on $120,800 taxable = $17,058 raw tax - $4,000 CTC) + $11,475 FICA + $7,500 state (5%) = $32,033 total / $150,000 = **21.4% total ETR** (22% marginal, 8.7% federal ETR, 7.7% FICA ETR, 5.0% state ETR); Self-employed $200,000 (Schedule C, max 401k $69,000 = $23k employee + $46k employer match on $200k income, $8,300 HSA, $10,000 deduction SE tax) = $25,741 federal (after above-line deductions AGI $152,700, standard $14,600, taxable $138,100) + $24,498 SE tax (but $12,249 deductible, net $12,249) + $10,000 state (5%) = $47,990 total / $200,000 = **24.0% total ETR** (24% marginal, 12.9% federal ETR, 6.1% net FICA ETR after deduction, 5.0% state ETR), but pre-401k income $269,000 would have 32.2% ETR = **8.2% ETR reduction** from retirement savings.
