Most common questions
How much will I owe in federal taxes?
Federal taxes use progressive brackets: 10%, 12%, 22%, 24%, 32%, 35%, 37% (2024). You pay each rate only on income in that bracket. Example: $60,000 income pays 10% on first $11,000, 12% on next $33,725, 22% on remainder. Effective rate is much lower than marginal rate.
Itemized vs standard deduction - which to use?
Use whichever is higher. Standard deduction 2024: $14,600 (single), $29,200 (married filing jointly). Itemizing may benefit those with: large mortgage interest, high state/local taxes (capped at $10,000), significant charitable donations, major medical expenses. Most taxpayers now use standard deduction.
What are the best ways to reduce my tax bill?
Legal strategies: 1) Maximize 401k contributions ($23,000 limit), 2) Contribute to traditional IRA ($7,000 limit), 3) Use HSA if eligible ($4,300 individual, $8,550 family), 4) Claim all eligible deductions/credits, 5) Tax-loss harvesting for investments, 6) Timing of income/deductions.
What's the difference between tax deductions and credits?
Deductions reduce taxable income (save you your marginal tax rate). Credits reduce taxes owed dollar-for-dollar (more valuable). Example: $1,000 deduction saves $220 if you're in 22% bracket; $1,000 credit saves $1,000. Credits include Child Tax Credit, Earned Income Credit, education credits.
When are estimated taxes required?
Quarterly payments are typically required if you expect to owe $1,000+ and haven't paid 90% of current year's tax (or 100% of last year's if income >$150K). Common for: self-employed, contractors, significant investment income, rental income. Due dates: April 15, June 15, September 15, January 15.
How do state taxes affect my total tax bill?
State income tax rates vary: 0% (TX, FL, WA, etc.) to 13.3% (CA). Some states tax only investment income. Consider total tax burden when relocating. State/local tax deduction capped at $10,000 federally, making high-tax states more expensive for high earners.
What records should I keep for taxes?
Keep for 3-7 years: W-2s, 1099s, receipts for deductions, bank statements, investment records, business expenses, charitable donation receipts, medical expense receipts. Digital storage recommended. IRS can audit up to 3 years back (6 years if major underreporting).
DIY taxes vs professional - what to consider?
DIY may work for: simple situations (W-2 income, standard deduction), those comfortable with tax software. Professional help may benefit: self-employed, rental property owners, complex investments, major life changes, itemizing deductions, or when potential tax savings exceed professional fees ($200-500+ typical cost).
