Getting to Grips with the Basics
The U.S. tax system is built on the principle of "taxes are paid in the year in which income is earned." Thus, deductions, credits, and deferrals taken now impact the tax return you submit for the current year. Once the calendar year concludes, it’s the last chance to reduce your taxable income for that year. When the year ends, the opportunity closes and you have to wait until the next filing cycle to benefit from new actions.

Essential Year-End Relief Tools
1. Increase Retirement Contributions
• 401(k) or 403(b) employers’ plans: Contribute the maximum amount allowed ($23,500 for 2024), with an additional $7,500 catch‑up if you’re 50 or older.
• Traditional IRA: If you qualify, you can contribute up to ($6,500|$7,500 if 50+). Contributions may be tax‑deductible depending on your income and participation in an employer plan.
• Converting to a Roth IRA: If you have a traditional IRA, converting to a Roth IRA can shift future tax liability to a year when you expect lower income, but the conversion is taxable in the current year. This can be strategic if you anticipate lower income later.

2. Capture Capital Losses
• Liquidating losing investments lets you offset up to ($3,000 in 2024|$1,500 for married filing separately) of ordinary income. Any remaining losses can be carried forward to future years. Match sale timing to avoid a wash‑sale (selling and buying the same security within 30 days).

3. Charitable Contributions and DAFs
• Contribute to charity before year‑end. Donations to qualified charities are deductible, and contributions to a DAF give you flexibility to distribute funds over time while still claiming the deduction immediately.
• Should you hold appreciated assets, donating them helps sidestep capital gains tax while offering a deductible basis equal to fair market value.

4. HSA Contributions
• Enroll in an HSA if you have a high‑deductible plan and contribute. Contributions are deductible, grow tax‑free, and withdrawals for qualified medical expenses are also tax‑free. The 2024 limits are ($4,150 per individual|$8,300 for families), plus a $1,000 catch‑up for those 55+.

5. Flexible Spending Accounts (FSAs) and Dependent Care Accounts
• Deposit up to the IRS maximum ($3,050 health|$5,000 dependent care in 2024).
• If funds remain unused, a short grace period or two‑month carryover may be available based on the employer plan.

6. Modify Tax Withholding or Estimated Payments
• Employ the IRS Tax Withholding Estimator to see if you’re overpaying or underpaying.
• If you’ve earned additional income or expect a large deduction, you can adjust your paycheck withholding or make an estimated tax payment to avoid a large tax bill or refund.

7. Delay Income and Speed Up Expenses
• If you control the timing of a large payment, consider deferring it into the next year.
• Prepay deductible items like mortgage interest, property tax, or business costs before year‑end.

8. Business‑Specific Strategies
• If you own a small business, consider a "Section 179" deduction to write off the full cost of qualifying equipment purchased in 2024.
• Employ the "bonus depreciation" provision to write off specific assets in full.
• If you’re a self‑employed individual, make sure you’ve paid the required self‑employment tax and have contributed to a SEP IRA or Solo 401(k) for additional retirement savings.
