Understanding your tax landscape can help identify legal strategies to reduce your tax bill. Federal and state tax laws offer various opportunities for W-2 employees (those with regular job income) to lower taxable income and manage tax on investments like Bitcoin. This guide breaks down strategies at the federal and state level, highlights deductions and credits for individuals with W-2 income, explains tax-advantaged accounts (HSAs, FSAs, 401(k)s, IRAs), and outlines ways to minimize taxable events related to Bitcoin. It also covers special considerations for high-tax states (e.g. California, New York) and provides tips on record-keeping to stay compliant with IRS rules.
Federal Income Tax Reduction Strategies
Maximize Deductions
Every U.S. taxpayer can claim a standard deduction (a fixed amount that reduces taxable income) or choose to itemize deductions (listing specific deductible expenses). W-2 employees should compare the two and take whichever is higher:
Standard Deduction: For most people, the standard deduction shelters a significant portion of income from tax. You don’t need to show any expenses to claim it – it’s automatic.
Itemized Deductions: If you have large deductible expenses (commonly home mortgage interest, state/local taxes, charitable contributions, and medical expenses), itemizing may yield a bigger deduction. For example, you can deduct mortgage interest on a primary home loan (up to certain limits) and property taxes. State and Local Taxes (SALT) – including state income tax and local property tax – can be deducted, but the total SALT deduction is capped at $10,000 per year. This cap especially affects those in high-tax states like NY or CA who pay substantial state income/property taxes. If your itemizable expenses don’t exceed the standard deduction, stick with the standard deduction; if they do, itemizing can reduce your taxable income further.
Utilize Tax Credits
Tax credits directly reduce the tax you owe, and many are designed for individuals with regular earned income (W-2 wages). Unlike deductions (which reduce income), credits cut your actual tax dollar-for-dollar. Key credits for employees include:
Child Tax Credit (CTC): Worth up to $2,000 per qualifying child under 17, subject to income phase-outs.
Child and Dependent Care Credit: If you pay for daycare or dependent care so you (and your spouse) can work, you may get a credit for a percentage of those costs. For one dependent, up to $3,000 of expenses can qualify (double for two or more dependents), with a credit of up to 35% of those expenses, depending on your income.
Education Credits: The American Opportunity Tax Credit (AOTC) provides up to $2,500 per year for eligible college expenses (with up to $1,000 refundable). The Lifetime Learning Credit offers up to $2,000 for tuition or courses to improve job skills.
Retirement Saver’s Credit: Lower- to moderate-income employees who contribute to a 401(k) or IRA might qualify for the Saver’s Credit, which is an extra credit (10%–50% of your retirement contributions up to $2,000) if your income is below certain thresholds.
Earned Income Tax Credit (EITC): A refundable credit for eligible low-to-moderate income workers; if your income is within the limits and you have qualifying children, it can be a sizable benefit.
Above-the-Line Adjustments
W-2 employees can also reduce Adjusted Gross Income (AGI) through certain adjustments that don’t require itemizing. For example, if you paid interest on student loans for yourself, your spouse, or a dependent, you can deduct up to $2,500 of that student loan interest even while taking the standard deduction. Educator expenses (up to $300 for teachers’ classroom supplies) and alimony paid (for older divorce agreements) are other adjustments that lower AGI. A lower AGI not only directly reduces taxable income but can also help you qualify for the credits above (many credits phase out at higher incomes).
Strategic Timing
Where possible, time your income and deductible expenses to your advantage. For example, if you’re near the threshold of being able to itemize, you might bunch deductions into one year. This could mean prepaying an extra mortgage payment or property tax installment in December, or grouping charitable donations in one calendar year, so that your itemized deductions exceed the standard deduction for that year. Then in the next year, you might take the standard deduction. This way, over a two-year period, you maximize total deductions by alternating between itemizing and the standard deduction.
Contributing to Tax-Advantaged Accounts
Employer Retirement Plans (401(k), 403(b), etc.)
Contributing to a traditional 401(k) through your employer reduces your W-2 taxable wages. Money you contribute pre-tax is not included in your income on your Form W-2, which means you don’t pay federal income tax on it (and usually not state tax either). For example, if you divert $19,500 into your 401(k), that’s $19,500 less of your salary subject to tax. In 2024, employees can contribute up to $23,000 to a 401(k) (or $30,500 if age 50+) pre-tax.
Health Savings Account (HSA)
If you’re enrolled in a qualified high-deductible health plan, you can contribute to an HSA. HSA contributions are above-the-line deductions, meaning they reduce your AGI even if you don’t itemize. HSAs have a triple tax advantage: contributions are tax-free, growth (interest or investment earnings) is tax-free, and withdrawals are tax-free if used for qualified medical expenses.
Managing Bitcoin and Cryptocurrency Taxes
Hold for the Long Term
If you’ve held Bitcoin for more than one year before selling or exchanging, you qualify for long-term capital gains tax rates, which are significantly lower than ordinary income rates.
Use Specific Identification for Cost Basis
If you bought Bitcoin at different times and prices, you can potentially choose which units to sell to maximize tax benefits.
Harvest Tax Losses
The crypto market is volatile, which isn’t always bad news at tax time. If some of your Bitcoin or other crypto investments are down, you can sell them to realize a capital loss, which can offset your other capital gains.
Donate Appreciated Bitcoin to Charity
If you have Bitcoin that has gone up substantially and you’re inclined to give to charity, consider donating the Bitcoin directly instead of selling it for cash and donating cash. More on that here:
Using Bitcoin for Charitable Giving Trusts
Leveraging long-term, highly appreciated Bitcoin to establish a charitable giving trust can be a transformative way to support causes you care about while achieving significant tax benefits. By donating Bitcoin directly to a charitable entity, you can potentially eliminate capital gains taxes and receive a fair market value deduction, thereby maximizing…
Record Keeping and IRS Compliance
Staying on the right side of the IRS requires good record keeping. This is especially true with cryptocurrency, but it applies to your income and deductions as well.
Document Your Crypto Transactions
The IRS expects detailed records for each taxable cryptocurrency event. You should maintain a log that includes the date and time you acquired the coins, how much you acquired and at what cost (your cost basis), the date and time you sold or disposed of them, and what you received in exchange.
Track Contributions to Accounts
Save year-end statements for your 401(k) or IRA contributions, HSA funding, and FSA elections.
