10 Legal Ways to Pay Less Taxes

Paying taxes is a normal part of earning money—but overpaying isn’t. The truth is, many people end up paying more tax than necessary simply because they don’t understand how to legally reduce it.

This guide is designed to help you keep more of your income without breaking any rules. Whether you’re employed, freelancing, or running a small business, these practical strategies can make a real difference.

This is the single most powerful tax move for most people.

When you contribute to a traditional 401(k) or IRA, that money comes off your taxable income. If you earn €60,000 and contribute €5,000, you are taxed on only €55,000.

For 2025 (US limits):

• 401(k): Up to €23,000 per year (€30,500 if over 50)
• Traditional IRA: Up to €7,000 per year (€8,000 if over 50)

What are the best ways to reduce taxable income for high earners? Maxing retirement accounts is number one. Every euro contributed saves you your marginal tax rate (22–37%).

HSAs are triple tax-free. You contribute pre-tax money. It grows tax-free. You withdraw tax-free for medical expenses.

For 2025: Up to €4,150 for individuals, €8,300 for families. Plus an extra €1,000 catch-up if over 55.

The secret: You can invest HSA money like a retirement account. Save medical receipts now. Reimburse yourself decades later – tax-free.

Low to moderate income? The government gives you a tax credit just for saving for retirement.

Worth up to €1,000 (€2,000 for married couples) – and it is a credit, not a deduction. Credits reduce your tax bill euro for euro.

Income limits (2025): Approximately €36,500 for singles, €73,000 for married couples filing jointly.

If you earn money outside your main job, you may be able to deduct related expenses.

Examples:

• Software or tools
• Internet costs
• Home office expenses

Important:

Only claim expenses that are directly related to your income.

If you pay student loan interest, you can deduct up to €2,500 per year – even if you do not itemize deductions.

Income limits apply (phase-out starts around €75,000 for singles, €155,000 for married couples). But most borrowers qualify.

Childcare is expensive. A Dependent Care Flexible Spending Account lets you set aside pre-tax dollars for daycare, summer camp, or after-school programs.

For 2025: Up to €5,000 per household. That is €5,000 of childcare expenses paid with untaxed money. If your marginal tax rate is 22%, you save €1,100.

Not all investments are taxed the same way.

Some options may offer:

• Lower tax rates
• Tax-deferred growth
• Tax-free withdrawals (depending on the system)

Smart move:

Learn how your investments are taxed before you invest.

Giving to charity feels good. It can also lower your taxes – if you itemize.

Donate cash, stock, or even household goods. Keep receipts. For donations over €250, get written acknowledgment from the charity.

Pro move: Donate appreciated stock you have held for over a year. You avoid capital gains tax and deduct the full market value. You give €10,000 of stock (bought for €4,000). No capital gains tax on the €6,000 gain. Plus a €10,000 charitable deduction.

The EITC is designed for low-to-moderate-income workers. It is a refundable credit – meaning even if you owe no tax, you get money back.

For 2025: Worth up to €7,400 for families with three or more children. Single workers without children qualify for smaller amounts.

Income limits vary by family size. Use the IRS EITC Assistant to check eligibility.

Beyond mortgage interest, homeownership offers other tax breaks:

• Property tax deduction: Deduct state and local property taxes (capped at €10,000 combined with state income tax).
• Points deduction: If you paid points to lower your mortgage rate, deduct them over the life of the loan (or all at once if refinancing).
• Home office deduction: If you are self-employed and use part of your home regularly and exclusively for business.

What home office expenses can I deduct as a self-employed person? A portion of mortgage interest, property taxes, utilities, insurance, and repairs – based on the percentage of your home used for business. Simplified option: €5 per square foot up to 300 square feet.

Bonus Strategy: Choose the Right Filing Status

Your filing status affects your tax bracket, standard deduction, and eligibility for credits.

Options:

• Single
• Married filing jointly (usually best for married couples)
• Married filing separately (rarely better, but useful for income-based student loan payments)
• Head of household (for unmarried people paying more than half the cost of keeping a home for a dependent)

Can you file head of household without a dependent? Generally no. You need a qualifying person (child, parent, or other relative) living with you for more than half the year.

This confuses many people. A deduction reduces your taxable income. A credit reduces your tax bill directly.

• €1,000 deduction at 22% tax bracket saves you €220.
• €1,000 credit saves you €1,000.

Credits are much more valuable. Prioritize credits (EITC, Saver's Credit, Child Tax Credit) over deductions whenever possible.

You do not need to do all ten. Pick 3–4 that fit your situation.

For employees with a retirement plan at work: Focus on 401(k) contributions, HSA (if eligible), and student loan interest deduction.

For self-employed workers: Retirement accounts (SEP IRA or Solo 401(k)), home office deduction, health insurance deduction, and business expenses.

For low-to-moderate-income workers: Saver's Credit, Earned Income Tax Credit, and retirement contributions.

Paying less tax isn’t about avoiding taxes—it’s about understanding how the system works and using it correctly.

If you:

• Stay informed
• Track your finances
• Use available deductions and credits

You can legally reduce your tax burden and keep more of your hard-earned money.
