Reduce your gross income
Pension contributions. Contribute to a 401(k) or similar retirement plan. You reduce your taxable income and may also qualify for matching contributions from your employer. Plus, you’re taking a great step towards a secure retirement!
Deferred income. If you have some flexibility in how you get paid, defer as much of your income as you can into the new year.
Flexible spending accounts. If your employer has a plan that allows you to save for child-care or uninsured medical expenses, sign up! The money comes out of your check before taxes, so it reduces your taxable income.
Tax-free job perks. See if you can take part of your income in the form of tuition paid by your employer. This reduces your gross income, and you’ll invest in yourself by learning new skills. Public transportation passes worth up to $65 a month are also tax-free.
Business expenses. Develop an at-home business to increase your deductible expenses. You don’t have to make a profit for your expenses to be deductible, and any "loss" reduces your taxable income.
