You’ve filed or extended your 2014 tax return and now it’s time to plan for next tax season. Here are five simple tax planning tips for 2015.

1. Check your withholding.
If you owed money in 2014 and weren’t self-employed, chances are that you might not be withholding enough tax from your paycheck. On the other hand, if your refund was more than a thousand dollars, you probably are withholding too much and could be getting a larger take-home check every week. Your employer withholds tax based on the information you’ve provided on your Form W-4. The more allowances you claim on Line 5, the less tax your employer withholds. The fewer exemptions you claim, the more tax is withheld.

2. Increase your retirement contributions.
Money you contribute to your 401(k), 403, or SIMPLE account reduces your taxable income, which in turn reduces your tax bill. Some employers will even match contributions to a certain extent. That doesn’t mean you should only contribute up to the match. Investing early unleashes the power of compounding interest.

3. Make HSA contributions.
If you have a high-deductible health plan, make HSA contributions through your paycheck to reduce your taxable income. Paycheck contributions (through a cafeteria or 125 plan) also reduce the amount of wages subject to FICA tax. This is great double benefit. You can make contributions outside of work, but they will only reduce your income tax.

4. Know your tax bracket.
Do you know how much of your income was taxed at 10, 15 or 20 percent? The U.S. has a progressive tax system, meaning that your income is separated into brackets and each bracket is taxed at that percent. There is no gradual increase. Once you reach the edge of the 15 percent bracket, for example, an additional dollar of income goes from being taxed at 15 percent to 25 percent. Your taxable income is reported on Line 43 of Form 1040.

5. Have a plan and seek advice.
