1. Job hunting expenses

Were you recently on the job hunt? If so, you probably forked over a considerable amount of cash to cover outplacement agency fees or mailing copies of your resume. Little did you know, you can possibly deduct some of those expenses.

You can deduct certain job search-related expenses, according to the IRS; but there are some rules you must follow. For example, you can't deduct these expenses if you're looking for a job for the first time.

2. Pet moving costs

Who knew there were tax breaks for pet owners?

Believe it or not, if Fido is also moving for your new job, those relocation costs could be tax deductible. For example, if your employment-related move meets IRS requirements, you might be able to deduct your pet's shipping costs.

3. Self-employment expenses

Self-employed taxpayers don't get a form W-4 and can't take advantage of certain payroll tax deductions, but they can take advantage of many of the same small-business tax deductions. For example, self-employed individuals who work from home or use their home as part of their business can treat a portion of mortgage or rental expenses, utility costs, maintenance and other expenses as tax write-offs.

Self-employed individuals can also deduct the employer-equivalent portion of their self-employment tax in figuring their adjusted gross income. Check the official IRS site to find out about the best tax deductions in this category.

4. Child and dependent care costs

If you paid for the care of a qualifying child or other dependent so that you and your spouse could work, you might qualify for the child and dependent care credit.

Tax credits are typically better than tax deductions. Whereas deductions reduce your taxable income, credits directly reduce your taxes. So, if you didn't know about the child and dependent care credit, find out if you qualify now.

5. Smoking cessation costs

Are you trying to kick your nicotine habit? Your participation in a smoking cessation program can be considered a medical tax deduction. This deduction can also apply to prescription drugs used to ease nicotine withdrawal.

6. Weight-loss expenses

No, this doesn't mean you can deduct the cost of every diet fad or trend you recently tried. Instead, this benefit is for people who have participated in weight-loss programs to combat a specific disease that their physicians diagnosed.

7. Charitable travel costs

If you're considering taking a "vacation" to volunteer, you might be able to claim a charitable contribution deduction for travel expenses you had to incur while helping out an organization.

But be careful: The IRS makes it clear that there must be "no significant element of personal pleasure, recreation or vacation in the travel." That doesn't mean you can't have fun -- but you should be "on duty in a genuine and substantial sense throughout the trip."

8. Breast surgery expenses

Although you can't typically include unnecessary cosmetic surgery as a medical expense, some cases of breast surgery can be eligible. For example, the IRS states that if you needed breast reconstruction surgery as part of cancer treatment, you can include the cost in your medical expenses.

9. Pregnancy test expenses

Yes, when filing your taxes you can also include the amount you paid for a pregnancy test in your medical expenses. It might seem like a small expense, but some people will shell out more cash for higher-priced tests.

And what about after you have the baby? You can also include breast pumps and supplies in medical expenses.

10. Wig costs

A wig can also be tax deductible as a medical expense. If the physician recommends the wig after you experienced hair loss due to a medical condition, the wig could be categorized as a medical tax deduction.

11. Sales and income taxes

Many filers forget to include state sales and income taxes paid as deductions. If you live in a state that doesn't impose an income tax, tallying up all the tax you've paid on personal and household items can really add up to savings. On the other hand, if your state does have an income tax, it's usually a better strategy to claim that as a deduction on your tax forms, unless you made some big-ticket purchases, such as a car or boat.

12. Student loan interest

Parents with dependents who have student loan debt can deduct the interest they paid on their child's loans throughout the year. Alternatively, if you are paying off your own student debt, you should receive form 1098-E from your student loan lender showing how much interest you paid, so you can deduct the qualifying amount on your tax return.

Unfortunately, you can only deduct up to $2,500 of interest each year. And, if your college education paid off in the form of a job with significant income, your deduction might be limited or even eliminated.

13. College tuition and training costs

Still in school or taking classes to get a graduate degree or improve your job skills? You might be able to deduct some of your expenses by claiming another useful tax credit -- the Lifetime Learning Credit, which allows you up to $2,000 in the form of a tax credit if your income doesn't exceed certain limits ($66,000 for single filers and $132,000 for a married filing jointly return in 2018). To claim the credit, you will need to file form 8863.

14. Energy-saving home improvements

Making your home more energy-efficient can help you score a tax credit known as the Residential Energy Efficient Property Credit. Currently, you can get a 30 percent credit for qualified solar electric systems and qualified solar water heaters. Along with saving money on your tax bill, you can do your part to help the environment by taking advantage.

15. Mortgage points and remodeling costs

Although most people know about the biggest tax deduction for homeowners -- mortgage interest -- other deductions do exist. When itemizing, taxpayers who made improvements to their current homes can deduct state sales tax for building materials.

Also, individuals or couples who bought a house during the tax year should be sure to claim the interest paid on their mortgage points, and homeowners who paid points when they refinanced their mortgages might also be able to deduct them.

16. Military Reserve travel costs

For members of the National Guard or military reservists, you can deduct partial travel expenses for attending meetings or drills more than 100 miles from home, even if you don't itemize. You can treat all of your lodging costs and half your meal expenses as tax write-offs.
