It is important to know that while seeking the help of professionals is advisable, you always want to make sure to do your own research and check for deductions on your own. Make sure that if there is any ambiguity in an IRS regulation that you check with a tax professional or with the IRS before you take a questionable deduction. No matter how great the deduction may be it is not worth getting audited over.

A great place to start is at IRS.gov where there are several publications written in a readable style to help you learn what expenses are considered tax deductible for the self employed. Form 1518, IRS Tax Calendar for Small Businesses and Self-Employed and form 535, Business Expenses, are two excellent informative publications to help you get started learning about deductions.

Making sure you follow the IRS instructions is very important and you need to be aware there are several keys that can lead to your getting audited. Claiming your house as a deduction is the number one alert to the IRS that can lead to an audit. That is not to say that you cannot deduct the correct portion of your house, just make sure that you do it within the guidelines of what the IRS allows.

Travel is another area you want to be very careful about when deducting as a business expense. The IRS has very specific guidelines regarding what is considered business travel and what traveling expenses are eligible for deductions according to the regulations.

Supplies and equipment for your business are deductible and health insurance also may be deducted. If only one member of your family is self employed be aware that you may only be eligible to deduct the self-employed family member’s healthcare costs. If the other family member is eligible for benefits through their employer then you cannot claim the cost of those benefits as a deduction.

Clothing can be deductible but only if it is usable for the business purpose exclusively. If you have a coat that can be worn when you aren’t working then it would not be considered deductible. If however, it is something like a specific fire proof jacket is needed and it isn’t possible or pragmatic to wear it when you aren’t working then that fireproof jacket would be considered tax deductible.

Studying the forms and guides provided by the IRS is a great place to start but also include a visit to your CPA who can take what you have learned and apply their knowledge and experience to maximize your deductions for the upcoming year’s tax liability you face as a self-employed business person.

You won’t find any difference between traditional and home-based businesses when it comes to paying taxes. The income tax remains based on, not how your business operates, but on the type of business you have. Thus, your home-based business is allowed to claim business expenses relevant to your operations, including the Home-Based Business Tax Deduction, if you operate your business from your own home. But there are rules to follow regarding tax write offs for the online business. There’s no considerable return if you are unaware of the tax write offs for the online business.

For instance, regarding the home office issue, operating a business from your home entitles you to take some significant tax deductions if you meet certain IRS conditions. These conditions include: your home office must be used "exclusively" and "regularly" for business use. This renders the space to be primarily for business purposes and is not used for family or personal activities, unless you want to start dividing up the time. Secondly, the business activities that are conducted in your home office can’t be conducted from anywhere else. A rented office space thus spoils the tax deduction. Therefore, if you rent a specific space as a home office, you will be unable to claim the Home-Based Business Tax. If you qualify for the Home-Based Business Tax, the amount of the tax deduction will be dependent upon your costs, i.e. property taxes, insurance costs, utility bills, mortgage and rent payments and the property maintenance cost.

Home-based businesses also have the opportunity to claim any and all relevant supplies purchased throughout the year. Claiming office products such as computers, papers, pens and even the Internet connection, are relevant to not only physical businesses but virtual businesses as well. The conditions regarding these deductions pertain to usage. If a computer is housed in a home with a 12 year old and it is the only computer in the home, the IRS will believe that 12 year old a user of the computer. Thus, you will not be able to claim the entire cost as a tax deduction. There are pro-rated deductions based upon time of usage for these circumstances.

Keeping track of receipts and bills is often the most missed tax deduction. Home-based businesses rarely understand that everything in the home that pertains to their business can be deducted in some way, shape or form. Home-based businesses can even claim the money they pay the children in the home when they help out with the business.

Home-based businesses are flourishing all over the United States. Many people now, never have to leave the comfort of their homes to earn a successful income from a business venture. These businesses often forget that fact that they truly are a business and therefore can deduct the same tax write-offs as any other physical business.

Unpaid invoices - You can claim any non-payment from customers as a loss on your taxes. If you have unpaid invoices from years past, don’t worry, you don’t have to take the deduction the year it occurred. So gather up your old paperwork and go ahead and deduct them on this year’s return.

Mileage - You may have heard about this deduction, but are you keeping track? All those short trips to the bank, post office, restaurants and airport add up big time over the course of 365 days. If you start doing it, you will be amazed at how much money you’ll be able to write off. At a 32-cent deduction per mile, these add up very quickly and at the end of the year, it is a real eye-opener to see how much you’re able to write off. Oh, don’t forget tolls either!

Shipping and postage expenses - This is another often-overlooked deduction. Once you see how much everything adds up to, you’ll gladly take that deduction every year!

Your home - If your house is also your place of business you have the right to depreciate a percentage of the home’s total square footage depending on the percentage of your home that is used exclusively for your business.

Utilities - Do you have electricity, gas, phone, etc.? Up to a third of these can be deductible.

Cell phone / PDA bills - If you are using your cell phone/PDA for keeping in contact with business associates, then the cost off your phone and your monthly bills are a deduction.

Business Meals - Any time that you go out for meals or drinks and discuss business with someone (even your spouse) then you can deduct that meal as a business expense. Be sure to deduct the miles it took to drive there and back too!

Travel Expenses - Any time to you travel with the purpose of maintaining or expanding your business (i.e. trade shows, client visits, etc.), the expenses associated with that are deductible. That means hotels, airfare, meals, rental car, etc.

Of course, in all the above cases, you must keep complete records if you are to qualify for the tax deductions. That means receipts or detailed entries (depending on the deduction). Generally, all expenses incurred while maintaining or expanding your business are deemed as tax deductible.
