Medical billing service taxes and deductions

Handling protected health information for other practices makes you a business associate in your own right. Secure systems, signed agreements, encrypted storage and breach cover are legal requirements and ordinary deductible costs at the same time.

Cyber liability cover is the deduction most billing services do not carry until a client asks for proof of it. Clearinghouse fees and practice management software are ordinary subscriptions. Payment on a percentage of collections means income moves with the client's revenue, so estimates based on last year's bill are safer than a forecast.

The deductions with a rule attached

These are the lines where the answer is not simply "keep the receipt"each has a cap, a percentage or a test that decides how much of the spend you actually get:

Home office: Two methods. Simplified is $5 a square foot to a ceiling of 300 feet, $1,500, no records beyond the measurement, and no depreciation recapture when you sell the house. Actual apportions your rent or mortgage interest, utilities, insurance and repairs by floor area, usually gives more, and does bring recapture. Either way: space must be used regularly and exclusively for business. home office must be principal place of business.
Phone: You get the business-use percentage of the bill, not the bill. Business-use percentage of total cost. A line you also use personally is a split, and the split needs to be defensible rather than round.
Internet, at the business-use percentage: You get the business-use percentage of the bill, not the bill. Business-use percentage of total cost. A line you also use personally is a split, and the split needs to be defensible rather than round.

The rest of the medical billing service deduction list

Ordinary and necessary business expenses, deductible in full in the year you pay them, provided they are genuinely for the business:

Practice management software
Staff wages
Errors and omissions insurance
Cyber liability insurance
Compliance costs

Worth knowing

You handle protected health information for other people's patients, which brings security obligations that are both mandatory and deductible.

That is what is specific to this trade. The larger deductions are the universal ones, see the full checklist.

What each deduction is worth to you

On $100,000 of profit with no state income tax, $1,000 deducted saves $305, 30.5%, because it comes off self-employment tax and income tax together:

Net profit	Saved per $1,000 deducted	Effective
$40,000	$231	23.1%
$100,000	$305	30.5%
$200,000	$297	29.7%

The last row is worth less than the one above it, and that is not a mistake: past the Social Security wage base the self-employment part of the saving drops from 15.3% to 2.9%, and the higher income-tax bracket does not quite make up the difference. A deduction is worth most in the middle.

Add a state income tax and every row rises. The 1099 calculator applies that layer.

Where this comes from

The rules on this page that are specific rather than general are cited below. Follow a link to read the provision itself rather than taking our word for it:

Health excludes services not directly related to a medical field, naming payment processingReg. 1.199A-5(b)(2)(ii)medium confidence

What these words mean

Depreciation: Spreading the cost of something long-lasting, a vehicle, a camera, a tractor, across the years you use it, rather than deducting it all at once.
Depreciation recapture: When you sell something you had been depreciating, the tax office takes back part of the benefit by taxing the gain up to the amount you already deducted.

General information about how these deductions work, not tax advice. Whether a particular expense is deductible for you depends on facts this page does not have, check with a tax professional before claiming anything listed here.
