2019 Schedule 1  Additional Income & Adjustments to Income


If you get tax subsidies through Covered CA to pay your premium,
the deduction claimed for the premiums under §106  * line 16  and the Premium Tax Credit (PTC)

that gets  computed,
taking the deduction into account, must be less than or equal to the premiums

Now that’s a mouth full isn’t it!

Check out  Publication 974 where there are special instructions for figuring the self-employed health insurance deduction and PTC if you or your spouse was self-employed, you or a member of your tax family was enrolled in a qualified health plan and you may be eligible for the PTC.

Because the amount of the self-employed health insurance deduction may affect the amount of the PTC, and the amount of the PTC may affect the amount of the deduction, a taxpayer who may be eligible for both may have difficulty determining the amounts of those items.

A taxpayer who may be eligible for both may follow the instructions in this part to determine amounts of the self-employed health insurance deduction and PTC that are allowable under the law.  Publication 974

IRS Tax Tips for Self Employed

If you are self-employed, you normally carry on a trade or business. Sole proprietors and independent contractors are two types of self-employment. If this applies to you, there are a few basic things you should know about how your income affects your federal tax return. Here are six important tips from the IRS:

  • SE Income. Self-employment can include income you received for part-time work. This is in addition to income from your regular job.
  • Schedule C or C-EZ. You must file a Schedule C, Profit or Loss from Business, or Schedule C-EZ, Net Profit from Business, with your Form 1040. You may use Schedule C-EZ if you had expenses less than $5,000 and meet certain other conditions. See the form instructions to find out if you can use the form.
  • SE Tax. You may have to pay self-employment tax as well as income tax if you made a profit. Self-employment tax includes Social Security and Medicare taxes. Use Schedule SE, Self-Employment Tax, to figure the tax. If you owe this tax, attach the schedule to your federal tax return.
  • Estimated Tax. You may need to make estimated tax payments. Try IRS Direct Pay. People typically make these payments on income that is not subject to withholding. You usually pay estimated taxes in four annual installments. If you do not pay enough tax throughout the year, you may owe a penalty.
  • Allowable Deductions. You can deduct expenses you paid to run your business that are both ordinary and necessary. An ordinary expense is one that is common and accepted in your industry. A necessary expense is one that is helpful and proper for your trade or business.
  • When to Deduct. In most cases, you can deduct expenses in the same year you paid, or incurred them. However, you must ‘capitalize’ some costs. This means you can deduct part of the cost over a number of years.

How much subsidy to take?


Max Herr  —


When I work with a client who is self-employed and whose income is irregular/inconsistent from month-to-month, if he/she is eligible for any amount of premium tax credits, I first urge them to not take them in advance at all, if the premium for their chosen health plan is within their means to begin with.

If, however, they need the help from Uncle Sam to pay premiums, then I recommend that they accept no more than 50% – 75% of what CoveredCA estimates their monthly tax credits to be. By doing this, it gives breathing room to earn more money, and lessens the risk of having to repay any credits, or minimizes the amount of credits to be repaid.

If their income ends up as projected or less, then they will receive the balance of unused tax credits as a refund (or applied to any unpaid tax owed).

  1. My wife and I have had some serious work challenges over the last year and our income has plummeted down ridiculously low but we’re still on a private-pay Kaiser plan.

    We just had our fourth child and the monthly premiums at Kaiser are getting a bit out of hand for us.

    Do we qualify for Covered California and at what level.

    We’re both self-employed at the moment so I’m not sure what kind of proof of income you need
