If you have had transport costs in connection with your b-income job, you can deduct them from your b-income. There are different rates depending on whether you drive a car, motorcycle, EU moped, moped or bicycle - yes, there is even a deduction rate for driving to / from work by bike. These rates vary depending on how far you drive in total. But you do not have to worry about all that - at b-indkomst.dk you just have to enter your from and to address, and the system does the rest. If you have costs for planes, buses, trains, taxis or other, b-indkomst.dk of course also handles it. You must be able to document your deductions with SKAT.

In addition to driving, you as a b-income recipient may have other costs that are directly related to your b-income. You can also deduct these costs. It is impossible to make a complete list of deductible expenses, and what they may be, of course, also depends entirely on what activity your b-income originates from. Here are some examples:

• Musician: Blades for your saxophone, mouthpiece for your trumpet, muffler for your trumpet, rental of rehearsal room, rental of equipment, etc.

• Doctor: Medical bag, stethoscope, etc. 

• Lecturer: Computer (however, SKAT may think that only about 10% of the value of the computer is deductible, as it can also be used privately. This is a matter of discretion that can be discussed with SKAT. This of course applies in general to computers and not only to speakers.) 

• Author: Computer (see above), courses, other materials, etc. 

• Journalist: Paper, writing utensils, dictaphone, courses, special software, etc. 

• Actor: Equipment, courses, make-up, etc. 

• Sports teacher: Equipment, courses, etc.

​

There is an upper limit to how much a single item must cost for it to be deducted for one year (this is also called immediate-depreciation). For 2011, this limit is DKK 12,300, but the amount varies from year to year. If you buy something that is more expensive than this limit set by SKAT, it is called an investment. But you do not have to worry about all this if you use b-indkomst.dk. Then it is impossible for you to make mistakes.

If you do not expect your B-income for the year to amount to more than, for example, DKK 50,000, then b-indkomst.dk recommends that you do the following:

​

1. Adjust your advance statement so that you state that you do not expect to have any B-income. You do this by writing 0 in box 210 "Fees and salaries for civilian conscripts" in your advance statement. Then you avoid having to pay on account payments to SKAT, but you must then in turn be aware that the tax must be paid later.

• If you have already paid on account B-tax (or made voluntary payment of tax) to SKAT for one / several months, you must state in advance the total amount you have already paid in box 342.

• If you have already paid in one or more on-account B-tax rates, remember to also enter the sum of these amounts on b-indkomst.dk on the tab "Overview" for the year in question. Then b-indkomst.dk includes this in the calculation of your expected tax payment.

2. REMEMBER to write all your B-income jobs on b-indkomst.dk regularly . Also remember to state your deductions and investments. If you do this on an ongoing basis , you can always see on the tab "Overview" what you should set aside for payment of AM contributions and taxes. (Possibly deducted from the payments you may have already made via payment card.)

3. As SKAT attributes day-to-day interest to any residual tax from 1 January (in the year following the income year), it is most advantageous if you remember to pay your tax due BEFORE 1 January. But don't worry - you will receive an email from b-indkomst.dk when it is time to pay voluntarily to SKAT. This way you avoid having to pay annoying interest - and you also do not have to keep in mind when exactly you have to pay voluntarily to SKAT.

If you expect your B-income for the year to amount to more than, for example, DKK 50,000, then b-indkomst.dk recommends that you do the following:

1. Estimate your expected B-income conservatively (at the bottom) and state this in your advance statement. You do this by entering the amount in box 210 "Fees and salaries for civilian conscripts" in your advance statement.

2. REMEMBER to update the amount for your total payments of AM contributions and B-tax on b-indkomst.dk on the tab "Overview" for the year in question, each time you make a payment. Then b-indkomst.dk includes this in the calculation of your expected tax payment.

3. REMEMBER to enter all your B-income jobs on b-indkomst.dk. Also remember to state your deductions and investments. If you do this on an ongoing basis , you can always see on the tab "Overview" what you should possibly set aside for additional payment of AM contributions and B-tax - or whether you may have paid too much in AM contributions and B-tax . b-indkomst.dk automatically deducts the payments you have already made via payment cards and possibly other voluntary B-tax payments, as long as you remember to state these, cf. 2.

4. If you can see that you owe money to SKAT and the amount is significant, then you should deposit this amount as a voluntary payment. This can be done very simply via SKAT's website using Dankort. Keep in mind that deductions or a large investment can affect your tax due, so if you know you can look forward to this, you may have to wait to pay voluntarily. If you make a voluntary payment of B-tax, then it is important that you remember to correct the amount for your total payments of AM contributions and B-tax on b-indkomst.dk on the tab "Overview".
