When I inpu the number for my expenses against my self employment income, do I input the total for the year or do I pre-calculate an amount based on my business use?

Say only 15% of my income comes from self employed. Do I only use 15% of my total expenses for the year of auto, restaurants, home expenses etc. or do I put the total number spent in a year and it will only take the max I can claim?

What you enter for your expenses doesn't go based on your income, it goes by what percentage of the expense was for your self-employment. Ex: if you had a printer that you used 90% for your self-employment, then you can claim 90% percent of the cost of ink.

How you enter the amounts depends on what the expense is. For the printer ink, you would just put in 90% of the total cost. For motor vehicle costs, you would put in the total you spend for gas, maintenance, etc... and the software will pro-rate the amount based on the kilometres you used for your self-employment work.
