Irregular-Income Worked Example
Suppose three freelance months bring in $4,000, $8,000, and $6,000. That is $18,000 across the quarter, or a $6,000 monthly average. For one planning example, a 25% manual tax reserve would set aside $1,500; $900 of business costs, $2,600 of personal costs, and $500 of savings would leave $500 before any other budget items. A lower-income scenario can also be tested to see how the plan holds up when work slows.
The 25% reserve in this example is an illustration, not a recommended tax rate or tax advice.
