I am self employed. My country allows me to declare flat expenses on up to 60% of my income. No accounting or proof needed. Real taxation is around 20% on $100K income (including social and health insurance). So every year I spend about 2 hours with: - sum all money that arrived to my account in last year - fill form on IRS website - update standing orders for health/social contributions for the next year - one month latter, ring IRS and other offices, just to check all went through If you move every two months, I would not worry about it too much. Important is: - you pay taxes somewhere (preferably in your home country) - you do not work for locals
