Employees have taxes withheld invisibly. When you work for yourself, nobody withholds anything — which means tax is a cash-flow discipline, not a once-a-year event. This checklist turns it into a repeatable 90-day rhythm.

Every time you get paid

• Move your set-aside percentage — {{Your set-aside, e.g. 25–35%}} — to a separate account you never spend from. Same day the payment lands, before it feels like yours.
• Record the invoice, the payment date, and the client in your ledger. Thirty seconds now saves an evening in April.

Month 1 of the quarter

• Reconcile last quarter: does your ledger match your bank account and your invoices? Chase any client whose payments don't line up.
• File and pay any estimated obligation that falls due in your jurisdiction, from the set-aside account.
• Check whether your set-aside percentage still matches reality — if income jumped, raise it.

Month 2

• Sweep expenses: pull receipts from email, card statements, and apps into your records while you still remember what they were.
• Tag anything ambiguous now with a one-line note ("co-working day pass — client workshop"). Future-you will not remember.

Month 3

• Preview the year: multiply the quarter's average by remaining quarters. Are you drifting into a higher bracket or threshold that changes your obligations (registration, indirect taxes, entity choice)? Flag it for your advisor.
• Review subscriptions and tools — cancel what you stopped using; those are both money and clutter in your expense records.

Once a year, with a professional

• Have a qualified local advisor review your set-aside rate, entity structure, and any cross-border complexities.
• Ask specifically: "What changed in the rules this year that affects someone like me?" — the answer is rarely nothing.

The one rule that matters most

The set-aside account is not an emergency fund, not a float, and not available for a slow month. Money that is mentally spent twice is the root of nearly every freelancer tax crisis.
