The first 30 days: six decisions that are expensive to reverse
Six administrative choices made in a freelancer's first month that cost real money to undo: structure, VAT, banking, contracts, terms and records.
Advice about a freelancer's first month is almost always a list of skills. Skills are the reversible part: you can negotiate badly in March and well in June, at no cost beyond the difference between the two prices.
The decisions you make in that same month about legal structure, tax registration, banking, contracts, payment terms and records do not behave that way. Some have a fixed price to undo: changing your UK structure later means £100 to incorporate online and £50 a year for the confirmation statement, the cheapest item here. Some have a deadline, after which the answer is "next year." Two have no reversal price at all, because they change a level rather than a setting: your working capital, and the quality of the record you can produce about a year already gone.
This covers the US, UK and EU positions, which diverge sharply on two of the six, and not finding your first client, which is a different problem with a different clock.
The structure question is really two questions, and only one has a deadline
In the US you are a sole proprietor by default, with nothing to file. An LLC is a state-level registration that changes liability without changing tax: the IRS treats a single-member LLC as a disregarded entity, you still file Schedule C, and the owner remains "subject to the tax on net earnings from self employment in the same manner as a sole proprietorship." One burden people still budget for has gone: FinCEN's interim final rule of 26 March 2025 exempts all entities created in the United States from beneficial ownership information reporting.
The tax decision is separate and it is the one with a clock on it. Electing S corporation treatment is done on Form 2553, which the instructions require "no more than 2 months and 15 days after the beginning of the tax year the election is to take effect." Miss that window and the earliest it can bite is the following year. The reversal cost is not a fee, it is twelve months.
In the UK, sole trader is the default and you register with HMRC by the 5 October following the end of the tax year in which you started. A limited company costs £100 to incorporate online and is usually registered within 24 hours, then carries the £50 confirmation statement every year plus statutory accounts. Going back is not a form; it is a strike-off and, depending on what the company holds, a distribution. Across the EU there is no single answer worth giving, because registration cost, minimum social contributions and accounting duties differ by Member State; the rule that does operate EU-wide is the next decision.
Registering for VAT before you have to is a pricing decision
The UK threshold is £90,000 of taxable turnover on a rolling twelve months, plus a forward test if you expect to exceed £90,000 within the next 30 days. Below it, registration is voluntary, and the question is who pays for it.
If your clients are VAT-registered businesses, the VAT you add is neutral to them and you reclaim input VAT on your own costs, so registering early is a small net gain. If they are consumers, or VAT-exempt buyers such as much of healthcare, education and financial services, the VAT is a real 20% price rise that either they absorb or you do. Absorbing it on £40,000 of turnover costs you £40,000 − (£40,000 ÷ 1.2) = £6,667 of net income a year. The decision turns on client mix, not tidiness.
The Flat Rate Scheme is where the received wisdom is worst. It is open at VAT turnover of £150,000 or less and gets recommended as free money. Check it against the limited cost business rule: if your spending on goods is under 2% of turnover, or under £1,000 a year, your flat rate is 16.5%. On £40,000 of net fees you charge £8,000 of VAT, making £48,000 gross, and pay HMRC £48,000 × 0.165 = £7,920. You keep £80, and you have given up reclaiming input VAT on software, hardware and your accountant. The 1% first-year discount takes the rate to 15.5% and the retained amount to £560, for one year.
The EU position changed on 1 January 2025 and deserves more than its usual footnote. Under Council Directive (EU) 2020/285, the small business exemption stopped being limited to the country you are established in, so a freelancer established in one Member State can sell VAT-exempt into others without registering there. Two ceilings apply: each Member State's own national threshold, which it may set anywhere up to a cap of €85,000, and a €100,000 Union-wide ceiling across all 27 in both the current and previous calendar year. You notify once at home, receive a single "EX" identification number which "should not take longer than 35 working days," then file one quarterly report to your own tax authority covering turnover in all 27. National thresholds are not uniform, so read the country table rather than assuming €85,000 everywhere, and note that breaching the €100,000 ceiling excludes you in every Member State at once, deactivating the EX number until a quarantine period passes.
The bank account is the decision with the shortest argument
IRS Publication 583 puts it about as plainly as tax guidance gets: "One of the first things you should do when you start a business is open a business checking account."
The cost of ignoring it is not a penalty, it is reconstruction: twelve months of statements sorted from memory, when you are already late for something else. An expense you cannot evidence is not a deduction, and if you formed a company for liability separation, commingling erodes the thing you paid for. Bank feeds and receipt matching are only as useful as the account is clean.
The contract you pick in month one is the one you will send in year three
Nobody rewrites a contract that has not failed yet. The template you settle on now gets reused until a project goes wrong, so the question is not whether it suits this client but which missing clause you regret on the tenth.
Four clauses are cheap now and awkward to retrofit. A scope boundary with a stated procedure for changes, so a change is a re-quote rather than a favor. A payment position that does not waive your statutory late-payment entitlements, which under Directive 2011/7/EU and the Late Payment of Commercial Debts (Interest) Act 1998 apply automatically unless your contract says otherwise. A right to suspend work when an invoice passes a stated age. And IP transferring on payment rather than delivery, the clause that most changes your position when a client goes quiet.
Retrofitting these is cheap in legal fees and expensive in signaling: asking twelve existing clients to sign revised terms reads as a change of stance. The contract generator produces a signable PDF in the browser with no signup or watermark, and Worklyn's contracts feature adds e-signature and a clause reader that flags what is missing.
Your default payment terms are a working capital choice you make once
Whatever you type on the first invoice becomes your default, and the default becomes the precedent clients compare against when you try to change it.
Do the arithmetic before picking a number. Moving from 30-day to 45-day terms on €60,000 of annual billing permanently parks €60,000 × (15 ÷ 365) = €2,466 in receivables. That is not a one-off delay, it is a level shift that stays until your terms change, and at €2,700 of monthly fixed costs you have given away most of a month of runway.
Jurisdiction sets the baseline. In the EU, Directive 2011/7/EU makes 30 calendar days from receipt of the invoice the default B2B period and caps terms at 60 days unless expressly agreed and not grossly unfair to you. The UK has no statutory cap; the Commercial Payments Bill introduced in May 2026 would cap B2B terms at 60 days if it passes, but it is not law. The US has no general B2B default at all, so your contract is the only thing setting the term. Note what the EU clock runs from: receipt of the invoice, not completion of the work, which makes invoicing speed part of your terms. The guide to getting paid on time covers deposit structure and invoice timing.
The record you start in month one is the only record of month one
Two US changes make this urgent. The 1099-NEC and 1099-MISC threshold rose from $600 to $2,000 for payments made after 31 December 2025 under Pub. L. 119-21 §70433, and the 1099-K threshold reverted to more than $20,000 and more than 200 transactions, both of which must be met. Neither changes what income is taxable. They change how much of your income arrives with no form attached, which for a freelancer with several small clients is most of it. Your record is the record.
The IRS does not dictate format. Publication 583 says "the law does not require any specific kind of records," with retention generally three years from filing. So the decision is not which software, it is whether the record is a by-product of doing the work or a reconstruction from statements.
The UK removes the choice on a timetable. Making Tax Digital for Income Tax went live on 6 April 2026 for anyone whose qualifying income exceeded £50,000, dropping to £30,000 from April 2027 and £20,000 from April 2028. Qualifying income is gross self-employment and property income before expenses, so it catches people whose profit is far below the threshold. It requires compatible software and cumulative quarterly updates due 7 August, 7 November, 7 February and 7 May. A spreadsheet does not satisfy it.
Weighing a full accounting package against something narrower is a question of where your day happens: a QuickBooks alternative built for freelancers sets out the trade-off between a ledger a bookkeeper likes and a workspace where invoices, hours and receipts land together. In the UK the same question usually arrives as FreeAgent, and the comparison for the work around the accounting is the version of it that assumes MTD filing is already handled elsewhere. Why tax season is a year-round system covers the MTD and US quarterly deadlines, and the tax set-aside calculator gives you a monthly reserve figure.
What each of these costs to undo
Decision | If you don't choose | Cost of changing it later | When to revisit |
|---|---|---|---|
Legal structure | US sole proprietor, UK sole trader | US: missing the Form 2553 window pushes an S election a year. UK: £100 to incorporate, £50 a year after | When procurement requires a company, or profit justifies the election |
VAT registration | Not registered, right for most in month one | Deregistration is available below £88,000, but prices raised 20% for consumers don't come back down quietly | UK: monthly as turnover approaches. EU: before the first cross-border B2C sale |
Business banking | Everything through your personal account | A year of statements re-sorted from memory | Now. Nothing argues the other way |
Contract template | You sign whatever the client sends | Asking every existing client to re-sign; some will renegotiate | Before the second client, not the tenth |
Payment terms | Whatever you typed on invoice one | A permanent step change in receivables: €2,466 per 15 days on €60,000 of billing | At renewal, never mid-project |
Income record | Bank statements plus recollection | Rebuilding a year retrospectively, under deadline | UK: before qualifying income passes £50,000. US: now |
The order to make them in
Two of the six are worth doing this week whatever your size, because they cost nothing now and only get more expensive: the separate account and the record system. Two more should be settled before the second client, because both get harder in proportion to the number of relationships you would have to renegotiate: the contract template and the default payment terms. Structure waits for a forcing event, and there are only two: procurement that will not contract with an individual, or profit high enough that the S election beats the cost of running a corporation.
VAT is the one with a real threshold, and the rule is not the statutory number. Monitor at £90,000 minus your largest single invoice, because the UK test is a rolling twelve months plus a 30-day forward look, and one large project in the wrong month can carry you over before your next review. If your biggest invoice is £12,000, your alert sits at £78,000, not £90,000. In the EU the €100,000 Union ceiling matters more than the national one, since breaching it removes the exemption in all 27 Member States at once.
All six sit inside a longer sequence, laid out in the guide to going freelance organised by money milestones. If you have not left employment yet, the three financial tests to run before you hand in notice come first, and Worklyn for freelancers is where these decisions end up living.
The last one compounds fastest. Worklyn builds that record as a by-product of sending the invoice, with receipt matching behind it, which is the only bookkeeping most freelancers sustain past March.
