The Profit First Method for Trade Businesses — A Simple Way to Always Have Cash (2026)

Why Bank-Balance Accounting Fails Tradespeople

The problem with running your business off the bank balance is that the money sitting in the account isn't all yours. A chunk of it belongs to HMRC — the VAT you've collected on top of your invoices, and the income tax and National Insurance you'll owe on your profit. Another chunk is owed to suppliers for materials you've bought on account. And a portion should belong to your future self, as profit and savings.

When you spend to the balance, you spend all of that — the taxman's share, the supplier's share and your buffer included. This is how busy trades end up skint. You can have a great year on paper, turn over plenty of work, and still be scrambling to find the tax money because every pound that came in got spent on diesel, materials, the van, the kids and a holiday. A single account tells you what you have today. It tells you nothing about what is already committed to someone else.

The Core Idea — Flip the Formula

Traditional accounting works like this: Income − Expenses = Profit. Profit is whatever happens to be left over at the end, and for most small trades that turns out to be very little, because spending expands to fill whatever's in the account.

Profit First flips it: Income − Profit (and tax) = what's left to spend. You take your profit and your tax money off the top the moment cash arrives, move it somewhere you can't easily touch it, and then run the whole business on what remains. It sounds almost too simple, but the discipline it forces is the entire point. If the tax money is gone before you see it, you can't accidentally spend it. If the business has to survive on what's left after profit and tax are removed, you find a way to make it work — exactly the way you'd trim your household spending if your wages dropped.

The Accounts — Your Pots

The mechanism is straightforward: set up several separate bank accounts (or savings pots / "jars" if your bank offers them), and split every payment that comes in by percentage. Everything lands in one place first, then gets divided up. A typical set of pots for a trade looks like this:

• Income: the account every customer payment lands in. Nothing is spent from here — it's just the holding pen before you allocate.
• Tax: for income tax and National Insurance on your profit. This money is HMRC's — treat it that way.
• VAT: if you're VAT registered, keep the VAT you collect completely separate. It was never your money — you're just holding it for HMRC until the return is due.
• Profit: a real profit and savings buffer. This builds up over time and is the cushion that gets you through quiet months.
• Owner's Pay: your wage. You pay yourself a consistent amount from here rather than dipping into the business whenever you fancy.
• Operating Expenses: materials, fuel, tools, insurance, software, accountant — the day-to-day cost of running the business.

The single most important rule is to keep the Tax and VAT pots ring-fenced. Once that money is moved out of reach, you stop seeing it as available, and the January tax bill or the quarterly VAT return stops being a crisis. Many tradespeople find that just doing this one thing — separating the VAT and tax — transforms how the business feels, even before they bother with the profit and owner's pay pots.

How to Pick the Percentages

Don't start from some ideal you read online — start from where you actually are. Pull your last year's numbers (your accountant or your bookkeeping software will have these): what did you turn over, what did materials and running costs actually come to, what was your tax bill, and what did you take out for yourself? Work backwards from that to set percentages you can realistically hit today, then nudge them in the right direction over the coming months.

As an illustrative example only — this is not financial advice and your figures will be different — a trade business with modest material costs might start with something like:

• Tax: 20% (income tax and NIC — your actual rate depends on your profit)
• VAT: kept separate at whatever rate you collect (typically 20%, or less under a flat rate scheme)
• Owner's Pay: 50%
• Operating Expenses: 25%
• Profit: 5%

These numbers vary massively from one business to the next. A materials-heavy trade — a kitchen fitter, a roofer buying tiles and scaffold, a builder turning over large material orders — will need far more in the Operating Expenses pot and proportionally less as owner's pay. A labour-only trade with low overheads can pay themselves much more. The exact split matters far less than the fact that you're doing the split at all. The method is what fixes the problem, not the precise percentages.

Build a Rhythm

Profit First works because it becomes a habit, not a one-off. Pick a set schedule for your allocations — twice a month (say the 10th and the 25th) is common — and stick to it. On allocation day, look at what's landed in the Income account since last time, and transfer the set percentages out into each pot. Then you pay yourself from Owner's Pay, settle supplier and running costs from Operating Expenses, and leave the Tax and VAT pots untouched until those bills are due.

Let the Profit pot quietly build. It becomes your buffer for the inevitable quiet spell — the January lull, the rained-off fortnight, the month a big client pays late. A growing profit pot is also what lets you eventually take a proper profit distribution a couple of times a year as a reward for running a healthy business. Think of it as the foundation of a proper cash reserve — the few months of running costs that mean a slow patch is an inconvenience rather than an emergency.

Why This Suits Trades Specifically

Trade income is lumpy. You might invoice nothing for two weeks while you're mid-job, then get three payments in the same week. You have big material outlays up front before the customer has paid a penny. Many trades have seasonal quiet spells — outdoor work in deep winter, for instance. And the tax and VAT bills, when they land, are large and scary precisely because they're infrequent. Every one of these is exactly what the Profit First approach smooths out.

• You always have the tax and VAT money, because it was moved aside the day the payment came in.
• You pay yourself a consistent wage instead of feast-and-famine drawings that wreck your household budget.
• You build a buffer that carries you through the lean weeks without reaching for an overdraft or a credit card.

Getting Started

You don't need anything fancy to begin. Most UK business banks and fintechs — the likes of Starling, Tide, Mettle, Monzo Business and the high-street banks — let you open multiple accounts or create savings "spaces" or "pots" within one account at no extra cost. That's all the infrastructure you need.

• Open the extra accounts or pots — at minimum, get a separate Tax pot and (if registered) a VAT pot in place first.
• Work out your starting percentages from last year's real numbers.
• Automate the transfers where you can, or block out a recurring diary slot for allocation day so it actually happens.
• Review the percentages quarterly and adjust as the business changes.

One important caveat: this system complements proper bookkeeping and a good accountant — it does not replace them. Profit First is about cash behaviour, not about working out your exact tax liability or filing your returns. Keep your records straight and let your accountant tell you the real numbers; use the pots to make sure the money is there when those numbers come due.

Common Mistakes

• Dipping into the Tax or VAT pot "just this once." The moment you borrow from these to cover a cash gap, the system is broken — because you'll do it again, and the bill still has to be paid. That money is not yours to use. Ever.
• Setting unrealistic percentages and giving up. If you decide to pay yourself a fortune and starve the expenses pot, the system collapses within a month and you blame the method. Start from reality and improve gradually.
• Not actually separating the money. A pot in your head — "I know roughly how much is the taxman's" — does not work. The whole point is that the money is physically somewhere you can't casually spend it. If it's all still in one account, you're not doing Profit First.
• Treating it as a software problem. No app fixes this for you. It's about behaviour: the discipline of allocating on schedule and leaving the ring-fenced pots alone. The tools just make the transfers easier.

A materials-heavy trade would shift more into Operating Expenses and less into Owner's Pay; a labour-only trade can do the reverse. Adjust to fit your real numbers.

Frequently Asked Questions

What is the Profit First method?

Profit First is a cash-management system, popularised by Mike Michalowicz, that reverses the usual accounting formula. Instead of Income − Expenses = Profit, you take your profit and tax off the top first — Income − Profit (and tax) = what's left to spend — by splitting every payment into separate accounts the moment it arrives. Because the tax, VAT and profit money is moved out of reach before you can spend it, you always have it when the bills come due.

How much should I put aside for tax as a tradesperson?

It depends on your profit and your tax band, so this is general guidance rather than advice — confirm with your accountant. As a rough starting point, many sole traders set aside somewhere around 20–30% of their profit for income tax and National Insurance, with higher earners needing more. If you're VAT registered, keep the VAT you collect completely separate on top of that. The safest approach is to set a realistic percentage, ring-fence it the day the money comes in, and let your accountant confirm the exact figure each year.

Do I need separate bank accounts for my trade business?

You don't strictly need separate bank accounts — many UK business banks let you create multiple savings pots or "spaces" inside a single account, which works just as well. The crucial part is that the money is physically separated, not just mentally earmarked. At a minimum, have a dedicated Tax pot and, if you're registered, a VAT pot, so that money is never sitting in your main spending account tempting you to use it.
