• Pension contributions.
• Capital gains.
• Other taxable income.
• Personal Allowance.
• National Insurance contributions.

• Payments on account.

However, there are sensible guidelines that work for most people.

How Much Should You Save?

Below are general rules of thumb.

Sole Traders

Most sole traders should aim to save:

20%–30% of their profits

If your profits are increasing rapidly or you’re a higher-rate taxpayer, consider saving:

30%–40%

This provides a comfortable buffer for:

• Income Tax
• Class 4 National Insurance
• Payments on account

Freelancers

Freelancers often experience fluctuating income.

A sensible approach is to save:

25%–35% of every payment received

Transfer the money immediately into a separate savings account before spending anything else.

Landlords

Rental property owners should also build a tax reserve.

Although mortgage interest relief is restricted, landlords still benefit from various allowable expenses.

Saving around:

20%–30% of rental profits

is generally sensible.

Higher-rate taxpayers may wish to save more.

Company Directors

Company directors usually pay tax differently depending on how they take income.

If you receive:

• Salary
• Dividends
• Rental income
• Other personal income

your required savings will vary.

Many directors benefit from taking professional tax planning advice before deciding how much to save.

Factors That Affect Your Tax Bill

No two taxpayers are identical.

Several factors can increase or decrease your final tax liability.

Business Expenses

The more legitimate business expenses you claim, the lower your taxable profit may be.

Examples include:

• Office costs
• Professional subscriptions
• Software
• Insurance
• Marketing
• Business travel
• Equipment

Maintaining accurate bookkeeping helps ensure you claim everything you’re entitled to.

Pension Contributions

Personal pension contributions can reduce your overall tax liability.

This is often overlooked by business owners who could significantly reduce their tax bill with proper planning.

Student Loans

If you have a student loan, repayments are usually calculated alongside your tax return.

This increases the total amount payable.

Payments on Account

Many people are surprised when HMRC asks for:

• Current year’s tax
• Plus advance payments towards next year’s tax

These advance payments are known as Payments on Account.

This is one of the biggest reasons why first-time taxpayers receive unexpectedly large tax bills.

Best Ways to Keep Aside For Tax Bill Throughout the Year

Instead of scrambling for money in January, create a simple routine.

Open a Separate Savings Account

One of the easiest solutions is to have a dedicated tax savings account.

Each time money enters your business account, immediately transfer your chosen percentage.

This removes temptation and keeps the money safely ring-fenced.

Save Every Time You Get Paid

Don’t wait until month-end.

Common Mistakes People Make

Many taxpayers unknowingly create future financial problems.

Here are some of the most common mistakes.

Spending All Business Income

A healthy business bank balance does not mean all of the money belongs to you.

Some of it belongs to HMRC.

Forgetting Payments on Account

Many people budget only for this year’s tax and forget that HMRC may ask for advance payments.

This often doubles the amount due in January.

Poor Bookkeeping

Missing receipts and incomplete bookkeeping make it difficult to estimate tax accurately.

Keeping records up to date throughout the year provides much greater certainty.

Not Seeking Professional Advice

Every person’s tax position is different.

Professional tax planning often saves significantly more than the cost of obtaining advice.

Practical Example

Imagine you’re a sole trader who earns profits of £50,000.

A sensible approach would be to save approximately 30%.

That means putting aside around:

£15,000

throughout the year.

When your tax bill arrives, you’ll already have the money available instead of needing to find it at the last minute.

If your actual liability is lower, the remaining funds become additional savings or working capital.

What Happens If You Don’t Save?

Failing to prepare can lead to:

• Cash flow problems.
• Borrowing money to pay HMRC.
• Credit card debt.
• Late payment interest.
• Penalties.
• Stress.
• Difficulty growing your business.

Cloud accounting software helps estimate tax throughout the year.

With accurate bookkeeping you can:

• Monitor profits.
• Forecast tax.
• Track expenses.
• Stay MTD compliant.
• Make informed financial decisions.

When Should You Speak to an Accountant?

The earlier, the better.

Professional advice becomes particularly valuable if you:

• Start self-employment.
• Buy rental property.
• Become a company director.
• Have multiple income sources.
• Sell assets.
• Expect profits to increase.
• Receive foreign income.

Good tax planning is proactive—not reactive.

Meeting with an accountant before the tax year ends often creates opportunities to reduce your overall liability legally.
