Sidekick - Limited Company and Self-Employed Accountants

Sidekick are one of the fastest growing accounting services for Self-Employed professionals and Contractors.

Sidekick was created by a team who have over 25 years’ experience providing services to small business owners. Having recognised the way others do things, and feeling that this is outdated, we felt we could offer more. The world is changing, people are busier than ever and the days of putting receipts in an envelope and having a stressful year end are long gone. Life doesn’t have to be stressful w

ith Sidekick, we are here to make running a small business or getting paid as simple and efficient as possible.

That is what one of our clients said when they first came to us.

They were invoicing. Tracking expenses. Doing the basics, but beyond that, they had no idea whether their business was actually structured efficiently, whether they were extracting money in the right way, or whether they were paying more tax than they needed to.

Most self-employed people are in exactly that position. Keeping their head above water but not really in control of the financial side. Getting by rather than getting ahead.

Here is what changes when you work with Sidekick.

We look at your whole picture. Income, expenses, structure, tax position. We make sure you are claiming everything you are entitled to. We make sure your records are clean and current. We handle your self-assessment return and make sure it is optimised, not just filed.

And we check in throughout the year, not just in January.

The goal is simple. You keep more of the money you earn and spend less time thinking about it.

From £35 per month. Get in touch.

This is what one of our clients told us after moving to Sidekick's umbrella service.

"I go to work and do my job. My money is paid into my account on the same date each month, with tax and National Insurance taken care of. I don't even think about it anymore. It just works."

If you are a contractor or freelancer who is tired of chasing invoices, managing your own tax, worrying about whether you have put enough aside, or just wanting the simplicity of knowing exactly when you are getting paid and how much, umbrella is worth understanding.

Through Sidekick's umbrella service, you become an employee of Sidekick. We manage everything. Your pay, your tax, your National Insurance. You submit your timesheets; we handle the rest.

Same date every month.

Get in touch, and we will explain how it works for your situation.

Most people assume incorporating a limited company is complicated and expensive. It does not have to be either.

When you sign up for Sidekick's limited company service, we form your company with Companies House for you, at no extra cost, within 24 hours. You tell us the company name you want; we check it is available, and we handle the whole incorporation process.

That means your company is registered, your registered office is set up, and you are ready to trade, all without spending hours on the Companies House website trying to figure out what you are doing.

From there, your dedicated client manager takes over. Your books are set up on FreeAgent, your payroll is registered if you need it, your VAT registration is handled if you are in scope, and your whole financial setup is put in place properly from day one.

Most people who come to us having incorporated themselves tell us they wish they had done it this way from the start. Getting the foundation right means everything that follows is simpler.

If you are thinking about going limited, get in touch today. We will come back to you within 30 minutes.

There is an option most people do not know about.

If you file your online self-assessment return by 30 December 2026 and you owe less than £3,000 in tax for 2025/26, HMRC can collect it through your PAYE tax code instead of asking for it as a lump sum in January.

That means the amount is spread across your monthly pay throughout 2027/28. It comes out of your payslip automatically. No January payment. No cash flow crunch.

To qualify, you need to be employed as well as self-employed, so that you have a PAYE income for HMRC to adjust your code against. The return has to be filed online by 30 December, not 31 January. File after that date and the option is gone.

It is not right for everyone. If your tax bill is already being reduced by payments on account, or your PAYE income is low, the numbers need checking first.

But if this sounds like it could work for you, the deadline to act is 30 December 2026.

Get in touch, and we will tell you whether it makes sense for your situation.

26/08/2026

Most people think of the 31 January 2027 deadline as just the self-assessment filing date. It is actually three things at once.

Your online tax return for 2025/26 is filed and submitted.

Your balancing payment for 2025/26, which is any tax you owe above what you have already paid through payments on account.

Your first payment on account for 2026/27, which is 50% of your 2025/26 tax bill paid in advance towards next year.

If your tax bill for 2025/26 comes to £6,000, you are not paying £6,000 in January. You are paying £6,000 plus £3,000 on account. £9,000 in total, all due on the same date.

The second payment on account for 2026/27 is then due 31 July 2027.

Knowing this now means you can put money aside as you go rather than finding out in January when it is too late to do anything about it.

Get in touch and we will tell you exactly what to expect.

Quarter two of Making Tax Digital for Income Tax covers 6 July to 5 October 2026. The submission deadline is 7 November 2026.

If you are in scope, meaning your combined gross income from self-employment and property is above £50,000, this applies to you now.

What you need to submit is a summary of your income and expenses for the quarter through HMRC-recognised software. It does not need to be your final figures. It is a quarterly update, not a final set of accounts. But your records do need to be digital and up to date.

If quarter one went in late or did not go in at all, HMRC has confirmed a soft landing for 2026/27, meaning no penalty points this year. That ends when the new tax year starts in April 2027. From that point, the points system kicks in fully.

Quarter three covers 6 October to 5 January 2027 with a deadline of 7 February 2027. Quarter four covers 6 January to 5 April 2027 with a deadline of 7 May 2027.

Getting into a rhythm now makes the rest of the year significantly easier.

Get in touch if you are not set up yet.

If you went self-employed any time in the 2025/26 tax year, the deadline to register with HMRC is 5 October 2026.

Miss it, and you are looking at a failure to notify penalty on top of whatever else you owe. It is one of those things that feels like it can wait and then suddenly it cannot.

Registering is straightforward. You do it online through the HMRC website, and you will receive a Unique Taxpayer Reference in the post within about 10 days. You need that reference to file your return.

Once you are registered, your first self-assessment return for the 2025/26 tax year is due 31 January 2027 online. That is when any tax you owe is also due, along with your first payment on account towards 2026/27 if your bill is over £1,000.

If you started out this year and you are not sure what you need to do or when, that is exactly what we are here for.

Get in touch, and we will walk you through it.

If you rent out property and nobody has talked to you about any of this, keep reading.

Furnished Holiday Lets lost their special tax status from April 2025. If you had properties in that regime, the capital allowances and other benefits that came with it are gone. Rental income from those properties is now taxed the same as standard residential lettings.

Making Tax Digital is now live for landlords with qualifying income above £50,000. That is your combined gross income from property and self-employment before expenses. If that is you, quarterly digital submissions to HMRC are now mandatory, not optional.

If you are below £50,000 right now, the threshold drops to £30,000 in April 2027 and £20,000 in April 2028. Most private landlords in the UK will be in scope by 2028.

Mortgage interest is still not a fully deductible expense. Section 24 means you only get a 20% basic rate tax credit on finance costs, not a full deduction against rental profits. If you are a higher rate taxpayer, that gap is significant.

What you can still claim includes letting agent fees, repairs and maintenance, landlord insurance, utilities if you pay them, professional fees and travel to your properties at 55p per mile.

Capital gains tax on selling a residential investment property is 18% for basic rate taxpayers and 24% for higher and additional rate taxpayers in 2026/27.

If your accountant has not walked you through any of this in the last 12 months, that is a conversation that needs to happen.

Get in touch and we will take a proper look at your position.

This is one of the things that trips new business owners up most.

If you are a sole trader, there is no salary. You draw money from your business whenever you need it. It is all just your personal income at the end of the year. What matters is the profit figure on your tax return, not how much you transferred to your personal account.

If you run a limited company, it works completely differently. You are an employee of your own company. You pay yourself a salary through payroll, taxed through PAYE. Above that, you can take dividends from the company's profit after corporation tax.

The most tax-efficient setup for most limited company directors in 2026/27 is a salary of £12,570 and dividends on top. That uses your personal allowance in full, keeps National Insurance low, and means dividends are taxed at 10.75% in the basic rate band rather than the higher rates that apply to salary.

Getting this wrong is expensive. Getting it right makes a meaningful difference to what you actually keep.

Not sure which structure you are in or whether yours is set up correctly? That is what we are here for.
