Frequently asked questions

Answers to common questions about Kletta, Making Tax Digital and keeping your books as a sole trader.

Plans and payment

Is Kletta really free?

Kletta Solo is free to use: your books and your tax return cost nothing to prepare. You pay for a filing pass when you send your tax return to HMRC, £34.80 for Self Assessment or £58.80 under Making Tax Digital. Duo and Care include filing.

What does a filing pass cost?

An MTD filing pass is £58.80 and a Self Assessment filing pass £34.80, including VAT. Duo (£120 a year) and Care (£298.80 a year) include filing, so you don’t need a filing pass.

Is Duo free if I’m not in Making Tax Digital yet?

Yes. If you’re not in Making Tax Digital yet, you get Kletta Duo, normally £120 a year, free until your first Making Tax Digital deadline.

Kletta and filing

When can I file?

Filing for a tax year opens on 6 April. Because Kletta builds your return as you go, it can be ready then instead of in January.

Who sends the return to HMRC?

You do. Kletta prepares it and shows the figures with HMRC’s own calculation, and you send it when you are happy.

How is my data kept safe?

Your data is encrypted and stored in the EU/UK, and Kletta complies with UK GDPR. Bank connections run through Plaid, regulated by the FCA.

Making Tax Digital

Is Kletta ready for Making Tax Digital?

Yes. Kletta is HMRC-recognised for Making Tax Digital for Income Tax (MTD ITSA). It keeps the digital records HMRC requires and sends your quarterly updates and tax return.

What is Making Tax Digital (MTD)?

An HMRC programme that requires businesses and landlords to keep digital records and send tax information to HMRC through compatible software.

Who needs to follow MTD for Income Tax?

Sole traders and landlords with self-employment and property income over £50,000 from April 2026, and over £30,000 from April 2027 and over £20,000 from April 2028. VAT-registered businesses already follow MTD for VAT.

What do I need to do under MTD?

Keep your income and expenses digitally, send quarterly updates to HMRC and send your tax return after the tax year.

Can I still use spreadsheets?

Yes, but they need to connect to HMRC through bridging software, which keeps your records in two places. With Kletta your records are digital from the start.

What happens if I miss a deadline?

Each missed deadline adds a penalty point, and at 4 points you get a £200 penalty. In 2026/27 HMRC isn’t giving points for late quarterly updates, but a late tax return still counts. Late payment has its own penalties, plus interest.

Sole traders

What is a sole trader?

The simplest business structure in the UK: you run the business as an individual and are personally responsible for its profits, taxes and debts.

Do I need to register as a sole trader?

Yes, with HMRC for Self Assessment if your gross trading income is more than £1,000 in a tax year.

How much tax does a sole trader pay?

Income Tax on your profits after expenses, and Class 4 National Insurance: 6% on profits between £12,570 and £50,270, and 2% above that.

Do I need to charge VAT?

Only if your VAT-taxable turnover goes over the VAT threshold (£90,000) or you choose to register voluntarily.

What expenses can I claim?

Costs that are wholly and exclusively for your business, such as tools and supplies, travel, business insurance, marketing and part of your home costs if you work from home.

CIS

Can I add CIS statements?

Yes. Add your CIS statements alongside your receipts, and Kletta includes them in your return.

Can Kletta handle CIS deductions correctly?

Yes. You record gross labour, materials, CIS deducted and net paid, and Kletta tracks the CIS deducted and shows how the deductions affect your tax position.

I do CIS work and private jobs. Is that supported?

Yes. Kletta handles CIS income from contractors, invoices to private customers, card payments (e.g. SumUp, Stripe), bank transfers and cash.

Can I manage rental income alongside my CIS work?

Yes, with Kletta Duo and Care. You keep business and property income and expenses separate and see a combined tax overview.
