Worth knowing

Rules that come up in this work

Workplace pensions and auto-enrolment

Auto-enrolment duties begin the day you take on your first employee, not when the Pensions Regulator writes to you. Eligible staff must be enrolled, contributions paid every pay period and re-enrolment carried out every three years. Director-only companies without employment contracts are usually exempt. Fines for non-compliance are fixed and escalating.

Employer National Insurance

Employers pay National Insurance at 15% on each employee's earnings above the £5,000 secondary threshold, following the April 2025 changes. The Employment Allowance offsets up to £10,500 of this for eligible employers, which for a small team often removes the liability entirely, but companies where the director is the only employee do not qualify.

The trading and property allowances

Not every small income needs a tax return. The trading allowance exempts the first £1,000 of self-employment or casual income and the property allowance does the same for rental income, each measured on gross receipts. They cannot be combined with rent-a-room relief on the same income, and claiming the allowance means giving up the expense deduction for that source.

Dormant companies

A dormant company is one with no significant accounting transactions in the year, where the only permitted entries are the payment for shares on incorporation, Companies House fees and penalties. It still files a confirmation statement and simplified dormant accounts every year. A bank charge or an accountant's fee paid from the company ends dormancy and requires full accounts.

The 60-day property CGT return

The 60-day Capital Gains Tax return on residential property is the deadline landlords most often miss, because it falls outside the Self Assessment cycle and runs from completion, not exchange. Private residence relief for periods you lived in the property, plus the final nine months, reduces the gain. Penalties for a late return mirror Self Assessment, starting at £100.

Crypto records and reporting

Crypto tax splits into capital gains on disposals and income on rewards, with different rates and different reporting. The £3,000 annual exempt amount and the 18% and 24% rates apply to gains; staking, mining and airdrop income is taxed at marginal income tax rates. HMRC's nudge letters to holders have increased sharply, and a voluntary disclosure before one arrives is treated far more leniently.

Allowable expenses

An expense is allowable against trading profit if it is incurred wholly and exclusively for the business. Materials, business travel other than ordinary commuting, a proportion of home running costs, software, insurance, professional fees, bank charges and protective clothing qualify. Client entertainment, ordinary clothing, fines and the private share of mixed-use costs do not.

Questions

Self Assessment Tax Returns questions from Leavesden

What if my return is late?

We file late returns at the £179 rescue fee, which includes drafting a reasonable-excuse appeal where the facts support one. The £100 automatic penalty is HMRC's, not ours, and we tell you honestly whether an appeal has a realistic chance before you pay for it.

I have never filed before. Do I need a UTR first?

Yes. If you have not registered we handle the registration as part of the job and HMRC posts your Unique Taxpayer Reference within about ten working days. Start early if your first deadline is close, because HMRC will not accept a return without it.

How quickly can you file once I send my records?

Most straightforward returns are drafted within five working days of receiving complete records and filed the day you approve. In January we prioritise by deadline risk and tell you your slot when you book, so late bookers are not left guessing.

What does the £129 return cover?

A full SA100 with the supplementary pages for one income source, prepared, checked and filed online. Rental income, capital gains or several income sources move you to the £169 or £199 package, and we tell you which applies before we start, never on the invoice.

Which expenses can I claim as a sole trader?

Costs that are wholly and exclusively for the business: materials, business travel other than ordinary commuting, a proportion of home running costs, software, insurance, professional fees and bank charges. If your expenses are under £1,000 the trading allowance may be better, and we check both.

How do payments on account work?

If your bill is over £1,000 and less than 80% of your tax is collected at source, HMRC asks for two advance payments towards next year, due 31 January and 31 July, each half of this year's bill. We calculate both and show you how to reduce them if your income is falling.
