QUESTIONS
Self-employed tax return questions
Yes. If you are starting out, you must register with HMRC by 5 October after the end of the tax year in which you began trading, then file a Self Assessment return.
It is a £1,000 allowance for trading income. If your gross trading income is £1,000 or less you generally do not need to report it. Above that, you can deduct either the allowance or your actual expenses, whichever is better.
If your profits are above the lower profits limit, you pay Class 4 National Insurance through Self Assessment. We calculate it as part of your return so you see the full bill.
Yes, if you genuinely work from home you can claim either simplified flat-rate amounts or a share of your actual household costs. We choose the method that gives you the better result.
Your fee moves to the band that matches your yearly turnover, sales or expenses. The full list is above, and we confirm your fee before we start.
Our fees start from £199 + VAT and depend on your turnover. We confirm your exact price before any work starts, so there are no surprises.
You can claim costs incurred wholly and exclusively for the business, such as stock and materials, insurance, software, the business share of phone and internet, professional fees, travel and a proportion of home office costs. Simplified flat-rate expenses are available for mileage and working from home.
Turnover is your total business income. Profit is turnover minus allowable expenses. Income Tax and Class 4 National Insurance are charged on profit, not turnover.
If your Self Assessment bill is over £1,000 and less than 80% of your tax was collected at source, HMRC asks for two advance payments towards next year’s bill, due on 31 January and 31 July. Each is normally half of the previous year’s bill.
Yes. We prepare and file late returns for any year and explain the penalties. The sooner a late return is filed, the lower the extra charges. See our late tax return service.
