Accountants for missed self-assessment deadlines
Millions of people need to file self-assessment tax returns in the UK every year, with a decent number who miss the deadline. Here at Caroola, we have a dedicated service to help if you’re one of these people. You need to act quickly, as penalties and interest charges can increase for every day you don’t file. Penalties also exist for late payments.
How we help
Balancing services, payment processing, professional development, and financial admin can be overwhelming, especially when your self-assessment deadline is looming. Payments on account are designed to spread your tax burden out across two instalments. As payments are calculated based on your projected earnings, you may need to make adjustments if your income has changed between different tax years.
Your self-assessment accountant will review your financial position, complete calculations, validate your return, and liaise with HMRC on your behalf. Our goal is to minimise and appeal penalties where possible, and repair any reputational damage with HMRC.
