Why do documents for a Korean government support program get sent back?

Format trips people up far more often than content does. Common reasons include re-submitting a certificate issued outside the accepted window, sending files loose when the notice asked for one combined document, and attachments that exceed the size limit or use a file type the system does not take. Which rules apply differs from program to program, so reading the official notice and the submission instructions in full is always the most reliable answer.

The notice says to submit everything as a single PDF. How do I do that?

Documents you photographed, such as a copy of your business registration certificate or your bank passbook, need converting to PDF first so every file is the same type. Then upload them to a merge tool in submission order to produce one file. If the order is scrambled the reviewer cannot match your file against their checklist, so follow the list in the notice exactly as printed.

What do I do when the upload says my attachment is too large?

Photos and scans carry high resolution, so they get big quickly. Compressing the PDF clears the limit in most cases, but there is a catch. Squeeze too hard and the text and seal impressions blur, and the file comes back because the content cannot be made out. Reduce only to just under the stated limit, then zoom in on the compressed file and check that digits and seals are still sharp before uploading.

Can I cover the account number on my passbook copy or the number on my ID?

If the notice does not ask for that information, covering it is the safer choice. Which items must stay visible varies by program, though. A document whose whole purpose is verification, such as the account that will receive the funds, may need the account number legible, and covering a required field is itself grounds for rejection. Check the notice and the submission instructions first, and ask the department listed there when it is unclear.

A form needs our company seal and I have no printer. What now?

You can apply it on screen without printing or scanning. Press your physical seal onto white paper, photograph it in good light, remove the background to get a transparent PNG, then position it on the PDF with a stamping tool and save. Keep in mind that a company seal belongs to the corporation, so only someone authorised to use it may create and apply the image. If the procedure also calls for a certificate of registered seal, an image impression may not substitute, so check what the notice requires.

Why Did Mine Come Back? - Government Support Paperwork

Hand-drawn illustration of three steps holding, in order, a scattered pile of documents, a neatly stacked set, and a single bound folder

Anyone assembling government support paperwork for a Korean funding program for the first time tends to stall in the same place. You send everything on the checklist, a request for corrections arrives anyway, and the notice explaining what was missing runs to a single line.

Government support paperwork usually comes back not because a document was left out, but because the form it arrived in did not match the rules.

Two applicants can work from the same checklist and get opposite results, because they stopped at different stages of preparation. Someone who has merely gathered the documents and someone who has matched the submission spec are not sending the same files.

Hand-drawn illustration of three steps: a pile of documents scattered across a desk, the same documents stacked neatly, and finally a single bound folder tucked into an envelope — Same documents, different submissions — it depends how far you took them.

Seven minutes gets you

The three format problems that send applications back, spotted early.
The order of operations that finishes your files without printing or scanning.

Collecting the documents is not the same as being ready. Preparation splits into gathering, standardising the format, and matching the submission spec — and rejections almost always happen in the second and third stage.

Before you start

The official notice is always the final authority

This article covers only what repeats across Korean government support programs regardless of type. The list of required documents, how recently a certificate must have been issued, accepted file types, size limits, and sealing rules all differ by program and by agency.

Read the actual notice and the submission instructions rather than a blog summary or an agency's marketing page, and when something is ambiguous, contact the department named in the notice.

Government support paperwork: which stage are you at?

Readiness falls into three rungs. Climbing higher is not about extra effort so much as looking at something different. Stage one looks at the checklist, stage two at the files, stage three at the submission portal.

Stage 1 · Gathering

Everything on the list is in hand

You have the copy of your business registration certificate, the passbook copy, the application form, and the business plan. The common slip here is reusing an old copy you already had on file.

Note next to each item whether it reflects your current trade name and address, and whether it falls inside the issue window the notice requires — that turns checking into a quick pass.

Stage 2 · Standardising the format

One file type, in submission order

A folder mixing phone photos, word processor files, and PDFs cannot go out as it is. Converting everything to a single type and sorting it into the order on the submission list is what stage two means.

Get this far and a reviewer can walk the checklist against your file line by line. Leave ten loose attachments and that comparison stalls before it starts.

Stage 3 · Matching the submission spec

The upload box will actually accept it

File type, size limit, seal impressions, and which details need covering are all settled. Stage three is about the conditions the submission system imposes, not the content of your documents, so getting caught here just before the deadline leaves no time to fix anything.

Read the submission instructions the first time you open the notice and stage two gets done right from the start.

Stage	What you look at	What goes wrong here
Stage 1	The document checklist	Reusing a copy issued too long ago
Stage 2	File types and order	Photos and documents jumbled together
Stage 3	The portal's conditions	Size limit, missing seal, exposed personal data

Stuck at stage two? Here is the work

Stage two is simple work. Turn scattered material into one file type and bind it in order — that is the whole job. Follow the sequence and you never go near a printer.

Hand-drawn comparison illustration: on the left, photo files and document files scattered at mismatched sizes and orientations; on the right, the same material aligned at one size and bound into a single volume — Unify the file type first, then bind — otherwise the order slips.

Start with the photographed documents: shot your passbook copy or registration certificate on your phone? Send them through image to PDF so every file matches
Cover anything sensitive at this point: privacy masking works on images, so handle it before binding and you never have to backtrack
Bind in submission order: upload to merge PDF in exactly the order the notice lists, and you get one file

When you photograph, work in bright light and fill the frame squarely with the document. Shadows or a tilted angle mean you get it back on the grounds that the content cannot be made out. Documents containing tables suffer most — the number columns smear first.

Three places stage three catches you

If you have made it this far and the upload button still stops you, it is almost always one of the three below. These are also the ones discovered right before the deadline.

Hand-drawn illustration of a bound document set standing before a narrow slot, with a scale, an empty signature line missing its seal, and a blacked-out number field lined up beside it — The submission portal checks three conditions before it looks at content.

Sticking point 1

The attachment exceeds the size limit

Photos and scans run at high resolution, so they balloon fast. PDF compression clears the limit in most cases, but squeezing too hard to hit the number blurs text and seals, and that alone sends it back.

After compressing, zoom in and confirm the digits and seal impressions are still crisp before you upload.

Sticking point 2

The seal line is blank

Application forms and undertakings sometimes require a company seal. Press the physical seal onto white paper, photograph it, make a transparent PNG with background removal, and place it using stamp a PDF — no printing involved.

Bear in mind that only someone authorised to use the company seal may create and apply that image.

Sticking point 3

You cover what should show, and show what should be covered

Information the notice does not ask for is safer covered. The reverse is also true: black out a field whose whole purpose is verification and that becomes the reason for a correction request.

Leave items that need matching visible, such as the account receiving the funds, and confirm which fields are mandatory in the notice and the submission instructions.

Making the next application shorter

Climb to stage three once and the next program moves far faster. Government support paperwork is not built from scratch every time — you are pulling the same materials out again.

Keep the transparent PNG of your seal, PDF versions of recently issued certificates, and the company profile you reuse most in one folder. One caveat: a seal file is dangerous in the wrong hands, so keep it somewhere only you can reach rather than in a shared drive or a group chat.

If you have government support paperwork open on your desk right now, start by getting the order right in merge PDF.

This article offers general practical guidance and does not describe the eligibility requirements of any specific program. Required documents, issue-date windows, accepted file types, size limits, and sealing rules differ by program and by agency, so the relevant official notice and submission instructions are the final authority. Create and use seals and signatures only in your own name or in a name you are duly authorised to represent. Producing one in someone else's name, or in the name of a corporation you have no authority over, and applying it to a document can carry criminal liability. This article reflects the position as of August 2026.
